Land a piece of space history

The first of the United States' manned flight programs, Project Mercury aimed successfully to place a spacecraft into earth orbit. Fabrication of the Mercury suits was started in 1959, and NASA selected the B.F. Goodrich Company for the task. The Mercury space suit was basically a modified version of the U.S. Navy's Mark IV high altitude pressure suit, with the most notable modification being an aluminized nylon outer layer to assist thermal control.

Alexei Isayev specialized in small-scale, liquid-fuelled rocket engines for Soviet manned and unmanned spacecraft. The present engine is for a S-75 Dvina, a high-altitude, command-guided, SAM. Since its first deployment in 1957 it has become the most widely-deployed air defense missile in history. The missile came to the world's attention when an S-75 battery, using the newer, longer-range and higher-altitude V-750VN missile shot down the U-2 spy plane of Francis Gary Powers as he was flying over the Soviet Union on May 1, 1960.
