Astronauts on the first space missions used frozen and dried foods. Their space capsules used fuel cells to generate electricity. Water, a byproduct of fuel cells that combine oxygen and hydrogen to produce electricity, was abundantly available on those spacecraft; so astronauts could mix hot water with dried food at mealtimes to create a less than appetizing meal. These foods were not very popular with astronauts, and they grew disgusted with the taste and appearance of these foods after a few days.

Live for ourselves not for showing that to others.

So basically early space travel was like a free ticket to the worst diner in the galaxy btw the movie was super nice
