- (A) Curiosity will trundle around its landing site looking for interesting rock features to study. Its top speed is about 4cm/s
- (B) This mission has 17 cameras. They will identify particular targets, and a laser will zap those rocks to probe their chemistry
- (C) If the signal is significant, Curiosity will swing over instruments on its arm for close-up investigation. These include a microscope
- (D) Samples drilled from rock, or scooped from the soil, can be delivered to two hi-tech analysis labs inside the rover body
- (E) The results are sent to Earth through antennas on the rover deck. Return commands tell the rover where it should drive next
"Curiosity's landing site is beginning to come into focus," said John Grotzinger, project manager of NASA's Mars Science Laboratory mission, at the California Institute of Technology in Pasadena. "In the image, we are looking to the northwest. What you see on the horizon is the rim of Gale Crater. In the foreground, you can see a gravel field. The question is, where does this gravel come from? It is the first of what will be many scientific questions to come from our new home on Mars."
While the image is twice as big in pixel size as the first images beamed down from the rover, they are only half the size of full-resolution Hazcam images. During future mission operations, these images will be used by the mission's navigators and rover drivers to help plan the vehicle's next drive. Other cameras aboard Curiosity, with color capability and much higher resolution, are expected to be sent back to Earth over the next several days.

A mosaic of high-definition images of Mount Sharp, the central peak dominating the landing site at Gale Crater, reveals tilted strata never before seen on Mars. The strata dip downwards at an angle close to that of the slope of the foothills of the 18,000-ft. tall mountain within which they are formed.
“The cool thing is the cameras have discovered something we were unaware of,” says mission chief scientist John Grotzinger. “This thing jumped out at us as being very different to what we expected,” he adds. Lying in the low-lying foothills beyond the dune field between the rover and the base of Mount Sharp, the inclined layers are a “spectacular feature” that could not be seen from orbit.
NASA is not yet willing to speculate in detail on the mechanics of the processes which created the landform. On earth such features are typically formed by tectonic, volcanic, sub-aqueous or wind-driven processes. The JPL team plans to use Curiosity’s stereoscopic mast cameras (Mastcam) to measure the precise angle of the dipping strata after a short 10-meter drive scheduled for Aug. 28, says Grotzinger. The new images were collected by the rover’s 100-millimeter telephoto lens and 34mm wide-angle lens.
According to the Curiosity Rover, Mars reached a maximum temperature of -29 C on Tuesday, a temperature Winnipeg only reached shortly before 3 p.m.
The deep freeze over much of Southern Manitoba prompted extreme wind chill warnings in the area and most of the north.
In Winnipeg, the daytime high temperature for Tuesday was only expected to reach –31 C, but the windchill made it feel more like –40 to –50. That means exposed skin can freeze in less than five minutes.
On Monday, it got as warm as –28 C.
In the northern half of the province, in places like Thompson, Nelson House, Lynn Lake, Leaf Rapids and Churchill, the wind chills on Tuesday made it feel like –48 to –53.
The entire province was under an extreme wind chill warning on Monday, but it was later lifted in the central portion of Manitoba as well as the southwest and southeast corners.
