Early space junk
The cylinder is probably part of the spacecraft bus that delivered the
Luna 13 lander to the surface. It crashed nearby after ejecting the
landing capsule.
The long, slender black shadows in the lower right are the antennae
on the lander, not an approaching lunar spider. :^)
In a related example, check out the debris field from the crash of the
Mars Rover Opportunity's heat shield:
