What started with a project at Cornell University in 2011 has skyrocketed, literally. NASA recently announced they were funding a $125,000 grant to build a prototype 3-D printer that could print pizza in space for future missions, possibly to Mars, where NASA says a 520-day food supply would be needed. The 3-D printer, they believe, could provide astronauts with food exceeding the 15-plus-year shelf life requirement.
