From Training to Launch: The Journey of NASA's Moon Mission Astronauts.

Becoming an astronaut is a difficult and dangerous job, but if you meet the minimum requirements, you can apply for NASA's Astronaut Candidate Program. The basic requirements include being a U.S. citizen, having a master's degree in a STEM field, and passing a physical exam. The pay isn't great, and the job is risky, but the perks include seeing the world from a unique perspective. If you don't meet the requirements or have the money to pay for a space trip, you could try working in a lunar brick factory to help establish a permanent base on the moon.
