I'm still puzzled by such a big cleaning by Venturi effect knowing how thin the atmosphere is.


Well the dust on the panels is airfall and ultra fine (I think SQ made an analogy to cigarette smoke) so it should be easy to loft with increased windspeed. But there is no real evidence that this event was anything more significant than dust devil action - particularly given the large DD animation on the Spirit thread.

My favorite quote in this MER update:

QUOTE
The big news – and the best news – from Meridiani Planum this month though is that the team has found a way to mitigate the elevated currents drawn by the rover’s right front wheel motor. “The currents have been more normal than we’ve seen in a long time. While we still see some elevation in that right front wheel current, especially on turns, overall the driving was pretty stable this month.” Laubach reported. That comes as real relief, especially considering that Opportunity still have some 15 kilometers to go to get to Endeavour.


And my all-time favorite:

Anyone have any ideas as to what this "way" to mitigate is? Does it involve programming it to turn with the other wheels and leave that one alone?

If Occam had heard my theory, things would be very different now.

I believe it was adding heating to resting to re-distribute the lubricant that has yielded these better results.

The story was originally posted in the wrong year -- I've edited the various links to make them work.

A few highlights:

QUOTE
“We’re going to try and beat MSL to find phyllosilicates,” Arvidson announced.

QUOTE
“The wheels are very well-behaved,” reported Callas. “We’re quite pleased with the current levels of all the wheels.”

QUOTE
“The rim is connected and the northern part that is closest, Cape York, and the surrounding hydrated sedimentary rocks at Botany Bay, where we are heading, are on a lower part of the rim, so we just cannot see them yet,” Arvidson reminded.

About this last quote, have we heard a reference to Botany Bay at Endeavour before? They seem to agree that York is somewhat inside Endeavour.

Update for March end (2011) includes fascinating read on hailing Spirit as well as our Stu!...

(sorry if wrong thread but references to A.S.J. Rayl's wonderful monthly P.S. updates are somewhat scattered!)

There is a small error in the article, R. V. Morris is referred to as both "Richard" and "Robert"...
