KENNEDY SPACE CENTER, FLA. - A KSC employee uses a clean-air shower before entering a clean room. Streams of pressurized air directed at the occupant from nozzles in the chamber's ceiling and walls are designed to dislodge particulate matter from hair, clothing and shoes. The adhesive mat on the floor captures soil from shoe soles, as well as particles that fall on its surface. Particulate matter has the potential to contaminate the space flight hardware being stored or processed in the clean room. The shower is part of KSC's Foreign Object Debris (FOD) control program, an important safety initiative.

Josh Litofsky leads a Gateway lunar dust adhesion testing campaign at NASA’s Johnson Space Center in Houston. His team studies how lunar dust interacts with materials chosen for Gateway's construction. Here, Litofsky carefully positions a sample holder inside a vacuum chamber. Litofksy’s work seeks to validate the Gateway On-orbit Lunar Dust Modeling and Analysis Program (GOLDMAP), developed by Ronald Lee, also of Johnson Space Center. By considering factors such as the design and configuration of the space station, the materials used, and the unique conditions in lunar orbit, GOLDMAP helps predict how dust may move and settle on Gateway’s external surfaces.

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.

KENNEDY SPACE CENTER, FLA. -- In the Orbiter Processing Facility, United Space Alliance employee Harrell Watts applies RTV, a room-temperature vulcanizing silicone adhesive, to a main landing gear door of Space Shuttle orbiter Enterprise (OV-101) on which Thermal Protection System tiles are being installed. Sections of Enterprise were borrowed from the Smithsonian Institution's Air and Space Museum where the orbiter is being stored at the Washington Dulles International Airport. Enterprise was the first orbiter built in the Shuttle fleet and was used to conduct the Approach and Landing Test Program before the first powered Shuttle flight. After the tile installation is complete, the sections will be transferred to the Southwest Research Institute for testing requested by the Columbia Accident Investigation Board.
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 image, received today, shows the trench excavated by NASA's Viking 1 surface sampler. The trench was dug by extending the surface sampler collection head in a direction from lower right toward the upper left and then withdrawing the surface sampler collector head. Lumpy piles of material at end of trench at lower right was pulled by plowing from trench by the backhoe which will be used to dig trenches later in the mission. Area around trench has ripple marks produced by Martian wind. The trench which was dug early on Sol 8, is about 3 inches wide, 2 inches deep and 6 inches long. Steep dark crater walls show the grains of the Martian surface material stick together (have adhesion). The doming of the surface at far end of the trench show the granular material is dense. The Martian surface material behaves somewhat like moist sand on Earth. Evidence from the trench indicate a sample was collected and delivered to the experiments after repeated tries. The biology experiment level full indicator indicates a sample was received for analysis. The X-Ray fluorescence experiment has no indication to show it received a sample. The GCMS experiment level full indicator suggests no sample was received but this matter is being investigated. http://photojournal.jpl.nasa.gov/catalog/PIA00389
John Marshall, an investigator at Ames Research Center and a principal investigator in the microgravity fluid physics program, is studying the adhesion and cohesion of particles in order to shed light on how granular systems behave. These systems include everything from giant dust clouds that form planets to tiny compressed pellets, such as the ones you swallow as tablets. This knowledge should help us control the grains, dust, and powders that we encounter or use on a daily basis. Marshall investigated electrostatic charge in microgravity on the first and second U.S. Microgravity Laboratory shuttle missions to see how grains aggregate, or stick together. With gravity's effects eliminated on orbit, Marshall found that the grains of sand that behaved ever so freely on Earth now behaved like flour. They would just glom together in clumps and were quite difficult to disperse. That led to an understanding of the prevalence of the electrostatic forces. The granules wanted to aggregate as little chains, like little hairs, and stack end to end. Some of the chains had 20 or 30 grains. This phenomenon indicated that another force, what Marshall believes to be an electrostatic dipole, was at work.(The diagram on the right emphasizes the aggregating particles in the photo on the left, taken during the USML-2 mission in 1995.)
W. Brian Dunlap of Youngstown, Ohio, proposed Skylab student experiment ED-78, Liquid Motion in Zero-G, a study of wave motion in a liquid. He was particularly interested in comparing surface waves over a liquid in zero-gravity with those occurring on Earth. In space, with the absence of gravity, a liquid does not necessarily take the shape of its container as it does on Earth. Adhesion forces may hold the liquid in contact with its container, but the liquid can also assume a free-floating condition. It was in this latter state that Dunlap wished to examine the behavior of surface waves. Data were recorded on videotape and subsequently converted to 16-mm film. Dunlap analyzed these data to determine periods of oscillation of free-floating globules and found agreement with the theory to be much better than expected. In March 1972, NASA and the National Science Teachers Association selected 25 experiment proposals for flight on Skylab. Science advisors from the Marshall Space Flight Center aided and assisted the students in developing the proposals for flight on Skylab.
Technicians set up test hardware inside the test section of the Icing Research Tunnel at the National Aeronautics and Space Administration (NASA) Lewis Research Center. The Icing Research Tunnel was built in the early 1940s to study the formation of ice on aircraft surfaces and develop methods of preventing or eradicating that ice. Ice buildup is dangerous because it adds extra weight, effects aerodynamics, and sometimes blocks air flow through engines. The Icing Research Tunnel is a closed-loop atmospheric wind tunnel with a 6- by 9-foot test section. The tunnel can produce speeds up to 300 miles per hour and temperatures from 30 to -45 °F. NACA engineers struggled initially to perfect a spray bar system to introduce moisture into the airstream. The tunnel was shut down in the late 1950s as the center focused its energy exclusively on space. Industrial customers began using the tunnel sporadically, then steadily, in the 1960s. Boeing, Aerojet, Lockheed, Sikorsky, Beech and others ran tests during the 1960s. Boeing analyzed engine inlets for the CH-47 Chinook, CH-46 (Sea Knight) and CH-113. This photograph was taken during a series of 100 ice-phobic coatings for the Federal Aviation Administration. They found that many of the coatings reduced ice adhesion to the test sample, but they could not be used for aircraft applications.
