A new space experiment is taking the baking tip “let your bread rise” to the extreme.
Slated to launch to the International Space Station in 2018, “Bake in Space” will test a specially-devised dough with a microgravity oven to bake bread in orbit for the first time in history.
“Baking where nobody baked before,” the team behind the Bake in Space experiment quipped. “Bake in Space seeks to address the scientific and technical challenges relating to the production of fresh bread in space.” [Space Food Evolution: How Astronaut Chow Has Changed (Photos)]
Led by group of German scientists, engineers and science communicators, including former shuttle astronaut Gerhard Thiele, Bake in Space is not just about adding to the space station crew's menu, but meeting the needs and desires of future astronauts as spaceflight opens to more people.
“As space tourism takes off and people spend more time in space, we need to allow bread to be made from scratch,” Sebastian Marcu, CEO and founder of Bake in Space, told New Scientist.
Breadcrumbs through space history
The Bake in Space experiment will try to produce “typical” weekend German bread rolls using a compact, low-energy convection (or possibly vacuum) oven and a special dough that produces a palatable, but crumb-free bread.
Breadcrumbs in space can be a reason for concern. Given the microgravity environment, the tiny particles can cause problems if they get into electrical systems and ventilation filters. They can also pose a health risk if inhaled.
NASA's early solution — after Mercury and Gemini crews smuggled deli sandwiches to space — was to pre-cut their bread into bite-size cubes and coat each in gelatin to keep any crumbs contained. Later, during the space shuttle era and continuing to today on the space station, tortillas took the place of loaves as the bread-product of choice.
