NASA’s LRO Images Falcon 9 Crater on Moon, Learns New Details
This is an animated before-and-after view of the crater formed after a Falcon 9 upper stage struck the Moon’s surface on Aug. 5, 2026. These images were taken between Aug. 11 and 12 by the Narrow-Angle Camera on NASA’s Lunar Reconnaissance Orbiter. These images are enlarged three times from the original, with north facing up, and they cover an area about a quarter of a mile wide.

Between Aug. 11 and 12, NASA’s Lunar Reconnaissance Orbiter (LRO) captured a series of images of a new crater on the Moon. The crater formed on Aug. 5, when a SpaceX Falcon 9 upper stage impacted the surface following its January 2025 launch of the Firefly Blue Ghost 1 mission.
To capture imagery of the impact, engineers tilted the spacecraft so its cameras would point toward the crater each time LRO passed about 60 miles above the Moon, traveling 1 mile per second. The orbiter circles the Moon from pole to pole every two hours, while the Moon slowly rotates underneath it. To photograph a specific spot, the spacecraft must wait until that location turns into view, which took six days in this case.
Getting the pointing right was only half the challenge; timing had to be accurate as well. If the camera snapped even 10 seconds too early or too late, the target would drift off-center by 10 miles.

Because of the variety of viewing angles, scientists could see the crater under multiple lighting conditions that revealed unique features. In images where the crater rim stood out, scientists measured its 60‑foot width. Scientists also determined the crater is less than 10 feet deep based on the length of its shadow.
To capture these details, LRO used its Narrow-Angle Camera, which can spot features as small as 3 feet wide.
Collected between Aug. 11 and 12 by NASA’s Lunar Reconnaissance Orbiter, six days after a Falcon 9 upper-stage booster impacted the Moon, these images were taken from different viewing angles, bringing out different features. The darker area that fans around the crater in the upper-left image is rougher than the surroundings, as this surface material has been altered over a long time by solar wind, galactic cosmic rays, and micrometeorite impacts. The brighter rays and splotch above the crater in the lower-right image is fresher material that was excavated from deeper below the surface. The pictures are arranged in the order they were taken, starting at the top left and moving toward the bottom right, with the lighting angle from the Sun gradually changing from one image to the next. Each image is enlarged two times and shows an area of the Moon about 1,000 feet wide.

The images above show bright and dark rays stretching out from the crater. The darker streaks are made of surface dust and rocks altered over a long time by solar wind, galactic cosmic rays, and micrometeorite impacts. This weathered material was excavated by the collision from 1.5 feet into the lunar surface. The brighter streaks near the crater rim are made of fresh material excavated from deeper underground.
This image from NASA’s Lunar Reconnaissance Orbiter shows two oval regions where the Falcon 9 upper stage was likely to impact the Moon, based on calculations by engineers with NASA’s Center for Near Earth Object Studies. Both ellipses are 2.1 miles long and 0.4 miles wide. Both predictions use the same booster-trajectory calculations, but only the blue ellipse takes into account the lunar terrain. The red and blue dots show predicted impact locations, whereas the cyan dot shows the actual impact site.
NASA/JPL-Caltech
Finding the impact site took global coordination among experts and hobbyists. Independent astronomers first identified the rocket’s trajectory using publicly available data. NASA’s Center for Near Earth Object Studies, which tracks natural objects that could pose hazards to Earth for the agency’s Planetary Defense program, used this opportunity to test and validate tools and techniques for predicting impacts.
Based at NASA’s Jet Propulsion Laboratory in Southern California, the center incrementally refined the trajectory until identifying the location of impact, which it provided to the Republic of Korea for their Korea Pathfinder Lunar Orbiter (Danuri) team. The team used the high-resolution LUTI camera on Danuri a few hours later to image the crater, finding the prediction was accurate to about 0.6 miles.
After capturing images of the crater, the Danuri mission sent coordinates to NASA’s LRO team to help refine their follow-up imaging sequence. Comparing their new crater images with the pre-impact images, the LRO team updated the crater center coordinates: 19.4759°N, 266.7138°E, 511 meters elevation.

Human-Related Microbes May Survive Moon’s South Pole, NASA Finds

Some of Earth’s microbes likely to hitch a ride to space with human explorers could survive in the shaded nooks and crannies of the Moon’s South Pole region, NASA scientists say.
Published on Aug. 19, 2026, in Science Advances, these findings highlight a need to better understand microbial persistence in extreme lunar environments. As humans build a permanent presence on the Moon, it may become difficult to distinguish ancient lunar chemistry from contamination delivered by visiting astronauts. The concern extends beyond the Moon and on to Mars, scientists say.
“Humans are natural explorers, and with them come their voices, their memories … and their microbes,” said Prabal Saxena, a planetary scientist who led the study from NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “For some scientists, myself included, that reality can be unsettling. But it also creates an opportunity to turn an imperfect situation into a useful experiment.”
Bringing microbes along is unavoidable: Humans have, on average, 1 million bacteria living on each patch of skin the size of a pencil eraser, for example. These bacteria vent from spacesuits and habitats. Though the paper’s authors worry about contamination interfering with the search for chemical clues to ancient geology or biology, they also argue that the Moon should be used as a natural lab. In shaded areas around the South Pole, scientists could carefully test the real-life limits of microbial survival in an environment that can’t easily be reproduced on Earth.
The Apollo program landed six pairs of astronauts on the Moon between 1969 and 1972. All six landing sites are near the lunar equator. In this visualization, the Apollo sites are contrasted with the South Pole, an area with enormous potential for future exploration. Time passes as we zoom toward Shackleton crater at the South Pole, revealing illumination conditions quite different from those near the equator. While many craters remain in permanent shadow, some nearby mountains and ridges are in persistent sunshine, making them attractive candidates for solar power and long-term habitation.

Before any surface science can happen, scientists need a baseline measurement of what contaminants humans bring, the authors say.
“We need to understand what was there before us, because when we go to Mars to search for signs of life beyond our planet, we will want to make sure it’s not stuff we brought,” said Andrew Needham, a NASA Goddard-based paper co-author who is an Artemis contamination‑control scientist for lunar samples.
Even with strict sterilization procedures, some organisms are stubbornly resilient. A good example is Aspergillus niger, which is a fungus that thrives in warm, damp places like household bathrooms and heating, ventilation, and air conditioning systems. Astronauts have sampled it inside the International Space Station, and experiments demonstrate that the fungus can survive outside the station as well. Aspergillus niger was one of five microbes, including bacteria and fungi, selected for this study because of its known toughness in spaceflight environments.
That microbes survived on the space station’s exterior surprised scientists. These species are typically not considered “extremophiles” that can withstand harsh conditions, such as the vacuum of space, according to Aaron Regberg, a geomicrobiologist at NASA’s Johnson Space Center in Houston.
“I would have expected these microbes to have dried out,” said Regberg, who studies space station bacteria and was a co-author on the paper.

He pointed out that NASA often bakes robotic spacecraft at temperatures above 400 degrees Fahrenheit to reduce the number of living organisms on them. But that’s not possible with astronauts, so contamination concerns take on new meaning in crewed exploration of the Moon’s south polar environment.
A clearer picture of where microbes might survive comes from understanding how sunlight behaves at the poles. Survival in this study means the microbe can stay alive for at least one Earth day, which does not mean that it can grow and reproduce.
Because the Moon has a very small tilt on its axis, the view from its poles is of a Sun that appears to hover just above the horizon, skimming the surface like a flashlight laying on a table. As a result, elevated parts of the surface, including crater ridges, mountains, and even small bumps, block light from reaching low-lying terrain. This produces pockets of shadowed areas that can remain cold and preserve water, as well as shield fragile molecules and possible microorganisms from lethal radiation.
With that scientific context in mind, the team set out to test which Earth microbes could survive extreme polar conditions. They focused on organisms commonly found in spaceflight environments and those common on human skin. Besides Aspergillus niger, these included Bacillus subtilis, Staphylococcus aureus, Deinococcus radiodurans, and several species of Fusarium. Based on an analysis of previous studies, the scientists noted the maximum amount of heat and ultraviolet (UV) radiation each organism can withstand.
Then, the organisms were tested in simulations of three regions near the lunar South Pole — Nobile Rim, Connecting Ridge, and De Gerlache Rim. Those simulations used detailed environmental maps built from elevation and temperature data collected by instruments aboard NASA’s Lunar Reconnaissance Orbiter, combined with models of how radiation strikes the surface.
The models showed maps of “survivable niches” that range in size from a miles-wide crater floor to an astronaut’s boot print. Aspergillus niger, which was most resistant to UV radiation, was able to survive even in areas with some sunlight exposure. UV radiation is so deadly to most microbes that it’s used for sterilization in hospitals.
“When we think of the Moon, we don’t typically think of biology,” said Heather Graham, a paper co-author at NASA Goddard who helps develop tools and techniques for detecting biology that may look nothing like Earth’s. “But the Moon is a place where a cell can survive, so our first exploration of these sites should pay extra attention to our microbial hitchhikers and work hard to characterize lunar chemistry before our visits change what we will find.”
The authors note that while some microbes can survive in a dormant state in regions around the South Pole, and thereby confuse some future scientific investigations, there is no evidence the Moon has key ingredients to sustain growth and replication. Such ingredients include liquid water, which typically requires an atmosphere and moderate temperatures.

After nearly a decade of service to NASA, including an eight-month science expedition aboard the International Space Station, astronaut Jonny Kim’s last day at the agency is Thursday. He will continue serving as lieutenant commander in the U.S. Navy.
Kim launched to the space station in April 2025 aboard the Soyuz MS‑27 spacecraft to conduct scientific research as a flight engineer during Expeditions 72/73. During the mission, he orbited Earth 3,920 times, traveled nearly 104 million miles, and contributed to a broad range of scientific investigations spanning technology development, Earth science, biology, and human research critical for future exploration.
“Jonny Kim represents the very best of NASA, a person who continually pushed the boundaries of exploration while inspiring countless others,” said NASA Administrator Jared Isaacman. “His contributions aboard the International Space Station advanced critical science that will shape NASA’s future missions for decades to come. We are grateful for his dedication to our nation and to the pursuit of knowledge, and we wish him success as he continues his service in the U.S. Navy.”
Serving as the U.S. Operating Segment lead for the second half of Expedition 73, Kim oversaw operations across the station’s international modules. During the expedition, the station achieved a historic milestone when every available docking port was occupied for the first time in 25 years. He also commanded the Canadarm2 robotic arm during the first capture of Northrop Grumman’s new Cygnus XL spacecraft, securing 11,000 pounds of supplies for the station. Kim and his Roscosmos crewmates landed safely in Kazakhstan in December 2025.
“Jonny has been an integral part of the agency, and his immeasurable impact will be felt for generations to come,” said Vanessa Wyche, director of NASA’s Johnson Space Center in Houston. “From advancing groundbreaking science to inspiring the next generation, Jonny has been an incredible source of inspiration to our nation. His exceptional talent, determination, and grit will leave a lasting legacy at NASA.”
Kim was selected as a NASA astronaut in 2017 and completed two years of astronaut candidate training, which included instruction in space station systems, Russian language, robotics, T‑38 flight operations, geology, survival training, and spacewalk preparation.
He later supported station operations as a capsule communicator, or capcom, in NASA’s Mission Control Center at Johnson. Kim also contributed to Artemis program development through his work in the astronaut exploration branch, leading the astronaut crew operations branch, and serving as increment lead for Expedition 65. His experiences as a Navy SEAL, physician, and naval aviator provided unique perspectives in mission operations and crew support.
“Jonny approached every assignment with humility, precision, and steadfast commitment to the mission,” said Scott Tingle, chief of the Astronaut Office at NASA Johnson. “His combination of medical training, operational experience, and engineering insight strengthened our team and contributed to advancements in exploration and space station operations.”
Born in Los Angeles, Kim enlisted in the U.S. Navy after graduating high school in 2002. He trained as a hospital corpsman and completed Basic Underwater Demolition/SEAL training before joining SEAL Team Three. Over the course of more than 100 combat operations, he served as a medic, sniper, navigator, and point man, earning the Silver Star, Bronze Star with Combat “V,” and numerous additional commendations.
He earned a bachelor’s degree in mathematics from the University of San Diego and a doctor of medicine from Harvard Medical School. He completed his internship at Massachusetts General Hospital and Brigham and Women’s Hospital in Boston. Kim became a dual-designated naval aviator and flight surgeon, completing flight training at Naval Air Stations Corpus Christi in Texas and Whiting Field in Florida, and aerospace medical training at the Naval Aerospace Medical Institute at Naval Air Station Pensacola.
Kim is returning to active duty to finish out the remainder of his military career within naval aviation training.
“Contributing to space exploration and serving NASA has been the honor of a lifetime,” said Kim. “Throughout my career, I’ve learned that beyond the missions, the training, and the hardware, success always comes down to the people. They are our greatest asset, and leading with love and empathy is how we achieve the impossible. I look forward to carrying my commitment to service, my enduring love for space and technology, and the hard-earned lessons of this past decade into my next chapter to make a meaningful impact on humanity’s future.”

APOD: 2026 August 31 – Launch of the Roman Space Telescope
APOD
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.
Launch of the Roman Space Telescope
Explanation: A new telescope has been launched into space to study the universe. The Nancy Grace Roman Space Telescope (RST) has the same size main mirror as the Hubble Space Telescope (HST) but sees 100 times more sky during each snapshot. This is possible because when compared to HST, RST’s main mirror is more curved, its secondary mirror is closer, and its main camera is larger. The result is that RST can inspect more of the sky more quickly, likely allowing, among other capabilities, the discovery of many more supernovas which tell us more about the expansion rate and composition of our universe, and many more planets orbiting other stars that tell us more about the possibilities for life elsewhere in the universe. RST will orbit the Sun, not the Earth, like the James Webb Space Telescope. The featured video shows Roman being launched yesterday from Kennedy Space Center, Florida, USA aboard a SpaceX Falcon Heavy rocket.

Where is Roman?
Roman is making its three-month journey from Earth to Sun-Earth Lagrange Point 2, or L2. Along the way, Roman is undergoing a process called commissioning, where systems are turned on, adjusted, calibrated, and prepared for science operations. Commissioning is the time for scientists and engineers to make sure that Roman is performing as expected. The schedule is subject to change as the team assesses and adjusts as needed.
Deployments
An hour and 23 minutes after launch, Roman began to emerge from the tight configuration that allowed it to fit in the rocket fairing. The solar panels and sunshade deployed, shading the rest of the observatory and providing power to the systems. Within the upcoming days, the antenna will swing out and the visor-like deployable aperture cover will move into place to permanently reveal and shade the primary mirror.
Roman’s Orbit
This visualization shows the stable, halo orbit that Roman will have around L2. At this location, the gravity of the Sun and Earth, together with an object’s motion around the Sun, let it stay lined up with Earth as they orbit, allowing Roman to have a relatively steady orbit without using much fuel. This location also offers exceptionally stable optical performance and a constant, unobstructed view of a wide swath of the sky; Earth won’t block much of Roman’s view since it will be so distant. And at L2, heat from Earth, the Sun, and the Moon have less effect on infrared telescopes, which “see” heat.
