Status

TESS launched April 18 at 6:51 p.m. EDT from Cape Canaveral Air Force Station in Florida atop a SpaceX Falcon 9 rocket.

TESS will undergo a 60 day commissioning plan before collecting science data.

Once TESS begins its science mission, it will observe one sector at a time, starting in the southern hemisphere. TESS will continue to tile the sky with 27.4 day-long sectors during its 2 year prime mission.

Selections for Guest Investigator Cycle 1 were announced in January 2018. For GI Cycle 2, the spacecraft will survey the northern ecliptic hemisphere, and the proposal deadline is expected to be in Dec 2018.
