NASA’s TESS Returns to Science Operations

NASA’s TESS (Transiting Exoplanet Survey Satellite) has returned to work after science observations were suspended on April 8, when the spacecraft entered into safe mode. All instruments are powered on and, following the successful download of previously collected science data stored in the mission’s recorder, are now making new science observations.

Analysis of what triggered the satellite to enter safe mode is ongoing.

The TESS mission is a NASA Astrophysics Explorer operated by MIT in Cambridge, Massachusetts. Launched in 2018, TESS has been scanning almost the entire sky looking for planets beyond our solar system, known as exoplanets. The TESS mission has also uncovered other cosmic phenomena, including star-shredding black holes and stellar oscillations. Read more about TESS discoveries at nasa.gov/tess.

NASA’s TESS Temporarily Pauses Science Observations

NASA’s TESS (Transiting Exoplanet Survey Satellite) entered into safe mode April 8, temporarily interrupting science observations. The team is investigating the root cause of the safe mode, which occurred during scheduled engineering activities. The satellite itself remains in good health.

The team will continue investigating the issue and is in the process of returning TESS to science observations in the coming days.
