NASA’s Artemis II Moon Mission Research Continues on Earth

5 min read NASA’s Artemis II Moon Mission Research Continues on Earth Artemis II astronaut Victor Glover walks on a treadmill while in a space suit harnessed to NASA’s Active Response Gravity Offload System at NASA’s Johnson Space Center. Glover is simulating a walk on a planetary surface while in a suit that has been offloaded to lunar gravity. Artemis II astronauts completed this and other suited tasks before their mission launched and within a few days of landing, giving researchers a chance to assess how quickly upon landing crews’ bodies adapt to a different gravity. Results will help scientists better understand how soon after landing crews can complete mission-critical tasks on the surface of the Moon or Mars. NASA/Robert Markowitz Since NASA’s Artemis II crew members safely splashed down in the Pacific Ocean on April 10 after their record-setting mission around the Moon, science teams have been busy collecting more data and combing through observations collected on the test flight. Results from these science investigations will help support safe human exploration of deep space and provide a blueprint for how future missions will conduct science on the lunar surface as NASA builds a Moon Base and develops an enduring human presence there. Postflight crew health, performance data In the hours, days, and weeks after landing, the Artemis II crew members, NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, contributed critical data to help the agency understand how the human body reacts to spaceflight. Collecting this data as soon as possible after landing was important to understand how the body adapts from microgravity to Earth’s gravity. The data will inform NASA’s understanding of how quickly crews can complete mission-critical tasks after landing on a planetary surface like the Moon or Mars, where there won’t be landing support personnel to assist. Within a day of splashdown, researchers collected a suite of data for the Artemis II Spaceflight Standard Measures study, which is part of a larger effort across the astronaut corps to gather a baseline set of health measurements on blood pressure, heart rate, eye health, and motor control. Crew members also completed a mini obstacle course, which included lying down, standing up, unfurling a rope ladder, ladder climbing, and more, to assess how their bodies were adapting to Earth’s gravity. Once the crew returned to NASA’s Johnson Space Center in Houston, researchers guided them through further medical check-ups and tests of motor control . Over the next several days, the crew completed obstacle courses wearing spacesuits offloaded to lunar gravity, which is roughly one-sixth the force of Earth’s gravity. Researchers are now analyzing this data to gain insight into how crews may perform as they adapt to the gravity of a planetary surface. As part of the Immune Biomarkers study, researchers are comparing blood and saliva samples collected after the Artemis II splashdown with samples collected preflight and during the mission. Among other topics, the study investigates whether and how dormant viruses reawaken in astronauts’ bodies while in space. Some crew members completed postflight cognition tests and a simulated manual spacecraft docking task to assess motor control for the ARCHeR ( Artemis Research for Crew Health & Readiness ) study. This, combined with data collected through a wrist-worn device while crew members were in space, is used to understand the effect of space hazards on well-being and performance. Initial data collections for Artemis II health studies concluded 45 days after splashdown. However, medical teams will continually monitor astronaut health throughout the Artemis II crew members’ lifetimes. Once this data is processed and anonymized, information will be available for scientists to study the effects of spaceflight via a request to NASA’s Life Sciences Data Archive . The results from this work could lead to new technologies and studies that help predict the adaptability of crews on future missions to the Moon and Mars. Analyzing astronaut-derived organ chips flown around Moon A scientist handles AVATAR organ chips following their journey around the Moon aboard Orion. The chips contain cells from each astronaut and are being prepared for detailed analysis. NASA Organ chips from NASA’s AVATAR ( A Virtual Astronaut Tissue Analog Response ) investigation are being analyzed at chip developer Emulate’s laboratory in Boston. The organ chips included bone marrow cells from each Artemis II astronaut. They flew around the Moon with the astronauts, and now researchers are studying these organ chips to determine how deep space radiation and microgravity affect human health at the molecular level. Scientists are comparing the chips flown aboard the spacecraft to ground controls and crew blood samples using advanced techniques, including single-cell RNA sequencing. The analysis will characterize how organ chips model individual responses to spaceflight, which is data that could allow NASA to send future astronauts’ AVATAR chips ahead on missions to develop personalized medical kits. The researchers plan to share early findings at scientific conferences while full analysis continues. Lunar imagery, audio for data release In this April 3, 2026, image, the Artemis II lunar science team is shown working in the Science Evaluation Room in the Mission Control Center at NASA’s Johnson Space Center in Houston. The team is putting together a plan of science observations for the Artemis II crew, which was headed toward the Moon aboard Orion. As they passed the Moon at closest approach on April 6, the crew applied the geology skills they learned in the classroom and in Moon-like environments on Earth as they photographed and described nuances of geologic features such as impact craters, ancient lava flows, and surface cracks and ridges. The crew noted differences in color, brightness, and texture — details that provide clues to surface composition and history. NASA/Bill Stafford On April 6, the Artemis II crew members studied features on and around the Moon for nearly seven hours during Orion’s closest approach to the lunar surface. Their work was guided by a minute-by-minute observation plan developed by the Artemis II lunar science team. Scientists are reviewing the data collected from the mission, which includes images, video, and audio files, to release a report of their initial data interpretations later this year. The report will cover observations of impact flashes, variations in color on the lunar surface, and the shape and texture of faults and ridges. The team also will publish a report on how Artemis II lunar science observations were planned, organized, and executed for the benefit of future Artemis missions. NASA will publish more than 100 science-related audio recordings with transcripts, as well as approximately 11,500 Earth and Moon image and video files from the mission science campaign, with accompanying data. While many of these images already are public, these records will be available through NASA’s Planetary Data System , a public archive of data from all of NASA’s planetary missions. To get the data ready, the team is converting files into standard formats that anyone can easily open and add information to make the data searchable in NASA’s archive for generations to come.

NASA Concludes Antenna Mishap Investigation, Releases Report

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This sunset photo shows Deep Space Station 14, the 230-foot-wide (70-meter) antenna at the Goldstone Deep Space Communications Complex near Barstow, California, part of NASA’s Deep Space Network. NASA/JPL NASA has completed the investigation into the damage sustained last year at its 70-meter radio-frequency antenna, known as the Deep Space Station 14 (DSS-14), at the Goldstone Deep Space Communications Complex near Barstow, California. The agency has classified the event as a Type A mishap based on the total cost of damages. The antenna will remain offline to complete repairs and previously scheduled upgrades. “NASA takes safety and any departure from established procedures seriously, and the investigation at Goldstone made clear that we must strengthen our processes. We are acting on the investigation’s findings,” said Joel Montalbano, acting associate administrator for NASA’s Space Operations Mission Directorate at the agency’s headquarters in Washington. “We will update and improve procedures, rebuild core in-house capabilities, and reinforce operational discipline across the Deep Space Network. NASA remains focused on learning from this and modernizing systems, so DSS-14 and the broader network are ready to support our ambitious future missions.” On Sept. 16, 2025, the DSS‑14 antenna over‑rotated while actively tracking the Juno mission, placing excessive stress on cabling and associated structural supports. Water lines tied to the antenna’s fire‑suppression system also were damaged, causing significant flooding in the facility. There were no injuries. NASA convened a Mishap Investigation Board, bringing together experts from across the agency to examine the technical, organizational, and cultural factors behind the incident. The board conducted on‑site inspections, interviews, and detailed reviews of technical documentation and operational logs from all three Deep Space Network sites. The board completed its final report in April and submitted it for agency concurrence. The investigation issued findings and recommendations that emphasize training, technical rigor, operational procedures, system design, clear roles and responsibilities, and safety assurance. At the same time, teams already are applying lessons learned across all network sites to improve operational consistency. These steps will help bolster the network and reduce the risk of future mishaps. In its final report, the board found the mishap primarily stemmed from software weaknesses, human error, and an undetected failure in the antenna’s hydraulic limit system. Investigators determined an electrical issue at the antenna the previous day caused the control system to misreport the antenna’s rotation state, an issue that went unnoticed and triggered multiple limit-stops during the Juno track on Sept. 16. While working to identify the limit-stop problem, operators performed several troubleshooting steps that inadvertently bypassed software and hardware safeguards, which ultimately led to the over-rotation incident. After flooding in the antenna base was observed, operators attempted to stow the antenna as a safety precaution, however, because the system had already passed the rotation limits, this action drove the antenna further into over‑rotation, causing additional damage. Additionally, the investigation found the antenna’s hydraulic limit system, its final mechanical safeguard, was inoperable on Sept. 16 after being damaged in an undocumented prior incident. The system also had not been adequately tested for an undetermined period of time. Investigators also concluded workplace culture pressured operators to work as expeditiously as possible, often stretching beyond their usual roles, expertise, and training, to keep the antenna operating. The board states the cultural conditions observed at Goldstone were not present at the network’s other sites, where roles and responsibilities are followed more consistently. Other contributing factors outlined in the report include inadequate procedures, reliance on undocumented practices and tacit knowledge, and gaps in the antenna’s control logic. NASA will accept this as the final report. The agency estimates repairs will cost between $4.1 and $4.6 million, with a final figure to be determined after the antenna’s systems are fully assessed. The antenna will remain offline as it enters its previously scheduled extended maintenance and upgrade period, originally set to begin in August and expected to be completed by October 2028. These upgrades are part of broader network improvements essential to supporting future exploration and science missions, as well as enhancing the nation’s planetary defense capabilities. “We are committed to learning everything we can from this incident, and we’ve already begun putting those lessons into practice,” said Kevin Coggins, deputy associate administrator for NASA’s SCaN (Space Communications and Navigation) Program at the agency’s headquarters. “Our teams are working to strengthen and standardize processes and training across all three network sites to ensure it remains resilient, consistent, and ready to support the next generation of missions. Every challenge is an opportunity to improve, and this is no exception.” The Deep Space Network continues to provide full coverage for more than 40 missions despite the DSS‑14 incident. The network’s 13 other antennas, located at complexes in California, Australia, and Spain, are supporting all tracking needs without interruption. A dedicated scheduling team allocates antenna time across the network to meet each mission’s science and data‑return objectives. The team also maintains continuous coverage when an antenna goes offline for maintenance or an unexpected outage.

NASA Satellites Help Map Ocean Nutrient Stress

Warming waters decrease upwelling and lead to stress on marine microorganisms due to limited availability of vital nutrients. Red indicates the regions of highest nutrient-related stress. Kel Elkins/NASA’s Scientific Visualization Studio Editor’s note: This article was updated on June 5. A new study combining NASA satellite observations, ocean surveys, and genetic testing on marine microorganisms found evidence that warming ocean waters may be limiting nutrient availability across much of the global ocean. The researchers report that this nutrient stress affects microscopic marine organisms and could influence marine ecosystems over time. The research, published June 5 in Science Advances, tracked the condition of phytoplankton , which form the base of ocean food webs. Rather than measuring nutrients like nitrogen, iron, and phosphorus directly, the researchers inferred stress by tracking subtle shifts in the ratio of carbon to chlorophyll in phytoplankton observed from space. When the amount of chlorophyll decreases relative to carbon as seen in satellite data, it’s an indication that the plankton are stressed. “As our ocean continues to change, the ability to observe and track ocean conditions through sustained, high quality remote sensing observations has never been more important,” said Laura Lorenzoni, Program Scientist for NASA’s Ocean Biology and Biogeochemistry Program at NASA Headquarters in Washington. “This is fundamental, as plankton communities are the base of the marine food web on which important economic activities rely.” The research team combined two decades of data from NASA’s Aqua satellite’s Moderate Resolution Imaging Spectroradiometer (MODIS) sensor with plankton samples collected on research cruises around the world. The approach linked large-scale satellite observations with genetic markers in Prochlorococcus, a tiny but abundant marine microbe that shows signs of nutrient stress in its DNA. The result is a global map revealing where phytoplankton are thriving and where they’re struggling.

Marit Jentoft-Nilsen/NASA’s Goddard Space Flight Center The strongest indications of nutrient stress on plankton appeared in the subtropical gyres, which are vast, relatively calm regions of the Atlantic, Pacific, and Indian oceans. In these areas, a layer of warm surface water stifles the flow of colder water from deeper in the ocean. “When the surface of the ocean warms, it generates this very stable situation where a layer of low-density water sits on top of higher-density cold water,” said study coauthor Adam Martiny, an oceanographer at the University of California, Irvine. “You’ve probably experienced that if you’ve ever been to a lake in the summertime—it’s super warm right on the surface, and very cold deeper down when you stick your legs in.” This layering blocks the upward flow of nutrient-rich water, limiting the availability of ocean surface nutrients that are crucial for plankton. In the South Pacific, one of the most nutrient-poor regions, a layer of warm surface water contributed to nitrogen and iron shortages, producing the most severe nutrient-related stress that the team discovered. But the researchers were surprised to find that parts of the North Atlantic experience less nutrient stress than expected. Although there was evidence of a lack of phosphorus, the impact on microorganisms was comparatively mild. That difference may reflect the biology of the organisms themselves. Phytoplankton can partially compensate for phosphorus shortages by recycling phosphorus more efficiently or replacing phosphorus-rich molecules inside their cells. Nitrogen shortages are harder to overcome because nitrogen is crucial for the proteins and cellular machinery required for photosynthesis and nutrient uptake. The study revealed that nutrient stress is strongly correlated with seasons and major weather cycles such as El Niño and the Pacific Decadal Oscillation, which lead to warming waters in the Pacific Ocean. During La Niña events, which cool water over a large part of the Pacific, stronger upwelling brought more nutrients to surface waters and reduced stress in some regions. Superimposed on those multi-year cycles, however, was a longer-term trend. From 2002 through 2021, average sea-surface temperatures increased across nearly 90% of the ocean area examined in the study. Over the same period, nutrient stress generally intensified, consistent with previous hypothesis that warming oceans may become increasingly stratified and less able to replenish surface nutrients. In many nutrient-poor regions of the Southern Hemisphere, however, the researchers found evidence that nutrient stress had not increased as much as expected despite significant warming. They suspect that microbes capable of capturing nitrogen from the air may partially offset the effects of reduced nutrient mixing. That finding hints that marine ecosystems may possess more resilience to warming climates than some models predict. It also underscores the complexity of forecasting how ocean biology will respond to continued warming. “We have two really powerful tools,” said study coauthor Michael Behrenfeld, a biochemist with Oregon State University in Corvallis, Oregon. The tools include satellite observations and cellular studies. “Both produce big data sets, but they are kind of opposites. We have very detailed data about microscopic phytoplankton … and then we have global coverage with satellites.” By combining satellites that monitor the entire ocean with genetic clues carried inside microscopic plankton, the researchers say they are gaining a new way to track biological responses to changing environmental conditions near real time.

First Steps: America’s Grueling Second Spacewalk

A year after America’s first spacewalk, Gemini IX-A Eugene Cernan stepped outside his spacecraft for an ambitious extravehicular activity scheduled for 167 minutes. The challenges he faced led NASA to reevaluate plans, equipment, and training for future spacewalks. NASA One year after Gemini IV astronaut Edward H. White completed NASA’s first spacewalk the agency prepared for a demanding second excursion. Originally scheduled for Gemini VIII, the extravehicular activity (EVA) was reassigned to Gemini IX-A after that mission ended early, with Gene Cernan taking on the task. On June 5, 1966—the mission’s third day—Cernan exited the spacecraft and quickly found himself fighting his own equipment. His spacesuit was so rigid that even simple movements required intense effort. He struggled to complete the simplest maneuvers. Within minutes, Cernan was exhausted and sweating profusely. His spacesuit was cooled only through the circulation of oxygen and as he worked to complete the goals of the EVA, his helmet fogged over completely, obstructing his view and his heart rate rose to about 180 beats per minute. As concerns grew that he might lose consciousness, the EVA was called off and Cernan’s spacewalk ended after two hours and eight minutes. When Gemini IX-A returned to Earth, doctors found that Cernan had lost 13 pounds during the three-day mission, most of it water lost during his EVA. The challenges Cernan faced that day reshaped NASA’s approach to spacewalking. His experience directly influenced improved training methods, refined EVA procedures, and precipitated advances in spacesuit design—key steps in preparing astronauts for lunar surface missions just a few years later.

NASA Earth Observatory/Michala Garrison In May and June of most years, NASA satellites typically begin to detect large numbers of wildland fires throughout the Top End and Arnhem Land regions of Australia’s Northern Territory. On some days, especially in the afternoon, the blazes can resemble sizable wildfires in satellite imagery, spreading widely and producing expansive smoke plumes. That was the case when NASA’s Aqua satellite acquired this image of smoke and fires on the afternoon of May 28, 2026 . Often, however, fires burning in this area look smaller and less imposing. In the mornings just a few days earlier and later , for instance, NASA satellites detected little smoke despite observing many thermal anomalies , or hotspots, that indicated fire activity. The pattern of burning, location, and timing are consistent with prescribed fires lit intentionally to manage the landscape. Land managers tend to light fires in the morning, and smoke builds over the course of the day. The process sometimes creates sizable plumes when there are updrafts and winds of moderate strength that carry smoke away from the fires, as happened on May 28 and again on June 2 . The fires typically burn through the fire-adapted grasses, underbrush, and scattered trees in the region’s tropical savanna ecosystems . Over the past few decades, the region’s land managers have combined deep-rooted Indigenous land management practices and modern technologies to establish large-scale landscape management programs such as the West Arnhem Land Fire Abatement project and Arnhem Land Fire Abatement . The goal of such efforts is to intentionally burn some of the savanna underbrush to create firebreaks and reduce fuel loads early in the dry season, reducing more destructive and emissions-intensive fires later in the season. The dry season generally begins in May and extends through September, according to Australia’s Bureau of Meteorology . While research is ongoing, there are signs that the prescribed burning efforts are having the intended effect. Analysis of satellite observations of the fires suggests that prescribed burning efforts have shifted fire activity from late to early in the dry season, leading to a reduction in high-intensity fires and emissions.

NASA Hosts 2026 Review on Advanced Composite Manufacturing

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Boeing assembles a composite aircraft fuselage section in one of its production facilities. Composite materials are used in major portions of modern aircraft, including sections of the fuselage and wings on aircraft such as the Boeing 787. NASA’s HiCAM project aims to help accelerate manufacturing processes for future composite aircraft. Boeing NASA’s Hi-Rate Composite Aircraft Manufacturing (HiCAM) project brought together its full team of Advanced Composites Consortium partners for a 2026 spring review at NASA’s Langley Research Center in Hampton, Virginia.   The meeting took place May 5-7, bringing together about 150 people from the consortium, a 22-member public-private partnership.   The review gave NASA and industry partners a chance to look at recent progress and plan for the work ahead. NASA announced recent portfolio decisions, selecting technologies that can have the greatest impact on manufacturing rate for the next airplane program.    During the meeting, teams reviewed the latest results from the project’s Development Phase and discussed early progress under Phase 2, known as the Demonstration Phase. This phase will scale up key manufacturing technologies in the coming years.   A major part of the event included full-day workshops focused on assembly demonstrations of two large aircraft structures: the wing and fuselage. These sessions brought together NASA researchers, industry engineers, and partners to share updates, exchange ideas, and discuss long-term plans. Many teams said they noticed stronger collaboration and coordination across the group this year.   That collaboration supports HiCAM’s goal of large-scale manufacturing demonstrations of a composite fuselage barrel and wing box in 2028 and 2029. These demonstrations represent major project milestones and will help show how advanced composite materials and processes could support faster, lower cost aircraft production.   NASA and its partners continue to make steady progress toward the project’s goals. The project’s work could help pave the way for new manufacturing methods for lightweight composite structures that make future aircraft easier to build and more efficient to operate.

NASA-Funded Study Shows Wildfire Smoke’s Hidden Ozone Toll

Earth (ESD) Earth Explore Explore Earth Science Agriculture Air Quality Climate Change Freshwater Life on Earth Severe Storms Snow and Ice The Global Ocean Science at Work Earth Science at Work Technology and Innovation Powering Business Multimedia Image Collections Videos Data For Researchers About Us 5 Min Read NASA-Funded Study Shows Wildfire Smoke’s Hidden Ozone Toll Canadian wildfire smoke carried carbon monoxide — a building block of ground-level ozone — thousands of miles downwind in June 2023. Credits: NASA’s Goddard Space Flight Center Wildfire smoke is stoking a new challenge for cleaner air. A NASA-supported study published Thursday found that, over the last decade, wildfires have worsened ground-level ozone pollution across much of the contiguous United States, creating unhealthy air far from active flames. Wildfires have become an increasingly important contributor to ground-level ozone, or smog, across much of the United States, researchers report June 4 in the journal Science . Nationally, fires offset nearly four years’ worth of ozone-control gains, with larger setbacks in the West and Midwest. Smoke often is associated with the soot, ash, and other fine particles that make the air look hazy. But wildfires also emit gases such as carbon monoxide, which can help form surface ozone in sunlight when other pollutants are present. Surface ozone is an invisible pollutant harmful to human health, plants, and crops. As smoke plumes travel and mix with other pollution, those reactions can drive ozone increases hundreds or even thousands of miles from active fires. “NASA Earth observations, along with ground monitoring networks, help reveal air quality risks from wildfires that can cross state lines, giving air quality managers better decision-making information as wildfire smoke affects more communities,” said John Haynes, manager of NASA Earth Action’s Health and Air Quality program at the agency’s Headquarters in Washington. “This is a strong example of NASA science serving communities here in the U.S.” Building a clearer ozone picture High in the atmosphere, ozone shields Earth from harmful ultraviolet radiation . Near the ground, however, ozone can irritate lungs, worsen asthma and other respiratory diseases, and increase health risks for children, older adults, outdoor workers, and people with existing health conditions. To track surface ozone changes, researchers turned to deep learning, a form of artificial intelligence that finds patterns across large datasets. They used it to build a first-of-its-kind dataset estimating daily surface ozone from 2003 to 2024 on a kilometer-by-kilometer grid — about 0.6 miles on each side — across the contiguous U.S. The work received support from NASA’s Health and Air Quality program and other NASA grants. The scientists combined data from about 1,000 ground-based air quality stations with atmospheric model data, weather information, wildfire pollution data, and satellite-derived information, including products from the Visible Infrared Imaging Radiometer Suite ( VIIRS ) and the Moderate Resolution Imaging Spectroradiometer ( MODIS ) instruments. Smoke from Canada’s 2023 wildfires spread across North America. Tan to deep red colors show smoke intensity, estimated from black carbon in NASA’s GEOS-FP model. NASA’s Scientific Visualization Studio (SVS) and NASA’s Global Modeling Assimilation Office (GMAO) Their analysis revealed two distinct periods. From 2003 to 2015, U.S. ground-level ozone generally declined as emissions of ozone-forming pollutants decreased. After 2015, however, those gains slowed or reversed in many places. By comparing estimated ozone levels with scenarios that removed wildfire influence, the researchers found that pollution from wildfires was a main factor in that shift. Without the wildfire contribution, ground-level ozone in the Midwest, for example, would likely have continued to decline. Instead, wildfires erased about 5.3 years’ worth of ozone-control progress since 2015. “People in the Midwest may think fires burning far away will not affect them,” said the study’s corresponding author Jun Wang, an atmospheric scientist at the University of Iowa in Iowa City. “But once wildfire pollution is in the air, it can move across regions. Pollution from one place can affect air quality in another.” Measuring the health toll The study also found that wildfire-driven ozone increased exposure to unhealthy air and likely contributed to premature deaths. Premature deaths associated with long-term wildfire-related ozone exposure in the U.S. increased by an estimated 318 deaths per year after 2013, with the post-2013 average 46% higher than in the previous decade. The researchers calculated premature deaths using average lifespan, ozone exposure estimates, and population density. The 2023 Canadian wildfires showed how widely those risks can spread, with smoke-driven ozone increases stretching across the Midwest and into parts of the Northeast and South. Overall, from 2022 to 2024, wildfires exposed an additional 43 million people in the U.S. to conditions that did not meet current federal air quality standards for ozone, the researchers estimated. Capturing that national picture is difficult from ground monitors alone. Ground monitors remain the backbone of U.S. air quality tracking, but they do not cover every community. NASA’s scientifically validated satellite observations and models help researchers and agencies see air quality patterns across states, regions, and fire seasons. That broader air quality work includes newer missions such as TEMPO (Tropospheric Emissions: Monitoring of Pollution). Launched in 2023, TEMPO is NASA’s first mission to use a space-based spectrometer to provide hourly daytime measurements of air quality over North America. Its view is sharp enough to distinguish pollution patterns, including surface ozone, across areas only a few square miles wide, a major improvement over earlier satellites. Together, these capabilities help researchers and agencies see smoke-related ozone patterns that might otherwise be harder to detect, especially in rural and remote areas. The work also points toward a practical use of NASA science during fire season.

Colorful, Chaotic Jupiter

NASA/JPL-Caltech/SwRI/MSSS; Image processing by Gary Eason © CC BY NASA’s Juno spacecraft captured this color-enhanced view of Jupiter’s northern hemisphere during its 61st close flyby of the giant planet on May 12, 2024. Citizen scientist Gary Eason made this image using raw data from the JunoCam instrument, applying digital processing techniques to enhance color and clarity. It provides a detailed view of chaotic clouds and cyclonic storms in an area known to scientists as a folded filamentary region. In these regions, the zonal jets that create the familiar banded patterns in Jupiter’s clouds break down, leading to turbulent patterns and cloud structures that rapidly evolve over the course of only a few days.

A Moonlit Earth as Seen From Artemis II

In a single image, Earth’s full disk appears amid celestial phenomena that illustrate its place in the solar system. And although the visible hemisphere appears to be awash in sunlight, it is actually lit by moonlight. The astronauts’ vantage point provided a rare opportunity to capture nighttime features—most notably lights from human habitation—from a new perspective. An Artemis crew member captured the photo from the Orion spacecraft after it completed the translunar injection burn , which sent the spacecraft out of Earth orbit and on a trajectory toward the Moon. In the photo, Earth eclipses the Sun from Orion’s perspective, leaving only a small sliver of its bright light visible around the bottom right edge. Green auroras, caused by charged particles from the Sun interacting with Earth’s upper atmosphere, glow around the north and south poles (lower left and upper right, respectively). The Sun’s light also produces the fuzzy glow, known as zodiacal light , that appears to the lower right of Earth. This phenomenon comes from sunlight reflecting off interplanetary dust. Skywatchers on Earth may see it at certain times of year around dawn or dusk as a faint column of light extending up from the horizon. Data collected by NASA’s Juno spacecraft on its journey to Jupiter suggest that Mars may be a significant source of the dust particles that produce zodiacal light. Earth’s other planetary neighbor, Venus, appears as the bright object in the bottom right of the image. April 2, 2026 On Earth itself, city lights are evidence of human activity. Bright areas appear in Spain, Portugal, and northern Africa (lower left), sub-Saharan Africa (center left), and Brazil (center right). Digital camera technology—with help from the illumination of a full Moon—made it possible to see these and other details of Earth’s surface and atmosphere in low light. The crew set the camera’s ISO to 51,200 to make it highly sensitive to light. For comparison, an ISO setting of 100 or 200 is common for daytime photography. Previous nighttime views of Earth taken from spacecraft may look very different from this photo but have also inspired and enlightened. For instance, the Apollo 12 crew photographed Earth eclipsing the Sun in 1969; astronaut Alan Bean would go on to depict his impressions of the event in paintings . More recently, astronauts aboard the International Space Station have photographed the planet at night from low Earth orbit, while NASA’s Black Marble nighttime lights product suite uses satellite observations to produce science-quality records of nighttime lights at daily, monthly, and yearly time scales. Those programs provide sustained data records, while the Artemis II photo is distinctive as a single human-captured full-disk view showing many low-light features at once. Cindy Evans , senior exploration scientist in the Astromaterials Research and Exploration Science Division at NASA’s Johnson Space Center, was working in the Science Evaluation Room during the Artemis II mission and was one of the first people on Earth to see the image. Evans was struck both by its beauty and the perspective revealed by all the visible solar system features. “I love the image so much because it was taken with Earth in moonshine, and shows Earth as a solar system body, a dynamic planet interacting with the solar wind, and a place harboring life,” she said. The image is scientifically valuable, as well, said Miguel Román , Deputy Director for Atmospheres and Data Systems at NASA’s Goddard Space Flight Center. “It speaks powerfully to the breadth of what NASA does across science and human exploration,” he said. Román studies artificial light at night, as viewed from space, as a measurable signal of human activity. “[This photo] reminds us that Earth at night is visually compelling, physically complex, and scientifically underexplored,” Román said. “I see this image as a glimpse of what Earth science can become in the future.” NASA images prepared for Earth Observatory by Lauren Dauphin.

NASA’s Mars rover Curiosity acquired this image of the inlet on its Chemistry & Mineralogy X-Ray Diffraction instrument (CheMin), which is about the size of a laptop computer and sits inside rover’s body, where it analyzes the chemical composition of rocks and soil. Curiosity captured the image using its Mars Hand Lens Imager (MAHLI), a close-up camera located on the turret at the end of the rover’s robotic arm, on May 28, 2026 — Sol 4908, or Martian day 4,908 of the Mars Science Laboratory Mission — at 11:14:14 UTC. NASA/JPL-Caltech/MSSS By Susanne P. Schwenzer, Professor of Planetary Mineralogy at The Open University, UK Earth planning date: Friday, May 29, 2026 Drilling always keeps the rover in place for a little while, and our 47th successful drill, “Campo Marte,” was no exception. The team used the time wisely and on top of the drilling, we also have many observations. Thinking for a long time about a workspace always gets me attached to the area — some more than others; at the shorter stops, especially — when I am on shift several times during this time. I was Science Operations Working Group chair three times while we were here, so it’s a real “Goodbye” for me today as we are driving onward to reach the next area up the hill on Mount Sharp. The Campo Marte drill was successful, as my colleague Abigail Fraeman reported last week . This week was spent investigating the aftermath of the drilling, which means running the CheMin instrument to get mineralogical data and the SAM instrument to inspect the volatile releases. ChemCam, APXS, MAHLI and Mastcam were also busy documenting the drill hole and the drill fines, as well as how much sample there was available overall. Of course, Curiosity also had a very good look at the other interesting targets in the area! Besides all the work on the drill hole, ChemCam carried out an expert’s targeting exercise by setting two targets up to aim at two different layers on adjacent spots on the finely laminated sediments. That involves aiming at millimeter-sized targets, named “Corcovado” and “Junakas,” respectively, about 3 meters away (about 10 feet)! We are curious if the layers are chemically different, which would tell us about different formation conditions, or if they are similar and the conditions when those layers formed were more similar. ChemCam is also looking at the target “Palcaya” to get more data on the chemistry of the layered bedrock, and will investigate the target “Alcamachi,” which is a float rock that looks intriguingly dark. Maybe that tells us it’s got a different chemistry? We will find out when we get the data! In addition to the chemistry measurements, ChemCam will also carry out a spectral investigation on the target “Magallanas,” which was a little too far away to also point the laser at it, but is intriguingly dark. This last week, ChemCam also planned three long-distance RMIs to document the sedimentary structures — younger and older ones — in the surrounding area. One of them drew the suspicion that it might break a record: it might be the longest strip of RMI images we have taken in one mosaic! The jury is out, it’s 24 frames and this way links up with an earlier, shorter set of images. The reason the mosaic is so long is because it images a small ridge with sedimentary textures that could tell us about the depositional conditions when the rock layers formed. But how cool is that — at 13+ years to still break our own records? Since our arrival, Mastcam has been very busy getting the entire region around us imaged. In addition, some higher-resolution mosaics have been taken, most notably one of the locations where the remaining sample was dropped, and then of the workspace to see again how much sample might — or might not — have been left in the drill stem and fallen out when Curiosity did the motions that are designed to shake any remaining sample out of the drill, to leave it prepared for the next time. Another imaging task, but for MAHLI, is to always image the sample inlets, also, to see if they are clean and prepared for the next sample. I included the MAHLI image of the CheMin inlet — don’t worry about the little rock, it’s with us for a while, and the CheMin team now calls it “our pet rock.” APXS joined the drill-hole investigations and has been focused on it even more than usual. The team decided that this is a very good opportunity to increase counting statistics beyond the usual and well-tested levels by significantly increasing the measurement time. To achieve that, it measured the Campo Marte drill fines in all plans of this week. And on the last night of that, MAHLI gets out its LED lights to finish the experiment with a sparkling nighttime MAHLI experiment to document it all. Our environmental team has kept the rover busy by looking at atmospheric opacity, dust activity, dust-devil activity and, of course, also monitoring the environment in general. With all this finished, the rover will continue its way up the hill to the next interesting area. I heard something like “cross-bedding” during the discussions, but as a mineralogist, I just note that that decision was taken by people who know more about sediments than I do, while I am itching to see the CheMin mineralogy results!

NASA Finds New Way Earth May Have Received Elements Needed for Life

4 Min Read NASA Finds New Way Earth May Have Received Elements Needed for Life This is an artist’s impression of a young star surrounded by a protoplanetary disk. Darker rings in the disk are where objects like planetesimals are forming, clearing a path through the debris. Credits: Illustration: ESO NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable. They also suggest a new role for Jupiter in the distribution of these elements throughout the young solar system. The study, published today in Science Advances , examines this history by looking at the ratio of phosphorus to nitrogen in iron meteorites and in younger objects known as chondrites. The study suggests that Earth acquired its inventory of the life-essential elements phosphorous and nitrogen primarily from the inner solar system, without requiring a significant contribution from outer solar system chondrites Debjeet Pathak Rice University Planetary system formation Our solar system formed from gas and dust that swirled around the proto-Sun more than 4.5 billion years ago. This gas contained the raw materials needed to form planets, moons, and ultimately life as we know it. Two elements of particular importance for life are nitrogen and phosphorus. All life on Earth needs the same elements: carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur (CHNOPS). These elements came from space, born inside stars and spread in clouds of gas and dust. Gravity then caused this material to gather together, forming new stars and smaller objects like planets. NASA In the earliest stages of the solar system, gas and dust coalesced into bodies known as planetesimals. As these objects orbited the young Sun in this chaotic environment, planetesimals collided, leaving shattered remnants throughout the system. Eventually, many of these pieces were incorporated into planets and moons. Other pieces survive today as asteroids, still orbiting the Sun, and – if they have impacted the Earth and been recovered – as meteorites. These meteorites provide a window into the early solar system at a time before the Earth existed. Chondrites and iron meteorites are two different classes of these meteorites. As their name suggests, iron meteorites are dense, metallic objects and are primarily made of iron-nickel alloy. Chondrites, on the other hand, are stony objects and they are responsible for most of the meteorites that have been found on Earth. Each type of meteorite originates from planetesimals that formed at different times in our system. The oldest generation of planetesimals are the source of iron meteorites. Chondrites came from a second generation of planetesimals that formed 2-3 million years later. Habitable planet building Understanding how the Earth was made and the timing of its formation is important for astrobiologists who study how and when our planet became habitable for life as we know it. The young Earth needed to have a supply of life’s ingredients, including nitrogen and phosphorus, for the first living cells to form. There is debate between scientists over where Earth’s stock of life-essential elements came from. Some evidence points to chondrites in the outer solar system traveling inward to arrive at Earth late in our planet’s formation process. However, the new study tells a different story. Using laboratory experiments and geochemical models, the team reconstructed a map of phosphorus-nitrogen (P/N) ratios across the early solar system and found differences between the first (iron meteorites) and second (chondrites) generations of planetesimals. An illustration of our solar system. The asteroid belt is located between Mars and Jupiter, separating our system into what we refer to as the inner and outer regions. NASA/JPL-Caltech The experiments and subsequent geochemical modeling showed that the first generation had a higher ratio of P/N in the outer solar system, with that ratio decreasing toward the inner solar system. This trend was reversed in the second generation of planetesimals, with higher P/N ratios in the inner solar system. The thought is that during the formation of the first generation of planetesimals, there was an outward flow of material that raised the P/N ratio in the outer solar system. Then came Jupiter. For our own solar system, Jupiter’s presence and growth history, indeed, seem to have played a critical role in determining the distribution of the basic chemical ingredients necessary for habitable worlds. Rajdeep Dasgupta Rice University As Jupiter formed and grew to a tremendous size (and gravitational influence), the planet restricted the movement of phosphorus and nitrogen from the inner to outer solar system. This meant that when the second generation of planetesimals appeared, those in the inner solar system were left with a higher P/N ratio than their cousins further out. “For our own solar system, Jupiter’s presence and growth history, indeed, seem to have played a critical role in determining the distribution of the basic chemical ingredients necessary for habitable worlds,” said Rajdeep Dasgupta of Rice University in Houston and senior author on the study. “It remains an open question whether a life-essential element budget similar to Earth’s can be established without a Jupiter-like planet in the population.” Geochemical accretion modeling further shows that Earth’s present-day P/N signature is best reproduced by the inner solar system planetesimals, either those related to iron meteorites or those related to chondrites. “The study suggests that Earth acquired its inventory of the life-essential elements phosphorous and nitrogen primarily from the inner solar system, without requiring a significant contribution from outer solar system chondrites,” said study lead author Debjeet Pathak, graduate student at Rice University.
