What do astronauts EAT in space? Well, sometimes PIZZA. And chocolate cake! But also... liquid salt?
Most of the food on the International Space Station is either heat processed and ready to eat Or freeze-dried and just needs water. The lack of gravity makes assembling and eating food a bit harder…
It also means there’s certain foods they simply can’t bring! Any loose crumbs could float into equipment and damage it, so salt and pepper come in liquid form, and to avoid bread crumbs, they eat a lot of tortillas! Zero gravity also makes food behave weirdly...
As more people go to space, and for longer, we’ll need to find ways to effectively grow enough food with limited resources.
