Sturdy legs are needed to absorb the impact of the heaviest spacecraft to ever touch down on the Red Planet. NASA’s Perseverance rover continues to rack up tubes filled with rock core samples for the planned Mars Sample Return campaign. The joint effort by NASA and ESA (European Space Agency) see

This setup is being used at JPL to test a 16-inch-diameter footpad for a future Mars lander. The footpad was plunged into a testbed filled with 10,000 pounds of simulated Martian soil in order to see how deep it would sink. Credit: NASA/JPL-Caltech “You’d never be able to bend these steel rods with just your hands,” Montalvo said. “It’s pretty insane seeing just how much force goes into them, bending them nearly in half after a drop.”Testing of the lander’s full-size foot pads has been taking place in a box filled with 10,000 pounds of powdery, Mars-like soil. About 16 inches in diameter, the flat, round footpad attaches to an assembly with nearly a half-ton of iron weight plates.

Examining the effect of different geometric porosities on aerodynamic characteristics of supersonic parachutesThe safe landing of the probe is one of the most difficult challenges in Mars exploration, and the Mars supersonic parachute is extremely important for this process. To date, all the successful Mars exploration missions have used disk-gap-band (DGB) parachutes. However, the DGB parachute with the highest diameter of 21.35 m cannot be further used for future Mars exploration missions with higher loads.
