Oppy went right back up the same route today, just slightly off-center from the tracks that had started to dig in.
http://qt.exploratorium.edu/mars/opportuni...FYP1254L0M1.JPG One would like to know how much of this is part of a plan versus flip-flopping decisions each day. Are they packing down the dirt to facilitate crossing the dune? Did they simply decide that the rover was in no real danger and loosen up her drive parameters and send her back the same way? |

At least Mars is close to Earth, transmission rates are bumped up for more/faster data downloads, and they are not in the drive-every-other-day situation at the moment. Allows for quick analysis and recovery from hiccups. The rover stopped (almost certainly due to a detected slip condition), they ordered it to back up, looked at the situation, then went right back at the drift - all in 4 Sols, it appears.

QUOTE (Burmese @ Oct 10 2005, 12:41 PM) At least Mars is close to Earth, transmission rates are bumped up for more/faster data downloads, But a UHF pass is a UHF pass. Proximity to earth doesnt really make a difference for Rover Comms. It means Odyssey can downlink a UHF pass quicker to Earth, but for the rovers, that doesnt matter. Doug |
