Astronaut as a career: 12,000 applicants compete for 10 NASA seats in 2026
NASA’s 2025 astronaut class accepted just 0.08% of applicants—10 people from over 12,000 submissions. Private companies like Axiom Space and SpaceX hired more, but astronaut slots remain scarcer than Ivy League admissions. If you’re considering astronaut as a career, here’s exactly how selections work, what you’ll earn, and where to position yourself for 2026-2030 missions.
How much astronauts earn in 2026
NASA astronaut salaries follow the federal General Schedule (GS) pay scale. Base pay starts around GS-12 ($105,000) and caps at GS-15 ($195,200) for senior astronauts. The 2025 class averages $150,000 according to Fortune, but you won’t see billionaire paychecks like William Shatner’s Blue Origin flight.
2026 Astronaut salary comparison
| Employer | Base Salary Range | Bonuses/Perks |
|---|---|---|
| NASA (Govt) | $105,000 - $195,200 | Federal benefits, no equity |
