Volume 8 of the LRO data is available from the PDS Imaging Node. This should contain the latest Apollo landing site images that were taken from the lower orbit.

Those spectacular low orbit images can be seen (and the raw files linked to) from here:

There are a number of blobs of saturated pixels in the vicinity of the Apollo 11 descent stage, particularly downrange (to the left). Some appear to be boulders, in that they also cast shadows. However, others are just small areas of saturated pixels that resemble the reflection from the discarded experiment cover near the LRR and PSE. Could these be pieces of Mylar/Kapton blown out when the ascent stage took off?

I see one big piece almost exactly due west at the extreme edge of the image. I think your explanation is correct -- there must have been a lot of that stuff blown off. We saw it in the lift-offs on TV for 15, 16 and 17 but not the earlier flights. Of course, the effect must have been exactly the same although not witnessed on 11.

LRO recently imaged the Luna 17 lander (that delivered the Lunakhod 1 rover - also imaged)
Here is a processed image of the lander. The rover's circular tracks (to take 360 pans) are quite nice! (... are the complete Lunakhod 1 images available someplace?.... Mr. Stooke? ...) -------------------- CLA CLL

I thought there were ramps on both sides of the lander, but if I am interpreting the image right, there appear to be only on one side. Can someone explain this?

Here is the LUNOKHOD 1 rover from the same recent LROC image
(Note: Image of lander 2 posts ago.... Hungy4info... my guess as to why we see the east ramps (so bright) is the sun angle and the reflected light from them. The westward ramps are in shadow and are 'averaged out' by the camera. You can see 2 dark appendage shadows on the west part of the lander. These are the darkened ramps, they don't return enough photons to the camera to be imaged properly. The bright ramps are screaming photons upwards, and over-imaged (they are not that big), the camera sees them as blurry ... just a guess) -------------------- CLA CLL

i have been doing this for other images so in a break a TOPO "bump/height map" of the above "Luna 17" image
the text was software in-painted the 32bit float then converted to a jpg [attachment=26593:moon_dem2.jpg] the above lunakhod [attachment=26595:lunakhod.jpg] |

John VV - nice topos!
Centsworth -- you said in half the words, what I meant (!) Nice lander image! Here is a zoomed image of the Luna 17 lander. Reoriented (left becomes right) so that sun seems to come in from the top left corner (it seems to give more perspective? or it could just be my internal preference for light coming in from the left!) notes on processing: I tried something new... in order to try to reduce the blackest shadows and whitest glares, I found the median DN in the base image, and then for each pixel, added box-mueller noise (mean +10, sigma 7) if the pixel was below the median, or b-m noise (mean -10, sigma 7) if it was above the median. The +10/-10 on the b-m mean, increases/decreases the overall brightest below/above the median. I made 12 images with this stochastic noise (computed for each pixel). I then did a 3x zoom (each pixel, with rational noise, now becomes 9, based on the DN info of many noisy neighbors, i.e. a b-spline zoom) and then I stacked the 12 resulting images. This averages the pixels towards their new means (shifts the histogram), normalizes the added noise, and 'hallucinates' new (but probable) info into the zoom. It wont change the shape of the glare, but it should add detail into the whitest and darkest areas. (... we now return you to your regularly scheduled forum!) -------------------- CLA CLL

Here is the LUNA 24 sample and return lander.
It landed 2.4 km form the failed LUNA 23 lander and completed the mission! Luna 24 collected 170 grams of layered material from the edge of a crater (bottom right) The top 1/3 of the image in the top right corner is the ascent stage. -------------------- CLA CLL

I would like to introduce you to one of the most interesting things I have found on the Moon in a long time...
This array of hollows is in addition to the ones I reported on at the LPSC, a new observation. They are absolutely pristine, the sharp edges unaffected by any later impacts. And the amazing thing is, they are right in the ejecta blanket of Aristarchus, itself one of the youngest craters on the Moon. They have to post-date Aristarchus. Whatever form of activity created them, it was active in the last few hundred million years. Rover target anyone? The location is given at the bottom right corner of this Quickmap screenshot.

I would like to introduce you to one of the most interesting things I have found on the Moon in a long time... Excellent find Dr. Stooke! They looked like plateaus to me until I looked at another image M142570512. On second thought, I am having trouble visualizing them again. Are these plateaus or indentations? The craters around them indicate indentations, but then the mind wants them to be plateaus. Odd. |
