American university selling Martian dirt for $20 per kg
The University of Central Florida (UCF) in the US is selling Martian dirt for $20 per kilogram plus shipping. A team of UCF astrophysicists has developed a scientifically based, standardised method for creating Martian and asteroid soil known as 'simulants'. Its formula is based on the chemical signature of the soils on Mars collected by NASA's Curiosity rover.
