Mars InSight Landed

Mars InSight landed on Mars with the purpose to help scientists understand the formation and early evolution of all rocky planets. Upon the auxiliary payload sensor subsystem sits the Temperature and Wind for InSight instrument(TWINS). InSight’s atmospheric pressure sensor sits inside the lander, with access to the atmosphere via an inlet on the lander deck. TAVISCorporation, Mariposa, California, built it. The device has more than 10-fold greater sensitivity to pressure variations at seismic frequencies than similar pressure sensors on NASA’s Viking and Mars Pathfinder landers
