With my month off technology and my Grand Marais adventure posts, it has been quite some time since I checked in with the progress of the Mars rover, Curiosity. Given that it was so cold and snowy yesterday, I did not get out to exercise. Just could not do it. So today, I checked in with the website http://mars.jpl.nasa.gov/msl/multimedia/images/?s=1.
The above photo shows a view from NASA's Mars Reconnaissance Orbiter taken on April 8, 2015, catches
sight of NASA's Curiosity Mars rover passing through a valley called
"Artist's Drive" on the lower slope of Mount Sharp. It shows the rover's position after a drive of about 75 feet (23
meters) during the 949th Martian day, or sol, of the rover's work on
Mars. North is toward the top. The rover's location, with its
shadow extending toward the right, is indicated with an inscribed
rectangle. The view in this image covers an area about 550 yards (500
meters) across.
A green star in the above photo marks the location of NASA's Curiosity Mars rover after a
drive on the mission's 957th Martian day, or sol, (April 16, 2015). The
map covers an area about 1.25 miles (2 kilometers) wide.
Curiosity
landed on Mars in August 2012. The drive on Sol 957 brought the
mission's total driving distance past the 10-kilometer mark (6.214
miles). The rover is passing through a series of shallow valleys on a
path from the "Pahrump Hills" outcrop, which it investigated for six
months, toward its next science destination, called "Logan Pass."
NASA's Curiosity Mars rover used its Navigation Camera (Navcam) to
capture this view on April 11, 2015, during the 952nd Martian day, or
sol of the rover's work on Mars. The rover's location was in a valley
called "Artist's Drive" on the route up Mount Sharp. The view spans from east, at left, to southwest, at right. Upper Mount Sharp appears on the horizon at left.
This view from the Mars Hand Lens Imager (MAHLI) on the arm of NASA's
Curiosity Mars rover is a close-up of a two-tone mineral vein at a site
called "Garden City" on lower Mount Sharp. The area shown is
roughly one inch (2.5 centimeters) wide. The image was taken at night,
using illumination from MAHLI's light-emitting diodes, during the 935th
Martian day, or sol, of Curiosity's work on Mars (March 25, 2015).
The
vein includes both light-toned and dark-toned materials. The whiter
material appears to have ripped up and incorporated portions of both the
darker vein material (black arrows) in and a third material (white arrow ).
The Curiosity mission's examination of material in these veins may
provide clues about multiple episodes of fluids moving through fractured
rock at this site. The fluid movement through fractures occurred later
than wet environmental conditions in which the host rock formed, before
it hardened and cracked.
This view from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover
shows a network of two-tone mineral veins at an area called "Garden
City" on lower Mount Sharp.
The veins combine light and dark
material. The veins at this site jut to heights of up to about 2.5
inches (6 centimeters) above the surrounding rock, and their widths
range up to about 1.5 inches (4 centimeters). Figure 1 includes a
30-centimeter scale bar (about 12 inches).
Mineral
veins such as these form where fluids move through fractured rocks,
depositing minerals in the fractures and affecting chemistry of the
surrounding rock. In this case, the veins have been more resistant to
erosion than the surrounding host rock.
This self-portrait of NASA's Curiosity Mars rover shows the vehicle at
the "Mojave" site, where its drill collected the mission's second taste
of Mount Sharp.
The scene combines dozens of images taken during
January 2015 by the Mars Hand Lens Imager (MAHLI) camera at the end of
the rover's robotic arm. The pale "Pahrump Hills" outcrop surrounds the
rover, and the upper portion of Mount Sharp is visible on the horizon.
Darker ground at upper right and lower left holds ripples of wind-blown
sand and dust.
This chart illustrates comparisons among the distances driven by various
wheeled vehicles on the surface of Earth's moon and Mars. Of the
vehicles shown, the NASA Mars rovers Opportunity and Curiosity are still
active and the totals for those two are distances driven as of March
24, 2015.
Opportunity completed its first Mars marathon March
24, 2015 - 26.219 miles (42.195 kilometers) - with a finish time of
roughly 11 years and two months.
