Before you apply to NASA, you might want to take some time to peruse the original Lunar Rover Operations Handbook. Even though it dates back to April 19, 1971, a working knowledge of Apollo equipment couldn't hurt your chances.
Contrary to popular belief, the astronauts weren't just cocky top guns, they were also extremely tech savvy, which is an important skillset to have when tech support is roughly 238,000 miles away. Not only did they have to know how to operate the vehicles they relied on, they also needed to know how to fix them. So if you find this 221 page technical manual that covers everything from using the seat belts to operating the camera a little daunting, you might want to think twice about what you're getting yourself into if you're thinking of applying for a new job.
