After barreling through the Martian atmosphere at 5.5 km·s^-1 and withstanding temperatures of 1500℃, the capsule containing the lander deployed its parachute. At a distance of 9.2 km from the surface, it released its heat shield, exposing the lander’s legs. A couple of minutes later, the capsule dropped the lander into a free fall. With the aid of pulsed retrorockets, InSight settled onto Elysium Planitia, a flat, moderately barren patch of land 4.5°north of the Martian equator. Over the next few weeks, the spacecraft surveyed its new surroundings, checked its systems, took a selfie (Fig. 1), and got to work.展开更多
