Arctic Greenhouse May Lead to Farms on Mars CBC

Astronauts visiting Mars in the future may be able to look forward to a fresh salad when they arrive, thanks to Canadian research.
Lettuce, radishes and beets have been planted in a remote Arctic greenhouse, where researchers are learning how to grow crops without human contact in an environment that can’t normally support edible plants.
Alain Berinstain, the Canadian Space Agency scientist in charge of the project, said no other greenhouse is designed to operate autonomously like the Arthur Clarke Mars Greenhouse on Devon Island in Nunavut.
