Another beautiful view of the foothills of Mount Sharp as seen recently by the Curiosity rover. The rover is continuing to drive closer to these mesas, buttes and canyons. Image processing by James Sorenson. The full-resolution version is available here.
Wind-eroded rocks on Mars can take many different forms, sometimes resembling common earthly objects. Some good new examples include these long, thin slivers of rock which look like “spoons” and “needles,” seen by the Curiosity rover recently on sols 1089 and 1087. These fragile formations are easier to form in Mars’ weaker gravity and thinner atmosphere and can last much longer than they would on Earth – a unique form of Martian “artwork.”
After extensive investigations of rock layers in Marias Pass, a shallow valley near the base of Mount Sharp, the Curiosity rover is now heading southwest again, to continue gradually climbing the lower slopes of the mountain. Marias Pass is a region with rocks and ground which contain high levels of silica and hydrogen, more evidence that there used to be a lot more water here than there is now.
There are a couple new views of the foothills on Mount Sharp from the Curiosity rover, and they are beautiful. Many layers, mesas and buttes are visible, reminiscent of the American southwest. Curiosity will keep getting closer in the weeks and months ahead. Image processing by Lars (@LarsTheWanderer).
NASA’s Curiosity rover has just reached its third anniversary milestone on Mars, after landing in Gale crater on Aug. 5, 2012, and since then has made some incredible science discoveries, with more to come in the months and years ahead. NASA is celebrating this achievement and you can take part, too!
Some great new images of very finely layered rocks near Jocko Butte on sol 976, from Curiosity. The layers tell a geological story of alternating wet conditions in this area on Mars a long time ago. These thin, delicate layers are an amazing sight! All of the raw images from Curiosity can be seen here.
Two new beautiful composite images, from two different rovers and locations on Mars. The first is a sunset in Gale crater, taken by Curiosity. Martian sunsets look bluish due to the light scattering effects of reddish dust in the atmosphere. The other image, from Opportunity, is of the scenic Lindbergh rock mound in the Spirit of St. Louis crater, on the rim of the huge Endeavour crater. A natural monument!
There were some beautiful new images taken of the foothills of Mount Sharp from the Curiosity rover on Mars as it passed through the Artist’s Drive and Logan’s Run valleys. The canyons and mesas on the lower slopes of the mountain keep getting closer!
The search for liquid water on Mars is one that has been on-going for decades. It can’t exist for long on the surface, as it will quickly sublimate into the cold, thin atmosphere. Aquifers deep below the surface are still possible, but there is also another tantalizing possibility which scientists have been considering: brines. Such salty liquid water could theoretically last a bit longer on the surface or in the near-subsurface, and now the Curiosity rover has provided more evidence that this may indeed be happening at its location in Gale Crater, as well as elsewhere.
