Just how does it end up costing $4.5B ( which will become $5B I'm sure)

That's just - wow. That's TEN Mer's.

TEN

I'm not saying "drop the scope, build Ten MER's" - but even the challenge of getting that mirror light enough, and deploying accurately enough surely cant cost $4.5B

No - there was a drive -

These new images are site AE drive 00

The previous images were site AD drive ND

Not to mention the fact that the F/RHAZ shows driving smile.gif

I take it you seperated the layers in photoshop and shifted them about rather than having access to the original raw images.

Yup -just moved the channels in photoshop

If I had the raw data - I'd be shouting about it smile.gif

Can anyone spot Larrys Lookout in this lot? It's a bit confusing down there.

More images after another drive

It probably makes no sense - but to see the horizon over the summit, from Hazcam pics is a watershed as far as I'm concerned

Well - sad thing is that a little brush mark wont last very long.

The rat may be dead - but I'd use it anyway - just to grind a mark in a rock if not a proper rat hole.

Otherwise - perhaps a trench?

Here's a cunning point for you

If you can find a red LED a green LED and a blue led around - have a look at them.

You cant focus properly on the blue one - wavelength if just a bit too far over for the eye to focus onto the retina

Well - I can see why he might be nervous - certainly inside the 3m point at which Pancam gets nicely focused (hence the 2:1 downsizing of all the deck-pan selfportrait images ) - but if Jim says pancam will do X ...pancam will do X+1 smile.gif

I was amazed to find that those first few sols were using really slow UHF passes - no wonder they compressed-to-hell those first pancam octants.

Pity that the media abandons such missions early on - as the success pans were the lowest quality of the lot ohmy.gif

Arhgh - those codes on the DVD's had Helen and I going nuts smile.gif

You got a good deal mind you - as the Spirit one was imaged twice I think...

Sol 2 - You got a REALLY sharp L4, highly compressed L5, a 2:1 downsampled L6, and a nice L1.

If you make a colour image from the L456 - then overlay it onto the L1 - you get great results.

Bog standard L456
http://www.unmannedspaceflight.com/doug_im...pir_dvd_456.jpg

L456 as colour over L1
http://www.unmannedspaceflight.com/doug_im...r_dvd_456x1.jpg

L456 and L1 stretched a bit - and multiplied
http://www.unmannedspaceflight.com/doug_im...dvd_456x1xD.jpg

One problem is that it's just short of being in focus - it's a bit too close to the pancam.

However - sol 37 comes along and we get L24567R2 - all full res and with mild compression

The 456 comes out as
http://www.unmannedspaceflight.com/doug_im...r_dvd_2_456.jpg

and an L2/R2 anaglyph

Meanwhile, on the other side of the planet wink.gif
Full sized L1 and L4, but this time downsized on both L5 and L6

Sol 12 - Oppy got another shot

http://www.unmannedspaceflight.com/doug_im.../opp_dvd_12.jpg

Sadly - in the part-taken L4,5,7 mosaic
http://www.unmannedspaceflight.com/doug_im...nest_mosaic.jpg

The DVD isnt there - it's off to one side.

All this is on the Planetary Soc website - but it was fun to recreate it all myself as well - ahhh...sol's in single digits..those were the days



That was a fun blast from the past.

Dont think much of their co-registering of the R,G,B's for that - it's a bit off smile.gif

This is perhaps a smidge better

Well - I'll be nice and let the questions run over a little - but 4 pages of them is plenty smile.gif

Today - my copy and the best-question-prize copy arrived from the US - and actually -it's a very 'nice' book - nice paper, binding etc. A scrawl from SS will look good on there smile.gif

The best question I've seen asked is regarding using different filters in L and R simultaniously to get pseudo colour of the dust devils - but there's some nice ones in here.

Here's a challenge - what would you propose to fly in '11?

With 350-400 $M - the options are limited. An orbiter on the scale of Odyssey would drop in well under budget - a lander is going to be difficult .

I think I'd try and do SAR, and if possible, squeeze more downlink out of it - something up to 288 or 512 kbps would be an achievment.

QUOTE (helvick @ Aug 21 2005, 07:24 PM)
he highest quality imaging is done with one filter, additional images are for geological science data\context\colorizing and don't need to have the same resolution so they are downsampled. I don't think it's wavelength dependant it's a planning decision that maximises the science data returned.
*


That was done way back for the mission success pans for both rovers - the L2's were full size, the L5's and L6's were half res. But that's when they were unsure about UHF performance and only doing 32kbps. Now that they do 128 or 256kbps they can forgo that data-saving tactic.

I think it's just that things are not quite as sharp in the near IR perhaps?

As Jim Oberg described them - Cultural Vandals. Nothing more. Hoagland is the same - just attention seeking.

Sorry - I know what you mean - but it also means people can post stupidly long sigs with system configs, flash movies, big images etc - it's just all pointless.
