Mars: NASA's Curiosity Beams Back a Color 360 of Gale Crater

Hi My Friends: A VUELO DE UN QUINDE EL BLOG., The first images from Curiosity's color Mast Camera (Mastcam) have been received by scientists at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif. The 130 low-resolution thumbnails, which were received Thursday morning, provide scientists and engineers of NASA's newest Mars rover their first color, horizon-to-horizon glimpse of Gale Crater.

 Gale Crater Vista, in Glorious Color
 This is the first 360-degree panorama in color of the Gale Crater landing site taken by NASA's Curiosity rover. The panorama was made from thumbnail versions of images taken by the Mast Camera.

Scientists will be taking a closer look at several splotches in the foreground that appear gray. These areas show the effects of the descent stage's rocket engines blasting the ground. What appeared as a dark strip of dunes in previous, black-and-white pictures from Curiosity can also be seen along the top of this mosaic, but the color images also reveal additional shades of reddish brown around the dunes, likely indicating different textures or materials.

The images were taken late Aug. 8 PDT (Aug. 9 EDT) by the 34-millimeter Mast Camera. This panorama mosaic was made of 130 images of 144 by 144 pixels each. Selected full frames from this panorama, which are 1,200 by 1,200 pixels each, are expected to be transmitted to Earth later. The images in this panorama were brightened in the processing. Mars only receives half the sunlight Earth does and this image was taken in the late Martian afternoon.

 NASA's Curiosity Beams Back a Color 360 of Gale Crater
PASADENA, Calif. -- The first images from Curiosity's color Mast Camera (Mastcam) have been received by scientists at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif. The 130 low-resolution thumbnails, which were received Thursday morning, provide scientists and engineers of NASA's newest Mars rover their first color, horizon-to-horizon glimpse of Gale Crater.

"After a year in cold storage, where it endured the rigors of launch, the deep space cruise to Mars and everything that went on during landing, it is great to see our camera is working as planned," said Mike Malin, principal investigator of the Mastcam instrument from Malin Space Science Systems in San Diego. "As engaging as this color panorama is, it is important to note this is only one-eighth the potential resolution of images from this camera."

The Curiosity team also continued to downlink high-resolution black-and-white images from its Navigation Camera (Navcam). These individual images have been stitched together to provide a high-resolution Navcam panorama, including a glimpse of the rover's deck. Evident on some portions of the deck are some small Martian pebbles.

"The latest Navcam images show us the rocket engines on our descent stage kicked up some material from the surface of Mars, several pieces which ended up on our rover's deck," said Mike Watkins, mission manager for Curiosity from JPL. "These small pebbles we currently see are up to about 0.4 inches [one centimeter] in size and should pose no problems for mission operations. It will be interesting to see how long our hitchhikers stick around."

Mission engineers devoted part of their third Martian day, or "Sol 3," to checking the status of four of Curiosity's science instruments after their long trip. The rover's Alpha Particle X-ray Spectrometer, Chemistry and Mineralogy analyzer, Sample Analysis at Mars and Dynamic Albedo of Neutrons instruments were each energized and went through a preliminary checkout. The team also performed a check on the rover's second flight computer.

Before landing, the mission's science team began the process of creating a geological map of about 150 square miles (390 square kilometers) within Gale Crater, including the landing area.

"It is important to understand the geological context around Curiosity," said Dawn Sumner of the University of California, Davis, a member of the Curiosity science team. "We want to choose a route to Mount Sharp that makes good progress toward the destination while allowing important science observations along the way."

The mapping project divided the area into 151 quadrangles of about one square mile (2.6 square kilometers) each. Curiosity landed in the quadrangle called Yellowknife. Yellowknife is the city in northern Canada that was the starting point for many of the great geological expeditions to map the oldest rocks in North America.

Curiosity carries 10 science instruments with a total mass 15 times as large as the science payloads on NASA's Mars Exploration 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.

The Mars Reconnaissance Orbiter and Mars Exploration Rover projects are managed by JPL for NASA's Science Mission Directorate at Headquarters in 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.
