Launched atop a SpaceX Falcon 9 rocket on April 18, 2018, TESS is a planet-hunting spacecraft designed to search for Earth-like planets. TESS will observe 400,000 stars across the whole sky to catch a glimpse of a planet transiting across the face of its star. TESS will also enable astronomers to measure the masses, atmospheric compositions, and other properties of many smaller exoplanets for the first time.
