The Soyuz MS-26 spacecraft is seen as it lands in a remote area near the town of Zhezkazgan, Kazakhstan with Expedition 72 NASA astronaut Don Pettit, and Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner aboard, April 19, 2025 (April 20, 2025, Kazakhstan time). The trio are returning to Earth after logging 220 days in space as members of Expeditions 71 and 72 aboard the International Space Station.NASA/Bill Ingalls NASA astronaut Don Pettit returned to Earth Saturday, accompanied by Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner, concluding a seven-month science mission aboard the International Space Station.
The trio departed the space station at 5:57 p.m. EDT aboard the Soyuz MS-26 spacecraft before making a safe, parachute-assisted landing at 9:20 p.m. (6:20 a.m. on Sunday, April 20, Kazakhstan time), southeast of Dzhezkazgan, Kazakhstan. Pettit also celebrates his 70th birthday on Sunday, April 20.
Spanning 220 days in space, Pettit and his crewmates orbited the Earth 3,520 times, completing a journey of 93.3 million miles. Pettit, Ovchinin, and Vagner launched and docked to the orbiting laboratory on Sept. 11, 2024.
During his time aboard the space station, Pettit conducted research to enhance in-orbit metal 3D printing capabilities, advance water sanitization technologies, explore plant growth under varying water conditions, and investigate fire behavior in microgravity, all contributing to future space missions. He also used his surroundings aboard station to conduct unique experiments in his spare time and captivate the public with his photography.
This was Pettit’s fourth spaceflight, where he served as a flight engineer for Expeditions 71 and 72. He has logged 590 days in orbit throughout his career. Ovchinin completed his fourth flight, totaling 595 days, and Vagner has earned an overall total of 416 days in space during two spaceflights.
NASA is following its routine postlanding medical checks, the crew will return to the recovery staging area in Karaganda, Kazakhstan. Pettit will then board a NASA plane bound for the agency’s Johnson Space Center in Houston. According to NASA officials at the landing site, Pettit is doing well and in the range of what is expected for him following return to Earth.
For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that are not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a strong low Earth orbit economy, NASA is focusing more resources on deep space missions to the Moon as part of Artemis in preparation for future astronaut missions to Mars.

NASA researchers are sending three air quality monitors to the International Space Station to test them for potential future use on the Moon.Credit: NASA/Sara Lowthian-Hanna As NASA prepares to return to the Moon, studying astronaut health and safety is a top priority. Scientists monitor and analyze every part of the International Space Station crew’s daily life—down to the air they breathe. These studies are helping NASA prepare for long-term human exploration of the Moon and, eventually, Mars.
As part of this effort, NASA’s Glenn Research Center in Cleveland is sending three air quality monitors to the space station to test them for potential future use on the Moon. The monitors are slated to launch on Monday, April 21, aboard the 32nd SpaceX commercial resupply services mission for NASA.
Like our homes here on Earth, the space station gets dusty from skin flakes, clothing fibers, and personal care products like deodorant. Because the station operates in microgravity, particles do not have an opportunity to settle and instead remain floating in the air. Filters aboard the orbiting laboratory collect these particles to ensure the air remains safe and breathable.
Astronauts will face another air quality risk when they work and live on the Moon—lunar dust.
“From Apollo, we know lunar dust can cause irritation when breathed into the lungs,” said Claire Fortenberry, principal investigator, Exploration Aerosol Monitors project, NASA Glenn. “Earth has weather to naturally smooth dust particles down, but there is no atmosphere on the Moon, so lunar dust particles are sharper and craggier than Earth dust. Lunar dust could potentially impact crew health and damage hardware.”
Future space stations and lunar habitats will need monitors capable of measuring lunar dust to ensure air filtration systems are functioning properly. Fortenberry and her team selected commercially available monitors for flight and ground demonstration to evaluate their performance in a spacecraft environment, with the goal of providing a dust monitor for future exploration systems.
NASA Glenn Research Center’s Claire Fortenberry holds a dust sample collected from International Space Station air filters.Credit: NASA/Sara Lowthian-Hanna Glenn is sending three commercial monitors to the space station to test onboard air quality for seven months. All three monitors are small: no bigger than a shoe box. Each one measures a specific property that provides a snapshot of the air quality aboard the station. Researchers will analyze the monitors based on weight, functionality, and ability to accurately measure and identify small concentrations of particles in the air.
The research team will receive data from the space station every two weeks. While those monitors are orbiting Earth, Fortenberry will have three matching monitors at Glenn. Engineers will compare functionality and results from the monitors used in space to those on the ground to verify they are working as expected in microgravity. Additional ground testing will involve dust simulants and smoke.
Air quality monitors like the ones NASA is testing also have Earth-based applications. The monitors are used to investigate smoke plumes from wildfires, haze from urban pollution, indoor pollution from activities like cooking and cleaning, and how virus-containing droplets spread within an enclosed space.
Results from the investigation will help NASA evaluate which monitors could accompany astronauts to the Moon and eventually Mars. NASA will allow the manufacturers to review results and ensure the monitors work as efficiently and effectively as possible. Testing aboard the space station could help companies investigate pollution problems here on Earth and pave the way for future missions to the Red Planet.

NASA commercial resupply missions to the International Space Station deliver scientific investigations in the areas of biology and biotechnology, Earth and space science, physical sciences, and technology development and demonstrations. Cargo resupply from U.S. companies ensures a national capability to deliver scientific research to the space station, significantly increasing NASA’s ability to conduct new investigations aboard humanity’s laboratory in space.

It also evaluates how well the materials reduce joint inflammation and whether they can help regenerate cartilage lost due to arthritis. These materials are less toxic, more stable, and more compatible with living tissues than current drug delivery technologies.
Environmental influences such as gravity can affect the quality of these materials and delivery systems. In microgravity, they are larger and have greater uniformity and structural integrity. This investigation could help identify the best formulations and methods for cost-effective in-space production. These nanomaterials also could be used to create novel systems targeting therapy delivery that improves patient outcomes with fewer side effects.
Helping Plants Grow

Because photosynthesis needs light, which requires spacecraft power to generate, alternatives would reduce energy use.
The investigation also examines whether using supplements increases plant growth on the space station, which has been observed in preflight testing on Earth. In future plant production facilities aboard spacecraft or on celestial bodies, supplements could come from available organic materials such as waste.
Understanding how plants adapt to microgravity could help grow food during long-duration space missions or harsh environments on Earth.

This S-3 supported vital flight research by donating parts to its sister plane, another S3-B Viking that was retired in 2021.Credit: NASA/Jordan Cochran After supporting the center’s research missions for more than a decade, NASA’s S-3B Viking aircraft is moving on from NASA’s Glenn Research Center in Cleveland to begin a new and honorable assignment.
The aircraft is heading to the National POW/MIA Memorial and Museum in Jacksonville, Florida, where it will be on display, honoring all Prisoners of War (POW), those Missing in Action (MIA), and the families who seek the return of their loved ones. The museum gives visitors a place of solace to reflect, learn, and hear stories about America’s POW and MIA service members through exhibits and events.
A team of volunteers, many of whom are veterans, converged to disassemble an S-3B Viking at NASA’s Glenn Research Center in Cleveland so it could be transported by truck to the National Pow/MIA Memorial and Museum in Jacksonville, Florida. Credit: NASA/Lillianne Hammel “We are honored to be part of it,” said JD Demers, chief of Aircraft Operations at NASA Glenn. “Moving the S-3 is a win-win for everybody. The museum gets an aircraft in beautiful shape, and our S-3 gets to continue living a meaningful life.”
Originally designed by Lockheed Martin as an anti-submarine warfare aircraft, NASA’s S-3B Viking will travel south to its new museum home, which is located at the former Naval Air Station Cecil Field where S-3B Vikings once flew. It will be displayed with a plaque recognizing the 54 service members who perished during S-3 flight missions.

Behind the scenes, this S-3 supported vital NASA flight research by donating parts to its sister plane, another S3-B Viking that was retired in 2021. Through the donation of its parts, the S-3 contributed to communications research in advanced air mobility and monitoring of algal bloom growth in Lake Erie.
“Having this aircraft added an extra 10 years of life to its sister plane,” Demers said. “Those 10 years were vital for research. This plane allowed us to keep flying that aircraft after the Navy retired the S-3B Vikings in 2009. We wouldn’t have been able to find parts.”

This is an artist’s impression of a magnetar, a special type of neutron star with an incredibly strong magnetic field. Credits:
ESA Researchers using NASA’s Hubble Space Telescope have discovered the magnetar called SGR 0501+4516 is traversing our galaxy from an unknown place of origin. Researchers say that this runaway magnetar is the likeliest candidate in our Milky Way galaxy for a magnetar that was not born in a supernova explosion as initially predicted. It is so strange it might even offer clues to the mechanism behind events known as fast radio bursts.
“Magnetars are neutron stars — the dead remnants of stars — composed entirely of neutrons. What makes magnetars unique is their extreme magnetic fields,” said Ashley Chrimes, lead author of the discovery paper published in the April 15 journal Astronomy & Astrophysics. Chrimes is a European Space Agency Research Fellow at the European Space Research and Technology Center in the Netherlands.
Magnetars have comic-book-hero superpowers. A magnetar has a magnetic field about a trillion times more powerful than Earth’s magnetosphere. If a magnetar flew by Earth at half the Moon’s distance, its intense field would wipe out every credit card on our planet. If a human got within 600 miles, the magnetar would become a proverbial sci-fi death-ray, ripping apart every atom inside the body.
The magnetar’s strangeness was identified with the help of Hubble’s sensitive instruments as well as precise benchmarks from ESA’s (European Space Agency) Gaia spacecraft.
Initially, the mysterious magnetar was discovered in 2008 when NASA’s Swift Observatory spotted brief, intense flashes of gamma rays from the outskirts of the Milky Way. The source, which turned out to be one of only about 30 known magnetars in the Milky Way, was dubbed SGR 0501+4516.
This is an artist’s impression of a magnetar, which is a special type of neutron star with an incredibly strong magnetic field. Neutron stars are some of the most compact and extreme objects in the universe. These stars typically pack more than the mass of the Sun into a sphere of neutrons about 12 miles across. The neutron star is depicted as a white-blueish sphere. The magnetic field is shown as filaments streaming out from its polar regions. Illustration: ESA Because magnetars are neutron stars, the natural explanation for their formation is that they are born in supernovae, when a star explodes and can collapse down to an ultra-dense neutron star. This appeared to be the case for SGR 0501+4516, which is located close to a supernova remnant called HB9. The separation between the magnetar and the center of the supernova remnant on the sky is just 80 arcminutes, or slightly wider than your pinky finger when viewed at the end of your outstretched arm.
But a decade-long study with Hubble cast doubt on the magnetar’s birthplace. After initial observations with ground-based telescopes shortly after SGR 0501+4516’s discovery, researchers used Hubble’s exquisite sensitivity and steady pointing to spot the magnetar’s faint infrared glow in 2010, 2012, and 2020. Each of these images was aligned to a reference frame defined by observations from the Gaia spacecraft, which has crafted an extraordinarily precise three-dimensional map of nearly two billion stars in the Milky Way. This method revealed the subtle motion of the magnetar as it traversed the sky.
“All of this movement we measure is smaller than a single pixel of a Hubble image,” said co-investigator Joe Lyman of the University of Warwick, United Kingdom. “Being able to robustly perform such measurements really is a testament to the long-term stability of Hubble.”
By tracking the magnetar’s position, the team was able to measure the object’s apparent motion across the sky. Both the speed and direction of SGR 0501+4516’s movement showed that the magnetar could not be associated with the nearby supernova remnant. Tracing the magnetar’s trajectory thousands of years into the past showed that there were no other supernova remnants or massive star clusters with which it could be associated.
If SGR 0501+4516 was not born in a supernova, the magnetar must either be older than its estimated 20,000-year age, or it may have formed in another way. Magnetars may also be able to form through the merger of two lower-mass neutron stars or through a process called accretion-induced collapse. Accretion-induced collapse requires a binary star system containing a white dwarf: the core of a dead Sun-like star. If the white dwarf pulls in gas from its companion, it can grow too massive to support itself, leading to an explosion — or possibly the creation of a magnetar.
“Normally, this scenario leads to the ignition of nuclear reactions, and the white dwarf exploding, leaving nothing behind. But it has been theorized that under certain conditions, the white dwarf can instead collapse into a neutron star. We think this might be how SGR 0501 was born,” added Andrew Levan of Radboud University in the Netherlands and the University of Warwick in the United Kingdom.
Understanding Fast Radio Bursts
SGR 0501+4516 is currently the best candidate for a magnetar in our galaxy that may have formed through a merger or accretion-induced collapse. Magnetars that form through accretion-induced collapse could provide an explanation for some of the mysterious fast radio bursts, which are brief but powerful flashes of radio waves. In particular, this scenario may explain the origin of fast radio bursts that emerge from stellar populations too ancient to have recently birthed stars massive enough to explode as supernovae.
“Magnetar birth rates and formation scenarios are among the most pressing questions in high-energy astrophysics, with implications for many of the universe’s most powerful transient events, such as gamma-ray bursts, super-luminous supernovae, and fast radio bursts,” said Nanda Rea of the Institute of Space Sciences in Barcelona, Spain.
The research team has further Hubble observations planned to study the origins of other magnetars in the Milky Way, helping to understand how these extreme magnetic objects form.
The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.
