Technologies are being evaluated by National Aeronautics and Space Administration (NASA)'s Advanced Food Technology element. A transportation cost measure known as equivalent system mass (ESM) is being implemented at NASA as a preliminary assessment strategy for technologies. This study concentrated on calculating ESM values for 3 commercial bread‐maker technologies and aprototype bread‐maker technology currently unavailable in the marketplace. Information regarding weight, volume, power consumption, cooling, and crewtime were collected. One commercial technology produced a lower ESM value and performed better in most evaluative categories. However, non‐ESM factors may contribute greater roles in technology selection. In this, the current ESM equation may not be capable of capturing all relevant aspects of a food technology. bread
