The High Resolution Imaging Science Experiment aboard NASA’s Mars Reconnaissance Orbiter, has returned more than 8,214 gigapixel-size images of the Martian surface since the start of the science phase of the mission in November 2006.
HiRISE scientists released 1,005 observations of Mars made between April 26 and July 21 to NASA’s mission data archive, called the Planetary Data System, and also to the public last week.

UNIVERSITY OF ARIZONA PRESS RELEASE
Scientists on the HiRISE team have discovered never-before-seen impact “megabreccia” and a possibly once-habitable ancient lake on Mars at a place called Holden crater.
The megabreccia is topped by layers of fine sediments that formed in what apparently was a long-lived, calm lake that filled Holden crater on early Mars, HiRISE scientists say.
“Holden crater has some of the best-exposed lake deposits and ancient megabreccia known on Mars,” said HiRISE’s principal investigator, professor Alfred McEwen of the UA’s Lunar and Planetary Laboratory. ”Both contain minerals that formed in the presence of water and mark potentially habitable environments. This would be an excellent place to send a rover or sample-return mission to make major advances in understanding if Mars supported life.“

NASA Press Release
Pasadena, Calif. — A NASA spacecraft in orbit around Mars has taken the first ever image of active avalanches near the Red Planet’s north pole. The image shows tan clouds billowing away from the foot of a towering slope, where ice and dust have just cascaded down.
The High Resolution Imaging Science Experiment (HiRISE) on NASA’s Mars Reconnaissance Orbiter took the photograph Feb. 19. It is one of approximately 2,400 HiRISE images being released today.
