“Keith Cowing talks about the kind of hacks made famous by the Apollo 13 mission, instances where the crew had to improvise using materials at hand. He discusses the following: Skylab Rescue – the umbrella used to replace solar insulation and boating tools bought at a local marina; Syncom Rescue – tools made out of plastic and duct tape; Apollo 13 CO2 removal, use of LEM engine, etc.; Apollo lunar rover fender repair; STS-120 EVA solar panel repair, and ISS camera tracker made from a power tool.”
