MRE stands for Meals Ready to Eat and that is exactly what they are: meals that can be eaten at room temperature as soon as they are opened. They a prepared and packaged for long term compact storage and thus have as much calories as can sustain a person on 3 meals a day.
Astronaut meals are more like freeze dried camping meals - they are intended to be reconstituted with hot or cold water, in the package rather than in a pot as camping meals are and consumed in a zero gravity environment so they either stick together or are contained (soup, juice, etc.) Great attention is paid to reducing the output from meals (gas, urine, bowel)..

With every day pass, our country is getting into more and more trouble. The inflation, unemployment and falling value of dollar are the main concern for our Government but authorities are just sleeping, they don’t want to face the fact. Media is also involve in it, they are force to stop showing the real economic situation to the people. I start getting more concern about my future as well as my family after watching the response of our Government for the people that affected by hurricane Katrina.
According to recent studies made by World Bank, the coming crisis will be far worse than initially predicted. So if you're already preparing for the crisis (or haven't started yet) make sure you watch this video at http://www.familysurvival.tv and discover the 4 BIG issues you'll have to deal with when the crisis hits, and how to solve them fast (before the disaster strikes your town!) without spending $1,000s on overrated items and useless survival books.

I'm an ex-marine and a decorated war-prisoner, I fought in 7 wars for more than 20 years. Let me congratulate you for your work. This is the best survival guide I read so far. It's exactly what a normal person should know and can learn easily to get himself and maybe others out of a life and death situation https://tr.im/yIKXy

I'm not really sure about the military MRE's but I remember reading somewhere about freeze drying ice cream for astronauts.
