A June 2012 revision of the landing target area for
Curiosity, the big rover of NASA's Mars Science Laboratory mission, reduces the
area's size. It also puts the center of the landing area closer to Mount Sharp,
which bears geological layers that are the mission's prime destination.
The larger ellipse in this image, about 12.4 miles (20
kilometers) by 15.5 miles (25 kilometers) shows what the target area was prior
to revision. The smaller one, about 12 miles by 4 miles (20 by 7 kilometers),
indicates the revised target area.
This oblique view of Mount Sharp is derived from a
combination of elevation and imaging data from three Mars orbiters. The view is
looking toward the southeast. Gale Crater is 96 miles (154 kilometers) in
diameter. Mount Sharp rises about 3.4 miles (5.5 kilometers) above the floor of
Gale Crater. Stratification on Mount Sharp suggests the mountain is a surviving
remnant of an extensive series of deposits that were laid down after a massive
impact that excavated Gale Crater more than 3 billion years ago. The layers offer
a history book of sequential chapters recording environmental conditions when
each stratum was deposited.
Landing will be about 10:31 p.m. on Aug. 5, 2012,
Pacific Daylight (early Aug. 6 Universal Time and EasternTime). During a prime
mission lasting nearly two years after landing, Curiosity will use 10
instruments to investigate whether this area of Mars has ever offered
conditions favorable for life, including the chemical ingredients for life.
The image combines elevation data from the High Resolution
Stereo Camera on the European Space Agency's Mars Express orbiter, image data
from the Context Camera on NASA's Mars Reconnaissance Orbiter, and color
information from Viking Orbiter imagery. There is no vertical exaggeration in
the image.
