The Mountains of Mars
Click for full resolution. The highest mountain on the right is about 450 feet high.
Even as the rover Perseverance is beginning its first science campaign on the floor of Jezero Crater, the rover Curiosity about 3,000 miles to the east has begun its climb into the mountains of Mars that surround the central peak of Gale Crater, Mount Sharp.
The mosaic above, made from two images taken by the rover’s right navigation camera (here and here), shows what Curiosity sees ahead. Since my last update on June 4th describing Curiosity’s future travels, the rover’s science team has pushed forward directly uphill towards the entrance to the canyon Gediz Vallis, visible as the gap between the mountains to the right and left in the above mosaic.
The overview map below shows the rover’s approximate present position, with the yellow lines indicating what the above photo is looking at.

The dotted red line marks the original route the scientists had planned. It right now appears that instead of heading around the high mountains to the west to enter Gediz Vallis farther south, they are heading directly into the canyon. Though they will likely simply dip the rover’s toe into the canyon, then back off and circle around as planned, this is not guaranteed. The rover’s wheels are not in great shape, and the terrain they are traversing is quite rough. They may have decided it is more important to climb as high as they can as quickly as they can, to get to the sulfate unit of rocks indicated by the brightest tan layers on the overview map.
If they do as I am guessing, they will push into the canyon a short distance, then skirt very close to the base of the high butte forming the canyon’s western wall as they head back to their planned route. This will give them excellent terrain to study the sulfate unit as soon as possible, while also affording them (and us!) some breath-taking views of the biggest Martian mountains ever viewed from ground-level.
I intend to post those images, as they occur, so stay tuned. The best part of Curiosity’s Martian journey is now beginning.
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
