smile.gif Thanks to the MRO the Viking Lander 1 site has been viewed twice already at nerly the same Mars local time :
- PSP_001521_2025_RED.jp2 taken on 11 November 2006 (w/30.3 cm/pixel resolution) at 3:20 PM ;
- PSP_001719_2025_RED.JP2 taken on 12 december 2006 (w/28.8 cm/pixel resolution) at 3:27 PM.

So I decided to pixel overlap the 2 pictures retrieved from the LPL site at their maximum resolution (as "full JPEG 2000" images), knowing that each individual pixel from those 2 images would not cover exactly the same area on Mars.
The goal was :
1. to gain some resolution over individual pictures ;
2. to assess the reality of some features as seen from orbit ;
3. to determine is some individual Lander components could be seen ;
4. to see an "average" site free from bad pixel and false features.

After a painstaking process, here are the results on the 4 goals :
1. resolution gained : ==> not obvious on overlap image ;
2. reality of some features : ==> real features are seen on overlap image ;
3. Lander components : ==> some individual components discriminated ;
4. "average" site free from bad pixel and false features ==> goal attained.

About the lander itself : the shadow seen for its high-gain antenna mast and for its antenna itself is narrow. This implies that the disk-shaped antenna was not facing the sun when the images were taken, meaning that the high-gain antenna is pointing either towards the north or towards the south.

The same overlap processings were also applied to the area where the backshell touched down the surface with its parachute ==> An overlap image is seen also.

About the landing site itself around Lander 1 with its features, please refer to the explanations given it the previous post :

...So I just merged the final RED hi-res panchromatic image (see hereabove) with the color product found on MRO's website !
Now you see the VL1 site in full color at its maximum resolution...
Enjoy ! smile.gif

This is a great image! Historic, even. I think the Viking 1 site is right up there with Apollo 11 as a place where we pushed forward as a race. Good work!

smile.gif Thanks a lot JRehling for your kind comments !
...And here is the "basic" original color HiRise image from which the final color overlap (see hereabove) was produced (it has less resolution/pixel) and after final color calibration of course (deleting also the blue halo around VL1)...
Enjoy also ! rolleyes.gif

Great!
I made this modified version in order to improve contrast/pixelization/color... (I do not know how much realistic is, however unsure.gif ).

Looks shiny to me... wink.gif
So...when we will see Phoenix will we be facing an image with similar characteristiques?
Doug, one of yours simulations would be really appreciated! smile.gif

Phoenix will be EASY to spot - very very easy indeed. I did a simulation just over a year ago ( Bottom of http://www.planetary.org/blog/article/00000840/ ) - but it appears, from above, about three times the size of MER. Basically, imagine two MER's with a brighter disk parked between them.

And to be honest, claiming that HiRISE has degraded significantly is just not true. The most recent image of Spirit ( from January ) is as good (and infact, imho, better than) as the very first ( from Nov 06 )

THANK you Doug! biggrin.gif
I'm really excited about it...this is, believe or not..., my first martian landing... smile.gif
I've only followed MER after thwey reached Mars... rolleyes.gif

Oh Rui, Rui, you poor thing... I had no idea, I'm sorry.... wink.gif

Boy are you in for a treat. Well, when I say "treat" I mean, of course, several hours of gut-knotting tension and worry, as you sit at your computer, staring into the monitor, your increasingly-tired eyes focussed on that little media player screen, helplessly watching people thousands of miles away helplessly following events millions of miles away. You'll watch every face behind every console for signs of success or failure; you'll hiss "Shut up!" at any commenator trying to describe what's happening because they'll be talking over "the good stuff"; you'll feel like an idiot whispering "Go on... go on... " as the seconds tick down to landing itself, and then feel absolutely lost and useless as the time delay leads to that awful wait before confirmation of a safe landing is received. And you'll shamelessly shout "YES!" - and might even do a silly little dance... not that I did (cough) - when the first picture comes in and you realise that we're Back On Mars... And when there's nothing "new" to see, when you finally leave your computer and step outside into the sunshine you'll let out a long "Thank **** for that...!" sigh, but you'll also have a ridiculous grin on your face, wondering what fascinating and amazing sights the next day will bring... and the day after that...

Some tips: You'll not want to miss a minute of it, not want to leave your chair for longer than you absolutely have to, so make sure you have snacks and hot drinks ready and around you. Be wary of logging off NASA TV because you might not be able to get back on again, there'll be huge demand at the time, and you don't want to be locked out as the big moment approaches. You're going to get tired, and there'll be stretches of time when nothing happens - or is appearing to happen - so have something else to do if you need it, just so you don't lose concentration, but do NOTHING that could jeapordise your link to NASA TV!

But most of all, try to be patient, and take nothing for granted. Landing on Mars is hard, and dangerous, and it's easy to forget the losses of Polar Lander and Beagle when we're being spoiled by daily images from Oppy and Spirit. I don't envy the Phoenix team sitting there at their consoles, going through all this for real. Mars is a planetary Shrike, it's killed more spacecraft than it has let live, and all we can do is hope that Phoenix is allowed to land safely.

Hmmm, here's a thought... how many people here will be watching the landing "Live"? Where will you be watching from? Sneaking a peek at work? Watching from home? I'm sure there'll be a lively real-time discussion here on UMSF as Phoenix descends.

Tick tick tick...
