Mars Curiosity has found an ancient River
NASA’s Curiosity rover found evidence for an ancient, flowing stream on Mars at a few sites, including the rock outcrop pictured here, which the science team has named “Hottah” after Hottah Lake in Canada’s Northwest Territories. Credit: NASA/JPL/Caltech
At a press briefing, members of the Mars Science Laboratory team said:
“Too many things that point away from a single burst event, I’m comfortable to argue that it is beyond the 1,000 year timescales, even though this is very early on in our findings.”The Link outcrop was imaged with the 100-millimeter Mast Camera on Sept. 2, 2012, which was the 27th sol, or Martian day of operations.The name Link is derived from a significant rock formation in the Northwest Territories of Canada, where there is also a lake with the same name.Scientists enhanced the color in this version to show the Martian scene as it would appear under the lighting conditions we have on Earth, which helps in analyzing the terrain.
This image shows the topography, with shading added, around the area where NASA’s Curiosity rover landed on Aug. 5 PDT (Aug. 6 EDT). Higher elevations are colored in red, with cooler colors indicating transitions downslope to lower elevations. The black oval indicates the targeted landing area for the rover known as the “landing ellipse,” and the cross shows where the rover actually landed. Image credit: NASA/JPL-Caltech/UofA
