Curiosity Blog, Sols 4602-4603: On Top of the Ridge
NASA’s Mars rover Curiosity acquired this image looking along the ridge it is exploring during its planned activities for July 16, 2025. Curiosity acquired this image using its Left Navigation Camera on July 15 — Sol 4600, or Martian day 4,600 of the Mars Science Laboratory mission — at 17:12:14 UTC. NASA/JPL-Caltech Written by Alex Innanen, Atmospheric Scientist at York University
Earth planning date: Wednesday, July 16, 2025
As we hoped, we successfully climbed the 11-meter ramp (about 36 feet) and have arrived at the top of the ridge and the start of the main boxwork region. This means we’re moving into the next phase of the boxwork campaign, which is all about assessing these features and how we can navigate our way through them, and learning everything we can about their composition.
In support of that, we’re taking a good look around at the boxwork ridges with both ChemCam and Mastcam. Both instruments are taking mosaics of the more distant ridges to get a broader view of their features. A bit closer in, Mastcam has three more mosaics: two looking at different views of “El Corral” and “Chapare,” both of which we saw in Monday’s plan, and “Meson,” which is the ridge we’ll be heading for in today’s 15-meter drive (about 49 feet).
It’s not all looking ahead, though. The workspace in front of us has a lot to offer as well. Mastcam will be turning its sights to some nearby linear features. Our workspace is also full of nodular bedrock, which is getting lots of up-close attention. ChemCam will be turning its LIBS laser on a target called “Altamora,” and MAHLI and APXS will be examining another target called “Nocarane.”
With all the geological excitement, we can still manage to squeeze in some time to keep an eye on the environment. Though we don’t always mention them, REMS, RAD, and DAN are always there working steadily away to build up our understanding of Mars’ environment. We’ll also round out the plan with a suprahorizon cloud movie and a 360-degree dust-devil survey.

Hubble Digs Up Galactic Time Capsule
This NASA/ESA Hubble Space Telescope image features the globular cluster NGC 1786. ESA/Hubble & NASA, M. Monelli; Acknowledgment: M. H. Özsaraç This NASA/ESA Hubble Space Telescope image features the field of stars that is NGC 1786. This globular cluster is located in the Large Magellanic Cloud (LMC), a small satellite galaxy of the Milky Way Galaxy that is approximately 160,000 light-years away from Earth. NGC 1786 itself is in the constellation Dorado. It was discovered in the year 1835 by Sir John Herschel.
The data for this image comes from an observing program that compares old globular clusters in nearby dwarf galaxies — the LMC, the Small Magellanic Cloud, and the Fornax dwarf spheroidal galaxy — to globular clusters in the Milky Way galaxy. Our galaxy contains over 150 of these old, spherical collections of tightly-bound stars, which astronomers have studied in depth — especially with Hubble images like this one, which show them in previously unattainable detail. Being very stable and long-lived, globular clusters act as galactic time capsules, preserving stars from the earliest stages of a galaxy’s formation.
Astronomers once thought that stars in a globular cluster all formed together at about the same time, but the study of old globular clusters in our galaxy uncovered multiple populations of stars with different ages. To use globular clusters as historical markers, we must understand how they form and where these stars of varying ages come from. This observing program examined old globular clusters like NGC 1786 in these external galaxies to see if they, too, contain multiple populations of stars. This research can tell us more about how the LMC originally formed, but also the Milky Way Galaxy, too.

NASA Citizen Science and Your Career: Stories of Exoplanet Watch Volunteers
Doing NASA Science brings many rewards. But can taking part in NASA citizen science help your career? To find out, we asked participants in NASA’s Exoplanet Watch project about their experiences. In this project, amateur astronomers work together with professionals to track planets around other stars.
First, we heard from professional software programmers. Right away, one of them told us about getting a new job through connections made in the project.
“I decided to create the exoplanet plugin, [for citizen science] since it was quite a lot of manual work to check which transits were available for your location. The exoplanet plugin and its users got me in contact with the Stellar group… Through this group, I got into contact with a company called OurSky and started working for them… the point is, I created a couple of plugins for free and eventually got a job at an awesome company.”
Another participant talked about honing their skills and growing their confidence through Exoplanet Watch.
“There were a few years when I wasn’t actively coding. However, Exoplanet Watch rekindled that spark…. Participating in Exoplanet Watch even gave me the confidence to prepare again for a technical interview at Meta—despite having been thoroughly defeated the first time I tried.”
Teachers and teaching faculty told us how Exoplanet Watch gives them the ability to better convey what scientific research is all about – and how the project motivates students!
“Exoplanet Watch makes it easy for undergraduate students to gain experience in data science and Python, which are absolutely necessary for graduate school and many industry jobs.”
“Experience with this collaborative work is a vital piece of the workforce development of our students who are seeking advanced STEM-related careers or ongoing education in STEM (Science, Technology, Engineering, & Mathematics) fields after graduation… Exoplanet Watch, in this way, is directly training NASA’s STEM workforce of tomorrow by allowing CUNY (The City University of New York) students to achieve the science goals that would otherwise be much more difficult without its resources.”
One aspiring academic shared how her participation on the science team side of the project has given her research and mentorship experience that strengthens her resume.
“I ended up joining the EpW team to contribute my expertise in stellar variability… My involvement with Exoplanet Watch has provided me with invaluable experience in mentoring a broad range of astronomy enthusiasts and working in a collaborative environment with people from around the world. … Being able to train others, interact in a team environment, and work independently are all critical skills in any work environment, but these specific experiences have also been incredibly valuable towards building my portfolio as I search for faculty positions around the USA.”
There are no guarantees, of course. What you get out of NASA citizen science depends on what you put in. But there is certainly magic to be found in the Exoplanet Watch project. As one student said:
“Help will always be found at Hogwarts, to those who need it.” Exoplanet Watch was definitely Hogwarts for me in my career as an astronomer!”
For more information about NASA and your career, check out NASA’s Surprisingly STEM series highlighting exciting and unexpected jobs at NASA, or come to NASA Career Day, a virtual event for students and educators. Participants must register by September 4, 2025. The interactive platform will be open from September 15-19, with live panels and events taking place on September 18.

Curiosity Blog, Sols 4600-4601: Up and Over the Sand Covered Ramp
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on July 13, 2025 — Sol 4598, or Martian day 4,598 of the Mars Science Laboratory mission — at 15:24:10 UTC. NASA/JPL-Caltech Written by Sharon Wilson Purdy, Planetary Geologist at the Smithsonian National Air and Space Museum
Earth planning date: Monday, July 14, 2025
The Curiosity rover continues to navigate through the region of Mount Sharp characterized by the boxwork terrain. After successfully completing a drive of about 34 meters over the weekend (about 112 feet), the rover parked near the edge of a smooth, sandy stretch at the base of a ridge that leads to the most prominent and complex network of boxwork structures seen so far.
Due to the lack of exposed bedrock in the immediate workspace, the science team opted to give some of the rover’s contact science instruments a break. With the dust removal tool (DRT) and APXS instruments stowed, the extra energy allowed the Mars Hand Lens Imager (MAHLI) to take high resolution images of “Playa de la Gallina” to survey the uniform, smooth surface consisting of sand and pebble-sized material.
The ChemCam and Mastcam teams scheduled several observations in this two-sol plan that further investigated the rocks and structures in our immediate vicinity and surroundings. ChemCam LIBS was used to target “El Olivo” to determine the chemistry of the bumpy textured bedrock near the rover, which was also imaged by a Mastcam stereo mosaic. Additional Mastcam stereo mosaics include fractures at “El Corral” and linear troughs at “Chapare.” Further away, ChemCam’s Remote Micro Imager (RMI) will provide insight into an intriguing section of scoured features within the Mishe Mokwa butte.
The environmental working group continues to keep an eye in the sky and planned a supra-horizon movie and a dust-devil survey as part of their ongoing monitoring campaign of the atmospheric conditions in Gale Crater.
The 21-meter-long drive (about 69 feet) at the end of this plan will maneuver the rover past the sandy ramp to the top of the main boxwork region. From here, the science team will be able to explore this fascinating area of particularly large boxwork structures. Stay tuned as Curiosity continues to climb higher and delve deeper into the geologic history of Mars!
