Who made the Parachute of NASA's Mars 2020 spacecraft? and how it helped for safe and smooth landing on red planet?
Credit:- NASA The Parachute traveled 742 million km with lander and rover. To slowdown the descent entry to the red planet. It was designed and tested at NASA's Jet propulsion laboratory southern California. The design of the Parachute is driven by loads. The forces the Parachute experiences as it is fully inflates. Loads are calculated by using atmospheric density, velocity, Parachute drag area & mass. The Parachute used for this mission was 40% larger than the Pathfinder . Design The material used to design must be strong & lightweight enough to fit inside a very small area. It was made with two durable lightweight fabrics Polyester and Nylon . It has a triple tethers that connects the Parachute to the bach shell. This tethers is made out of Kevlar the same material used in bullet proof vests. How it worked? First the Parachute is deployed at an altitude of about 10km above the martial surface. Next heat shield is released using 6 separation nut...
