Curiosity Blog, Sols 4641-4648: Thinking Outside and Inside the ‘Boxwork’
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on Aug. 28, 2025 — Sol 4643, or Martian day 4,643 of the Mars Science Laboratory mission — at 20:45:52 UTC. NASA/JPL-Caltech Written by Ashley Stroupe, Mission Operations Engineer and Rover Planner at NASA’s Jet Propulsion Laboratory
Earth planning week: Aug. 25, 2025.
This week Curiosity has been exploring the boxwork unit, investigating both the ridges and the hollows to better characterize them and understand how they may have formed. We’ve been doing lots of remote science, contact science, and driving in each plan. In addition, we have our standard daily environmental observations to look at dust in the atmosphere. We can still see distant targets like the crater rim, but temperatures will soon begin to warm up as we start moving into a dustier part of the year. And after each drive, we also use AEGIS to do some autonomous target selection for ChemCam observations. I was the arm rover planner for the 4645-4648 plan on Friday.
For Monday’s plan (sols 4641-4642), after a successful weekend drive Curiosity began on the edge of a boxwork ridge. We did a lot of imaging, including Mastcam mosaics of “El Alto,” an upturned rock near a wheel, the ridge forming the south side of the Mojo hollow, “Sauces,” our contact science target, and “Navidad,” an extension of our current workspace. We also took ChemCam LIBS of Sauces and an RMI mosaic. The rover planners did not find any bedrock large enough to brush, but did MAHLI and APXS on Sauces. Ready to drive, Curiosity drove about 15 meters (about 49 feet) around the ridge to the south and into the next hollow, named “Mojo.”
In Wednesday’s plan (sols 4643-4644), Curiosity was successfully parked in the Mojo hollow. We started with a lot of imaging, including Mastcam mosaics of the ridges around the Mojo hollow, a nearby trough and the hollow floor to look for regolith movement. We also imaged a fractured float rock named “La Laguna Verde.” ChemCam planned a LIBS target on “Corani,” a thin resistant clast sticking out of the regolith, a RMI mosaic of a target on the north ridge named “Cocotoni,” and a long-distance RMI mosaic of “Babati Mons,” a mound about 100 kilometers (about 62 miles) away that we can see peeking over the rim of Gale crater! With no bedrock in the workspace, the rover planners did MAHLI and APXS observations on a regolith target named “Tarapacá.” The 12-meter drive in this plan (about 39 feet) was challenging; driving out of the hollow and up onto the ridge required the rover to overcome tilts above 20 degrees, where the rover can experience a lot of slip. Also, with the drive late in the day, it was challenging to determine where Curiosity should be looking to track her slip using Visual Odometry without getting blinded by the sun or losing features in shadows. Making sure VO works well is particularly important on drives like this when we expect a lot of slip.
Friday’s plan, like most weekend plans, was more complex — particularly because this four-sol plan also covers the Labor Day holiday on Monday. Fortunately, the Wednesday drive was successful, and we reached the desired parking location on the ridge south of Mojo for imaging and contact science. The included image looks back over the rover’s shoulder, where we can see the ridge and hollow. We took a lot of imaging looking at hollows and the associated ridges. We are taking a Mastcam mosaic of “Jorginho Cove,” a target covering the ridge we are parked on and the next hollow to the south, “Pica,” a float rock that is grayish in color, and a ridge/hollow pair named “Laguna Colorada.” We also take ChemCam LIBS observations of Pica and two light-toned pieces of bedrock named “Tin Tin” and ”Olca.” ChemCam takes RMI observations of “Briones,” which is a channel on the crater rim, “La Serena,” some linear features in the crater wall, and a channel that feeds into the Peace Vallis fan.
After a week of fairly simple arm targets, the rover planners had a real challenge with this workspace. The rocks were mostly too small and too rough to brush, but we did find one spot after a lot of looking. We did DRT, APXS, and MAHLI on this spot, named “San Jose,” and also did MAHLI and APXS on another rock named “Malla Qullu.” This last drive of the week is about 15 meters (about 49 feet) following along a ridge and then driving onto a nearby one.

3 Min Read Inside NASA’s New Orion Mission Evaluation Room for Artemis II
As NASA’s Orion spacecraft is carrying crew around the Moon on the Artemis II mission, a team of expert engineers in the Mission Control Center at NASA’s Johnson Space Center in Houston will be meticulously monitoring the spacecraft along its journey. They’ll be operating from a new space in the mission control complex built to host the Orion Mission Evaluation Room (MER). Through the success of Orion and the Artemis missions, NASA will return humanity to the Moon and prepare to land an American on the surface of Mars.
Inside the Mission Evaluation Room, dozens of engineers will be monitoring the spacecraft and collecting data, while the flight control team located in mission control’s White Flight Control Room is simultaneously operating and sending commands to Orion during the flight. The flight control team will rely on the engineering expertise of the evaluation room to help with unexpected spacecraft behaviors that may arise during the mission and help analyze Orion’s performance data.
The new Orion Mission Evaluation Room inside the Mission Control Center at NASA’s Johnson Space Center in Houston.NASA/Rad Sinyak The Mission Evaluation Room team is made up of engineers from NASA, Lockheed Martin, ESA (European Space Agency), and Airbus who bring deep, expert knowledge of the spacecraft’s subsystems and functions to the mission. These functions are represented across 24 consoles, usually staffed by two engineers in their respective discipline, often hosting additional support personnel during planned dynamic phases of the mission or test objectives.
“The operations team is flying the spacecraft, but they are relying on the Mission Evaluation Room’s reachback engineering capability from the NASA, industry, and international Orion team that has designed, built, and tested this spacecraft.”
Trey PerrymAn
Lead for Orion Mission and Integration Systems at NASA Johnson
Perryman guides the Artemis II Orion mission evaluation room alongside Jen Madsen, deputy manager for Orion’s Avionics, Power, and Software.
With crew aboard, Orion will put more systems to the test, requiring more expertise to monitor new systems not previously flown. To support these needs, and safe, successful flights of Orion to the Moon, NASA officially opened the all-new facility in mission control to host the Orion Mission Evaluation Room on Aug. 15.
The Orion Mission Evaluation Room team works during an Artemis II mission simulation on Aug. 19, 2025, from the new space inside the Mission Control Center at NASA’s Johnson Space Center in Houston.NASA/Rad Sinyak During Artemis II, the evaluation room will operate in three daily shifts, beginning about 48 hours prior to liftoff. The room is staffed around the clock throughout the nearly 10 day mission, up until the spacecraft has been safely secured inside the U.S. Navy ship that will recover it after splashdown.
Another key function of the evaluation room is collecting and analyzing the large amount of data Orion will produce during the flight, which will help inform the room’s team on the spacecraft’s performance.
“Data collection is hugely significant,” Perryman said. “We’ll do an analysis and assessment of all the data we’ve collected, and compare it against what we were expecting from the spacecraft. While a lot of that data comparison will take place during the mission, we’ll also do deeper analysis after the mission is over to see what we learned.”

This includes various engineering support from different NASA centers, Lockheed Martin’s Integrated Test Lab, ESA’s European Space Research and Technology Center, and more.
“It’s been amazing to have helped design and build Orion from the beginning – and now, we’ll be able to see the culmination of all those years of work in this new Mission Evaluation Room."
Jen Madsen
Deputy Manager for Orion’s Avionics, Power, and Software
“We’ll see our spacecraft carrying our crew to the Moon on these screens and still be continuously learning about all of its capabilities,” said Madsen.
The Artemis II test flight will send NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen around the Moon and return them safely back home. This first crewed flight under NASA’s Artemis campaign will set the stage for NASA to return Americans to the lunar surface and help the agency and its commercial and international partners prepare for future human missions to Mars.

On the night of Friday, May 16, something extraordinary lit up the skies over the American Southwest. A brilliant, fast-moving streak of light that captivated onlookers from Arizona to Colorado.
Witnesses in towns such as Safford, Fountain Hills, and Payson, as well as regions of New Mexico and Colorado, were left asking the same question: What exactly did we just see?
Speculation spread rapidly. Some suggested a Chinese rocket launch earlier that day could be responsible, possibly placing satellites into orbit. Others floated more exotic theories: perhaps STEVE, a rare atmospheric light phenomenon similar to the aurora borealis, or even a “light pillar,” formed when light reflects off high-altitude ice crystals.
Attempts to reach officials at Luke Air Force Base near Phoenix, Davis-Monthan Air Force Base in southern Arizona, and Kirtland Air Force Base in Albuquerque have so far yielded no response.
What if it wasn’t a rocket plume from a Chinese launch at all? What if something entirely different passed near our planet, like a comet or UFO, or perhaps it was a test of a space-based weapon or a directed-energy system?
Whatever it may have been, it remains a strange phenomenon, leaving many to wonder what truly streaked across the sky.

In a groundbreaking development, advances in quantum data analysis have led to a discovery no scientist could have foreseen. NASA’s deep space monitoring system, upgraded with a quantum processor designed to filter cosmic noise and decode interstellar signals, produced something startling: an image.
A conceptual interpretation of the Voyager 1 image.
But this wasn’t an input, a simulation, or a product of algorithmic imagination. It wasn’t the result of random noise or a misfired pattern recognition process. The quantum system returned a coherent, structured, and symmetrical image, undeniably artificial. And the data it derived from? None other than Voyager 1.
Renowned physicist Michio Kaku addressed the anomaly in a recent interview: “We may be witnessing the first whisper of a new intelligence, something not man-made, not terrestrial, and certainly not random.”
The image, reconstructed via entangled qubit networks, depicted a figure: humanoid in silhouette, yet composed of geometric segments that defied any known biological or mechanical blueprint. It seemed deliberately crafted to challenge human comprehension, alien, yet eerily familiar enough to spark recognition.
Not long ago, NASA pushed the boundaries of computation by launching an experimental quantum computer, capable of processing vast, multidimensional data streams. But after this revelation, NASA abruptly shut down the system following the unexpected and unsettling incident, in 2023, though some believe the research continued in secret.
Meanwhile, Voyager 1—the most distant human-made object in space, still traveling beyond our solar system after 45 years—has been transmitting strange, inexplicable data. According to NASA engineers, the spacecraft’s Attitude Articulation and Control System (AACS) began sending signals that “do not reflect what’s actually happening onboard.”
Instead of useful telemetry, Voyager 1 has been broadcasting a puzzling sequence: a repeating pattern of ones and zeros. Initially dismissed as a glitch, engineers traced the anomaly to the Flight Data Subsystem (FDS), pinpointing a malfunctioning chip. Yet, despite their efforts, the signal persisted, a digital enigma from 24 billion kilometers away.
Is this merely a failing system showing its age? Or is something, or someone, intentionally altering the data?
What if this “error” is a message? And if so, who’s sending it?
