Why is spirulina powder preferred over fresh produce for long-duration space missions?
Answer
It is shelf-stable, light, and nutrient-dense
Logistical constraints on spacecraft are severe, with every gram of weight costing significant capital. Fresh produce is heavy, perishable, and requires significant storage space. Spirulina powder, by contrast, is light and shelf-stable, meaning it does not spoil quickly and takes up minimal space. This efficiency makes it an ideal candidate for packing into the strict cargo limits of a spacecraft, ensuring crews have access to nutrition throughout their mission.
