Sols 4362-4363: Plates and Polygons
NASA’s Mars rover Curiosity acquired this image using its Mars Hand Lens Imager (MAHLI) on Nov. 11, 2024 – sol 4360, or Martian day 4,360 of the Mars Science Laboratory Mission – at 00:06:13 UTC. NASA/JPL-Caltech/MSSS Earth planning date: Monday, Nov. 11, 2024
After a successful 23-meter (about 75 feet) drive today in pre-planning we found ourselves in front of some rocks with a curious dark, platy topping. This is similar to material we have seen previously including over the weekend where MAHLI imaged “Buttress Tree.” This beautiful hand-lens image is shown above, where you can see this more resistant platy texture at the top of the layered rock. Unfortunately it was deemed too unsafe to move the arm today, so no contact science observations were made on this dark material, but a plethora of remote science made up for it!
A curious curved fracture along a rock in the workspace became the target of our ChemCam LIBS laser shots called “Pioneer Basin.” ChemCam will then take a long-distance RMI looking back at Gediz Vallis channel, which we have been driving away from. Mastcam is focusing on taking two mosaics of areas of rocks that exhibit light- and dark-toned bands from orbit. We previously drove across these bands in January before we crossed the Gediz Vallis channel. Now that we are over the channel, we are about to drive on the dark, banded material once again. Mastcam is also imaging some interesting polygonal textures we see in a few rocks around the rover. To keep it simple, the science team named all four targets of polygonal rocks “Acrodectes Peak.”
As Curiosity drives further away from the Gediz Vallis channel, the exploration of the sulfate unit continues. Although the driving is tough at times, the beautiful discoveries and amazing geology make the tough times worth it. Let’s hope we can get some contact science activities safe and sound in the next plan.

Sols 4359-4361: The Perfect Road Trip Destination For Any Rover!
NASA’s Mars rover Curiosity acquired this image of its workspace, which includes several targets for investigation — “Buttress Tree,” “Forester Pass,” “Crater Mountain,” “Mahogany Creek,” and “Filly Lake.” Curiosity used its Left Navigation Camera on Nov. 8, 2024 — sol 4357, or Martian day 4.357, of the Mars Science Laboratory mission — at 00:06:17 UTC. NASA/JPL-Caltech Earth planning date: Friday, Nov. 8, 2024
After the excitement of Wednesday’s plan, it was a relief to come in today to hear that the drive toward our exit from Gediz Vallis completed successfully and that we weren’t perched on any rocks or in any other precarious position. This made for a very smooth planning morning, which is always nice on a Friday after a long week.
But that isn’t to say that Curiosity will be taking it easy for the weekend. Smooth planning means we have lots of time to pack in as much science as we can fit. Today, this meant that the geology group (GEO) got to name eight new targets, and the environmental group (ENV) got to spend some extra time contemplating the atmosphere. Reading through the list of target names from GEO felt a bit like reading a travel guide — top rocks to visit when you’re exiting Gediz Vallis!
If you look to the front of your rover, what we refer to as the “workspace” (and which you can see part of in the image above), you’ll see an array of rocks. Take in the polygonal fractures of “Colosseum Mountain” and be amazed by the structures of “Tyndall Creek” and “Cascade Valley.” Get up close and personal with our contact science targets, “Mahogany Creek,” “Forester Pass,” and “Buttress Tree.” Our workspace has something for everyone, including the laser spectrometers in the family, who will find plenty to explore with “Filly Lake” and “Crater Mountain.” We have old favorites too, like the upper Gediz Vallis Ridge and the Texoli outcrop.
After a busy day sightseeing, why not kick back with ENV and take a deep breath? APXS and ChemCam have you covered, watching the changing atmospheric composition. Look up with Navcam and you may see clouds drifting by, or spend some time looking for dust devils in the distance. Want to check the weather before planning your road trip? Our weather station REMS works around the clock, and Mastcam and Navcam are both keeping an eye on how dusty the crater is.
All good vacations must come to an end, but know that when it’s time to drive away there will be many more thrilling sights to come!

Sols 4357–4358: Turning West
NASA’s Mars rover Curiosity acquired this image of its middle and right-rear wheels, using its Left Navigation Camera (Navcam). The difference in elevation between these two wheels at this location caused the drive planned on Monday, Nov. 4, 2024, to end early. Curiosity captured the image on Nov. 5, 2024, on sol 4355 — Martian day 4,355 of the Mars Science Laboratory mission — at 23:35:56 UTC. NASA/JPL-Caltech Earth planning date: Wednesday, Nov. 6, 2024
Sols 4357–4358: Turning West
If you’ve ever driven down a road that’s in need of repaving, you’ll know that it can be an uncomfortable experience. The same is true on Mars: even at our carefully slow driving speed, the rough, rocky terrain that we’ve found ourselves in since entering Gediz Vallis many months ago continues to present challenges for our intrepid rover.
Planning today began with the news that Curiosity only made it about halfway to its intended destination from Monday. The drive terminated early after the rover exceeded one of its “suspension limits.” This refers to our “rocker-bogie” suspension system, which allows the rover to drive over obstacles while minimizing the motion experienced by the rover body. In this case, our right middle wheel is down in a trough while the right rear wheel is perched on a rock, causing the angle of the “bogie” connecting the two wheels to exceed the maximum allowed value (Those maximums are set with a healthy amount of safety margin, so we’re not in any danger!). You can see the state of the bogie in the image above. On top of that, ending the drive early also meant that we didn’t have the images that we usually use to determine if the rover is stable enough to unstow the arm, so some creative work was necessary to determine whether or not we could. Unsurprisingly, the verdict was that we shouldn’t do so while in this awkward-looking position.
As always, the team was quick to pivot to a remote sensing plan. The focus today was on getting any last-minute remote observations of the Gediz Vallis channel. This was because we decided that, rather than continuing to drive north, we would be starting our western turn toward the exit out of Gediz Vallis.
The first sol of today’s plan contains a hefty two hours of science activities. These include LIBS observations of a bedrock target “North Dome” and a pair of ChemCam passive rasters of “Jewelry Lake” and “Merced River,” two smaller rocks near the rover, the latter of which appears to have been broken open as the rover drove over it. Mastcam will then take a documentation image of North Dome, as well as a mosaic of some more bedrock at “Earthquake Dome.” This first sol also includes a set of environmental science observations, including a lengthy 30-minute dust devil movie, just over 10 minutes of Navcam cloud movies, and some Navcam monitoring of dust and sand on the rover deck. We also sneak in a Navcam line-of-sight mosaic of the north crater rim, to measure the amount of dust in the air after our drive.
The second sol is a fairly typical post-drive sol, beginning with a standard ChemCam AEGIS activity to let the rover autonomously select a LIBS target. The rest of the science time this sol is dedicated to environmental monitoring, including a Mastcam tau observation to monitor dust, some more Navcam deck monitoring, another Navcam cloud movie, and a 360-degree Navcam dust devil survey. No arm activities means the second sol also includes a Navcam shunt prevention activity (SPENDI) to burn off some extra power while also looking for clouds and dust devils. As always, REMS, RAD, and DAN will continue their standard activities throughout this plan.
When I joined the mission back in 2020, I would occasionally look at Gediz Vallis on our HiRISE maps and imagine what the view would be like between those tall, steep channel walls. So it seems almost unbelievable that we will soon be leaving Gediz Vallis behind us as we continue our trek up Mount Sharp. It will probably still be a few more weeks before we can say that we’ve officially exited Gediz Vallis, but I don’t think anyone will be saying they were disappointed with what we accomplished during this long-anticipated phase of the mission.
Onwards and upwards!

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The NISAR mission will help researchers get a better understanding of how Earth’s surface changes over time, including in the lead-up to volcanic eruptions like the one pictured, at Mount Redoubt in southern Alaska in April 2009.R.G. McGimsey/AVO/USGS Data from NISAR will improve our understanding of such phenomena as earthquakes, volcanoes, and landslides, as well as damage to infrastructure.
We don’t always notice it, but much of Earth’s surface is in constant motion. Scientists have used satellites and ground-based instruments to track land movement associated with volcanoes, earthquakes, landslides, and other phenomena. But a new satellite from NASA and the Indian Space Research Organisation (ISRO) aims to improve what we know and, potentially, help us prepare for and recover from natural and human-caused disasters.
The NISAR (NASA-ISRO Synthetic Aperture Radar) mission will measure the motion of nearly all of the planet’s land and ice-covered surfaces twice every 12 days. The pace of NISAR’s data collection will give researchers a fuller picture of how Earth’s surface changes over time. “This kind of regular observation allows us to look at how Earth’s surface moves across nearly the entire planet,” said Cathleen Jones, NISAR applications lead at NASA’s Jet Propulsion Laboratory in Southern California.
Together with complementary measurements from other satellites and instruments, NISAR’s data will provide a more complete picture of how Earth’s surface moves horizontally and vertically. The information will be crucial to better understanding everything from the mechanics of Earth’s crust to which parts of the world are prone to earthquakes and volcanic eruptions. It could even help resolve whether sections of a levee are damaged or if a hillside is starting to move in a landslide.
The NISAR mission will measure the motion of Earth’s surface — data that can be used to monitor critical infrastructure such as airport runways, dams, and levees. NASA/JPL-Caltech What Lies Beneath
Targeting an early 2025 launch from India, the mission will be able to detect surface motions down to fractions of an inch. In addition to monitoring changes to Earth’s surface, the satellite will be able to track the motion of ice sheets, glaciers, and sea ice, and map changes to vegetation.
The source of that remarkable detail is a pair of radar instruments that operate at long wavelengths: an L-band system built by JPL and an S-band system built by ISRO. The NISAR satellite is the first to carry both. Each instrument can collect measurements day and night and see through clouds that can obstruct the view of optical instruments. The L-band instrument will also be able to penetrate dense vegetation to measure ground motion. This capability will be especially useful in areas surrounding volcanoes or faults that are obscured by vegetation.
“The NISAR satellite won’t tell us when earthquakes will happen. Instead, it will help us better understand which areas of the world are most susceptible to significant earthquakes,” said Mark Simons, the U.S. solid Earth science lead for the mission at Caltech in Pasadena, California.
Data from the satellite will give researchers insight into which parts of a fault slowly move without producing earthquakes and which sections are locked together and might suddenly slip. In relatively well-monitored areas like California, researchers can use NISAR to focus on specific regions that could produce an earthquake. But in parts of the world that aren’t as well monitored, NISAR measurements could reveal new earthquake-prone areas. And when earthquakes do occur, data from the satellite will help researchers understand what happened on the faults that ruptured.
“From the ISRO perspective, we are particularly interested in the Himalayan plate boundary,” said Sreejith K M, the ISRO solid Earth science lead for NISAR at the Space Applications Center in Ahmedabad, India. “The area has produced great magnitude earthquakes in the past, and NISAR will give us unprecedented information on the seismic hazards of the Himalaya.”
Surface motion is also important for volcano researchers, who need data collected regularly over time to detect land movements that may be precursors to an eruption. As magma shifts below Earth’s surface, the land can bulge or sink. The NISAR satellite will help provide a fuller picture for why a volcano deforms and whether that movement signals an eruption.
Finding Normal
When it comes to infrastructure such as levees, aqueducts, and dams, NISAR’s ability to provide continuous measurements over years will help to establish the usual state of the structures and surrounding land. Then, if something changes, resource managers may be able to pinpoint specific areas to examine. “Instead of going out and surveying an entire aqueduct every five years, you can target your surveys to problem areas,” said Jones.
The data could be equally valuable for showing that a dam hasn’t changed after a disaster like an earthquake. For instance, if a large earthquake struck San Francisco, liquefaction — where loosely packed or waterlogged sediment loses its stability after severe ground shaking — could pose a problem for dams and levees along the Sacramento-San Joaquin River Delta.
“There’s over a thousand miles of levees,” said Jones. “You’d need an army to go out and look at them all.” The NISAR mission would help authorities survey them from space and identify damaged areas. “Then you can save your time and only go out to inspect areas that have changed. That could save a lot of money on repairs after a disaster.”
More About NISAR
The NISAR mission is an equal collaboration between NASA and ISRO and marks the first time the two agencies have cooperated on hardware development for an Earth-observing mission. Managed for the agency by Caltech, JPL leads the U.S. component of the project and is providing the mission’s L-band SAR. NASA is also providing the radar reflector antenna, the deployable boom, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and payload data subsystem. The U R Rao Satellite Centre in Bengaluru, India, which leads the ISRO component of the mission, is providing the spacecraft bus, the launch vehicle, and associated launch services and satellite mission operations. The ISRO Space Applications Centre in Ahmedabad is providing the S-band SAR electronics.

Sols 4355-4356: Weekend Success Brings Monday Best
NASA’s Mars rover Curiosity acquired this image of the contact science target “Black Bear Lake” from about 7 centimeters away (about 3 inches), using its Mars Hand Lens Imager (MAHLI). The MAHLI, located on the turret at the end of the rover’s robotic arm, used an onboard focusing process to merge multiple images of the same target into a composite image, on Nov. 3, 2024 – sol 4353, or Martian day 4,353 of the Mars Science Laboratory Mission – at 21:36:01 UTC. NASA/JPL-Caltech/MSSS Earth planning date: Monday, Nov. 4, 2024
After a spooky week last week, it’s great to see all our weekend plans succeed as planned! We don’t take success for granted as a rover going on 13 years. With all of the science at our fingertips and all the battery power we could need, the team took right advantage of this two-sol touch-and-go Monday plan. We have a bedrock DRT target for APXS and MAHLI named “Epidote Peak” and a MAHLI-only target of a crushed rock we drove over named “Milly’s Foot Path.”
APXS data is better when it’s cold, so we’ve planned the DRT brushing and APXS to start our first sol about 11:14 local Gale time. MAHLI images are usually better in the afternoon lighting, so we’ll leave the arm unstowed and spend some remote science time beforehand, about 12:15 local time. ChemCam starts that off with a LIBS raster over a bedrock block with some interesting light and dark layering, named “Albanita Meadows” and seen here in the the upper-right-ish of this Navcam workspace frame. ChemCam will then take a long-distance RMI mosaic of a portion of the upper Gediz Vallis ridge to the north. Mastcam continues the remote science with an Albanita Meadows documentation image, a 21-frame stereo mosaic of some dark-toned upturned blocks about 5 meters away (about 16 feet), a four-frame stereo mosaic of some polygonal fracture patterns about 20 meters away (about 66 feet), and a mega 44-frame stereo mosaic of Wilkerson butte, upper Gediz Vallis ridge, “Fascination Turret,” and “Pinnacle Ridge” in the distance. That’s a total of 138 Mastcam images! With remote sensing complete, the RSM will stow itself about 14:00 local time to make time for MAHLI imaging.
Between about 14:15 and 14:30 local time, MAHLI will take approximately 64 images of Epidote Peak and Milly’s Foot Path. Most of the images are being acquired in full shadow, so there is uniform lighting and saturation in the images. We’ll stow the arm at about 14:50 and begin our drive! This time we have an approximately 34-meter drive to the northwest (about 112 feet), bringing us almost all the way to the next dark-toned band in the sulfate unit. But no matter what happens with the drive, we’ll still do some remote science on the second sol including a Mastcam tau observation, a ChemCam LIBS in-the-blind (a.k.a AEGIS: Autonomous Exploration for Gathering Increased Science), and some Navcam movies of the sky and terrain.
