Voortgang van Apollo 15:CSM Rev. 17

There are some notable differences between these two images. Firstly, the shadow lengths have changed as the sun has risen in the lunar sky, exposing more of the surrounding craters and shortening the LM shadow. Secondly it is possible to make out the evidence of astronaut activity.
There is clear evidence around the LM of disturbed ground, as well as towards where the ALSEP was set up. The latter involved a considerable amount of activity, which explains why the large area around it is so obvious. The LRV (rover) can be seen on the upper left right above the LM. The rover took a different route to and from station 1 and 2, which is why the path is much less easy to make out.

After EVA-2: http://wms.lroc.asu.edu/a(...)age_name=AS15-P-9798 Apollo 15 crop: ![wpbdbc0b9f_05_06.jpg]()
There are two major areas of difference here. Firstly, now that EVA-2 has followed at least some of the path followed for EVA-1 the ground is more disturbed and there is now a noticeable trail running from just west of the LM south.
The next feature is the area extending from the LM to the ALSEP, which is now much more prominent.
The area around the LM is also now much more disturbed
Here’s a close up of the two of them for comparison:

The LM shadow is shorter, something that Dave Scott draws attention to as they pack up at the end of EVA-2. The LRV isn’t quite as easy to spot as before, but luckily we have two other photographs in the form of
AS15-P-9800 and
AS15-P-9793 , taken just a few minutes apart from the image used, to help clarify things.
Here they are along with a still from footage of the crew climbing inside the LM at the end of the EVA. The APC crops are rotated 180 degrees so that the roughly match the view in the video still. St George’s crater can just be made out centre right of the still. T
The astronauts are climbing a ladder in shade, but the LRV is in sunlight.

We have a view that is entirely consistent with the object in question being the LRV, in exactly the place that it should be according to the TV footage.

The shadow on the LM is considerable shorter this time, partly because it is later in the mission and the sun is even higher, but also because half of the LM is now missing, given that the ascent module has just docked with the orbiting CSM. As with the other two EVAs, we can be sure of the LRV location on this occasion as well.
The reason for this is that at the end of EVA-3 the LRV was driven to a last resting place so that it could observe the ascent module’s launch from a safe distance.
You can see the trail this created as a line heading east from the LM, and the LRV itself can be seen on the right hand edge of the photograph.
Apollo 15’s APC imagery presents us with a chronology of the activity around the landing site, revealing how the lighting conditions and disturbances brought about by human activity changed over the course of the mission.
This chronology is (as with every aspect of Apollo) entirely consistent with the documented facts.
