Earth planning date: Monday, July 28, 2025
Today was a pretty straightforward day of planning. Our drive over the weekend completed successfully, and we quickly confirmed that we are parked in a stable position. Thus, we were able to unstow the rover’s arm to poke around in our new workspace, which features a large sand-filled fracture. Aside from all of the good geology work to be done, the view from our current location is quite spectacular.
We’re still in the time of year where the atmosphere at Gale is reasonably dust-free (at least, compared to later in the year), allowing us to look all the way out to and beyond the Gale crater rim. The upper slopes of Mount Sharp have also re-emerged to our east after spending months hidden behind the walls of Gediz Vallis. There’s a bit more sand and dust in this location than we’ve seen recently, so we can also see the trail left behind by the rover’s wheels as we drove to this location (see the image above).
We’re still deep in our examination of the boxwork structures that we’re now driving through, so most of Curiosity’s attention in this plan is focused much closer to the rover than any of the scenic vista surrounding us. APXS, DRT, and MAHLI will all take a look at “Cañón de Palca,” some bedrock close to the large fracture in this workspace. Mastcam and ChemCam RMI will image some boxwork ridges at “Caine,” and will also collaborate on imaging of the weekend’s post-drive AEGIS target and a LIBS bedrock target “Doña Ines.” Mastcam’s solo activities include taking a look at some layering at “Paniri butte” and at MAHLI to examine a speck of dust that may have fallen on the lens.
We’ll be driving away from this location along one of the boxwork ridges, which, at about 5 meters (about 16 feet) wide, is more than large enough to fit our car-sized rover. Post-drive activities are largely focused on environmental monitoring, including Navcam line-of-sight and dust-devil surveys to look at dust, and several Navcam cloud movies. As usual, ChemCam will also join the post-drive fun with an AEGIS observation. More environmental monitoring by REMS, RAD, and DAN fill out the remainder of this plan.

Spheres in the Sand NASA’s Perseverance rover captured this image of spherule-bearing regolith at Rowsell Hill using its arm-mounted WATSON camera on July 5, 2025 — Sol 1555, or Martian day 1,555 of the Mars 2020 mission — at the local mean solar time of 12:46:29. WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) is a close-range color camera that works with the rover’s SHERLOC instrument (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals); both are located on the turret at the end of the rover’s robotic arm. NASA/JPL-Caltech
Written by Andrew Shumway, Postdoctoral Researcher at the University of Washington
It is not common for a rover to spot nearly perfect spheres in the soil beneath its wheels. Over two decades ago, the Opportunity rover famously discovered spherules made of hematite (nicknamed “blueberries”) near its landing site in Meridiani Planum. More recently, the Perseverance rover has similarly encountered spherules embedded in bedrock and loosely scattered throughout the region informally called “Witch Hazel Hill.” In a previous blog post, we described Perseverance’s investigations of a spherule-bearing outcrop at the “Hare Bay” abrasion patch, where the team later collected a core. With the “Bell Island” sample added to the rover’s collection, the science team next decided to take a closer look at loose spherules in the area, which appear to have eroded out of the nearby bedrock.
On Sol 1555, while the United States was celebrating the Fourth of July with hotdogs and fireworks, Perseverance was hard at work studying spherule-rich regolith at the target “Rowsell Hill” using the proximity instruments on its robotic arm. SHERLOC’s Autofocus and Context Imager and WATSON camera both captured high resolution pictures of the target (shown above), while PIXL measured the elemental makeup of the spherules and surrounding grains.
Despite their superficial similarity to Opportunity’s “blueberries”, the spherules at “Rowsell Hill” have a very different composition and likely origin. In Meridiani Planum, the spherules were composed of the mineral hematite and were interpreted to have formed in groundwater-saturated sediments in Mars’ distant past. By comparison, the spherules in “Rowsell Hill” have a basaltic composition and likely formed during a meteoroid impact or volcanic eruption. When a meteoroid crashes into the surface of Mars, it can melt rock and send molten droplets spraying into the air. Those droplets can then rapidly cool, solidifying into spherules that rain down on the surrounding area. Alternatively, the spherules may have formed from molten lava during a volcanic eruption.
With these new data in hand, the Perseverance science team continues to search for answers about where these spherules came from. If they formed during an ancient impact, they may be able to tell us about the composition of the meteoroid and the importance of impact cratering in early Mars’s history. If they instead formed during a volcanic eruption, they could preserve clues about past volcanism in the region around Jezero crater. Either way, these spherules are a remnant of an energetic and dynamic period in Mars’ history!

NASA Selects Firefly for New Artemis Science, Tech Delivery to Moon
NASA has awarded Firefly Aerospace of Cedar Park, Texas, $176.7 million to deliver two rovers and three scientific instruments to the lunar surface as part of the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign to explore more of the Moon than ever before.
This delivery is the first time NASA will use multiple rovers and a variety of stationary instruments, in a collaborative effort with the CSA (Canadian Space Agency) and the University of Bern, to help us understand the chemical composition of the lunar South Pole region and discover the potential for using resources available in permanently shadowed regions of the Moon.
“Through CLPS, NASA is embracing a new era of lunar exploration, with commercial companies leading the way,” said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. “These investigations will produce critical knowledge required for long-term sustainability and contribute to a deeper understanding of the lunar surface, allowing us to meet our scientific and exploration goals for the South Pole region of the Moon for the benefit of all.”
Under the new CLPS task order, Firefly is tasked with delivering end-to-end payload services to the lunar surface, with a period of performance from Tuesday to March 29, 2030. The company’s lunar lander is targeted to land at the Moon’s South Pole region in 2029.
This is Firefly’s fifth task order award and fourth lunar mission through CLPS. Firefly’s first delivery successfully landed on the Moon’s near side in March 2025 with 10 NASA payloads. The company’s second mission, targeting a launch in 2026, includes a lunar orbit drop-off of a satellite combined with a delivery to the lunar surface on the far side. Firefly’s third lunar mission will target landing in the Gruithuisen Domes on the near side of the Moon in 2028, delivering six experiments to study that enigmatic lunar volcanic terrain.
“As NASA sends both humans and robots to further explore the Moon, CLPS deliveries to the lunar South Pole region will provide a better understanding of the exploration environment, accelerating progress toward establishing a long-term human presence on the Moon, as well as eventual human missions to Mars,” said Adam Schlesinger, manager of the CLPS initiative at NASA’s Johnson Space Center in Houston.
The rovers and instruments that are part of this newly awarded flight include:
- MoonRanger is an autonomous microrover that will explore the lunar surface. MoonRanger will collect images and telemetry data while demonstrating autonomous capabilities for lunar polar exploration. Its onboard Neutron Spectrometer System instrument will study hydrogen-bearing volatiles and the composition of lunar regolith, or soil.
Lead development organizations: NASA’s Ames Research Center in California’s Silicon Valley, and Carnegie Mellon University and Astrobotic, both in Pittsburgh. - Stereo Cameras for Lunar Plume Surface Studies will use enhanced stereo imaging photogrammetry, active illumination, and ejecta impact detection sensors to capture the impact of the rocket exhaust plume on lunar regolith as the lander descends on the Moon’s surface. The high-resolution stereo images will help predict lunar regolith erosion and ejecta characteristics, as bigger, heavier spacecraft and hardware are delivered to the Moon near each other in the future.
Lead development organization: NASA’s Langley Research Center in Hampton, Virginia. - Laser Retroreflector Array is an array of eight retroreflectors on an aluminum support structure that enables precision laser ranging, a measurement of the distance between the orbiting or landing spacecraft to the reflector on the lander. The array is a passive optical instrument, which functions without power, and will serve as a permanent location marker on the Moon for decades to come.
Lead development organization: NASA’s Goddard Space Flight Center in Greenbelt, Maryland. - A CSA Rover is designed to access and explore remote South Pole areas of interest, including permanently shadowed regions, and to survive at least one lunar night. The CSA rover has stereo cameras, a neutron spectrometer, two imagers (visible to near-infrared), a radiation micro-dosimeter, and a NASA-contributed thermal imaging radiometer developed by the Applied Physics Laboratory. These instruments will advance our understanding of the physical and chemical properties of the lunar surface, the geological history of the Moon, and potential resources such as water ice. It will also improve our understanding of the environmental challenges that await future astronauts and their life support systems.
Lead development organization: CSA. - Laser Ionization Mass Spectrometer is a mass spectrometer that will analyze the element and isotope composition of lunar regolith. The instrument will utilize a Firefly-built robotic arm and Titanium shovel that will deploy to the lunar surface and support regolith excavation. The system will then funnel the sample into its collection unit and use a pulsed laser beam to identify differences in chemistry compared to samples studied in the past, like those collected during the Apollo program. Grain-by-grain analyses will provide a better understanding of the chemical complexity of the landing site and the surrounding area, offering insights into the evolution of the Moon.
Lead development organization: University of Bern in Switzerland.
Through the CLPS initiative, NASA purchases lunar landing and surface operations services from American companies. The agency uses CLPS to send scientific instruments and technology demonstrations to advance capabilities for science, exploration, or commercial development of the Moon, and to support human exploration beyond to Mars. By supporting a robust cadence of lunar deliveries, NASA will continue to enable a growing lunar economy while leveraging the entrepreneurial innovation of the commercial space industry.
