Eating bread in space is a surprisingly dangerous undertaking: the free-floating crumbs could cause someone to choke, lodge themselves in someone's eye, or worst of all, cause a fire if it gets into the electrical panel. That's why most astronauts have to eat the less appealing alternative -- the tortilla.
Bake in Space wants to give astronauts freshly baked, crumble-free bread in space by creating an oven that can bake bread in space. The creators anticipate being able to do this by 2018, but there are a few challenges, like avoiding giant hot air bubbles from the oven and having to create an oven that uses one-tenth of the power that a typical oven on Earth would use.
