Some L2/L7's came down and I've done a whole lot of channel-mixing to get something fairly nice.
http://www.unmannedspaceflight.com/doug_images/o533_71.jpg (600kb) And because it highlights the features ahead so brilliantly - i've done the interesting section in 500% Phil-O-Vision http://www.unmannedspaceflight.com/doug_im...o533_71_pov.jpg (60kb) Who wants to play 'match the feature' with that and MOC imagery Doug |

Lovelly picture Doug. After all this waiting, I hope Erebus turns out to be more impressive than Vostok lol. I've often wondered where Opportunty might be right now if it hadn't got stuck... although I suppose it could have got into trouble on a dune further down the line.

Looking at the Phil-O-Vision image I thikn Erebus could actually be a nice panorama - several feet of outcropping it looks like. A strange, new, and unusual vista I am sure

QUOTE i've done the interesting section in 500% Phil-O-Vision Yes! You can already see dunes and ?outcrops? of the dark "basal unit" within Erebus. QUOTE I've often wondered where Opportunty might be right now if it hadn't got stuck... I think that getting stuck was inevitable. Oppy was travelling uncommanded at high speed and the conditions/terrain were clearly changing before she got stuck. The Purgatory incident was a wake-up call; it could have been worse. --Bill -------------------- |

I'm curious - is everyone else seeing this (and many other Meridiani panoramas) as nearly black? I have to enhance the intensity in order to actually see what's going on. Is this an aesthetic choice, to match a perceived expectation of the actual lighting at Meridiani, simply a matter of preserving the intensity from the original images, or do I need to adjust my monitor?
Incidentally ... with the intensity enhanced, nicely done, and it's good to see Erebus. |

It's far from black on all the systems I use...CRT's at work ( two different ones ) LCD on my laptop, and LCD for my home machine
Perhaps you need to fiddle with contrast/brightness? Doug |

Here:
I compare views of Erebus from sols 448 and 533. The first was my original posting, the second cribbed from Doug. My impression is that on 448 we could see a bit more to the south, as if the rover was then up on a slight rise, and now the view is from a slightly lower area. This may explain why we have had so much difficulty seeing anything. I have always thought the etched terrain should be very interesting and scenically attractive, but it's one of those things you don't see until you are right on top of it. As for matching this to MOC images... I'm not ready to do that yet. Got burned with Home Plate! Phil -------------------- ... because the Solar System ain't gonna map itself.

Monitor settings have always been a problem with digital viewing. Perhaps we ought to have a "monitor calibration" page onsite; here is the calibration page from my site: http://www.mindspring.com/~woharris/cal.htm Doug, PM me if you'd like to use any of these materials here. --Bill -------------------- |

My contrast was off. Much better now |

Phil, I think you're right! In fact, this explain also why I wasn't unable to make decent vertical projection from Sol 531 partial panorama... : looking to tracks divergence, I things that in that Sol Oppy was descending... -------------------- I always think before posting! - Marco -

Here is an interpretation of Doug's o533_71_pov.jpg image. I used PaintShopPro to set the grey, white and black points of the image to remove the "mars dust" color bias from the image. In this way one can see compositional differences in the surface materials by "dusting".

According to the latest flight director update Opportunity will only be 150 meters from Erebus crater after todays drive (SOL 536)!

Heck with Erebus: Victoria ho? Is anybody else thinking that the little 5-6 pixel rise immediately to the right of Erebus looks a bit hazy, as if from distance, and is in exactly the right direction...?

If you look to traverse map, this is impossible: From actual position (in red) Victoria should appear about 40deg east of Erebus, approxiametly between the two red marks in this stretched Doug's panorama: Probably, Oppy is too far (and even in a depressed region) to see Victoria rim... the feature you highlight is the Erebus rim... -------------------- I always think before posting! - Marco -
