On the NASA/cows thing, the project is really part of a long-term terraforming idea that was designed to fulfill the new "smaller, cheaper, quicker missions" mandate. It's important to know a few things:
1. the "cows" are specifically bred/engineered for the task, using yak-hybrids. They're capable of withstanding the cold and on getting by with mot much water, and that all in the form of permafrost, but they're smaller, lighter and have slightly different digestive enzymes... so that...
2. The cows' digestive byproducts (yeah, farts, basically) have been shown to produce something like 100 gallons of breathable oxygen per day on a diet closely related to Martian flora (mostly arid lichens/mosses), and...
3. Once in place, the cows are pretty much self maintaining. No future trips to bring up supplies and whatnot -- just leave 'em there to create fertilizer and oxygen and provide a ready food source for future missions. Looking in the long term, it's the most economical option, actually. The main hurdle is getting the first cows to Mars safely and setting them down someplace where they've got the greatest chance of survival - plenty of tasty lichens and enough underground ice close enough to the surface for them to get to it. So once the data from the new Mars Odyssey probe gets collated, and matched up with the next batch of info from the Rover/Lander missions set to launch in 2004, it's the next logical step.
