Hi space nerds,

I'm not entirely sure if this post violates the rules of this sub so mods feel free to delete.

I'm interested in one day becoming an astronaut, and while I complete a degree in Mechanical/Aerospace engineering, I'm thinking about joining the Australian Defence Force reserve to gain some skills that might help me in selection. Unfortunately, I'm one inch too short to be a pilot astronaut, my only option is to be a mission specialist. Thus, I assume gaining pilot qualifications is not a priority (am I right in this assumption?) . Aside from general fitness (provided by almost all areas of army reserves), what other skills would be useful? I assume language training would be great, but I know that NASA also has to train astronauts with the ISS system. Would an Electronic Systems Technician position ("Maintain and repair high-tech Army assets in this part-time role; including vehicles, weapon systems, radios, medical equipment and electronic surveillance devices.") be useful. All the positions I am looking for non-degree based, as I would be studying as I am a reserve.

If anyone is interested here are the jobs:
