Red Mars could, one day, have roads made of yellow brick. Or orange-yellow bricks.
A team of researchers at Northwestern University has developed a kind of concrete for Mars that doesn’t require water. Instead, it combines Martian soil with liquid sulphur, obtained by heating the element up to 240 Fahrenheit until it melts into a lemon-yellow puddle.
The material would be twice as strong as Earthly concrete. Plus, it’d be highly recyclable because the blocks could be melted down and reset into a new form.
