Although the potassium-argon method has been used to date rocks on Earth for many decades, these types of measurements require sophisticated lab equipment that could not easily be transported and used on another planet.

Farley had the idea of performing the experiment on Mars using the SAM instrument.

Farley and his colleagues determined the age of the mudstone to be about 3.86 to 4.56 billion years old.

Increasingly, the other techniques are used, such that probably no one technique dominates for meteorite dating.

Rb-Sr is a good example for explaining the process, however.

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. Findings from the first such experiment on the Red Planet—published by Farley and coworkers this week in a collection of Curiosity papers in the journal —provide the first age determinations performed on another planet.

The paper is one of six appearing in the journal that reports results from the analysis of data and observations obtained during Curiosity's exploration at Yellowknife Bay—an expanse of bare bedrock in Gale Crater about 500 meters from the rover's landing site.
