Freedom 7 was a US spacecraft (capsule) of Mercury-Redstone 3 manned space mission, which put the first American in space in a suborbital flight, Alan Shepard, on May 5, 1961. Freedom 7 was launched on a Redstone rocket, which took off from Cape Canaveral, Florida. The capsule's frame was made of titanium and covered with steel and beryllium shingles. The base of the spacecraft was a beryllium heat sink, a technique for preventing the heat generated during reentry from harming an astronaut. The spacecraft consisted of a conical pressure section topped by a cylindrical recovery system section. Within Freedom 7, the astronaut breathed pure oxygen at 264mm of mercury.
