Cool image time! The panorama above was created by me using three pictures taken today (here, here, and here) by the right navigation camera on the Mars rover Perseverance. The top of the rover can be seen to the right, as well as its tracks.

The overview map to the right provides the context. The blue dot marks Perseverance’s present position. The white dotted line its past travel route, with the red dotted line indicating the planned route. The yellow lines indicate the approximate area covered by the panorama.

Though the planned route had the rover head west and then south, the rover team instead had the rover retreat eastward about 450 feet the past few days, where it sits now. At the previous western location the team had attempted to find a location to drill a sample core, but apparently the ground was not satisfactory. By retreating to this previous location it could be they think they will have better luck.

What strikes me about this hilly terrain just outside Jezero Crater is its barrenness. You would have great difficulty anywhere on Earth finding terrain so empty of life. On Mars however there is nothing but dirt and rocks, for as far as the eye can see.

A 360 degree view from Perseverance

Andrew Bodrov from Mars360 has created another 360 degree mosaic using 854 high resolution images taken by the rover Perseverance when it stood at Lookout Hill, at the top of the rim of Jezero Crater. I have embedded it below. From his announcement:

The panorama provides a complete view of Perseverance, allowing you to examine its intricate design in incredible detail. Every component is visible, showcasing the engineering brilliance that powers this groundbreaking mission.

The Martian terrain stretches out around the rover, with its tracks cutting a path into the distance. The Jezero Crater rim, visible on the horizon, features rugged rock formations and textured sands that add depth to this remarkable scene.

The overview map to the right provides the context. The view begins by looking south, at the crater rim. If you rotate to the left you will see the tracks of Perseverance, indicating its previous travels, and then the rim to the north. Next the view looks outside the crater to the west.

Perseverance reaches top of Jezero Crater rim

After spending more than three and a half years exploring the floor of Jezero Crater, the rover Perseverance has finally reached the top of the crater’s western rim, and is about to begin exploring the mountainous and potentially rich mining region to the west.

The panorama above, created from two pictures taken by Perseverance’s right navigation camera on December 11, 2024 (here and here), has been cropped, reduced, enhanced, and annotated to post here. It looks west into that mountainous region, with the yellow lines on the overview map to the right indicating the approximate view. The blue dot on that map marks Perseverance’s present position, on top of Lookout Hill, the name the rover team has given to that spot on the rim.

The low resolution of the region beyond the grey strip is unexplained. For some reason the rover team has not yet updated the interactive map showing Perseverance’s travels with the many high resolution pictures that Mars Reconnaissance Orbiter (MRO) has taken of this region, in anticipation of Perseverance’s travels there. I expect however this will change shortly.

Witch Hazel Hill is the first target beyond the rim, where there is an outcrop 330-feet-high with many layers. The rover will then head downhill and south to check out a spot that the scientists believe might show features existing from before Jezero Crater was formed. The rover will then head back up to the rim further south to look at an outcrop of blocks that might actually be ejecta from another much larger Martian impact.

These blocks may represent ancient bedrock broken up during the Isidis impact, a planet-altering event that likely excavated deep into the Martian crust as it created an impact basin some 745 miles (1,200 kilometers) wide, 3.9 billion years in the past.

Jezero sits on the northwestern rim of Isidis.

NASA considering shutting down Curiosity in 2021

Even as the space agency is about to launch a new rover to Mars, it is considering cutting operations for the rover Curiosity as well as considering shutting down its operation as soon as 2021.

Other ongoing missions are threatened by the administration’s fiscal year 2021 budget proposal. “The FY21 budget that the president just recently submitted overall is extremely favorable for the Mars program, but available funding for extended mission longevity is limited,” [said Jim Watzin, director of NASA’s Mars exploration program].

That request would effectively end operations of the Mars Odyssey orbiter, launched in 2001, and reduce the budget for Curiosity from $51.1 million in 2019 to $40 million in 2021, with no funding projected for that rover mission beyond 2021.

The penny-wise-pound-foolish nature of such a decision is breath-taking. Rather than continue, for relatively little cost, running a rover already in place on Mars, the agency will shut it down. And why? So they can initiate other Mars missions costing millions several times more money.

Some of the proposed cuts, such as ending the U.S. funding for Europe’s Mars Express orbiter, make sense. That orbiter has accomplished relatively little, and Europe should be paying for it anyway.

These decisions were announced during a live-stream NASA townhall that was originally to have occurred live at the cancelled Lunar & Planetary Science conference. I suspect its real goal is to garner support for more funding so that the agency will not only get funds for the new missions, it will be able to fund the functioning old ones as well.

Sadly, there would be plenty of money for NASA’s well-run planetary program if our Congress and NASA would stop wasting money on failed projects like Artemis.
