NASA is looking for a new generation of astronauts who could live and work on the Moon ahead of future missions to Mars

NASA has opened applications for a new generation of astronauts who could help build a base on the Moon and prepare for the first crewed missions to Mars. The announcement was made Saturday at the Kennedy Space Center during an air show dedicated to space exploration.

NASA Administrator Jared Isaacman said those selected could walk on the Moon, live and work at the lunar base, and help develop the systems needed for flights to Mars. The U.S. agency intends to send astronauts back to the Moon in 2028, with support from SpaceX and Blue Origin.

Final selection is scheduled for the end of 2027, after which the chosen candidates will begin training for complex missions. NASA selected its most recent class in 2025, accepting 10 astronauts from more than 8,000 candidates.

Applicants must be U.S. citizens and hold a master’s degree in science, technology, engineering or mathematics, medical qualifications, pilot training or relevant doctoral studies. At least three years of professional experience is also required. Pilots must meet additional requirements concerning the number of flight hours. Applications close Thursday, December 3, at 11:59 p.m. Eastern Time.
