SpaceX Launches NASA Satellite To Search For Alien Worlds

A SpaceX Falcon 9 rocket transporting the TESS satellite lifts off at the Cape Canaveral Air Force Station in Florida on Wednesday. The satellite will scan nearly the entire sky for alien worlds.

TESS — short for Transiting Exoplanet Survey Satellite — will spend two years searching for planets near bright, nearby stars.
