TESS Spacecraft Starts Science Operations

News article posted on by Tom Barclay

NASA’s Transiting Exoplanet Survey Satellite has started its search for planets around nearby stars, officially beginning science operations on July 25, 2018. TESS is expected to transmit its first series of science data back to Earth in August, and thereafter periodically every 13.5 days, once per orbit, as the spacecraft makes it closest approach to Earth. The TESS Science Team will begin searching the data for new planets immediately after the first series arrives.

We have updated our TESS status page to list the dates when the 13 Southern hemisphere sectors will be observed.
