Curiosity Blog, Sols 4577-4579: Watch the Skies
NASA’s Mars rover Curiosity acquired this image inside a trough in the boxwork terrain on Mars, using its Right Navigation Camera. Curiosity captured the image on June 20, 2025 — Sol 4575, or Martian day 4,575 of the Mars Science Laboratory mission — at 00:30:12 UTC. NASA/JPL-Caltech Written by Deborah Padgett, OPGS Task Lead at NASA’s Jet Propulsion Laboratory
Earth planning date: Friday, June 20, 2025
During the plan covering Sols 4575-4576, Curiosity continued our investigation of mysterious boxwork structures on the shoulders of Mount Sharp. After a successful 56-meter drive (about 184 feet), Curiosity is now parked in a trough cutting through a highly fractured region covered by linear features thought to be evidence of groundwater flow in the distant past of Mars. With all six wheels firmly planted on solid ground, our rover is ready for contact science! Unfortunately, a repeat of the frost-detection experiment expected for the weekend plan is postponed for a few days due to a well-understood ChemCam issue. In the meantime, our atmospheric investigations have a chance to shine, as they received additional time to observe the Martian sky.
In the early afternoon of Sol 4577, Curiosity’s navigation cameras will take a movie of the upper reaches of Aeolis Mons (Mount Sharp), hoping to see moving cloud shadows. This observation enables the team to calculate the altitude of clouds drifting over the peak. Next, Navcam will point straight up, to image cloud motion at the zenith and determine wind direction at their altitude. Mastcam will then do a series of small mosaics to study the rover workspace and features of the trough that Curiosity has entered. First is a 6×4 stereo mosaic of the workspace and the contact science targets “Copacabana” and “Copiapo.” The first target is a representative sample of the trough bedrock, and its name celebrates a town in Bolivia located on the shores of Lake Titicaca. The second target is a section of lighter-toned material, which may be associated with stripes or “veins” filling the many crosscutting fractures in the local stones. These are the deposits potentially left by groundwater intrusion long ago. The name “Copiapo” honors a silver mining city in the extremely dry Atacama desert of northern Chile. A second 6×3 Mastcam stereo mosaic will look at active cracks in the trough. Two additional 5×1 Mastcam stereo mosaics target “Ardamarca,” a ridge parallel to the trough walls, and a cliff exposing layers of rock at the base of “Mishe Mokwa” butte. At our current location, all the Curiosity target names are taken from the Uyuni geologic quadrangle named after the otherworldly lake bed and ephemeral lake high on the Bolivian altiplano, but the Mishe Mokwa butte is back in the Altadena quad, named for a popular hiking trail in the Santa Monica Mountains. After this lengthy science block, Curiosity will deploy its arm, brush the dust from Copacabana with the DRT, then image both it and Copiapo with the MAHLI microscopic imager. Overnight, APXS will determine the composition of these two targets.
Early in the morning of Sol 4578, Mastcam will take large 27×5 and 18×3 stereo mosaics of different parts of the trough, using morning light to highlight the terrain shadows. Later in the day, Navcam will do a 360 sky survey, determining phase function across the entire sky. A 25-meter drive (about 82 feet) will follow, and the post-drive imaging includes both a 360-degree Navcam panorama of our new location and an image of the ground under the rover with MARDI in the evening twilight. The next sol is all atmospheric science, with an extensive set of afternoon suprahorizon movies and a dust-devil survey for Navcam, as well as a Mastcam dust opacity observation. The final set of observations in this plan happens on the morning of Sol 4580 with more Navcam suprahorizon and zenith movies to observe clouds, a Navcam dust opacity measurement across Gale Crater, and a last Mastcam tau. On Monday, we expect to plan another drive and hope to return to the frost-detection experiment soon as we explore the boxwork canyons of Mars.

L. Y. Zhou, a senior at Skyline High School, Ann Arbor, MI, representing the SunRISE Ground Radio Lab (GRL) summer research project team at the Solar Heliospheric and INterplanetary Environment (SHINE) conference, held in Juneau, AK in August 2024. Other contributing high school students were S. Rajavelu-Mohan (Washtenaw Technical Middle College, Ann Arbor, MI), M. I. Costacamps-Rivera (Centro Residencial de Oportunidades Educativas de Mayagüez, Mayagüez, PR), E. Schneider (Marquette Senior High School, Marquette, MI), and L. Cui (Skyline High School, Ann Arbor, MI). Solar radio bursts, intense blasts of radio emission associated with solar flares, can wreak havoc on global navigation systems. Now, as part of the Ground Radio Lab campaign led by the University of Michigan and NASA’s SunRISE (Sun Radio Interferometer Space Experiment) mission, which is managed by the agency’s Jet Propulsion Laboratory in Southern California, high school and college students across the nation are collecting, processing, and analyzing space weather data to help better understand these bursts.
Participating students have presented their findings at local science fairs and national conferences, including the Solar Heliospheric and INterplanetary Environment (SHINE) conference held in Juneau, Alaska in August 2024. These students sifted through thousands of hours of observations to identify and categorize solar radio bursts.
Your school can get involved too!
Participating high schools receive free, self-paced online training modules sponsored by the SunRISE mission that cover a range of topics, including radio astronomy, space physics, and science data collection and analysis. Students and teachers participate in monthly webinars with space science and astronomy experts, build radio telescopes from kits, and then use these telescopes to observe low frequency emissions from the Sun and other objects like Jupiter and the Milky Way.
Visit the Ground Radio Lab website to learn more about the new campaign and apply to participate.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Boeing’s test plane simulates digital taxiing at Moffett Field at NASA’s Ames Research Center in California’s Silicon Valley. NASA/Brandon Torres Navarrete New technology tested by an industry partner at NASA’s Ames Research Center in California’s Silicon Valley could improve how commercial planes taxi to and from gates to runways, making operations safer and more efficient on the surfaces of airports.
Airport taxiways are busy. Planes come and go while support vehicles provide maintenance, carry fuel, transport luggage, and more. Pilots must listen carefully to air traffic control when getting directions to the runway – and garbled communications and heavy workloads can cause issues that could lead to runway incursions or collisions.
Researchers at Boeing are working to address these issues by digitizing taxiway information and automating aircraft taxi functions. The team traveled to NASA Ames to collaborate with researchers while testing their technology at the Moffett Federal Airfield and NASA’s FutureFlight Central, an air traffic control simulation facility.
Doug Christensen, test engineer for Air Traffic Management eXploration (ATM-X) at NASA Ames, and Mike Klein, autonomy technical leader in product development at Boeing discuss the digital taxi test in Ames’s FutureFlight Central facility.NASA/Brandon Torres Navarrete To test these new technologies, Boeing brought a custom single-engine test plane to the airfield. Working from FutureFlight Central, their researchers developed simulated taxiway instructions and deployed them to the test pilot’s digital tablet and the autonomous system.
Typically, taxiing requires verbal communication between an air traffic controller and a pilot. Boeing’s digital taxi release system displays visual turn-by-turn routes and directions directly on the pilot’s digital tablet.
“This project with Boeing lends credibility to the research being done across Ames,” said Adam Yingling, autonomy researcher for the Air Traffic Management-eXploration (ATM-X) program at NASA Ames. “We have a unique capability with our proximity to Moffett and the work Ames researchers are doing to advance air traffic capabilities and technologies to support the future of our national airspace that opens the door to work alongside commercial operators like Boeing.”
The team’s autonomous taxiing tests allowed its aircraft to follow the air traffic control’s digital instructions to transit to the runway without additional pilot inputs.
Estela Buchmann, David Shapiro, and Maxim Mounier, members of the NASA Ames ATM-X project team, analyze results of Boeing’s digital taxi test at Ames’s FutureFlight Central facility.NASA/Brandon Torres Navarrete As commercial air travel increases and airspace gets busier, pilots and air traffic controllers have to manage heavier workloads. NASA is working with commercial partners to address those challenges through initiatives like its Air Traffic Management-eXploration project, which aims to transform air traffic management to accommodate new vehicles and air transportation options.
“In order to increase the safety and efficiency of our airspace operations, NASA research in collaboration with industry can demonstrate how specific functions can be automated to chart the course for enhancing traffic management on the airport surface,” said Shivanjli Sharma, ATM-X project manager at Ames.
