Since you were little, you have probably associated space careers with astronauts, walking on the moon, Neil Armstrong, and space shuttles. Those certainly make a lasting impression, but you should probably know two things, if nothing else: first, not every space career involves hopping around in a big spacesuit, and second, there are lots of opportunities available for exciting space careers today.

It might change your life.
