NASA’s EMIT produced its first global maps of hematite, goethite, and kaolinite in Earth’s dry regions using data from the year ending November 2023. The mission collected billions of measurements of the three minerals and seven others that may affect climate when lofted into the air as dust storms.NASA/JPL-Caltech EMIT delivers first-of-a-kind maps of minerals in Earth’s dust-source areas, enabling scientists to model the fine particles’ role in climate change and more. NASA’s EMIT mission has created the first comprehensive maps of the world’s mineral dust-source regions, providing precise locations of 10 key minerals based on how they reflect and absorb light. When winds loft these substances into the air, they either cool or warm the atmosphere and Earth’s surface, depending on their composition. Understanding their abundance around the globe will help researchers predict future climate impacts. Launched to the International Space Station in 2022, EMIT – short for Earth Surface Mineral Dust Source Investigation – is an imaging spectrometer developed by NASA’s Jet Propulsion Laboratory in Southern California. The mission fills a crucial need among climate scientists for more detailed information on surface mineral composition. Surveying Earth’s surface from about 250 miles (410 kilometers) above, EMIT scans broad areas that would be impossible for a geologist on the ground or instruments carried by aircraft to survey, yet it does this while achieving effectively the same level of detail. EMIT, a NASA mission launched to the International Space Station in 2022, mapped hematite, goethite, and kaolinite in North Africa and the Arabian Peninsula. The three minerals are among 10 key substances the mission studied that are thought to influence climate change.NASA/JPL-Caltech To date, the mission has captured more than 55,000 “scenes” – 50-by-50-mile (80-by-80-kilometer) images of the surface – in its study area, which includes arid regions within a 6,900-mile-wide (11,000-kilometer-wide) belt around Earth’s mid-section. Taken together, the scenes comprise billions of measurements – more than enough to create detailed maps of surface composition. The mission has also demonstrated a range of additional capabilities in its 17 months in orbit, including detecting plumes of methane and carbon dioxide being emitted by landfills, oil facilities, and other infrastructure. “Wherever we need chemistry to understand something on the surface, we can do that with imaging spectroscopy,” said Roger Clark, an EMIT science team member and senior scientist at the Planetary Science Institute in Tucson, Arizona. “Now, with EMIT, we’re going to see the big picture, and that’s certainly going to open some eyes.” Dust and Climate Scientists have long known that airborne mineral dust affects the climate. They know that darker, iron oxide-rich substances absorb the Sun’s energy and warm the surrounding air, while non-iron-based, brighter substances reflect light and heat, cooling the air. Whether those effects have a net warming or cooling impact, however, has remained uncertain. Researchers have an idea of how dust travels through the atmosphere, but the missing piece has been the composition – the color, essentially – of the surface in the places dust typically originates, which until now was derived from fewer than 5,000 sample sites around the world. Based on billions of samples, EMIT’s maps offer much more detail. “We’ll take the new maps and put them into our climate models,” said Natalie Mahowald, EMIT’s deputy principal investigator and an Earth system scientist at Cornell University in Ithaca, New York. “And from that, we’ll know what fraction of aerosols are absorbing heat versus reflecting to a much greater extent than we have known in the past.” Dust and Ecosystems Beyond harnessing EMIT’s mineral data to improve Earth climate modeling, scientists can use the information to study dust’s impact on the ecosystems where it lands. There’s strong evidence that particles settling in the ocean can spur phytoplankton blooms, which can have implications for aquatic ecosystems and the planet’s carbon cycle. Scientists also have shown that dust originating in the Andes of South America, as well as in parts of northern and sub-Saharan Africa, provides nutrients for rainforest growth in the Amazon basin. EMIT data can enable researchers to pinpoint the sources of mineral dust and get a more detailed look at its composition, helping estimate the travel of key elements such as phosphorus, calcium, and potassium, which are thought to factor into this long-distance fertilization. “EMIT could help us to build more intricate and finely resolved dust-transport models to track the movement of those nutrients across long distances,” said Eric Slessarev, a soil researcher at Yale University in New Haven, Connecticut. “That will help us to better understand the chemistry of soils in places very far from the dust-generating regions.” A New Generation of Science Aside from tracking 10 key minerals that are part of its primary mission, EMIT data is being used to identify a range of other minerals, types of vegetation, snow and ice, and even human-produced substances at or near Earth’s surface. And with vastly more measurements at their disposal, researchers will be able to find statistical relationships between surface characteristics and other features of interest. For example, they might spot signals in EMIT data that correspond with the presence of rare-earth elements and lithium-bearing minerals, said Robert Green, a senior research scientist at JPL and EMIT’s principal investigator. This new information could be used to look for those substances in previously unknown places. “To this point we simply haven’t known the distribution of surface minerals over huge swaths of the planet,” said Phil Brodrick, a JPL data scientist who spearheaded the creation of the mineral maps. With the EMIT data, “there will likely be a new generation of science that comes out that we don’t know about yet, and that’s a really cool thing.” More About the Mission EMIT was selected from the Earth Venture Instrument-4 solicitation under the Earth Science Division of NASA’s Science Mission Directorate and was developed at NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech in Pasadena, California. The instrument’s data is available at the NASA Land Processes Distributed Active Archive Center for use by other researchers and the public.

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) In December 2022, NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) mission observed the dramatic and unexpected “disappearance” of a stream of charged particles constantly emanating off the Sun, known as the solar wind. This was caused by a special type of solar event that was so powerful, it created a void in its wake as it traveled through the solar system. Learn about the “disappearance” of the solar wind at Mars that was witnessed by MAVEN – an event last seen nearly a quarter-century ago at Earth. Credit: NASA’s Goddard Space Flight Center Download high-resolution video and images from NASA’s Scientific Visualization Studio. Due to this event, MAVEN’s measurements at Mars showed that the number of particles making up the solar wind dropped significantly. Without the pressure of the solar wind, the Martian atmosphere and magnetosphere expanded by thousands of kilometers. MAVEN is the only asset currently at Mars able to simultaneously observe both the Sun’s activity and the response of the Martian atmosphere to these solar influences. “When we first saw the data, and how dramatic the drop in the solar wind was, it was almost unbelievable,” said Jasper Halekas, professor at the University of Iowa and the lead author on a new study on the event. “We formed a working group to study the event, and we have found this time period to be rich with incredible findings.” Mars, like all the planets in our solar system, is constantly immersed in the solar wind. The solar wind exerts pressure on the Martian magnetosphere and ionosphere, and drives much of the escape of the atmosphere. The solar event in December 2022 was caused by faster-moving solar wind that overtook slower moving solar wind, which acted like a broom, sweeping and compressing the two regions together. This interaction, called a stream interaction region, left behind a rare void of extremely low-density solar wind in its wake, which was observed by MAVEN. This “disappearance” of the solar wind led to some incredible interactions within Mars’ magnetosphere and ionosphere. As the density of the solar wind dropped by a factor of 100, it caused the pressure to decrease and the magnetosphere and ionosphere of the planet were able to expand by thousands of kilometers­—more than tripled the typical size—and dramatically changed in character. The Sun’s magnetic field that typically is embedded within the Martian ionosphere was pushed outwards, which transformed the ionosphere from a magnetized to unmagnetized state. At the same time, the layer between the solar wind and the magnetosphere became unusually electromagnetically quiet. MAVEN’s observations of this dramatic event and subsequent transformation and expansion of the whole system is important to better understand the physics that drive atmospheric and water loss at Mars. “We are really getting to see how Mars responds when the solar wind is effectively removed,” Halekas added. “It makes for a great outlier study on what Mars would be like if it were orbiting a less ‘windy’ star.” Disappearing solar wind events on this scale are extremely rare and are produced at a time of increasing solar activity, so this was the first time the MAVEN mission had the opportunity to observe such a phenomenon. While other spacecraft at Mars and Earth also observed aspects of this event, only MAVEN was able to simultaneously take measurements from both the Sun and the Martian atmosphere’s response to it. “Observing extreme conditions is always scientifically invaluable,” said Shannon Curry, principal investigator for MAVEN at the University of California, Berkeley. “MAVEN was designed to observe these types of interactions between the Sun and the Martian atmosphere, and the spacecraft provided exceptional data during this truly anomalous solar event.” As the Sun moves toward solar maximum, the peak of its 11-year activity cycle, the MAVEN mission could have an even bigger impact on our understanding of extreme solar events. “This really shows the cross-divisional role that MAVEN plays at Mars,” said Gina DiBraccio, MAVEN deputy principal investigator and deputy director of the Heliophysics Science Division at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “MAVEN is not only observing the dynamics of the Martian atmosphere, it is also monitoring solar inputs to enhance our understanding of the Sun.” The study is being presented at the American Geophysical Union Fall Meeting in San Francisco. MAVEN’s principal investigator is based at the University of California, Berkeley, while NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the MAVEN mission. Lockheed Martin Space built the spacecraft and is responsible for mission operations. NASA’s Jet Propulsion Laboratory in Southern California provides navigation and Deep Space Network support. The Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder is responsible for managing science operations and public outreach and communications.

“I was on console as a part of the primary launch team [for Artemis I]. I was the Orion system specialist for Guidance, Navigation, and Control. … In a few missions, we’re sending astronauts to the Moon again, so being a part of the very, very first mission [was memorable]. … I wasn’t here in 2017 when they first began discussions, but [I can’t even explain how it felt] that within just the four-year journey, I could see how far we had come: from when we were talking about getting the hardware here, to the hardware arriving, and then [to realize] ‘Oh, it’s going today, we’re going!’ “… From a personal standpoint, I’m a person of faith, so for me, it was like: We launched at night — it was in the darkest part of the [night]. … Once the rocket launched, [I saw] how it illuminated such a dark space. So even when you’re in a dark space, you can let your light shine. And it won’t just shine for you and those that are immediately around you, but even people that you don’t know will notice it, even people that you will never see will notice your light shining and be inspired.” — Ales-Cia Winsley, Lead Space Launch System Avionics Engineer, NASA’s Kennedy Space Center Image Credit: NASA / Cory S Huston Interviewer: NASA / Michelle Zajac Check out some of our other Faces of NASA.

Those condensation trails can trap heat in our atmosphere under specific conditions and increase the impact the aviation industry has on global warming. NASA partnered with the Boeing ecoDemonstrator Explorer Program and others including General Electric Aerospace, the Federal Aviation Administration, the German Aerospace Center, United Airlines, and World Energy. Their goal was to see if sustainable aviation fuels and advanced engine technology can decrease contrail formation. Rich Moore, NASA’s principal investigator for ecoDemonstrator, watches the livestream of footage from a camera located under the belly of the DC-8 on Oct. 10. The contrails from the Boeing plane are visible on his laptop monitor.NASA / Jim Ross In October, NASA Armstrong Flight Research Center’s DC-8 aircraft flew behind a Boeing ecoDemonstrator Explorer, a 737-10 passenger jet that the company plans to turn over to United Airlines, to capture and measure its emissions. Scientists outfitted the DC-8 with instruments to collect data that will compare the emissions from sustainable aviation fuel to the emissions from conventional jet fuel. In its fifth decade of flying science missions, the DC-8 is the largest flying science laboratory in the world and served as an ideal platform for experts from the Advanced Air Transport Technology project in NASA’s Advanced Air Vehicles Program, and other scientific partners. Innovative technologies like sustainable aviation fuel and more efficient engine designs require state-of-the-art test models and exhaustive research methods performed by the most qualified experts in the world. That is what the ecoDemonstrator Explorer Program as a collaboration provided. Results from this collaborative study will be publicly available within a year to help the aviation sector improve its environmental impact worldwide.

6 Min Read NASA’s Webb Stuns With New High-Definition Look at Exploded Star NASA’s James Webb Space Telescope’s new view of Cassiopeia A (Cas A) Credits: NASA, ESA, CSA, STScI, D. Milisavljevic (Purdue University), T. Temim (Princeton University), I. De Looze (University of Gent) Mysterious features hide in near-infrared light Like a shiny, round ornament ready to be placed in the perfect spot on a holiday tree, supernova remnant Cassiopeia A (Cas A) gleams in a new image from NASA’s James Webb Space Telescope. As part of the 2023 Holidays at the White House, First Lady of the United States Dr. Jill Biden debuted the first-ever White House Advent Calendar. To showcase the “Magic, Wonder, and Joy” of the holiday season, Dr. Biden and NASA are celebrating with this new image from Webb. While all is bright, this scene is no proverbial silent night. Webb’s NIRCam (Near-Infrared Camera) view of Cas A displays this stellar explosion at a resolution previously unreachable at these wavelengths. This high-resolution look unveils intricate details of the expanding shell of material slamming into the gas shed by the star before it exploded. Cas A is one of the most well-studied supernova remnants in all of the cosmos. Over the years, ground-based and space-based observatories, including NASA’s Chandra X-Ray Observatory, Hubble Space Telescope, and retired Spitzer Space Telescope have assembled a multiwavelength picture of the object’s remnant. However, astronomers have now entered a new era in the study of Cas A. In April 2023, Webb’s MIRI (Mid-Infrared Instrument) started this chapter, revealing new and unexpected features within the inner shell of the supernova remnant. Many of those features are invisible in the new NIRCam image, and astronomers are investigating why. Image: Cassiopeia A (NIRCam) NASA’s James Webb Space Telescope’s new view of Cassiopeia A (Cas A) in near-infrared light is giving astronomers hints at the dynamical processes occurring within the supernova remnant. Tiny clumps represented in bright pink and orange make up the supernova’s inner shell, and are comprised of sulfur, oxygen, argon, and neon from the star itself. A large, striated blob at the bottom right corner of the image, nicknamed Baby Cas A, is one of the few light echoes visible NIRCam’s field of view. In this image, red, green, and blue were assigned to Webb’s NIRCam data at 4.4, 3.56, and 1.62 microns (F444W, F356W, and F162M, respectively). NASA, ESA, CSA, STScI, D. Milisavljevic (Purdue University), T. Temim (Princeton University), I. De Looze (University of Gent) ‘Like Shards of Glass’ Infrared light is invisible to our eyes, so image processors and scientists translate these wavelengths of light to visible colors. In this newest image of Cas A, colors were assigned to different filters from NIRCam, and each of those colors hints at different activity occurring within the object. At first glance, the NIRCam image may appear less colorful than the MIRI image. However, this simply comes down to the wavelengths in which the material from the object is emitting its light. The most noticeable colors in Webb’s newest image are clumps represented in bright orange and light pink that make up the inner shell of the supernova remnant. Webb’s razor-sharp view can detect the tiniest knots of gas, comprised of sulfur, oxygen, argon, and neon from the star itself. Embedded in this gas is a mixture of dust and molecules, which will eventually become components of new stars and planetary systems. Some filaments of debris are too tiny to be resolved by even Webb, meaning they are comparable to or less than 10 billion miles across (around 100 astronomical units). In comparison, the entirety of Cas A spans 10 light-years across, or 60 trillion miles. “With NIRCam’s resolution, we can now see how the dying star absolutely shattered when it exploded, leaving filaments akin to tiny shards of glass behind,” said Danny Milisavljevic of Purdue University, who leads the research team. “It’s really unbelievable after all these years studying Cas A to now resolve those details, which are providing us with transformational insight into how this star exploded.” Image: Cassiopeia A NIRCam/MIRI This image provides a side-by-side comparison of supernova remnant Cassiopeia A (Cas A) as captured by NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument). Objects in space reveal different aspects of their composition and behavior at different wavelengths. The outskirts of Cas A’s main inner shell, which appeared as a deep orange and red in the MIRI image, look like smoke from a campfire in the NIRCam image. The dust in the circumstellar material being slammed into by the shockwave is too cool to be detected directly at near-infrared wavelengths, but lights up in the mid-infrared. Also not seen in the near-infrared view is the loop of green light in the central cavity of Cas A that glows in mid-infrared, nicknamed the Green Monster by the research team. NASA, ESA, CSA, STScI, D. Milisavljevic (Purdue University), T. Temim (Princeton University), I. De Looze (University of Gent) Hidden Green Monster When comparing Webb’s new near-infrared view of Cas A with the mid-infrared view, its inner cavity and outermost shell are curiously devoid of color. The outskirts of the main inner shell, which appeared as a deep orange and red in the MIRI image, now look like smoke from a campfire. This marks where the supernova blast wave is ramming into surrounding circumstellar material. The dust in the circumstellar material is too cool to be detected directly at near-infrared wavelengths, but lights up in the mid-infrared. Researchers say the white color is light from synchrotron radiation, which is emitted across the electromagnetic spectrum, including the near-infrared. It’s generated by charged particles traveling at extremely high speeds spiraling around magnetic field lines. Synchrotron radiation is also visible in the bubble-like shells in the lower half of the inner cavity. Also not seen in the near-infrared view is the loop of green light in the central cavity of Cas A that glowed in mid-infrared, nicknamed the Green Monster by the research team. This feature was described as “challenging to understand” by researchers at the time of their first look. While the ‘green’ of the Green Monster is not visible in NIRCam, what’s left over in the near-infrared in that region can provide insight into the mysterious feature. The circular holes visible in the MIRI image are faintly outlined in white and purple emission in the NIRCam image – this represents ionized gas. Researchers believe this is due to the supernova debris pushing through and sculpting gas left behind by the star before it exploded. Image: Cassiopeia A Features This image highlights several interesting features of supernova remnant Cassiopeia A as seen with Webb’s NIRCam (Near-Infrared Camera): NIRCam’s exquisite resolution is able to detect tiny knots of gas, comprised of sulfur, oxygen, argon, and neon from the star itself; Circular holes visible in the MIRI image within the Green Monster are faintly outlined in white and purple emission in the NIRCam image; An example of a light echo – when light from the star’s long-ago explosion has reached, and is warming, distant dust, which is glowing as it cools down; A particularly intricate and large light echo, nicknamed Baby Cas A by researchers. NASA, ESA, CSA, STScI, D. Milisavljevic (Purdue University), T. Temim (Princeton University), I. De Looze (University of Gent). Baby Cas A Researchers were also absolutely stunned by one fascinating feature at the bottom right corner of NIRCam’s field of view. They’re calling that large, striated blob Baby Cas A – because it appears like an offspring of the main supernova. This is a light echo, where light from the star’s long-ago explosion has reached and is warming distant dust, which is glowing as it cools down. The intricacy of the dust pattern, and Baby Cas A’s apparent proximity to Cas A itself, are particularly intriguing to researchers. In actuality, Baby Cas A is located about 170 light-years behind the supernova remnant. There are also several other, smaller light echoes scattered throughout Webb’s new portrait. The Cas A supernova remnant is located 11,000 light-years away in the constellation Cassiopeia. It’s estimated to have exploded about 340 years ago from our point of view. The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

The First Images From Our Psyche Spacecraft on This Week @NASA – December 8, 2023

Oakwood School’s Team Pink won first place in the Invention Challenge at NASA’s Jet Propulsion Laboratory. Paul MacNeal (left) has run the competition since 1998.NASA/JPL-Caltech The homemade devices built by competing teams relied on catapults, crossbows, small motors, and more to accomplish seven consecutive steps to sink a crumpled piece of paper into a wastebasket.NASA/JPL-Caltech To compete in a race against the clock and each other, 18 student teams built complicated contraptions for the annual Invention Challenge at NASA’s Jet Propulsion Laboratory. Some 250 students hauled homemade machines they’d spent weeks honing to NASA’s Jet Propulsion Laboratory in Southern California on Friday, Dec. 8, for the 24th annual JPL Invention Challenge. The rules for the creative engineering competition change every year, but the overall goal is the same: Build a device capable of accomplishing a specified task within 60 seconds. This year, teams needed to come up with machines that could accomplish seven consecutive steps, ultimately dropping a crumpled piece of paper in a wastebasket. Students employed trebuchet catapults, crossbows, small motors, and “things with a bit of oomph,” said mechanical systems engineer Paul MacNeal, who has been organizing the competition since it began in 1998. “The Mouse Trap game from when I was a little kid is what it’s patterned after,” MacNeal said, referring to the board game in which players would construct elaborate traps for each other’s plastic rodents. “It was such a tough competition this year. It’s almost like unfolding the James Webb Space Telescope: Every action has to go right.” JPL’s Paul MacNeal started the Invention Challenge so that students could experience the fun of hands-on engineering and of STEM learning while developing team-building skills.NASA/JPL-Caltech And in this competition, fast. Every team that completed the task did so in under five seconds. Team Pink, the winning student team from Oakwood High School in North Hollywood, California, sank its paper ball in the basket in just 1.25 seconds, using a launcher at the start to knock over a series of five dominoes. The last domino hit a switch that turned on a conveyor belt to push the paper ball into the basket. “I was a little nervous at the beginning,” said Team Pink member and Oakwood High senior Midori Bonner. “There are a lot of good teams that were going really fast, but we’ve been training so hard for almost four months, I had faith in our team and the work we had put in.” Team Roman Bridge from Los Angeles Senior High School and Team Green from Oakwood High School took second and third place, respectively. Eighteen of the student teams competing in Friday’s finals had survived two regional events in November involving 40 school teams from Los Angeles and Orange counties. Four JPL-sponsored teams of professional engineers separately battled it out. Having professional engineers compete is part of MacNeal’s larger goal of inspiring students: He started the free competition so that they could experience the fun of hands-on engineering and of STEM learning while developing team-building skills along the way. He provides participants with nothing but the rules; teams have to figure out the rest themselves. “Even if they don’t do well, they worked hard to get where they were,” MacNeal said. “It’s just satisfying to see all the inventions they come up with.” News Media Contact Melissa Pamer Jet Propulsion Laboratory, Pasadena, Calif. 626-314-4928 melissa.pamer@jpl.nasa.gov 2023-179 View the full article

Engineers and technicians process the right forward center segment of the Space Launch System solid rocket boosters for the Artemis II mission inside the Rotation, Processing and Surge Facility (RPSF) at NASA’s Kennedy Space Center in Florida on Tuesday, Nov. 27, 2023. Inside the Rotation, Processing and Surge Facility at NASA’s Kennedy Space Center in Florida, engineers and technicians process the right forward center segment of the SLS (Space Launch System) rocket on Nov. 28, 2023. The ongoing processing of the segments is the first step before stacking operations begin and the segments will form the twin solid rocket boosters for the SLS rocket that will power NASA’s Artemis II mission. After arriving via rail in September, the team has been inspecting each segment one-by-one and lifting them to a vertical position to ensure the solid propellant and segment are ready for integration and launch. Engineers and technicians process and inspect the propellant of the right forward center segment of the Space Launch System solid rocket boosters for the Artemis II mission inside the Rotation, Processing and Surge Facility (RPSF) at NASA’s Kennedy Space Center in Florida on Monday, Nov. 27, 2023. Once processing is complete for all 10 segments, they will be moved one at a time to the Vehicle Assembly Building for stacking atop the mobile launcher. Standing 17 stories tall and burning approximately six tons of propellant every second, each booster generates more thrust than 14 four-engine jumbo commercial airliners. Together, the twin boosters provide more than 75 percent of the total SLS thrust at launch. The Artemis II mission will send four astronauts around the Moon as part of the agency’s effort to establish a long-term science and exploration presence at the Moon, and eventually Mars.

Researchers with the BioSCape campaign collect vegetation data from the Cape of Good Hope in South Africa. The field work, which took place in October and November, was part of an international collaboration that could help inform the capabilities of future satellite missions aimed at studying plants and animals.Adam Wilson NASA satellite and airborne tools aid an international team studying biodiversity on land and in the water around South Africa. An international team of researchers spent October and November 2023 in the field studying one of the world’s most biologically diverse areas – South Africa’s Greater Cape Floristic Region. As part of the effort, researchers used NASA airborne and space-based instruments to gather complementary data to better understand the unique aquatic and terrestrial ecosystems in this region. Their findings will inform the capabilities of future satellite missions aimed at studying plants and animals. “The food we eat, the clean water that we drink, and the air we breathe comes from the diversity of life on planet Earth,” said Erin Hestir of the University of California, Merced, and the campaign’s lead aquatic researcher. “As we lose species, we’re potentially losing Earth’s ability to sustain healthy human societies and provide healthy food and clean water for all.” Known as the Biodiversity Survey of the Cape (BioSCape), the effort is a large collaboration led in the U.S. by NASA, the University at Buffalo in New York, and the University of California, Merced. It is led in South Africa by the University of Cape Town and the South African Environmental Observation Network. The Greater Cape Floristic Region, where the BioSCape field work took place, is outlined in dark green in this map of the southwestern tip of South Africa. The region is a biodiversity hotspot that includes environments dominated by a shrubland called fynbos.NASA Earth Observatory The Greater Cape Floristic Region covers about 2.5 million acres (1 million hectares) on South Africa’s southwestern tip. Home to many plant and animal species found nowhere else on Earth, the biodiversity hotspot is recognized as a World Heritage Site by the United Nations Educational, Scientific, and Cultural Organization (UNESCO). The area also includes several UNESCO Biosphere reserves to protect unique terrestrial and aquatic environments. The BioSCape team is testing how well airborne and satellite remote sensing can characterize the region’s terrestrial, freshwater, and marine biodiversity. Space- and airplane-based instruments can cover more ground – and do so faster as well as more frequently – than crews in the field. This has a wide range of practical applications, from mapping the presence of invasive plants to better understanding the drivers of harmful algal blooms. A Challenging Area “South Africa is a hugely biodiverse place, but it’s a very challenging environment in which to do remote sensing research,” said Anabelle Cardoso, BioSCape science team manager at the University at Buffalo and the University of Cape Town. “With so many plant and animal species packed into a relatively small area, using remote sensing instruments to differentiate between species living in close proximity can be difficult.” Three of the BioSCape aircraft sensors are imaging spectrometers, which observe different wavelengths of visible and infrared light reflected or emitted by various materials on Earth’s surface and in the atmosphere. Each material has its own spectral fingerprint, enabling researchers to tell what they are observing. A researcher attaches a sensor to a tree as part of the BioSCape campaign in the Greater Cape Floristic Region in South Africa.Adam Wilson Scientists collect biological samples from South Africa’s Walker Bay as part of the BioSCape campaign. The information from the samples will help to quantify the biodiversity of the bay.Otto Whitehead (Fishwater Films) For example, the dominant vegetation in the Greater Cape Floristic Region is a type of shrubland known as fynbos, which contains thousands of plant species. “We want to know whether the spectral signatures from these closely related fynbos variations are different enough that we can tell them apart in the data,” said Kerry Cawse-Nicholson, a research scientist at NASA’s Jet Propulsion Laboratory in Southern California. “The discrimination of the biodiversity of phytoplankton in coastal and inland waters with imaging spectrometer data would advance science on aquatic ecosystem dynamics,” said Liane Guild, a research scientist at NASA’s Ames Research Center in California’s Silicon Valley. It would do this by offering new insights on land-water interactions, including riverine plumes, runoff, sedimentation, and algae blooms in coastal and inland waters that could have impacts on food security. Remote sensing capabilities like these will be vital for future satellites, such as the Surface Biology and Geology mission being planned for NASA’s Earth System Observatory. A More Complete Picture BioSCape crews collected data on land and in the water, efforts that include conducting plant and animal surveys and taking environmental DNA samples. Their findings will both augment and help confirm species information gathered by four NASA airborne instruments and two of the agency’s space-based instruments. Mounted on airplanes, the Airborne Visible/Infrared Imaging Spectrometer – Next Generation, the Hyperspectral Thermal Emission Spectrometer, and the Portable Remote Imaging Spectrometer are managed by JPL. Their detection of spectral fingerprints ranges from the ultraviolet part of the spectrum through the visible and into the infrared. Combined, their data provides information to help differentiate species and study water quality in reservoirs, among other things. Managed by NASA’s Goddard Space Flight Center in Maryland, the fourth airborne instrument is the Land, Vegetation, and Ice Sensor, which uses laser technology, known as lidar, to construct a 3D representation of the land surface and vegetation. That data can provide information on the structure of vegetation – including tree and plant height and the internal layers of forests – as well as the ground topography beneath tree cover. This data will also help calibrate and inform current and future space-based lidars, such as the Global Ecosystem Dynamics Investigation currently operating on the International Space Station and a potential mission to study surface topography and vegetation. In addition, the BioSCape team is using observations from two JPL-managed instruments on the space station. NASA’s ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station measures land surface temperature and can be used to assess plant stress due to temperature or water availability. The imaging spectrometer EMIT, short for Earth Surface Mineral Dust Source Investigation, gathers data on surface minerals, among other things, lending insight into the geology of the Greater Cape Floristic Region. “One of the really exciting things is that when we combine the spectroscopy and the 3D structure, we can get a detailed biochemical and structural picture of the ecosystem,” said Adam Wilson of the University at Buffalo and one of the campaign’s lead researchers. This could help identify which plant species live in various environments, the presence of invasive plants, and how vegetation recovers after a wildfire. The data collected by BioSCape has the potential for wide-ranging research and applications, particularly for the people of South Africa. The project was designed in collaboration with several South African institutions, as well as national and provincial park systems, which plan to incorporate data and analyses from BioSCape into management of natural resources.

This quad-agency agreement will further research and operations of space weather to improve space weather predictions and preparedness while also mitigating its impacts. NOAA / Robert Hyatt On Dec. 7, 2023, Nicola Fox, associate administrator for NASA’s Science Mission Directorate, signed on behalf of the agency the Memorandum of Agreement for Space Weather Research-To-Operations-To-Research Collaboration. This quad-agency agreement is between NASA, the National Oceanic and Atmospheric Administration, the National Science Foundation, and the U.S. Air Force. The memorandum outlines the responsibilities for collaboration across the federal government to enhance the country’s preparedness for space weather – the environmental changes caused in space by the constant outflow of solar wind from the Sun. In addition to improving our ability to protect satellites and GPS signals from space weather, NASA’s heliophysics division works closely with our Artemis program to support the human exploration of deep space in a variety of ways including learning how to measure the radiation environment on and around the moon. These measurements will aid in the prediction and validation of the radiation environment that our astronauts will experience. View the full article

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The best known use of GPS satellites is to help people know their location whether driving a car, navigating a ship or plane, or trekking across remote territory. Another important, but lesser-known, use is to distribute information to other Earth-viewing satellites to help them pinpoint measurements of our planet. NASA and several other federal agencies, including the U.S. Space Force, U.S. Space Command, the U.S. Naval Research Laboratory, and the National Geospatial-Intelligence Agency are improving the location accuracy of these measurements down to the millimeter with a new set of laser retroreflector arrays, or LRAs. Reflection of the laser retroreflector array through the testing apparatus.NASA/Zach Denny “The primary benefit of laser ranging and LRAs is to improve the geolocation of all of our Earth observations,” said Stephen Merkowitz, project manager for NASA’s Space Geodesy Project at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. A team of scientists and engineers with the project tested these arrays earlier this year to ensure they were up to their task and they could withstand the harsh environment of space. Recently the first set of these new laser retroreflector arrays was shipped to the U.S. Space Force and Lockheed Martin in Littleton, Colorado, to be added to the next generation of GPS satellites. How do Laser Retroreflector Arrays Work? Laser retroreflector arrays make it possible to do laser ranging – using small bursts of laser light to detect distances between objects. Pulses of laser light from a ground station are directed toward an orbiting satellite, which then reflect off the array and return to the station. The time it takes for the light to travel from the ground to the satellite and back again can be used to calculate the distance between the satellite and the ground. Laser ranging and laser retroreflector arrays have been part of space missions for decades, and they are currently mounted on and essential to the operation of Earth-viewing satellites like ICESat-2 (Ice, Cloud, and land Elevation satellite 2), SWOT (Surface Water and Ocean Topography), and GRACE-FO (Gravity Recovery and Climate Experiment Follow On). LRAs for laser ranging were even deployed on the surface of the Moon during the Apollo missions. “The LRAs are special mirrors,” said Merkowitz. “They’re different from a normal mirror because they bounce back light directly towards its original source.” For laser ranging, scientists want to direct light beams back to the original source. They do this by placing three mirrors at right angles, essentially forming an inside corner of a cube. The laser retroreflector arrays are made up of an array of 48 of these mirrored corners. “When light enters the array, due to those 90-degree angles, the light will bounce and take a series of reflections, but the output angle will always come out at the same angle as the one that came in,” said Zach Denny, optical engineer for the Space Geodesy Project at Goddard. LRAs in testing at Goddard, captured by Zach Denny. The blue reflecting from the retroreflectors – which are 3.5 inches in diameter – are reflections of the gloves Denny was wearing while the black color is the reflection of his phone lens.NASA/Zach Denny What Will Laser Retroreflector Arrays Help? Geodesy is the study of Earth’s shape, as well as its gravity and rotation, and how they all change over time. Laser ranging to laser retroreflector arrays is a key technique in this study. The surface of Earth is constantly changing in small ways due to shifting tectonic plates, melting ice, and other natural phenomena. With these constant shifts – and the fact that Earth is not a perfect sphere – there must be a way to define the measurements on Earth’s surface. Scientists call this a reference frame. Not only do these arrays and laser ranging help to precisely locate the satellites in orbit, but they also provide accurate positioning information for the ground stations back on Earth. With this information, scientists can even go so far as to find the center of the mass of Earth, which is the origin, or zero point, of the reference frame. Geodetic measurements – laser ranging to reference satellites like LAGEOS (Laser Geodynamic Satellites) – are used to constantly determine the location of Earth’s center of mass down to a millimeter. These measurements are critical for enabling scientists to assign a longitude and latitude to satellite measurements and put them on a map. Significant events like tsunamis and earthquakes can cause small changes to the Earth’s center of mass. Scientists need accurate laser ranging measurements to quantify and understand those changes, said Linda Thomas, a research engineer at the U.S. Naval Research Laboratory in Washington. Satellite measurements of subtle but important Earth phenomena, such as sea level rise, rely on an accurate reference frame. The long-term global trend of sea level rise, as well as its seasonal and regional variations, occur at rates of just a few millimeters a year. The reference frame needs to be more accurate than such changes if scientists want to accurately measure them. “Geodesy is a fundamental part of our daily lives because it tells us where we are and it tells us how the world is changing,” said Frank Lemoine, project scientist for NASA’s Space Geodesy Project.

NASA’s Hubble Space Telescope can resolve individual stars in the densely-packed cores of globular clusters like NGC 2210.ESA/Hubble & NASA, A. Sarajedini This striking Hubble Space Telescope image shows the densely packed globular cluster known as NGC 2210, which is situated in the Large Magellanic Cloud (LMC). The LMC lies about 157,000 light-years from Earth and is a so-called satellite galaxy of the Milky Way, meaning that the two galaxies are gravitationally bound. Globular clusters are very stable, tightly bound clusters of thousands or even millions of stars. Their stability means that they can last a long time, and therefore globular clusters are often studied to investigate potentially very old stellar populations. In fact, 2017 research using some of the data that were also used to build this image revealed that a sample of LMC globular clusters were incredibly close in age to some of the oldest stellar clusters found in the Milky Way’s halo. They found that NGC 2210 specifically probably clocks in at around 11.6 billion years old. Even though this is only a couple of billion years younger than the universe itself, it made NGC 2210 by far the youngest globular cluster in their sample. All other LMC globular clusters studied in the same work were found to be even older, with four of them over 13 billion years old. This tells astronomers that the oldest globular clusters in the LMC formed contemporaneously with the oldest clusters in the Milky Way, even though the two galaxies formed independently. As well as being a source of interesting research, this old-but-relatively-young cluster is also extremely beautiful, with its highly concentrated population of stars. The night sky would look very different from the perspective of an inhabitant of a planet orbiting one of the stars in a globular cluster’s center: the sky would appear to be stuffed full of stars, in a stellar environment that is thousands of times more crowded than our own.

NASA’s Starling mission includes technologies that have received support from the University SmallSat Technology Partnerships program. Krystine Carrington of Axient-MEIS, Starling integration and testing engineer, prepares Starling spacecraft for testing at NASA’s Ames Research Center in California’s Silicon Valley ahead of the mission’s launch. NASA/Dominic Hart Eight U.S. university teams are partnering with NASA to advance technologies for small spacecraft, increasing their capability to support the agency’s science and exploration missions within the Earth, cislunar, and deep space domains. The University SmallSat Technology Partnerships (USTP) initiative within NASA’s Small Spacecraft Technology (SST) program selected the eight teams from proposals received in response to the program’s 2023 USTP solicitation. NASA is focused on enabling small missions to continue supporting sustained lunar presence, promoting next generation mission architectures for scientific discovery, and stimulating space commerce. At the present time, small spacecraft, or SmallSats, primarily operate in low Earth orbit. Through these collaborative partnerships, technology advancements will expand the potential of SmallSats as they extend their capabilities to more complex Earth, lunar, and deep space science and exploration missions. SmallSats are expected to support increasingly important and complex functions and through partnerships with industry and academia, their utility will continue to advance. Improvements in SmallSat capability will enable them to support and perform science and deep space exploration, provide space situational awareness and national security-oriented capabilities, and expand the range of services available to people on Earth for greater economic growth and societal benefit. The following university teams were selected by the USTP initiative to mature new systems and capabilities, with support from a NASA center of their choice. The projects focus on one of three technology topic areas listed below to enhance SmallSat potential.

3 min read Amateur Astronomers Help Discover Cosmic Crash NASA Volunteer Arttu Sainio saw the star Asassn-21qj brightening, possibly due to crashing planets. Credit: Dan Caselden, NASA Astronomers found what looks like a glowing cloud of dust from a massive planetary pile-up—and NASA volunteers helped make the discovery! A recent paper in Nature describes how an international group of professional and amateur astronomers teamed up to measure the heat glow of two ice giant planets colliding and see the resultant dust cloud moving in front of the parent star several years later. The story began back in 2021, when the All-Sky Automated Survey for Supernovae (ASAS-SN) network noticed that a Sun-like star 1800 light years away was rapidly fading. Some 30 days later, NASA volunteer Arttu Sainio was reading X (formerly Twitter), and caught professional astronomers Dr. Matthew Kenworthy and Dr. Eric Mamajek speculating about this weird event. Arttu decided to further investigate this star, called Asassn-21qj, on his own, using data from NASA’s NEOWISE mission. Arttu was surprised to find that the star had demonstrated an unexpected brightening in infrared light two years before the optical dimming event. So he joined the talk on social media and shared his finding with the two astronomers. “Out of the blue, amateur astronomer Arttu Sainio on social media pointed out that the star brightened up in the infrared over a thousand days before the optical fading,” said Kenworthy. “I knew then that this was an unusual event.” More contributions from amateurs helped determine the nature of the star. Amateur spectroscopist Hamish Barker tried to capture a spectrum of Asassn-21qj in late July, 2022. A spectrum spreads out the colors of the starlight, revealing the star’s temperature. However, the star turned out to be too dim, so Hamish asked Olivier Garde from a French amateur astronomy team if they could add ASASSN-21q to their target list. The team, called the Southern Spectroscopic project Observatory Team (or “2SPOT”), succeeded in collecting the needed spectrum in early September, 2022 and forwarded it Kenworthy. The 2SPOT team members are Stéphane Charbonnel, Pascal Le Dû, Olivier Garde, Lionel Mulato and Thomas Petit. Two more amateur astronomers also independently observed the star and contributed their data to the study. Amateur spectroscopist Sean Curry provided a spectrum of Asassn-21qj in early April, 2023. Dr. Franz-Josef (Josch) Hambsch followed the star from his remote observatory ROAD (Remote Observatory Atacama Desert). He submitted his results via the American Association of Variable Star Observers (AAVSO) database. Want to help find more objects like Asassn-21qj? Help the Disk Detective project search for more exotic clouds of dust around nearby stars—or try the Backyard Worlds: Planet 9 project, where Sainio learned some of his skills. “Thanks to working previously with Backyard Worlds, retrieving WISE timeline photometry from NASA’s infrared archive (IRSA) was a logical step for me,” said Sainio.

Polarization is a characteristic of light that can help reveal information about where that light came from, such as the geometry and inner workings of the ultra-powerful energy sources from which it emanates. A gif of IXPE deploying in space before starting its science operations to study the cosmos.NASA Launched Dec. 9, 2021, IXPE orbits Earth some 340 miles high, studying X-ray emissions from powerful cosmic phenomena thousands to billions of light-years from Earth, including quasars, blazars, remnants of supernova explosions such as neutron stars, and high-energy particle streams spewing from the vicinity of black holes at nearly the speed of light. “Adding X-ray polarization to our arsenal of radio, infrared, and optical polarization is a game changer,” said Alan Marscher, a Boston University astronomer who leads a research group that uses IXPE’s findings to analyze supermassive black holes. “We’re all familiar with X-rays as a diagnostic medical tool for humans. Here we’re using them in a different way, but they are again revealing information that is otherwise hidden from us,” said Stanford University researcher Josephine Wong, who co-authored findings in October based on IXPE studies of the pulsar wind nebula MSH 15-52, some 16,000 light-years from Earth. Martin Weisskopf, the astrophysicist who led the development of IXPE and served as its principal investigator until his retirement from NASA in spring 2022, agreed. There can be no question that IXPE has shown that X-ray polarimetry is important and relevant to furthering our understanding of how these fascinating X-ray systems work. Martin Weisskopf Retired IXPE Principal Investigator Scientists have long understood, for example, the fundamentals of blazars such as Markarian 501 and Markarian 421. A blazar is a massive black hole feeding off material swirling around it in a disk, creating powerful jets of high-speed cosmic particles which rush away in two directions perpendicular to the disk. But how are those particles accelerated to such high energies? IXPE data published in November 2022 in the journal Nature identified the culprit at Markarian 501 as a shock wave within the jet. This NASA illustration shows the structure of a black hole jet as inferred by recent IXPE observations of the blazar Markarian 421. The jet is powered by an accretion disk, shown at the bottom of the image, which orbits and falls into the black hole over time. Helical magnetic fields are threaded through the jet. IXPE observations have shown that the X-rays must be generated in a shock originating within material spiraling around the magnetic fields. The inset shows the shock front itself. X-rays are generated in the white region nearest the shock front, whereas optical and radio emission must originate from more turbulent regions further away from the shock.NASA/Pablo Garcia “This is a 40-year-old mystery that we’ve solved,” said Yannis Liodakis, a NASA Postdoctoral Program researcher at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “We finally had all of the pieces of the puzzle, and the picture they made was clear.” IXPE also conducted unprecedented studies of three supernova remnants – Cassiopeia A, Tycho, and SN 1006 – helping scientists further their understanding of the origin and processes of the magnetic fields surrounding these phenomena. IXPE is even shedding new light on fundamental mechanisms of our own galaxy. According to studies IXPE conducted in early 2022, Sagittarius A*, the supermassive black hole at the center of the Milky Way, woke up about 200 years ago to devour gas and other cosmic detritus, triggering an intense, short-lived X-ray flare. By combining data from IXPE, Chandra, and the European Space Agency’s XMM-Newton mission, researchers determined the event occurred around the start of the 19th century. “We know change can happen to active galaxies and supermassive black holes on a human timescale,” said IXPE project scientist Steve Ehlert at NASA Marshall. “IXPE is helping us better understand the timescale on which the black hole at the center of our galaxy is changing. We’re eager to observe it further to determine which changes are typical and which are unique.” This new image of supernova remnant SN 1006 combines data from IXPE and NASA’s Chandra X-ray Observatory. The red, green, and blue elements reflect low, medium, and high energy X-rays, respectively, as detected by Chandra. The IXPE data, which measure the polarization of the X-ray light, is show in purple in the upper left corner, with the addition of lines representing the outward movement of the remnant’s magnetic field.X-ray: NASA/CXC/SAO (Chandra); NASA/MSFC/Nanjing Univ./P. Zhou et al. (IXPE); IR: NASA/JPL/CalTech/Spitzer; Image Processing: NASA/CXC/SAO/J.Schmidt IXPE has also supported observations of unanticipated cosmic events – such as the brightest pulse of intense radiation ever recorded, which abruptly swept through our solar system in October 2022. The pulse stemmed from a powerful gamma-ray burst likely to occur no more than once in 10,000 years, researchers said. Backing up data from NASA’s Fermi Space Telescope and other imagers, IXPE helped determine how the powerful emission was organized and confirmed that Earth imagers viewed the jet almost directly head-on. Perhaps most exciting to space scientists is how IXPE data is upending conventional wisdom about various classes of high-energy sources. “So many of the polarized X-ray results we’ve seen over the past two years were a big surprise, tossing theoretical models right out the window,” Ehlert said. Seeing results we didn’t anticipate sparks new questions, new theories. It’s really exciting! Steve Ehlert IXPE Project Scientist That excitement continues to build among IXPE partners around the world. In June, the mission was formally extended for 20 months beyond its initial two-year flight, meaning IXPE will continue to observe high-energy X-ray emissions across the cosmos through at least September 2025. The new year also will mark the start of the IXPE General Observer Program, which invites astrophysicists and other space scientists around the world to propose and take part in studies using the IXPE telescope. Beginning in February 2024, as much as 80% of IXPE’s time will be made available to the broader scientific community.

2 min read Hubble Captures a Cluster in the Cloud NASA’s Hubble Space Telescope is powerful enough to resolve individual stars in the densely-packed cores of globular clusters like NGC 2210. ESA/Hubble & NASA, A. Sarajedini This striking Hubble Space Telescope image shows the densely packed globular cluster known as NGC 2210, which is situated in the Large Magellanic Cloud (LMC). The LMC lies about 157,000 light-years from Earth and is a so-called satellite galaxy of the Milky Way, meaning that the two galaxies are gravitationally bound. Globular clusters are very stable, tightly bound clusters of thousands or even millions of stars. Their stability means that they can last a long time, and therefore globular clusters are often studied to investigate potentially very old stellar populations. In fact, 2017 research using some of the data that were also used to build this image revealed that a sample of LMC globular clusters were incredibly close in age to some of the oldest stellar clusters found in the Milky Way’s halo. They found that NGC 2210 specifically probably clocks in at around 11.6 billion years old. Even though this is only a couple of billion years younger than the universe itself, it made NGC 2210 by far the youngest globular cluster in their sample. All other LMC globular clusters studied in the same work were found to be even older, with four of them over 13 billion years old. This tells astronomers that the oldest globular clusters in the LMC formed contemporaneously with the oldest clusters in the Milky Way, even though the two galaxies formed independently. As well as being a source of interesting research, this old-but-relatively-young cluster is also extremely beautiful, with its highly concentrated population of stars. The night sky would look very different from the perspective of an inhabitant of a planet orbiting one of the stars in a globular cluster’s center: the sky would appear to be stuffed full of stars, in a stellar environment that is thousands of times more crowded than our own.
