As well as the corpses outlined in red discussed above, the expanded Op Sol 4183 file shows another dead astronaut outlined in white .. there appears to be the tattered remnants of clothing, the left foot, ankle, exposed knee joint and exposed pelvis are visible.
The right leg is bent at the knee and tucked back, the left arm is bent at the elbow with the left hand roughly aligned with the kidney region, the right arm is bent at the elbow with the forearm resting on the right thigh, the head appears bare.
Take another look at the "Third Astronaut" insert .. there are two figures, the one at the back outlined has the same crossed bandoleers uniform seen in the second bottom shot, he is cradling the skeletal remains of another human figure, whose bare bony left knee joint and exposed leg bones lie over his uniformed left leg, the skeleton's right leg appears to be missing.
The triangular eye sockets identify the figure to the left as a native Martian.
The same crossed bandoliers uniform worn by the Martian figures appears in Adam Strange and Flash Gordon comics from the 1960's, which bespeaks alien intrusion at DC Comics, else how did they know genuine Mars Rangers dressed like that
We discount the proposition the "Astronauts" were space travelers who were marooned in situ, and seek another explanation re how four ppl came to be "staring at the stars" on a bare hillside on planet Mars. Perhaps the crossed bandoliers are a sign of authority, that these were rogue members of the ruling elite's police apparatus.
Who were evicted from their underground base and abandoned to their fate on the surface! The familiar manner in which the uniformed figure is holding the skeletal body in middle set, brings with it a suggestion of sexual proclivity .. maybe unlawful coitus was at the root of the affair.
