NASA's TESS and its discoveries
  • A SpaceX Falcon 9 rocket carrying a TESS spacecraft lifts off on Wednesday, April 18, 2018, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

    TESS, which stands for Transiting Exoplanet Survey Satellite, is a telescope/camera that will hunt for undiscovered worlds around nearby stars, providing targets where future studies will assess their capacity to harbor life, NASA says.

Scheduled for an April 2018 launch, the spacecraft will prowl for planets around the closest, brightest stars. These newfound worlds eventually will become prime targets for future telescopes looking to tease out any signs of life.
