NASA shares images of icy Mars crater captured over a period of 6 years

latest pictures released by National Aeronautics ncy (NASA) show how an icy Mars crater has changed over a period of six Martian years. ims released by NASA were captured by HiRISE camera which is onboard Mars Reconnaissance Orbiter (MRO). An impact crater on rth polar cap can be seen in ims, which contain an icy deposit on crater floor.

Icy Mars crater ims

NMRO has been observing Mars for 6 Martian Years (MY), each of which lasts for 687 Earth days. "Shown here is an impact crater on rth polar ice cap, which contains an icy deposit on crater floor. se inter-crater ice deposits shrink and expand or change shape or surface texture from year to year," said Alfred McEwen, principal investigator for HiRISE.  In this animation, we can see appearance of this crater fill in Martian Year February 2008, August 2010, July 2012, February 2016, January 2018, and December 2019.

University of Arizona, Tucson, operates HiRISE, which was built by Ball Aero & Techlogies Corp., Boulder, Coloro. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasena, California, mans Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington. As NASA is planning to launch a manned mission in future it makes more interesting for scientists to dig deeper.

NASA's Mars Reconnaissance Orbiter (MRO) has worked more than double its planned mission life since launch in 2005. According to NASA's official web p, ncy is planning to keep using it past mid-2020s. Increased reliance on a star tracker, and less on aging gyroscopes, is one way mission is apting to extend its longevity. Ar step is wringing a more useful life from batteries. mission's extended service provides data relay from assets on Mars' surface and observations with its science instruments, despite some degration in capabilities.
