The HiRISE camera can see Martian objects smaller than a meter, and was able to spot the hardware that the rover needed to land safely on the surface (click the links to see them in higher-res):

Upper left: The heat shield ejected after safely protecting the whole lander package in its initial descent through the atmosphere.

Upper right: The splash pattern from the sky crane; the rocket-powered crane that hovered over the Martian surface, lowered the rover to the ground, then blasted away. The crane itself can be seen as a dot in the full-res picture.

Lower left: The parachute (lower left) and the back shell that attached it to the lander package. The parachute slowed the rover and sky crane from super- to sub-sonic speeds.

Lower right: The rover itself, barely resolved, but proof that humans are once again by proxy on the surface of another world.
