First Commercial Moon Launch: Astrobotic Peregrine Mission 1 (Official NASA Broadcast)

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) El avión de investigación X-59 de la NASA se trasladó de su lugar de construcción a la línea de vuelo -o el espacio entre el hangar y la pista- en Lockheed Martin Skunk Works, en Palmdale (California), el 16 de junio de 2023. El traslado permitió al equipo del X-59 realizar pruebas de seguridad y estructurales, pasos críticos hacia el primer vuelo.Lockheed Martin Lee esta historia en inglés aquí. La misión Quesst de la NASA ha ajustado la fecha prevista para el primer vuelo de su avión supersónico silencioso X-59 a 2024. El X-59, un avión experimental único en su clase, ha requerido una compleja labor de ingeniería por parte de los investigadores de la NASA que trabajan con el contratista principal Lockheed Martin Skunk Works. Además del diseño de la aeronave, el X-59 también combina nueva tecnología con sistemas y componentes de múltiples aeronaves ya establecidas, como su tren de aterrizaje procedente de un F-16 y su sistema de soporte vital adaptado de un F-15. Para poder desarrollar esta aeronave única, el equipo de Quesst está trabajando en varios retos técnicos identificados a lo largo de 2023, cuando estaba previsto que el X-59 realizara su primer vuelo. Se necesita más tiempo para integrar plenamente los sistemas en la aeronave y garantizar que funcionen juntos como se espera. El equipo también está resolviendo problemas intermitentes con algunos de los ordenadores redundantes de seguridad que controlan los sistemas de la aeronave. Quesst realizó progresos constantes hacia el vuelo durante el pasado año. El equipo dio los últimos toques a la estructura de la cola del X-59, lo que les permitió finalizar su cableado eléctrico y continuar con las pruebas críticas en tierra, y trasladarlo desde sus instalaciones de ensamblaje a la línea de vuelo para realizar pruebas estructurales. El X-59 demostrará la capacidad de volar supersónicamente, es decir, más rápido que la velocidad del sonido, mientras reduce el normalmente fuerte estallido sónico, a un golpe más leve o silencioso. La NASA tiene previsto volar el X-59 sobre varias comunidades para obtener datos sobre cómo notan los residentes el sonido que hace. La agencia facilitará esa información a los organismos reguladores estadounidenses e internacionales para que modifiquen las normas que actualmente prohíben los vuelos supersónicos comerciales sobre tierra. Las principales prioridades de la NASA para cualquier misión son la seguridad y garantizar el éxito. Para Quesst, eso significa no sólo estar seguro de que el X-59 es seguro antes de volar, sino seguro a largo plazo y confiable durante la fase de pruebas comunitarias. La aeronave está siendo examinada actualmente en pruebas integradas, que deben completarse antes de que vuele. En cuanto finalice esta fase, la aeronave continuará su viaje con una revisión de preparación para el vuelo, momento en el que la NASA tiene previsto publicar un calendario más específico para el primer vuelo. Quesst es una misión con el potencial de revolucionar los viajes de la aviación comercial al reducir drásticamente el tiempo de viaje. Un vuelo seguro y fiable del X-59 es fundamental para que la NASA consiga esos beneficios. La agencia está comprometida con un proceso exhaustivo de revisión y pruebas que redunde en el éxito de esa misión.

3 min read January’s Night Sky Notes: Connecting the ‘Dots’ with Asterisms by Kat Troche of the Astronomical Society of the Pacific In our December Night Sky Notes, we mentioned that the Orion constellation has a distinct hourglass shape that makes it easy to spot in the night sky. But what if we told you that this is not the complete constellation, but rather, an asterism? An asterism is a pattern of stars in the night sky, forming shapes that make picking out constellations easy. Cultures throughout history have created these patterns as part of storytelling, honoring ancestors, and timekeeping. Orion’s hourglass is just one of many examples of this, but did you know Orion’s brightest knee is part of another asterism that spans six constellations, weaving together the Winter night sky? Many asterisms feature bright stars that are easily visible to the naked eye. Identify these key stars, and then connect the dots to reveal the shape. Asterisms Through the Seasons Stars that make up the Winter Circle, as seen on January 1, 2024 Sky Safari Try looking for these asterisms this season and beyond: Winter Circle – this asterism, also known as the Winter Hexagon, makes up a large portion of the Winter sky using stars Rigel, Aldebaran, Capella, Pollux, Procyon, and Sirius as its points. Similarly, the Winter Triangle can be found using Procyon, Sirius, and Betelgeuse as points. Orion’s Belt is also considered an asterism. Diamond of Virgo – this springtime asterism consists of the following stars: Arcturus, in the constellation Boötes; Cor Caroli, in Canes Venatici; Denebola in Leo, and Spica in Virgo. Sparkling at the center of this diamond is the bright cluster Coma Berenices, or Bernice’s Hair – an ancient asterism turned constellation! Summer Triangle – as the nights warm up, the Summer Triangle dominates the heavens. Comprising the bright stars Vega in Lyra, Deneb in Cygnus, and Altair in Aquila, this prominent asterism is the inspiration behind the cultural festival Tanabata. Also found is Cygnus the Swan, which makes up the Northern Cross asterism. Great Square of Pegasus – by Autumn, the Great Square of Pegasus can be seen. This square-shaped asterism takes up a large portion of the sky, and consists of the stars: Scheat, Alpheratz, Markab and Algenib. This image shows the region around the Hyades star cluster, the nearest open cluster to us. The Hyades cluster is very well-studied due to its location, but previous searches for planets have produced only one. A new study led by Jay Farihi of the University of Cambridge, UK, has now found the atmospheres of two burnt-out stars in this cluster — known as white dwarfs — to be “polluted” by rocky debris circling the star. Inset, the locations of these white dwarf stars are indicated — stars known as WD 0421+162, and WD 0431+126. NASA, ESA, STScI, and Z. Levay (STScI) Tracing these outlines can guide you to objects like galaxies and star clusters. The Hyades, for example, is an open star cluster in the Taurus constellation with evidence of rocky planetary debris. In 2013, Hubble Space Telescope’s Cosmic Origins Spectrograph was responsible for breaking down light into individual components. This observation detected low levels of carbon and silicon – a major chemical for planetary bodies. The Hyades can be found just outside the Winter Circle and is a favorite of both amateur and professional astronomers alike. How to Spot Asterisms Use Star Maps and Star Apps – Using star maps or stargazing apps can help familiarize yourself with the constellations and asterisms of the night sky. Get Familiar with Constellations – Learning the major constellations and their broader shapes visible each season will make spotting asterisms easier. Use Celestial Landmarks –Orient yourself by using bright stars, or recognizable constellations. This will help you navigate the night sky and pinpoint specific asterisms. Vega in the Lyra constellation is a great example of this.

The VIPER team is hard at work building the flight vehicle that will be going to the surface of the Moon this time next year! In fact, we’re about halfway through the build, and you can interactively watch the process and hear from experts on the team, in various livestreams throughout the process. All the science instrument teams have delivered their payloads to the VIPER Systems Integration & Test team, which will install them into the actual flight rover; in fact, all but one is already installed! This was a huge milestone over the past summer, and a frequent sticking point for many flight projects. I’m happy to have all the birds in the nest! We also have taken delivery of most of the key pieces of hardware we acquired from our various external vendors. This is a very important milestone as well, since a large number of vendors of critical components have been quite behind schedule in their deliveries to the project, due to pandemic-era supply chain issues that continue to reverberate throughout the industry in some unexpected ways. It is good to have VIPER past this point in development, where we can now focus on bringing everything together into a functioning rover. So now that we are building the flight article, we are able to see precisely how well our design plans are working in reality. There have been some reveals in the first half of the rover build, which we’ve had to navigate, including connector issues from vendors, where we’ve discovered and corrected some design and Foreign Object Debris issues, which prevented connectors from reliably working. We’ve also found some unexpected performance characteristics revealed by some vendor hardware, which we have had to then fold into our plans for how we operate VIPER…These issues and solutions are all part of the challenging process of building a flight article, and ensuring it can survive the very harsh environment of launch, landing, and operations on the lunar surface. Once the team completes the flight rover assembly, the next step will be to test that rover in the kinds of environments it will see on the mission. This activity will be our primary focus in 2024, and our final step prior to delivering VIPER for launch integration. Go VIPER! – Dan Andrews, VIPER Project Manager View the full article

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Langley’s Navigation Doppler Lidar is a critical landing system on the Astrobotic Peregrine Mission 1, scheduled to launch to the Moon Jan. 8 from Cape Canaveral in Florida.Image credit: NASA Hampton, Virginia — Media is invited to learn about two technologies developed at NASA’s Langley Research Center in Hampton, Virginia, that will launch to the Moon in the coming weeks aboard two flights under NASA’s Commercial Lunar Payload Services (CLPS) initiative. During an event at Langley 9:30 a.m. Thursday, Jan. 4, researchers will discuss the following groundbreaking technologies developed at the center: • Navigation Doppler Lidar (NDL), a laser-based sensor capable of providing precision vector velocity and altitude of space vehicles. NDL data is used to precisely navigate the vehicle and execute a gentle touchdown on the surface of the Moon, Mars, or other destinations in the solar system. • Stereo Cameras for Lunar Plume-Surface Studies (SCALPSS), an array of small cameras placed around a lunar lander to take images of the interaction between the lander’s engine plume and the Moon’s surface. This will help researchers more accurately predict the effects from landing larger, heavier payloads in proximity to one other on the Moon and eventually Mars. Media interested in attending should contact Joe Atkinson at joseph.s.atkinson@nasa.gov no later than noon, Wednesday, Jan. 3. NDL is currently scheduled to launch from Kennedy Space Center in Florida no earlier than Jan. 8 on Astrobotics’ Peregrine 1 lander aboard a United Launch Alliance Vulcan Centaur rocket. Though this launch is part of NASA’s CLPS program, NDL is a critical system provided to Astrobotic by NASA and is not considered a CLPS payload. Peregrine 1 is expected to land on the Moon in late February. NDL and SCALPSS 1.0 are currently scheduled to launch from Kennedy Space Center in Florida in February on Intuitive Machines’ Nova-C lander aboard a SpaceX Falcon 9 rocket. Both NDL and SCALPSS 1.0 are NASA CLPS payloads on this flight. Transit time to the Moon will take 4 to 5 days. These CLPS flights will mark the United States’ first return to the Moon’s surface since the Apollo era. Commercial deliveries to the lunar surface with several providers continue to be part of NASA’s exploration efforts. Future CLPS deliveries could include more science experiments and technology demonstrations that further support the agency’s Artemis program.

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Earlier this year, NASA’s Wallops Flight Facility reaffirmed a 25-year relationship with the Virginia Space Flight Academy (VASFA) through the signing of a new Space Act Agreement. This formal partnership provides outreach opportunities for youth, including a residential space adventure camp each summer. “Wallops is proud to continue our 25-year partnership with VASFA,” said Wallops Director David Pierce. “The camp programs bring local and regional youth to the facility and our subject matter experts look forward to providing behind-the-scenes tours to support the development of the next generation of aerospace professionals.” VASFA campers attend behind the scenes tours of the facility, and learn from different subject matter experts in each location- including the Range Control CenterVirginia Space Flight Academy VASFA was launched in 1998 as one of six projects initiated by the Eastern Shore Regional Partnership. The goal was to offer quality summer camp experiences for local youth by leveraging the high-tech activities being conducted at Wallops, the Virginia Spaceport Authority (then known as the Virginia Commercial Space Flight Authority), NOAA (National Oceanic and Atmospheric Administration), and the United States Navy. Based on the success of the pilot camps, the nonprofit organization was officially established in 2000 and has continued to lead the program. Two summer camp participants work together during a robotics challengeVirginia Space Flight Academy Since then, over 6,000 youth have attended summer camp, with many campers returning to camp as staff. Camp staff members have had the opportunity to leverage their camp experiences to secure internships and employment with NASA and other aerospace partners. An additional 1,000 students have been served by a new series of year-round STEM Academy programming that was launched in 2021. Virginia Space Flight Academy campers and staff celebrate being honored with a Spirit of Virginia award at the end of a camp graduation ceremony.NASA/ Jamie Adkins During the 2023 summer camp season, campers had the opportunity to participate in a few unique experiences. At the July 28 Advanced Aerospace Camp graduation ceremony, the campers and their families were joined by Virginia Governor Glenn Youngkin and First Lady Suzanne S. Youngkin as they presented VASFA with the Spirit of Virginia award. This award recognizes unique qualities and standout achievements across the Commonwealth and salutes Virginians for their uncommon contributions in private industries, education, culture, the arts, and philanthropy. The following week, Advanced Coding and Robotics campers were treated to a rocket launch viewing event during the Northrop Grumman’s 19th cargo resupply launch to the International Space Station aboard the Antares rocket from Wallops Island, Virginia.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) While stationary for two weeks during Mars solar conjunction in November 2023, NASA’s Curiosity rover used its front and rear black-and-white Hazcams to capture 12 hours of a Martian day. The rover’s shadow is visible on the surface in these images taken by the front Hazcam. Videos from the rover show its shadow moving across the Martian surface during a 12-hour sequence while Curiosity remained parked. When NASA’s Curiosity Mars rover isn’t on the move, it works pretty well as a sundial, as seen in two black-and-white videos recorded on Nov. 8, the 4,002nd Martian day, or sol, of the mission. The rover captured its own shadow shifting across the surface of Mars using its black-and-white Hazard-Avoidance Cameras, or Hazcams. Instructions to record the videos were part of the last set of commands beamed up to Curiosity just before the start of Mars solar conjunction, a period when the Sun is between Earth and Mars. Because plasma from the Sun can interfere with radio communications, missions hold off on sending commands to Mars spacecraft for several weeks during this time. (The missions weren’t totally out of contact: They still radioed back regular health check-ins throughout conjunction.) Rover drivers normally rely on Curiosity’s Hazcams to spot rocks, slopes, and other hazards that may be risky to traverse. But because the rover’s other activities were intentionally scaled back just prior to conjunction, the team decided to use the Hazcams to record 12 hours of snapshots for the first time, hoping to capture clouds or dust devils that could reveal more about the Red Planet’s weather. When the images came down to Earth after conjunction, scientists didn’t see any weather of note, but the pair of 25-frame videos they put together do capture the passage of time. Extending from 5:30 a.m. to 5:30 p.m. local time, the videos show Curiosity’s silhouette shifting as the day moves from morning to afternoon to evening. The first video, featuring images from the front Hazcam, looks southeast along Gediz Vallis, a valley found on Mount Sharp. Curiosity has been ascending the base of the 3-mile-tall (5-kilometer-tall) mountain, which sits in Gale Crater, since 2014. As the sky brightens during sunrise, the shadow of the rover’s 7-foot (2-meter) robotic arm moves to the left, and Curiosity’s front wheels emerge from the darkness on either side of the frame. Also becoming visible at left is a circular calibration target mounted on the shoulder of the robotic arm. Engineers use the target to test the accuracy of the Alpha Particle X-ray Spectrometer, an instrument that detects chemical elements on the Martian surface. In the middle of the day, the front Hazcam’s autoexposure algorithm settles on exposure times of around one-third of a second. By nightfall, that exposure time grows to more than a minute, causing the typical sensor noise known as “hot pixels” that appears as white snow across the final image. Curiosity’s rear Hazcam captured the shadow of the back of the rover in this 12-hour view looking toward the floor of Gale Crater. A variety of factors caused several image artifacts, including a black speck, the distorted appearance of the Sun, and the rows of white pixels that streak out from the Sun.NASA/JPL-Caltech The second video shows the view of the rear Hazcam as it looks northwest down the slopes of Mount Sharp to the floor of Gale Crater. The rover’s right rear wheel is visible, along with the shadow of Curiosity’s power system. A small black artifact that appears at the left midway through the video, during the 17th frame, resulted from a cosmic ray hitting the camera sensor. Likewise, the bright flashing and other noise at the end of the video are the result of heat from the spacecraft’s power system affecting the Hazcam’s image sensor. These images have been re-projected to correct the wide-angle lenses of the Hazcams. The speckled appearance of the images, especially prominent in the rear-camera video, is due to 11 years of Martian dust settling on the lenses.

This image revealing the north polar region of the Jovian moon Io was taken on October 15 by NASA’s Juno. Three of the mountain peaks visible in the upper part of image, near the day-night dividing line, were observed here for the first time by the spacecraft’s JunoCam.Image data: NASA/JPL-Caltech/SwRI/MSSS, Image processing by Ted Stryk The orbiter has performed 56 flybys of Jupiter and documented close encounters with three of the gas giant’s four largest moons. NASA’s Juno spacecraft will on Tuesday, Dec. 30, make the closest flyby of Jupiter’s moon Io that any spacecraft has made in over 20 years. Coming within roughly 930 miles (1,500 kilometers) from the surface of the most volcanic world in our solar system, the pass is expected to allow Juno instruments to generate a firehose of data. “By combining data from this flyby with our previous observations, the Juno science team is studying how Io’s volcanoes vary,” said Juno’s principal investigator, Scott Bolton of the Southwest Research Institute in San Antonio, Texas. “We are looking for how often they erupt, how bright and hot they are, how the shape of the lava flow changes, and how Io’s activity is connected to the flow of charged particles in Jupiter’s magnetosphere.” A second ultra-close flyby of Io is scheduled for Feb. 3, 2024, in which Juno will again come within about 930 miles (1,500 kilometers) of the surface. The spacecraft has been monitoring Io’s volcanic activity from distances ranging from about 6,830 miles (11,000 kilometers) to over 62,100 miles (100,000 kilometers), and has provided the first views of the moon’s north and south poles. The spacecraft has also performed close flybys of Jupiter’s icy moons Ganymede and Europa. This JunoCam image of Jupiter’s moon Io captures a plume of material ejected from the (unseen) volcano Prometheus. Indicated by the red arrow, the plume is just visible in the darkness below the terminator (the line dividing day and night). The image was taken by NASA’s Juno spacecraft on October 15.NASA/JPL-Caltech/SwRI/MSSS “With our pair of close flybys in December and February, Juno will investigate the source of Io’s massive volcanic activity, whether a magma ocean exists underneath its crust, and the importance of tidal forces from Jupiter, which are relentlessly squeezing this tortured moon,” said Bolton. Now in the third year of its extended mission to investigate the origin of Jupiter, the solar-powered spacecraft will also explore the ring system where some of the gas giant’s inner moons reside. Picture This All three cameras aboard Juno will be active during the Io flyby. The Jovian Infrared Auroral Mapper (JIRAM), which takes images in infrared, will be collecting the heat signatures emitted by volcanoes and calderas covering the moon’s surface. The mission’s Stellar Reference Unit (a navigational star camera that has also provided valuable science) will obtain the highest-resolution image of the surface to date. And the JunoCam imager will take visible-light color images. JunoCam was included on the spacecraft for the public’s engagement and was designed to operate for up to eight flybys of Jupiter. The upcoming flyby of Io will be Juno’s 57th orbit around Jupiter, where the spacecraft and cameras have endured one of the solar system’s most punishing radiation environments. “The cumulative effects of all that radiation has begun to show on JunoCam over the last few orbits,” said Ed Hirst, project manager of Juno at NASA’s Jet Propulsion Laboratory in Southern California. “Pictures from the last flyby show a reduction in the imager’s dynamic range and the appearance of ‘striping’ noise. Our engineering team has been working on solutions to alleviate the radiation damage and to keep the imager going.” More Io, Please After several months of study and assessment, the Juno team adjusted the spacecraft’s planned future trajectory to add seven new distant Io flybys (for a total of 18) to the extended mission plan. After the close Io pass on Feb. 3, the spacecraft will fly by Io every other orbit, with each orbit growing progressively more distant: The first will be at an altitude of about 10,250 miles (16,500 kilometers) above Io, and the last will be at about 71,450 miles (115,000 kilometers). The gravitational pull of Io on Juno during the Dec. 30 flyby will reduce the spacecraft’s orbit around Jupiter from 38 days to 35 days. Juno’s orbit will drop to 33 days after the Feb. 3 flyby. After that, Juno’s new trajectory will result in Jupiter blocking the Sun from the spacecraft for about five minutes at the time when the orbiter is at its closest to the planet, a period called perijove. Although this will be the first time the solar-powered spacecraft has encountered darkness since its flyby of Earth in October 2013, the duration will be too short to affect its overall operation. With the exception of the Feb. 3 perijove, the spacecraft will encounter solar eclipses like this during every close flyby of Jupiter from now on through the remainder of its extended mission, which ends in late 2025. Starting in April 2024, the spacecraft will carry out a series of occultation experiments that use Juno’s Gravity Science experiment to probe Jupiter’s upper atmospheric makeup, which provides key information on the planet’s shape and interior structure.

Research on the International Space Station is helping scientists to understand how fire spreads and behaves in different environments and learn how to prevent and extinguish fires in space. Combustion investigations contribute to the safety of crew members, equipment, and spacecraft by guiding selection of spacecraft cabin materials, improving understanding of fire growth, and identifying optimal fire suppression techniques. This research also contributes to fire safety on Earth and some studies improve our understanding of combustion for uses such as producing electricity and powering vehicles on the ground. Microgravity dramatically influences flames and provides a unique environment for studying combustion. For example, on Earth, hot gases from a flame rise and gravity pulls cooler, denser air to the bottom of a flame, creating the classic shape and flickering effect. In microgravity, this flow doesn’t occur and on the space station, low-momentum flames tend to be rounded or even spherical. By removing the effects of buoyancy, microgravity provides researchers a better understanding of specific flame behaviors. NASA astronaut Kate Rubins works on the space station’s Combustion Integrated Rack.NASA The Combustion Integrated Rack (CIR), developed and operated by NASA’s Glenn Research Center, provides a secure and safe environment for a wide range of combustion experiments. Different chamber inserts that enable a variety of investigations include the Multi-user Droplet Combustion Apparatus, which supported FLame Extinguishment Experiments (FLEX), the Advanced Combustion via Microgravity Experiments (ACME) insert, and the Solid Fuel Ignition and Extinction – Growth and Extinction Limit (SoFIE) chamber. FLEX, which analyzed the effectiveness of fire suppressants, led to the discovery of a type of cool flame, where the fuel continued “burning” under certain conditions after extinction of the visible flame. Typical flames produce carbon dioxide and water, but cool flames produce carbon monoxide and formaldehyde. Learning more about the behavior of these chemically different flames could lead to the development of more-efficient, less-polluting vehicles. Cool flames produced on Earth quickly flicker out. Since they burn longer in microgravity, scientists have the opportunity to study them. FLEX-2 looked at how quickly fuel droplets burn, the conditions required for soot to form, and how mixtures of liquid fuels evaporate before burning. Results could help make future spacecraft safer and increase fuel efficiency for engines using liquid fuel on Earth. ACME is a set of six independent studies using the CIR to examine fuel efficiency and pollutant production in combustion on Earth. The series also looked at improving spacecraft fire prevention through a better understanding of materials flammability. One ACME investigation, Flame Design, studied the quantity of soot produced under different flame conditions. Soot, the carbon residue left when carbon-containing material does not fully burn, causes environmental and health issues but is desirable for some purposes. Results could enable the design of flames with more or less soot, depending on the specific need, and may help create more efficient and less polluting designs for burning fuel. ACME’s Burning Rate Emulator (BRE) simulated the flammability of solid and liquid materials by burning gaseous fuels under specific conditions. Analysis of 59 BRE burn tests provided data on heat flow, flame size, effects of fuel mixture flow, and other important parameters.1 Results could improve the fundamental understanding of materials flammability and assess whether existing methods for testing flammability are effective in microgravity. Image of a flame burning one of the BASS tests on extinguishing burning fuels.NASA Burning and Suppression of Solids (BASS) was one of the first investigations to examine how to extinguish fuels burning in microgravity. Putting out fires in space must consider flame geometry, characteristics of the materials, and methods used to extinguish it, because methods used on the ground could be ineffective or even make the flame worse. BASS-II examined the characteristics of a variety of fuel samples to see whether materials burn as well in microgravity as in normal gravity, given the right conditions. Several papers have reported results from BASS-II, with findings including the differences between flame spread and fuel regression and comparison of flame spread rates.2,3 ESA (European Space Agency) astronaut Samantha Cristoforetti works on the SoFIE-GEL investigation of materials flammability.NASA SoFIE-GEL analyzes how the temperature of a fuel affects material flammability. Researchers report that experiment observations agree with trends predicted by the models. This investigation, the first in a series, tested various fuels including flat sheets, thick slabs, cylinders, and spheres. Saffire is a series of experiments conducted aboard uncrewed Cygnus cargo spacecraft after they depart the station, which makes it possible to test larger fires without putting crew members at risk. Results on flame spread in microgravity can be used to establish the rate of heat release in a spacecraft4 and show that reducing pressure slows down that spread.5 A sample of fabric burns inside an uncrewed Cygnus cargo spacecraft for the Saffire-IV experiment. NASA Confined Combustion, sponsored by the ISS National Lab, examines flame spread in confined spaces of different shapes. Confinement affects fire characteristics and hazards. Researchers report specifics on interactions between a flame and its surrounding walls and the fate of the flame, such as growth or extinction.6 These results provide guidance for the design of structures, fire safety codes, and response in space and on Earth. Other results suggest that confinement can increase or decrease solid fuel flammability depending on conditions.7 FLARE, an investigation sponsored by JAXA (Japan Aerospace Exploration Agency), also tests the flammability of materials in microgravity. Results could significantly improve fire safety on future missions. JAXA astronaut Satoshi Furukawa sets up hardware for the FLARE investigation. NASA Flame studies help keep crews in space safe. This research also could lead to more efficient combustion that reduces pollutants and produces more efficient flames for uses on Earth such as heating and transportation.

The telescope captured new images of Uranus, revealing detailed features of the planet’s rings and seasonal north polar cap, as well as bright storms near and below the southern border of the cap. This Webb image also shows 14 of the planet’s 27 moons: Oberon, Titania, Umbriel, Juliet, Perdita, Rosalind, Puck, Belinda, Desdemona, Cressida, Ariel, Miranda, Bianca, and Portia. Webb’s extreme sensitivity also picks up a smattering of background galaxies—most appear as orange smudges, and there are two larger, fuzzy white galaxies to the right of the planet in this field of view.

Ultra-High-Definition Video Beamed From Deep Space on This Week @NASA – December 22, 2023

The radio antennas of the NASA’s Canberra Deep Space Communications Complex are located near the Australian capital. It’s one of three Deep Space Network complexes around the world that keep the agency in contact with over 40 space missions. The DSN marks its 60th anniversary in December 2023.NASA/JPL-Caltech A single radio antenna dish stands alone at the Deep Space Network’s Canberra complex in this photo from 1969, six years after the DSN was founded. Canberra now consists of three 34-meter (112-foot) antennas and one 70-meter (230-foot) antenna.NASA/JPL-Caltech The agency’s DSN provides critical communications and navigation services to dozens of space missions, and it’s being modernized to support dozens more. NASA’s Deep Space Network marks its 60th year on Dec. 24. In continuous operations since 1963, the DSN is what makes it possible for NASA to communicate with spacecraft at or beyond the Moon. The dazzling galactic images captured by the James Webb Space Telescope, the cutting-edge science data being sent back from Mars by the Perseverance rover, and the historic images sent from the far side of the Moon by Artemis I – they all reached Earth via the network’s giant radio dish antennas. During 2024, these and other historic contributions from the past 60 years will be celebrated by NASA’s Space Communications and Navigation (SCaN) program, which manages and directs the ground-based facilities and services that the DSN provides. More than 40 missions depend on the network, which is expected to support twice that number in the coming years. That’s why NASA is looking to the future by expanding and modernizing this critical global infrastructure with new dishes, new technologies, and new approaches. “The DSN is the heart of NASA – it has the vital job of keeping the data flowing between Earth and space,” said Philip Baldwin, acting director of the network services division for SCaN at NASA Headquarters in Washington. “But to support our growing portfolio of robotic missions, and now the human Artemis missions to the Moon, we need to push forward with the next phase of DSN modernization.” Meeting Added Demands Managed by NASA’s Jet Propulsion Laboratory in Southern California for SCaN, the DSN allows missions to track, send commands to, and receive scientific data from faraway spacecraft. To ensure those spacecraft can always connect with Earth, the DSN’s 14 antennas are divided between three complexes spaced equally around the world – in Goldstone, California; Canberra, Australia; and Madrid, Spain. The Deep Space Network is much more than a deep space messaging service. Learn more about how the DSN carries out radio and gravity science experiments throughout the solar system.

For more efficiency, NASA has also changed how the network is operated: With a protocol called “Follow the Sun,” each complex takes turns running the entire network during their day shift and then hands off control to the next complex at the end of the day in that region – essentially, a global relay race that takes place every 24 hours. The cost savings, in turn, help fund DSN enhancements. At the same time, NASA has been busy making improvements to increase capacity, from upgrading and adding dishes to developing new technologies that will help support more spacecraft and dramatically increase the amount of data that can be delivered. One such technology is laser, or optical, communications, which could enable more data to be packed into transmissions. “Laser communications could transform how NASA communicates with faraway space missions,” said Amy Smith, deputy project manager for the DSN at JPL. After successfully testing the technique in Earth orbit and out to the Moon, NASA is currently using the DSOC (Deep Space Optical Communications) technology demonstration to test laser communications from ever-greater distances. Riding aboard the agency’s Psyche mission, DSOC has already sent video via laser to Earth from 19 million miles (31 million kilometers) away and aims to prove that high-bandwidth data can be sent from as far away as Mars. “NASA is proving that laser communication is viable, so now we are looking at ways to build optical terminals inside the existing radio antennas,” said Smith. “These hybrid antennas will be able to still transmit and receive radio frequencies but will also support optical frequencies.” See the missions the DSN is communicating with now Technological Heritage New technology is something that NASA and the DSN have embraced from their inception. The network’s roots extend to 1958, when JPL was contracted by the U.S. Army to deploy portable radio tracking stations to receive telemetry of the first successful U.S. satellite, Explorer 1, which JPL built. A few days after Explorer 1’s launch, but before the creation of NASA later that year, JPL was tasked with figuring out what would be needed to create an unprecedented telecommunications network to support future deep space missions, beginning with the early Pioneer missions. After NASA formed in 1958, JPL’s ground stations were named Deep Space Information Facilities, and they operated largely independently from one another until 1963. That’s when the DSN was officially founded and the ground stations were connected to JPL’s new network control center, which was nearing completion. Called the Space Flight Operations Facility, that building remains the “Center of the Universe” through which data from the DSN’s three global complexes flows. “We have six decades driving technological innovation, supporting hundreds of missions that have made countless discoveries about our planet and the universe it inhabits,” said Bradford Arnold, deputy director for the Interplanetary Network at JPL. “Our amazing workforce that continues to drive that innovation today forms a steadfast foundation upon which we can build the next 60 years of space exploration and scientific advancement.” For more information about the DSN, visit: https://www.nasa.gov/communicating-with-missions/dsn/ News Media Contact Ian J.
