Once the United States' space program had progressed from Earth's orbit into outerspace, the prospect of building and maintaining a permanent presence in space was realized. To accomplish this feat, NASA launched a temporary workstation, Skylab, to discover the effects of low gravity and weightlessness on the human body, and also to develop tools and equipment that would be needed in the future to build and maintain a more permanent space station. The structures, techniques, and work schedules had to be carefully designed to fit this unique construction site. The components had to be lightweight for transport into orbit, yet durable. The station also had to be made with removable parts for easy servicing and repairs by astronauts. All of the tools necessary for service and repairs had to be designed for easy manipulation by a suited astronaut. Construction methods had to be efficient due to the limited time the astronauts could remain outside their controlled environment. In lieu of all the specific needs for this project, an environment on Earth had to be developed that could simulate a low gravity atmosphere. A Neutral Buoyancy Simulator (NBS) was constructed by NASA Marshall Space Flight Center (MSFC) in 1968. Since then, NASA scientists have used this facility to understand how humans work best in low gravity and also provide information about the different kinds of structures that can be built. With the help of the NBS, building a space station became more of a reality. Pictured is Astronaut Paul Weitz training on a mock-up of Spacelab's airlock-hatch cover. Training was also done on the use of foot restraints which had recently been developed to help astronauts maintain their positions during space walks rather than having their feet float out from underneath them while they tried to perform maintenance and repair operations. Every aspect of every space mission was researched and demonstrated in the NBS. Using the airlock hatch cover and foot restraints were just a small example of the preparation that went into each mission.

Careful inspection of the photo proves that, actually, his floating is limited, as he has anchored his left foot with a special restraint device. He apparently has chosen this vantage point to use the Arriflex motion picture camera in his right hand.

S103-E-5347 (24 December 1999) --- Astronaut Steven L. Smith, payload commander, prepares to use a 35mm camera during the final space walk of the STS-103 mission.

51I-44-012 (1 Sept. 1985) --- Astronaut James D. van Hoften looks on as the Syncom IVC-3 satellite responds to his push against it moments earlier. Dr. van Hoften, mission specialist, is anchored to a foot restraint on the end of the remote manipulator system (RMS) arm of the Earth-orbiting space shuttle Discovery. The 51-I crew members showed this photograph at their Sept. 11 postflight press conference. Photo credit: NASA

STS-116 astronaut and mission specialist, Robert Curbeam, along with the European Space Agency’s (ESA) Christer Fuglesang (partially out of the frame), are anchored to the International Space Station’s Canadarm2 foot restraints. The two were working on the port overhead solar array wing on the Station’s P6 truss during the mission’s fourth session of Extra Vehicular Activity (EVA). For 6 hours and 38 minutes, the space walkers used specially prepared, tape insulated tools to guide the array wing neatly inside its blanket box.

He and fellow astronaut Andrew Morgan (out of frame) were conducting the second spacewalk to repair the International Space Station's cosmic particle detector, the Alpha Magnetic Spectrometer.

S84-27039 (7 Feb 1984) --- Astronaut Bruce McCandless II, at first glance appears to be walking on cargo in the Space Shuttle Challenger's payload bay. Actually, he is being "flown" around above the stationary cargo. His "flight" is due to the combined configuration of the Mobile Foot Restraint (MFR) and the Remote Manipulator System (RMS). His helmet visor reflects in miniature parts of the payload bay that can't be seen in the larger portion of the photo. A 70mm camera aimed through the aft flight deck windows exposed this frame.
