"Expect news stories shortly after, everywhere. :-) "
If it wasn't for the smiley at the end, that statement would make me very nervous. |

It's a reasonable expectation that you will see headlines about NASA trying to rescue a "$300M rover" that has been "stuck for six months."
NASA and "problem" draws the press like flies on [a banana]. |

"Expect news stories shortly after, everywhere. :-) " That comment is for the very general public. I would be surprised if there is anything new to readers of the UMSF Spirit thread. It doesn't look like there will even have been any additional action (since the steering movements) taken by Spirit before the briefing.

I would love to know what's behind the "backup plan" in this other tweet: Paolo, Ashley, & I talked w/Chris Voorhees, genius designer of MER's mobility system, today. Helped us re-eval one backup plan.

I'm curious, too, though won't be surprised if there are several backup plans. Lots of lessons learned from TeeBee, I'm sure.

I don't remember seeing any estimates of how far back along her path Spirit needs to move to have all five working wheels on solid ground. Does the thin crust over the bright, dusty material extend further back than the visible piles of powder excavated by the left hand wheels? Presumably she needs to get away from the crater that she's dug into. And we finally have a map showing the outline of Scamander crater ("Scamander plains"), with the latest Spirit map update. With the crater taking up a sizable stretch of the middle of West Valley, I wonder what the approach would be if we drove out of Troy forwards (northwards). Would they continue to VB/G east or west of Scamander? |

Sure hope you're right, Eduardo. If that thing's at all mobile, it shouldn't be a factor in the extraction after all.

With the crater taking up a sizable stretch of the middle of West Valley, I wonder what the approach would be if we drove out of Troy forwards (northwards). Would they continue to VB/G east or west of Scamander? Now that we know of Scamander, we can see it... but we didn't before been stucked. I think I can see more crater-like features ahead in the 5.4Mb route map. Assuming Troy is "inside" a crater, I'll choose to drive on the "rims" of the craters to come whatever main direction will be selected. This means will have to field prove that what we can see from MRO is what we actually can predict from Navcam & Pancam picts. I'll be intersted to know if you see crater-like features ahead as I do. -------------------- |

Yeah it looks to me like the perspective has changed a bit and everything under the rover has shifted over a bit, with belly rock staying in place relative to everything else. Hard to be sure though.
In terms of the press briefing, I don't think we've heard definitely what the primary extraction plan is. That would be something to listen for. |

What time? NASA will host a media teleconference at 1 p.m. EST on Thursday, Nov. 12, to discuss attempts to free the Mars rover Spirit from sandy soil where the venerable robot has been stuck for the past six months. Any link to this since it'll be in about 15 mn? Edited, here it is: http://www.nasa.gov/home/hqnews/2009/nov/H...ck_telecon.html -------------------- |
