The Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA's Explorers program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission.[1] It was launched on April 18, 2018 atop a Falcon 9 rocket.[2][7][8][9] During its 2-year primary mission, it is expected to find more than 20,000 exoplanets,[10] compared to about 3,800 exoplanets known when it launched.[11] The first light image from TESS was taken on August 7, 2018, and released publicly on September 17, 2018.[6][7][8]
