A Mars mosaic from Curiosity using its close-up camera
During the three-plus months in the summer when Curiosity stayed at one location for its most recent drilling campaign, the science team used its ChemCam Remote Micro-Imager camera (RMI), originally designed to take very close-up photos, to create a 216 photo mosaic of the long distance horizon. They have now released that mosaic, which you can see as a video at the link. The mosaic itself is a very long strip, which is best viewed up close and scrolling across it, as the video does. As the scientists note,
During Curiosity’s first year on Mars, it was recognized that, thanks to its powerful optics, RMI could also go from a microscope to a telescope and play a significant role as a long-distance reconnaissance tool. It gives a typical circular “spyglass” black and white picture of a small region. So RMI complements other cameras quite nicely, thanks to its very long focal length. When stitched together, RMI mosaics reveal details of the landscape several kilometers from the rover, and provides pictures that are very complementary to orbital observations, giving a more human-like, ground-based perspective.
From July to October of 2020, Curiosity stayed parked at the same place to perform various rock sampling analyses. This rare opportunity of staying at the same location for a long time was used by the team to target very distant areas of interest, building an ever-growing RMI mosaic between September 9 and October 23 (sols 2878 and 2921) that eventually became 216 overlapping images. When stitched into a 46947×7260 pixel panorama, it covers over 50 degrees of azimuth along the horizon, from the bottom layers of “Mount Sharp” on the right to the edge of “Vera Rubin Ridge” on the left.
The camera’s resolution is so good that it was able in the mosaic to resolve large boulders on the crater wall of Gale Crater almost 37 miles away.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Wow. Coolest thing I’ve seen this week. Fantastic stuff; almost like being on the surface yourself. A little depressing to think the whole planet looks more-or-less like this: no biology. Also noticed that the panorama was taken over about six weeks, and no evidence of weather. Geologically fascinating, but kind of boring. The more images I see of Mars from ground-level, the more it looks like a great place to visit, but maybe not live there.
