Curiosity's Entry Descent & Landing on Mars
summary
Curiosity is a 2,000 lb rover that lands from ~13,000 mph using a heat shield, a 70 m supersonic parachute that sees ~65,000 lb loads, then an eight‑engine descent stage and the sky crane tether drop 20 m above ground; the whole sequence is the 7 Minutes of Terror. Engineers use CFD on supercomputers, helicopter drop tests, 3,000 fps imaging and photogrammetry, and Monte Carlo sims to size hardware and landing ellipse; it lands in Gale Crater (Aug 2012), works, drives ~10 km, finds past water and organics.
