Acting NASA Administrator Janet Petro and Anke Kaysser-Pyzalla, chair, Executive Board, DLR (German Aerospace Center, or Deutsches Zentrum für Luft- und Raumfahrt), signed an agreement June 16, 2025, to continue a partnership on space medicine research. With this agreement, DLR will provide new radiation sensors aboard the Orion spacecraft during NASA’s Artemis II mission. Scheduled for launch no later than April 2026, Artemis II will mark the first test flight with crew under Artemis.Credit: DLR While attending the Paris Air Show June 16, NASA acting Administrator Janet Petro signed an agreement with DLR (German Aerospace Center, or Deutsches Zentrum für Luft- und Raumfahrt) to continue a partnership in space medicine research. This renewed collaboration builds on previous radiation mitigation efforts for human spaceflight. As NASA advances the Trump-Vance Administration’s goals for exploration on the Moon and Mars, minimizing exposure to space radiation is one of the key areas the agency is working to protect crew on long duration missions.
With this agreement, DLR will leverage its human spaceflight expertise and provide new radiation sensors aboard the Orion spacecraft during NASA’s Artemis II mission, building on previous work in this area during the Artemis I mission. Scheduled for launch no later than April 2026, Artemis II will mark the first test flight with crew under Artemis.
“In keeping with the historic agreements NASA has made with international partners as a part of Artemis, I am pleased to sign a new NASA-DLR joint agreement today, to enable radiation research aboard Artemis II,” said acting NASA Administrator Janet Petro. “The German Aerospace Center has been a valuable partner in Artemis, having previously worked with NASA to test technology critical to our understanding of radiation on humans aboard an Orion spacecraft on Artemis I and providing a CubeSat as part of Artemis II. Following a productive meeting between President Trump and German Chancellor Merz earlier this month, I am excited to build upon our great partnership with Germany.”
During the Artemis II mission’s planned 10-day journey around the Moon and back, four of DLR’s newly developed M-42 extended (M-42 EXT) radiation detectors will be on board, contributing vital data to support astronaut safety. This next-generation device represents a new phase of research as NASA and DLR continue working together to safeguard human health in space.
Under the leadership of President Trump, America’s Artemis campaign has reignited NASA’s ambition, sparking international cooperation and cutting-edge innovation. The continued partnership with DLR and the deployment of their advanced M-42 EXT radiation detectors aboard Artemis II exemplifies how the Trump-Vance Administration is leading a Golden Era of Exploration and Innovation that puts American astronauts on the path to the Moon, Mars, and beyond.
“To develop effective protective measures against the impact of space radiation on the human body, comprehensive and coherent radiation measurements in open space are essential,” says Anke Pagels-Kerp, divisional board member for space at DLR. “At the end of 2022, Artemis I carried 12,000 passive and 16 active detectors inside the Helga and Zohar mannequins, which flew aboard the Orion spacecraft as part of DLR’s MARE project. These provided a valuable dataset – the first continuous radiation measurements ever recorded beyond low Earth orbit. We are now excited to take the next step together with NASA and send our upgraded radiation detectors around the Moon on the Artemis II mission.”
Through the Artemis campaign, the agency will establish a long-term presence on the Moon for scientific exploration with our commercial and international partners, learn how to live and work away from home, and prepare for future human exploration of Mars.

Photo Credit: NASA Four NASA astronauts will participate in a welcome home ceremony at Space Center Houston after recently returning from missions aboard the International Space Station.
NASA astronauts Nick Hague, Suni Williams, Butch Wilmore, and Don Pettit will share highlights from their missions at 6 p.m. CDT Thursday, May 22, during a free, public event at NASA Johnson Space Center’s visitor center. The astronauts also will recognize key mission contributors during an awards ceremony after their presentation.
Williams and Wilmore launched aboard Boeing’s Starliner spacecraft and United Launch Alliance Atlas V rocket on June 5, 2024, from Space Launch Complex 41 as part of NASA’s Boeing Crew Flight Test. The duo arrived at the space station on June 6. In August, NASA announced the uncrewed return of Starliner to Earth and integrated Wilmore and Williams with the Expedition 71/72 crew and a return on Crew-9.
Hague launched Sept. 28, 2024, with Roscosmos cosmonaut Aleksandr Gorbunov aboard a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida as part of NASA’s SpaceX Crew-9 mission. The next day, they docked to the forward-facing port of the station’s Harmony module.
Hague, Gorbunov, Wilmore, and Williams returned to Earth on March 18, 2025, splashing down safely off the coast of Tallahassee, Florida, in the Gulf of America.
Williams and Wilmore traveled 121,347,491 miles during their mission, spent 286 days in space, and completed 4,576 orbits around Earth. Hague and Gorbunov traveled 72,553,920 miles during their mission, spent 171 days in space, and completed 2,736 orbits around Earth. Hague has logged 374 days in space during two missions. It was the third spaceflight for both Williams and Wilmore. Williams has logged 608 total days in space, and Wilmore has logged 464 days.
Pettit launched aboard the Soyuz MS-26 spacecraft on Sept. 11, 2024, alongside Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner. The seven-month research mission as an Expedition 72 flight engineer was the fourth spaceflight of Pettit’s career, completing 3,520 orbits of the Earth and a journey of 93.3 million miles. He has logged a total of 590 days in orbit. Pettit and his crewmembers safely landed in Kazakhstan on April 19, 2025 (April 20, 2025, Kazakhstan time).
The Expedition 72 crew dedicated more than 1,000 combined hours to scientific research and technology demonstrations aboard the International Space Station. Their work included enhancing metal 3D printing capabilities in orbit, exploring the potential of stem cell technology for treating diseases, preparing the first wooden satellite for deployment, and collecting samples from the station’s exterior to examine whether microorganisms can survive in the harsh environment of space. They also conducted studies on plant growth and quality, investigated how fire behaves in microgravity, and advanced life support systems, all aimed at improving the health, safety, and sustainability of future space missions. Pettit also used his spare time and surroundings aboard station to conduct unique experiments and captivate the public with his photography. Expedition 72 captured a record one million photos during the mission, showcasing the unique research and views aboard the orbiting laboratory through astronauts’ eyes.
For more than 24 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge, and conducting critical research for the benefit of humanity and our home planet. Space station research supports the future of human spaceflight as NASA looks toward deep space missions to the Moon under the Artemis campaign and in preparation for future human missions to Mars, as well as expanding commercial opportunities in low Earth orbit and beyond.
