Window Observational Research Facility

The Window Observational Research Facility (WORF) is an Earth science remote sensing facility that uses the nadir (Earth-facing) Destiny science window in the U.S. Laboratory Module. WORF was developed by Boeing and is managed by NASA’s MSFC. WORF is operated by the Payload Operations Integration Center at MSFC. The Destiny window has the highest-quality optical properties ever flown on a human-occupied spacecraft. It also allows crew members to perform Earth and space science research, including handheld photography. WORF can support up to three investigations, depending on the resources needed. WORF uses existing EXpedite the PRocessing of Experiments to Space Station (EXPRESS) Rack hardware for power and data. Payloads can be directly controlled by the ISSInternational Space Station crew or remotely controlled from the ground. WORF provides multiple attachment points (payload support shelf, seat tracks) for multi-sensor configuration flexibility. Nadir view is optimized, but view angles up to ~25° introduce little optical error. Destiny window is most transmissive in the visible/near infrared wavelengths. An external, ground-commanded shutter allows for 24/7 operations (within flight rules constraints). Shrouds and curtains are available to create a light-tight environment within the WORF. WORF provisions include onboard interfacing cables/hoses, a laptop, electrical connectors/fluid QDs. Payloads that have used WORF have focused on geology, agriculture, ranching, environmental and coastal changes, natural disaster assessments, meteor showers, and education.
