Astronaut

The ultimate aerospace career

Overview

Becoming an astronaut is the most competitive career in aerospace — NASA selects roughly 10-12 candidates from 12,000-18,000 applicants every four years. But the path is not a mystery. It requires elite STEM academics, operational experience (military test pilot or deep scientific expertise), peak physical fitness, and the ability to perform under extreme pressure. The astronauts who will fly to the Moon and Mars in the 2030s and 2040s will work more closely with AI than any previous crew — onboard AI will manage spacecraft health, plan EVAs, monitor crew medical status, and serve as mission advisors when communication delays make real-time ground support impossible.

Career Progression

STEM Foundation & Leadership

Excel in advanced math, physics, and computer science. Build leadership through CAP, JROTC, or competitive teams. Start flight training if possible.

Bachelor's & Master's in STEM

Earn a bachelor's in engineering, science, or math, followed by a master's (minimum NASA requirement). Top candidates often hold PhDs or MD degrees.

Operational Experience

Build 1,000+ hours of pilot-in-command time (military track) or lead significant research programs (civilian scientist track). Military test pilot school is the strongest single credential.

NASA Application & Selection

Apply during open announcements (every 4+ years). Survive multi-round screening: application review, interviews, medical evaluation, and team assessments.

Astronaut Candidate (ASCAN) Training

Complete 2 years of training at Johnson Space Center: T-38 jet training, spacewalk training in the NBL, robotics, Russian language, survival skills, and AI systems familiarization.

Mission Assignment & Flight

Receive a crew assignment for ISS, Artemis lunar missions, or commercial station operations. Typical wait: 2-5 years after completing ASCAN training.
