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.
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
