Curiosity Mars Rover Snaps 1.8 Billion-Pixel Panorama (narrated video)
NASA Jet Propulsion Laboratory Mar 4, 2020 – 3:09 NASA Curiosity Project Scientist Ashwin Vasavada guides this tour of the rover’s view of the Martian surface.
This panorama showcases “Glen Torridon,” a region on the side of Mount Sharp that Curiosity is exploring. The panorama was taken between Nov. 24 and Dec. 1, 2019, when the Curiosity team was out for the Thanksgiving holiday. Since the rover would be sitting still with few other tasks to do while it waited for the team to return and provide its next commands, the rover had a rare chance to image its surroundings several days in a row without moving.
Composed of more than 1,000 images and carefully assembled over the ensuing months, the larger version of this composite contains nearly 1.8 billion pixels of Martian landscape.
