We are continuing the Bagnold Dunes campaign, with  stops 3 and 4. This NavCam view shows the Curiosity robotic arm for the team's examination.  Here we have checked the position of the MAHLI cover (seen at the bottom of the robotic arm turret) and all is as planned for future operations.

We have been examining Ireson Hill and found this unusual 10-15 cm diameter rock- called Passagassawakakeag !

The shape is an almost perfect Dreikanter.  That's a German word  for a sample in desert or periglacial environments formed by the abrasion of blown sand. Dreikanters typically have a pyramid shape with flat wind-abraded facets.

We have started the second part of the Bagnold Dunes campaign. This NavCam image shows Bagnold dunes in front of Ireson Hill. This first in the current dunes campaign is Called Mapleton.

Good news for the MSL team is that ChemCam is back in operation after having an electrical fault. We have started with a 5 x 1 laser raster on the ripple crests.

We have found another (the 4th) meteorite.  The fist sized sample called Ames_Knob - which was analysed by ChemCam - turns out to be composed of Fe and Ni metal. This iron meteorite looks like it fragmented in the martian atmosphere, producing fragments like Ames_Knob and Egg_Rock, Lebanon and Littleton. It is notably fresh and unaltered so may have fallen relative recently, within the last thousands of years perhaps.
