Transiting Exoplanet Survey Satellite (TESS) Is In Safe Mode

NASA’s Transiting Exoplanet Survey Satellite (TESS) entered into safe mode on Monday, Oct. 10.

The spacecraft is in a stable configuration that suspends science observations. Preliminary investigation revealed that the TESS flight computer experienced a reset.

The TESS operations team reported that science data not yet sent to the ground appears to be safely stored on the satellite. Recovery procedures and investigations are underway to resume normal operations, which could take several days.

TESS launched in April 2018 and has since discovered more than 250 exoplanets – worlds beyond our solar system – and thousands of additional candidates. The agency will provide additional updates https://www.nasa.gov/feature/goddard/2022/tess-status-update
