MPL will have to wait until Southern Summer I presume - we should know where it is FAIRLY well from tracking etc. and we know we should be able to find a parachute VERY easily, as well as Backshell and Heatshield. As for the lander itself - slightly smaller than the viking spacecraft if memory serves me right - and likely to be a lot 'shorter' (i.e. crushed landing legs etc ) - and if there were any 'splat' mark from leaked fuel etc - i would have thought that 3 winters would have eliminated much if not all evidence of that.
Beagle 2, well that supposed MOC target would be an interesting starting point. How far B2 got through its landing sequence before failing will dictate how much 'stuff' is on the ground. The Chute - if 'entry' worked - deflated airbags should be visible as well, if it got further than that. The heatshield, backshell and indeed the lander itself - I would say no - going on the sim I managed which seems to be something roughly indicative going on MER experience...http://www.unmannedspaceflight.com/index.p...ost&id=8409
As for pieces of the historic Russian landers - I would be doubtfull. They were comparatively small, and their Parachutes and indeed any other hardware- if anything like V1 and V2's chutes - will almost certainly be dust-covered and hard to identify.
I am new to this blog and this forum....I want to help find the MPL....actually anything up there that man sent....but I always wondered what happened to that
particular lander. It was expensive. It promised so much. It just disappeared. Like everyone else I would like to know why.
To try to understand what is involved with the search, I have been looking at one of the HiRISE Images assigned to the MPL Search.
I agree with comments made by tuvas.
I have to say that trying to find a Mars Lander or wreckage of same on this series of HiRISE Images is going to be a massive undertaking, even if you do know what you are looking for.
As part of my job I view RT Films of welds and you really need some experience to accurately understand what you are looking at.....same case here.
The Zoomify Viewer provided on the HiRISE site is pretty good and I am astonished at the resolution which seems to me to be much better than 25cm per pixel.
I wish it had a grid overlay that you could tick off.....something like that to keep track of what you have looked at. Also some sort of reference coordinates linked to the cursor
which would give exact location so others can easily and quickly find and verify for themselves.
Frankly, some of the images I am seeing, well....I have no idea what it is I am looking at.....I have found a number of objects that look like man made wreckage to me.....
(I have posted these 23 images in an album with comments on the following site for anyone interested....http://www.facebook.com/photo.php?fbid=260...e=1&theater
All objects are from one picture PSP_005301-1030) but look at these HiRISE images long enough and after a while you see all sorts of things. I will be adding to
to the 23 images as I find more in the debris fields I think I am finding.)
I found these objects just by trying to identify things that stood out as being different from their surrounding terrain using a complete scan at
20M resolution and then zooming in further for confirmation. The Images are naturally very blurry and it's only to be expected.....I have no
image enhancement software beyond Photo Impact 12 and that doesn't improve these images. These are only PrntScrn captures via Photo Impact 12
to get to .jpg images that I could post on Facebook. The were always going to be degraded.....sorry. It just show the difficulties
beginners have to cope with when they try to interpret images and then submit them for consideration.
To aid radiographers when they review RT Films of welds there are often reference images showing the appearance of typical defects.
Something similar to guide novice interpreters would be invaluable.
One of the hardest things for people to do is identify things from above as opposed to head on or from the side. There are clearly people
on this blog with considerable experience who are in a position to easily identify the MPL as well as Martian terrain......
It would be very useful if that knowledge could be passed on in some way to beginners and even other more experienced searchers.
Finally, someone has to look at images of submitted possible MPL crash sites and say "yea" or "nay"......
In the interests of sifting out the spurious stuff and giving the idea of what might be right, it might help to have a
"Hall of Blunders and Possibles" Site with all the pics annotated with verdict and their location clearly indicated on the HiRISE Image
of concern. For example, someone may have found the same things I have on PSP_005301-1030 and they have long ago been
dismissed as non-starters. It would help tremendously with realizing efficient use of time and effort.
In the case of the Mars Polar Lander do we know if the heat shield and back shield and chute detached. I ask because one of the
objects I have found looks like the MPL sitting on it's Heat Shield, back shield present but displaced, with chute still attached
....please note I didn't say is.....just looks like.
If we know the heat shield and back shield and chute detached what I have found clearly isn't the MPL ....just something that
looks odd. I am going to post some images of this possible MPL and other anomalies here just to give you an idea of what I
am talking about and give others an idea of problems with image interpretation......other details are on Facebook if anyone needs more
information about location and so on to check for themselves. I have not messed with these images beyond
labeling, adding arrows or outlines or zooming in even more....I all cases I recommend going back to the Zoomifierhttp://marsoweb.nas.nasa.gov/HiRISE/hirise...SP_005391_1030/
The control panel takes you down to a view with 20M scale. Right clicking gives you the option to zoom in further.
One last point...something you said.....I do agree that sands may cover wreckage of old Russian landers but also winds blow
sand away from covered objects here on earth particularly after large dust storms. Might that not happen on Mars?
Large areas of the Image I have searched on my first HiRise Image showed little signs of sand drifts, just lots and lots of
rock formations of various types (I think).
It can work both ways I think....hope.
It would be amazing to find those old Russian Landers and MPL...in fact any of the old space debris. Just to get something from
Earth to the Martian surface regardless of whether it worked or not, is a tremendous achievement and an important
monument to the amazing technology and scientific achievements of man and stupendous efforts of thousands of
Earth's brilliant and best and each debris field is maybe worth pinpointing on the Map of Mars. Also....it would stop them being
