SpaceX Launches TESS: NASA's New Planet Hunter
A NEW ERA IN THE SEARCH FOR EXOPLANETS — and the alien life they might host—has begun. Aboard a SpaceX rocket, the Transiting Exoplanet Survey Satellite (TESS) launched on April 18, 2018, at 6:51 p.m. EDT. The TESS mission, developed with support from The Kavli Foundation, is led by the Massachusetts Institute of Technology (MIT) and the MIT Kavli Institute for Astrophysics and Space Research. Over the next two years, TESS will scan the 200,000 or so nearest and brightest stars to Earth for telltale dimming caused when exoplanets cross their stars' faces. Among the thousands of new worlds TESS is expected to discover should be hundreds ranging in size from about one to two times Earth. These small, mostly rocky planets will serve as prime targets for detailed follow-up observations by other telescopes in space and on the ground.
