WebThe "tail" of the capsule when it went into orbit would become its "nose" during reentry. Their original capsule configuration - a squat, domed body with a nearly [95] flat heatshield - resembled the Mark II missile warhead. ... including use of the heat sink on a blunt body as the best thermal protection procedure. The question remained open ... WebThe first Mercury spacecraft used a blunt body design and a heat sink, but later versions used the blunt body design and an ablative surface. General Electric built an ablative, semi-blunt (slightly rounded) reentry vehicle for the Air Force and CIA Discoverer/ Corona spacecraft , which returned film from spy satellites.
