The next-gen exoplanet-hunting satellite by NASA, Transiting Exoplanet Survey Satellite (TESS), is planned to launch on SpaceX Falcon 9 from Cape Canaveral FL Space Launch Complex 40 on April 16 at 18:32. TESS is the first NASA Astrophysics satellite mission to launch with SpaceX. The craft will perform 2 months of maneuvering and at least 5 burns to place it in a lunar flyby orbit to achieve a final highly-elliptical HEO with a period of 13.65 days in 2:1 resonance with the Moon. TESS will monitor 500,000 stars in a 2-year survey of the solar neighborhood, searching for temporary drops in brightness caused by planetary transits. Four wide-field charge couple device cameras each with 7 stacked lenses will help observe thousands of exoplanets and determine the mass, size, density and orbit. The spacecraft will have a launch mass of 350 kg. Its solar arrays will produce 390 watts of electricity, and it will communicate with Earth at 8 ground stations in USA once every 2 weeks at 100 mbps. Likely to run out of fuel within the next few months, the significant Kepler and K2 mission is now in campaign 17 and has discovered more than
