NASA's Curiosity Mars Rover

Drive details

Map (50 meter scale bar)

Looks like a good drive. I'll post the drive details and additional images once they come down from the rover :)

This panorama is assembled from 31 overlapping post-drive R-NavCam images. Looks to me that the rover is closing in on the last sections of the box-work terrain where it made some interesting discoveries. Once it completes its activities at this area, it will begin its journey further south and higher up the slopes of Mt Sharp in Gale crater. Image Credits: NASA/JPL-Caltech

MAHLI uses an onboard process to merge multiple images of the same target, making a composite that brings as many features as possible into focus. Curiosity performed the merge on March 5, 2026 — Sol 4827, or Martian day 4,827 of the Mars Science Laboratory Mission — at 19:56:40 UTC. NASA/JPL-Caltech/MSSS

Curiosity is in the last stage of its exploration of the spiderweb-like boxwork unit. This stage consists of exploring the eastern and southern borders of this terrain. There were two multi-sol plans assembled this week. The previous plan put Curiosity at a site on the eastern extent of the boxwork unit with bedrock that allowed for brushing and in-place measurements with APXS and MAHLI of the bedrock target “Infiernillo.” The ChemCam also took a LIBS chemical measurement of this target as well as a nodular-rich piece of bedrock assigned the name “Humahuaca.” MAHLI was tasked to image a pitted vertical rock face which was dubbed “Timboy Chaco” (part of which is shown in the MAHLI color image accompanying this report). Mastcam color mosaics and ChemCam Remote Micro-Imager (RMI) mosaics were also collected to characterize nearby terrain including a butte to the south and the geologic contact between the boxwork terrain and the adjacent layered, light-toned unit.

A midweek drive put the rover even closer to the eastern edge of the boxwork unit and set it up for two or more drives to the southern edge of the boxwork. The workspace present for Friday planning included bedrock exposures and a dark-toned float rock. The float rock was large enough for in-situ observation by APXS, and it was also targeted for up-close imaging by MAHLI and a measurement by ChemCam to observe its reflectance properties. Some other dark float rocks observed by Curiosity in the past year have been hypothesized as being stony meteorites (chondrites). Measuring the chemistry and reflectance of this dark rock, named “Thola,” will allow the team to determine if it is native to Mars or a meteorite from beyond. The Friday plan also included ChemCam remote chemistry measurements of the smooth bedrock target “Valle Fertil” and a nodular bedrock target “Norte Grande.” The plan also included Mastcam mosaics of light-toned bedrock across the eastern contact of the boxwork unit to assess sedimentary structures and determine stratigraphic relationships, observations of smaller troughs in the regolith, and other mosaics of nearby ridges as well as a two-frame mosaic of the dark float rock Thola and another dark-toned pebble.

The plan concludes with a drive toward the southern border of the boxwork unit. Given that this southern contact is approximately 100 meters (about 109 yards) away, it will likely require two drives.

APXS is a spectrometer that measures the abundance of chemical elements in rocks and soils, is about the size of a cupcake, and is located on the turret at the end of Curiosity's robotic arm.

This week we had three planning sessions, exploring the eastern side of the boxwork unit. As a Rover Planner on Monday, I worked on the arm and drive activities, while on Friday I served as the Engineering Uplink Lead (planning all of our engineering activities like heating and managing our onboard data). We had two small drives this week to put different targets into our workspace for each plan. The months-long careful and systematic investigation of the boxwork unit will hopefully provide the science team insights on what was going on in this area of Mars that resulted in this interesting and unique terrain. As we wrap it up, we are already thinking ahead to our future investigations of the sulfate unit, where we will be heading after finishing here and continuing our climb up Mount Sharp.

With three plans and short drives, we were able to do a total of 19 Mastcam stereo mosaics, getting a full 360-degree panorama as well as additional documentation of the nearby ridges/hollows and the nearby sulfate unit. Some of the rocks in the hollows show a return of the polygonal structures that we saw in abundance prior to entering the boxwork unit, but have only seen sparsely in other hollows. As we are entering deeper into the warmer months, the start of dust-storm season, we have also been doing a lot of atmospheric measurements. We did multiple observations of the crater rim (to watch it fading into the haze), Mastcam solar Tau measurements (looking at the Sun to measure dust in the atmosphere), dust-devil movies, and other sky observations.

We investigated a total of four targets with MAHLI and APXS, two of which we were able to brush. The accompanying image shows the APXS down on one of the targets near the contact. Most of the targets were not very complicated for the Rover Planners because the rocks have been mostly smooth and flat. But our Wednesday target, “Los Monos,” was slightly under the front of the rover, and we had to do some additional intermediate arm motions to reach underneath safely. We won’t actually know if today’s targets are on the other side of the contact (in the sulfate unit) or not until we can study the data.

Planning the short drives has been interesting, as with most of the boxwork unit drives, because we must navigate around the sand and steeper slopes in hopes of minimizing slip. In this weekend’s plan our drive will head south towards the southern end of the boxwork unit, where the terrain smooths out a bit and driving should be easier.

NASA’s Mars rover Curiosity acquired this Navcam image looking out towards the northern rim of Gale Crater. Compared to just a few months ago, the view is much hazier, reflecting the higher amount of atmospheric dust that is typical of this time of year.

This has been a pretty routine week for Curiosity. As was mentioned last week, we're now in the final phase of the boxwork exploration campaign. We're currently making our way toward the eastern contact of the boxwork formation with the surrounding geology, which we plan to drive along before turning our attention to the southern contact. That will likely be our last opportunity to directly interrogate the boxwork area before we continue our adventure up the slopes of Mount Sharp.

Along the way, we've been performing our usual investigations of the geology that we encounter at our parking locations. As always, this includes contact science on bedrock targets close to the rover, ChemCam LIBS observations of targets slightly further afield, and a number of ChemCam RMI and Mastcam mosaics. These mosaics include observations deeper into the “Tapiche” hollow where we're parked and the “Los Flamencos” ridge to its south, which we plan on investigating closer in the coming week.

Mars continues to move deeper into its dusty season, so the environmental science group filled this week's plan with a typical assortment of atmospheric monitoring activities to track dust devils and the amount of dust in the atmosphere, as well as several Navcam cloud movies. So far this dusty season the atmosphere over Gale Crater appears to be behaving much like it does most years, with no signs of imminent dust storms. It's now been almost eight years (four Mars years) since the last time that a global dust storm swept across the planet, so we're keeping a close eye on the possibility of another one occurring this year.

NASA’s Curiosity Mars rover used LED lights on the end of its robotic arm to create this rare nighttime view of the Red Planet’s surface on December 6, 2025, the 4,740th Martian day, or sol, of the rover’s mission.

The LED lights are part of the Mars Hand Lens Imager, or MAHLI, a camera on the end of Curiosity’s robotic arm. The image was captured by the Mast Camera, or MastCam, on the rover’s mast, or “head.” On occasion, scientists have used MAHLI’s LED lights to illuminate areas deep in shadow during the day, such as the insides of drill holes and the inlet tubes leading to instruments in the rover’s belly. Much earlier in the mission, the Curiosity team used these LEDs at night to look for layering or other features in drill hole walls that would help them understand a rock’s composition. Since the mission changed its drilling method, the drill holes have come out too rough and dusty to see any such details.

After drilling a rock target nicknamed “Nevado Sajama” on November 13, 2025 (Sol 4,718), the team noticed the drill hole walls were smooth enough to try looking for layers and decided to try illuminating the drill hole at night. This drill hole was made during Curiosity’s exploration of a region full of geologic formations called boxwork, which crisscross the surface for miles and look like giant spiderwebs when viewed from space.

Mars is currently on the other side of the sun and communications with the rovers and orbiters are not possible for a couple more weeks.

So I'm taking this opportunity to share a few of my favourite images acquired during the mission.

This rather scenic path to the 5 kilometer high Martian mountain called Aeolis Mons (aka Mt Sharp) passes the Murray Buttes that are seen here on the right side of this cropped mosaic using just 8 overlapping mast camera images that I assembled using MS ICE.

While at this location the rover drilled into the mudstone bedrock on the surface of the Murray formation and obtained a sample of powdered rock for analysis from a target called 'Marimba'. The raw images were acquired on mission Sol 1419 (August 03, 2016). Just 2 sols before Curiosity Rover celebrated its 4th anniversary on the planet Mars, landing on August 05, 2012 (PDT) I have stretched the colours and contrast to highlight the terrain on the Buttes and the flanks of the mountain.

Wheel Condition Check

Curiosity Rover used its Hand Lens Imager (MAHLI) around 4 pm (local time) during mission Sol 1355, May 29, 2016 to acquire a set of images of its wheels. These were periodic checks to allow the rover's engineers to assess the accumulated wear and tear to its 6 aluminum wheels.

The MAHLI camera is located on the end of the rover's 2-meter long robotic arm. Images of the wheels are acquired by extending the arm away from the rover and then lowering it close to the ground.

I have corrected the rotation of the image and enhanced the colours a little.

For scale the rovers wheel diameter is 50 centimeters or about 20 inches, width is 40 centimeters, or 16 inches The distant base of the Gale crater rim mountains, seen at the top of this image were ~30 kilometers (~19 miles) from the rover's location in May 2016.

Curiosity Mars rover used its black-and-white navigation cameras to capture panoramas at two times of day on Nov. 18, 2025, spanning periods that occurred on both the 4,722nd and 4,723rd Martian days, or sols, of the mission. The panoramas were captured at 4:15 p.m. on Sol 4,722 and 8:20 a.m. on Sol 4,723 (both at local Mars time), then merged together. Color was later added for an artistic interpretation of the scene with blue representing the morning panorama and yellow representing the afternoon one.

The resulting “postcard” is similar to ones the rover took in June 2023 and November 2021. Adding color to these kinds of merged images helps different details stand out in the landscape.

The scene captured in this postcard shows Curiosity at the top of a ridge referred to as a boxwork formation. These formations crisscross a region in the lower foothills of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain which Curiosity has been climbing since 2014.

Curiosity used the drill on the end of its robotic arm to collect a rock sample from the top of this ridge at a spot nicknamed “Nevado Sajama.” This view looks north across the boxwork formations and downslope of Mount Sharp toward the floor of Gale Crater, a vast impact crater the mountain is located within. The crater’s rim can be seen far in the distant horizon, approximately 25 miles (40 kilometers) away. Wheel tracks are visible in the hollow behind Curiosity, where a sample was also drilled at a spot nicknamed “Valle de la Luna.”

The boxwork formations are believed to have been created billions of years ago when water on ancient Mars dripped through rock cracks, carrying minerals with them. The minerals hardened after the water dried up; eons later, wind sandblasted the softer rock around these hardened minerals, exposing the ridges Curiosity is exploring today. These ridges may reveal more about the planet’s watery past.
