Curiosity Blog, Sols 4636-4637: Up Against a Wall
NASA’s Mars rover Curiosity acquired this image, showing itself parked at the wall of a fracture named “Río Frío.” Curiosity used its Left Navigation Camera on Aug. 19, 2025 — Sol 4634, or Martian day 4,634 of the Mars Science Laboratory mission — at 14:51:33 UTC.

What does a good rover do when her back is up against a wall? Fight for science!
Curiosity indeed fought the good fight at “Río Frío,” the wall of one of the many ridges cutting through the boxwork terrain we have been systematically exploring. The observations along the wall today provide insight into the internal structure and chemistry of the ridges, hopefully giving us clues as to why they are standing proud relative to the surrounding terrain.
The structural story will be told by the large Mastcam mosaics we planned, covering the ridge from base to top, and from a MAHLI mosaic covering a horizon of the wall filled with resistant nodules and smooth, swooping surfaces cutting in all directions that are likely veins. The mosaic target, “Jardín de las Delicias,” will surely yield a surfeit of Martian delights. The chemical story will be told by APXS analysis of the nodule-filled target “Minimini” and SuperCam analysis of a vein at “El Tapado.” In contrast to the ridge itself, we planned a Mastcam mosaic of part of the hollow at the base of the ridge at target “Playa Zapatilla.”
Beyond the ridge, we planned Mastcam and ChemCam imaging of the “Paniri” and “Mishe Mokwa” buttes, respectively, and sky observations with Navcam and Mastcam. DAN, RAD, and REMS run periodically through the plan keeping their eye on the Martian environment. Our drive will take us to a smaller ridge perpendicular to Río Frío, where we will once again fight to learn the secrets these ridges have to tell about Mars’ past.

Curiosity Blog, Sols 4634-4635: A Waiting Game
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on Aug. 18, 2025 — Sol 4633, or Martian day 4,633 of the Mars Science Laboratory mission — at 12:39:47 UTC.

The downlink data from our weekend activities arrived on Earth as we started planning this morning. As the APXS payload uplink and downlink lead, I assess the downlink data to ensure that our observations executed and that the instrument is healthy before we can proceed with the day’s activities. We also need that downlink data to assess which targets we can safely touch with Curiosity’s arm, to place APXS and MAHLI to analyze chemistry and closeup textures, respectively, as well as target for Mastcam and ChemCam, and plan the next drive. Because of the relatively late downlink, we all waited patiently for the necessary data to be processed before we could really start to plan in earnest.
It is always exciting to see our new parking spot and the view in front of the rover. Today was no exception. The drive executed as planned and we are on stable ground, which will enable us to unstow the arm for contact science with APXS and MAHLI.
We selected a representative bedrock patch (“Gil”) that was large enough and smooth enough to brush for dust removal, and to place APXS and MAHLI on. ChemCam will also analyze this target with LIBS, and Mastcam will capture a documentation image. The bedrock at this location is representative of an intermediate zone between the large resistant ridges and hollows that comprise the boxwork terrain that we are currently exploring. Mastcam will image the wall of a prominent resistant ridge that we are driving to (“Río Frío”), as well as a narrow, sand-filled trough (“Cusi Cusi”). The remote long-distance imaging capabilities of ChemCam will be used to look at the base of the Mishe Mokwa butte, off to the east.
Observations to monitor the atmosphere are also planned before we drive away from this location. They include a Navcam large dust-devil survey and suprahorizon movie, and a Mastcam tau observation to observe dust in the atmosphere. After the touch (and targeted science) part of this touch-and-go plan, the drive (go part) should take us about 36 meters (about 118 feet) to the wall of Río Frío. (see associated image).
After the drive, we will document the ground beneath the rover’s wheels with MARDI before some untargeted science. Mastcam will again image Río Frío in early morning light, trying to highlight structures and veins that might be present, and ChemCam will utilize their autonomous targeting capabilities to analyze a bedrock target in our new workspace. Two more atmospheric observations are also squeezed in before we hand over to the next plan: a Navcam cloud-altitude observation and line-of-sight scan.
Standard REMS, DAN and RAD activities round out this jam-packed plan. The downlink was well worth the wait!

Today we uplinked a three-sol weekend plan with lots of exciting activities — to support both the science and engineering teams!
While usually our science activities take front and center stage, we often also do engineering maintenance activities as well to maintain the mechanisms and engineering health state of the rover. On Sol 4631, we planned a maintenance activity of our Battery Control Boards (BCBs) which are electronic control boards attached to the rover’s batteries and are what let us interact with the batteries as needed. This maintenance is done periodically to correct for any time drift on the BCBs, so we get as accurate of data as possible.
On this sol, we also did a dump of all of our parameters — these are essentially variables set onboard the rover which serve as inputs to a variety of functions. Occasionally we send a list of all these variables back down to the ground so we can verify they match as expected. We don’t want to have set a value and then forget about it!
We, of course, also did science activities on this sol. After completing our engineering activities, we started off with some remote science; this included Mastcam imaging and ChemCam measurements of several interesting targets. These were chosen in order to assess variability within the “Cerro Paranal” ridge within view, and to document any layering or fractures in the rock. We then completed several arm activities in order to get more information on these targets through the use of our APXS spectrometer.
On Sol 4632, we planned some remote atmospheric science, including a Navcam dust-devil survey, a Mastcam tau (measurement of the atmospheric opacity), APXS atmospheric observations, and more imaging of some of the ridge targets we looked at in the previous sol.
On Sol 4633, we continued with more science imaging, including a horizon movie using Navcam and a dust-devil movie, before proceeding into our drive. We planned a drive of about 19 meters (about 62 feet) to the south, along the eastern edge of Cerro Paranal. After the drive, it is then standard for us to take new imaging of our new location. We’re excited to get these science images back and to hear how the drive went when the team comes back on Monday!

NASA The Moon’s light is refracted by Earth’s atmosphere in this April 13, 2025, photograph from the International Space Station as it orbited into a sunset 264 miles above the border between Bolivia and Brazil in South America.
Understanding the Moon helps us understand other planets, how they have evolved and the processes which have shaped their surfaces. It also helps us understand the influence the Moon has had on Earth, the record of the ancient Sun, and it serves as a platform to study the rest of the universe. By using the Moon as our closest testing ground for robotics and instrument systems, we can further human exploration to not only the Moon, but the rest of the solar system.
Through Artemis missions, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars.

NASA’s X-59 quiet supersonic research aircraft sits on the ramp at Lockheed Martin Skunk Works in Palmdale, California during sunrise, shortly after completion of painting in December 2023.Credit: NASA/Steve Freeman As we observe National Aviation Day Tuesday – a tribute to Orville Wright’s birthday – let’s reflect on both America’s and NASA’s aviation heritage and share how we are pushing the boundaries of flight for the nation’s future. Modern NASA grew from the National Advisory Committee for Aeronautics (NACA), an agency created by Congress in 1915 to advance U.S. aviation. When President Eisenhower signed the National Aeronautics and Space Act of 1958, NACA was dissolved and its people, laboratories and research programs became the foundation of NASA. These intrepid men and women are the cornerstone of the world’s most capable aerospace industry and their legacy lives on today across all facets of the agency.
The most significant aviation milestones in the twentieth century were achieved through both NASA and NACA research and through the courage of pioneering test pilots. In 1947, the joint NACA/U.S. Army Air Forces (later the U.S. Air Force, or USAF) developed Bell X‑1 flew faster than the speed of sound, shattering the mythical “sound barrier.” This breakthrough, enabled by NACA wind-tunnel data and high-speed aerodynamic expertise, made supersonic flight a reality and led directly to NACA Test Pilot Scott Crossfield being the first human to reach Mach 2, twice the speed of sound, in the Douglass DD558-II a mere six years later. During the X‑15 program of the 1960s, legendary NASA Test Pilots Joe Walker, John McKay, Neil Armstrong, Milt Thompson, and Bill Dana piloted nearly half of the program’s sorties and flew the rocket-powered research plane at altitudes up to 354,200 feet and speeds of 4,520 mph (Mach 6.7).
The NASA/USAF-developed North American X‑15 became the world’s first reusable hypersonic aerospace vehicle, reaching space (above 50 miles altitude) on 11 separate missions; it provided essential data on materials, flight control and pilot physiology that helped shape the agency’s Mercury, Gemini, Apollo and Space Shuttle programs. These milestones remind us that our nation’s accomplishments are the result of visionary NASA, Department of Defense, industry engineers, and test pilots working together to achieve audacious goals.
NASA’s commitment to aviation innovation did not stop with early experimental high-speed aircraft. In the 1990s, the U.S. general aviation industry faced a steep decline – production fell from 18,000 aircraft in 1978 to fewer than 1,000 in 1993. NASA saw an opportunity: we envisioned a Small Aircraft Transportation System in which safe, efficient general aviation planes could revitalize a critical industry. To enable that vision, NASA partnered with the Federal Aviation Administration, industry, universities, and non‑profits to create the Advanced General Aviation Transport Experiments (AGATE) consortium in 1994. The AGATE consortium developed safer cockpit displays, crashworthiness improvements, efficient airfoils, and modern manufacturing techniques. These innovations transformed U.S. general aviation, helping spawn industry successes like the Cirrus SR20 and SR22 family of aircraft, which incorporate NASA-derived composite structures and safety features.
In 2004, NASA’s unmanned X‑43A Hyper-X broke world speed records for air‑breathing aircraft, flying at Mach 6.8 and later Mach 9.6. Those flights demonstrated practical scramjet propulsion and proved that hypersonic cruise flight is achievable.
Today, we are building on this legacy and pushing the envelope with the X-59. Later this year, NASA Test Pilot Nils Larson will usher in a new era of quiet supersonic flight when he pilots the X‑59 Quesst’s first flight out of NASA’s Armstrong Flight Research Center in Edwards, California. The experimental aircraft, designed to fly at 1.4 times the speed of sound while producing only a gentle sonic “thump” instead of the traditional loud sonic boom, will provide data vital to achieving the vision in President Donald J. Trump’s Executive Order “Leading the World in Supersonic Flight.”
Hypersonics research is another pillar to our 21st‑century vision. Lessons from the X‑15, X‑43, and Space Shuttle inform our study of high-temperature materials, flight controls and propulsion. These technologies will not only bolster national security but will also spur the development of ultrafast civil transports, shrinking the world even further. We are also investing in 21st century propulsion, additive manufacturing, and autonomy for light aircraft while also developing advanced air traffic control systems. Partnering with U.S. aerospace industry and the FAA, we will bring true 21st century technology into light general aviation aircraft, ensuring America remains at the forefront of aviation innovation.
I am continually inspired by the ingenuity of our past and the promise of our future. Our roots in NACA remind us that a small group of dedicated men and women can change the world. From the Wright brothers’ pioneering work to the supersonic and hypersonic records set by NASA pilots and vehicles, we have consistently expanded the boundaries of what is possible in flight. Looking ahead, our pursuit of quiet supersonic aircraft, hypersonic technologies, and revitalized general aviation will keep the U.S. aviation industry strong and sustainable for decades to come. On National Aviation Day, we celebrate not only our history but also the teamwork and vision that will carry us into the next century of flight.
Higher, Farther, Faster!
