Shortly after liftoff on May 14, 1973, atmospheric drag tore off the thin metallic shield of Skylab that was designed to protect her from micro-meteorites and the Sun's intense heat. The Skylab-2 crew deployed a parasol sunshield to protect the orbiting laboratory. Concern over the possibility that materials used for the parasol would deteriorate with prolonged exposure to the Sun's rays prompted the installation of a second sunshield during the Skylab-3 mission. This time, the crew exited the space station and installed a twin-pole device to position the shield over the parasol. This photograph was taken by the Skylab-4 mission.

Sixty-three seconds after the launch of the modified Saturn V vehicle carrying the Skylab cluster, 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. 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. The launch of the first marned Skylab (Skylab-2) mission was delayed until methods were devised to repair and salvage the workshop. Personnel from other NASA Centers and industries quickly joined the Marshall Space Flight Center (MSFC) in efforts to save the damaged Skylab. They worked day and night for the next several days. Eventually the MSFC developed, tested, rehearsed, and approved three repair options. These options included a parasol sunshade and a twin-pole sunshade to restore the temperature inside the workshop, and a set of metal cutting tools to free the jammed solar panel. This photograph was taken during a discussion of the methods of the twin-pole Sun shield by (left to right) Astronaut Alan Bean, MSFC Director Dr. Rocco Petrone, Astronaut Edward Gibson, and MSFC engineer Richard Heckman. Dr. William Lucas, who became MSFC Director after Dr. Petrone left MSFC in March of 1974, is standing.

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 the 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 station uninhabitable, threatening foods, medicines, films, and experiments. This image, taken during a fly-around inspection by the Skylab-2 crew, shows the station's remaining solar panel jammed against its side. The Marshall Space Flight Center had a major role in developing the procedures to repair the damaged Skylab.

The astronaut in the background is Joseph P. Kerwin, Skylab 2 science pilot. Here, Conrad is pushing up on the Beam Erection Tether (BET) to raise the stuck solar panel. The solar wing is only partially deployed; an aluminum strap is believed to be holding it down. Note the cut aluminum angle. Attach points for the BET are on the vent module of the solar array beam. The other end of the BET is attached to the "A" frame supporting the Apollo Telescope Mount (ATM) which is out of view. The aluminum strapping is to be out first, freeing the solar array beam. Then, if the beam does not automatically deploy, Conrad will attempt to help by pulling on the BET. The automatic openers may have become too cold to open without assistance. A deployed solar panel of the ATM is at upper left. The EVA is scheduled for Thursday, June 7th. This concept is by artist Paul Fjeld. 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.

Skylab and Mir Space Stations: In 1964, design and feasibility studies were initiated for missions that could use modified Apollo hardware for a number of possible lunar and Earth-orbital scientific and applications missions. An S-IVB stage of a Saturn V launch vehicle was outfitted completely as a workshop. The Skylab 1 Orbital Workshop with its Apollo Telescope Mount was launched into orbit May 14, 1973. The Skylab 2, 3 and 4 missions, each with three-man crews, proved that humans could live and work in space for extended periods. The Shuttle-Mir Program was a joint effort between 1994-1998 which allowed American and Russian crews to share expertise and knowledge while working together in space. As preparation for the construction of the International Space Station, Shuttle-Mir encompassed 11 space shuttle flights and 7 astronaut residencies on the Russian space station Mir.

SL4-136-3388 (2 Dec. 1973) --- This excellent view of a South Pacific storm was photographed from the Skylab space station in Earth orbit by one of the Skylab 4 crewmen. The camera used was a hand-held 70mm Hasselblad, with SO-368 medium-speed Ektachrome film. This photograph of a low pressure area and associated frontal activity was taken for studying the development of such storm systems. The low sun angle enhances the relief, giving much of the picture a three-dimensional appearance. The good definition of the clouds with the cumulonimbus (thunderstorm clouds) penetrating the cirrus cloud layer makes this an interesting photograph to study. This storm, located east of New Zealand at 170 degrees west longitude and 50 degrees south latitude, is not and never became a typhoon. However, in some ways it may look similar. Photo credit: NASA

Internal temperatures soared, rendering the station uninhabitable, threatening foods, medicines, films, and experiments. This image, taken during a fly-around inspection by the Skylab-2 crew, shows the damaged meteoroid shield being held by a thin aluminum strap entangled with green-hued remnants of the lost heat shield. The Marshall Space Flight Center (MSFC) developed, tested, rehearsed, and approved three repair options. These options included a parasol sunshade and a twin-pole sunshade to restore the temperature inside the workshop, and a set of metal cutting tools to free the jammed solar panel.

This close up view of one of the two scientific airlocks on the Skylab Orbital Workshop Section was taken from the Skylab 2 Command/Service Module during its initial fly around inspection. The micrometeoroid shield can be seen to be missing from this section of the orbital workshop. A parasol solar shield was later devised and put in place over this damaged area through this very same airlock opening.

S73-36161 (November 1973) --- In the Radiation Counting Laboratory sixty feet underground at JSC, Dr. Robert S. Clark prepares to load pieces of iridium foil -- sandwiched between plastic sheets -- into the laboratory's radiation detector. The iridium foil strips were worn by the crew of the second Skylab flight in personal radiation dosimeters throughout their 59 1/2 days in space. Inside the radiation detector assembly surrounded by 28 tons of lead shielding, the sample will be tested to determine the total neutron dose to which the astronauts were exposed during their long stay aboard the space station.

SL4-138-3843 (1 Jan. 1974) --- A part of northern California centered near San Francisco Bay photographed at 3 p.m. Jan. 2, 1974, from the Skylab space station in Earth orbit. This near vertical view encompasses the coastline from Monterey Bay (right) to about 50 miles north of Point Reyes (left) and includes, from bottom to top, San Francisco Bay (center), Sacramento Valley (left center), San Joaquin Valley (right center), and the snow-covered Sierra Nevada. Afternoon shadows sharply delineate a valley which parallels San Francisco Bay, crosses Point Reyes, and lies between the Bay and the Pacific coastline. This valley marks the location of the San Andreas Fault, a major break in the Earth's crust. Forces acting on the crust are causing the land west (bottom) of the fault line to move north relative to land on the east side. The Skylab 4 astronauts photographed major fault zones in South America, New Zealand, Japan and Africa for use in the study of worldwide tectonic system. Agricultural areas in the Sacramento and San Joaquin Valleys are indicated by the tan areas which are easily discerned in contrast to the green-gray background. Photo credit: NASA

SL4-139-3953 (7 Jan. 1974) --- An oblique view of a portion of the Middle West looking northeastward toward Lake Superior and Ontario, Canada, as seen from the Skylab space station in Earth orbit. This picture was taken by one of the Skylab 4 crewmen with a hand-held 70mm Hasselblad camera using a 100mm lens. Most of the land mass in the foreground is Wisconsin. Iowa is in the lower left corner. Minnesota is at left and upper left. Ontario is in the far right background. Michigan is at right center. Note the circular-shaped feature at center left which was first observed by the Skylab 4 crewmen. The feature is 85 kilometers (55 miles) in diameter, and it is centered near 91.5 degrees west longitude and 44.5 degrees north latitude. The Mississippi River Valley forms the southwest side of the circular feature. The City of La Crosse, Wisconsin, is just south of the near side of the circle, and the Black River completes the southern and eastern part. The City of Eau Claire is at the north edge of the circle. The most likely origin of circular features of this magnitude are (1) volcanic, (2) structural, or (3) meteorite impact. The feature is not volcanic -- the rocks are the wrong type. Possibly it is structural, formed by slight warping of layered rocks into a basin or dome, followed by erosion of all but the most subtle trace of the structure. The feature could be a severely eroded meteorite impact crater. If so, a thorough study of the area may yield evidence of the extreme pressure and temperature the rocks were subjected to by the shock of an impacting meteorite. Photo credit: NASA

KENNEDY SPACE CENTER, FLA. -- Former astronaut Robert Crippen smiles at the warm greeting he is receiving when introduced as a previous inductee into the U.S. Astronaut Hall of Fame. He and other Hall of Fame members were present for the induction of five new space program heroes into the U.S. Astronaut Hall of Fame: Richard O. Covey, commander of the Hubble Space Telescope repair mission; Norman E. Thagard, the first American to occupy Russia’s Mir space station; the late Francis R. "Dick" Scobee, commander of the ill-fated 1986 Challenger mission; Kathryn D. Sullivan, the first American woman to walk in space; and Frederick D. Gregory, the first African-American to command a space mission and the current NASA deputy administrator. Crippen piloted the first Space Shuttle flight in 1981 and commanded three other Shuttle missions in the next 3-1/2 years. In the early 1990s he served as director of NASA’s Kennedy Space Center. The induction ceremony was held at the Apollo/Saturn V Center at KSC. The U.S. Astronaut Hall of Fame opened in 1990 to provide a place where space travelers could be remembered for their participation and accomplishments in the U.S. space program. The five inductees join 52 previously honored astronauts from the ranks of the Gemini, Apollo, Skylab, Apollo-Soyuz, and Space Shuttle programs.

SL3-88-222 (18 Sept. 1973) --- The metropolitan area of Chicago is encompassed in this Skylab 3 Earth Resources Experiments Package (EREP) S190-B photograph taken on Sept. 18, 1973 from the Skylab space station cluster in Earth orbit. The surrounding major cities of Aurora and Joliet, Illinois; Hammond, Gary and East Chicago, Indiana, are easily delineated. The photograph reveals the following: (1) Cultural differentiation of commercial, industrial and residential areas for use in population and social studies in micro-macro community planning and in cultural pattern studies in the improvement of urban areas. (Aurora is one of 27 census cities of interest to Robert Alexander, a principal investigator. Alexander is with the U.S. Geological Survey). (2) The transportation network with major corridors and their interchanges, primary and feeder streets for use in network analysis and in the development of models for population movement and land use projection. (3) The agricultural lands for land use identification on crop inventory analysis; airports for use in delineation of service and infringement of major man-made features that affect ecosystem balance (support to environmental impact studies). (4) Air and water plumes for use in case studies, natural and man-made differentiation of pollution sources, in support of model development and in ecosystem research studies on the effects of pollution. (5) Recreational centers for use in relating recreational centers to population centers, establishing possible demands and in development of possible future recreational centers to support the demand.
