Landing on Mars on November 26, NASA’s InSight lander has used its robotic arm outfitted with grippers to emplace its Seismic Experiment for Interior Structure, or SEIS, on the Red Planet’s surface.

On Wednesday, Dec. 19, the seismometer was gently placed onto the ground directly in front of the lander, about as far away as the arm can reach – 5.367 feet, or 1.636 meters, away).

On the level

In the coming days, the InSight team will work on leveling the French-built seismometer, which is sitting on ground that is tilted 2 to 3 degrees. The first seismometer science data should begin to flow back to Earth after the seismometer is in the right position.

According to a JPL press statement, engineers and scientists at JPL, the French national space agency Centre National d’Études Spatiales (CNES) and other institutions affiliated with the SEIS team, will need several additional weeks to make sure the returned data are as clear as possible.

Next steps

In early January, engineers expect to command the robotic arm to place the Wind and Thermal Shield over the seismometer to stabilize the environment around the sensors.

By Late January, assuming that no problems crop up, the InSight team plans to deploy the German-provided Heat Flow and Physical Properties Probe, or HP3) onto the Martian surface. HP3 will be on the east side of the lander’s work space, roughly the same distance away from the lander as the seismometer.
