The Skylab space station was launched May 14, 1973, from the NASA Kennedy Space Center by a huge Saturn V launch vehicle, the moon rocket of the Apollo Space Program.
Skylab's achievements are a summary of the accomplishments of many ground-based persons as well as its three separate crews who were launched in Apollo-type command modules by Saturn IB vehicles on May 25, July 28, and November 16, 1973.
The capability to conduct longer manned missions was conclusively demonstrated in Skylab, first by the crew returning from the 28 day mission and, more forcefully, by the good health and physical condition of the second and third Skylab crews who stayed in weightless space for 59 and 84 days respectively.

 Skylab from Above - Picture - MSN Encarta
Skylab 4 astronauts took this photograph of the United States Skylab space station over the cloud-covered earth from their Apollo spacecraft as they prepared to return home on February 8, 1974.
The sheet of gold-colored material stretched over the station is a makeshift sun shield that the astronauts of Skylab 2 set up to replace a sun and micrometeoroid shield that fell off during launch.
As the shield fell, it knocked loose a winglike array of electricity-producing solar panels that was supposed to be in the same position on the left as the remaining array is on the right.

 Skylab
Skylab consisted of the orbital workshop itself, an airlock module, a multiple docking adapter, and the Apollo telescope mount.
Skylab was equipped to observe Earth’s natural resources and the environment, and activity on the Sun.
Before the Skylab 4 crew left, they boosted the space station to a slightly higher orbit which varied from 430 to 455 km.

 eoPortal directory: Skylab Space Station
The overall objectives of Skylab were to learn about space and to have people live and work in space for longer periods in a laboratory-like environment to conduct experiments (a limiting factor on time in orbit was how much supplies the crew could bring with them).
Skylab was unique in that the presence of man made it possible to use photographic film as the prime detection and recording media for a variety of optical instruments and experiments.
A main goal of Skylab was the study of the sun, in particular the corona with its flares and coronal transients, referred to as CMEs (Coronal Mass Ejections), in several wavelength regions not accessible from Earth.

 Skylab Summary
Skylab was actually the refitted S-IVB second stage of a Saturn IB booster (from the AS-212 vehicle), a leftover from the Apollo program originally intended for one of the canceled Apollo earth orbital missions.
Skylab was launched May 14, 1973 by a Saturn INT-21 (a two-stage version of the Saturn V launch vehicle).
Increased solar activity, heating the outer layers of the earth's atmosphere and thereby increasing drag on Skylab, led to an early reentry at approximately 16:37 UTC July 11, 1979.

 Skylab
Therefore, for Skylab to use the lithium hydroxide filters, a large supply had to be carried on board Skylab or delivered with each crew, which, since keeping weight to a minimum is always a desired effect for spacecraft, was not possible.
Skylab itself had a Sun seeker mounted in the ATM that was designed to remain pointing towards the center of the Sun, giving the Skylab module a reference vector to the Sun.
Though Skylab did have thrusters, not enough fuel could be carried on board to cover all the manuveurs that were to be required during the three Skylab missions.

Skylab 4, launched on November 16, 1973, was the last of the Skylab missions.
Skylab 1 was supposed to orbit the earth until the 1990's, but due to the effect of the solar wind gradually shifted the craft's orbit closer to the earth's atmosphere, and Skylab 1 fell to the earth over a wide area from the Indian Ocean to southwestern Australia.

 Mass Measurements aboard Space Station Skylab
The orbit of Skylab was not high enough to avoid atmospheric friction, and over the years the station gradually lost altitude.
Prior to the Skylab mission it was observed that both US and Russian astronauts returning from space had lost weight, and NASA worried whether this implied some physical deterioration which could grow worse on longer flights.
To better observe the process, Skylab carried three mass-measuring devices--two small ones (experiment M074) for measuring the intake and outgo of each astronaut, and a large one (experiment M172) with an oscillating chair, designed for daily monitoring of the weight of the astronauts.

NASA had them go ahead and dock-figuring that they were safer aboard Skylab-and then, 6 days later, noted a problem with another thruster quad.
Activities were curtailed for a couple of days, and the docs back in Houston had them change their diet; after about 5 days, they were adjusted well enough to zero-G that NASA had them go on with the flight plan.

 The Rescue That Never Was: Skylab 3
Long before Skylab was ever built, planners began to realize that unlike past programs, a rescue could occur if there were problems with the CSM while it was docked to the station.
Because of Skylab’s large stores of oxygen, food, and water a crew could stay onboard for several weeks until a rescue effort could be prepared and eventually launched.
Quickly, an Apollo spacecraft (CSM 118) reserved for the Skylab 4 mission began to be fitted with a “rescue kit.” If all went well, the rescue CSM would be ready for launch in about 3 weeks.
