Have you ever dreamed of floating in zero gravity, orbiting Earth, or even walking on the Moon or Mars? Becoming an astronaut may sound like science fiction, but it’s a real career — and one that’s more attainable than you might think. In this interactive guide, we’ll break down exactly how to become an astronaut, step-by-step.
> Did You Know?
Astronauts are trained not just to fly in space but to conduct science experiments, fix high-tech equipment, and survive in extreme conditions.
There are different types of astronauts:
NASA Astronaut Roles
ESA Astronaut Responsibilities
Minimum Requirement: A bachelor’s degree in a STEM field.

NASA and other agencies look for 3+ years of professional experience or 1,000+ hours of pilot-in-command time in jet aircraft (for pilots).
Work for organizations like:
Astronauts must pass rigorous physical exams. Here’s what agencies look for:
Vision: 20/20 (correctable OK)
Height: Usually 5'2" – 6'3" (varies)
Blood pressure: Within normal range
General health: Excellent stamina and mental fitness
> Fun Fact: Astronaut candidates even train in underwater environments and in giant centrifuges to simulate space conditions!
