SA-206 lifts off from Kennedy Space Center's launch complex 39B, in Florida, on May 25, 1973, for the first manned Skylab mission (SL-2) with astronauts Pete Conrad, Joseph Kerwin, and Paul Weitz. The Saturn IB, developed under the direction of the Marshall Space Flight Center (MSFC), launched five manned Earth-orbital missions between 1968 and 1975: Apollo 7, Skylab 2, Skylab 3, Skylab 4, and the Apollo-Soyuz Test Project (ASTP).

S66-54455 (13 Sept. 1966) --- Astronaut Richard F. Gordon Jr., Gemini-11 pilot, attaches a tether line from his spacecraft to the Agena Target Docking Vehicle (ATDV) during a spacewalk. This view was taken over the Atlantic Ocean at approximately 160 miles above Earth on Sept. 13, 1966. With the aid of the ATDV, Gordon and astronaut Charles (Pete) Conrad Jr., command pilot, set a new altitude record of 750 miles during the GT-11 mission. Photo credit: NASA

This Skylab-2 onboard photograph shows astronaut Charles "Pete" Conrad exercising on a stationary bicycle (ergometer) used for monitoring the metabolism of the astronauts. The ergometer was used to conduct both Vectorcardiogram experiment (M093) and Metabolic Activity experiment (M171). Experiment M093 was a medical evaluation designed to monitor changes in astronauts' cardiovascular systems, while Experiment M171 was to measure astronauts' metabolic changes during long-duration space missions.

This is an image of the Saturn IB vehicle that lifted off on May 25, 1973, carrying the crew of the Skylab-2 (SL-2) mission. The Saturn IV launch vehicle was used to carry a crew of three astronauts to the Skylab. The SL-2 mission launched the first crew to the Skylab; astronauts Charles "Pete" Conrad, Joseph Kerwin and Paul Weitz. This crew made urgent repair work on the damaged Skylab to make it operational and habitable. The goals of the Skylab were to enrich our scientific knowledge of the Earth, the Sun, the stars, and cosmic space; to study the effects of weightlessness on living organisms, including man; to study the effects of the processing and manufacturing of materials utilizing the absence of gravity; and to conduct Earth resource observations. The duration of this mission was 28 days.
