It 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 dust coating its solar panels. Ground controllers at California’s Jet Propulsion Laboratory knew the end was near, but Nasa reported that InSight unexpectedly did not respond to communications from Earth on Sunday.
