MarsSampleReturn: How Do You Test the Legs of NASA's Heaviest Mars Spacecraft?

As part of a NASA-ESA campaign to return rock and soil samples from Mars to Earth, engineers at NASA's Jet Propulsion Laboratory are designing a lander which will be the heaviest spacecraft ever to touch down on the Red Planet. Engineers are dropping prototype lander legs and footpads to measure how they absorb the shock of hitting Martian ground. One test involves a model that is roughly one-third the size of the spacecraft's final design. Meanwhile, in a sandbox, a full-size foot pad is being dropped into simulated Martian soil.
