Baking the first bread in space

Abstract

This Getaway Special program is a joint venture between Spar, Monarch flour and Telesat, with Telesat being responsible for the design, manufacture and implementation of the equipment. The purpose of the experiment is to investigate the behavior of bread yeast in the absence of gravity and in the presence of normal atmospheric pressure. The proposed design mixes flour, water and yeast on-orbit, allows the mixture to prove and then bakes it. This paper outlines the development history of the experiment, the various test programs and some of the problems encountered, with their solutions.
