Comparison of Germanium Telluride (GeTe) Crystals grown on Earth (left) and in space (right) during the Skylab SL-3 mission. These crystals were grown using a vapor transport crystal growth method in the Multipurpose Electric Furnace System (MEFS). Crystals grown on earth are needles and platelettes with distorted surfaces and hollow growth habits. The length of the ground-based needle is approximately 2 mm and the average lenth of the platelets is 1 mm. The dull appearance of the Skylab crystals resulted from condensation of the transport agent during the long cooling period dictated by the Skylab furnace. In a dedicated process, this would be prevented by removing the ampoule from the furnace and quenching the vapor source.

This chart describes the Hydrogen-Alpha (H-Alpha) #1 Telescope, one of eight major solar study facilities on the Skylab Apollo Telescope Mount (ATM). There were two H-Alpha telescopes on the ATM that were used primarily to point the ATM and keep a continuous photographic record during the solar observation periods. Both telescopes gave the Skylab astronauts a real-time picture of the Sun in the red light of the H-Alpha spectrum through a closed-circuit television. The H-Alpha #1 Telescope provided simultaneous photographic and ultraviolet (UV) pictures, while the #2 Telescope operated only in the TV mode. The Marshall Space Flight Center was responsible for development of the H-Alpha Telescopes.

SL2-X7-615 (22 June 1973) --- An overhead view of the Skylab 1 space station cluster in Earth orbit photographed from the Skylab 2 Command/Service Module during the final ?fly around? inspection by the CSM. The space station is sharply contrasted against a black sky background. Note the deployed parasol solar shield which shades the Orbital Workshop where the micrometeoroid shield is missing. The one remaining OWS solar array system wing has been fully deployed successfully. The OWS solar panel on the opposite side is missing completely. Photo credit: NASA

The Saturn V vehicle, carrying the unmarned orbital workshop for the Skylab-1 mission, lifted off successfully and all systems performed normally. Sixty-three seconds into flight, engineers in the operation support and control center saw an unexpected telemetry indication that signalled that damages occurred on one solar array and the micrometeoroid shield during the launch. The micrometeoroid shield, a thin protective cylinder surrounding the workshop protecting it from tiny space particles and the sun's scorching heat, ripped loose from its position around the workshop. This caused the loss of one solar wing and jammed the other. Still unoccupied, the Skylab was stricken with the loss of the heat shield and sunlight beat mercilessly on the lab's sensitive skin. Internal temperatures soared, rendering the the station uninhabitable, threatening foods, medicines, films, and experiments. This image shows the sun-ravaged skin of the Orbital Workshop, bared by the missing heat shield, with blister scars and tarnish from temperatures that reached 300 degrees F. The rectangular opening at the upper center is the scientific airlock through which the parasol to protect the workshop from sun's rays was later deployed. This view was taken during a fly-around inspection by the Skylab-2 crew. The Marshall Space Flight Center had a major role in developing the procedures to repair the damaged Skylab.

S73-26047 (18 May 1973) --- A sail-like sunshade for possible use as a sunscreen for the Skylab orbital workshop (OWS) is shown being fabricated in the GE Building across the street from the Johnson Space Center. Three persons assist the seamstress feed the material through the sewing machine. The three-layered shade will be composed of a top layer of aluminum Mylar, a middle layer of laminated nylon rip stop, and a bottom layer of thin nylon. Working on the sunshade, from left to right, are Dale Gentry, Elizabeth Gauldin, Alyene Baker and James H. Barnett Jr. Mrs. Baker, a GE employee, operates the double-needle sewing machine. Barnett is head of the Crew Equipment Development Section of JSC's Crew Systems Division. Mrs. Gauldin is also with the Crew Systems Division. Gentry works for GE. The work shown here is part of the crash program underway to prepare a protection device for Skylab to replace the original shield which was lost when the unmanned Skylab 1 launch took place on May 14, 1973. The improvised solar shield selected to be used will be carried to Earth orbit by the Skylab 2 crew, who will deploy it to shade part of the OWS from the hot rays of the sun. Loss of the original shield, as expected, has caused an overheating problem on the OWS. Photo credit: NASA
