The U.S. space agency, NASA, has announced it is accepting applications for its next class of astronauts. This recruitment drive is a crucial step as NASA prepares to return humans to the Moon, establish a sustained lunar presence, and lay the groundwork for future crewed missions to Mars.
According to NASA’s November 7th announcement, applications will remain open until 11:59 p.m. Eastern Standard Time on December 3rd. The agency anticipates announcing its final selections in late 2027, with successful candidates commencing their intensive astronaut training shortly thereafter.
Who Can Apply to Become a NASA Astronaut?
The recruitment process is open exclusively to U.S. citizens who fulfill NASA’s stringent educational, professional, and medical requirements. Applicants must possess a master’s degree in a science, technology, engineering, or mathematics (STEM) field from an accredited institution. Acceptable fields include engineering, biological science, physical science, or computer science.
NASA also recognizes certain alternative qualifications. These include at least two years of doctoral-level study in a relevant technical field, specific medical qualifications, or the completion of a recognized test pilot school program by July 2027. Candidates qualifying via the test pilot route must also hold a bachelor’s degree in a relevant STEM discipline.
Beyond academic credentials, applicants need a minimum of three years of relevant professional experience acquired after completing their qualifying degree. Pilots can satisfy this requirement through specified flight hours, depending on their aircraft experience. Medical residency training may also count if completed by July 2027.
All candidates must pass NASA’s long-duration astronaut flight physical and demonstrate exceptional leadership, communication, and teamwork abilities.
Training and Future Space Missions
Selected candidates will undergo rigorous training at NASA’s Johnson Space Center in Houston, Texas. The comprehensive program covers essential skills for demanding space missions, including spacewalking, lunar geology, spacecraft operations, and high-performance aircraft piloting.
NASA Administrator Jared Isaacman stated that the selected astronauts could eventually walk on the Moon, live and work at a lunar base, and contribute to developing the technologies and operational capabilities necessary to send humans to Mars. He emphasized that these ambitious missions demand technical expertise, sound judgment, teamwork, and immense courage.
The next astronaut class is expected to play a vital role in supporting NASA’s Artemis program, which aims to expand human exploration of the Moon, with a particular focus on its lunar South Pole. The agency intends to leverage the experience gained through lunar exploration to prepare for future crewed missions to Mars.
A Legacy of Exploration
NASA last opened astronaut applications in 2024, attracting over 8,000 applicants, from which ten candidates were selected in 2025. Since the inception of its astronaut program, NASA has selected 370 astronaut candidates, with 32 active astronauts currently in its corps.
Scott Tingle, NASA’s chief astronaut and chair of the Astronaut Selection Board, remarked that becoming an astronaut is more than just a career opportunity; it offers candidates a chance to contribute to discoveries that could shape humanity’s future in space.
