what's astronauts job
Astronaut is the job title for someone that has been selected, completed the training, and been certified by NASA, ESA, CSA, or JAXA. Cosmonaut is the job title for someone that has been selected and completed the training and been certified by the Russian Space Agency. Note, just going into space does not mean someone acquires either title. The spaceflight participants that pay the Russians for a trip to space are not cosmonauts nor astronauts.
