International Space Station U.S. Laboratory Outfitting, Part 2 961342

This paper describes the current USL outfitting with design and development changes incorporated during the past year.
The International Space Station (ISS) USL is outfitted with eleven systems racks, an optical quality nadir window for earth viewing experiments and accommodations for thirteen International Standard Payload Racks (ISPRs). International payloads utilize this outfitting in a “shirt sleeve” environment by sharing allocated system resources and flight crew time to perform long term microgravity experiments. Recent changes in Command and Data Handling, 120 Vdc power, liquid and air cooling, audio and video communication, space vacuum and microgravity systems resources are included.
User interfaces, systems performance and environmental conditions, in addition to the ISS USL outfitting configuration, are also updated in this ICES paper.
