The Transiting Exoplanet Survey Satellite (TESS) is a low cost, SMEX-class planet finder. In a two year all-sky survey, TESS will observe more than two million bright, nearby stars, searching for temporary drops in brightness that are caused by planetary transits. Such transits not only provide the means of identifying the planet, but also provide knowledge of the planet's diameter, mass density, surface gravity, temperature, and other key properties. TESS is expected to detect more than 1000 transiting exoplanet candidates. These detections will include a sample of 100 Super Earths -- small rock-and-ice planets with masses in the range 1 to 10 Earth masses -- orbiting nearby stars with spectral types spanning a broad range, including F, G, K, and M dwarfs. No ground-based survey can achieve this feat. TESS's "wide-shallow" survey complements the "narrow-deep" Corot and Kepler mission surveys. The resulting TESS Transit Catalog of the nearest and brightest stars in the sky will constitute a unique scientific legacy for followup observations. TESS will identify Super Earths orbiting IR-bright stars, ideal for JWST searches for planetary water and carbon dioxide.
The TESS mission is a collaborative effort led by researchers at the Massachusetts Institute of Technology, the Harvard-Smithsonian Center for Astrophysics, and the NASA Ames Research Center. Additional TESS partners include ATK Space Systems, the Las Cumbres Observatory Global Telescope Network, Lowell Observatory, the NASA Goddard Space Flight Center, the Infrared Processing and Analysis Center at the California Institute of Technology, the University of California (Berkeley and Santa Cruz), the SETI Institute, Espace Incorporated, the Geneva Observatory (Switzerland), the Tokyo Institute of Technology (Japan), and Institut Supérieur de l'Aéronautique et de l'Espace (France).
TESS is currently completing a NASA-funded Phase A study, and is proposed for launch in December 2012.
