This photo from the High Resolution Imaging Science Experiment ( HiRISE ) photographic camera on NASA ’s Mars Reconnaissance Orbiter shows a fresh volcanic crater about 100 feet ( 30 metre ) in diameter at the center . The shock happened somewhen between July 2010 and May 2012 . look at the map - protrude version of the image here :
The enhanced colors unveil a large , rayed blow zone and far - fling ejecta , point a massive explosion throw junk as far as 15 kilometers in aloofness :
free-base on evident change between earlier low-toned - re images , investigator used HiRISE to acquire this new image on Nov. 19 , 2013 .
Meteorites keep make Mars more than 200 times per year , but few new crater pack as much visual punch as one seen in a NASA image released today .
AsNASA explains :
Because the terrain where the crater formed is dusty , the fresh crater appears blue in the enhanced color of the figure of speech , due to removal of the reddish rubble in that surface area . Debris thresh about outwards during the formation of the crater is called ejecta . In examining ejecta ’s distribution , scientist can learn more about the impact issue . The explosion that excavate this volcanic crater threw ejecta as far as 9.3 miles ( 15 kilometers ) .
The crater is at 3.7 degree north latitude , 53.4 degree east longitude on Mars . Before - and - after imaging that bracket show date of reinvigorated craters on Mars has bespeak that impacts producing craters at least 12.8 feet ( 3.9 meters ) in diam occur at a rate transcend 200 per year globally . Few of the scars are as striking in appearance as this one .
