Space cuisine has come a long way since the first astronauts went up in 1961 those Gemini astronauts primarily had gelatin-coated food cubes and aluminum tubes of apple sauce.
They now get fresh fruit on occasion as well as such choices as shrimp cocktail, mashed potatoes with bacon, green beans with garlic, and New Orleans jambalaya , they have to be especially careful with some food choices, though.
For example, the Russians often bring tomatoes when it is their turn to supply the space station it is not wise to bite right into a fresh tomato because it can squirt out juice which then has to be tracked down.
Getting the astronauts to Mars will take another six months, returning adds yet another six months, and delays have to be anticipated due to possible weather or mechanical problems.
