Re: “Tomatoes on the Moon”

"Similarly, water for the plants would be extracted from astronaut urine,"

Plants could well help with the recycling of water, CO2 and other materials. But the plants wouldn't need to rely on recycled water at a polar base.

Chandrayaan 1's Mini Sar radar has found what seem to be sheets of relatively pure water ice at least two meters thick. http://www.nasa.gov/mission_pages/Mini-RF/…

The ice could be used to supplement the CELSS the astronauts rely on.
