This eGullet Q&A with a NASA food scientist is great–even though she has no sense of humor (note how she just doesn’t dish on in-flight food poisoning like you wish she would). Tortillas are the space-age bread, freeze-dried shrimp cocktail is very popular, but (gasp!) astronaut ice-cream was a one-time deal for the Apollo mission only. I’d get huffy and nostalgic about this, but really, that stuff sucked.
