NASA’s Perseverance meanderer’s new wheels can hold and better withstand rocks
NASA’s new Mars meanderer, Perseverance, approaches culmination as it is fitted with new haggles gigantic compressed air brake parachute.
The meanderer had its wheels fitted just because a year ago, yet those were building model wheels which are utilized for fitting and testing, for example, checking whether the wanderer could remain on its own haggles its own weight. With that testing presently complete, the NASA group could expel the model haggles them with the genuine wheels that the meanderer will run on when it arrives at Mars.
Persistence has marginally unexpected wheels in comparison to NASA’s different Mars meanderer, Curiosity. Persistence’s wheels are somewhat bigger in measurement, at 52.6 centimeters (20.7 inches) versus 50.8 centimeters, and are likewise marginally smaller. Interest’s wheels have 24 generally divided tracks in a chevron design, which keeps the meanderer from slipping sideways as it moves across precarious surfaces like sand as it scales the twisting way of Mount Sharp.
Steadiness, then again, has wheels with 48 tenderly bent tracks that are dispersed intently together, which NASA engineers have discovered give a similar measure of grasp as the chevron design yet can all the more likely withstand pressure from sharp shakes. Interest has had issues with little breaks in a portion of its wheels, and in spite of the fact that the wheels should in any casework for the lifetime of the meanderer, the fresher plan ought to forestall this sort of mileage.
Notwithstanding the wheels, the wanderer has additionally had another fundamental segment coordinated: Its parachute, which will slow the meanderer’s plummet onto Mars and assist it with contacting down onto the planet’s surface tenderly without harming any of the sensitive parts. The Perseverance wanderer will be the heaviest payload at any point conveyed on Mars, so the parachute covering made of nylon, Technora, and Kevlar fiber should be huge — 70.5 feet wide — to slow the full weight of 2260 pounds of the meanderer from Mach 1.7 to 200 mph.
Dispatch of the wanderer is planned for between July 17 and August 5 this year.
