Earth planning date: Friday, July 18, 2025
Curiosity has started to investigate the main exposure of the boxwork structures! What was once a distant target is now on our doorstep, and Curiosity is beginning to explore the ridges and hollows that make up this terrain, to better understand their chemistry, morphology, and sedimentary structures.
I was on shift as Long Term Planner during this three-sol weekend plan, and the team put together a very full set of activities to thoroughly investigate this site — from the sky to the sand. The plan starts with Navcam and Mastcam observations to assess the amount of dust in the atmosphere, followed by a large Mastcam mosaic to characterize the resistant ridge on which the rover is parked. ChemCam will also acquire a LIBS observation on a target named “Vicuna” to assess the chemistry of a well-exposed vein. The team chose this parking location to characterize the chemistry and textures of this topographic ridge (to compare with topographic lows), so the next part of the plan involves contact science using APXS and MAHLI to look at different parts of the nodular bedrock in our workspace, at targets named “Totoral” and “Sillar.” There’s also a MAHLI observation of the same vein that ChemCam targeted.
The second sol involves more Mastcam imaging to look at different parts of this prominent ridge, along with a ChemCam LIBS observation on top of the ridge, and a ChemCam RMI mosaic to document the sedimentary structures in a distant boxwork feature. Navcam will also be used to look for dust devils. Then Curiosity will take a short drive of about 5 meters (about 16 feet) to explore the adjacent hollow (seen as the low point in the foreground of the above Navcam image). After the drive we’ll take more images for context, and to prepare for targeting in Monday’s plan.
After all of this work it’s time to pause and take a deep breath… of Martian atmosphere. The weekend plan involves an exciting campaign to look for variations in atmospheric chemistry between night and day. So Curiosity will take an overnight APXS atmospheric observation at the same time that two instruments within SAM assess its chemical and isotopic abundance.
On the third sol Curiosity will acquire a ChemCam passive sky observation, leading to a great set of atmospheric data. These measurements will be compared to even more atmospheric activities in Monday’s plan to get the full picture. As you can imagine, this plan requires a lot of power, but it’s worth it for all of the exciting science that we can accomplish here.
The road ahead has many highs and lows (literally), but I can’t wait to see what Curiosity will accomplish. The distant buttes remind us that there’s so much more to explore, and I look forward to continuing to see where Curiosity will take us.

NASA/Carla Thomas NASA’s X-59 quiet supersonic research aircraft completed its first low-speed taxi test at U.S. Air Force Plant 42 in Palmdale, California, on July 10, 2025. This marked the first time the one-of-a-kind experimental aircraft has ever moved under its own power.
During the test, engineers and flight crews monitored the X-59 as it moved across the runway, working to validate critical systems like steering and braking. The taxiing represents the start of the X-59’s final series of ground tests before first flight.
The X-59 is the centerpiece of NASA’s Quesst mission, which aims to demonstrate quiet supersonic flight by reducing the loud sonic boom to a quieter “thump.”

These images captured by the Curiosity rover in 2014 reveals yet another unexplained aerial phenomenon in the Martian atmosphere, a cigar-shaped object with a consistent width and rounded ends.
What makes this anomaly particularly compelling is the sharp clarity of the image. According to Jean Ward the stars in the background appear crisp and unblurred, indicating that the object is not the result of motion blur or a long exposure. Notably, the object appears in five separate frames over an 8-minute span, suggesting it is moving relatively slowly through space, uncharacteristic of a meteorite entering the atmosphere. It also lacks the fiery tail typically associated with atmospheric entry.
Rather than a meteor, the object more closely resembles a solid, elongated craft of unknown origin. When oriented horizontally, it even appears to feature a front-facing structure, possibly a porthole or raised dome, hinting at a cockpit or command module.
Whether this object is orbiting beyond the visible horizon or connected to the surface far in the distance, its sheer size is unmistakable. Its presence raises compelling questions, could this be further evidence of intelligently controlled craft, whether of extraterrestrial or covert human origin, navigating through Martian airspace?View the full article

NASA/JPL-Caltech/ASU Arsia Mons, one of the Red Planet’s largest volcanoes, peeks through a blanket of water ice clouds in this image captured by NASA’s 2001 Mars Odyssey orbiter on May 2, 2025. Odyssey used a camera called the Thermal Emission Imaging System (THEMIS) to capture this view while studying the Martian atmosphere, which appears here as a greenish haze above the scene. A large crater known as a caldera, produced by massive volcanic explosions and collapse, is located at the summit. At 72 miles (120 kilometers) wide, the Arsia Mons summit caldera is larger than many volcanoes on Earth.
