Yes, you read that correctly. NASA is looking for someone to be the Guardians of the Galaxy for real, or at least the Guardian of Earth. Start dusting off those X-Files and ALF episodes and prepare for the job of a lifetime because NASA is looking to pay somebody six-figures to protect Earth from aliens as well as "organic-constituent and biological contamination."
The position is expected to last 3 years, but could be extended up to 5 years with a possible promotion and there is currently only one similar position like this in the world at this time and it's through the European Space Agency. If you are interested (and who isn't?), you can apply right here: USAJOBS.GOV and good luck. Make sure to use Han Solo or Captain Kirk as a reference for higher visibility, there's bound to be hundreds of thousands applicants and you should stand out.
