Adapted from a press release of Mars Odyssey’s THEMIS team, March 5. 2015:
NASA’s next Mars space probe, a lander named InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport), is due to touch down on the Red Planet in September 2016. InSight carries two main instruments, a heat-flow probe and a seismometer, both being deployed using a robotic arm. The heat probe requires that the ground within reach of the arm be penetrable by the probe, which will hammer itself into the soil to a depth of three to five meters.
InSight was provisionally selected for funding through NASA’s Discovery Program for launch in 2016 and the spacecraft design is based on NASA’s successful Phoenix Mars lander mission. It will touch down in one place and stay there for its entire mission, projected to last two Earth years. Its landing place has been chosen carefully with help from a Mars-orbiting heat-sensitive camera on NASA’s Mars Odyssey orbiter.
