“Space is no place for a helpful hardware store. So an astronaut is in a pretty tight spot when the doohickey on the manifold breaks and the nearest replacement is 220 miles away-straight down. Roger Spielman thinks he has an answer. Spielman is quite literally a rocket scientist for Boeing Canoga Park-formerly Rocketdyne-and he and his brethren are on the brink of a solution so simple you’d expect to find it in a cartoon. Fax it. That’s right, fax the part, then print it. Send a 3D computer-assisted design file to the International Space Station, where Interplanet Janet feeds the data into a machine that assembles the part from a bucket of powder in about a half-hour.”
