Future Mars explorers might build structures on site by tapping into their own blood

By casting one eye to a past where ancient buildings were held together with animal blood, and one eye to a future where humans use Martian soil for on-site construction, scientists have cooked up a new recipe for cost effective "cosmic concrete." Groups of astronauts in space could produce hundreds of kilograms of the material each year, according to the scientists, continually expanding a potential Martian habitat with every visit.
