Allende Opportunity woke up to May at the pitted rock Allende, named after the stop on El Camino Real de Tierra Adentro, the mission’s current naming theme. Although science team members had been referring to thee rocks as vesicular, they are now simply calling them pitted. “Vesicular rocks are characterized by vesicles that form when magma or lava degasses and leaves holes,” explained Deputy MER Principal Investigator. “But now the science team is beginning to think that maybe the pits are caused by some kind of chemical corrosion.” NASA / JPL-Caltech / Cornell / ASU
