The Transiting Exoplanet Survey Satellite (TESS) is an all-sky transit survey, whose principal goal is to detect Earth-sized planets orbiting bright stars that are amenable to follow-up observations to determine planet masses and atmospheric compositions. TESS will conduct high-precision photometry of more than 200,000 stars during a two-year mission with a cadence of approximately 2 minutes. These targets will be read-out as postage stamps and be made available to the community as target pixel files (TPFs) and calibrated light curves. In addition, the full image frame will be read out approximately every 30 minutes. These Full Frame Images (FFIs) will enable users to conduct photometry on any target within the 24x96 degree field-of-view.
