During the test, five drones simultaneously crossed paths, separated by different altitudes. Two drones flew beyond visual line of sight and three flew within line-of-sight of their operators. More UTM research followed, and it continues today.NASA / Dominic Hart Package delivery drones are coming to our doorsteps in the future, and NASA wants to make sure that when medication or pizza deliveries take to the skies, they will be safe. In July, the Federal Aviation Administration (FAA) for the first time authorized multiple U.S. companies to fly commercial drones in the same airspace without their operators being able to see them the entire flight. Getting to this important step on the way to expanding U.S. commercial drone usage required considerable research into the concept known as flight that is Beyond Visual Line of Sight (BVLOS) – and NASA helped lead the way. For BVLOS flights to become routine, trusted automation technology needs to be built into drone and airspace systems, since pilots or air traffic controllers won’t be able to see all the drones operating at once. To address these challenges, NASA developed several key technologies, most notably Unmanned Aircraft System (UAS) Traffic Management (UTM), which allows for digital sharing of each drone user’s planned flight details. “NASA’s pioneering work on UTM, in collaboration with the FAA and industry, set the stage for safe and scalable small drone flights below 400 feet,” said Parimal Kopardekar, NASA’s Advanced Air Mobility mission integration manager. “This technology is now adopted globally as the key to enabling Beyond Visual Line of Sight drone operations.” With UTM, each drone user can have the same situational awareness of the airspace where drones are flying. This foundation of technology development, led by NASA’s UTM project, allows drones to fly BVLOS today with special FAA approval. Drones can fly BVLOS today at the FAA test site and at some other selected areas with pre-approval from the FAA based on the risks. However, the FAA is working on new regulation to allow BVLOS operations to occur without exemptions and waivers in the future. The NASA UTM team invented a new way to handle the airspace — a style of air traffic management where multiple parties, from government to commercial industry, work together to provide services. These include flight planning, strategic deconfliction before flights take off, communication, surveillance and other focus areas needed for a safe flight. This technology is now being used by the FAA in approved parts of the Dallas area, allowing commercial drone companies to deliver packages using the NASA- originated UTM research. UTM allows for strategic coordination among operators so each company can monitor their own drone flight to ensure that each drone is where it should be along the planned flight path. Test sites like Dallas help the FAA identify requirements needed to safely enable small drone operations nationwide. NASA is also working to ensure that public safety drones have priority when operating in the same airspace with commercial drones. In another BVLOS effort, NASA is using drones to test technology that could be used on air taxis. Each of these efforts brings us one step closer to seeing supplies or packages routinely delivered by drone around the U.S. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Learn more about how drone package delivery works in this FAA video.FAA Facebook logo @NASA@NASAaero@NASA_es @NASA@NASAaero@NASA_es Instagram logo @NASA@NASAaero@NASA_es Linkedin logo @NASA Explore More 3 min read NASA Flips Efficient Wing Concept for Testing Article 6 days ago 4 min read NASA’s C-20A Studies Extreme Weather Events Article 6 days ago 3 min read NASA Experts Share Inspiring Stories of Perseverance to Students Article 1 week ago Keep Exploring Discover More Topics From NASA Missions Drones & You Aeronautics Research Mission Directorate Explore NASA’s History Share Details Last Updated Dec 10, 2024 EditorLillian GipsonContactJim Bankejim.banke@nasa.gov Related TermsDrones & YouAdvanced Air MobilityAeronauticsAeronautics Research Mission DirectorateAir Traffic Management – ExplorationAirspace Operations and Safety ProgramAmes Research CenterArmstrong Flight Research CenterGlenn Research CenterLangley Research CenterUAS Traffic Management View the full article

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) A scientific balloon is inflated during NASA’s 2023 Antarctic campaign in McMurdo, Antarctica. NASA/Scott Battaion NASA’s Scientific Balloon Program has returned to Antarctica’s icy expanse to kick off the annual Antarctic Long-Duration Balloon Campaign, where two balloon flights will carry a total of nine missions to near space. Launch operations will begin mid-December from the agency’s Long Duration Balloon camp located near the U.S. National Science Foundation’s McMurdo Station on the Ross Ice Shelf. “Antarctica is our cornerstone location for long-duration balloon missions, and we always look forward to heading back to ‘the ice,’” said Andrew Hamilton, acting chief of NASA’s Balloon Program Office at the agency’s Wallops Flight Facility in Virginia. “It’s a tremendous effort to stage a campaign like this in such a remote location, and we are grateful for the support provided to us by the U.S. National Science Foundation, New Zealand, and the U.S. Air Force.” This year’s Antarctic campaign includes investigations in astrophysics, space biology, heliospheric research, and upper atmospheric research, along with technology demonstrations. The campaign’s two primary missions include: GAPS (General Anti-Particle Spectrometer), led by Columbia University in New York, is an experiment to detect anti-matter particles produced by dark matter interactions. The anti-particles stemming from these interactions in our galaxy can only be observed from a suborbital platform or in space, since Earth’s atmosphere shields us from the cosmic radiation. GAPS aims to provide an unprecedented level of sensitivity to certain classes of anti-particles, allowing the exploration of a currently unexplored energy regime of the elusive dark matter. Salter Test Flight Universal, led by NASA’s Columbia Scientific Balloon Facility in Palestine, Texas, will test and validate long-duration balloon and subsystems, while supporting several piggyback missions on the flight. Piggyback missions, or smaller payloads, riding along with the Salter Test Flight Universal mission include: MARSBOx (Microbes in Atmosphere for Radiation, Survival, and Biological Outcomes Experiments), led by the U.S. Naval Research Laboratory, will expose melanized fungus, called Aspergillus niger, to the stratosphere’s extreme radiation and temperature fluctuations, low atmospheric pressure, and absence of water — conditions much like the surface of Mars. Knowledge of how this fungus adapts to protect itself in this harsh environment could lead to the development of treatments to protect astronauts from high radiation exposure. EMIDSS-6 (Experimental Module for Iterative Design of Satellite Subsystems 6), led by National Polytechnical Institute − Mexico, is a technological platform with experimental design and operational validation of instrumentation that will collect and store data from the stratospheric environment to contribute to the study of climate change. SPARROW-6 (Sensor Package for Attitude, Rotation, and Relative Observable Winds – 6), led by NASA’s Balloon Program Office at NASA Wallops, will demonstrate relative wind measurements using an ultrasonic anemometer designed for the balloon float environment. WALRUSS (Wallops Atmospheric Light Radiation and Ultraviolet Spectrum Sensor), led by the Balloon Program Office at NASA Wallops, is a technology demonstration of a sensor package capable of measuring the total ultraviolet wavelength spectrum and ozone concentration. INDIGO (INterim Dynamics Instrumentation for Gondolas), led by the Balloon Program Office at NASA Wallops, is a data recorder meant to measure the shock, rotation, and attitude of the gondola during the launch, float, and landing phases of flight. Data will be used to improve understanding of the dynamics of flight and to inform the design of future components and hardware. The remaining two piggyback missions are led by finalists of NASA’s FLOATing DRAGON (Formulate, Lift, Observe, And Testing; Data Recovery And Guided On-board Node) Balloon Challenge, sponsored by the Balloon Program Office at NASA Wallops and managed by the National Institute of Aerospace. The challenge was created for student teams to design, build, and fly an autonomous aerial vehicle, deployed from a gondola during a high-altitude balloon flight. The teams’ student-built data vaults will be safely dropped from around 120,000 feet with the capability to target a specific landing point on the ground to manage risk. The missions participating in the Antarctic campaign are Purdue University’s Purdue DRAGONfly, and University of Notre Dame’s IRIS v3. NASA’s zero-pressure balloons, used in the Antarctic campaign, are made of a thin plastic film and are capable of lifting up to 8,000 pounds of payload and equipment to altitudes above 99.8% of Earth’s atmosphere. Zero-pressure balloons, which typically have a shorter flight duration from the loss of gas during the day-to-night cycle, can support long-duration missions in polar regions during summer. The constant daylight of Antarctica’s austral summer and stable stratospheric wind conditions allow the balloon missions to remain in near space for days to weeks, gathering large amounts of scientific data as they circle the continent. NASA’s Long Duration Balloon camp is located about eight miles from the U.S. National Science Foundation’s McMurdo Station on Antarctica’s Ross Ice Shelf. NASA/Scott Battaion NASA’s Wallops Flight Facility in Virginia manages the agency’s scientific balloon flight program with 10 to 15 flights each year from launch sites worldwide. Peraton, which operates NASA’s Columbia Scientific Balloon Facility in Palestine, Texas, provides mission planning, engineering services, and field operations for NASA’s scientific balloon program. The Columbia team has launched more than 1,700 scientific balloons over some 40 years of operations. NASA’s balloons are fabricated by Aerostar. The NASA Scientific Balloon Program is funded by the NASA Headquarters Science Mission Directorate Astrophysics Division. NASA balloon launch operations from Antarctica receive logistical support from the U.S. National Science Foundation’s Office of Polar Programs, which oversees the U.S. Antarctic Program.

Artist’s concept depicts new research that has expanded our understanding of exoplanet WASP-69 b’s “tail.” NASA/JPL-Caltech/R. Hurt (IPAC) The Planet WASP-69 b The Discovery The exoplanet WASP-69 b has a “tail,” leaving a trail of gas in its wake. Key Takeaway WASP-69 b is slowly losing its atmosphere as light hydrogen and helium particles in the planet’s outer atmosphere escape the planet over time. But those gas particles don’t escape evenly around the planet, instead they are swept into a tail of gas by the stellar wind coming from the planet’s star. Details Hot Jupiters like WASP-69 b are super-hot gas giants orbiting their host stars closely. When radiation coming from a star heats up a planet’s outer atmosphere, the planet can experience photoevaporation, a process in which lightweight gases like hydrogen and helium are heated by this radiation and launched outward into space. Essentially, WASP-69 b’s star strips gas from the planet’s outer atmosphere over time. What’s more, something called the stellar wind can shape this escaping gas into an exoplanetary tail. The stellar wind is a continuous stream of charged particles that flow outwards into space from a star’s outer atmosphere, or corona. On Earth, the Sun’s stellar wind interacts with our planet’s magnetic field which can create beautiful auroras like the Northern Lights. On WASP-69 b, the stellar wind coming from its host star actually shapes the gas escaping from the planet’s outer atmosphere. So, instead of gas just escaping evenly around the planet, “strong stellar winds can sculpt that outflow in tails that trail behind the planet,” said lead author Dakotah Tyler, an astrophysicist at the University of California, Los Angeles, likening this gaseous tail to a comet’s tail. Because this tail is created by the stellar wind, however, that means it’s subject to change. “If the stellar wind were to taper down, then you could imagine that the planet is still losing some of its atmosphere, but it just isn’t getting shaped into the tail,” Tyler said, adding that, without the stellar wind, that gas escaping on all sides of the planet would be spherical and symmetrical. “But if you crank up the stellar wind, that atmosphere then gets sculpted into a tail.” Tyler likened the process to a windsock blowing in the breeze, with the sock forming a more structured shape when the wind picks up and it fills with air. The tail that Tyler and his research team observed on WASP-69 b extended more than 7.5 times the radius of the planet, or over 350,000 miles. But it’s possible that the tail is even longer. The team had to end observations with the telescope before the tail’s signal disappeared, so this measurement is a lower limit on the tail’s true length at the time. However, keep in mind that because the tail is influenced by the stellar wind, changes in the stellar wind could change the tail’s size and shape over time. Additionally changes in the stellar wind influence the tail’s size and shape, but since the tail is visible when illuminated by starlight, changes in stellar activity can also affect tail observations. Exoplanet tails are still a bit mysterious, especially because they are subject to change. The study of exoplanet tails could help scientists to better understand how these tails form as well as the ever-changing relationship between the stellar and planetary atmospheres. Additionally, because these exoplanetary tails are shaped by stellar activity, they could serve as indicators of stellar behavior over time. This could be helpful for scientists as they seek to learn more about the stellar winds of stars other than the star we know the most about, our very own Sun. Fun Facts WASP-69 b is losing a lot of gas — about 200,000 tons per second. But it’s losing this gaseous atmosphere very slowly — so slowly in fact that there is no danger of the planet being totally stripped or disappearing. In general, every billion years, the planet is losing an amount of material that equals the mass of planet Earth. The solar system that WASP-69 b inhabits is about 7 billion years old, so even though the rate of atmosphere loss will vary over time, you might estimate that this planet has lost the equivalent of seven Earths (in mass) of gas over that period. The Discoverers A team of scientists led by Dakotah Tyler of the University of California, Los Angeles published a paper in January, 2024 on their discovery, “WASP-69b’s Escaping Envelope Is Confined to a Tail Extending at Least 7 Rp,” in the journal, “The Astrophysical Journal.” The observations described in this paper were made by Keck/NIRSPEC (NIRSPEC is a spectrograph designed for Keck II).

5 Min Read Scientists Share Early Results from NASA’s Solar Eclipse Experiments On April 8, 2024, a total solar eclipse swept across a narrow portion of the North American continent from Mexico’s Pacific coast to the Atlantic coast of Newfoundland, Canada. This photo was taken from Dallas, Texas. Credits: NASA/Keegan Barber On April 8, 2024, a total solar eclipse swept across North America, from the western shores of Mexico, through the United States, and into northeastern Canada. For the eclipse, NASA helped fund numerous research projects and called upon citizen scientists in support of NASA’s goal to understand how our home planet is affected by the Sun – including, for example, how our star interacts with Earth’s atmosphere and affects radio communications. At a press briefing on Tuesday, Dec. 10, scientists attending the annual meeting of the American Geophysical Union in Washington, D.C., reported some early results from a few of these eclipse experiments. “Scientists and tens of thousands of volunteer observers were stationed throughout the Moon’s shadow,” said Kelly Korreck, eclipse program manager at NASA Headquarters in Washington. “Their efforts were a crucial part of the Heliophysics Big Year – helping us to learn more about the Sun and how it affects Earth’s atmosphere when our star’s light temporarily disappears from view.” Changes in the Corona On April 8, the Citizen CATE 2024 (Continental-America Telescopic Eclipse) project stationed 35 observing teams from local communities from Texas to Maine to capture images of the Sun’s outer atmosphere, or corona, during totality. Their goal is to see how the corona changed as totality swept across the continent. On Dec. 10, Sarah Kovac, the CATE project manager at the Southwest Research Institute in Boulder, Colorado, reported that, while a few teams were stymied by clouds, most observed totality successfully — collecting over 47,000 images in all. These images were taken in polarized light, or light oriented in different directions, to help scientists better understand the processes that shape the corona. This preliminary movie from the Citizen CATE 2024 project stitches together polarized images of the solar corona taken from different sites during the total solar eclipse on April 8, 2024. SwRI/Citizen CATE 2024/Dan Seaton/Derek Lamb Kovac shared the first cut of a movie created from these images. The project is still stitching together all the images into the final, hour-long movie, for release at a later time. “The beauty of CATE 2024 is that we blend cutting-edge professional science with community participants from all walks of life,” Kovac said. “The dedication of every participant made this project possible.” Meanwhile, 50,000 feet above the ground, two NASA WB-57 aircraft chased the eclipse shadow as it raced across the continent, observing above the clouds and extending their time in totality to approximately 6 minutes and 20 seconds. On board were cameras and spectrometers (instruments that analyze different wavelengths of light) built by multiple research teams to study the corona. This image of the total solar eclipse is a combination of 30 50-millisecond exposures taken with a camera mounted on one of NASA’s WB-57 aircraft on April 8, 2024. It was captured in a wavelength of light emitted by ionized iron atoms called Fe XIV. This emission highlights electrified gas, called plasma, at a specific temperature (around 3.2 million degrees Fahrenheit) that often reveals arch-like structures in the corona. B. Justen, O. Mayer, M. Justen, S. Habbal, and M. Druckmuller On Dec. 10, Shadia Habbal of the University of Hawaii, who led one of the teams, reported that their instruments collected valuable data, despite one challenge. Cameras they had mounted on the aircraft’s wings experienced unexpected vibrations, which caused some of the images to be slightly blurred. However, all the cameras captured detailed images of the corona, and the spectrometers, which were located in the nose of the aircraft, were not affected. The results were so successful, scientists are already planning to fly similar experiments on the aircraft again. “The WB-57 is a remarkable platform for eclipse observations that we will try to capitalize on for future eclipses,” Habbal said. Affecting the Atmosphere On April 8, amateur or “ham” radio operators sent and received signals to one another before, during, and after the eclipse as part of the Ham Radio Science Citizen Investigation (HamSCI) Festivals of Eclipse Ionospheric Science. More than 6,350 amateur radio operators generated over 52 million data points to observe how the sudden loss of sunlight during totality affects their radio signals and the ionosphere, an electrified region of Earth’s upper atmosphere. Students from Case Western Reserve University operate radios during the 2024 total solar eclipse. HamSCI/Case Western Reserve University Radio communications inside and outside the path of totality improved at some frequencies (from 1-7 MHz), showing there was a reduction in ionospheric absorption. At higher frequencies (10 MHz and above), communications worsened. Results using another technique, which bounced high-frequency radio waves (3-30 MHz) off the ionosphere, suggests that the ionosphere ascended in altitude during the eclipse and then descended to its normal height afterward. “The project brings ham radio operators into the science community,” said Nathaniel Frissell, a professor at the University of Scranton in Pennsylvania and lead of HamSCI. “Their dedication to their craft made this research possible.”  Also looking at the atmosphere, the Nationwide Eclipse Ballooning Project organized student groups across the U.S. to launch balloons into the shadow of the Moon as it crossed the country in April 2024 and during a solar eclipse in October 2023. Teams flew weather sensors and other instruments to study the atmospheric response to the cold, dark shadow. The eclipse’s shadow was captured from a camera aboard Virginia Tech’s balloon as part of the Nationwide Eclipse Ballooning Project on April 8, 2024. Nationwide Eclipse Ballooning Project/Virginia Tech This research, conducted by over 800 students, confirmed that eclipses can generate ripples in Earth’s atmosphere called atmospheric gravity waves. Just as waves form in a lake when water is disturbed, these waves also form in the atmosphere when air is disturbed. This project, led by Angela Des Jardins of Montana State University in Bozeman, also confirmed the presence of these waves during previous solar eclipses. Scientists think the trigger for these waves is a “hiccup” in the tropopause, a layer in Earth’s atmosphere, similar to an atmospheric effect that is observed during sunset. “Half of the teams had little to no experience ballooning before the project,” said Jie Gong, a team science expert and atmospheric scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “But their hard work and research was vital in this finding.” By Abbey Interrante and Vanessa Thomas NASA’s Goddard Space Flight Center, Greenbelt, Md.

The Space Technology Payload Challenge invites individuals, teams, and organizations to submit applications for systems that advance technology to address one or more of NASA’s shortfalls. These shortfalls identify technology areas where further technology development is required to meet future exploration, science, and other mission needs. In addition, technologies to address these select shortfalls are also potentially well suited for a suborbital or hosted orbital flight demonstration to help mature the innovation. The expectation is that the technology will be tested at the end of the challenge aboard a suborbital vehicle, rocket-powered lander, high altitude balloon, aircraft following a reduced gravity profile (i.e., parabolic flight), or orbital vehicle that can host payloads. The shortfalls selected for this challenge are divided into two groups. The first group is derived from the Space Technology Mission Directorate (STMD) civil space shortfall list. The second group is in partnership with NASA’s Biological and Physical Sciences (BPS) Division and is derived from the Commercially Enabled Rapid Space Science Initiative (CERISS) program needs.  Award: $4,500,000 in total prizes Open Date: December 10, 2024 Close Date: March 4, 2025 For more information, visit: https://www.stpc.nasatechleap.org/ View the full article

NASA/JPL-Caltech Earth planning date: Friday, Dec. 6, 2024 We successfully arrived in our new exploration quadrangle — the Altadena quad — which is named after a town on Earth very near our own Jet Propulsion Laboratory! The names from this quad will recognize the incredible interaction between Altadena and its surrounding environs with the San Andreas and other major faults, which led to the formation of several major mountain ranges, and with the rich human history of the area. The start of our activities in the Altadena quad was fairly typical, including observations both near to and far from the rover, depending on what catches our eye across the terrain. Today’s observations were no exception, but it strikes me that they fit into fairly neat order of magnitude bins that really crystallize how far-reaching (pun intended) Curiosity’s science is. The nearest observation is of the rover itself, with MAHLI placed around 10 centimeters (about 4 inches) from its calibration target for a series of images tracking the amount of dust clinging to the target. One meter (about 39 inches) from the front of the rover, MAHLI and APXS planned an analysis of a small float block, “Icehouse Canyon,” that resembled rocks we saw in Gediz Vallis. MAHLI, APXS, and ChemCam teamed up to analyze the DRT target located on typical bedrock in the workspace at “Sunland,” and ChemCam rastered across one the many veins in the workspace at target “Echo Mountain.” One meter (about one yard) in back of (and underneath) the rover, DAN scheduled multiple analyses that look to provide insight into water in the subsurface. Tens of meters (tens of yards) from the rover, our interest in recording the many veins of this area continued. Mastcam planned three mosaics covering different collections of these long, linear features, some of which are visible in the lower left corner of the image above, to support study of their orientations. Hundreds of meters from the rover, ChemCam looked back at Gediz Vallis, planning RMI mosaics of materials on both Gediz Vallis Ridge and within Gediz Vallis itself. The mosaics add more insight to that which we gained as we traversed through Gediz Vallis as the team tries to interpret the formation of the ridge and valley. Mastcam added coverage of this same area and extended their imaging a bit farther to include a small crater, “Grant Lake,” well south of the rover. Thousands of meters from the rover (five-eighths of a mile, and beyond), ChemCam acquired a mosaic of the wind-sculpted structures that cap Mount Sharp, known as yardangs. Finally, gazing up into the Martian atmosphere that extends tens of thousands of meters into space (6 miles, and multiples beyond that), Navcam planned early morning and midday imaging to assess the amount of dust in the atmosphere and search for clouds and dust devils. ChemCam planned a passive sky observation to measure certain chemical compounds in the atmosphere, and REMS and RAD included their regular schedule of weather and radiation monitoring, respectively. The weekend plan is truly science across the scales!

17 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) On Dec. 8, 1994, NASA announced the selection of its 15th group of astronauts. The diverse group comprised 19 candidates – 10 pilots and nine mission specialists, and included five women, two African Americans, one Asian American, and the first Peruvian-born and Indian-born astronauts. Four international astronauts, one each from Canada and Japan and two from France, joined the group later for astronaut candidate training, following which all 23 became eligible for spaceflight assignment. The two French candidates had previous spaceflight experience in cooperative missions with Russia. All members of the group completed at least one spaceflight, making significant contributions to assembly and maintenance of the space station and carrying out important science missions. Three perished in the Columbia accident. The Group 15 NASA and international astronaut candidates pose for a group photo – front row, Jeffrey S. Ashby, left, Dafydd “Dave” R. Williams, James F.

Bloomfield, Joe F. Edwards, Dominic L.P. Gorie, Rick D. Husband, Steven W. Lindsey, Pamela A. Melroy, Susan L. Still, and Frederick “Rick” W. Sturckow, and mission specialist candidates Michael P. Anderson, Kalpana Chawla, Robert L. Curbeam, Kathryn “Kay” P. Hire, Janet L. Kavandi, Edward T. Lu, Carlos I. Noriega, James F. Reilly, and Steven K. Robinson. A January 1995 agreement among the agencies enabled Canadian Space Agency (CSA) astronaut Dafydd “Dave” R. Williams and Takao Doi of the National Space Development Agency (NASDA), now the Japan Aerospace Exploration Agency, to join the 19 NASA astronauts for training. Another agreement between NASA and the French space agency CNES enabled astronauts Jean-Loup Chrétien and Michel Tognini to also join the group. Both Chrétien and Tognini had previous spaceflight experience through joint agreements with Russia, and their experience proved helpful to NASA in the fledgling Shuttle-Mir Program.

The two French astronauts joined them later. During the yearlong training, the candidates attended classes in applied sciences, space shuttle and space station systems, space medicine, Earth and planetary sciences, and materials sciences. They visited each of the NASA centers to learn about their functions and received instruction in flying the T-38 Talon training aircraft, high-altitude and ground egress systems, survival skills, parasail flight, and scuba. They experienced short-duration weightlessness aboard NASA’s KC-135 aircraft dubbed the Vomit Comet. After completing the astronaut candidate training, they qualified for various technical assignments within the astronaut office leading to assignments to space shuttle crews.

Per tradition, the previous astronaut class provided the nickname for Group 15. Originally, The Class of 1992, The Hogs, dubbed them The Snails because NASA had delayed their announcement. Then after the addition of the two French astronauts, they felt that The Flying Escargots seemed more appropriate. The Group 15 patch included an astronaut pin rising from the Earth, an orbiting space shuttle and space station, and flags of the United States, Canada, France, and Japan.

SkywatchingHomeThe Next Full Moon is the Cold…SkywatchingSkywatching HomeWhat’s UpEclipsesExplore the Night SkyNight Sky NetworkMoreTips and GuidesFAQ 31 Min Read The Next Full Moon is the Cold Moon A full Moon rising over the Wasatch Mountains in Utah on March 15, 2014. Credits: NASA/Bill Dunford The Next Full Moon is the Cold Moon, Frost Moon, or the Winter Moon; the Moon before Yule or the Oak Moon; the Long Night Moon; the Child Moon; the Datta or Dattatreya Jayanti Festival Moon; the Karthika Deepam Festival Moon; Unduvap Poya; and the Chang’e Moon. The next full Moon will be Sunday morning, Dec. 15, 2024, passing opposite the Sun at 4:02 a.m. EST. This will be Saturday evening from Alaska Time westwards to the International Date Line. The Moon will appear full for about three days around this time, from Friday evening through Monday morning, making this a full Moon weekend. The Maine Farmers’ Almanac began publishing Native American names for full Moons in the 1930s. Over time these names have become widely known and used. According to this almanac, as the full Moon in December this is the Cold Moon, due to the long, cold nights. Other names are the Frost Moon (for the frosts as winter nears) or the Winter Moon. As the full Moon before the winter solstice, old European names for this Moon include the Moon before Yule and the Oak Moon. Yule was a three-day winter solstice festival in pre-Christian Europe. In the 10th century King Haakon I associated Yule with Christmas as part of the Christianization of Norway, and this association spread throughout Europe. Some believe that the Oak Moon name ties back to ancient druid traditions of harvesting mistletoe from oak trees, a practice first recorded by the Roman historian Pliny the Elder in the first century CE. The term “druid” may derive from the Proto-Indo-European roots for “oak” and “to see,” suggesting “druid” means “oak knower” or “oak seer.” As the full Moon closest to the winter solstice, this will be the Long Night Moon. The plane of the Moon’s orbit around Earth nearly matches the plane of Earth’s orbit around the Sun. When the path of the Sun appears lowest in the sky for the year, the path of the full Moon opposite the Sun appears near its highest. For the Washington, D.C. area, on Saturday evening into Sunday morning, December 14 to 15, the Moon will be in the sky for a total of 16 hours 1 minute and will reach a maximum altitude of 79.0 degrees (at 11:52 p.m. EST), with 14 hours 33 minutes of this when the Sun is down. The next night, Sunday evening into Monday morning, December 15 to 16, the full Moon will be in the sky slightly longer and will reach higher in the sky, but slightly less of this time will be when the Sun is down. The Moon will be in the sky for a total of 16 hours 3 minutes and will reach a maximum altitude of 79.2 degrees (at 1:54 a.m.), with 14 hours 29 minutes of this when the Sun is down. This also is the Child Moon. Five years ago, then 7-year-old Astrid Hattenbach was walking home from school with her father Henry Throop (a friend and former coworker at NASA Headquarters). When she saw the rising full Moon, she said: “You know what this Moon is called? It’s called a Child Moon. Because the Moon rises at a time that the children, they can see it, because they’re not in bed, and they might even be outside like we are right now.” Henry told me about this and I thought it a perfect name. This year (at least for Washington, D.C. and similar latitudes), the earliest evenings with a full Moon in the sky will be on December 13 through 15, with sunset at 4:44 p.m. EST and evening twilight ending at 5:50 p.m. (on the 13th) or 5:51 p.m. (on the 14th and 15th). For more on the wonder the Moon imbues in the hearts of children (and in all of us) look up Carl Sandburg’s poem “Child Moon.” For Hindus, this full Moon corresponds with Datta Jayanti, also known as Dattatreya Jayanti, a festival commemorating the birth day of the Hindu god Dattatreya (Datta), celebrated on the full Moon day of the month of Margashira. Karthika Deepam is a festival observed by Hindus of Tamil Nadu, Sri Lanka, and Kerala when the nearly full Moon lines up with the Pleiades constellation (Krittikai or Karttikai). This year it will be on Friday, December 13. Some areas celebrate multi-day festivals that include this full Moon. For the Buddhists of Sri Lanka, this is Unduvap Poya. In the third century BCE, Sangamitta Theri, the daughter of Emperor Ashoka and founder of an order of Buddhist nuns in Sri Lanka, is believed to have brought a sapling of the sacred Bodhi Tree, or Bo Tree, to Sri Lanka. The sapling was planted in 288 BCE by King Devanampiya Tissa in the Mahamevnāwa Park in Anuradhapura where it still grows today, where it is believed by some to be the oldest living human-planted tree with a known planting date. We could also call this the Chang’e Moon, after the three Chinese lunar landers that launched and landed on the Moon this time of year. These missions get their name from the Chinese goddess of the Moon, Chang’e, who lived on the Moon with her pet rabbit, Yutu. The Chang’e 3 lander and its companion Yutu rover launched on Dec. 1, 2013, and landed on the Moon a few days later on December 14. The Chang’e 4 lander and Yutu-2 rover launched Dec. 7, 2018, and landed on the Moon on Jan. 3, 2019. The Chang’e 5 lunar sample return mission was launched in 2020 on November 23 (in UTC, November 24 in China’s time zone), collected samples from the Moon, and returned them to Earth on Dec. 16, 2020, humanity’s first lunar sample return since 1976. The Chang’e 6 lunar sample return mission ended the “streak” of December missions by launching on May 3, collecting samples from the Moon, and returning them to Earth on June 25, 2024, humanity’s first lunar sample return from the far side of the Moon. In many traditional Moon-based calendars the full Moons fall on or near the middle of each month. This full Moon is near the middle of the eleventh month of the Chinese year of the Dragon and Jumādā ath-Thāniyah, also known as Jumādā al-ʾĀkhirah, the sixth month of the Islamic year. This full Moon is the middle of Kislev in the Hebrew calendar. Hanukkah begins on the 25th of Kislev (starting this year with sundown on December 25) and ends 8 days later (with sundown on January 2). As usual, the wearing of suitably celebratory celestial attire is encouraged in honor of the full Moon. Bundle up for the cold, then take advantage of these early nightfalls to admire the sky, Moon, planets, and stars! Here are other celestial events between now and the full Moon after next with specific times and angles based on the location of NASA Headquarters in Washington, D.C.: For the Northern Hemisphere, as autumn ends and winter begins, the daily periods of sunlight reach their shortest at the winter solstice and then begin to lengthen again. Our 24-hour clock is based on the average length of the solar day. The winter solstice has the longest night of the year. The winter solstice is sometimes called the “shortest day of the year” (because it has the shortest period of sunlight), but the solar days near the solstice are actually the longest. Because of this, the earliest sunset of the year occurs before the solstice (on December 6 and 7 for the Washington, D.C. area) and the latest sunrise of the year (ignoring Daylight Savings Time) occurs after the solstice on Jan. 4, 2025. On Sunday, December 15, (the day of the full Moon), morning twilight will begin at 6:16 a.m. EST, sunrise will be at 7:20 a.m., solar noon will be at 12:04 p.m. when the Sun will reach its maximum altitude of 27.8 degrees, sunset will be at 4:47 p.m., and evening twilight will end at 5:51 p.m. Saturday, December 21, will be the day of the Northern Hemisphere winter solstice, the astronomical end of fall and start of winter. The winter solstice is the day when the Sun at solar noon is lowest in the sky and the time from sunrise to sunset is shortest for the year. At NASA Headquarters, the time from sunrise to sunset will be 9 hours, 26 minutes, 13 seconds. Solar noon will be at 12:07 p.m. EST when the Sun will reach its lowest daily high, 27.7 degrees. The longest solar day (measured from noon to noon on a sundial) will be from solar noon on December 21 to solar noon on December 22, 29.8 seconds longer than 24 hours. By Monday, Jan. 13, 2025 (the day of the full Moon after next), morning twilight will begin at 6:24 a.m. EST, sunrise will be at 7:26 a.m., solar noon will be at 12:17 p.m. when the Sun will reach its maximum altitude of 29.8 degrees, sunset will be at 5:08 p.m., and evening twilight will end at 6:11 p.m. This will still be a good time for Jupiter and Saturn watching, especially with a backyard telescope. Saturn was at its closest and brightest on September 7 and Jupiter on December 7. With clear skies and a telescope, you should be able to see Jupiter’s four bright moons, Ganymede, Callisto, Europa, and Io, noticeably shifting positions in the course of an evening. For Saturn, you should be able to see Saturn’s rings and its bright moon Titan. The rings are appearing thinner and will be edge-on to Earth in March 2025. We won’t get the “classic” view of Saturn showing off its rings until 2026. During this lunar cycle both of these planets will be shifting towards the west, making them easier to see earlier in the evening sky (and friendlier for backyard stargazing, especially if you have young ones with earlier bedtimes). During this lunar cycle, as twilight ends each evening, Saturn will be shifting from 43 degrees above the southern horizon to 33 degrees above the southwestern horizon while Jupiter will be shifting from 19 degrees above the east-northeastern horizon to 47 degrees above the eastern horizon. Comets Sungrazing comet C/2024 G3 (ATLAS) was discovered in April 2024. It will be passing very near the Sun and might be bright enough to see in the daytime for a short time around its closest approach to the Sun on January 13. The Southern Hemisphere will have the best viewing before and after closest approach (probably requiring binoculars or a telescope), while the Northern Hemisphere will have the best viewing near closest approach. Most likely, this comet will break up and vanish from view as it approaches the Sun like comet C/2024 S1 (ATLAS) did in October. There is only a slight chance that it might survive long enough to be visible near its closest approach. In addition, its visual magnitude might not be bright enough to see in the glow of the nearby Sun. For the Washington, D.C. area, assuming this comet follows its current brightness curve and doesn’t disintegrate, it should be at its brightest the evening of January 12 just before it sets on the southwestern horizon. It will be about 5 degrees to the upper right of the setting Sun. If the horizon is very clear, your best chance of seeing this comet might be after sunset at 5:07 p.m. EST, but before the comet sets about 10 minutes later. Meteor Showers Three meteor showers, the Comae Berenicids (020 COM), the Ursids (015 URS), and the Quadrantids (010 QUA), are expected to peak during this lunar cycle. The Comae Berenicids are a weak but long-lasting shower that will be adding slightly to the background rate of meteors. Under ideal conditions near its peak on December 16 it can produce about 3 visible meteors per hour, but this year moonlight will interfere. The Ursids are expected to peak on the morning of December 22. The MeteorActive app predicts that under bright suburban conditions this shower will only add 1 or 2 meteors per hour to the background rate. On rare occasions this shower can produce major outbursts, as it did in 1945 and 1986 (other outbursts may have been missed due to weather). The International Meteor Organization reports this shower is poorly observed with a narrow peak that seems to fluctuate each year. The radiant for this shower (the point the meteors appear to radiate out from) is high in the northern sky, so this shower can be seen all night from most of the Northern Hemisphere but is not visible from the Southern Hemisphere. This year the Moon will be near its last quarter so the best time to look should be the evenings of December 21 and December 22, between when the sky is completely dark and moonrise. These meteors are caused by debris from the comet 8P/Tuttle entering Earth’s atmosphere at 74,000 mph (33 kilometers per second). The Quadrantids will be active from Dec. 28, 2024 to Jan. 12, 2025. While this is one of the three major annual Northern Hemisphere showers, its narrow peak means it can be difficult to see. This shower radiates out from a point that passes directly over 49 degrees north. It is predicted to have a peak about 4 hours wide centered around 10 a.m. EST on January 3 (when we can’t see them from the Washington, D.C. area). For the D.C. area the MeteorActive app predicts that at about 6 a.m. on the morning of January 3, under bright suburban sky conditions, the peak visible rate from the Quadrantids and all other background sources might reach 14 meteors per hour. Going to a nearby dark sky area (like Sky Meadows State Park in Virginia) might get these rates up to about 34 meteors per hour. Viewing should be better farther west (where the sky will be dark closer to the peak), with the peak viewing probably somewhere in the northern Pacific Ocean. These meteors are caused by debris entering Earth’s atmosphere at 92,000 mph (41 kilometers per second). The source of the debris is uncertain but might be the minor planet 2003 EH1, which in turn may be related to the comet C/1490 Y1 observed by Chinese, Japanese, and Korean astronomers in 1490. If you do go out looking for these meteors, be sure to give your eyes plenty of time to adapt to the dark. Your color-sensing cone cells are concentrated near the center of your view with the more sensitive rod cells on the edge of your view. Since some meteors are faint, you will tend to see more meteors from the “corner of your eye” (which is why you need to view a large part of the sky). Your color vision (cone cells) will adapt to darkness in about 10 minutes, but your night vision rod cells will continue to improve for an hour or more (with most of the improvement in the first 35 to 45 minutes). The more sensitive your eyes are, the more chance you have of seeing meteors. Even a short exposure to light (from passing car headlights, etc.) will start the adaptation over again (so no turning on a light or your cell phone to check what time it is). Evening Sky Highlights On the evening of Saturday, December 14 (the start of the night of the full Moon), as twilight ends (at 5:50 p.m. EST), the rising Moon will be 19 degrees above the east-northeastern horizon with bright planet Jupiter 6 degrees to the right and the bright star Aldebaran father to the right. The brightest planet visible will be Venus at 21 degrees above the southwestern horizon. Next in brightness will be Jupiter. Saturn will be 43 degrees above the southern horizon. The bright star closest to overhead will be Deneb at 61 degrees above the west-northwestern horizon. Deneb (visual magnitude 1.3) is the 19th brightest star in our night sky and is the brightest star in the constellation Cygnus the swan. It is one of the three bright stars of the “Summer Triangle” (along with Vega and Altair). Deneb is about 20 times more massive than our Sun but has used up its hydrogen, becoming a blue-white supergiant about 200 times the diameter of the Sun. If Deneb were where our Sun is, it would extend to about the orbit of Earth. Deneb is about 2,600 light years from us. As this lunar cycle progresses, Jupiter, Saturn and the background of stars will appear to rotate westward around Polaris the pole star each evening (as Earth moves around the Sun). Bright Venus will shift to the left and higher in the sky along the southwestern horizon towards Saturn. January 4 will be the first evening Mars will be above the horizon as twilight ends. The waxing Moon will pass by Venus on January 3, Saturn on January 4, in front of the Pleiades star cluster on January 9, and Jupiter on January 10. On January 12 there is a very slight chance that the sungrazing comet, C/2024 G3 (ATLAS) (discovered in April 2024) might be visible 5 degrees to the upper right of the setting Sun. By the evening of Monday, Jan. 13, 2025 (the evening of the full Moon after next), as twilight ends (at 6:11 P.M. EST), the rising Moon will be 13 degrees above the east-northeastern horizon with the bright planet Mars (the third brightest planet) 2 degrees to the lower left and the bright star Pollux (the brighter of the twin stars in the constellation Gemini the twins) 3 degrees to the upper left of the Moon. The brightest planet visible will be Venus at 29 degrees above the southwestern horizon, with the planet Saturn (fourth brightest) 6 degrees to the upper left of Venus. The second brightest planet, Jupiter, will be 47 degrees above the eastern horizon. The bright star closest to overhead will be Capella at 50 degrees above the east-northeastern horizon. Capella is the 6th brightest star in our night sky and the brightest star in the constellation Auriga the charioteer. Although we see Capella as a single star it is actually four stars (two pairs of stars orbiting each other). Capella is about 43 light-years from us. Morning Sky Highlights On the morning of Sunday, December 15 (the morning of the full Moon), as twilight begins (at 6:16 AM EST), the setting full Moon will be 15 degrees above the west-northwestern horizon. The brightest planet in the sky will be Jupiter, appearing below the Moon at 5 degrees above the horizon. Second in brightness will be Mars at 46 degrees above the western horizon, then Mercury at 4 degrees above the east-southeastern horizon. The bright star appearing closest to overhead will be Regulus at 55 degrees above the southwestern horizon, with Arcturus a close second at 52 degrees above the east-southeastern horizon. Regulus is the 21st brightest star in our night sky and the brightest star in the constellation Leo the lion. The Arabic name for Regulus translates as “the heart of the lion.” Although we see Regulus as a single star, it is actually four stars (two pairs of stars orbiting each other). Regulus is about 79 light years from us. Arcturus is the brightest star in the constellation Boötes the herdsman or plowman and the 4th brightest star in our night sky. It is 36.7 light years from us. While it has about the same mass as our Sun, it is about 2.6 billion years older and has used up its core hydrogen, becoming a red giant 25 times the size and 170 times the brightness of our Sun. One way to identify Arcturus in the night sky is to start at the Big Dipper, then follow the arc of the dipper’s handle as it “arcs towards Arcturus.” As this lunar cycle progresses, Jupiter, Mars, and the background of stars will appear to rotate westward around Polaris the pole star each morning. Mercury too will appear to shift in the same general direction until December 23, after which it will start shifting towards the horizon again. After December 20 Jupiter will no longer be above the horizon as twilight begins. The waning Moon will pass by Pollux on December 17, Mars on December 18, Regulus on December 20, Spica on December 24, and Antares on December 28. Around 6 a.m. on January 3 will likely be the best time to look for the Quadrantids meteor shower. Under suburban conditions it might produce 14 visible meteors per hour. By the morning of Monday, Jan. 13, 2025 (the morning of the full Moon after next), as twilight begins at 6:23 a.m. EST, the setting full Moon will be 11 degrees above the west-northwestern horizon. This will be the first morning the planet Mercury will rise after morning twilight begins (although it will be bright enough to see in the glow of dawn after it rises) leaving Mars at 18 degrees above the west-northwestern horizon the only planet in the sky. The bright star appearing closest to overhead will be Arcturus at 69 degrees above the south-southeastern horizon. Detailed Daily Guide Here is a day-by-day listing of celestial events between now and the full Moon on Jan. 13, 2025. The times and angles are based on the location of NASA Headquarters in Washington, D.C., and some of these details may differ for where you are (I use parentheses to indicate times specific to the D.C. area). If your latitude is significantly different than 39 degrees north (and especially for my Southern Hemisphere readers), I recommend using an astronomy app set for your location or a star-watching guide from a local observatory, news outlet, or astronomy club. Thursday morning, December 12 The first morning the planet Mercury will be above the east-southeastern horizon as morning twilight begins (at 6:14 a.m. EST). Also, on Thursday morning at 8:28 a.m., the Moon will be at perigee, its closest to Earth for this orbit. Friday evening into Saturday morning, December 13 to 14 The Pleiades star cluster will appear near the full Moon. This may best be viewed with binoculars, as the brightness of the full Moon may make it hard to see the stars in this star cluster. As evening twilight ends at 5:50 p.m. EST, the Pleiades will appear 4 degrees to the upper right of the full Moon. By the time the Moon reaches its highest for the night at 10:49 p.m., the Pleiades will be 6 degrees to the right. By about 2 a.m. the Pleiades will be 8 degrees to the lower right of the Moon, and it will continue to separate as the morning progresses. As mentioned last month, one of the three major meteor showers of the year, the Geminids (004 GEM), will peak Saturday morning, December 14. The light of the nearly full Moon will interfere. In a good year, this shower can produce 150 visible meteors per hour under ideal conditions, but this will not be a good year. For the Washington, D.C. area the MeteorActive app predicts that at about 2 a.m. EST, under bright suburban sky conditions, the peak rate from the Geminids and all other background sources might reach 20 meteors per hour. See the meteor summary above for suggestions for meteor viewing. Saturday morning, December 14 The full Moon, the bright planet Jupiter, and the bright star Aldebaran will form a triangle. As Aldebaran sets on the west-northwestern horizon at 6:10 a.m. EST it will be 9 degrees to the lower left of the Moon with Jupiter 7 degrees to the upper left. Morning twilight will begin 6 minutes later. Saturday evening, December 14 The full Moon will have shifted to the other side of Jupiter. Jupiter will be 6 degrees to the right of the Moon as evening twilight ends at 5:50 p.m EST and the pair will separate as the night progresses. Sunday morning, December 15, the next full Moon will be at 4:02 a.m. EST This will be Saturday evening from Alaska Time westwards to the International Date Line. The Moon will appear full for about three days around this time, from Friday evening through Monday morning, making this a full Moon weekend. Monday evening into Tuesday morning, December 16 to 17 The bright star Pollux will appear near the waning gibbous Moon. As Pollux rises above the northeastern horizon at 6:25 p.m. EST, it will be 7 degrees to the lower left of the Moon. By the time the Moon reaches its highest for the night at 1:55 a.m. Pollux will be 4 degrees to the upper left. As morning twilight begins at 6:18 a.m., Pollux will be 3 degrees to the upper right. Tuesday night into Wednesday morning, December 17 to 18 The bright planet Mars, about a month away from its brightest for the year, will appear near the waning gibbous Moon. As Mars rises on the east-northeastern horizon at 7:34 p.m. EST it will be 4 degrees to the lower left of the Moon. By the time the Moon reaches its highest for the night at 2:50 a.m., Mars will be 1 degree to the lower left. When Mars is closest to the Moon a little before 5:00 a.m., it will be a quarter of a degree from the center of the Moon or an eighth of a degree from the edge of the Moon. As morning twilight begins at 6:18 a.m., Mars will be a degree to the lower right of the Moon. The far north of North America and Asia will see the Moon pass in front of Mars. Note that for some areas this occultation will occur during the daytime. Thursday night into Friday morning, December 19 to 20 The bright star Regulus will appear near the waning gibbous Moon. As Regulus rises on the east-northeastern horizon at 9:39 p.m. EST it will be 3 degrees to the lower right of the Moon. As the Moon reaches its highest for the night at 4:26 a.m., Regulus will be 2 degrees to the lower right. Regulus will be 2.5 degrees to the lower right as morning twilight begins at 6:19 a.m. Thursday morning, December 20 This will be the last morning the bright planet Jupiter will be above the west-northwestern horizon as morning twilight begins. Saturday morning, December 21 at 4:20 a.m. EST This is the winter solstice for the Northern Hemisphere, the astronomical end of fall and start of winter. Europeans have used two main ways to divide the year into seasons and define winter. The old Celtic calendar used in much of pre-Christian Europe considered winter to be the quarter of the year with the shortest periods of daylight and the longest periods of night, so that winter started around Halloween and ended around Groundhog Day, hence the origin of these traditions. However, since it takes time for our planet to cool off, the quarter year with the coldest average temperatures starts later than the quarter year with the shortest days. In our modern calendar we approximate this by having winter start on the winter solstice and end on the spring equinox. The last time I checked NOAA data sources, for the Washington, D.C. area at least, the quarter year with the coldest average temperatures started the first week of December and ended the first week of March. Worldwide, many festivals are associated with the winter solstice, including Yule and the Chinese Dongzhi Festival. The solar day from solar noon on Saturday, December 21 to solar noon on Sunday, December 22 will be the longest solar day of the year, 29.8 seconds longer than 24 hours. Sunday morning, December 22 For the Washington, D.C. area, under bright suburban conditions, the MeteorActive app predicts that at about 5:30 a.m. EST the peak rate from the Ursids and all other background sources might reach 5 meteors per hour (with most of these background meteors). Sunday evening, December 22 The waning Moon will appear half-full as it reaches its last quarter at 5:18 p.m. EST. Monday morning, December 23 This will be when the planet Mercury will appear at its highest above the east-southeastern horizon (7 degrees) as morning twilight begins at 6:21 a.m. EST. The bright star about 7 degrees to the lower right of Mercury will be Antares. Early Tuesday morning, December 24, at 2:27 a.m. EST The Moon will be at apogee, its farthest from Earth for this orbit. Also on Tuesday morning, December 24 The bright star Spica will appear near the waning crescent Moon. As Spica rises on the east-southeastern horizon at 1:55 a.m. EST, it will be 6 degrees below the Moon. As morning twilight begins 3.5 hours later at 6:21 a.m., Spica will be 4 degrees to the lower left. For parts of Asia and the Pacific Ocean the Moon will pass in front of Spica. Tuesday night, December 24 This will be when the planet Mercury reaches its greatest angular separation from the Sun as seen from Earth for this apparition (called greatest elongation). Because the angle between the line from the Sun to Mercury and the line of the horizon changes with the seasons, the date when Mercury and the Sun appear farthest apart as seen from Earth is not always the same as when Mercury appears highest above the east-southeastern horizon as morning twilight begins, which will occur on December 23. Wednesday morning, December 25 The Moon will have shifted to the other side of Spica. As the Moon rises on the east-southeastern horizon at 2:23 a.m. EST, Spica will be 7 degrees to the upper right of the Moon, and the pair will separate as the morning progresses. Saturday morning, December 28 The bright star Antares will be 1.5 degrees to the lower left of the waning crescent Moon, with Mercury about 10 degrees to the left of the Moon. The Moon will rise first above the southeastern horizon at 5:32 a.m. EST, followed by Antares 8 minutes later and Mercury 5 minutes after that at 5:45 a.m. As morning twilight begins less than an hour later at 6:23 a.m., the Moon will be 7 degrees above the southeastern horizon. For an area in the mid-Pacific the Moon will block Antares while the sky is dark. Note that for most of the area in the Atlantic, South America, and the Pacific, this occultation will occur in the daytime and only be visible with binoculars or a telescope. Monday afternoon, December 30, at 5:27 p.m. EST This will be the new Moon, when the Moon passes between Earth and the Sun, and it will not be visible from PEarth. The day of, or the day after, the New Moon marks the start of the new month for most lunisolar calendars. The 12th month of the Chinese calendar starts on December 31. Sundown on Tuesday, December 31, will mark the start of Tevet and the start of the seventh day of Hanukkah in the Hebrew calendar. In the Islamic calendar, the months traditionally start with the first sighting of the waxing crescent Moon. Many Muslim communities now follow the Umm al-Qura Calendar of Saudi Arabia, which uses astronomical calculations to start months in a more predictable way. Using this calendar, sundown on Tuesday, December 31, will probably mark the beginning of Rajab, the seventh month of the Islamic calendar. Rajab is one of the four sacred months in which warfare and fighting are forbidden. Friday morning, Jan. 3, 2025 At about 6 a.m. EST for the Washington, D.C. area, under bright suburban sky conditions, the MeteorActive app predicts the peak rate from the Quadrantids and all other background sources might reach 14 meteors per hour. Going to a nearby dark sky area (like Sky Meadows State Park in Virginia) might get these rates up to about 34 meteors per hour. Friday evening, January 3 The bright planet Venus will appear near the waxing crescent Moon. As evening twilight ends at 6:02 p.m. EST the Moon will be 29 degrees above the southwestern horizon with Venus 3.5 degrees to the lower right. As Venus sets on the west southwestern horizon less than 3 hours later at 8:49 p.m., it will be 4.5 degrees to the lower right of the Moon. Saturday morning, January 4 Earth will be at perihelion, the closest we get to the Sun in our orbit. Between perihelion and 6 months later at aphelion there is about a 6.7% difference in the intensity of the sunlight reaching Earth, one of the reasons the seasons in the Southern hemisphere are more extreme than in the Northern Hemisphere. Perihelion is also when Earth is moving the fastest in its orbit around the Sun, so if you run east at local midnight, you will be moving about as fast as you can for your location (in Sun-centered coordinates). Saturday morning, January 4 Ignoring Daylight Saving Time, for the Washington, D.C. area and similar latitudes (I’ve not checked elsewhere), this will be the morning with the latest sunrise of the year at 7:26:56 a.m. EST. Saturday evening, January 4 This will be the first evening the planet Mars will be above the east-northeastern horizon as evening twilight ends, joining Venus, Jupiter, and Saturn in the sky. Mars is approaching its closest and brightest for the year, which will happen on January 15. Also on Saturday evening, January 4 The planet Saturn will appear near the waxing crescent Moon. As evening twilight ends at 6:03 p.m. EST, the Moon will be 40 degrees above the south-southwestern horizon with Saturn 3 degrees to the lower right. As Saturn sets on the western horizon less than 4 hours later at 9:53 p.m., it will be 5 degrees below the Moon. Monday evening, January 6 The Moon will appear half full as it reaches its first quarter at 6:56 p.m. EST (when it will be 56 degrees above the south-southwestern horizon). Tuesday evening, January 7 At 7:07 p.m. EST, the Moon will be at perigee, its closest to Earth for this orbit. Thursday evening, January 9 The waxing gibbous Moon will pass in front of the Pleiades star cluster. This may be viewed best with binoculars, as the brightness of the Moon will make it hard to see the stars in this star cluster. As evening twilight ends at 6:07 p.m. EST, the Pleiades will appear 1 degree to the lower left of the full Moon. Over the next few hours, including as the Moon reaches its highest for the night at 8:37 p.m., the Moon will pass in front of the Pleiades, blocking many of these stars from view. By about midnight the Pleiades will appear about 1 degree below the Moon, and the Moon and the Pleiades will separate as Friday morning progresses. Also on Thursday night, January 9 This will be when the planet Venus reaches its greatest angular separation from the Sun as seen from Earth for this apparition (called greatest elongation). Because the angle between the line from the Sun to Venus and the line of the horizon changes with the seasons, the date when Venus and the Sun appear farthest apart as seen from Earth is not always the same as when it appears highest above the west-southwestern horizon as evening twilight ends, which occurs on January 27. Friday evening, January 10 Jupiter will appear near the waxing gibbous Moon. As evening twilight ends at 6:08 p.m. EST, Jupiter will be 5 degrees to the lower right. As the Moon reaches its highest for the night at 9:37 p.m., Jupiter will be 6 degrees below the Moon. The pair will continue to separate until Jupiter sets Saturday morning at 4:45 a.m. Sunday evening, January 12 There is a very slight chance that the sungrazing comet, C/2024 G3 (ATLAS) (discovered in April 2024) will be visible 5 degrees to the upper right of the setting Sun. Most likely, this comet will not be bright enough to see in the daytime or will break up and vanish from view like comet C/2024 S1 (ATLAS) did in October. The odds are low, but if the horizon is very clear, your best chance of seeing this comet might be after sunset at 5:07 p.m. EST, but before the comet sets about 10 minutes later. The full Moon after next will be Monday evening, January 13, at 5:27 p.m. EST. This will be on Tuesday from the South Africa Time and Eastern European Time zones eastward across the rest of Africa, Europe, Asia, Australia, etc., to the International Date Line in the mid-Pacific. The Moon will appear full for about three days around this time, from Sunday evening (and possibly the last part of Sunday morning) into Wednesday morning. On Monday night the full Moon will appear near and pass in front of the bright planet Mars, with the bright star Pollux above the pair. As evening twilight ends at 6:11 p.m. EST, the three will form a triangle, with Mars 2 degrees to the lower left and Pollux 3 degrees to the upper left of the Moon. For most of the continental USA as well as parts of Africa, Canada, and Mexico, the Moon will pass in front of Mars. Times will vary for other locations, but for NASA Headquarters in Washington, D.C., Mars will vanish behind the bottom of the Moon at about 9:16 p.m. and reappear from behind the upper right of the Moon at about 10:31 p.m. By the time the Moon reaches its highest for the night early on Tuesday morning at 12:37 a.m., Mars will be 1 degree to the right of the Moon and Pollux 5 degrees to the upper right. As morning twilight begins at 6:23 a.m., Mars will be 4 degrees and Pollux 8 degrees to the lower right of the Moon. View the full article

NASA, along with members of the FAA and commercial drone engineers, gathered in the Dallas area May 25, 2024, to view multiple delivery drones operating in a shared airspace beyond visual line of sight using an industry-developed, NASA-originated uncrewed aircraft system traffic management system.NASA NASA’s Uncrewed Aircraft Systems Traffic Management Beyond Visual Line of Sight (UTM BVLOS) subproject aims to support the growing demand for drone flights across the globe. Uncrewed aircraft systems (UAS), or drones, offer an increasing number of services, from package delivery to critical public safety operations, like search and rescue missions. However, without special waivers, these flights are currently limited to visual line of sight – or only as far as the pilot can see – which is roughly no farther than one mile from the operator. As the FAA works to authorize flights beyond this point, NASA is working with industry and the Federal Aviation Administration (FAA) to operationalize an uncrewed traffic management system for these operations. NASA’s UTM Legacy NASA’s Uncrewed Aircraft Systems Traffic Management, or UTM, was first developed at NASA’s Ames Research Center in California’s Silicon Valley in 2013, and enables drones to safely and efficiently integrate into air traffic that is already flying in low-altitude airspace. UTM is based on digital sharing of each user’s planned flight details, ensuring each user has the same situational awareness of the airspace. NASA performed a series of drone flight demonstrations using UTM concepts in rural areas and densely populated cities under the agency’s previous UTM project . And commercial drone companies have since utilized NASA’s UTM concepts and delivery operations in limited areas. Several projects supporting NASA’s Advanced Air Mobility or AAM mission are working on different elements to help make AAM a reality and one of these research areas is automation.NASA / Graphics UTM Today NASA research is a driving force in making routine drone deliveries a reality. The agency is supporting a series of commercial drone package deliveries beyond visual line of sight, some of which kicked off in August 2024 in Dallas, Texas. Commercial operators are using NASA’s UTM-based capabilities during these flights to share data and planned flight routes with other operators in the airspace, detect and avoid hazards, and maintain situational awareness. All of these capabilities allow operators to safely execute their operations in a shared airspace below 400 feet and away from crewed aircraft. These drone operations in Dallas are a collaboration between NASA, the FAA, industry drone operators, public safety operators, and others. These initial flights will help validate UTM capabilities through successful flight operation evaluations and inform the FAA’s rulemaking for safely expanding drone operations beyond visual line of sight. The agency will continue to work with industry and government partners on more complex drone operations in communities across the country. NASA is also working with partners to leverage UTM for other emerging operations, including remotely piloted air cargo delivery and air taxi flights. UTM infrastructure could also support high-altitude operations for expanded scientific research, improved disaster response, and more. NASA UTM BVLOS NASA’s UTM Beyond Visual Line of Site (UTM BVLOS) subproject is leading this effort, under the Air Traffic Management eXploration portfolio within the agency’s Aeronautics Research Mission Directorate. This work is in support of NASA’s Advanced Air Mobility Mission, which seeks to transform our communities by bringing the movement of people and goods off the ground, on demand, and into the sky.

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This animation shows data taken by NASA’s PACE and the international SWOT satellites over a region of the North Atlantic Ocean. PACE captured phytoplankton data on Aug. 8, 2024; layered on top is SWOT sea level data taken on Aug. 7 and 8, 2024. NASA’s Scientific Visualization Studio One Earth satellite can see plankton that photosynthesize. The other measures water surface height. Together, their data reveals how sea life and the ocean are intertwined. The ocean is an engine that drives Earth’s weather patterns and climate and sustains a substantial portion of life on the planet. A new animation based on data from two recently launched missions — NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) and the international Surface Water and Ocean Topography (SWOT) satellites — gives a peek into the heart of that engine. Physical processes, including localized swirling water masses called eddies and the vertical movement of water, can drive nutrient availability in the ocean. In turn, those nutrients determine the location and concentration of tiny floating organisms known as phytoplankton that photosynthesize, converting sunlight into food. These organisms have not only contributed roughly half of Earth’s oxygen since the planet formed, but also support economically important fisheries and help draw carbon out of the atmosphere, locking it away in the deep sea. “We see great opportunity to dramatically accelerate our scientific understanding of our oceans and the significant role they play in our Earth system,” said Karen St. Germain, director of the Earth Science Division at NASA Headquarters in Washington. “This visualization illustrates the potential we have when we begin to integrate measurements from our separate SWOT and PACE ocean missions. Each of those missions is significant on its own. But bringing their data together — the physics from SWOT and the biology from PACE — gives us an even better view of what’s happening in our oceans, how they are changing, and why.” A collaboration between NASA and the French space agency CNES (Centre National d’Études Spatiales), the SWOT’ satellite launched in December 2022 to measure the height of nearly all water on Earth’s surface. It is providing one of the most detailed, comprehensive views yet of the planet’s ocean and its freshwater lakes, reservoirs, and rivers. Launched in February 2024, NASA’s PACE satellite detects and measures the distribution of phytoplankton communities in the ocean. It also provides data on the size, amount, and type of tiny particles called aerosols in Earth’s atmosphere, as well as the height, thickness, and opacity of clouds. “Integrating information across NASA’s Earth System Observatory and its pathfinder missions SWOT and PACE is an exciting new frontier in Earth science,” said Nadya Vinogradova Shiffer, program scientist for SWOT and the Integrated Earth System Observatory at NASA Headquarters. Where Physics and Biology Meet The animation above starts by depicting the orbits of SWOT (orange) and PACE (light blue), then zooms into the North Atlantic Ocean. The first data to appear was acquired by PACE on Aug. 8. It reveals concentrations of chlorophyll-a, a vital pigment for photosynthesis in plants and phytoplankton. Light green and yellow indicate higher concentrations of chlorophyll-a, while blue signals lower concentrations. Next is sea surface height data from SWOT, taken during several passes over the same region between Aug. 7 and 8. Dark blue represents heights that are lower than the mean sea surface height, while dark orange and red represent heights higher than the mean. The contour lines that remain once the color fades from the SWOT data indicate areas of the ocean with the same height, much like the lines on a topographic map indicate areas with the same elevation. The underlying PACE data then cycles through several groups of phytoplankton, starting with picoeukaryotes. Lighter green indicates greater concentrations of this group. The final two groups are cyanobacteria — some of the smallest and most abundant phytoplankton in the ocean — called Prochlorococcus and Synechococcus. For Prochlorococcus, lighter raspberry colors represent higher concentrations. Lighter teal colors for Synechococcus signal greater amounts of the cyanobacteria. The animation shows that higher phytoplankton concentrations on Aug. 8 tended to coincide with areas of lower water height. Eddies that spin counterclockwise in the Northern Hemisphere tend to draw water away from their center. This results in relatively lower sea surface heights in the center that draw up cooler, nutrient-rich water from the deep ocean. These nutrients act like fertilizer, which can boost phytoplankton growth in sunlit waters at the surface. Overlapping SWOT and PACE data enables a better understanding of the connections between ocean dynamics and aquatic ecosystems, which can help improve the management of resources such as fisheries, since phytoplankton form the base of most food chains in the sea. Integrating these kinds of datasets also helps to improve calculations of how much carbon is exchanged between the atmosphere and the ocean. This, in turn, can indicate whether regions of the ocean that absorb excess atmospheric carbon are changing. More About SWOT The SWOT satellite was jointly developed by NASA and CNES, with contributions from the Canadian Space Agency (CSA) and the UK Space Agency. NASA’s Jet Propulsion Laboratory, managed for the agency by Caltech in Pasadena, California, leads the U.S. component of the project. For the flight system payload, NASA provided the Ka-band radar interferometer (KaRIn) instrument, a GPS science receiver, a laser retroreflector, a two-beam microwave radiometer, and NASA instrument operations. The Doppler Orbitography and Radioposition Integrated by Satellite system, the dual frequency Poseidon altimeter (developed by Thales Alenia Space), the KaRIn radio-frequency subsystem (together with Thales Alenia Space and with support from the UK Space Agency), the satellite platform, and ground operations were provided by CNES. The KaRIn high-power transmitter assembly was provided by CSA.

This artist’s concept shows interstellar object 1I/2017 U1 (‘Oumuamua) after its discovery in 2017. While itself not a dark comet, ‘Oumuamua’s motion through the solar system has helped researchers better understand the nature of the 14 dark comets discovered so far.European Southern Observatory / M. Kornmesser These celestial objects look like asteroids but act like comets now come in two flavors. The first dark comet — a celestial object that looks like an asteroid but moves through space like a comet — was reported less than two years ago. Soon after, another six were found. In a new paper, researchers announce the discovery of seven more, doubling the number of known dark comets, and find that they fall into two distinct populations: larger ones that reside in the outer solar system and smaller ones in the inner solar system, with various other traits that set them apart. The findings were published on Monday, Dec. 9, in the Proceedings of the National Academy of Sciences. Scientists got their first inkling that dark comets exist when they noted in a March 2016 study that the trajectory of “asteroid” 2003 RM had moved ever so slightly from its expected orbit. That deviation couldn’t be explained by the typical accelerations of asteroids, like the small acceleration known as the Yarkovsky effect. “When you see that kind of perturbation on a celestial object, it usually means it’s a comet, with volatile material outgassing from its surface giving it a little thrust,” said study coauthor Davide Farnocchia of NASA’s Jet Propulsion Laboratory in Southern California. “But try as we might, we couldn’t find any signs of a comet’s tail. It looked like any other asteroid — just a pinpoint of light. So, for a short while, we had this one weird celestial object that we couldn’t fully figure out.” Weird Celestial Objects Farnocchia and the astronomical community didn’t have to wait long for another piece of the puzzle. The next year, in 2017, a NASA-sponsored telescope discovered history’s first documented celestial object that originated outside our solar system. Not only did 1I/2017 U1 (‘Oumuamua) appear as a single point of light, like an asteroid, its trajectory changed as if it were outgassing volatile material from its surface, like a comet. “‘Oumuamua was surprising in several ways,” said Farnocchia. “The fact that the first object we discovered from interstellar space exhibited similar behaviors to 2003 RM made 2003 RM even more intriguing.” By 2023, researchers had identified seven solar system objects that looked like asteroids but acted like comets. That was enough for the astronomical community to bestow upon them their own celestial object category: “dark comets.” Now, with the finding of seven more of these objects, researchers could start on a new set of questions. “We had a big enough number of dark comets that we could begin asking if there was anything that would differentiate them,” said Darryl Seligman, a postdoctoral fellow in the department of Physics at Michigan State University, East Lansing, and lead author of the new paper. “By analyzing the reflectivity,” or albedo, “and the orbits, we found that our solar system contains two different types of dark comets.” Two Kinds of Dark Comets The study’s authors found that one kind, which they call outer dark comets, have similar characteristics to Jupiter-family comets: They have highly eccentric (or elliptical) orbits and are on the larger side (hundreds of meters or more across). The second group, inner dark comets, reside in the inner solar system (which includes Mercury, Venus, Earth, and Mars), travel in nearly circular orbits, and are on the smaller side (tens of meters or less). Like so many astronomical discoveries, Seligman and Farnocchia’s research not only expands on our knowledge of dark comets, but it also raises several additional questions: Where did dark comets originate? What causes their anomalous acceleration? Could they contain ice? “Dark comets are a new potential source for having delivered the materials to Earth that were necessary for the development of life,” said Seligman. “The more we can learn about them, the better we can understand their role in our planet’s origin.” For more information about asteroids and comets, visit: https://www.jpl.nasa.gov/topics/asteroids/ Small Body Research at JPL NASA Learns More About Interstellar Visitor 'Oumuamua Lesson: Comet on a Stick News Media Contacts Ian J.

Astronaut cognitive performance remains generally stable Researchers found that astronauts on six-month missions to the International Space Station demonstrated generally stable cognitive performance but mild changes in certain areas, including processing speed, working memory, attention, and willingness to take risks. This research provides baseline data that could help identify cognitive changes on future missions and support development of appropriate countermeasures. Research to date has suggested mild decreases in some cognitive performance domains during spaceflight, likely influenced by spaceflight stressors such as radiation and sleep disruption. Longer missions represent greater exposure to these hazards and possible increases in individual vulnerabilities to them. Standard Measures collects a set of psychological and physiological measurements related to human spaceflight risks, including a cognition test battery, from astronauts before, during, and after missions. This paper includes the largest sample of professional astronauts published to date. NASA astronaut Kjell Lindgren performs a cognition test on the space station. NASA Scientific discoveries result from NSF/CASIS research Researchers published highlights of discoveries resulting from a collaboration between the National Science Foundation (NSF) and the Center for the Advancement of Science in Space (CASIS) in support of research on transport phenomena in space. A few examples include: combustion studies that advance our understanding of soot formation, wildfires, flame-spread in buildings, and other fundamental combustion phenomena important in everyday life on Earth heat transfer studies that provide insight into how the physics of evaporation and condensation affect cooling systems on spacecraft and in microelectronics and other industries on the ground fluid dynamics studies validating theories of how drops spread, relevant to the design of thermal management systems and for fluid processing on spacecraft, as well as in medical devices and other ground-based applications Removing gravity enables research on fundamental physical phenomena that is difficult or impossible to conduct on Earth. The investigations that led to the findings above are Spherical Cool Flames, which observed the chemical reactions of cool diffusion flames for insight into combustion and fire behavior; Constrained Vapor Bubble, a study of how evaporation and condensation affect the efficiency of cooling devices; and Capillary Flow Experiment 2, research on wetting (a liquid’s ability to spread across a surface) to support design of better systems to process liquids.

NASA/Joel Kowsky On Dec. 6, 2024, NASA leaders unveiled a portrait of the late Mary W. Jackson, pioneering aerospace engineer and mathematician at NASA’s Langley Research Center. The portrait is displayed at the NASA Headquarters Mary W. Jackson Building in Washington. Jackson accepted a position with the NACA Langley Aeronautical Laboratory’s segregated West Area Computers in 1951, where her supervisor was Dorothy Vaughan. In 1958, she became NASA’s first African American female engineer. In 1979, seeing that the glass ceiling was the rule, rather than the exception for Langley’s female professionals, she made a final, dramatic career change, leaving engineering and voluntarily accepting a reduction-in-grade to serve as an administrator in the Equal Opportunity Specialist field. After undergoing training at NASA Headquarters, she returned to Langley and filled the open position of Langley’s Federal Women’s Program Manager. There, she worked hard to impact the hiring and promotion of the next generation of all of NASA’s female mathematicians, engineers and scientists. Jackson retired from Langley in 1985.

Principal Investigator Suzanne Smrekar is holding the VERITAS logo.NASA/JPL-Caltech Suzanne Smrekar, geophysicist and principal investigator of the agency’s upcoming VERITAS mission to Venus, is NASA JPL’s first recipient of the prestigious award. Suzanne Smrekar, a senior research scientist at NASA’s Jet Propulsion Laboratory in Southern California, received the Fred Whipple Award on Monday, Dec. 9, in Washington at the fall meeting of the American Geophysical Union. Named for astronomer Fred Whipple, the prestigious award recognizes contributions to the field of planetary science. Smrekar also gave the Whipple Lecture “To Venus: A love letter from Earth and beyond” at the event. Smrekar is the principal investigator of NASA’s VERITAS mission, short for Venus Emissivity, Radio science, InSAR, Topography, And Spectroscopy. Slated for launch in the early 2030s, the orbiter will study Venus from surface to core to understand how a rocky planet about the same size as Earth took a very different path, developing into a world covered in volcanic plains and deformed terrain hidden beneath a thick, hot, toxic atmosphere. Smrekar’s passion for modeling and studying how rocky planets evolve led her to a previous stint as deputy principal investigator of NASA’s Mars InSight mission (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport), which revealed new details about the Red Planet’s marsquakes and interior layers, including its crust, mantle, and liquid core. Based at JPL since 1992, Smrekar worked early in her career on NASA’s Magellan mission. “I got to see the first radar images come back from the surface of Venus, and I got to sit around the table with brilliant scientists from around the world examining these bizarre new landscapes, trying to imagine the forces that created them,” she recalled. “It was exhilarating! I was hooked on space exploration, and on Venus!” A recent reexamination of Magellan data found evidence of active volcanism on the planet, and additional indirect evidence of activity, based on estimates of the heat coming out of the planet’s interior from specific tectonic features, has only added to the eagerness to explore Venus. Managed by JPL, VERITAS will study the planet in concert with NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) mission, which is managed by NASA’s Goddard Spaceflight Center in Greenbelt, Maryland, and is also launching in the early 2030s.

Members belonging to one of three teams from Oakwood School aim their devices — armed with chocolate-coated-peanut candies — at a target during JPL’s annual Invention Challenge on Dec. 6.NASA/JPL-Caltech Teams competed with homemade devices to try to launch 50 peanut candies in 60 seconds into a target container.NASA/JPL-Caltech More points were awarded for successfully landing the candy into the highest, smallest level of the triangular Plexiglas target — not an easy task.NASA/JPL-Caltech Treats went flying through the air by the dozens at the annual Invention Challenge at NASA’s Jet Propulsion Laboratory. The 25th Invention Challenge at NASA’s Jet Propulsion Laboratory in Southern California, which welcomed more than 200 students to compete using home-built devices, was pretty sweet this year. Literally. That’s because the challenge at the Friday, Dec. 6, competition was to construct an automated machine that would launch, within 60 seconds, 50 chocolate-coated-peanut candies over a barrier and into a triangular Plexiglas container 16 feet (5 meters) away. The mood was tense as teachers, parents, and JPL employees watched the “Peanut Candy Toss Contest” from the sidelines, some of them eating the ammunition. Students on 21 teams from Los Angeles and Orange county middle and high schools turned to catapults, slingshots, flywheels, springs, and massive rubber bands. There was lots of PVC piping. A giant device shaped like a blue bunny shot candy out of its nose with the help of an air compressor, while other entries relied on leaf blowers and vacuums. A team from Santa Monica High School won the 2024 Invention Challenge at JPL on Dec. 6 with a device was based on a crossbow.NASA/JPL-Caltech Some were more successful than others. Ultimately, it was an old-school design that won first place for a team from Santa Monica High School: a modified crossbow. “I tried to come up with something that was historically tried and true,” said Steele Winterer, a senior on the team who produced the initial design. Like his teammates, Steele is in the school’s engineering program and helped build the device during class. He described the process as “nerve-wracking,” “messy,” and “disorganized,” but everyone found their role as the design was refined. Second and third place went to teams from Oakwood School in North Hollywood, which both took a firing-line approach, using four parallel wooden devices, with one student per device firing after each other in quick succession. Two regional Invention Challenges held at Costa Mesa High School and Augustus Hawkins High School in South L.A. last month had winnowed the field to the 21 teams invited to the final event at JPL. At the finals, three JPL-sponsored teams from out-of-state schools and two teams that included adult engineers faced off in a parallel competition. In this second competition group, retired JPL engineer Alan DeVault took first place, followed by Boston Charter School of Science coming in second, and Centaurus High School from Colorado in third. Competing with a wooden device at the 2024 Invention Challenge, retired JPL engineer and longtime participant Alan DeVault won first place among JPL-sponsored teams, which included professionals and out-of-state students. Challenge organizer Paul MacNeal kneels at right.NASA/JPL-Caltech Held since 1998 (with a two-year break during the COVID-19 pandemic), the contest was designed by JPL mechanical engineer Paul MacNeal to inspire students to discover a love for building things and solving problems. Student teams spend months designing, constructing, and testing their devices to try to win the new challenge that MacNeal comes up with each year. “When student teams come to the finals, they are engaged just as engineers are engaged in the work we do here at JPL,” MacNeal said. “It’s engineering for the joy of it. It’s problem-solving but it’s also team building. And it’s unique because the rules change every year. The student teams get to see JPL engineering teams compete side by side. I started this contest to show students that engineering is fun!” The event is supported by dozens of volunteers from JPL, which is managed by Caltech in Pasadena for NASA.

Curiosity acquired this image using its Right Navigation Camera on sol 4383 — Martian day 4,383 of the Mars Science Laboratory mission — on Dec. 4, 2024, at 13:07:53 UTC. NASA/JPL-Caltech Earth planning date: Wednesday, Dec. 4, 2024 As the Curiosity rover climbs west toward the broad saddle separating Gediz Vallis from its neighboring canyon on the slopes of Mount Sharp, the rover is also approaching the edge of its current geological quadrangle or “quad” map on Mars. The current quad, designated “Bishop,” has meant that all of the targets studied by Curiosity since August 2023 have been named after places of geological interest near Bishop, California, on Earth. The Earthly Bishop quad includes locales in the Sierra Nevada, Owens Valley, and Inyo/White Mountains of California. The team has taken great pleasure in visiting some of Curiosity’s target namesakes during the past year during their off hours, practicing geology while enjoying lovely mountains, lakes, and deserts. However, in the next few plans, readers of this blog will see a different target naming scheme for Curiosity targets. Previous quads have honored regions of Scotland and Brazil, among other places. Read “Mission Update” for Friday, Dec. 6, or Monday, Dec. 9, to find out what the next Martian quad theme will be! Curiosity’s drive on Monday completed successfully. The quote of the day during planning was, “I wish all SRAPs were this easy!” The translation is that all six of Curiosity’s wheels are firmly seated on solid ground, ensuring that the rover will not “pop a wheelie” when the heavy robotic arm reaches out to take close-ups of the nearby rock formations. This paves the way for a very full sol of science investigations prior to the next drive. This plan’s science emphasis is on fractures and light-colored veins in the rocks, indicating that cracks in the rocks experienced groundwater intrusion at some point in the distant past. On sol 4384, APXS and MAHLI will study “Three Brothers.” This is a vertical vein with a tricky arm approach, and MAHLI will use rotational stereo imaging to get a 3D perspective of it at close range. “Three Brothers” is named for a monumental set of peaks on the north side of Yosemite Valley. John Muir considered the view from the northernmost peak to be the best view of Yosemite Valley. MAHLI will also obtain finely detailed images of “Placerville,” a set of small pebbles named for the famous California Gold Rush town. ChemCam will do laser spectroscopy of a vein network in target “Cyclone Meadow,” honoring a lovely alpine meadow at around 9,400 feet in the Southern Sierra Nevada. ChemCam will also take telescopic RMI images of the bright “yardang” wind-eroded upper layers of Mount Sharp seen in the distance in the accompanying Navcam image. Mastcam will obtain before/after high resolution imaging of the laser target, as well as a large 22×1 stereo mosaic of “Dusy Branch,” named for Dusy Branch, a mountain stream flowing into the Bishop Creek canyon. Mastcam will also take smaller mosaics of the vein structures in “Groveland,” named for the western gateway town of Yosemite National Park, as well as images of red pebbles and exotic cobbles. Following that science block, Curiosity will drive 43 meters (about 141 feet) toward the west, ending with a MARDI image in addition to the usual post-drive image panoramas. On sol 4384, ChemCam and Navcam will be used together to obtain AEGIS observations of nearby bedrock. Atmospheric observations of dust opacity, clouds, and dust devils will complete the science for this plan. The next plan will see Curiosity drive uphill to the west and away from our beloved Bishop quad.
