Perseverance Finds Popcorn on Planet Mars

A jumbled field of light toned rocks with unusual ‘popcorn’-like textures and abundant mineral veins.
Mars Perseverance Sol 1175 – Right Mastcam-Z Camera: A jumbled field of light toned rocks with unusual ‘popcorn’-like textures and abundant mineral veins. NASA’s Mars Perseverance rover acquired this image using its Right Mastcam-Z camera. Mastcam-Z is a pair of cameras located high on the rover’s mast. This image was acquired on June 10, 2024 (Sol 1175) at the local mean solar time of 14:04:57.

After months of driving, Perseverance has finally arrived at ‘Bright Angel’, discovering oddly textured rock unlike any the rover has seen before. The team now plans to drive up the slope to uncover the origin of this rock sequence and its relationship to the margin unit.

Having completed a survey of the intriguing and diverse boulders at ‘Mount Washburn,’ the rover headed north, parking just in front of an exposure of layered light toned rock. This provided the team with our first close-up look of the rocks that make up the ‘Bright Angel’ exposure, so Perseverance stopped to acquire images, before driving west to a larger and more accessible outcrop where the rover will conduct detailed exploration.

Perseverance arrived at the base of this outcrop on sol 1175, and geologists on the science team were mesmerized by the strange textures of the light toned rocks found there. These rocks are filled with sharp ridges that resemble the mineral veins found at the base of the fan, but there appears to be more of them here. Additionally, some rocks are densely packed with small spheres, and we’ve jokingly referred to this as a ‘popcorn’-like texture. Together, these features suggest that groundwater flowed through these rocks after they were laid down. Next, Perseverance will gradually ascend up the rock exposure, taking measurements as it goes. Over the weekend, the abrasion tool will be used to take a close-up look and acquire detailed chemical information using the instruments on the rover’s arm. With this data in hand, the team will decide whether or not to sample. Once our exploration at ‘Bright Angel’ is complete, we will drive south back across Neretva Vallis and explore a site called ‘Serpentine Rapids’.

      National Institute of Aerospace NASA is calling on the next generation of collegiate innovators to imagine bold new concepts l pushing the boundaries of human exploration on the Moon, Mars, and beyond through the agency’s 2026 NASA Revolutionary Aerospace Systems Concepts – Academic Linkage (RASC-AL) competition.  
      The RASC-AL challenge fuels innovation for aerospace systems concepts, analogs, and technology prototyping by bridging gaps through university engagement with NASA and industry. The competition is seeking U.S.-based undergraduate and graduate-level teams and their faculty advisors to develop new concepts to improve our ability to operate on the Moon and Mars. This year’s themes range from developing systems and technologies to support exploration of the lunar surface, to enhancing humanity’s ability to operate and return data from the surface of Mars.  
      “This competition is a unique opportunity for university students to play a role in the future of space innovation,” said Dan Mazanek, assistant branch head of NASA’s Exploration Space Mission Analysis Branch at NASA’s Langley Research Center in Hampton Virginia. “The RASC-AL challenge fuels creativity and empowers students to explore what’s possible. We’re excited for another year of RASC-AL and fresh ideas coming our way.”  
      Interested and eligible teams are invited to propose groundbreaking solutions and systems approaches that redefine how humans live and explore in deep space with relation to one of the following themes:  
      Communications, Positioning, Navigation, and Timing Architectures for Mars Surface Operations  Lunar Surface Power and Power Management and Distribution Architectures   Lunar Sample Return Concept  Lunar Technology Demonstrations Leveraging Common Infrastructure   Teams should express their intent to participate by submitting a non-binding notice of intent by Monday Oct. 13. Teams who submit a notice will be invited to a question-and-answer session with NASA subject matter experts on Monday Oct. 27.  
      The proposals, due Monday Feb. 23, 2026, are required to be seven-to-nine pages with an accompanying two-to-three-minute video. Proposals should demonstrate innovative solutions with original engineering and analysis in response to one of the four 2026 RASC-AL themes. Each team’s response should address novel and robust technologies, capabilities, and operational models that support expanding human’s ability to thrive beyond Earth. 
      Based on review of the team proposal and video submissions, in March, up to 14 teams will be selected to advance to the final phase of the competition – writing a technical paper, creating a technical poster, and presenting their concepts to a panel of NASA and industry experts in a competitive design review at the 2026 RASC-AL Forum in Cocoa Beach, Florida, beginning Monday June 1, 2026. 
      “The RASC-AL challenge enables students to think like NASA engineers—and in doing so, they often become the engineers who will carry NASA forward,” said Dr. Christopher Jones, RASC-AL program sponsor and Chief Technologist for the Systems Analysis and Concepts Directorate at NASA Langley. “The concepts they develop for this year’s competition will help inform our future strategies.”  
      Each finalist team will receive a $7,000 stipend to facilitate their full participation in the 2026 RASC-AL competition, and the top two overall winning teams will each be awarded an additional $7,000 cash prize as well as an invitation to attend and present their concept at an aerospace conference later in 2026. 
      The 2026 NASA RASC-AL competition is administered by the National Institute of Aerospace on behalf of NASA. The RASC-AL competition is sponsored by the agency’s Strategy and Architecture Office in the Exploration Systems Development Mission Directorate at NASA Headquarters, the Space Technology Mission Directorate (STMD), and the Systems Analysis and Concepts Directorate at NASA Langley. The NASA Tournament Lab, part of the Prizes, Challenges, and Crowdsourcing Program in STMD, manages the challenge.

      This artist’s concept shows what a gas giant orbiting Alpha Centauri A could look like.

      Artwork: NASA, ESA, CSA, STScI, R. Hurt (Caltech/IPAC) Astronomers using NASA’s James Webb Space Telescope have found strong evidence of a giant planet orbiting a star in the stellar system closest to our own Sun. At just 4 light-years away from Earth, the Alpha Centauri triple star system has long been a compelling target in the search for worlds beyond our solar system.
      Visible only from Earth’s Southern hemisphere, it’s made up of the binary Alpha Centauri A and Alpha Centauri B, both Sun-like stars, and the faint red dwarf star Proxima Centauri. Alpha Centauri A is the third brightest star in the night sky. While there are three confirmed planets orbiting Proxima Centauri, the presence of other worlds surrounding Alpha Centauri A and Alpha Centauri B has proved challenging to confirm.
      Now, Webb’s observations from its Mid-Infrared Instrument (MIRI) are providing the strongest evidence to date of a gas giant orbiting Alpha Centauri A. The results have been accepted in a series of two papers in The Astrophysical Journal Letters.
      If confirmed, the planet would be the closest to Earth that orbits in the habitable zone of a Sun-like star. However, because the planet candidate is a gas giant, scientists say it would not support life as we know it.
      “With this system being so close to us, any exoplanets found would offer our best opportunity to collect data on planetary systems other than our own. Yet, these are incredibly challenging observations to make, even with the world’s most powerful space telescope, because these stars are so bright, close, and move across the sky quickly,” said Charles Beichman, NASA’s Jet Propulsion Laboratory and the NASA Exoplanet Science Institute at Caltech’s IPAC astronomy center, co-first author on the new papers. “Webb was designed and optimized to find the most distant galaxies in the universe. The operations team at the Space Telescope Science Institute had to come up with a custom observing sequence just for this target, and their extra effort paid off spectacularly.”
      Image A: Alpha Centauri 3 Panel (DSS, Hubble, Webb)
      This image shows the Alpha Centauri star system from several different ground- and space-based observatories: the Digitized Sky Survey (DSS), NASA’s Hubble Space Telescope, and NASA’s James Webb Space Telescope. Alpha Centauri A is the third brightest star in the night sky, and the closest Sun-like star to Earth. The ground-based image from DSS shows the triple system as a single source of light, while Hubble resolves the two Sun-like stars in the system, Alpha Centauri A and Alpha Centauri B. The image from Webb’s MIRI (Mid-Infrared Instrument), which uses a coronagraphic mask to block the bright glare from Alpha Centauri A, reveals a potential planet orbiting the star. Science: NASA, ESA, CSA, STScI, DSS, A. Sanghi (Caltech), C. Beichman (NExScI, NASA/JPL-Caltech), D. Mawet (Caltech); Image Processing: J. DePasquale (STScI) Several rounds of meticulously planned observations by Webb, careful analysis by the research team, and extensive computer modeling helped determine that the source seen in Webb’s image is likely to be a planet, and not a background object (like a galaxy), foreground object (a passing asteroid), or other detector or image artifact.
      The first observations of the system took place in August 2024, using the coronagraphic mask aboard MIRI to block Alpha Centauri A’s light. While extra brightness from the nearby companion star Alpha Centauri B complicated the analysis, the team was able to subtract out the light from both stars to reveal an object over 10,000 times fainter than Alpha Centauri A, separated from the star by about two times the distance between the Sun and Earth.
      Image B: Alpha Centauri 3 Panel (Webb MIRI Image Detail)
      This three-panel image captures NASA’s James Webb Space Telescope’s observational search for a planet around the nearest Sun-like star, Alpha Centauri A. The initial image shows the bright glare of Alpha Centauri A and Alpha Centauri B, and the middle panel then shows the system with a coronagraphic mask placed over Alpha Centauri A to block its bright glare. However, the way the light bends around the edges of the coronagraph creates ripples of light in the surrounding space. The telescope’s optics (its mirrors and support structures) cause some light to interfere with itself, producing circular and spoke-like patterns. These complex light patterns, along with light from the nearby Alpha Centauri B, make it incredibly difficult to spot faint planets. In the panel at the right, astronomers have subtracted the known patterns (using reference images and algorithms) to clean up the image and reveal faint sources like the candidate planet. Science: NASA, ESA, CSA, STScI, A. Sanghi (Caltech), C. Beichman (NExScI, NASA/JPL-Caltech), D. Mawet (Caltech); Image Processing: J. DePasquale (STScI) While the initial detection was exciting, the research team needed more data to come to a firm conclusion. However, additional observations of the system in February 2025 and April 2025 (using Director’s Discretionary Time) did not reveal any objects like the one identified in August 2024.
      “We are faced with the case of a disappearing planet! To investigate this mystery, we used computer models to simulate millions of potential orbits, incorporating the knowledge gained when we saw the planet, as well as when we did not,” said PhD student Aniket Sanghi of Caltech in Pasadena, California. Sanghi is a co-first author on the two papers covering the team’s research.
      In these simulations, the team took into account both a 2019 sighting of the potential exoplanet candidate by the European Southern Observatory’s Very Large Telescope, the new data from Webb, and considered orbits that would be gravitationally stable in the presence of Alpha Centauri B, meaning the planet wouldn’t get flung out of the system.
      Researchers say a non-detection in the second and third round of observations with Webb isn’t surprising.
      “We found that in half of the possible orbits simulated, the planet moved too close to the star and wouldn’t have been visible to Webb in both February and April 2025,” said Sanghi.
      Image C: Alpha Centauri A Planet Candidate (Artist’s Concept)
      This artist’s concept shows what a gas giant orbiting Alpha Centauri A could look like. Observations of the triple star system Alpha Centauri using NASA’s James Webb Space Telescope indicate the potential gas giant, about the mass of Saturn, orbiting the star by about two times the distance between the Sun and Earth. In this concept, Alpha Centauri A is depicted at the upper left of the planet, while the other Sun-like star in the system, Alpha Centauri B, is at the upper right. Our Sun is shown as a small dot of light between those two stars. Artwork: NASA, ESA, CSA, STScI, R. Hurt (Caltech/IPAC) Based on the brightness of the planet in the mid-infrared observations and the orbit simulations, researchers say it could be a gas giant approximately the mass of Saturn orbiting Alpha Centauri A in an elliptical path varying between 1 to 2 times the distance between Sun and Earth.
      “If confirmed, the potential planet seen in the Webb image of Alpha Centauri A would mark a new milestone for exoplanet imaging efforts,” Sanghi says. “Of all the directly imaged planets, this would be the closest to its star seen so far. It’s also the most similar in temperature and age to the giant planets in our solar system, and nearest to our home, Earth,” he says. “Its very existence in a system of two closely separated stars would challenge our understanding of how planets form, survive, and evolve in chaotic environments.”
      If confirmed by additional observations, the team’s results could transform the future of exoplanet science.
      “This would become a touchstone object for exoplanet science, with multiple opportunities for detailed characterization by Webb and other observatories,” said Beichman.
      For example, NASA’s Nancy Grace Roman Space Telescope, set to launch by May 2027 and potentially as early as fall 2026, is equipped with dedicated hardware that will test new technologies to observe binary systems like Alpha Centauri in search of other worlds. Roman’s visible light data would complement Webb’s infrared observations, yielding unique insights on the size and reflectivity of the planet.
      The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

      Captured at a location called “Falbreen,” this enhanced-color mosaic features decep-tively blue skies and the 43rd rock abrasion (the white patch at center-left) of the NASA Perseverance rover’s mission at Mars. The 96 images stitched together to create this 360-degree view were acquired May 26, 2025.NASA/JPL-Caltech/ASU/MSSS In this natural-color version of the “Falbreen” panorama, colors have not been enhanced and the sky appears more reddish. Visible still is Perseverance’s 43rd rock abrasion (the white patch at center-left). The 96 images stitched together to create this 360-degree view were acquired May 26, 2025.NASA/JPL-Caltech/ASU/MSSS ‘Float rocks,’ sand ripples, and vast distances are among the sights to see in the latest high-resolution panorama by the six-wheeled scientist.
      The imaging team of NASA’s Perseverance Mars rover took advantage of clear skies on the Red Planet to capture one of the sharpest panoramas of its mission so far. Visible in the mosaic, which was stitched together from 96 images taken at a location the science team calls “Falbreen,” are a rock that appears to lie on top of a sand ripple, a boundary line between two geologic units, and hills as distant as 40 miles (65 kilometers) away. The enhanced-color version shows the Martian sky to be remarkably clear and deceptively blue, while in the natural-color version, it’s reddish.
      “Our bold push for human space exploration will send astronauts back to the Moon,” said Sean Duffy, acting NASA administrator. “Stunning vistas like that of Falbreen, captured by our Perseverance rover, are just a glimpse of what we’ll soon witness with our own eyes. NASA’s groundbreaking missions, starting with Artemis, will propel our unstoppable journey to take human space exploration to the Martian surface. NASA is continuing to get bolder and stronger.”
      The rover’s Mastcam-Z instrument captured the images on May 26, 2025, the 1,516th Martian day, or sol, of Perseverance’s mission, which began in February 2021 on the floor of Jezero Crater. Perseverance reached the top of the crater rim late last year.
      “The relatively dust-free skies provide a clear view of the surrounding terrain,” said Jim Bell, Mastcam-Z’s principal investigator at Arizona State University in Tempe. “And in this particular mosaic, we have enhanced the color contrast, which accentuates the differences in the terrain and sky.”
      Buoyant Boulder
      One detail that caught the science team’s attention is a large rock that appears to sit atop a dark, crescent-shaped sand ripple to the right of the mosaic’s center, about 14 feet (4.4 meters) from the rover. Geologists call this type of rock a “float rock” because it was more than likely formed someplace else and transported to its current location. Whether this one arrived by a landslide, water, or wind is unknown, but the science team suspects it got here before the sand ripple formed.
      The bright white circle just left of center and near the bottom of the image is an abrasion patch. This is the 43rd rock Perseverance has abraded since it landed on Mars. Two inches (5 centimeters) wide, the shallow patch is made with the rover’s drill and enables the science team to see what’s beneath the weathered, dusty surface of a rock before deciding to drill a core sample that would be stored in one of the mission’s titanium sample tubes.
      The rover made this abrasion on May 22 and performed proximity science (a detailed analysis of Martian rocks and soil) with its arm-mounted instruments two days later. The science team wanted to learn about Falbreen because it’s situated within what may be some of the oldest terrain Perseverance has ever explored — perhaps even older than Jezero Crater.
      Tracks from the rover’s journey to the location can be seen toward the mosaic’s right edge. About 300 feet (90 meters) away, they veer to the left, disappearing from sight at a previous geologic stop the science team calls “Kenmore.”
      A little more than halfway up the mosaic, sweeping from one edge to the other, is the transition from lighter-toned to darker-toned rocks. This is the boundary line, or contact, between two geologic units. The flat, lighter-colored rocks nearer to the rover are rich in the mineral olivine, while the darker rocks farther away are believed to be much older clay-bearing rocks.
