Astronaut blood can be used to make concrete on Mars, scientists say
Human colonies on Mars can — and probably should — be built using the actual blood, sweat and tears of the astronauts who build them.
That’s according to scientists at the University of Manchester, who say they’ve come up with a bloody brilliant way to solve the expensive challenge of sending building materials to Mars.
Water is scarce on Mars and it costs $2 million to send a single brick to the Red Planet, according to estimates. But astronauts can simply make their own concrete on-site using Martian dust and their own blood, according to findings published this month in the journal Materials Today Bio.
And it’s not a theoretical thing. According to the study, scientists have already made a concrete-like substance called “AstroCrete” using human blood and synthetic regolith, …
