NPR: 50 Years After Apollo 11, Here's What (And How) Astronauts Are Eating.
That reminds me: don't think I've ever actually tasted Tang, nor have I ever really felt the need drink that stuff.
Over the years though, I've generally come to the conclusion that astronauts don't get the gift of good food. I'd like to think that life for the ISS crew sucks less than shuttle and Apollo crews suffered in terms of food stuffs but I'm pretty sure the day when space food is really great food rather than just the best we can do, is still quite far off.
The 20th century kind of brought a lot of advancements to storing, packing, and preserving food. But some problems remain unsolved, lol.
