Mission Concept
Once launched, the telescope would conduct a two-year all-sky survey program for exploring transiting exoplanets around nearby and bright stars. TESS would be equipped with four wide-angle telescopes and charge-coupled device (CCD) detectors, with a total size of 192 megapixels. Science data will be processed and stored for three months onboard, and only data of interest will be transmitted to Earth for further analysis. Data collected by the spacecraft are also stored for three months, enabling astrophysicists to search the data for an unexpected, transient phenomenon, such as a gamma-ray burst.

Famous quotes containing the words mission and/or concept:
“The mission of men there seems to be, like so many busy demons, to drive the forest all out of the country, from every solitary beaver swamp and mountain-side, as soon as possible.”
—Henry David Thoreau (1817–1862)
“Teaching Black Studies, I find that students are quick to label a black person who has grown up in a predominantly white setting and attended similar schools as “not black enough.” ...Our concept of black experience has been too narrow and constricting.”
—bell hooks (b. c. 1955)
