While a lot of attention has been paid the last few days to the odd rock which “appeared” beside the Opportunity rover, the other rover, Curiosity, has found its own interesting little chunk of a Martian puzzle. While not as publicized, it has been the subject of a lot of discussion among mission followers. What are the ribbon-like bands? Could they be feldspar laths? Another type of lath? Something else entirely? Curiosity has taken Mastcam and ChemCam images, but no other information is available yet.

  1. Don’t expect much actual information. Lots of pretty pictures but if its facts you seek you’ll need to fork out $$. Even though we “paid for this microphone”.
