"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. Cowing also talks about some of his own projects including the greenhouse he designed and built on Devon Island (and some serious hacks) near the North Pole. Currently, he's working in partnership with NASA Ames to restore a 1960's era Titan I ICBM & convert it for educational use."
