The International Space Station is set to launch a baking experiment in 2018 in which they'll use specially-devised dough with a microgravity oven to create a palatable, but crumb-free bread.
New Scientist reports the "Bake in Space" mission seeks to meet the needs and desires of future astronauts and space visitors by letting them "bake where nobody baked before." The scientists will try to create "typical" weekend German bread rolls using the low-energy convection oven.
Because of the microgravity environment, tiny particles, such as breadcrumbs, can be a problem if they get into electrical systems and ventilation filters.
Astronauts used to pre-cut their bread into bite-size cubes and coat each with gelatin to keep crumbs at bay.
