As we close in on Curiosity's 'landiversary' I feel it is a good time to share one of my favourite images from its mission inside Gale crater. This mid-afternoon view from the right-side Mast Camera (R-MastCam) on Curiosity rover features a distant section of the inner rim wall of Gale Crater. It was acquired during a period when there was little dust or haze in the atmosphere, so conditions were good for long-distance imaging. JPL have been studying this particular section of the rim wall throughout the mission comparing the differing lighting conditions. The rover acquired this image during mission sol 1309, April 16, 2016, while the rover was conducting remote science in-between drives on the "Naukluft Plateau" on lower Mount Sharp. The tall peak of the crater wall featured in this image, was located at azimuth 357.2 degrees east of north (or 2.8 degrees from north), is about 17.6 miles (28.4 kilometers) away from the rover at that time. The rim rises about 3,900 feet (1,200 meters) above the base of its foothills. Credits: NASA/JPL-Caltech/MSSS
