Cool image time! The panorama above was created from three photos downloaded today from Curiosity’s right navigation camera. It looks to the northeast of the rover, out across Gale Crater. The crater floor is about 1,750 feet lower.

This is dust season on Mars, which explains the thick haze in the crater. About 25 miles away the crater rim can be faintly seen through the dust haze as a mountain chain. If you look at the full resolution panorama you can see several buttes on the crater floor barely visible through that haze.

The map to the right gives the context. Curiosity’s present location is indicated by the yellow dot, with the yellow lines indicating the area covered by the panorama. The red dotted line indicates the rover’s future planned route.

For the last few weeks Curiosity has been working nestled to the base of a small butte the science team has dubbed “The Prow”, studying its numerous thin layers. I featured the Prow in this January 11th post, though at the time I overestimated its size, which is only about ten feet high. The butte is especially fascinating in that its top layers overhang outward in an unbelievable manner.

The rover is now about to move on, though where must still be decided by the science team. Based on their most recent update it appears they are not ready to leave this barren rocky hollow surrounded with many-layered buttes, and will take the rover to another.

Cool image time! Curiosity yesterday used its navigation cameras to take a panorama of the view inside Maria Gordon Notch. The mosaic above, created from five images taken by the right navigation camera, shows the view looking south and uphill towards Mount Sharp. The heights of the nearest four hills are likely ranging from 30 to 100 feet.

The red dotted line indicates the planned route out of Gordon Notch and up onto the Greenheugh Pediment. If you click on the panorama to look at the full resolution version, you will see that the exit route looks extemely rough, possibly too rough for Curiosity to handle. How the science team handles this issue will be fascinating to watch in the coming weeks.

The map to the right gives us an overview. The white line is Curiosity’s actual travels. The red dotted line marks the planned route. The yellow lines indicate the area covered by the panorama above.

The most striking feature of this Martian terrain is its stark barrenness. All one can see in all directions are rocks and inanimate geology. There is no life, none at all. On Earth it is practically impossible to find any mountainous spot as barren as this, even in the most extreme and hostile environments.

As I’ve said before, Mars is strange, Mars is wonderful, and above all, Mars is alien.

Cool image time! The mosaic above was created from four photos taken by Curiosity’s left navigation camera on December 12, 2021, just after the rover had moved into Maria Gordon Notch. The view is to the north, looking back at the rover’s journey climbing up the floor of Gale Crater into the foothills of Mount Sharp. The rim of Gale Crater can be seen about 25 to 30 miles away.

The cliff in shadow on the left is about 40 feet high. The cliff in sunlight on the right is between 30 to 60 feet high, depending on where you measure.

The overview map to the right shows Curiosity’s entire journey, with the yellow lines indicating the approximate area covered by the mosaic above. All told the rover has climbed about 1,700 feet since it landed. While much of the rover’s route is blocked from our view by the cliffs on left, the nearest sand dune sea in the center of the mosaic is the one that the rover circled around from January 2021 to June 2021.

Cool image time! The photo to the right, reduced to post here, was taken on November 5, 2021 by Curiosity’s high resolution camera, and looks forward at its planned route up onto the saddle ahead, where the rover will turn right and climb up into Maria Gordon Notch. (See this October post for a map outlining the rover’s future travels.) I think that cliff face is between 40 to 60 feet high, though this is a very wild guess.

As noted by Abigail Fraeman of JPL on the Curiosity blog on November 3, 2021,

The terrain is beginning to steepen as Curiosity gets close to the end of this region, so even though we’re only a few drives away from our last drill site … we’ve already climbed 25 m higher!

The route ahead looks equally steep, though the ground actually appears less rough, with fewer large jagged boulders that Curiosity must avoid to protect its wheels.

It will likely be at least one to three weeks however before Curiosity gets to that saddle. The science team has begun a drilling campaign at the present location, and this will take time, depending on how many holes they decide to drill.

Cool image time! The photo above, the first of 21 identical images taken by Curiosity’s right navigation camera, taken at intervals of about thirteen seconds on October 31st, was probably snapped as part of an effort to spot a moving dust devil. At the resolution available to my software, I see nothing when I compare all 21 photos.

What I do see is a remarkably alien landscape. In the distance can be seen the mountains that mark the rim of Gale Crater, 30-plus miles away. On the image’s right edge you can see the rising slope heading up to the peak of Mount Sharp about 13,000 feet higher.

In the center are those blobby mesas that make this terrain look so strange. For the past decade Curiosity has been traveling from the floor of the crater on the picture’s far left to circle around that dark sand dune sea to climb up the mountain slopes in the foreground in front of those mesas.

It is now heading to the right, into the mountains that make up Mount Sharp. Such a view of the floor of Gale Crater will thus be for the next few years more difficult to catch, as the mountains themselves will block the view. Assuming the rover survives long enough, it will have to climb much higher before it can get such an expansive view again.

Cool image time! The photo to the right, cropped, reduced, and enhanced to post here, was taken on September 21, 2021 by Curiosity’s high resolution mast camera, and shows the top of that spectacular rock outcrop about 200 feet to the west of where the rover presently sits. The top image, from my September 16, 2021 post, “Curiosity: Into the Mountains!”, indicates the location of the photo with the black rectangle. The red dotted line indicates the rover’s future planned route.

I estimate the whole outcrop is about 100 feet high, which means the cliff section seen in the photo to the right is probably about 30 feet high. It would make a great challenge for any number of rock climbers I know.

What makes this image especially striking are the overhanging rocks at the peak’s top. In the Martian gravity, about one third that of Earth’s, it is possible for much more delicate rock shapes to remain structurally stable, and the sharp jagged boulders hanging out at the top of this cliff demonstrate that in a quite breath-taking way. On Earth such delicate rocks would likely have quickly fallen.

The Curiosity science team is obviously most interested in the massive layers revealed by this cliff. I am also sure they are also as enthralled by the scenery as I am.

Time for another cool image from Curiosity. The photo above was taken by one of the rover’s navigation cameras today, and looks south in the direction of Curiosity’s future travels. The red dotted line shows that planned route, along the cliff face to then turn west into what the science team has dubbed Maria Gordon Notch, in honor of a Scottish scientist from the early 20th century.

The map to the right gives the context as seen from above, as well as the planned travels beyond the notch. The white dotted route marks Curiosity’s actual travel route. The red dotted line marks the planned route. The yellow lines the area seen in the above picture.

At present Curiosity is paused as it performs a new drilling campaign about 200 feet from the base of that cliff face, drilling the rover’s 33rd hole on Mars.

The outcrop resembling a ship’s prow on the image’s right, which I still consider the most spectacular rock outcrop seen yet on any planetary mission anywhere, is about 100 feet high.

I hope my readers won’t get tired of seeing these mountain views from Curiosity, but I can’t get enough of them.

The image above is a panorama I’ve created from six photos taken by Curiosity’s right navigation camera yesterday. The box marks the location of that spectacular outcrop I highlighted in the previous mountain view five days ago. The red dotted line shows the rover’s upcoming planned route. The white cross indicates the pavement bedrock where the science team hopes to next drill.

For scale, Navarro Mountain is rises about 400 feet from where the rover presently sits. The peak of Mount Sharp is actually not visible, blocked by its near white flank on the panorama’s left edge. That peak is still 13,000 feet higher up from where the rover presently sits.

The rise of rocks next to the words “entering Gediz Vallis” is actually only probably five to ten feet high, as it is very close to the rover.

Curiosity’s travels continue to get more and more exciting to follow.
