Basically you'll be making sure organisms from Earth don't find their way to other planets during human and robot exploration. But still! Space!! Just look at the fascinating duties you'd have:
Planetary protection is concerned with the avoidance of organic-constituent and biological contamination in human and robotic space exploration. NASA maintains policies for planetary protection applicable to all space flight missions that may intentionally or unintentionally carry Earth organisms and organic constituents to the planets or other solar system bodies, and any mission employing spacecraft, which are intended to return to Earth and its biosphere with samples from extraterrestrial targets of exploration.
And anyways, the position pays beaucoup bucks: anywhere from $124,406 to $187,000 per year. The position is limited, lasting only three years, but if you're really good at evaluating robot and human compliance with ~international space code~ there's a chance for a two-year extension.
I mean, there's just the little hiccup that you might technically have to be well-versed in planetary protection as defined by international guidelines, and you need a degree in physical science, engineering, or mathematics, with extensive knowledge in mechanics, dynamics, properties of materials, and electronics, yadda yadda yadda.
