PASADENA, Calif. -- Remarkable image
sets from NASA's Curiosity rover and Mars Reconnaissance Orbiter (MRO) are
continuing to develop the story of Curiosity's landing and first days on Mars.
The images from Curiosity's
just-activated navigation cameras, or Navcams, include the rover's first
self-portrait, looking down at its deck from above. Another Navcam image set,
in lower-resolution thumbnails, is the first 360-degree view of Curiosity's new
home in Gale Crater. Also downlinked were two, higher-resolution Navcams
providing the most detailed depiction to date of the surface adjacent to the
rover.
"These Navcam images indicate that
our powered descent stage did more than give us a great ride, it gave our
science team an amazing freebie," said John Grotzinger, project scientist
for the mission from the California Institute of Technology in Pasadena.
"The thrust from the rockets actually dug a one-and-a-half-foot-long [0.5
meter] trench in the surface. It appears we can see Martian bedrock on the
bottom. Its depth below the surface is valuable data we can use going
forward."
Another image set, courtesy of the
Context Camera, or CTX, aboard NASA's MRO has pinpointed the final resting
spots of the six, 55-pound (25-kilogram) entry ballast masses. The tungsten
masses impacted the Martian surface at a high speed about 7.5 miles (12
kilometers) from Curiosity's landing location.
Curiosity's latest images are available
at http://1.usa.gov/MfiyD0.
Wednesday, the team deployed the 3.6
foot-tall (1.1-meter) camera mast, activated and gathered surface radiation
data from the rover's Radiation Assessment Detector and concluded testing of
the rover's high-gain antenna.
Curiosity carries 10 science instruments
with a total mass 15 times as large as the science payloads on NASA's Mars
rovers Spirit and Opportunity. Some of the tools, such as a laser-firing
instrument for checking rocks' elemental composition from a distance, are the
first of their kind on Mars. Curiosity will use a drill and scoop, which are
located at the end of its robotic arm, to gather soil and powdered samples of
rock interiors, then sieve and parcel out these samples into the rover's
analytical laboratory instruments.
To handle this science toolkit,
Curiosity is twice as long and five times as heavy as Spirit or Opportunity.
The Gale Crater landing site places the rover within driving distance of layers
of the crater's interior mountain. Observations from orbit have identified clay
and sulfate minerals in the lower layers, indicating a wet history.
MRO's High Resolution Imaging Science
Experiment (HiRISE) camera is operated by the University of Arizona in Tucson.
The instrument was built by Ball Aerospace & Technologies Corp. in Boulder,
Colo. The Mars Reconnaissance Orbiter and Mars Exploration Rover projects are
managed by JPL for NASA's Science Mission Directorate, Washington. The rover
was designed, developed and assembled at JPL. JPL is a division of the
California Institute of Technology in Pasadena. Lockheed Martin Space Systems
in Denver built the orbiter.
