Questions & Answers

Q: How long does the process of becoming an astronaut take?

Becoming an astronaut is a lifelong process that involves years of education, training, and waiting for mission assignments. The application process alone takes about a year and a half.

Q: What are the dangers of being an astronaut?

The most dangerous moments in the job are the rocket launch and re-entry, which involve being exposed to hundreds of tons of explosive propellant and the need to dissipate acquired energy. There are also health risks associated with radiation exposure and the effects of microgravity on the body.

Q: What do biology experiments in space involve?

Biology experiments in space include studying the body's reaction to weightlessness, conducting ultrasound scans on the brain, heart, and eyes, analyzing eye structure with a laser, exploring plant growth in space, and studying the effects of infections on organisms.

Q: How do language barriers affect operations aboard the space station?

Language barriers are overcome through language training before flight. Astronauts learn Russian as they launch in a Russian spacecraft and communicate in multiple languages. The ability to learn languages is an important skill for astronauts.
