The Toughest Space Probe Ever – How NASA Dropped A Probe Into Jupiter
The Galileo mission to Jupiter featured a space probe which would be dropped into the atmosphere of Jupiter. Because of this planet’s gravity the atmosphere probe would experience conditions that no other spacecraft has seen. Entry velocities 7 times faster than those experiences by humans returning from orbit, massively higher temperatures and head fluxes, and no way to test the system fully on Earth.
