'SKYLAB: THE SECOND MANNED MISSION, A SCIENTIFIC HARVEST

JSC 627 - (1974) - 36 1/2 Minutes

Astronauts: Alan L. Bean, Owen K. Garriott, and Jack R. Lousma

Launch date: July 28, 1973

Covers the Skylab launch activities and docking with unmanned SL-1 workshop. Includes observations of student experiments (the Minchmog minnows and Arabella, the spider), crew medical experiments, exercise routines, and the enabling of the Earth Resources Experiments Package. Shows planet Earth documentation, manned operation of the Apollo Telescope Mount for observations of the Sun and beyond, outside EVA activity, testing of the Astronaut Maneuvering Unit, experiments to explore industrial uses of space, and the Skylab living routine.'

Originally a public domain film from NASA, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Skylab 3 (also SL-3 and SLM-2) was the second crewed mission to the first American space station, Skylab. The mission began July 28, 1973, with the launch of three astronauts in the Apollo command and service module on the Saturn IB rocket, and lasted 59 days, 11 hours and 9 minutes. A total of 1,084.7 astronaut-utilization hours were tallied by the Skylab 3 crew performing scientific experiments in the areas of medical activities, solar observations, Earth resources, and other experiments.

The crewed Skylab missions were officially designated Skylab 2, 3, and 4. Mis-communication about the numbering resulted in the mission emblems reading "Skylab I", "Skylab II", and "Skylab 3" respectively...

During the approach phase, a propellant leak developed in one of the Apollo Service Module's reaction control system thruster quads. The crew was able to safely dock with Skylab, but troubleshooting continued with the problem. Six days later, another thruster quad developed a leak, creating concern amongst Mission Control. For the first time, an Apollo spacecraft would be rolled out to Launch Complex 39 for a rescue mission, made possible by the ability for the station to have two Apollo CSMs docked at the same time. It was eventually determined that the CSM could be safely maneuvered using only two working thruster quads, and the rescue mission was never launched...

The crew, during their first EVA, installed the twin-pole sunshade, one of the two solutions for the destruction of the micrometeoroid shield during Skylab's launch to keep the space station cool. It was installed over the parasol, which was originally deployed through a porthole airlock during Skylab 2. Both were brought to the station by Skylab 2...

The S150 X-ray experiment was sent up with Skylab 3. The 1,360 kg X-ray astronomy satellite experiment was designed to look for soft galactic x-rays. Short missions had been done before, and S150 would be a longer project. S150 had a large soft x-ray detector, and was mounted atop the Saturn S-IVB upper stage. When released, S150 flew behind and below Skylab on 28 July 1973. The S150 experiment deployed after the Apollo capsule separated from the S-IVB stage. S150 had its own protective housing for the flight. The experiment on S150 ran for 5 hours, as its batteries allowed S150 to measure half of the sky. Experiment data was recorded on tape-recorder and sent to ground stations when available. S150 was designed by University of Wisconsin scientists Dr. William L. Kraushaar and Alan Bunner. S150 could detect 40-100 angstrom photons. The 2001 Wilkinson Microwave Anisotropy Probe gave a more detailed soft galactic X-ray map, confirming the S150 Galactic X-Ray Mapping finding...
