If you’ve ever wanted to go into space, this is your chance. NASA is looking for astronauts that will staff the Artemis missions, which have a goal of setting up a station on the moon and eventually sending astronauts to Mars. The application period for the new class, which will be the first in four years, opens on March 2nd and closes on March 31st.

NASA doesn’t have a set number of astronauts they’re looking for, but past classes have ranged in size from eight to 12 people. Applicants must be U.S. citizens and have two years of related professional experience, as well as a master’s degree in a STEM field.
