##Welcome to r/hirise!

A subreddit dedicated to the most awesome camera ever launched into space, best viewed in the new reddit desktop!

The High Resolution Imaging Science Experiment (HiRISE) is a high-quality photographic instrument mounted onto the Mars Reconnaissance Orbiter spacecraft, launched by NASA in August 2005 and arriving at Mars in March 2006. For the past decade, HiRISE, from the comfort of Low Mars Orbit, has been capturing the many wonderful sights of our alien neighbor in unprecedented high resolution. This subreddit is dedicated to sharing those images in all their glory!

This subreddit is not officially run by, and has no affiliation with, the HiRISE team, the University of Arizona, NASA, or the Jet Propulsion Laboratory.

Old reddit theme is r/click by u/postpics. Current background on old reddit is "Layering in Arabia Crater", captured in February 2007.
