British scientists developed a method that could potentially solve the problem of housing on Mars and transporting building materials to the Red Planet.
They proposed to create a concrete-like material using space dust and human blood together with the sweat and urine of astronauts to build shelters for future colonies.
Transporting one brick to Mars can cost nearly $2 million, making the colonization of the Red Planet extremely costly. Therefore, scientists proposed using materials that can be found right on the planet for construction, as well as the astronauts themselves.
The combination of human blood plasma protein and cosmic dust creates a concrete-like material (called AstroCrete) that is about as strong as the earth concrete and can be used for construction.
Additionally, scientists have discovered that adding urea (the body excretes this biological waste through sweat, urine, and tears) to the AstroCrete increases the strength of this building material, making it even stronger than regular concrete.
British scientists have calculated that a crew of six can produce more than 500 kilos of AstroCrete during a two-year mission to Mars.
