TESS Transiting Exoplanet Survey Satelite

NASA’s Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission that will discover thousands of exoplanets around nearby bright stars.

TESS is the next step in the seek planets outside of our solar system, including those that could support life. The mission will find exoplanets that periodically block part of the light from their host stars, events called transits. TESS will survey 200,000 of the brightest stars near the sun to search for transiting exoplanets.

The stars TESS will study are 30 to 100 times brighter than those the Kepler mission and K2 follow-up surveyed, which will enable far easier follow-up observations with both ground-based and space-based telescopes. TESS will also cover a sky area 400 times larger than that monitored by Kepler.

In addition to its search for exoplanets, TESS will allow scientists from the wider community to request targets for astrophysics research on approximately 20,000 additional objects during the mission through its Guest Investigator program.
