This photographs shows technicians positioning the Skylab Orbital Workshop (OWS) on a rotating work dolly during the assembly phase of the OWS at the McDornell Douglas facility in California. The OWS was the living and working quarters for the astronauts. The Marshall Space Flight Center (MSFC) had responsibility for developing and integrating most of the major components of the Skylab: the Orbital Workshop (OWS), Airlock Module (AM), Multiple Docking Adapter (MDA), Apollo Telescope Mount (ATM), Payload Shroud (PS), and most of the experiments.

This photograph is an interior view of the Orbital Workshop (OWS) upper level looking from the airlock hatch, showing the octagonal opening that separated the workshop's two levels. The trash airlock can be seen at center. The lower level of the OWS provided crew accommodations for sleeping, food preparation and consumption, hygiene, waste processing and disposal, and performance of certain experiments. The upper level consisted of a large work area and housed water storage tanks, a food freezer, storage vaults for film, scientific airlocks, mobility and stability experiment equipment, and other experimental equipment.

This photograph was taken during assembly of the bottom and upper floors of the Skylab Orbital Workshop (OWS). The OWS was divided into two major compartments. The lower level provided crew accommodations for sleeping, food preparation and consumption, hygiene, waste processing and disposal, and performance of certain experiments. The upper level consisted of a large work area and housed water storage tanks, a food freezer, storage vaults for film, scientific airlocks, mobility and stability experiment equipment, and other experimental equipment.

Assembling activities of the Skylab cluster are shown in this photograph. The Orbital Workshop (OWS) was lowered for joining to aft skirt and placed over the thrust structure inside the assembly tower. The OWS provided living and working quarters for the Skylab crew and the thruster provided short-term attitude control of the Skylab. The Marshall Space Flight Center had responsibilities for the design and development of the Skylab hardware, and management of experiments.

This wide-angle view depicts the Orbital Workshop (OWS) wardroom/galley located in the lower level of the OWS. The galley in the wardroom provided the daily supply of food; galley-located equipment was used for preparation and disposal of food. The Skylab astronauts used the wardroom as kitchen and dining room. The hexagonal food table, shown in the middle of this image, allowed three crewmen to simultaneously heat their food and eat their meals in an efficient and comfortable marner. Chairs were pointless in the zero-gravity environment. The table also supported components of the water system, including the water chiller and the wardroom water heater.

This cutaway illustration shows the characteristics and basic elements of the Skylab Orbiter Workshop (OWS). The OWS was divided into two major compartments. The lower level provided crew accommodations for sleeping, food preparation and consumption, hygiene, waste processing and disposal, and performance of certain experiments. The upper level consisted of a large work area and housed water storage tanks, a food freezer, storage vaults for film, scientific airlocks, mobility and stability experiment equipment, and other experimental equipment. The compartment below the crew quarters was a container for liquid and solid waste and trash accumulated throughout the mission. A solar array, consisting of two wings covered on one side with solar cells, was mounted outside the workshop to generate electrical power to augment the power generated by another solar array mounted on the solar observatory. Thrusters were provided at one end of the workshop for short-term control of the attitude of the space station.

This wide-angle view is of the Orbital Workshop (OWS) sleep compartment, located in the lower level of the OWS. Each crewman was assigned a small space for sleeping and zipped themselves into sleeping bags stretched against the wall. Because of the absence of gravity, sleeping comfort was achieved in any position relative to the spacecraft; body support was not necessary. Sleeping could be accommodated quite comfortably in a bag that held the body at a given place in Skylab.

This photograph shows activities during assembly of the Skylab cluster at the Vehicle Assembly/Checkout building. The Saturn V S-IVB stage is shown at left, and right is the Orbital Workshop (OWS) being readied for mating to the thruster. The S-IVB stage was modified to house the OWS, which provided living and working quarters for the Skylab crews. The Marshall Space Flight Center had responsibilities for the design and development of the Skylab hardware, and management of experiments.

Engineers from the Marshall Space Flight Center (MSFC) and its contractors were testing the twin-pole sunshade at the Skylab mockup in the MSFC Building 4619. The Skylab Orbital Workshop (OWS) lost its thermal protection shield during launch on May 14, 1963. Without the heat shield, the temperature inside the OWS became dangerously high, rendering the workshop uninhabitable and threatened deterioration of the interior insulation and adhesive. Engineers from the MSFC, its contractors, and NASA persornel at other centers worked day and night for several days to develop the way to save the Skylab OWS. Eventually, they 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 shows the Skylab Orbital Workshop (OWS) assembled, with its Thruster Attitude Control System (TACS) and radiator, ready for placing on the transporter. Twenty-two titanium spheres above the radiator housed the nitrogen required for operation of the TACS. At one end of the OWS, the TACS provided short-term control of the attitude of the Skylab.

This photograph was taken during installation of floor grids on the upper and lower floors inside the Skylab Orbital Workshop at the McDornell Douglas plant at Huntington Beach, California. The OWS was divided into two major compartments. The lower level provided crew accommodations for sleeping, food preparation and consumption, hygiene, waste processing and disposal, and performance of certain experiments. The upper level consisted of a large work area and housed water storage tanks, a food freezer, storage vaults for film, scientific airlocks, mobility and stability experiment equipment, and other experimental equipment.

This is a close-up photograph of the Orbital Workshop (OWS) trash disposal airlock located on the floor of the lower level of the OWS. It provided a means of passing trash from the pressurized habitable area into the unpressurized waste tank. The crewman opened a valve which brought the airlock to the same pressure as that within the workshop. He then opened the lid, placed the bagged trash inside, closed the lid and locked it. By turning the valve handle, he reduced the pressure within the airlock until it reached the vacuum of the waste tank. The crewman then operated an ejector handle that caused a scissors-type mechanism to push the bagged trash from the airlock into the tank.

This image, with callouts, depicts the storage area of the forward compartment at the upper level of the Orbital Workshop (OWS). The upper level consisted of a large work area and housed water storage tanks, a food freezer, storage vaults for film, scientific airlocks, mobility and stability experiment equipment, and other experimental equipment.

This photograph was taken at the Redstone airfield, Huntsville, Alabama, during the unloading of the Saturn V S-IVB stage that housed the Orbital Workshop (OWS) from the Super Guppy, the NASA plane that was specially built to carry oversized cargo. The OWS measured 22 feet (6.7 m) in diameter, and 48 feet (14.6 m) in length. The Saturn V S-IVB stage was modified at the McDornell Douglas facility at Huntington Beach, California, for a new role, which was to house the OWS. In addition to the test articles, engineering mockups, and flight equipment, both McDonnell Douglas and Martin Marietta built 0-G trainers, neutral buoyancy trainers, and high-fidelity mockups for the 1-G trainer to be used in the KC-135 aircraft. The Marshall Space Flight Center had program management responsibility for the development of Skylab hardware and experiments.

Two seamstresses stitch together a sun-shade for Skylab Orbital Workshop (OWS), the first U.S. experimental space station in orbit, which lost its thermal protection shield during the launch on May 14, 1973. Without the heat shield, the temperature inside the Orbital Workshop became dangerously high, rendering the workshop uninhabitable and threatened deterioration of the interior insulation and adhesive. Engineers and scientists at Marshall Space Flight Center (MSFC) worked tirelessly around the clock on the emergency repair procedure. The Skylab crew and the repair kits were launched just 11 days after the incident. The crew successfully deployed the twin-pole sail parasol sun-shade during their EVA (Extravehicular Activity) the next day.

This series of 41 radar images obtained by the Deep Space Network's Goldstone Solar System Radar on July 28, 2025, shows the near-Earth asteroid 2025 OW as it made its close approach with our planet. The asteroid safely passed at about 400,000 miles (640,000 kilometers), or 1.6 times the distance from Earth to the Moon. The asteroid was discovered on July 4, 2025, by the NASA-funded Pan-STARRS2 survey telescope on Haleakala in Maui, Hawaii. These Goldstone observations suggest that 2025 OW is about 200 feet (60 meters) wide and has an irregular shape. The observations also indicate that it is rapidly spinning, completing one rotation every 1½ to 3 minutes, making it one of the fastest-spinning near-Earth asteroids that the powerful radar system has observed. The observations resolve surface features down to 12 feet (3.75 meters) wide. Asteroids can be "spun up" by sunlight being unevenly absorbed and re-emitted across their irregular surfaces. As photons (quantum particles of light) carry a tiny amount of momentum away from the asteroid, a tiny amount of torque is applied and, over time, the asteroid's spin can increase – a phenomenon known as the YORP effect. For 2025 OW to maintain such a fast rotation without breaking apart, it may be a solid object rather than a loosely bound rubble pile like many asteroids. The Goldstone measurements have allowed scientists to greatly reduce uncertainties in the asteroid's distance from Earth and in its future motion for many decades. This July 28 close approach is the closest asteroid 2025 OW will come to Earth for the foreseeable future. Animation available at https://photojournal.jpl.nasa.gov/catalog/PIA26587

This image is a wide-angle view of the Orbital Workshop waste management compartment. The waste management facilities presented a unique challenge to spacecraft designers. In addition to collection of liquid and solid human wastes, there was a medical requirement to dry all solid human waste products and to return the residue to Earth for examination. Liquid human waste (urine) was frozen for return to Earth. Total quantities of each astronaut's liquid and solid wastes were precisely measured. Cabin air was drawn into the toilet, shown on the wall at right in this photograph, and over the waste products to generate a flow of the waste in the desired direction. The air was then filtered for odor control and antiseptic purposes prior to being discharged back into the cabin.

In this photograph, the Orbital Workshop shower compartment was unfolded by technicians for inspection. The shower compartment was a cylindrical cloth enclosure that was folded flat when not in use. The bottom ring of the shower was fastened to the floor and contained foot restraints. The upper ring contained the shower head and hose. To use the shower, the astronaut filled a pressurized portable bottle with heated water and attached the bottle to the ceiling. A flexible hose cornected the water bottle to a handheld shower head. The astronaut pulled the cylindrical shower wall up into position and bathed, using liquid soap. Both soap and water were carefully rationed, having been premeasured for economical use.

This is a wide-angle view of the Orbital Workshop lower level experiment area. In center foreground is the ergometer bicycle. In center background is a litter chair for the Human Vestibular Function experiment (Skylab Experiment M131) and in right background is the Lower Body Negative Pressure System experiment (Skylab Experiment M092). The ergometer bicycle was used for metabolic activity experiments and exercise. The purpose of the Human Vestibular (irner ear) Function experiment was to examine the effect of weightlessness on man's sensitivity and susceptibility to motion rotation, and his perception of orientation. The Lower Body Negative Pressure experiment investigated the relationship between the zero gravity environment and cardiovascular deconditioning. A characteristic of cardiovascular deconditoning is the partial failure of the blood vessels resulting in the excessive pooling of the blood in the legs when a person assumes an erect posture in a gravity field. The Marshall Space Flight Center had the program management responsibility for the development of Skylab hardware and experiments.
