So Sol 1291 was entry day, all 6 wheels inside Victoria.

JPL entry announcement

"Today, NASA's Mars Exploration Rover Opportunity entered Victoria Crater for the first time..... Opportunity drove far enough in -- about four meters (13 feet) -- to get all six wheels past the crater rim. Then it backed uphill for about three meters (10 feet). "

I will leave the final judgment of the winner to one of our adjudicators.

STP wins - his is the closest estimate.

I don't know if there will be additional prizes to the winner but this one is for sure.



Congrats Sattrackpro!

And I think centsworth II deserves another one too. smile.gif

A new topic would be when the Opportunity would be getting out of Victory. Indeed, now it is long time to predict on two things: She will stay there forever or will leave out of the Victory. smile.gif

Thanks, but I think Sattrackpro deserves the undisputed title.
(Ill take a snack size bar for second place.)

Were these first 'steps' not conducted as an ingress test, after which they should try to get completely out again?
Otherwise Victoria crater could become Oppy's grave huh.gif

Catch up Phil rolleyes.gif - they did a toe-dip in and out again - and since then, have now gone fully back in.

I am not sure that I really have my mind around this toe dip concept. They put all six wheels down the slope, then they backed up to ensure that they could get out. Why? If there was undue slippage or (unlikely but possible as Brian L implied) the backout resulted in a purgatory event, then what was the payoff for this evolution. Better to have deferred the risk until after exploration within the crater had been completed and then experiment with egress. But then again I guess that I am too conservative ever to be a rover driver.

Driving out they used the visidom technique to make sure they were not slipping too much - and if you read the updates you'll see that the rover identified a slip of 40% and stopped driving.

Better to know you can get out before getting in much deeper.

The toedip policiy makes sense as far as traction on the (hopefully) rocky interior slope goes. If that traction is anomalously bad, you probably want to rethink going in deep, and may want to get out and try somewhere else. But if the raised drift at the edge of the rim could not be driven back across without severe slippage, but the rocky slope was OK, then clearly once you're "in" you may as well go all the way in for the white layer. As it turned out there was some slippage backing out on the drift, but hopefully that won't effect the eventual egress.

It's all dust under the bridge now - we're in. Plus, egress worked and wasted little time. Hooray for our side!
