Mars Terraforming is Not Possible Using Currently Available Technology, Researchers Say 0

On Mars, the atmospheric pressure is around 0.6% of Earth’s. Any liquid water on the surface would very quickly evaporate or freeze. One of the challenges of terraforming the Red Planet is to increase its atmospheric pressure. The Martian polar caps, minerals, and soil could all provide sources of carbon dioxide and water to thicken the atmosphere. But a new study in the journal Nature Astronomy finds that processing all sources available on the planet would only increase the pressure to about 7% that of Earth, far short of what is needed.

- August 1, 2018
Future missions to Mars and beyond will require innovative options to shelter explorers. NASA’s 3D-Printed Habitat Challenge, a Centennial Challenges competition, seeks ways to create or develop the technologies needed to create such habitats on-site, and challenges citizen inventors to lead the way. Now a panel of experts from NASA, academia and industry has selected the top five teams to share a $100,000 prize in the Phase 3: Level 1 of the competition.
