NASA's Transiting Exoplanet Survey Satellite (TESS) is compact but mighty, with a body just 5 feet (1.5 meters) wide. This planet hunter may end up discovering more alien worlds than NASA's famous Kepler space telescope.

The spacecraft’s ultra-sensitive CCD cameras will collect the photons of 200,000 nearby stars, while searching for exoplanets. TESS will see much more of the sky than did Kepler, which focused on a single patch of sky during its four-year primary mission.

The TESS science team hopes to see images like this one when the satellite sends its first batch of data back to Earth, explained mission principal investigator George Ricker, of the Massachusetts Institute of Technology (MIT) explained. This image was taken with an engineering model of a TESS camera from a rooftop on the MIT campus.
