• The discovery of volcanic tunnels on the moon could provide a natural shelter for the first lunar colony, cosmonauts and scientists said on Tuesday.
• "If it turns out that the moon has a number of caves that can provide some protection from radiation and meteor showers, it could be an even more interesting destination than previously thought," he said. 
• "In ESA, there is still a very strong focus on the moon. It could be a natural first to go there,"
