Forty years ago today — July 28, 1973 — the second manned mission to the Skylab station was launched from the Kennedy Space Center on a Saturn 1B rocket.

The Skylab 3 crew — Alan L. Bean, Owen K. Garriott, and Jack R. Lousma — spent 59 days aboard the station. They installed a solar shield and did other station maintenance, and performed many solar and Earth observation experiments.
Skylab 3 is sometimes referred to as Skylab II, due to miscommunication about the mission numbering. The first Skylab mission, Skylab 1, was actually the mission that placed the station itself in orbit.
Ten years later, on this date in 1983, the Telstar 3A communications satellite was launched on a Delta rocket from Cape Canaveral. This was the first operational Telstar owned by AT&T; previously, AT&T had leased satellites.by
