Now when the article said they plan on moving "forward" do they me relative to the vehicle's orientation or relative to the vehicle's prior motion?

At this stage, I'll support anything, as long as it's out!

QUOTE (SteveM @ Aug 5 2009, 03:22 AM)  Your suggestion that there's dust up there could explain the depressions; it's certainly more plausible than denting.  It's out of focus, remember, and over the last 5 years, you can see the dust arriving, getting blown away etc. With the recent cleaning events and the strong winds inferred - clumping and moving of dust is to be expected. It's well worth hunting for normal pancam images of it to get a better idea. |

QUOTE (maycm @ Aug 5 2009, 12:21 PM) New Scientist the moves to eventually free Spirit Thanks for the link. I thought the punch line was at the end of the article - ------- "It's going to take us a long time to get out," Callas told New Scientist. "But it's encouraging that the rover in the sandbox is climbing; it has enough capability to fight Earth gravity to get altitude. (my insert: e.g. climb uphill away from the 'sand' trap) We're expecting that on Mars, where there's only three-eighths gravity, that the rover may actually do better." Better - that's good news. |

Rover insiders say that if all goes well, there could be some movement attempted after the weekend.
Fingers crossed! Good luck Spirit

The preceding statements give some context. "The region we were safely over before could be a challenge now," Callas says. "It's like skating on thin ice." So instead of backing up, scientists plan to tell Spirit to push forward. I interpret that to mean they will be continuing in the direction of Von Braun and Goddard. |

So in the best case scenario were stuck between a sand trap and uncharted territory. This should be interesting.

 Edit: Scratch that, if we could determine that we would never have gotten in this scenario in the first place. |

These rovers were designed to explore uncharted territory. QUOTE (briv1016 @ Aug 5 2009, 04:31 PM) Now that we have fallen into it, I think we can see it's boundaries. It doesn't appear to be very far to the other side of the pool. -------------------- ...Tom (thinks he should use more emoticons)

At this point I will be very happy if Spirit is able to dog-paddle to the shallow end.

Frankly I'm quite confident that it's a matter of when, not if. TeeBee has apparently demonstrated progress, and the real discovery was that there wasn't a simple pick-a-single-vector/translation maneuver solution.
It's a safe bet as well that Paolo, Sharon & the team now understand the MER's motive capabilities & characteristics far better than ever, and that's knowledge that will pay off big time for a LONG time even after Spirit is freed. My only concern at this point is that somebody besides them gets stuck with dismantling the sandbox after it's over; they all need a few beers & a few days off!
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
