This month, about 50 feet (15 meters) under a Swiss glacier, you can experience what it might be like to live on the moon. Space agencies like NASA are looking to the moon as a waystation to venture beyond, to Mars and other cosmic destinations. One of the most viable spots for a lunar base could be inside a crater on the south pole of the moon, where scientists have confirmed the existence of water ice, a crucial resource for astronauts. To offer an idea at what such a habitat might look like, European researchers and students are conducting a mock moon habitat trial under a glacier near the famous Matterhorn in Switzerland's Alps. Called IGLUNA, the demonstration is organized by the Swiss Space Center and the European Space Agency.
