Despite its rough start and legendary cramped quarters, the Soyuz capsule is one of the most enduring pieces of Soviet technology the world still uses.

For all the chutzpah and arrogance of most space engineers, the world's space explorations still depend critically on a Soviet piece of technology from 1967: the Soyuz capsule.

It has outlived all of its competitors, and even played a surprising role in the middle of the Cold War. Check out the video to learn more details of this engineering feat.
