NASA's "Tess" is Searching for Alien Worlds
on 16 April 2018
NASA's Tess (Transiting Exoplanet Survey Satellite) is going in search of some 200,000 of the brightest stars, in an attempt to find alien worlds. The satellite will hitch a ride with SpaceX's Falcon 9 and then spend two years floating around space, not just to observe but ultimately to find exoplanets (potentially habitable planets). Tess will be "flung into a highly elliptical orbit around Earth that has never been attempted before" and each orbit will take 14 days to complete, as she scours for alien planets and then sends data back to earth.
