QUOTE (Shaka @ Nov 28 2006, 03:08 AM)  We could call these two schools of thought, the "Clean Streakers" and the "Dirty Streakers"! Some fence-sitting by Steve Squyres...  ""It could be dark sand that has been blown out of the crater," Squyres suggested. "Alternatively, it could be places where there has been selective stripping of fine-grained dust by locally enhanced winds," he pointed out. The MER team is planning a campaign to study one of these streaks, he said, once Opportunity gets over to that area." -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

QUOTE (ustrax @ Mar 1 2007, 08:58 AM) ""It could be dark sand that has been blown out of the crater," Squyres suggested. I think the presence of El Dorado (Ultrea)-like dark ripples below the crater rim where the dark steaks occur argues for the dark sand hypothesis. |

While I'm still in the clean-sweep camp. The dark sand within Victoria isn't, to my eye, as dark as the streaked surface.

QUOTE (Shaka @ Nov 25 2006, 11:58 PM) Wow! If I live to be a hundred, I'll never understand why we've sailed right on past the Beacon toward "Boat Ramp". Maybe Opportunity will visit the Beacon on the way back to Duck Bay? Nov 25, 2006... wow. |
