NASA Opens Applications for New Astronaut Class to Support Lunar Missions

NASA has launched a recruitment drive for its next class of astronauts, targeting U.S. citizens who can meet a stringent set of qualifications. Applications must be submitted through the agency’s portal by 11:59 p.m. Eastern Time on Dec. 3. Successful candidates will receive an annual salary of $164,395 and will be required to relocate to Houston, Texas, to work at the Johnson Space Center.

Eligibility and Educational Requirements

The agency’s posting lists four distinct educational pathways that satisfy the baseline criteria. Applicants may hold a master’s degree in a qualifying discipline such as engineering, biological science, physical science, computer science, or mathematics. Alternatively, two years of doctoral coursework in one of those fields is acceptable. A medical degree—including an MD, physician‑assistant credential, or nurse‑practitioner qualification—also meets the requirement, as does completion of a recognized test‑pilot school by July 2027.

Experience and Specialized Skills

Beyond education, candidates must demonstrate at least three years of professional experience after completing their degree or pilot training. The experience must align with one of several designated disciplines. Pilots, for example, must satisfy one of three flight‑hour thresholds: 750 hours as lead pilot of a high‑performance jet, 1,500 total fixed‑wing hours with at least 750 in command, or 1,000 rotary‑wing hours with 300 in command. Initial flight training and drone operation do not count toward these totals.

Applicants who focus on flight‑test roles must have either completed or be enrolled in a test‑pilot school, with graduation required by July 2027, plus three years of related flight‑test experience. Medical professionals need three years of post‑degree practice, with residencies counting toward that period. Candidates from biological and medical science, physical science, engineering, or operations backgrounds must also document three years of relevant work. Operations experience is defined as work in “high‑consequence environments that require real‑time decision‑making and intensive teamwork, where errors carry irreversible and physical risk to personnel, missions or vehicles.”

Physical, Medical and Security Standards

All aspirants will undergo a series of clearances, including comprehensive medical and psychiatric examinations, a background check, and a drug screening. Vision must be correctable to 20/20 in each eye. Physical fitness standards are rigorous: candidates must be capable of moderate to arduous activities such as heavy lifting, crouching, crawling, and exposure to inclement weather. A swimming test is also required.

Beyond physical ability, NASA emphasizes willingness to operate in dangerous, life‑threatening conditions and to live and work in remote, isolated, small or confined spaces for extended periods. Prospective astronauts must agree to deployments of twelve months or longer, accepting extreme isolation, austere living conditions, and separation from family.

NASA Administrator Jared Isaacman highlighted the strategic importance of the recruitment, noting that selected astronauts could “walk on the moon, live and work at the moon base, and help pioneer the systems and operations that will ultimately carry crews to Mars.” The agency’s recent crewed mission in April, which sent four astronauts around the moon and set a record for the farthest distance humans have traveled from Earth, underscores the urgency of building a workforce capable of sustained lunar presence.
