The Transiting Exoplanet Survey Satellite, better knows as TESS, is an MIT-led NASA mission to discover new planets like Earth. The satellite will picture the sky using four cameras on board, and at the end of its two-year mission will have surveyed 85 percent of the sky. TESS is expected to discover close to 50 planets for further study.
