NASA said farewell on Wednesday to the InSight lander that spent four years probing the interior of Mars.
"But it has earned its richly deserved retirement."
InSight was one of four missions currently on the Red Planet – along with the US rovers Perseverance and Curiosity and China's Zhurong. It arrived on Mars in November 2018 to study the interior of the planet and its seismometer, made in France, paved the way for great advances. Seismic waves, varying based on the materials they pass through, offer a picture of the interior of the planet.
For example, scientists were able to confirm that the core of Mars is liquid and to determine the thickness of the Martian crust – less dense than previously thought and likely consisting of three layers.

NASA Mars lander InSight falls silent after 4 yearsIt could be the end of the red dusty line for NASA’s InSight lander, which has fallen silent after four years on Mars. The lander’s power levels have been dwindling for months because of all the dust coating its solar panels. Ground controllers at California's Jet Propulsion Laboratory knew the end was near, but NASA reported that InSight unexpectedly didn't respond to communications from Earth on Sunday.
