From Mars Hill To Mars

In 2007 Advanced Superabrasives was approached to develop diamond wheels for grinding operations in outer space. (Click to see how we got there)

The first project was to verify operation of current Mars wheels used on the Spirit and Opportunity rovers. The grinding wheels are located on an arm of the rover called the RAT or “Rock Abrasion Tool”. The RAT, which has a mass of 687g; grinds an area of 45mm in diameter and 5mm in depth. It grinds these Martian rocks in search of any signs of life or water.

Advanced Superabrasives has also manufactured the grinding wheels in use on the Curiosity rover which just recently landed on the Martian surface. In addition to these achievements we are still working with NASA on other future planetary projects.
