Four Private Astronauts are About to Make a Polar Orbit for the First Time
It’s getting a little harder to be the first humans to achieve something but, if all goes to plan, a team of four private astronauts are expected to head off into a polar orbit around Earth aboard the SpaceX Dragon capsule today (31 March) at 9:46pm ET and take the crew over the North and South Poles of Earth. Financed by Chun Wang, a Malta-based investor, they are planning a series of experiments, including attempting to grow oyster mushrooms in microgravity, which could eventually become a source of food for space missions.

How Can We Find Cryovolcanoes on Europa?
Astronomers suspect that Europa has cryovolcanoes, regions where briny water could erupt through Europa's ice shell, throwing water—and hopefully organic molecules—into space. NASA's Europa Clipper and ESA's JUICE mission are on their way and will be able to scan the surface of the icy moon for signs of cryovolcanism. What should they be looking for? Pockets of brine just below the surface could be active for 60,000 years and should be warmer than their surroundings.

Preparations for NASA’s next Artemis flight recently took to the seas as a joint NASA and Department of Defense team, led by NASA’s Exploration Ground Systems Program, spent a week aboard the USS Somerset off the coast of California practicing procedures for recovering the Artemis II spacecraft and crew.
Following successful completion of Underway Recovery Test-12 (URT-12) on Monday, NASA’s Landing and Recovery team and their Defense Department counterparts are certified to recover the Orion spacecraft as part of the upcoming Artemis II test flight that will send NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, as well as CSA (Canadian Space Agency) astronaut Jeremy Hansen, on a 10-day journey around the Moon.
“This will be NASA’s first crewed mission to the Moon under the Artemis program,” said Lili Villarreal, the landing and recovery director for Artemis II. “A lot of practice led up to this week’s event, and seeing everything come together at sea gives me great confidence that the air, water, ground, and medical support teams are ready to safely recover the spacecraft and the crew for this historic mission.”

Once Orion reenters Earth’s atmosphere, the capsule will keep the crew safe as it slows from nearly 25,000 mph to about 325 mph. Then its system of 11 parachutes will deploy in a precise sequence to slow the capsule and crew to a relatively gentle 20 mph for splashdown off the coast of California. From the time it enters Earth’s atmosphere, the Artemis II spacecraft will fly 1,775 nautical miles to its landing spot in the Pacific Ocean. This direct approach allows NASA to control the amount of time the spacecraft will spend in extremely high temperature ranges.
The Artemis II astronauts trained during URT-11 in February 2024, when they donned Orion Crew Survival System suits and practiced a range of recovery operations at sea using the Crew Module Test Article, a stand -in for their spacecraft.
For the 12th training exercise, NASA astronauts Deniz Burnham and Andre Douglas, along with ESA (European Space Agency) astronaut Luca Parmitano, did the same, moving from the simulated crew module to USS Somerset, with helicopters, a team of Navy divers in small boats, NASA’s open water lead – a technical expert and lead design engineer for all open water operations – as well as Navy and NASA medical teams rehearsing different recovery scenarios.

“Allowing astronauts to participate when they are not directly involved in a mission gives them valuable experience by exposing them to a lot of different scenarios,” said Glover, who will pilot Artemis II. “Learning about different systems and working with ground control teams also broadens their skillsets and prepares them for future roles. It also allows astronauts like me who are assigned to the mission to experience other roles – in this case, I am serving in the role of Joe Acaba, Chief of the Astronaut Office.”

As the astronauts arrive safely at the ship for medical checkouts, recovery teams focus on returning the spacecraft and its auxiliary ground support hardware to the amphibious transport dock.
Navy divers attach a connection collar to the spacecraft and an additional line to a pneumatic winch inside the USS Somerset’s well deck, allowing joint NASA and Navy teams to tow Orion toward the ship. A team of sailors and NASA recovery personnel inside the ship manually pull some of the lines to help align Orion with its stand, which will secure the spacecraft for its trip to the shore. Following a safe and precise recovery, sailors will drain the well deck of water, and the ship will make its way back to Naval Base San Diego.
The Artemis II test flight will confirm the foundational systems and hardware needed for human deep space exploration, taking another step toward missions on the lunar surface and helping the agency prepare for human missions to Mars.

Old Missions, New Discoveries: NASA’s Data Archives Accelerate Science This montage of images taken by the Voyager spacecraft of the planets and four of Jupiter’s moons is set against a false-color picture of the Rosette Nebula with Earth’s moon in the foreground. Archival data from the Voyager missions continue to produce new scientific discoveries. NASA/JPL/ASU
Every NASA mission represents a leap into the unknown, collecting data that pushes the boundaries of human understanding. But the story doesn’t end when the mission concludes. The data carefully preserved in NASA’s archives often finds new purpose decades later, unlocking discoveries that continue to benefit science, technology, and society.
“NASA’s science data is one of our most valuable legacies,” said Kevin Murphy, NASA’s chief science data officer at NASA Headquarters in Washington. “It carries the stories of our missions, the insights of our discoveries, and the potential for future breakthroughs.”

Chief Science Data Officer, NASA’s Science Mission Directorate
NASA’s Science Mission Directorate manages an immense amount of data, spanning astrophysics, biological and physical sciences, Earth science, heliophysics, and planetary science. Currently, NASA’s science data holdings exceed 100 petabytes—enough to store 20 billion photos from the average modern smartphone. This volume is expected to grow significantly with new missions.
This vast amount of data enables new discoveries, connecting scientific observations together in meaningful ways. Over 50% of scientific publications rely on archived data, which NASA provides to millions of commercial, government, and scientific users.
NASA’s five science divisions — Astrophysics, Biological and Physical Sciences, Earth Science, Heliophysics, and Planetary Science — store petabytes’ worth of data in their archives that enable scientists to continually make discoveries. NASA
Managing and stewarding such massive volumes of information requires careful planning, robust infrastructure, and innovative strategies to ensure the data is accessible, secure, and sustainable. Continued support for data storage and cutting-edge technology is key to ensuring future generations of researchers can continue to explore using science data from NASA missions.
Modern technology, such as image processing and artificial intelligence, helps unlock new insights from previous observations. For example, in 1986, NASA’s Voyager 2 spacecraft conducted a historic flyby of Uranus, capturing detailed data on the planet and its environment. Decades later, in the early 2000s, scientists used advanced image processing techniques on this archival data to discover two small moons, Perdita and Cupid, which had gone unnoticed during the initial analysis.
In 2024, researchers revisited this 38-year-old archival data and identified a critical solar wind event that compressed Uranus’s magnetosphere just before the Voyager 2 flyby. This rare event, happening only about four percent of the time, provided unique insights into Uranus’s magnetic field and its interaction with space weather.
The first panel of this artist’s concept depicts how Uranus’s magnetosphere (its protective bubble) was behaving before Voyager 2’s flyby. The second panel shows that an unusual kind of solar weather was happening at the same time as the spacecraft’s flyby, giving scientists a skewed view of Uranus’s magnetosphere. The work enabled by archival Voyager data contributes to scientists’ understanding of this enigmatic planet. NASA/JPL-Caltech
NASA’s Lunar Reconnaissance Orbiter (LRO), launched in 2009, continues to provide data that reshapes our understanding of the Moon. In 2018, scientists analyzing the LRO’s archival data confirmed the presence of water ice in permanently shadowed regions at the Moon’s poles.
In 2024, new studies out of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, showed widespread evidence of water ice within the permanently shadowed regions outside the lunar South Pole, further aiding lunar mission planners. This discovery not only holds implications for lunar exploration but also demonstrates how existing data can yield groundbreaking insights.

NASA’s data archives uncover the secrets of our own planet as well as others. In 2024, archaeologists published a study revealing a “lost” Mayan city in Campeche, Mexico that was previously unknown to the scientific community. The researchers identified the city in archival airborne Earth science data, including a 2013 dataset from NASA Goddard’s LiDAR Hyperspectral & Thermal Imager (G-LiHT) mission.
The Harmonized Landsat and Sentinel-2 (HLS) project provides frequent high-resolution observations of Earth’s surface. Data from HLS has been instrumental in tracking urban growth over time. By analyzing changes in land cover, researchers have used HLS to monitor the expansion of cities and infrastructure development. For example, in rapidly growing metropolitan areas, HLS data has revealed patterns of urban sprawl, helping planners analyze past trends to predict future metropolitan expansion.

Urban Growth in Ontario, California1985-2010
CurtainToggle2-Up
Image Details
Thirty-five miles due east of downtown Los Angeles lies the city of Ontario, California. These natural color Landsat 5 images show the massive growth of the city between 1985 and 2010. The airport, found in the southwest portion of the images, added a number of runways, and large warehousing structures now dominate the once rural areas surrounding the airport. In these images, vegetation is green and brown, while urban structures are bright white and gray. A large dry riverbed in the northeast corner is also bright white, but its nonlinear appearance sets it apart visually. Researchers use archival data from Landsat and other satellites to track the growth of cities like Ontario, CA over time.
These discoveries represent only a fraction of what’s possible. NASA is investing in new technologies to harness the full potential of its data archives, including artificial intelligence (AI) foundation models—open-source AI tools designed to extract new findings from existing science data.
“Our vision is to develop at least one AI model for each NASA scientific discipline, turning decades of legacy data into a treasure trove of discovery,” said Murphy. “By embedding NASA expertise into these tools, we ensure that our scientific data continues to drive innovation across science, industry, and society for generations to come.”
Developed under a collaboration between NASA’s Office of the Chief Science Data Officer, IBM, and universities, these AI models are scientifically validated and adaptable to new datasets, making them invaluable for researchers and industries alike.
“It’s like having a virtual assistant that leverages decades of NASA’s knowledge to make smarter, quicker decisions,” said Murphy.
On June 22, 2013, the Operational Land Imager (OLI) on Landsat 8 captured this false-color image of the East Peak fire burning in southern Colorado near Trinidad. Burned areas appear dark red, while actively burning areas look orange. Dark green areas are forests; light green areas are grasslands. Data from Landsat 8 were used to train the Prithvi artificial intelligence model, which can help detect burn scars. NASA Earth Observatory
The team’s Earth science foundation models—the Prithvi Geospatial model and Prithvi Weather model—analyze vast datasets to monitor Earth’s changing landscape, track weather patterns, and support critical decision-making processes.
Building on this success, the team is now developing a foundation model for heliophysics. This model will unlock new insights about the dynamics of solar activity and space weather, which can affect satellite operations, communication systems, and even power grids on Earth. Additionally, a model designed for the Moon is in progress, aiming to enhance our understanding of lunar resources and environments.
This investment in AI not only shortens the “data-to-discovery” timeline but also ensures that NASA’s data archives continue to drive innovation. From uncovering new planets to informing future exploration and supporting industries on Earth, the possibilities are boundless.
By maintaining extensive archives and embracing cutting-edge technologies, the agency ensures that the data collected today will continue to inspire and inform discoveries far into the future. In doing so, NASA’s legacy science data truly remains the gift that keeps on giving.

A Dramatic Einstein Ring Seen by Webb
One of the first verified predictions of general relativity is the gravitational deflection of starlight. The effect was [first observed in 1919 during a total solar eclipse.](https://briankoberlein.com/post/einstein-and-eddington/) Since stars appear as points of light, the effect is seen as an apparent shift in the position of stars near the eclipse. But the effect happens more generally. If a distant galaxy is obscured by a closer one, some of the distant light is gravitationally lensed around the closer galaxy, giving us a warped and distorted view of the faraway stars. This effect can also magnify the distant galaxy, making its light appear brighter, and we have used this effect to observe some of the most distant stars in the Universe.
