Mission objectives
The Transiting Exoplanet Survey Satellite (TESS) is a NASA-sponsored Astrophysics Explorer-class mission that is performing a near all-sky survey to search for planets transiting nearby stars. The primary goal of TESS is to discover planets smaller than Neptune that transit stars bright enough to enable follow-up spectroscopic observations that can provide planet masses and atmospheric compositions.

Overview
TESS launched on April 18, 2018 and after a series of maneuvers was placed in a highly-elliptical 13.7 day orbit around the Earth. TESS began regular science operations on July 25, 2018. In the 2-year prime mission, TESS monitors over 200,000 main-sequence dwarf stars with four wide-field optical CCD cameras to detect periodic drops in brightness caused by planetary transits. TESS obtains full-frame images (FFIs) of the entire, four camera field-of-view (24 x 96 degrees) at a cadence of 30 minutes to facilitate additional science.

TESS data processing pipeline
The TESS data processing pipeline is currently being developed by the Science Processing Operations Center (SPOC) at NASA Ames Research Center and builds on the legacy of the Kepler data processing pipeline. Further information regarding this product is available from https://heasarc.gsfc.nasa.gov/docs/tess/documentation.html

Contents
The data in this torrent is produced by the SPOC at NASA Ames Research Center and contains calibrated full-frame images (FFIs) for an observing sector that spans roughly 27 days.  Details about this particular sector can be obtained from https://tess.mit.edu/observations/sector-20

The permanent home for this dataset is through the official archive for TESS mission data products at the Mikulski Archive for Space Telescopes (MAST) which is hosted at the Space Telescope Science Institute (STScI) at the following url https://archive.stsci.edu/tess/

Providing TESS data through torrent is currently being done on a trial basis through the TESS  Science Office (TSO) at MIT in order to determine the community interest in this alternative.  It is subject to cancellation at any time. The current plan is to seed the two most recent TESS observing sectors.  Observing sectors older than the two most recent will no longer be seeded by the TSO. Each observing sector is broken down into 16 separate torrents; one torrent for each camera and ccd combination. If you are interested in data for just a few targets, then we encourage you to use the following tools to identify which camera and ccd your targets appear on

This will save one from having to download all the data for a sector.
