How Shuttle Spacewalks Shaped Station Design

STS-37’s GRO repair used foot restraints and force monitoring; deliberate positioning protected astronauts and payloads during orbital-replacement-unit handling.

STS-37’s GRO repair required 60 pounds one-handed, while darkness obscured handholds; better dog-bone rails reduced force demands for future maintenance.

STS-37 warned Space Station Freedom work sites could reach minus 84°C; thermal-vacuum testing validated gloves, tools, tethers, and procedures.

After a five-year U.S. spacewalk gap, STS-37 found EVA expertise eroded; regular flight-testing was essential before station assembly.
