According to scientists and experts at NASA's Langley Research Center, we could be one step closer to colonizing mars with their new 'The Mars Ice Home'.
The inflatable tube is lined with a shell of water ice, using materials found on Mars - with the water protecting the inhabitants from cosmic rays, and could even be repurposed as rocket fuel for the Mars Ascent Lander.
Right now, NASA's impressive Mars Ice Home is a concept with some issues, as experts have said it would take around 400 days to fill the shell with enough water from Mars. Robots could help, inflating and pumping the shelter while the human astronauts are on their journey from Earth to Mars. The Ice Home will continue to evolve, but this is an exciting new step.
