  • 30 Years Ago: STS-65 Lifts Off
    Space shuttle Columbia heads skyward after clearing the fixed service structure tower at Launch Complex Pad 39A at NASA's Kennedy Space Center in Florida. Plant life appears in the foreground. Launch occurred at 12:43 pm Eastern Daylight Time (EDT) on July 8, 1994. Once in Earth orbit, STS-65's six NASA astronauts and a Japanese payload […]
