NASA Tests Prototype Europa Lander
engineers at NASA’s Jet Propulsion Laboratory in Southern California tested the landing system for a proposed future mission that would touch down on Jupiter’s icy moon Europa.
()
This system for the proposed Europa Lander is an evolution of hardware used on previous NASA lander missions. It includes the architecture used for the “sky crane maneuver” that helped lower NASA’s Curiosity and Perseverance rovers onto the Martian surface, which would give the lander the stability it needs during touchdown. Although this landing architecture was developed with Europa as the target, it could be adapted for use at other moons and celestial bodies with challenging terrain.Four bridles, suspended from an overhead simulated propulsive descent stage, maintain a level lander body. The four legs conform passively to the terrain they encounter as the lander body continues to descend toward the surface. Each leg consists of a four-bar linkage mechanism that controls the leg’s pose before and during landing. The legs are preloaded downward with a constant force spring to help them rearrange and compress the surface they encounter prior to landing, giving them extra traction and stability during and after the landing event.
Acting like a skid plate, the belly pan provides the underside of the spacecraft with protection from potentially harmful terrain. The belly pan also resists shear motion on the terrain it interacts with. Once the belly pan contacts the surface, sensors trigger a mechanism that quickly locks the legs’ “hip” and “knee” rotary joints, resulting in a table-like stance. At this point, the job of ensuring lander stability shifts from the bridles to the legs. This shift keeps the lander level after the bridles are unloaded.
Although the lander locks the legs in place once stability is achieved, it would be cool if it could walk around to find a better spot - like the Hyperion robot walking chair created in the Chiba Institute of Technology in Japan.
