MARS is universally often known as the Purple Planet, however a shocking launched by US house company NASA has revealed the complexities of its color palette.
The placing picture was captured by NASA’s Mars Reconnaissance Orbiter’s (MRO) digital camera, which is managed by the College of Arizona, on January 24 and launched this week whereas the planet stays within the grip of a large sand storm.
The storm has silenced NASA’s solar-powered Alternative rover however its better-known Curiosity rover has not been affected, persevering with to gather information and even posing for a dusty selfie.
The dune was noticed on Mars’ Lyot Crater area and researchers suspect it could be product of “finer materials” than neighbouring dunes, based on a press release from the house company.

The smaller dunes are traditional barchan dunes — the technical time period for a crescent-shaped dune fashioned by gusts of wind.
The large blue one, nonetheless, “showing like turquoise blue in enhanced color, is product of finer materials and/or has a distinct composition than the encompassing,” NASA stated.
Planetary Geologist Alfred McEwen, one of many scientists who operates the College of Arizona’s Excessive Decision Imaging Science Experiment (HiRISE) digital camera that took the , defined the way it got here to be.
“The photographs are given min-max stretches in every particular person color picture to extend distinction,” Dr McEwen advised science website Inverse.
“The dunes are literally gray, however seem comparatively blue after such a stretch as a result of most of Mars is pink.”
MRO, which blasted into house in 2005, is learning the historical past of water on Mars.
Curiosity rover has beforehand proven that the planet is house to sand dunes the dimensions of soccer fields, in addition to small sand ripples.
