Feeding Martians

An interesting project at the South Pole, involving agriculture in a controlled (and in this case, sunless and soil-less) environment: To the moon…South Pole greenhouse model for growing freshies on other worlds

Crops of lettuce, kale, cucumber, peppers, herbs, tomatoes, cantaloupes and edible flowers comprise many of the plants grown in the climate-controlled chamber. Because the importation of soil is restricted by the Antarctic Treaty External U.S. government site, dirt is not used to grow the plants. In fact, the closest local dirt is nearly two miles beneath the ice on which the station sits. The plants are grown in a hydroponic nutrient solution instead — no dirt needed.

For that matter, no sunlight is needed either. The growth chamber, which was built in the winter of 2004, makes its own light via 13 water-cooled, high-pressure sodium lamps. In this bright environment, it is not uncommon to find people, like the plants, dwelling happily under the intense light produced in the chamber during the dark polar winter.

Carl and I put a lot of thought into extraterrestrial agriculture while writing In the Shadow of Ares, not least because the primary setting for the book is a very large agricultural settlement. Interestingly (or perhaps not surprisingly), we came to some of the same conclusions as these researchers. Of particular note, the morale benefit to settlers in an inescapably indoor environment of having an open green space (or Greenspace, if you’ve read the book).

Teaching Citizen Journalism

Spending the morning at Independence Institute with a group of bloggers and pro-liberty activists from Kyrgyzstan, sharing People’s Press Collective’s citizen journalism experience.

A really interesting collection of bloggers, including the director of the only free-market think-tank in Central Asia.
