NASA opened applications for new astronauts who could take part in Artemis missions, including work on the moon and development of systems and procedures for eventual crewed missions to Mars. The agency said selected candidates would join its 32 active astronauts and prepare for future missions, including efforts to build a lunar base and lay groundwork for human Mars missions.

Applications are open only to US citizens until 3 December. NASA expects to select its next astronaut candidates by the end of 2027.
