Nasa's Curiosity rover has found soil on Mars to be similar to Hawaii's after sifting and scanning its first sample on the Red Planet.
As had been theorised, much of the sample is made of weathered "basaltic" materials of volcanic origin, like that seen on the islands of Hawaii.
The sample seems to contain dust carried from afar by Mars' global-scale storms, as well as coarser sand of more local provenance.
