Explanation:
A wheel attached to
NASA's Curiosity rover is firmly on the martian surface in
this early
picture from the
Mars
Science Laboratory mission, captured after a
successful landing
on August 5, 2012 at 10:32pm (PDT).
Seen at the lower right of a Hazard Avoidance Camera fisheye
wide-angle image, the
rover's left rear wheel is
50 centimeters (about 20 inches) in diameter.
Part of a spring hinge for the camera's dust cover is just visible in
the right corner, while at the upper left is part of the rover's
RTG power source.
Looking into the Sun
across the rock stewn surface of Mars, distant
hills on the right are the rim of
Gale Crater, about 20 kilometers
from the compact car-sized rover's current resting place.
