Title:
Sand Dunes on Mars
Explanation:
Sand dunes on Mars can appear exotic. The dark dunes above [ http://www.msss.com…] might be compared to shark's teeth [ http://mgs.dnr.md.g…] or chocolate confections [ http://www.explorat…]. In reality, they arise from the complex relationship between the sandy surface [ http://antwrp.gsfc.…] and high winds [ http://antwrp.gsfc.…] on Mars. These particular dunes [ http://antwrp.gsfc.…] are located in Proctor Crater [ http://www.msss.com…], a 170 kilometer wide crater first seen to house sand dunes by Mariner 9 [ http://nssdc.gsfc.n…] more than 25 years ago. The above picture [ http://www.msss.com…] was taken by Mars Global Surveyor [ http://mars.jpl.nas…] (MGS), a robot spacecraft [ http://mars.jpl.nas…] currently in orbit around Mars [ http://www.nineplan…]. MGS has recently completed a primary goal [ http://www.msss.com…] of taking and transmitting detailed survey images of the red planet [ http://antwrp.gsfc.…] over an entire Martian year (669 Earth days). MGS will now be deployed [ http://www.space.co…] to study particularly interesting regions of Mars [ http://cmex-www.arc…] in more detail.
