Curiosity Blog, Sols 4584 – 4585: Just a Small Bump
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on June 27, 2025 — Sol 4582, or Martian day 4,582 of the Mars Science Laboratory mission — at 05:28:57 UTC. NASA/JPL-Caltech Written by Abigail Fraeman, Deputy Project Scientist at NASA’s Jet Propulsion Laboratory
Earth planning date: Friday, June 27, 2025
We weren’t able to unstow Curiosity’s robotic arm on Wednesday because of some potentially unstable rocks under Curiosity’s wheels, but we liked the rocks at Wednesday’s location enough that we decided to spend a sol repositioning the rover so that we’d have another chance today to analyze them. The small adjustment of the rover’s position, or “bump,” as we like to call it during tactical planning, was successful, and we found ourselves in a nice stable pose this morning which allowed us to use our highly capable robotic arm to observe the rocks in front of us.
We will be collecting APXS and MAHLI observations of two targets today. The first, “Santa Elena,” is the bumpy rock that caught our eye on Wednesday. The second, informally named “Estancia Allkamari,” is a patch of nearby sand. We’ll analyze this target to understand if and how the sand composition has changed as we’ve driven across Mount Sharp, and to better help us understand how sand may be contributing to future compositional measurements that cover mixtures of sand and rock. MAHLI and ChemCam will team up to observe a third target named “Ticatica,” which is another bumpy rock nearby that looks like it might have a dark patch on its side.
This is the final weekend of this Martian year when temperature and relative humidity in Gale crater hit the sweet spot where conditions are right for frost to form in the pre-dawn hours. We’re taking this last opportunity to see if we can catch any evidence of frost with the ChemCam laser, shooting a sandy (and hopefully cold) portion of the ground in the pre-dawn hours on a target named “Rio Huasco.” Other activities in the plan include atmospheric monitoring, Mastcam mosaics, including a 20 x 3 mosaic of the large boxwork structures in the distance, and a short drive to the southwest to check out a rocky raised ridge.

Hubble Studies Small but Mighty Galaxy
This NASA/ESA Hubble Space Telescope features the nearby galaxy NGC 4449. ESA/Hubble & NASA, E. Sabbi, D. Calzetti, A. Aloisi This portrait from the NASA/ESA Hubble Space Telescope puts the nearby galaxy NGC 4449 in the spotlight. The galaxy is situated just 12.5 million light-years away in the constellation Canes Venatici (the Hunting Dogs). It is a member of the M94 galaxy group, which is near the Local Group of galaxies that the Milky Way is part of.
NGC 4449 is a dwarf galaxy, which means that it is far smaller and contains fewer stars than the Milky Way. But don’t let its small size fool you — NGC 4449 packs a punch when it comes to making stars! This galaxy is currently forming new stars at a much faster rate than expected for its size, which makes it a starburst galaxy. Most starburst galaxies churn out stars mainly in their centers, but NGC 4449 is alight with brilliant young stars throughout. Researchers believe that this global burst of star formation came about because of NGC 4449’s interactions with its galactic neighbors. Because NGC 4449 is so close, it provides an excellent opportunity for Hubble to study how interactions between galaxies can influence the formation of new stars.
Hubble released an image of NGC 4449 in 2007. This new version incorporates several additional wavelengths of light that Hubble collected for multiple observing programs. These programs encompass an incredible range of science, from a deep dive into NGC 4449’s star-formation history to the mapping of the brightest, hottest, and most massive stars in more than two dozen nearby galaxies.
The NASA/ESA/CSA James Webb Space Telescope has also observed NGC 4449, revealing in intricate detail the galaxy’s tendrils of dusty gas, glowing from the intense starlight radiated by the flourishing young stars.

NASA’s RASSOR (Regolith Advanced Surface Systems Operations Robot) undergoes testing to extract simulated regolith, or the loose, fragmental material on the Moon’s surface, inside of the Granular Mechanics and Regolith Operations Lab at the agency’s Kennedy Space Center in Florida on May 27. Ben Burdess, mechanical engineer at NASA Kennedy, observes RASSOR’s counterrotating drums digging up the lunar dust and creating a three-foot berm.
The opposing motion of the drums helps RASSOR grip the surface in low-gravity environments like the Moon or Mars. With this unique capability, RASSOR can traverse the rough surface to dig, load, haul, and dump regolith that could later be broken down into hydrogen, oxygen, or water, resources critical for sustaining human presence.
The primary objective was testing the bucket drums that will be used on NASA’s IPEx (In-Situ Resource Utilization Pilot Excavator). The RASSOR robot represents an earlier generation technology that informed the development of IPEx, serving as a precursor and foundational platform for the advanced excavation systems and autonomous capabilities now being demonstrated by this Moon-mining robot.

Sols 4554–4555: Let’s Try That One Again…

Earth planning date: Wednesday, May 28, 2025
We came in early this morning and learned that part of Tuesday’s plan didn’t execute on Mars due to a temporary issue with the arm. We collected APXS data on the target “Palo Verde Mountains,” but were not able to take the corresponding MAHLI images or drive away. So it was a straightforward decision for the planning team today to pick up where we left off yesterday, giving ourselves a second chance to collect the MAHLI observation and then complete the same 29.5-meter drive to the west (about 97 feet) that we had planned on Tuesday.
We love making lemonade from lemons when things don’t go exactly as expected in rover tactical planning, and today was no exception. Since we’re sticking around for a little bit longer, the science team decided to collect additional mosaics of impressive nearby features, including a 15×2 Mastcam mosaic of the “Mishe Mokwa” hill and an 11×2 Mastcam mosaic of fractures near “Lake Cachuma.” We’re also having another go at taking the epically long, long-distance RMI mosaic of a crater 91 kilometers away from Curiosity (almost 57 miles) that we planned yesterday, and we’re playing around with the focus settings to see if we can get a sharper image.
The team also had time for a second RMI mosaic of our very well-imaged “Texoli” butte, and a ChemCam LIBS observation on a target named “Santa Monica Bay,” which is just above the “Sisquoc River” target we observed yesterday on the bumpy rock in our workspace. As usual, we will also continue to monitor the environment around us with REMS, RAD, Navcam, and Mastcam observations.
