Huge thanks to the guys that helped transcribe this. I wanted to do something a bit better than just copy and pasting into a word document, or into a forum post - but I'm no graphic designer. Thank goodness for Publisher templates smile.gif Hopefully the result something you'll all like. The odd bit I've edited just for the sake of readability - but it's 99.9% as on the audio.

Any Typos and Spelling errors, please write them down and....put them in the bin smile.gif I've got bags to pack wink.gif

Enjoy

Adding my congratulations.

The Front Page shows 30 visitors just now, while usually it has been around 5 - 10 at this time.  I would guess the AvWeek cover has brought this forum to a much wider audience.

Well, the site doesnt actually get mentioned (at least I dont think it does) - but Nov 11th was the busiest day in the sites history.

I'm not a big fan of K.C. - but the 'big' image also made it to..

BUT - Genesis worked - most of the samples, and all of the critical ones, survived fine. There was a delay to, but no loss of science.

Minerva was a last minute thing iirc - given that JPL was devloping a rover for Muses C but cancelled on them.

He has phases, 6 months ago it was the Discovery program on the recieving end - despite giving us Deep Impact, NEAR, Pathfinder, Genesis, Stardust, Lunar Prospector and Messenger, and only one total failure, Contour.

Actually - it IS what it would look like with human eyes - to the best of the scientists knowledge.

They HAVE done the calculation using L2 + L5 to get L4 - believe me a panorama done with straight L256 looks utterly utterly horrible and nothing like the Athena release at all

QUOTE (ugordan @ Nov 14 2005, 01:00 PM)
Why do they insist on using the infrared channel


Because it give a lot more spectral variation to the scene - you get SO much more information from an L2 image than an L4 image. L4 images look very flat, with little of high contrast.


QUOTE (ugordan @ Nov 14 2005, 01:00 PM)
and labeling the final product as true color? I find the official Everest panorama way too red, and that sundial pink chip definitely doesn't add credibility to their "true color" statements.  huh.gif
*


They've not said true colour. They've said APPROXIMATELY true colour. You can 'emulate' an L4-like filter using L2 and L5. Infact Bjorn has done the maths to do just that, and the two are very very very similar indeed. The end resulting mosaic is very little different - if at all - than if it had been taken with L456 instead of L256 - but in taking the L2 channel, they get a lot more information, and a better 3D terrain mesh as there are more feature to co-register between frames.

QUOTE (JPL website)
This panorama spans 360 degrees and consists of images obtained during 81 individual pointings of the panoramic camera. Four filters were used at each pointing. Images through three of the filters, for wavelengths of 750 nanometers, 530 nanometers and 430 nanometers, were combined for this approximately true-color rendering.


QUOTE (Pancam website)
The panorama spans 360 degrees and consists of images obtained in 81 individual pointings and 4 Pancam filters at each pointing. This mosaic is an approximate true color rendering generated using the images acquired through Pancam's 750, 530, and 430 nm filters.


The pink chip is a well documented, well explained result of the near IR response of that colour pigment - it's a specific feature of that chip - http://www.atsnn.com/story/30048.html explains it very well indeed.

Hayabusa, for instance, is a much more complex mission than NEAR -- being done with about half the money.


And they've achieved much of what NEAR achieved on much less money. That deserves a lot of credit.

I know that they're slowly increasing all the storage for Gmail - it used to be a gig, then 2 gig, and now it just grows with time. Perhaps the same is true of attachments?


I dont use Google Earth - I just use Google Maps - smile.gif

http://maps.google.com/maps?q=32%C2%B0+9&#...19406&t=k&hl=en
I think is where you mean -it's an amazing place. I saw a documentary by Jeremy Clarkson about it once - trashing B52's with concrete blocks. Hundreds of Harriers, F15's, 16's - just about anything you'd want - enough to arm an entire nation... - go down and right a little from that link - and you can see B52's - Unbroken and Broken in rows.

This place amazes me as well

Unfortunately, I dont have a the words to express the joy of the past few weeks waiting for this - but it's been awesome, particularly with Ken, Bernhard and Marco - all working as a team

It's the 'cheekiest' Navcam mosaic I've seen done - using imagery from Left and Right cameras to 'patch up' where the perspective caused the LGA to 'rip' half way down, but the end result is something we're all proud of.

Cool isnt it smile.gif

Could be simulated with Orbiter if you knew the right info.

Thinking out loud - how much of it might it thru to the surface - perhaps the prop tanks ( Delta II 2nd stage prop tanks make it to the ground here on earth ) - but not a lot else I'd imagine.

We all know where you mean by the other place, but to be fair, as the 'out there' discussions go, it's probably the most sensible of them. A few utter loonies, but a few people who have atypical theories yet present them in a reasonable way.

Problem is - you cant do that sort of discussion at the same time as more mainstream discussions - the two are mutually exclusive. I spent far too long learning that.

I think the 'attracting kooks via google' thing is a lost cause anyway - we talk about mars, spacecraft, rocks, we're going to flag up on Google with those sorts of things.

So to flag things up because they might attract kookiness (instead of actually being it) isnt a fair judgement - on that basis we might as well delete every MER image on the whole forum. And all the Cassini imagery. And the Viking. Actually- we might as well pack up and go home.

This discussion itself remains an interesting one, but isnt in the realm of kookiness in so far as no one is suggesting vast martian civilisations and all that garbage. Infact, if someone stumbles across this thread, it's a good thing - we've explained what it is - a discared piece of the entry system. It's also good because it actually shows what an artificial feature looks like on mars - they stand out rather well. So this thread is informative in a good way.

However - if people have issues with particular threads - it's no use saying "there's more kookie threads" - you have to tell me which threads. I cant read everything here anymore, it's too big. I have things to do like eat, sleep, work. If you think a thread, or particular posts or a particular poster are crossing the line, then tell me, specifically.

One poster has just returned from a 30 day account suspension for it, one ex member remains banned from the site all together, as does his IP address from the entire domain. I am perfectly prepared to take strong, rapid action where necessary - but I'm not going to delete every thread that says Face, Feature or Fossil

I have a metaphorical benchmark in my mind. If I see a post and I can imagine copy and pasting it to an anolmalists website, then it's over the line. To date - despite >1.6 million thread views - no one has started posting a verbose analysis of JPG noise. When that happens - myself and the mod team have a big bat marked "OUT" ready to go.

Hayabusa's goal is to return a sample from an Asteroid. It is not a failure yet.

http://www.jaxa.jp/missions/result/rocket-result_e.html
Not all "ridiculously bungled" as you insist.

Given the budget, Hayabusa's achieved astonishing things already.

I find it a bit dissapointing that the flatfield/darkfield work etc hasnt already been applied to Cassini imagery as it has with MER imagery that gets on the PDS as RAD's
