NASA has released retro recruitment posters showing a range of future job positions that will need to be filled once humans make their way to Mars.

Called ‘Mars Explorers Wanted’, the eight posters were originally created for an exhibit at the Kennedy Space Center Visitor’s Complex in 2009 and designed to give people an idea about what’s next in the future of space exploration and if they could play a role in the journey.

The full set is available online to the public.
