NASA engineers checking InSight's weather sensors

Called the Auxiliary Payload Sensor Suite (APSS), the sensors collect data on wind speed and direction, air temperature and pressure, and magnetic fields. Throughout each Martian day, or sol, InSight's main computer retrieves data stored in APSS' control computer for later transmission to orbiting spacecraft, which relay the data to Earth.

APSS is in safe mode and unlikely to be reset before the end of the month while mission team members work toward a diagnosis. JPL engineers are optimistic that resetting the control computer may address the issue but need to investigate the situation further before returning the sensors to normal.
