Red Rocks in Endurance
Interesting article here.
Opportunity, meanwhile, has descended about 30 feet into the small Endurance Crater in Meridiani Planum and is encountering unusual rocks as well.
Meridiani Planum is littered with large numbers of small, round rocks that the team has called blueberries.
But now the craft has encountered some similar stones that are also round, but are lighter and redder. The stones are very coarse and rough, unlike the smoother blueberries, and are more irregular in shape. Some appear to have blueberries inside them.
