The 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.

Next-generation supersonic parachutes conducted by NASA, such as disksail parachutes, are alternatives to DGB parachutes. Disksail parachutes have larger porous gaps and smaller porous seams on the canopy surface than DGB parachutes. However, there are few studies on the aerodynamic characteristics of supersonic parachutes with different geometric porosity structures and locations.

Hence, the influence mechanism of porous seams or gaps and their locations on the performance of supersonic parachute systems in Martian atmospheric conditions remains unclear.

When the first astronauts land on Mars, they may have the descendants of a microwave-oven-size device to thank for the air they breathe and the rocket propellant that gets them home. That device, called MOXIE (Mars Oxygen In-Situ Resource Utilization Experiment), has generated oxygen for the 16th and final time aboard NASA's Perseverance rover.
