ISRO plans to build 'igloos' on Moon for astronauts
The Indian Space Research Organisation (ISRO) has started working towards developing 'igloos' on Moon, called the lunar habitats, for safe keeping of astronauts. The habitats will be built by sending robots and 3D printers to the Moon and using lunar soil. Although no mission plan has been prepared yet, scientists want to have the technology ready for building these structures.
