If you want to be a space explorer, you’re one step closer to quitting your day job. NASA is now accepting applications for its astronaut program. It's the first time the space agency has opened up applications since 2011. If you think you have what it takes to break free of the bonds of Earth's gravity and live in the cold, harsh vacuum that engulfs our tiny planet, then you can apply online at USAJobs.gov. Applications will be accepted through February 18th.
