Why do spacecraft wait so long to deploy their parachutes?
NASA and SpaceX work super hard to have heat shielding on the body of their spacecraft. I get that they go so fast that it can melt the steel. But they have a parachute on board, why don’t they deploy the parachute right away after starting to fall to earth? If they used Kevlar or something heat resistant, couldn’t that basically get rid of heat shielding because of how much slower they would go through the atmosphere?
