Aeronautics and Space Administration (NASA) Lewis Research Center. Aerojet General was contracted to design the SNAP-8 generator which employed a mercury Rankine system to convert the reactor’s heat into electrical power. The hermetically-sealed pump was designed to generate from 35 to 90 kilowatts of electrical power. In 1964 a SNAP-8 test rig with a mercury boiler and condenser was set up in cell W-1 of Lewis’ Engine Research Building to study the transients in the system’s three loops. In 1967 a complete Rankine system was operated for 60 days in W-1 to verify the integrity of the Lewis-developed mercury boiler. Further tests in 1969 verified the shutdown and startup of the system under normal and emergency conditions. Aerojet operated the first full-Rankine system in June 1966 and completed a 2500-hour endurance test in early 1969. Lewis and Aerojet’s success on the Rankine system was acknowledged with NASA Group Achievement Award in November 1970. The 1970 vibration tests, seen here, were conducted in Lewis’ Engine Research Building’s environmental laboratory. The testing replicated the shock and vibration expected to occur during the launch into space and subsequent maneuvering. The pump was analyzed on each of its major axes.

This photograph was taken after Dr. von Braun moved from his post as Director of the Marshall Space Flight Center (MSFC) to Deputy Associate Administrator for Plarning at NASA Headquarters. On June 27, 1970, he visited the MSFC again to look at a mockup of the spacecraft that would later be known as Skylab. Others in the photograph are, from left to right, James R. Thompson, David Newby, Karl Heimburg, Hermann Weidner, and Jack Stockes. Years later, Thompson would serve as Director of the MSFC.

Managed by Marshall Space Flight Center, the Space Tug concept was intended to be a reusable multipurpose space vehicle designed to transport payloads to different orbital inclinations. Utilizing mission-specific combinations of its three primary modules (crew, propulsion, and cargo) and a variety of supplementary kits, the Space Tug would have been capable of numerous space applications. This 1970 illustration depicts the primary modules of the Space Tug system along with some of the supplementary kits: lunar landing legs, extendable support arms, astrionics, and the satellite probe. The Space Tug program was cancelled and did not become a reality.

This illustration shows general characteristics of the Skylab with callouts of its major components. In an early effort to extend the use of Apollo for further applications, NASA established the Apollo Applications Program (AAP) in August of 1965. The AAP was to include long duration Earth orbital missions during which astronauts would carry out scientific, technological, and engineering experiments in space by utilizing modified Saturn launch vehicles and the Apollo spacecraft. Established in 1970, the Skylab Program was the forerurner of the AAP. The goals of the Skylab were to enrich our scientific knowledge of the Earth, the Sun, the stars, and cosmic space; to study the effects of weightlessness on living organisms, including man; to study the effects of the processing and manufacturing of materials utilizing the absence of gravity; and to conduct Earth resource observations. The Skylab also conducted 19 selected experiments submitted by high school students. Skylab's 3 different 3-man crews spent up to 84 days in Earth orbit. 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. MSFC was also responsible for providing the Saturn IB launch vehicles for three Apollo spacecraft and crews and a Saturn V launch vehicle for the Skylab.

In this artist's concept from 1970, propulsion concepts such as the Nuclear Shuttle and Space Tug are shown in conjunction with other proposed spacecraft. As a result of the recommendations from President Nixon's Space Task Group for more commonality and integration in the American space program, Marshall Space Flight engineers studied many of the spacecraft depicted here.

Researchers at the Lewis Research Center had been studying different methods of electric rocket propulsion since the mid-1950s. Harold Kaufman created the first successful engine, the electron bombardment ion engine, in the early 1960s. Over the ensuing decades Lewis researchers continued to advance the original ion thruster concept. A Space Electric Rocket Test (SERT) spacecraft was launched in June 1964 to test Kaufman’s engine in space. SERT I had one cesium engine and one mercury engine. The suborbital flight was only 50 minutes in duration but proved that the ion engine could operate in space. This was followed in 1966 by the even more successful SERT II, which operated on and off for over ten years. Lewis continued studying increasingly more powerful ion thrusters. These electric engines created and accelerated small particles of propellant material to high exhaust velocities. Electric engines have a very small amount of thrust and are therefore not capable of lifting a spaceship from the surface of the Earth. Once lofted into orbit, however, electric engines are can produce small, continuous streams of thrust for several years.

S70-34852 (11 April 1970) --- The Apollo 13 (Spacecraft 109/Lunar Module 7/Saturn 508) space vehicle is launched from Pad A Launch Complex 39, Kennedy Space Center (KSC), at 2:13 p.m. (EST), April 11, 1970. The crew of the National Aeronautics and Space Administration's (NASA) third lunar landing mission are astronauts James A. Lovell Jr., commander; John L. Swigert Jr., command module pilot; and Fred W. Haise Jr., lunar module pilot.

This 1970 photograph shows Skylab's Ultraviolet (UV) Airglow Horizon Photography experiment. It was an astrophysics investigation designed to photograph the twilight airflow and Earth's ozone layer simultaneously in visible and UV wavelengths. These observations provided information on oxygen, nitrogen, and ozone layers in the Earth's atmosphere, and on their variation during night and day cycles. The Marshall Space Flight Center had program management responsibility for the development of Skylab hardware and experiments.

This 1970 photograph shows the Skylab's Ultraviolet (UV) Spectrograph, an Apollo Telescope Mount instrument. Its telescope, with camera and TV capability, photographed the Sun in selected ultraviolet wavelengths. The spectrograph was used to record the spectrum of UV emissions, such as flares or filaments, from a small individual feature on the solar disc. Real-time TV was used by the crew to monitor the performance of the telescope, transmit to the ground, and record. The exposed films were retrieved by astronaut extravehicular activities. The Marshall Space Flight Center had program management responsibility for the development of the Skylab hardware and experiments.

Apollo 13 onboard photo: This view of the severely damaged Apollo 13 Service Module was photographed from the Lunar Module/Command Module following the jettison of the Service Module. As seen here, an entire panel of the Service Module was blown away by the apparent explosion of oxygen tank number two located in Sector 4 of the Service Module. Two of the three fuel cells are visible just forward (above) the heavily damaged area. Three fuel cells, two oxygen tanks, and two hydrogen tanks, are located in Sector 4. The damaged area is located above the S-band high gain anterna. Nearest the camera is the Service Propulsion System (SPS) engine and nozzle. The damage to the Service Module caused the Apollo 13 crewmen to use the Lunar Module as a lifeboat. The Lunar Module was jettisoned by the Command Module just prior to Earth re-entry.

Shown here is the Skylab food heating and serving tray with food, drink, and utensils. The tray contained heating elements for preparing the individual food packets. The food on Skylab was a great improvement over that on earlier spaceflights. It was no longer necessary to squeeze liquified food from plastic tubes. Skylab's kitchen in the Orbital Workshop wardroom was so equipped that each crewman could select his own menu and prepare it to his own taste. The Marshall Space Flight Center had program management responsibility for the development of Skylab hardware and experiments.

S70-38747 (11 April 1970) --The Apollo 13 (Spacecraft 109/Lunar Module 7/Saturn 508) space vehicle is launched from Pad A, Launch Complex 39, Kennedy Space Center (KSC), at 2:13 p.m. (EST), April 11, 1970.

Haise Jr., lunar module pilot.

AS13-59-8562 (17 April 1970) --- This view of the Apollo 13 Lunar Module (LM) was photographed from the Command Module (CM) just after the LM had been jettisoned. The jettisoning occurred a few minutes before 11 a.m. (CST), April 17, 1970, just over an hour prior to splashdown of the CM in the south Pacific Ocean. The apparent explosion of oxygen tank number two in the Apollo 13 Service Module (SM) caused the Apollo 13 crew members to rely on the LM as a "lifeboat".

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.

As part of the Space Task Group's recommendations for more commonality and integration in America's space program, Marshall Space Flight Center engineers proposed the use of a Nuclear Shuttle in conjunction with a space station module, illustrated in this 1970 artist's concept, as the basis for a Mars excursion module.

This 1970 photograph shows Skylab's Infrared Spectrometer Viewfinder Tracking System, a major component of an Earth Resources Experiment Package (EREP). It was designed to evaluate Earth resources sensors for specific regions of the the visible and infrared spectra and assess the value of real time identification of ground sites. The overall purpose of the EREP was to test the use of sensors that operated in the visible, infrared, and microwave portions of the electromagnetic spectrum to monitor and study Earth resources. The Marshall Space Flight Center had program management responsibility for the development of Skylab hardware and experiments.

The heat flow experiment on Apollo 13 will have an electronic instrument which will measure the outward flux of heat from the moon?s interior.

This photograph shows Skylab's Galactic X-Ray Mapping facility (S150), an astrophysics and space sciences investigation. An objective of this experiment was to extend the search for the origin of galactic x-rays beyond the sensitivity possible with short flights of small research rockets. This was accomplished by placing a large-area, soft x-ray detector in orbit to collect data for a much longer time. The S150 instrument was not in Skylab but in the instrument unit of the second stage of the Skylab-3 Saturn IB rocket.

Donald Rhodes, left, and Clyde Greer, right, monitor the operation of the National Aeronautics and Space Administration’s (NASA) Plum Brook Reactor Facility from the control room. The 60-megawatt test reactor, NASA’s only reactor, was the eighth largest test reactor in the world. The facility was built by the Lewis Research Center in the late 1950s to study the effects of radiation on different materials that could be used to construct nuclear propulsion systems for aircraft or rockets. The reactor went critical for the first time in 1961. For the next two years, two operators were on duty 24 hours per day working on the fission process until the reactor reached its full-power level in 1963. Reactor Operators were responsible for monitoring and controlling the reactor systems. Once the reactor was running under normal operating conditions, the work was relatively uneventful. Normally the reactor was kept at a designated power level within certain limits. Occasionally the operators had to increase the power for a certain test. The shift supervisor and several different people would get together and discuss the change before boosting the power. All operators were required to maintain a Reactor Operator License from the Atomic Energy Commission. The license included six months of training, an eight-hour written exam, a four-hour walkaround, and testing on the reactor controls.

This 1970 photograph shows Skylab's In-Flight Lower Body Negative Pressure experiment facility, a medical evaluation designed to monitor changes in astronauts' cardiovascular systems during long-duration space missions. This experiment collected in-flight data for predicting the impairment of physical capacity and the degree of orthostatic intolerance to be expected upon return to Earth. Data to be collected were blood pressure, heart rate, body temperature, vectorcardiogram, lower body negative pressure, leg volume changes, and body mass. The Marshall Space Flight Center had program management responsibility for the development of Skylab hardware and experiments.

Official portrait of Marshall's second Center Director Dr. Eberhard F. Rees (1970-1973).

Skylab's Body Mass Measurement chair, the facility of the Body Mass Measurement experiment (M172), is shown here in this 1970 photograph. The M172 experiment determined the body mass of each crew member and observed changes in body masses during flight. Knowledge of exact body mass variations throughout the flight in significantly aided in the correlation of other medical data obtained during the flight. Mass measurements under zero-gravity conditions were achieved by the application of Newton's second law (force equals mass times acceleration). The Marshall Space Flight Center had program management responsibility for the development of Skylab hardware and experiments.
