InSight landed successfully on Mars on 26 November 2018 and had some time to settle, i.e. extending its robotic arm. An Instrument Deployment Camera (IDC), located on its elbow, is going to take photos of the terrain in front of the lander. These images will help mission team members determine where to set InSight's seismometer and heat flow probe — the only instruments ever to be robotically placed on the surface of another planet. A full mosaic of what InSight surroundings look like is expected by early next week.
Another camera, called the Instrument Context Camera, is located under the lander's deck. It will also offer views of the workspace, though the view won't be as pretty as dust accumulated on its lens.
Placement of the instruments is critical, and the team is therefore proceeding with caution. It could take up to two to three months before the instruments have been situated and calibrated.
Two of InSight’s sensors, an air pressure sensor inside the lander and the seismometer sitting on the lander's deck, captured the sound of wind on 1 December 2018, from northwest to southeast.
This is the only phase of the mission during which the seismometer, called the Seismic Experiment for Interior Structure (SEIS), will be capable of detecting vibrations generated directly by the lander. Soon, it will be placed on the Martian surface by InSight's robotic arm in order to detect the lander's movement, allowing it to detect marsquakes. SEIS will detect vibrations caused by them, that can tell us more about the Red Planet’s interior.
