NASA expands flight slots for private astronauts aboard ISS

Los Angeles CA (SPX) Apr 03, 2025

NASA is inviting proposals for two upcoming private astronaut missions to the International Space Station, with launches planned for 2026 and 2027. The initiative is part of the agency's broader strategy to foster a robust commercial presence in low Earth orbit and expand access to space for American companies.

"We are in an incredible time for human spaceflight, with more opportunities to access space and grow a thriving commercial economy in low Earth orbit," said Dana Weigel, program manager for the International Space Station at NASA's Johnson Space Center in Houston.

Weigel emphasized NASA's role in guiding the private sector through its decades of expertise in crew training, mission operations, and orbital research. "NASA remains committed to supporting this expansion by leveraging our decades of expertise to help industry gain the experience needed to train and manage crews, conduct research, and develop future destinations. Private astronaut missions are a key part of this effort, providing companies with hands-on opportunities to refine their capabilities and build partnerships that will shape the future of low Earth orbit."

The planned flights will mark the fifth and sixth private astronaut missions facilitated by NASA. The first three were carried out by Axiom Space in April 2022, May 2023, and January 2024. A fourth is scheduled for no earlier than May 2025.

Each new mission may remain docked at the ISS for a maximum of 14 days, depending on overall traffic to the station and the scheduling of onboard activities. All missions must be organized by a U.S.-based company using U.S. transportation systems that comply with NASA's safety and integration protocols for visiting spacecraft. Details are outlined in Focus Area 4A of NASA Research Announcement NNJ13ZBG001N.

SpaceX to launch private astronauts on first crewed polar orbit
Cape Canaveral (AFP) Mar 31, 2025
SpaceX is set to launch the first human spaceflight directly over Earth's polar regions on Monday - a days-long, privately funded orbital mission involving four astronauts. Named "Fram2" after the famed Norwegian ship built in the 19th century for Arctic and Antarctic expeditions, the mission will feature a range of experiments including taking the first X-ray in space and growing mushrooms in microgravity. It's hoped that the research will support future long-duration space travel to Mars. ... read more
