The InSight lander touched down on the Red Planet today (Nov. 26) just before 3 p.m. EST (2000 GMT) and beamed home its first image from the surface mere minutes later. […]
InSight aims to carry out the first-ever in-depth investigation of the Martian interior. The lander will do this using a burrowing heat probe and a suite of three seismometers, which will measure tiny “marsquakes.” Mission team members will also track the wobble of Mars’ rotation axis using InSight’s communications equipment.
These observations should allow mission scientists to map the Red Planet’s interior structure in 3D — information that should, in turn, shed light on the formation and evolution of rocky planets in general, NASA officials have said. […]
InSight’s $850 million mission is scheduled to run for nearly two Earth years. It may take about that long for the lander to gather enough data to complete its mission goals, team members have said. […]
