The European Space Agency (ESA) has released a hauntingly beautiful image of the surface of Mars, showing how the landscape there is sculpted by winds.<\/p>\n
The image, taken from orbit by the ESA and Roscosmos ExoMars Trace Gas Orbiter (TGO), shows the Hooke Crater area in the southern highlands of Mars. The false colors are due to the filters used by TGO\u2019s CaSSIS camera, which looks in the infrared wavelength to capture more details of the surface mineralogy.<\/p>\n This unusual-looking scenery is par for the course on Mars, where the thin atmosphere, high winds, and large amounts of dust combine to create striking features on the surface.<\/p>\n \u201cThis type of scenery is similar to \u2018chaotic terrain\u2019: A kind of broken, disrupted terrain seen across Mars where haphazard groups of variously sized and shaped rocks \u2014 irregular knobs, conical mounds, ridges, flat-topped hills known as mesas \u2014 clump together, often enclosed within depressions,\u201d the European Space Agency explains<\/a>. \u201cThere are around 30 regions of chaotic terrain defined on Mars (see ESA Mars Express views of Ariadnes Colles<\/a>, Pyrrhae Regio<\/a>, and Iani Chaos<\/a> for just a small sample); while this small patch has not been defined as one of these, its appearance is certainly chaotic.\u201d<\/p>\n When seen up close, you can see the blue-tinted tendrils stretching out across the image. These are the tracks of dust devils<\/a>, whirlwinds which are like tiny tornadoes and are common on Mars. When hot air at the surface of the planet rises quickly through cooler air above it, it forms an updraft that can begin to rotate and create a dust devil. This spinning column of air travels across the planet\u2019s surface, leaving the distinctive tracks, before petering out.<\/p>\n ESA notes that the tracks seen in this image appear to travel on a north-south orientation, which could be the result of local winds blowing in that direction. Learning more about the <artian weather, including its winds, is the major focus of one of the instruments aboard NASA\u2019s Perseverance rover. The MEDA instrument<\/a> collects data on wind speed and direction, temperature, humidity, and the amount of dust in the atmosphere in order to better understand the martian weather system.<\/p>\n![\"A](\"https:\/\/icdn.digitaltrends.com\/image\/digitaltrends\/webp-net-resizeimage-14-720x720.jpg\")
