Here you go. Just put quotes around parts I thought were interesting. What it tells them - there was water on mars and is or was life on mars now
"From the ongoing stream of data coming down, the dark red stuff appears to be "iron manganese oxide of some kind," while the surrounding white
part "represents some kind of sulfate," Arvidson suggested at month's end. "These are all minerals and elements soluble in water." It could be
Pinnacle Island is "an ancient water-laid deposit" from the Noachian Period some 4 billion years ago, "or it could be from a more recent period,"
""We're completely confused and having a wonderful time," summed up Squyres."
"In brief, the MER science team, led by Arvidson, the first author of the paper, concluded that billions of years ago, an ancient wet environment
that was milder, warmer, wetter, and older than any the rover had previously found could have offered a habitat for life to emerge. The MER
researchers based their conclusions on the evidence of clay minerals, in the form of iron-rich smectite and a more aluminous smectite that Opportunity
ground-truthed at Matijevic Hill, and believe the wet conditions that produced these smectites preceded the formation of the Endeavor Crater about 4
billion years ago."
"Additionally, the MER scientists found evidence for more aluminous smectites in the fractures of what are known now as Matijevic Formation rocks.
"Compositional data for fractures in the layered rocks suggest formation of aluminum-rich smectites by aqueous leaching," they wrote. "Evidence is
thus preserved for water-rock interactions before and after the impact, with aqueous environments of slightly acidic to circum-neutral pH that would
have been more favorable for prebiotic chemistry and microorganisms than those recorded by younger sulfate-rich rocks at Meridiani Planum.""
"Once the rover finishes the examination of Pinnacle Island, the plan calls for it to back up and take a look at the possible places from where
Pinnacle Island and the other little stones popped out to fall into Opportunity's view – its solar arrays have been blocking the suspected part of
the hill from view. Then, with the best winter power levels this rover has had in three Martian winters, averaging just above 350 watt-hours more than
1/3 of its full capability, Opportunity will move on to another exposed outcrop in Cook Haven, just 3 meters away. Called Green Island, this outcrop
also hints of clay minerals."
