Remember the time when NASA’s Curiosity Rover discovered signs of an entire lake and stream systems on Mars?
Those exciting finds finally proved the long postulated theory that ancient Mars in its late formative years might have supported primitive or even microbial life.
While the presence of water in its liquid state is doubtful today, the HiRISE camera on NASA’s Mars Reconnaissance Orbiter (MRO) has spotted a big gully on the Red Planet that has formed in the space of last three years!
A gully on Mars is a lot similar to all those little river channels that we have on earth.
But officials at NASA have already stated that the newest gully on Mars could well have been formed by frozen carbon dioxide on the planet, rather than a stream of water.
Winters on the Red Planet can be particularly chilly and the high CO2 content of the planet might have turned liquid and shaped the new gully.
Since the two images from the HiRISE camera were capture good three years apart, there is no way of accurately predicting the season in which the gully was formed. Photographed on May 25, 2013 by MRO, the fresh gully sits on the crater wall located in mid-southern latitudes of the planet.
For those looking for signs of water on the planet, the search might be still on, but the discovery gives us a glimpse the general activity on the planet during its harsh winters and maybe even an insight into its past and the elements the shaped its present topography.
