Now, for the first time, researchers have successfully determined the age of a Martian rock—with experiments performed on Mars. The work, led by geochemist Ken Farley of the California Institute of Technology Caltechcould not only help in understanding the geologic history of Mars but also aid in the search for evidence of ancient life on the planet. However, shortly before the rover left Earth in 2011, NASA's participating scientist program asked researchers from all over the world to submit new ideas for experiments that could be performed with the MSL's already-designed instruments.

Rubidium-strontium dating This is based on the decay of rubidium isotopes to strontium isotopes, and can be used to date rocks or to relate organisms to the rocks on which they formed. It suffers from the problem that rubidium and strontium are very mobile and may easily enter rocks at a much later date to that of formation. One problem is that potassium is also highly mobile and may move into older rocks.
