Astronaut Selection Training Platform
Want To Become
An Astronaut?
AstroTrainer is built for people who want to prepare more seriously for astronaut selection. It helps you train skills that can matter across several filters in the process, while also making the path feel more understandable and less opaque.
Instead of relying on drills alone, you can work across cognitive performance, astronaut-relevant study topics, and interview-style practice, all inside one preparation system with clearer structure.

Selection Reality Check
Astronaut selection odds are brutally low.
Public NASA, ESA, CSA, and JAXA campaigns all tell the same story: selection rates are tiny, and the filters span far more than one test. AstroTrainer is built to help applicants prepare more seriously across the kinds of cognitive, technical, and interview demands that show up across those public pathways.
