As Mars Pays a Visit, NASA
Wonders What to Eat Up There

The Red Planet is upon us this week, as it’s closest to Earth in its 2-year orbit. While backyard astronomers or simply stargazers go into their usual frenzy of Internet commentary and great photos, astrophysicists continue researching ways for our first visit to a planet other than our own. It won’t be easy.
Practical considerations such as what to wear and how to live up there assume epic proportions, as do issues of safety and comfort. Nothing is as hard, though, as to figure out what astronauts will eat during the trip, and specially, once they’re there. NASA, for example, started a four-month program to develop a healthy diet fit for astronauts.
Open to anyone, the program will also address the fact that space travelers seem to crave spicy foods and sweet and sour things. The technology of growing and recycle food in space will have to be greatly improved too if we’re to survive in such inhospitable conditions.
These are but a few of the so far insurmountable obstacles that the estimated three-year trip presents to earthlings. We still don’t even have a suitable rocket to take us there, nor the sources of renewable fuel are sufficiently up to par to supply us with the energy necessary for the journey. And never mind getting into the psychological challenges such a gruesome enterprise would represent.
So, while this is not even Mars’s closest approach to Earth, being at a mere 63 million miles from us, it’s still fun to gaze at its fuzzy surface where the rovers Spirit and Opportunity wander about and the Phoenix lander now sits silently, and at the Gale Crater where the Curiosity Continue reading
