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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s C-130, now under new ownership, sits ready for its final departure from NASA’s Wallops Flight Facility in Virginia, on Friday, April 18, 2025. NASA/Garon Clark NASA’s C-130 Hercules, fondly known as the Herc, went wheels up at 9:45 a.m., Friday, April 18, as it departed from its decade-long home at NASA’s Wallops Flight Facility in Virginia, for the final time. The aircraft is embarking on a new adventure to serve and protect in the state of California where it is now under the ownership of the California Department of Forestry and Fire Protection (CAL FIRE).
The transition of the C-130 to CAL FIRE is part of a long-running, NASA-wide aircraft enterprise-management activity to consolidate the aircraft fleet and achieve greater operational efficiencies while reducing the agency’s infrastructure footprint.
The C-130 Hercules takes off for the final time from NASA’s Wallops Flight Facility in Virginia.NASA/Garon Clark “Our C-130 and the team behind it has served with great distinction over the past decade,” said David L. Pierce, Wallops Flight Facility director. “While our time with this amazing airframe has come to a close, I’m happy to see it continue serving the nation in this new capacity with CAL FIRE.”
The research and cargo aircraft, built in 1986, was acquired by NASA in 2015. Over the past decade, the C-130 supported the agency’s airborne scientific research, provided logistics support and movement of agency cargo, and supported technology demonstration missions. The aircraft logged approximately 1,820 flight hours in support of missions across the world during its time with the agency.
Additional aircraft housed at NASA Wallops will be relocated to NASA’s Langley Research Center in Hampton, Virginia, in the coming months.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
One of several NASA distributed sensing ground nodes is set up in the foreground while an experimental air taxi aircraft owned by Joby Aviation sits in the background near NASA’s Armstrong Flight Research Center in Edwards, California, on March 12, 2025. NASA is collecting information during this study to help advance future air taxi flights, especially those occurring in cities, to track aircraft moving through traffic corridors and around landing zones.NASA/Genaro Vavuris NASA engineers began using a network of ground sensors in March to collect data from an experimental air taxi to evaluate how to safely integrate such vehicles into airspace above cities – in all kinds of weather.
Researchers will use the campaign to help improve tools to assist with collision avoidance and landing operations and ensure safe and efficient air taxi operations in various weather conditions.
For years, NASA has looked at how wind shaped by terrain, including buildings in urban areas, can affect new types of aircraft. The latest test, which is gathering data from a Joby Aviation demonstrator aircraft, looks at another kind of wind – that which is generated by the aircraft themselves.
Joby flew its air taxi demonstrator over NASA’s ground sensor array near the agency’s Armstrong Flight Research Center in Edwards, California producing air flow data. The Joby aircraft has six rotors that allow for vertical takeoffs and landings, and tilt to provide lift in flight. Researchers focused on the air pushed by the propellers, which rolls into turbulent, circular patterns of wind.
NASA aeronautical meteorologist Luke Bard adjusts one of several wind lidar (light detection and ranging) sensors near NASA’s Armstrong Flight Research Center in Edwards, California, on March 12, 2025, in preparation to collect data from Joby Aviation’s experimental air taxi aircraft. NASA is collecting information during this study to help advance weather-tolerant air taxi operations for the entire industryNASA/Genaro Vavuris This rolling wind can affect the aircraft’s performance, especially when it’s close to the ground, as well as others flying in the vicinity and people on the ground. Such wind turbulence is difficult to measure, so NASA enhanced its sensors with a new type of lidar – a system that uses lasers to measure precise distances – and that can map out the shapes of wind features.
“The design of this new type of aircraft, paired with the NASA lidar technology during this study, warrants a better understanding of possible wind and turbulence effects that can influence safe and efficient flights,” said Grady Koch, lead for this research effort, from NASA’s Langley Research Center in Hampton, Virginia.
Data to Improve Aircraft Tracking
NASA also set up a second array of ground nodes including radar, cameras, and microphones in the same location as the sensors to provide additional data on the aircraft. These nodes will collect tracking data during routine flights for several months.
The agency will use the data gathered from these ground nodes to demonstrate the tracking capabilities and functions of its “distributed sensing” technology, which involves embedding multiple sensors in an area where aircraft are operating.
One of multiple NASA distributed sensing ground nodes is set up in the foreground while an experimental air taxi aircraft owned by Joby Aviation hovers in the background near NASA’s Armstrong Flight Research Center in Edwards, California, on March 12, 2025. NASA is collecting information during this study to help advance future air taxi flights, especially those occurring in cities, to track aircraft moving through traffic corridors and around landing zones.NASA/Genaro Vavuris This technology will be important for future air taxi flights, especially those occurring in cities by tracking aircraft moving through traffic corridors and around landing zones. Distributed sensing has the potential to enhance collision avoidance systems, air traffic management, ground-based landing sensors, and more.
“Our early work on a distributed network of sensors, and through this study, gives us the opportunity to test new technologies that can someday assist in airspace monitoring and collision avoidance above cities,” said George Gorospe, lead for this effort from NASA’s Ames Research Center in California’s Silicon Valley.
Using this data from an experimental air taxi aircraft, NASA will further develop the technology needed to help create safer air taxi flights in high-traffic areas. Both of these efforts will benefit the companies working to bring air taxis and drones safely into the airspace.
The work is led by NASA’s Transformational Tools and Technologies and Convergent Aeronautics Solutions projects under the Transformative Aeronautics Concepts program in support of NASA’s Advanced Air Mobility mission. NASA’s Advanced Air Mobility mission seeks to deliver data to guide the industry’s development of electric air taxis and drones.
