While searching for missing spacecraft, I found....

I don't know what it is, I was searching for the Mars 3 lander, into view comes a large white spherical object.

Kevin, a long time back, I said we have thousands of eyes on this forum. Well, I admit, there are less than thousands, but Kevin, you have FOUND the lander. I knew we'd find something. I googled Mars 3 Lander, that HAS to be it.

Hi, John, I don't think it is the Mars 3 lander itself, I think this object is too big, perhaps some other bit of whatnot from the spacecraft. I was looking for something smaller that looked like luna 9, a round body with 4 unfolded petals. This object is near the top left of the image. If it is a bit of Mars 3, then the lander and parachute shouldn't be too far away.

The object is about 10 pixels across, image resolution is minimum 25cm per pixel, so it is about, 2 meters or 6 feet across.

I have sent an email to the HiRise team and the good folks at the Planetary Society, notifying them of the image and the objects location. I'll let you know if it is just a rock or something good.

Thanks, Kevin, I'll be looking at this thread.

Something else, I remember reading it landed in a terrible dust storm. Remember the scuzzy image it sent? The parachute might be far far away, due to high winds.

Kevin,
The size is spot on for Mars 3 with solar panels not deployed. That could explain the loss of comms. But even is this is just a high reflectance rock the find is a tribute to your eagle eyes

A very angular appearance in the few pixels seen in a glare condition. This was a view of your processed image, I'll try to match the item in IAS viewer. The shadow looks rounded. Perhaps the angular rock is up against a reflective body? The bright glare actually has a two part appearance upon magnification, but only two oblate ovoids begin to appear. Could it be the lander on edge at a tilt. among rocks?
Was there a communication about the level condition of the lander, or any antennae angling details sent in the landed condition?

The reflective glare on the left and upper side appears more broken and detailed in roughness.

I hope this isn't too much noise for your topic. The color JP2 shows a directional movement which has caused a possible unstable set of features. In the first image the crater substance has moved off the circular feature marked in red across the diameter, travelled downward, and passed beyond the semi-circular rust colored margin, leaving a complex 'melted wax' set of features lower than center of the image frame.
The light is arriving from the upper left.
Size is 1 to 2, location x=5500 , y=17600.

This image indicates material flowed top to bottom, toward the next image frame. There is a separation between these two images. Any liquids or melt solids would be travelling some distance to the image below.

The image below shows a single erosion override of the arcing sweeps of ridge and depressions. Active surface erosion has broken the pattern and travelled again, top to bottom, rather than following the topographic shaped features. It is a gravity path, of a relaxed and gravity controlled nature. Some of these channels appear to be following the center of larger features lower in the JP2, at some greater distance, but this is non-standard in the scene, and follows a gravity overriding path for a distance. It appears to be a liquid flow type process down-slope. he scene has a general down-slope direction in appearance, top to bottom. Evidence of the capacity for liquids to erode the scene at some timing, and shows a surface of unstable topographic tilt.

I haven't used the grayscale JP2 as yet. I understand your 'x,y' location is related to that image pixel count. The location has plenty of dangers for a lander. Many small flow spots have ponded at other areas in a down-slope travel. It may be a very unstable surface.

Hi Dana, I don't know which image product you are using, I can't find that on the full JP2 at those pixels. Ice cream comes to mind.Like the ground is on the go and it's taking the crater for a ride.
I found another interesting structure in that image. PSP_006154_1345_RED.NOMAP.JP2 Well, maybe a couple, but one

is like a long sinuous ridge, it has opened in the middle of the ridge, like two ice flows crushing together and folding

upwards at the contact point.

You can find it on the Mars 3 search image at these pixels.

1:2 shows a crater with a completely collapsed rim that now looks like a moat around a plate.

Okay, while looking for your sliding crater, stopped dead in tracks by finding a shape close to what I was originally
looking for before seeing the big round white thing.
A white star shape.

First, so we can all see the target we are searching for up close.

Again, there is only a very slight possibility of it being Mars 3, but.

I never spotted that the first time.

Hello!
I`m new here.
I tink its a stupid question, but where can i find these High-res photos of the Mars 3 lander where you all talking about?

Hi Dennis, you can access the "High-res photos" at the HiRISE website

This specific observation is available here

To access the jpeg 2000 data (which is the real HiRess image source) you will need the IAS viewer (Java) which is available at the HiRISE website.
