In the summer of 1975, 50 years ago, millions around the world watched an event that would have been unthinkable only a few years earlier. An American Apollo spacecraft docked with a Soviet Soyuz capsule leading to a handshake in Earth orbit. As the first international space mission, the Apollo Soyuz Test Project led to extensive cooperation ongoing today.
“Six, five, four, we’ve gone for main engine start and we have liftoff of America’s first Space Shuttle,” said NASA launch commentator Hugh Harris as more than a decade of development culminated with the dawn of a new era of spaceflight. John Young and Bob Crippen lifted off aboard Columbia on April 12, 1981. The Space Shuttle was an idea born in the closing days of the 1960s race to the Moon. The concept had many technological hurdles to overcome. After numerous delays, it became a triumph of American technology and engineering.
