Features

  • WORF is available for scientific and commercial payloads.
  • WORF is also a resource for public outreach and educational opportunities for Earth Sciences (e.g., the EarthKAM, ISERV, etc.). The resulting images can be used to study global climates, land and sea formations, and map routes for city planners. Special sensors can also provide important data - for example, atmospheric conditions or properties as well as data for new sensor technology development.
  • WORF provides a facility which allows both remotely operated payloads and crew members to perform Earth/space science research, including hand held photography, at  the US Lab Science Window.
  • WORF is based on an International Standard Payload Rack (ISPR) and utilizes avionics and hardware adapted from the EXPRESS Rack program.
  • The rack provides a payload volume equivalent to 0.8 m3, and will be able to support up to 3 internal payloads simultaneously, depending on available resources and space available at the window.
  • WORF also provides access and equipment for crew-Earth observations, such as crew restraints, 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 homogeneous, 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.
