As reported on NPT, researchers from the University of Hawaii and Cornell University want you to send them long-lasting recipes. They want to help NASA determine an extremely durable menu to keep astronauts fed on long space journeys, Mars in particular.
Other people interested in how future astronauts dine include PETA. The group has renewed their appeal for all future astronauts and any Martian colonists to be vegan only.
I, myself, am an omnivore with a particular penchant for steak. However, the people at PETA may have a valid position. Animal protein is excessively dense compared to vegetable matter. Animal protein is also far more costly to produce than vegetables. Also, vegetables will produce oxygen while animals would consume oxygen. The transportation costs of lifting denser material into space for an approximate four month journey could be prohibitive.
With limited resources and support from Earth, it would seem that a vegan diet may be in store for the first visitors to Mars. Also, no one really knows how Earth animals would react to any Martian colony. The gravity is lower, the Sun dimmer and the magnetic poles are weaker. It may not be possible to bred Earth based animals on mars.
With all this, you have to keep in mind that regular Martian excursions are in the future. However, I don’t think that everyone will be happy sipping their dinners for months on end. The food tests at the various space stations that we humans have launched show that everyone loves a “care” package from home now and again.
