What's happened
NASA has issued a call for applicants to join the 25th astronaut class, with selection due by late 2027 and training to begin in 2028 as the Artemis program intensifies lunar exploration and a future Mars mission.
What's behind the headline?
Brief
NASA is conducting a high-stakes recruitment drive to refill its astronaut corps, reflecting a broader push to accelerate the Artemis program. The agency has historically faced long training pipelines and stringent eligibility, with only a small fraction of applicants succeeding. With the ISS slated for retirement and private space stations set to assume post-ISS human operations, the pool of candidates will shape who wins access to near-term lunar missions and, ultimately, Mars exploration.
What this means for readers
- More opportunities to work in space may emerge, but competition remains intense.
- The transition from ISS to commercial platforms could redefine how crews live, work, and train in orbit.
- The timeline remains tight: final selections by 2027, training by 2028, and lunar landings by Artemis IV.
How we got here
NASA is expanding its astronaut corps as it prepares to accelerate lunar exploration under Artemis, aiming to land crews near the lunar south pole by the mid-2020s and establish a sustained base with public-private partners while transitioning away from the ISS by 2030.

Kennedy Space Center - US space launch site in Florida
The John F. Kennedy Space Center (KSC, originally known as the NASA Launch Operations Center), located on Merritt Island, Florida, is one of the ten field centers of NASA. Since 1968, KSC has been NASA's primary launch center of American spaceflight, research, and technology. Launch operations for the Apollo, Skylab, Space Shuttle and Artemis programs were carried out from Kennedy Space Center Launch Complex 39 and managed by KSC. Located on the east coast of Florida, KSC is adjacent to Cape Canaveral Space Force Station (CCSFS). The management of the two entities work very closely together, share resources, and operate facilities on each other's property. Though the first Apollo flights and all Project Mercury and Project Gemini flights took off from the then-Cape Canaveral Air Force Station, the launches were managed by KSC and its previous organization, the Launch Operations Directorate. Starting with the fourth Gemini mission, the NASA launch control center in Florida (Mercury Control Center, later the Launch Control Center) began handing off control of the vehicle to the Mission Control Center in Houston, shortly after liftoff; in prior missions it held control throughout the entire...
