Here are a couple of those tidbits:
Since CRISM detected the hydrated sulfate at Santa Maria, the CRISM team has homed in on Victoria Crater and detected the same signature where the rover had been and found hydrated sulfate. "We've never seen this signature before over Victoria with CRISM, because we never had an oversampled observation where we were taking 6 meter samples alongtrack with 18 meter pixels. So now we've detecting this signature in two places we've been," Arvidson confirmed.
So this says that there actually isn't
something unique about Santa Maria, at least as far as the CRISM signature goes.
And nothing too surprising about the upcoming plans:
From Ruiz Garcia, the plans calls for Opportunity to drive another 20 to 30 meters further to the northeast to a chosen waypoint, where it will take some final stereo images of the interior of the crater. The scientists hope to combine all the stereo images the rover took here and create a 3-D map of Santa Maria. "Then we'll start heading for the hills," said Arvidson.
