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.
According to NPR, German engineer Sebastian Marcu and one of his fellow engineer friends started Bake in Space to solve the problem of bland space tortillas. 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.
