InSight mission ended

detected by InSight
NASA today announced that it has officially ended the mission of the InSight lander on Mars.
Mission controllers at the agency’s Jet Propulsion Laboratory (JPL) in Southern California were unable to contact the lander after two consecutive attempts, leading them to conclude the spacecraft’s solar-powered batteries have run out of energy – a state engineers refer to as “dead bus.”
NASA had previously decided to declare the mission over if the lander missed two communication attempts. The agency will continue to listen for a signal from the lander, just in case, but hearing from it at this point is considered unlikely. The last time InSight communicated with Earth was Dec. 15.
Other than the success of InSight’s seismometer, this project was mostly a failure. Its launch was delayed two years, from 2016 to 2018, because of problems with the original French seismometer, forcing JPL to take over. Then its German-made mole digger failed to drill into the Martian surface, causing the failure of the lander’s second instrument, a heat sensor designed to measure the interior temperature of Mars.
Fortunately the seismometer worked, or otherwise it would have been a total loss. That data has told us much about Mars and its interior.
