Curiosity Blog, Sols 4961-4967: Approaching a Break in the Rock Record?

A black and white image taken from the deck of the Curiosity rover on Mars, looking out over a desolate, rocky landscape. In the foreground, parts of the rover's hardware, including mechanical joints, structural panels, and a dark strut bearing the 'JPL' logo, are visible. The middle ground features relatively flat terrain covered in dusty soil, dotted with light-colored, exposed rock plates and shallow depressions. In the background, rolling hills or mountains rise, displaying distinct, horizontal sedimentary layers against a clear, featureless sky.
NASA’s Mars rover Curiosity acquired this image showing distant light-colored rocks sitting directly underneath dark-colored rocks, a possible “erosional supersurface” — a geologic term that describes places where layers of sediment have been stripped away by wind or water at a regional scale before newer layers are deposited atop them, marking a break in the rock record. Curiosity captured the image using its Left Navigation Camera on July 23, 2026 — Sol 4963, or Martian day 4,963 of the Mars Science Laboratory mission — at 15:53:13 UTC.

Earth planning date: Friday, July 24, 2026

Curiosity spent the week continuing to climb her way up through the layers of Mount Sharp, exploring the sedimentary rock strip chart of Martian history. The rover has reached a layer where the science team had spotted a possible “erosional supersurface” by analyzing orbital data alongside images of the layers in the buttes above us. “Erosional supersurface” is a geologic term that describes places where layers of sediment have been stripped away by wind or water at a regional scale before newer layers are deposited atop them. These surfaces are common in wind-blown sand (aeolian) deposits, and they mark a break in the rock record. After eyeing this unusual section of Mount Sharp for the last few months, it’s exciting to finally be so close to this feature. Curiosity’s science instruments will give us the geologist’s-eye view of this region that we need to really understand this feature, including its composition and centimeter-scale geometry.

Our two plans this week focused on imaging the possible supersurface from a few different locations. This past weekend we backed away from the feature to get a good rover’s-eye view of the feature, which set us up nicely on Monday to collect two massive Mastcam mosaics across the entire layer. ChemCam provided additional support by collecting some long-distance RMI images of the most interesting areas of the supersurface. We also took the time to measure the composition of rocks at the bottom of this surface with a MAHLI and APXS target named “Monte Darwin” and ChemCam LIBS targets named “Patacamaya,” “Tarucachi,” and “Mojoncasa.”

Monday’s drive took us closer to the supersurface, while taking some MAHLI and Mastcam images of our wheels along the way, and the drive we planned today will bring us right up to the base of the layer. The science team was able to use Monday’s image to pick the most scientifically interesting spot to cross this surface, while also juggling constraints made by the reality of where we can drive our rather large rover — there’s some pretty sandy and steeply sloping terrain around here, so we also found a spot that looks like it’ll be one of the easier areas to traverse. Hopefully next week we’ll go up and over the supersurface — stay tuned.

NASA’s Roman Telescope to Carry 1.35 Million Names to Deep Space

2026-07-31 14:11

People in blue protective suits and a red cherry picker work in an industrial high bay.

On July 27, technicians at NASA’s Kennedy Space Center in Florida installed a memory card containing 1,350,144 names as part of a commemorative plaque on the Nancy Grace Roman Space Telescope. The names were submitted by people globally, including astronauts from Artemis II and Artemis III. The memory card will travel with the Roman observatory to the Sun-Earth Lagrange point 2, or L2, about one million miles from Earth, where the Sun’s and Earth’s gravity balance out.

Roman is named after Dr. Nancy Grace Roman, NASA’s first chief astronomer and one of the architects of the agency’s modern science program. Roman championed space-based observatories that could study the universe from above Earth’s hazy atmosphere while making their data broadly available to the scientific community.

NASA and SpaceX are targeting launch for no earlier than 7:26 a.m. EDT Sunday, Aug. 30 aboard a SpaceX Falcon Heavy from Launch Complex 39A at Kennedy.

Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

A telescopic image of a dark nebula.

NGC 4372 and the Dark Doodad

Explanation: The Dark Doodad Nebula drifts through southern skies, a tantalizing target for binoculars toward the small constellation Musca, The Fly. A dusty interstellar cloud, it’s seen against rich starfields just south of the Coalsack Nebula and the Southern Cross. Stretching for about 3 degrees across this telescopic field of view, the Dark Doodad is punctuated near its southern tip (upper right) by yellowish globular star cluster NGC 4372. Of course NGC 4372 roams the halo of our Milky Way galaxy, a background object some 20,000 light-years away and only by chance along our line-of-sight to the Dark Doodad. About 700 light-years distant and over 30 light-years long, the Dark Doodad’s well defined silhouette belongs to the potentially star-forming Musca molecular cloud. The dusty Dark Doodad’s delightfully alliterative moniker was first coined by astro-imager and writer Dennis di Cicco in 1986 while observing Comet Halley from the Australian outback.

Destructive Fires Char Western Europe

2026-07-31 04:01

A brown patch of burned vegetation is visible on the landscape surrounding two reservoirs in a hilly region west of Madrid.
Charred landscapes surround reservoirs in central Spain in an image captured by the OLI (Operational Land Imager) on Landsat 9 on July 29, 2026. The false-color image combines observations at visible, near-infrared, and shortwave-infrared wavelengths (bands 6-5-3), making it easier to distinguish brown burned vegetation from green unburned vegetation.

Wildland fires occur across Europe every summer, but those that erupted in Spain and France in July 2026 were among the largest and most disruptive the two countries have faced in decades. Some of the most consequential fires emerged in southwestern France’s Gironde Department and Spain’s Ávila and Madrid provinces in mid-July, where blazes forced hundreds of thousands of people to evacuate and destroyed hundreds of homes.

Government officials in Spain say that a fire in Ávila, after charring around 50,000 hectares (124,000 acres), is the largest on record, surpassing a blaze that burned in Larouco, Quiroga, and Oencia in 2025. NASA satellites first observed signs of the Ávila fire burning near Burgohondo on July 22 and July 23. By July 24, it had merged with fires in neighboring provinces, pushing the total area burned to 77,000 hectares, an area about the size of New York City.

The image above, captured by Landsat 9, shows charred landscapes around Burgohondo on July 29, 2026. In the false-color image, unburned vegetation appears light green, and burned areas appear brown. The two reservoirs in the center of the image were heavily affected. Flames tore through homes, restaurants, campgrounds, marinas, and other infrastructure surrounding the reservoirs, according to news reports.

A similar crisis unfolded in southwestern France, west of Bordeaux. One of the largest fires to burn in France this decade charred more than 42,000 hectares, prompting large-scale evacuations and devastating the village of Le Porge. As of late July, fires had burned more than 90,000 hectares across France, more than any other season in decades, according to data from the European Forest Fire Information System.

Environmental conditions months before the fires ignited made the landscape in both Spain and France particularly susceptible to burning, according to an analysis conducted by researchers with The State of Wildfires Project. Unusually wet winter weather enhanced vegetation growth in grasslands, shrublands, and forest understories, and then a series of sweltering heat waves and a period of drought parched the vegetation and primed it to burn. Several days of strong winds reaching 65 kilometers (40 miles) per hour at times served as the final trigger, the researchers found, fanning flames and encouraging rapid spread.

On July 25, conditions at fires in southwestern France grew so intense that French firefighters reported the formation of a pyrocumulonimbus—a towering type of “fire cloud” that draws convective energy from the heat of the fires. An international group of atmospheric scientists and fire experts who track the unusual clouds has documented the occasional formation of the clouds in Spain and Portugal in recent decades, but members of the group note that this is the first report of a fire in France producing one.

Thousands of firefighters and military personnel have battled fires in both countries. Crews have used aircraft to attack the fires with water and flame retardant, while teams on the ground have constructed firebreaks using tools ranging from bulldozers to hand tools. Firefighters gained the advantage by late July, allowing authorities to start lifting evacuation orders. However, forecasters are warning that the risk of fire in the coming days remains high due to the persistence of hot, dry conditions.

Government satellite data are part of a global system of observations used to track fire behavior and analyze emerging trends. Among the real-time wildfire monitoring tools that NASA makes available are FIRMS (Fire Information for Resource Management System) and the Worldview browser.

Students Take on Airborne Field Research with NASA

The gusty wind didn’t make it easy to hold tight to a balloon so large. The balloon, a scientific instrument called an ozonesonde, was about to be released into the atmosphere above the Texas Gulf Coast by students from NASA’s SARP (Student Airborne Research Program), which concluded its summer session July 27. The balloon’s job was to measure ozone concentrations as it rose through the atmosphere.

The center of the image shows a large white balloon. Beneath the balloon are five people in a circle, gently holding at the bottom of the balloon to keep it upright. In the background of the image, other people watch.

A dozen of the 48 undergraduate students participated in atmospheric field research. Guided by instrument scientists, university professors, and graduate students, the SARP students prepared the ozonesondes for takeoff. They chemically treated instrument cells attached to the sensor, wrangled the balloons during inflation, and finally, released them into the sky. As the balloons flew, the students monitored the data.

“This research program is a unique experience for students where they have the opportunity to see the different careers related to Earth system science,” said Yaitza Luna-Cruz, program manager for NASA’s Early Career Research Program at NASA Headquarters in Washington.

Each student was assigned to one of four disciplines: atmospheric science, oceans, terrestrial ecology, or hydrology. They gathered field data, designed individual research projects, and presented their findings at the end of the program. When possible, they cross-checked their measurements with NASA satellite missions.

SARP students and instrument scientists walk away from NASA’s G-V aircraft after their science flight. “If you ever have the opportunity to participate in SARP, I would recommend that you do it,” said Darriqa Jones, marine and environmental science student at Hampton University in Hampton, Virginia. “It’s a once in a lifetime experience.”

“This is such an awesome experience,” said Marin Stevens, a chemistry student from the University of Colorado at Colorado Springs, minutes after she released the ozonesonde into the atmosphere. “It’s way beyond what I would have expected.”

Airborne science was a highlight of the program. Five science aircraft supported the program this year, including NASA’s Gulfstream G-III, GV, and C-20A, Dynamic Aviation’s B200, and a P-III from the National Oceanic and Atmospheric Administration. Students worked alongside scientists operating various instruments, such as a laser designed to collect measurements on particulates in the atmosphere.

For many students, their time in Houston was their first foray into field research, and, like the students releasing the balloons, they were eager to continue to learn and experience hands-on science. After the first two weeks, the cohort split into two, with half of the students traveling to California and half to Virginia to continue their research.

Four students in green jumpsuits kneel on a concrete runway. The woman on the left is in a backbend, in the shape of the letter ‘n’. The student second from the left is kneeling with his hands above him, in the shape of the letter ‘A’. The student second from the right is kneeling sideways with her arms curled over her head, in the shape of the letter ‘S’. The student on the right is kneeling with her hands above her, in the shape of the letter ‘A’. In the background, an aircraft is seen on the runway.

“The coolest part of SARP is the passion everyone has,” said Joelle Hopkins, SARP project manager, NASA Headquarters. “It’s so enjoyable to work with scientists, faculty, and graduate mentors who are passionate about the science, sharing the science with the students, and building the next generation of scientists.”

The annual eight-week program enhances what students are learning in the classroom by giving them hands-on field experience. It is designed to be a steppingstone into a career in field research or other STEM fields. Students participate in all aspects of a scientific campaign, including data collection, data analysis, and research. They attend science lectures and workshops, join research flights, and accompany scientists into the field.
