Our latest drill hole – Marimba – has a distinctly reddish colour. This probably means it has a lot of ferric oxide in it. This is the sort of mineral signature we are expecting as we get close to Hematite Ridge and suggest the chemistry of the ancient groundwaters and related minerals are changing as we progress up Mt. Sharp.
This blog is a record of my experiences and work during the Mars Science Laboratory mission, from the preparation, landing on August 5th 2012 Pacific Time, and onwards... I will also post updates about our other Mars work on meteorites, ExoMars and new missions. You can also follow the planetary science activities with @LeicsPlanets Professor John Bridges, School of Physics and Astronomy
