Bringing Astronauts Home Safely, Space Station Milestones
America brought Crew-9 safely home. NASA astronauts Butch Wilmore, Suni Williams, and Nick Hague, along with Roscosmos cosmonaut Aleksandr Gorbunov, returned to Earth after a successful mission aboard the International Space Station, splashing down in the Gulf of America. Their safe return reflects America’s unwavering commitment to the agency’s astronauts and mission success. A new, American-led mission launched to space. The agency’s Crew-10 mission is currently aboard the space station, with NASA astronauts Anne McClain and Nichole Ayers, joined by international partners from Japan and Russia. NASA continues to demonstrate American leadership and the power of space diplomacy as we maintain a continuous human presence in orbit. The agency welcomed home NASA astronaut Don Pettit, concluding a seven-month science mission aboard the orbiting laboratory. Pettit landed at 6:20 a.m. Kazakhstan time, April 20 on his 70th birthday, making him NASA’s oldest active astronaut and the third oldest person to reach orbit. NASA astronaut Jonny Kim launched and arrived safely at the International Space Station, marking the start of his first space mission. Over eight months, he’ll lead groundbreaking research that advances science and improves life on Earth, proving once again that Americans are built to lead in space. The four members of the agency’s SpaceX Crew-11, NASA astronauts Zena Cardman and Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov were named by NASA. Launching no earlier than July 2025, this mission continues America’s leadership in long-duration human spaceflight while strengthening critical global partnerships. NASA announced Chris Williams will launch in November 2025 for his first spaceflight. His upcoming mission underscores the pipeline of American talent ready to explore space and expand our presence beyond Earth. NASA is inviting U.S. industry to propose two new private astronaut missions to the space station in 2026 and 2027 – building toward a future where American companies sustain a continuous human presence in space and advance our national space economy. NASA and SpaceX launched the 32nd Commercial Resupply Services mission, delivering 6,700 pounds of cargo to the International Space Station. These investments in science and technology continue to strengthen America’s leadership in low Earth orbit. The payload supports cutting-edge research, including:New maneuvers for free-flying robots An advanced air quality monitoring system Two atomic clocks to explore relativity and ultra-precise timekeeping Sending Humans to Moon, Mars
Teams began hot fire testing the first of three 12-kW Solar Electric Propulsion (SEP) thrusters. These high-efficiency thrusters are a cornerstone of next-generation spaceflight, as they offer greater fuel economy and mission flexibility than traditional chemical propulsion, making them an asset for long-duration missions to the Moon, Mars, and beyond. For Mars in particular, SEP enables three key elements required for success:Sustained cargo transport Orbital maneuvering Transit operations NASA completed the fourth Entry Descent and Landing technology test in three months, accelerating innovation to achieve precision landings on Mars’ thin atmosphere and rugged terrain. NASA’s Deep Space Optical Communications experiment aboard Psyche broke new ground, enabling the high-bandwidth connections vital for communications with crewed missions to Mars. Firefly Aerospace’s Blue Ghost Mission One successfully delivered 10 NASA payloads to the Moon, advancing landing, autonomy, and data collection skills for Mars missions. Intuitive Machines’ IM-2 mission achieved the southernmost lunar landing, collecting critical data from challenging terrain to inform Mars exploration strategies. NASA cameras aboard Firefly’s Blue Ghost lander captured unprecedented footage of engine plume-surface interactions, offering vital data for designing safer landings on the Moon and Mars. The agency’s Stereo Cameras for Lunar Plume-Surface Studies (SCALPSS) 1.1 aboard Blue Ghost collected more than 9,000 images of lunar descent, providing insights on lander impacts and terrain interaction to guide future spacecraft design. New SCALPSS hardware delivered for Blue Origin’s Blue Mark 1 mission also is enhancing lunar landing models, helping build precision landing systems for the Moon and Mars. The LuGRE (Lunar Global Navigation Satellite System Receiver Experiment) on Blue Ghost acquired Earth navigation signals from the Moon, advancing autonomous positioning systems crucial for lunar and Mars operations. The Electrodynamic Dust Shield successfully cleared lunar dust, demonstrating a critical technology for protecting equipment on the Moon and Mars. Astronauts aboard the space station conducted studies to advance understanding of how to keep crews healthy on long-duration Mars missions. NASA’s Moon to Mars Architecture Workshop gathered industry, academic, and international partners to refine exploration plans and identify collaboration opportunities. Artemis Milestones
NASA completed stacking the twin solid rocket boosters for Artemis II, the mission that will send American astronauts around the Moon for the first time in more than 50 years. This is a powerful step toward returning our nation to deep space. At NASA’s Kennedy Space Center in Florida, teams joined the core stage with the solid rocket boosters inside the Vehicle Assembly Building. Engineers lifted the launch vehicle stage adapter atop the SLS (Space Launch System) core stage, connecting key systems that will soon power NASA’s return to the Moon. Teams received the Interim Cryogenic Propulsion Stage and moved the SLS core stage into the transfer aisle, clearing another milestone as the agency prepares to fully integrate America’s most powerful rocket. NASA attached the solar array wings that will help power the Orion spacecraft on its journey around the Moon, laying the groundwork for humanity’s next giant leap. Technicians installed the protective fairings on Orion’s service module to shield the spacecraft during its intense launch and ascent phase, as NASA prepares to send astronauts farther than any have gone in more than half a century. The agency’s next-generation mobile launcher continues to take shape, with the sixth of 10 massive modules being installed. This structure will carry future Artemis rockets to the launch pad. NASA and the Department of Defense teamed up aboard the USS Somerset for Artemis II recovery training, ensuring the agency and its partners are ready to safely retrieve Artemis astronauts after their historic mission around the Moon. NASA unveiled the Artemis II mission patch. The patch designates the mission as “AII,” signifying not only the second major flight of the Artemis campaign but also an endeavor of discovery that seeks to explore for all and by all. America First in Space
NASA announced the first major science results from asteroid Bennu, revealing ingredients essential for life, a discovery made possible by U.S. leadership in planetary science through the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) mission. The team found salty brines, 14 of the 20 amino acids used to make proteins, and all five DNA nucleobases, suggesting that the conditions and ingredients for life were widespread in our early solar system. And this is just the beginning – these results were from analysis of only 0.06% of the sample. NASA was named one of TIME’s Best Companies for Future Leaders, underscoring the agency’s role in cultivating the next generation of American innovators. NASA awarded contracts to U.S. industry supporting Earth science missions, furthering our understanding of the planet while strengthening America’s industrial base. As part of the Air Traffic Management-Exploration project, NASA supported Boeing’s test of digital and autonomous taxiing with a Cessna Caravan at Moffett Federal Airfield. The test used real-time simulations from the agency’s Future Flight Central to gather data that will help Boeing refine its systems and safely integrate advanced technologies into national airspace, demonstrating American aviation leadership. NASA successfully completed its automated space traffic coordination objectives between the agency’s four Starling spacecraft and SpaceX’s Starlink constellation. Teams demonstrated four risk mitigation maneuvers, autonomously resolving close approaches between two spacecraft with different owner/operators. In collaboration with the National Institute of Aeronautics, NASA selected eight finalists in a university competition aimed at designing innovative aviation solutions that can help the agriculture industry. NASA’s Gateways to Blue Skies seeks ways to apply American aircraft and aviation technology to enhance the productivity, efficiency, and resiliency of American farms. In Houston, United Airlines pilots successfully conducted operational tests of NASA-developed technologies designed to reduce flight delays. Using technologies from the Air Traffic Management Exploration project, pilots flew efficient re-routes, avoiding airspace with bad weather upon departure. United plans to expand the use of these capabilities, another example of how NASA innovations benefit all humanity. On March 11, NASA’s newest astrophysics observatory, SPHEREx, launched on its journey to answer fundamental questions about our universe, thanks to the dedication and expertise of the agency’s team. Riding aboard a SpaceX Falcon 9 from Vandenberg Space Force Base, SPHEREx will scan the entire sky to study how galaxies formed, search for the building blocks of life, and look back to the universe’s earliest moments. After launch, SPHEREx turned on its detectors, and everything is performing as expected. Also onboard were four small satellites for NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission, which will help scientists understand how the Sun’s outer atmosphere becomes solar wind. These missions reflect the best of the agency – pushing the boundaries of discovery and expanding our understanding of the cosmos. On March 14, NASA’s EZIE (Electrojet Zeeman Imaging Explorer) mission launched from Vandenberg Space Force Base. This trio of small satellites will study auroral electrojets, or intense electric currents flowing high above Earth’s poles, helping the agency better understand space weather and its effects on our planet. The mission has taken its first measurements, demonstrating that the spacecraft and onboard instrument are working as expected. The X-59 quiet supersonic aircraft cleared another hurdle on its way to first flight. The team successfully completed an engine speed hold test, confirming the “cruise control” system functions as designed. NASA researchers successfully tested a prototype that could help responders fight and monitor wildfires, even in low-visibility conditions. The Portable Airspace Management System, developed by NASA’s Advanced Capabilities for Emergency Response Operations project, safely coordinated simulated operations involving drones and other aircraft, tackling a major challenge for those on the front lines. This is just one example of how NASA’s innovation is making a difference where it’s needed most. NASA’s Parker Solar Probe completed its 23rd close approach to the Sun, coming within 3.8 million miles of the solar surface while traveling at 430,000 miles per hour – matching its own records for distance and speed. That same day, Parker Solar Probe was awarded the prestigious Collier Trophy, a well-earned recognition for its groundbreaking contributions to heliophysics. In response to severe weather that impacted more than 10 states earlier this month, the NASA Disasters Response Coordination System activated to support national partners. NASA worked closely with the National Weather Service and the Federal Emergency Management Agency serving the central and southeastern U.S. to provide satellite data and expertise that help communities better prepare, respond, and recover. As an example of how NASA’s research today is shaping the transportation of tomorrow, the agency’s aeronautics engineers began a flight test campaign focused on safely integrating air taxis into the national airspace. Using a Joby Aviation demonstrator aircraft, engineers are helping standardize flight test maneuvers, improving tools to assist with collision avoidance and landing operations, and ensuring safe and efficient air taxis operations in various weather conditions. NASA premiered “Planetary Defenders,” a new documentary that follows the dedicated team behind asteroid detection and planetary defense. The film debuted at an event at the agency’s headquarters with digital creators, interagency and international partners, and now is streaming on NASA+, YouTube, and X. In its first 24 hours, it saw 25,000 views on YouTube – 75% above average – and reached 4 million impressions on X. Finland became the 53rd nation to sign the Artemis Accords, reaffirming its commitment to the peaceful, transparent, and responsible exploration of space. This milestone underscores the growing global coalition led by the United States to establish a sustainable and cooperative presence beyond Earth. In Dhaka, Bangladesh, NASA welcomed a new signatory to the Artemis Accords. Bangladesh became the 54th nation to commit to the peaceful, safe, and responsible exploration of space. It’s a milestone that reflects our shared values and growing global momentum, reaffirming the United States’ leadership in building a global coalition for peaceful space exploration. At NASA’s Armstrong Flight Research Center in Edwards, California, engineers conducted calibration flights for a new shock-sensing probe that will support future flight tests of the X-59 quiet supersonic demonstrator. Mounted on a research F-15D that will follow the X-59 closely in flight, the probe will gather data on the shock waves the X-59 generates, providing important data about its ability to fly faster than sound, but produce only a quiet thump. In its second asteroid encounter, Lucy flew by the asteroid Donaldjohanson and gave NASA a close look at a uniquely shaped fragment dating back 150 million years – an impressive performance ahead of its main mission target in 2027. A celebration of decades of discovery, NASA’s Hubble Space Telescope celebrated its 35th anniversary with new observations ranging from nearby solar system objects to distant galaxies – proof that Hubble continues to inspire wonder and advance our understanding of the universe. The SPHEREx team rang the closing bell at the New York Stock Exchange, spotlighting NASA’s newest space telescope and its bold mission to explore the origins of the universe. NASA received six Webby Awards and six People’s Voice Awards across platforms – recognition of America’s excellence in digital engagement and public communication. The NASA Electric Aircraft Testbed and Advanced Air Transport Technology project concluded testing of a 2.5-megawatt Wright Electric motor designed to eventually serve large aircraft. The testing used the project’s capabilities to simulate altitude conditions of up to 40,000 feet while the electric motor, the most powerful tested so far at the facility, ran at both full voltage and partial power. NASA partnered with the Department of Energy on the tests. U.S. entities can now request the Glenn Icing Computational Environment (GlennICE) tool from the NASA Software Catalog and discover solutions to icing challenges for novel engine and aircraft designs. A 3D computational tool, GlennICE allows engineers to integrate icing-related considerations earlier in the aircraft design process and enable safer, more efficient designs while saving costs in the design process.

This artist’s concept depicts a magnetar – a type of neutron star with a strong magnetic field – losing material into space. Shown as thin green lines, the magnetic field lines influence the movement of charged material around the magnetar. NASA/JPL-Caltech Since the big bang, the early universe had hydrogen, helium, and a scant amount of lithium. Later, some heavier elements, including iron, were forged in stars. But one of the biggest mysteries in astrophysics is: How did the first elements heavier than iron, such as gold, get created and distributed throughout the universe?
“It’s a pretty fundamental question in terms of the origin of complex matter in the universe,” said Anirudh Patel, a doctoral student at Columbia University in New York. “It’s a fun puzzle that hasn’t actually been solved.”
Patel led a study using 20-year-old archival data from NASA and ESA telescopes that finds evidence for a surprising source of a large amount of these heavy elements: flares from highly magnetized neutron stars, called magnetars. The study is published in The Astrophysical Journal Letters.
Study authors estimate that magnetar giant flares could contribute up to 10% of the total abundance of elements heavier than iron in the galaxy. Since magnetars existed relatively early in the history of the universe, the first gold could have been made this way.
“It’s answering one of the questions of the century and solving a mystery using archival data that had been nearly forgotten,” said Eric Burns, study co-author and astrophysicist at Louisiana State University in Baton Rouge.
How could gold be made at a magnetar?
Neutron stars are the collapsed cores of stars that have exploded. They are so dense that one teaspoon of neutron star material, on Earth, would weigh as much as a billion tons. A magnetar is a neutron star with an extremely powerful magnetic field.
On rare occasions, magnetars release an enormous amount of high-energy radiation when they undergo “starquakes,” which, like earthquakes, fracture the neutron star’s crust. Starquakes may also be associated with powerful bursts of radiation called magnetar giant flares, which can even affect Earth’s atmosphere. Only three magnetar giant flares have been observed in the Milky Way and the nearby Large Magellanic Cloud, and seven outside.
Patel and colleagues, including his advisor Brian Metzger, professor at Columbia University and senior research scientist at the Flatiron Institute in New York, have been thinking about how radiation from giant flares could correspond to heavy elements forming there. This would happen through a “rapid process” of neutrons forging lighter atomic nuclei into heavier ones.
Protons define the element’s identity on the periodic table: hydrogen has one proton, helium has two, lithium has three, and so on. Atoms also have neutrons which do not affect identity, but do add mass. Sometimes when an atom captures an extra neutron the atom becomes unstable and a nuclear decay process happens that converts a neutron into a proton, moving the atom forward on the periodic table. This is how, for example, a gold atom could take on an extra neutron and then transform into mercury.
In the unique environment of a disrupted neutron star, in which the density of neutrons is extremely high, something even stranger happens: single atoms can rapidly capture so many neutrons that they undergo multiple decays, leading to the creation of a much heavier element like uranium.
When astronomers observed the collision of two neutron stars in 2017 using NASA telescopes and the Laser Interferomete Gravitational wave Observatory (LIGO), and numerous telescopes on the ground and in space that followed up the initial discovery, they confirmed that this event could have created gold, platinum, and other heavy elements. But neutron star mergers happen too late in the universe’s history to explain the earliest gold and other heavy elements. Recent research by co-authors of the new study — Jakub Cehula of Charles University in Prague, Todd Thompson of The Ohio State University, and Metzger — has found that magnetar flares can heat and eject neutron star crustal material at high speeds, making them a potential source.

At first, Metzger and colleagues thought that the signature from the creation and distribution of heavy elements at a magnetar would appear in the visible and ultraviolet light, and published their predictions. But Burns in Louisiana wondered if there could be a gamma-ray signal bright enough to be detected, too. He asked Metzger and Patel to check, and they found that there could be such a signature.
“At some point, we said, ‘OK, we should ask the observers if they had seen any,’” Metzger said.
Burns looked up the gamma ray data from the last giant flare that has been observed, which was in December 2004. He realized that while scientists had explained the beginning of the outburst, they had also identified a smaller signal from the magnetar, in data from ESA (European Space Agency)’s INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL), a recently retired mission with NASA contributions. “It was noted at the time, but nobody had any conception of what it could be,” Burns said.
Metzger remembers that Burns thought he and Patel were “pulling his leg” because the prediction from their team’s model so closely matched the mystery signal in the 2004 data. In other words, the gamma ray signal detected over 20 years ago corresponded to what it should look like when heavy elements are created and then distributed in a magnetar giant flare.
Patel was so excited, “I wasn’t thinking about anything else for the next week or two. It was the only thing on my mind,” he said.
Researchers supported their conclusion using data from two NASA heliophysics missions: the retired RHESSI (Reuven Ramaty High Energy Solar Spectroscopic Imager) and the ongoing NASA’s Wind satellite, which had also observed the magnetar giant flare. Other collaborators on the new study included Jared Goldberg at the Flatiron Institute.
Next steps in the magnetar gold rush
NASA’s forthcoming COSI (Compton Spectrometer and Imager) mission can follow up on these results. A wide-field gamma ray telescope, COSI is expected to launch in 2027 and will study energetic phenomena in the cosmos, such as magnetar giant flares. COSI will be able to identify individual elements created in these events, providing a new advancement in understanding the origin of the elements. It is one of many telescopes that can work together to look for “transient” changes across the universe.
Researchers will also follow up on other archival data to see if other secrets are hiding in observations of other magnetar giant flares.
“It very cool to think about how some of the stuff in my phone or my laptop was forged in this extreme explosion of the course of our galaxy’s history,” Patel said.

Video: 00:02:01 ESA’s state-of-the-art Biomass satellite has launched aboard a Vega-C rocket from Europe’s Spaceport in French Guiana. The rocket lifted off on 29 April 2025 at 11:15 CEST (06:15 local time).
In orbit, this latest Earth Explorer mission will provide vital insights into the health and dynamics of the world’s forests, revealing how they are changing over time and, critically, enhancing our understanding of their role in the global carbon cycle. It is the first satellite to carry a fully polarimetric P-band synthetic aperture radar for interferometric imaging. Thanks to the long wavelength of P-band, around 70 cm, the radar signal can slice through the whole forest layer to measure the ‘biomass’, meaning the woody trunks, branches and stems, which is where trees store most of their carbon.
Vega-C is the evolution of the Vega family of rockets and delivers increased performance, greater payload volume and improved competitiveness.

Wolk The Cygnus Loop, also known as the Veil Nebula, is a supernova remnant – the remains of the explosive death of a massive star. Studying images like these leads to discovery, but NASA’s Chandra X-ray Observatory provides another way to experience this data: three-dimensional (3D) models that allow people to explore – and print – examples of stars in the early and end stages of their lives.
The 3D model of the Cygnus Loop is the result of a simulation describing the interaction of a blast wave from the explosion with an isolated cloud of the interstellar medium (that is, dust and gas in between the stars). Chandra sees the blast wave and other material that has been heated to millions of degrees. These 3D models are based on state-of-the-art theoretical models, computational algorithms, and observations from space-based telescopes like Chandra that give us accurate pictures of these cosmic objects and how they evolve over time.
