The Saturn IB was an uprated version of the Saturn I, which featured a much more powerful second stage, the S-IVB. Unlike the earlier Saturn I, the IB had enough throw weight to launch the Apollo Command/Service Module or Lunar Module into Earth orbit, which made it invaluable for testing the Apollo spacecraft while the larger Saturn V needed to send them to the moon was still being developed. The Saturn IB was later used for manned Skylab flights, and the Apollo-Soyuz Test Project. The final production run (such as Skylab launch vehicles) did not have the alternating black and white tanks on the first stage that were hallmarks of the earlier runs.
With the project reaching 30 years of age, the final Space Shuttle mission took to the skies in July 2011. Over the three decades, 135 missions took place, using five different space-worthy Orbiters; Columbia, Challenger, Discovery, Atlantis and Endeavour. Developed as a hybrid vehicle, the Space Transportation System consisted of the aircraft-like Orbiter that carried crew and cargo, and the Booster section, consisting of the giant External Tank (the ET), and two Solid-fuel Rocket Boosters (the SRBs). At launch, the Orbiter’s three engines fire, powered by fuel from the External Tank, plus the two SRBs, developing a thrust of over seven million pounds (three million kg). The SRBs are jettisoned at an altitude 28 miles (45km), and the ET at 70 miles (112.5km). Having completed its mission, the Orbiter returns unpowered, and lands on a runway like a conventional aircraft.

One of the most successful space designs ever, the initial flight of the Vostok which carried the first human being into space was launched on April 12, 1961, Vostok 1, carrying cosmonaut Yury A. Gagarin, made a single orbit of Earth before reentry. The Vostok series included six launchings over a two-year period (1961-63). The final two missions in June 1963 by Vostok 5, followed two days later by Vostok 6, carrying Valentina V. Tereshkova, the first woman in space, were notable in that the two spacecraft travelled at times only 3 miles (4.8 km) apart, setting the stage for future space dockings between orbiting vehicles.
In May 1973 Skylab was launched using a two-stage Saturn V, sometimes called a Saturn INT-21. It was the only launch not directly related to the Apollo lunar landing program. Three crews lived aboard Skylab from May 25, 1973 to February 8, 1974, with Skylab remaining in orbit until July 11, 1979.
