TESS is designed to carry out the first spaceborne all-sky transiting exoplanet survey. [18][30] It is equipped with four wide-angle telescopes and associated charge-coupled device (CCD) detectors. Science data are transmitted to Earth every two weeks. Full-frame images with an effective exposure time of two hours are transmitted as well, enabling scientists to search for unexpected transient ...
TESS ’s primary mission was a two-year-long survey that imaged about 75% of the starry sky. On , TESS entered its extended mission which will be completed in September 2022.
TESS Observations TESS observes the sky in sectors measuring 24° x 96°. Each sector is observed for two orbits of the satellite around the Earth, or about 27 days on average. The field-of-view is oriented along a line of ecliptic longitude with the instrument boresight generally pointing at ±54° ecliptic latitude, which centers Camera 4 on an ecliptic pole. By orienting the fields in this ...

TESS has four identical, highly optimized, red-sensitive, wide-field cameras that together can monitor a 24 degree by 90 degree strip of the sky. By monitoring each strip for 27 days and nights at 2 second cadence (postage stamp data around selected targets will be binned to 20s and 120s cadence before download, while the full frame images (FFIs) will be downloaded at 200s cadence), TESS will ...
TESS, the Transiting Exoplanet Survey Satellite is an MIT-led NASA mission discovering transiting exoplanets via an all-sky survey. The TESS Science Office is run by MIT and the Center for Astrophysics | Harvard & Smithsonian.
