NASA Believes Seasonal Flows On Mars Are Caused by Seeping Water
What is RSL? On planet Mars, some extraordinary flows can be seen; these active flows are called “recurring slope lineae,” or RSL. The central peaks of Hale Crater host one of the most active site of the Red planet.
The phenomenon of active flows is already under scientific study but a new image taken from the Mars Reconnaissance Orbiter is supposed to give a new fresher insight about the active flows. This image was captured in the middle summer when RSL are considered in full flow in the southern mid latitudes.
The image shows that redness of this RSL, in Hale, is much intense than most of the others. This “reddish” surface of RSL is probably due to oxidized iron compounds. In the image, the RSL can be seen extending downhill from the clips.
“The Hale RSL are also unusual because they began activity much earlier than most RSL sites in the middle southern latitudes, and were well-developed in the early spring (see ESP_038073_1440),” notes NASA.
Seeping water is considered as the factor which produces recurring slope lineae. If seeping water is producing RSL in case of Hale Carter also, then it must be “rich in salts to lower its freezing point significantly below the freezing point of pure water,” NASA observes.
NASA used Orbiter’s HiRISE camera to capture the image of RSL. Even minute details are successfully taken through the powerful telescopic lens of HiRISE.
MARS has been in the news lately. The most interesting one was about its color. Though we are calling it a Red Planet, there was a debate on whether Mars is red or blue. By same token, some evidences hint presence of huge quantity of water on Mars.
