NASA Spots New Gully on Mars

One of NASA’s spacecraft has spotted a large gully on planet Mars, and it seems to be a feature which has only appears to have been formed within the past three years. The very strong HiRISE camera which is located on the Mars Reconnaissance Orbiter, or MRO, took an image of the channel, which was discovered on the sloping wall of a crater around the Red Planet’s middle to southern latitudes, back on May 25, 2013. The feature had not been seen in HiRISE photographs that had been taken of the region on Nov. 5, 2010. NASA revealed the Martian image on Wednesday afternoon.

Even though the gully on Mars appears to look very similar to what Earth river channels appear like, it most likely was not made by any type of rolling water, explained NASA representatives. The dates when the gully images were taken are over an entire Martian year, so the observations were not able to identify the specific Martian season of the activity at this site, NASA officials had written down in a narrative about the gully photograph also on Wednesday.

However the representatives added that the before-and-after HiRISE pairs of activity at numerous other sites show that this kind of Martian activity usually happens in the wintertime, at temperatures that are so frigid that carbon dioxide, instead of water, is most likely to play the leading role in creating the gully creation.

Yet, MRO has taken note of other Red Planet topographies that do appear to be related to liquid water. They are dark lines which are called recurring slope lineage. These RSL lines move down the walls of craters and also other slopes when there is warmer weather on Mars, and several scientists believe that they have been produced by salty water which has an iron centered type of antifreeze. However, direct evidence of there actually being water that flows at such RSL sites, is still obscure.

If there is any water flowing over the exterior of the Red Planet in today’s era from time to time, Mars would then be a much more likely place to be hosting life as individuals on Earth know it. That is because here on this planet, life has been found just about any place that there is liquid water. However ancient Mars would have been much more welcoming to any kind of life. One example is NASA’s Curiosity rover found a prehistoric stream and lake system which was very close to its Red Planet landing site. It is believed that spot might have sustained microbial life billions of years in the past.
