NASA engineer Ed Smylie, who helped keep the Apollo 13 astronauts alive using a combination of a spacesuit hose, sock, plastic bag, cue cards and duct tape, has died at age 95. Four hours after the explosion that tore through Apollo 13 in 1970, Smylie became concerned that the crew would suffocate due to the accumulation of carbon dioxide in the air. He and his team of 60 came up with a plan, tested it and explained to Jim Lovell, Fred Haise and Jack Swigert how to build it during their emergency trip back to Earth. Smylie, who died in late April, received a Presidential Medal of Freedom for his service to the space program. Here's more from @Spacecom.
