So which image was taken first, the top one? The 2 pictures are obviously of the same exact area & angle of it, just differing in detail intensity, so explain why it doesn't exist in the much better detailed first image you posted.

The apparent size of this object, considered to be too large to be the target marker, is only a very simple illusion: the thing seems posed on the asteroid, but it is only an effect of perspective; the probe in fact is just sent towards the asteroid, it is still close to the Hayabusa probe and not posed on the asteroid. On the following images, it naturally apparently "disappeared" since it is indeed too small to be spotted on the asteroid from this distance.
Hayabusa carried three of these small spheres, which are in fact simply inert reflective objects - hence the white aspect - with three fixation points, on which the probe can shoot a beam to obtain by telemetry its exact distance to the surface of the asteroid, for a correct automatic approach of its surface.
The probe thereafter succeeded in "landing" on the asteroid, unfortunately, the mission controllers think that the sampling operation did not function correctly. Even worse, some of the probe's thrusters seem to have been damaged during the operation, and the return to the Earth seems compromised.

The spacecraft is thought to have successfully landed a "target marker" - a small metal ball - on Itokawa
Imagery taken by Hayabusa was used to select a touchdown location on asteroid Itokawa. One newly released image shows the shadow of the spacecraft cast upon the asteroid’s surface.
25143 (Itokawa) has a number of areas on the surface that appear to be hydrological sinks. These hydrological sinks are surprising in on an asteroid, which is not somewhere we would expect to find water, but are attributed to the former presence of ice. It is thought that the asteroid may have formed further out in the solar system, where chunks of ice (not necessarily water ice) were incorporated into its makeup. At some point it was shifted onto its current orbit, where it passes closer to the sun. This caused the asteroid to heat up, and the ice to sublimate (turn directly from a solid to a gas) in a similar way to material evaporating from the surface of a comet. After this happened the loose rocky material covering the new void subsided forming a sinkhole.
