| Abstract (English): |
The food that NASA's early astronauts ate in space is a testament of their strength. John Glenn, America's first man to eat anything in the near-weightless environment of the Earth's orbit, found the task extremely hard and the menu to be quite limited. Other Mercury astronauts had to base their nutrition on bite-sized cubes, freeze-dried powders and semi-liquids packaged in aluminum tubes. Most of them agreed that the foods were unappetizing and disliked squeezing the tubes. Moreover, freeze-dried foods were hard to rehydrate and the crumbs got stuck on the walls of the spacecraft. Ever since, multiple technologies and studies on the energy requirements of astronauts and food preservation have been developed. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): |
La alimentación de los primeros astronautas de la NASA es un testimonio de su fortaleza. John Glenn fue el primer hombre de Norte América que comió en un estado de microgravedad, lo cual no fue nada fácil, además de contar con un menú limitado. Él, al igual que los astronautas de la expedición Mercury tuvieron que basar su alimentación en cubos del tamaño de un bocado, polvos liofilizados y dietas semilíquidas envasadas en tubos de aluminio. La mayoría de los alimentos eran poco apetecibles, los alimentos liofilizados eran difíciles de rehidratar y los polvos en la microgravedad quedaban pegados por las paredes de la nave; desde entonces se han desarrollado múltiples tecnologías y estudios sobre los requerimientos calóricos de los astronautas y conservación de los alimentos.
