Images from space have many applications: e.g., they can be used to study global climates, land and sea formations, crop weather damage and health assessments. Special sensors can also provide important data regarding transient atmospheric and geologic phenomena (hurricanes and volcanic eruptions), as well as a test bed for collecting data for new sensor technology development. + Capabilities + Components + Features + Scientific Investigations + Science & Mission Systems + Vision For Exploration + Watch NASA TV + Marshall Space Flight Center + Want to work at NASA? The WORF design uses existing EXpedite the PRocessing of Experiments to Space Station (EXPRESS) Rack hardware which includes a Rack Interface Controller box for power and data connection, Avionics Air Assembly fan for air circulation within the rack, rack fire detection, and appropriate avionics to communicate with the ISS data network. The WORF will maximize the use of this window by providing sensors (cameras, multispectral and hyper-spectral scanners, camcorders and other instruments) to capture imagery of the Earth and space. WORF also provides attachment points for power and data transfer and the capability for multiple instruments to be mounted and used in the window simultaneously. WORF will include a means of preventing the formation of condensation on the interior surface of the window and a retractable bump shield to protect the interior window surface from impacts of loose tools and hardware being used in the payload area during the set-up and changeout of sensor packages by the crew. The interior of the WORF provides a non-reflective, light-tight environment to minimize stray reflections and glare off the window allowing use to payloads that are sensitive to extremely low energy phenomena such as auroras. An opaque fabric shroud can be attached to the front of the rack to allow crew members to work in the WORF without the problem of glare from the U.S. Lab interior lights. The high quality optical window is located on the nadir (Earth facing) side of the U.S. Destiny laboratory module. The window provides a view of 39.5 degrees forward along the axis of the ISS, 32.2 degrees aft, and a total of 79.1 degrees from starboard to port. The window is 508 cm (20 in) in diameter. The window is made up of an assembly of four separate panes. The outermost pane is a replaceable debris pane a little more than 1.0 cm (one third of an inch) thick. It is designed to protect the window from small orbital debris or micrometeoroids that might strike the station. If it is severely damaged, it can be replaced during an EVA. The two middle panes serve as the primary and secondary pressure windows, ensuring that the laboratory module stays pressurized. Each of these panes is 3.2 cm (1-1/4 in) thick. The innermost pane, a multi-layer scratch pane, is a little less than a 1.7 cm (half-inch) thick. The scratch pane has an integral heater element to prevent condensation from forming on the pressure panes, and has a special anti-scratch coating that protects against accidental bumps from camera lenses and other equipment during set-up work inside the WORF rack. Although the scratch pane can support normal photography, it is often necessary to remove the scratch pane during the operation of other high-resolution sensors. When the scratch pane is removed, the WORF provides a deployable metal and acrylic bump shield to protect the primary pressure panes while equipment is set up in front of the window. When the sensors are ready for use and the interior of the WORF rack has been secured with a hatch cover, the bump shield can be retracted using controls on the outside of the WORF rack, giving the cameras/sensors a clear view through the window to the Earth below. When the scratch pane (and its heater element) is removed, the WORF rack provides a variable air flow across the window to prevent condensation. When the WORF is not in use, when visiting spacecraft are docking with the ISS, or when the window is exposed to orbital ram conditions during special orientations of the ISS, the research lab window is protected by a metal cover on the outside of the Destiny lab module. This external window shutter pivots on hinges and is rotated open and closed by the crew using controls on the WORF rack. + Freedom of Information Act Curator: MITS Applications and Web + The President's Management Agenda Services + NASA Privacy Statement, Disclaimer & Accessibility Certification NASA Official: Ginger Flores Last Updated: 25 April 2015. + NASA Home + S&MS Home Components + Home The WORF design uses existing EXpedite the PRocessing of Experiments to Space Station (EXPRESS) Rack hardware which includes: a Rack Interface Controller (RIC), the command and control interface for rack subsystems; the Payload Ethernet Hub/Bridge (PEHB), the Ethernet interface to payloads; the EXPRESS Memory Unit (EMU),the solid state memory device (320 MB) used for System software files, and Configuration files; and the Solid State Power Controller Module (SSPCM) which provides 120 VDC output to the RIC, AAA fan, PEHB, and Area Smoke Detector, and which converts 120 VDC to 28 VDC for payloads. + Capabilities + Components + Features + Scientific Investigations + Science & Mission Systems + Vision For Exploration + Watch NASA TV + Marshall Space Flight Center + Want to work at NASA? + Freedom of Information Act Curator: MITS Applications and Web + The President's Management Agenda Services + NASA Privacy Statement, Disclaimer & Accessibility Certification NASA Official: Ginger Flores Last Updated: 25 April 2015. + NASA Home + S&MS Home Features + Home WORF is available for scientific and commercial payloads.

The rack provides a payload volume equivalent to 0.8 m3, and will be able to support up to 3 payloads simultaneously, depending on available resources and space available at the window. WORF will also provide access and equipment for crew-Earth observations, such as crew restraints and camera/camcorder brackets, and condensation prevention. The spectral properties of the window support remote sensing work. The reflective coating on the window absorbs UV radiation, but transmittance rises rapidly after 304 nm to > 90% in the visible and into the near infrared. Transmittance tails off after 800 nm, reaching zero at approximately 2600 nm. Corning Inc., Corning, N.Y., provided glass capable of supporting viewing with high-resolution telescopes. The glass panes were polished to a fine finish by Zygo Corp., Middlefield, Conn. The panes were coated by Optical Coating Lab Inc., Santa Rosa, Calif., with anti-reflection chemicals that block ultra-violet radiation from the sun. The coating also is electro-conductive to cut down on condensation. The glass is homogenous, free of color, been polished very smoothly and is flat. In addition, for extra protection, the outermost panel has a clamshell-like protective aluminum cover that can be closed from inside the station. + Freedom of Information Act Curator: MITS Applications and Web + The President's Management Agenda Services + NASA Privacy Statement, Disclaimer & Accessibility Certification NASA Official: Ginger Flores Last Updated: 25 April 2015..

  • The International Space Station (ISS) Is an Experiment in the Design, Development, and Assembly of an Orbital Space Facility. It
    The International Space Station (ISS) is an experiment in the design, development, and assembly of an orbital space facility. It serves as a elements habitat for its crew, a command post for orbital operations, and a port for the rendezvous and berthing of smaller orbiting vehicles. It functions as an orbital microgravity and life sciences laboratory, a test bed for new technologies in areas like life support and robotics, and a platform for astronomical and Earth observations. PMA 2 berthed on Node 1 serves as a primary docking port for the Space Shuttle. The U.S. Lab Module Destiny provides research and habitation accommodations. Node 2 is to the left; the truss is mounted atop the U.S. Lab; Node 1, Unity, is to the right; Node 3 and the Cupola are below and to the right. INTERNATIONAL SPACE STATION GUIDE ELEMENTS 23 ARCHITECTURE DESIGN EVOLUTION Architecture Design Evolution Why does the ISS look the way it does ? The design evolved over more than a decade. The modularity and size of the U.S., Japanese, and European elements were dictated by the use of the Space Shuttle as the primary launch vehicle and by the requirement to make system components maintainable and replaceable over a lifetime of many years. When the Russians joined the program in 1993, their architecture was based largely on the Mir and Salyut stations they had built earlier. Russian space vehicle design philosophy has always emphasized automated operation and remote control. The design of the interior of the U.S., European, and Japanese elements was dictated by four specific principles: modularity, maintainability, reconfigurability, and accessibility.

FOREWORD One of the objectives of the Air Force Center for Systems Engineering (AFCSE) is to develop case studies focusing on the application of systems engineering principles within various aerospace programs. The intent of these case studies is to examine a broad spectrum of program types and a variety of learning principles using the Friedman-Sage Framework to guide overall analysis. In addition to this case, the following studies are available at the AFCSE website. ■ Global Positioning System (space system) ■ Hubble Telescope (space system) ■ Theater Battle Management Core System (complex software development) ■ F-111 Fighter (joint program with significant involvement by the Office of the Secretary of Defense) ■ C-5 Cargo Airlifter (very large, complex aircraft) ■ A-10 Warthog (ground attack) ■ Global Hawk ■ KC-135 Simulator These cases support practitioners of systems engineering and are also used in the academic instruction in systems engineering within military service academies and at both civilian and military graduate schools. Each of the case studies comprises elements of success as well as examples of systems engineering decisions that, in hindsight, were not optimal. Both types of examples are useful for learning. Plans exist for future case studies focusing on various space systems, additional aircraft programs, munitions programs, joint service programs, logistics-led programs, science and technology/laboratory efforts, and a variety of commercial systems.

His true love was serving his country in the US Coast Guard, Merchant Marines, United Nations, US Army, and the NASA Space Programs as an aerospace engineer. As one of a handful of people to ever support the Mercury, Gemini, Apollo, Skylab, Space Shuttle, and International Space Station missions, Bob was an icon to his peers. He spent 44 years in this noble endeavor called manned space flight. In the memorial service for Bob, Milt Heflin provided the following insight: “Bob was about making things happen, no matter what his position or rank, in whatever the enterprise was at that time…it might have been dodging bullets and bombs while establishing communication systems for United Nations outposts in crazy places…it might have been while riding the Coastal Sentry Quebec Tracking ship in the Indian Ocean…watching over the Lunar Module electrical power system or the operation of the Apollo Telescope Mount…serving as a SPAN Manager in the MCC (where a lot of really good stories were told during crew sleep)…or even while serving as the Chairman of the Annual FOD Chili Cook-off or his beloved Chairmanship of the Apollo Flight
