The US space agency, along with scientists from the University of Central Florida (UCF), is investigating the possibility of mining metal on the surface of Mars. NASA wants a way to see if it can get building materials in this way.
NASA is still working on a project to send people to Mars, but before this mission comes, many serious problems must be resolved beforehand. The biggest issue is the building materials needed to build habitats for astronauts. They can not be delivered from Earth, because it would be too expensive, so you have to look for them on the spot.
We have already heard of plans to build an ice habitat, but this material is only suitable for small structures and larger buildings need something more solid like metal. NASA, together with specialists from the University of Central Florida, is investigating whether the metal could be used on Mars to be used as a construction material, as well as as a 3D printer material to create the necessary components.
