As Curiosity has continued to investigate the rock outcrops of Pahrump Hills near the base of Mount Sharp, it has found a variety of interesting textures on the rocks that should provide more clues to the conditions here a long time ago. Shown here are examples of rounded, raised “blisters” and many small elongated “hollows” which look similar to the vugs (where crystals had once formed) seen previously by the Opportunity rover. The hollows were revealed after Curiosity brushed off a layer of dust on the rock.

As the Curiosity rover was approaching the flat rock outcrop called Pahrump Hills, where it is currently drilling again, it spotted a few more interesting features. These include the “ball,” a small round spherical stone, about a cm or two across, which resembles the “blueberry” concretions seen by the Opportunity rover in Meridiani (like the ones in the image at the top of the blog sidebar). The Meridiani ones were all over the place though, while this one seems to be all by itself.
After a long, and at times risky two-year journey, the Mars Science Laboratory rover Curiosity has reached the base of the lower slopes of Mount Sharp, the primary destination since its landing back in 2012. Mount Sharp is about the same height as Mount Rainier on Earth and sits in the middle of the expansive Gale crater. The arrival was announced on Thursday, Sept. 11 at a NASA telecon which discussed Curiosity’s achievements so far and what else now awaits at the mountain.
Some interesting images taken on sol 739 by the Curiosity rover on Mars, at the entrance to Owens Valley. Some of the rocks here were overturned by the rover’s wheels and three of them here have a very speckled appearance with white spots. No word yet on what ChemCam analysis may have shown, but perhaps other geologists have some idea as to what these are?
This photo taken a few days ago by the Curiosity rover has been getting a lot of attention. The object near the centre of the image looks a lot like a femur-type bone! This image was taken on sol 719 of the mission, at the entrance to Hidden Valley where Curiosity is ready to start drilling again at a site just a few feet away called Bonanza King.
Curiosity has come across what appear to be a couple of meteorites in Gale crater. No official word yet, but the consensus seems to be that these are indeed meteorites, and fairly large ones, given their similarity to other confirmed meteorites found previously by both the Spirit and Opportunity rovers. Their shininess indicates that they are likely iron meteorites. It is more common to find meteorites on Mars than on Earth, given the thinner atmosphere and slower erosion rates.
The Curiosity rover has taken another great “selfie” image of itself as it sits parked at Mount Remarkable, the butte where it will soon do some more drilling. This is another beautiful montage by Damia Bouic consisting of many separate images spliced together. Mount Remarkable is just out of view to the left and Mount Sharp is in the distance. The full-size image is here.
The rock outcrops at Mount Remarkable, one of the three main buttes at The Kimberley location where the Curiosity rover is now are a geological bonanza, with a wide variety of rock types and formations. The buttes are surrounded by finely layered rock slabs, and some of the smaller features seen are amazingly delicate-looking, like in these two photos. Original larger images here and here.
