Aug. 9, 1976: Luna 24 blasts off

9 August 2026 at 14:00

The Soviet Luna program, designed for lunar research and mission planning, ran from 1959 to 1976. On Aug. 9, 1976, Luna 24, the final mission of the program, launched from the Baikonur Cosmodrome in present-day Kazakhstan. The probe landed on the Moon’s surface nine days later, in the Mare Crisium (Sea of Crises), a previouslyContinue reading "Aug. 9, 1976: Luna 24 blasts off"

SpaceX serious about building factories on the moon: 'It’s going to happen,' Elon Musk says

7 August 2026 at 22:00

As usual, SpaceX is dreaming big.

The company plans to build factories on the moon, using robots to do much of the heavy lifting, Elon Musk said on Tuesday (Aug. 4) during SpaceX's first-ever quarterly earnings call.

"We are going to land a lot of tonnage on the moon," he said. "We're going to build the factories on the moon. The robots will be helpful with that."

This is not a newly revealed vision; Musk first laid it out in February, in a blog post that announced SpaceX's purchase of xAI, a company that the billionaire entrepreneur founded in 2023. But Musk doubled down on it this week, showing investors that off-Earth manufacturing is very much front-of-mind for SpaceX.

The factories in question will build SpaceX's Starmind AI satellites, if all goes according to plan. The company aims to operate a million-strong Starmind constellation in Earth orbit in the coming years, and then go farther afield with the craft after that.

Eventually, SpaceX wants to launch locally made Starmind satellites off the lunar surface using electromagnetic mass drivers β€” basically, extremely powerful rail guns.

"Using robots on the moon to scale up manufacturing on the moon β€” which, I know it sounds, like, super sci-fi right now, but it's going to happen β€” will enable us to build the mass accelerator on the moon," Musk said.

"And if you have a mass accelerator on the moon, and you have solar and radiator production on the moon, you can β€” I know this sounds totally nuts β€” but you can you can probably scale to 1,000 times the economy of Earth in terms of intelligence launched to space, but probably, you know, maybe even a million times," he added.

"Solar and radiator production" refers to the manufacture of key Starmind satellite components: solar panels to power them and radiators to dump the large amounts of heat they'll produce into the vacuum of space.

Musk didn't provide details about the robotic lunar labor force. But he's presumably counting on Optimus, a humanoid robot built by another one of his companies, the carmaker Tesla. Musk has previously said that SpaceX will launch some Optimus units to Mars in the near future, to help pave the way for human settlement of the Red Planet.

Those robots will fly on Starship, SpaceX's fully reusable next-gen megarocket, which is currently gearing up for its 14th test flight. Indeed, Starship is key to most of the company's plan's both in Earth orbit and beyond.

"Starship aims to quadruple payload capacity and reduce launch costs by 10 times compared to our Falcon 9 rocket, unlocking significant capabilities across all of our business segments," SpaceX Chief Financial Officer Bret Johnsen said during Tuesday's earnings call.

"We continue to make progress building the infrastructure required to support thousands of Starship launches per year, including accelerating Raptor and launch vehicle production, the buildout of our gigabays, and making significant progress towards activating multiple launch pads at Starbase and in Cape Canaveral at Pad 39A and Pad 37," he added. (Raptor is the engine that powers Starship, and Starbase is SpaceX's South Texas site, which serves as the current hub of Starship manufacturing, testing and launch activities.)

Tuesday's call was a landmark for SpaceX β€” its first as a publicly traded company. Musk founded SpaceX as a private concern in March 2022 and took it public this past June, via the richest IPO in history.

The IPO raised $86 billion and valued SpaceX at $1.77 trillion. Only six American companies had higher market capitalizations at the time β€” NVIDIA, Apple, Alphabet (Google), Microsoft, Amazon and the semiconductor manufacturer Broadcom. (Market caps fluctuate all the time, going up and down with companies' stock prices.)

The main point of Tuesday's call was to discuss SpaceX's first-ever earnings report, which covered the second quarter of this year. The company's revenue over that stretch was $7.8 billion, a 92% increase over the same period in 2025, according to the report. SpaceX lost more money than it made during Q2 2026, but the shortfall was considerably smaller than in Q2 2025 β€” $541 million versus $1.0 billion.

SpaceX rocket's impact crater on the moon spied by Korean lunar orbiter (photos)

6 August 2026 at 16:24

The final resting place of SpaceX's moon-smashing rocket has been found.

The Korea Pathfinder Lunar Orbiter, known as Danuri, has captured imagery of the crater blasted out by the Falcon 9 upper stage that slammed into the moon early on Wednesday morning (Aug. 5).

"Danuri began observations about 30 minutes before the collision and, through orbit control, passed over the impact site multiple times, conducting a total of 8 imaging sessions," officials with the Korea Aerospace Research Institute (KARI) said via X this morning (Aug. 6). "Through this observation, changes in the terrain around the impact site and traces of ejecta spread were confirmed."

"Danuri secured both pre-collision and immediate post-collision footage, enabling analysis of changes caused solely by the collision and providing important research data," they added in the X post, which shared several before-and-after images of the impact site.

The Falcon 9 in question launched on Jan. 15, 2025, sending two private robotic moon landers β€” Firefly Aerospace's Blue Ghost and ispace's Resilience β€” to a high, moon-crossing Earth orbit. The duo then made their own way to the moon; Blue Ghost landed successfully on March 2 of that year, but Resilience crashed during its touchdown attempt.

The Falcon 9's first stage came back to Earth shortly after liftoff for recovery and reuse, as such boosters commonly do. Falcon 9 upper stages, by contrast, are expendable. SpaceX usually disposes of them in Earth's atmosphere, but the upper stage on the Blue Ghost-Resilience mission used almost all of its fuel getting its payloads to their distant destination. So the 8,800-pound (4,000 kilograms) rocket body remained up there, orbiting Earth β€” until solar activity and gravitational forces pushed it on a collision course for the moon.

That collision occurred at 2:34 a.m. EDT (0634 GMT) on Wednesday, according to KARI officials β€” right in line with predictions. Scientists calculated some other parameters ahead of time as well. For example, the rocket body probably hit the moon at about 5,400 mph (8,690 kph), gouging out a crater up to 89 feet (27 meters) wide.

The new observations by Danuri, as well as future work by other lunar probes, will help verify such predictions.

"The observation data secured by Danuri will be linked with follow-up observations from NASA's Lunar Reconnaissance Orbiter (LRO) and utilized in international collaborative research," KARI officials said in the X post.

It may be that some ground-based telescopes caught the impact as well. Astronomers at the Instituto de AstrofΓ­sica de AndalucΓ­a in Spain believe they captured a video of ejected material blasting off of the lunar surface around the predicted time of impact:

The Falcon 9 upper stage wasn't the first rocket body to slam into the moon. The third stage of a Chinese Long March 3C crashed into the lunar surface on March 4, 2022, for example. And the third stage of NASA's Saturn V rocket gouged out craters during multiple Apollo moon missions.

Danuri is South Korea's first lunar probe. The spacecraft launched on Aug. 4, 2022 atop a Falcon 9 and began circling the moon four months later. It carries six payloads, five of them provided by Korean universities and research organizations. The sixth is a NASA instrument called ShadowCam, which hunts for signs of water ice in permanently shadowed regions at the lunar poles.

SpaceX’s Falcon 9 wasn't the first rocket to crash into the moon. Here's a rundown

A spent rocket body hitting the moon made headlines this week, but the reality is that the unplanned collision by a SpaceX upper stage was just the latest in a long history of human-made objects meeting their end by impacting the lunar surface.

Astronomers around the world kept their telescopes trained on the moon early Wednesday morning (Aug. 5), when the rocket stage from a January 2025 U.S. commercial lunar landing mission was calculated to strike the celestial body. Though the fate of the SpaceX Falcon 9 part was unintentional β€” solar activity and gravitational forces caused the stage to slam into the moon β€” the impact offered a rare opportunity to try to observe the flash from the impact and the plume of lunar material it sent flying.

By noon (EDT) on Wednesday, there were no confirmed reports of the impact being caught on film, but a telescope in Chile spotted the debris plume, according to the Associated Press.

"This rare occurrence has decades of history, going back to the Apollo era," wrote Jared Isaacman, NASA's administrator, in a post to his social media accounts. "The reality is that meteoroids strike the lunar surface hourly, with impacts comparable to this upper stage occurring roughly every six days."

Inventorying the impacts

The moon is peppered with the scattered metal remains of missions that missed their mark, came down too quickly or were purposefully sent careening into the regolith to learn more about the makeup of Earth's natural satellite.

In fact, the very first mission to successfully fly by the moon was intended to be an impactor. The former Soviet Union's Luna 1 probe was designed to hit the moon but instead zoomed past its target and entered orbit around the sun on Jan. 2, 1959.

Luna 2, launched nine months later, became humanity's first object to reach the lunar surface, purposefully slamming into Sinus Lunicus ("Bay of Lunik"), along the southeastern edge of Mare Imbrium, on Sept. 14, 1959.

The U.S. followed suit, though not as NASA intended, with the Ranger 4 probe impacting the far side of the moon on April 26, 1962. The mission had included an impactor, but both it and its lander failed to operate due to a failure to deploy the spacecraft's solar arrays.

Once humans began arriving on the moon with NASA's Apollo program, scientists found another reason to direct spent rocket and spacecraft stages into a collision course with the surface. Beginning with Apollo 11 in 1969 and concluding with Apollo 16 in 1972, seismometers were placed on the moon to measure natural "moonquakes" and the effects on the moon when the missions' Saturn SIV-B stages and Apollo lunar module descent stages made hard landings.

The data collected helped geologists learn more about the interior makeup of the moon, including that a rocky mantle exists under the outer crust.

After Apollo, planned impacts (and missions) slowed down, if not outright stopped, but the SpaceX collision on Wednesday was not the first in more than 50 years. Between 1993 and today, 11 probes β€” four from China, three from Japan, two from the U.S. and one each from India and the European Space Agency (ESA) β€” were intentionally deorbited at the end of the end of their missions around the moon.

Some of these impacts were performed to discard the craft, but others β€” like Lunar Prospector, LCROSS and Chandrayaan-1 β€” helped confirm the presence of water by examining the resulting plume.

Unintentional collisions are fewer in number, as are rocket stages, but are not unprecedented. A rocket body that hit the moon's far side in March 2022, leaving behind a small double crater, was later identified as a Long March 3C rocket that launched China's Chang'e 5-T1 mission around the moon in 2014.

Litter versus liability

Without a large human population on the moon, the risk that these planned and unplanned impacts present at current is minimal. But the concern rises as NASA and other world space agencies, as well as commercial interests, begin to increase the pace on establishing their now-planned sustainable facilities for astronauts to live and work on the lunar surface.

"The future lunar base will incorporate reusable spacecraft that not only deliver astronauts and payloads, but also become part of the infrastructure itself," Isaacman said in his post, referring to how reuse can be a way to reduce the number of vehicles needed to be discarded of on the moon.

The Artemis Accords, an internationally agreed-upon set of standards led by NASA and currently signed onto by 70 countries, also includes a provision for its members that spacecraft and their associated rocket components must be disposed of safely.

A SpaceX rocket just crashed into the moon. Now, the race is on to get a look at the impact site

5 August 2026 at 18:43

Early this morning, a SpaceX rocket slammed into the moon at seven times the speed of sound. Now, lunar orbiters are trying to get a look at the aftermath.

This morning (Aug. 5) at about 2:35 a.m. EDT (0635 GMT), the upper stage of a SpaceX Falcon 9 rocket crashed into the moon. To dissect what exactly happened, scientists are looking for imagery of the crash site, with the help of a couple of moon probes.

"NASA’s Lunar Reconnaissance Orbiter and NASA’s ShadowCam instrument on the Korea Pathfinder Lunar Orbiter will look for opportunities to capture before‑and‑after imagery of the impact site," NASA spokesperson Rob Garner, of NASA's Goddard Space Flight Center in Maryland, told Space.com. "Image availability depends on several factors, including the impact location, lighting conditions, and when each spacecraft’s orbit next carries it over the area, which may take a few days to receive any imagery."

While you've likely seen the first stages of Falcon 9 rockets gracefully land back on Earth for reuse, the rocket's 9,000-pound (4,000 kilograms) upper stage is disposable. Typically, it's sent to burn up in our atmosphere after its missions are over.

However, that wasn't possible with this rocket, which launched two private lunar landers β€” Firefly Aerospace's Blue Ghost and Tokyo-based ispace's Resilience β€” to a high, moon-crossing Earth orbit in January 2025. The Falcon 9 upper stage used most of its fuel getting to this distant location and couldn't make it back to deorbit in Earth's atmosphere.

So the company performed a different maneuver to take care of this upper stage, Julianna Scheiman, director of NASA science and Dragon programs at SpaceX, said during a press conference on Aug. 3.

"For high-energy missions, we need to perform a different maneuver to ensure the second stage itself is safe per the appropriate rules and regulations, and so we did that here," she said.

But the rocket body was still subject to natural forces, which acted on it over time.

"What has happened is, essentially, a mixture of solar activity and gravity forces have put it on a path towards the moon," Scheiman said.

The Falcon 9 upper stage ended up slamming into the moon this morning at about 5,400 mph (8,690 kph). It likely blasted out a crater up to 89 feet (27 meters) wide, according to scientists' calculations.

This was certainly not the original intended outcome for this rocket. But it presents an opportunity for researchers, who plan to take advantage of it to learn more about the moon.

"NASA’s Meteoroid Environments Office will attempt to image the impact around the predicted time using ground‑based telescopes at the agency's Marshall Space Flight Center in Huntsville [Alabama]," Garner added. "Because the impact flash and plume are expected to be faint, the chance of seeing anything from Earth remains low, and local weather can affect observations as well. Any data collected will help scientists better understand impacts from artificial objects and the potential effects on future lunar exploration."

Today's impact took place on the sunlit side of the moon, the brightness of which made observations difficult for skywatchers hoping to watch the crash from afar with telescopes. But the two lunar orbiters might be able to see not just the crash and impact crater but also the plume of dust kicked up by the rocket's death dive.

So far, observations from Earth have revealed some information. Scientists at the Lowell Observatory in Flagstaff, Arizona reported detections of a lunar plume from the impact.

"We can safely say that we measured a response from the rocket stage impact as a sodium and lithium gas plume a few 10’s of kilometers in size lasting between 5 and 10 minutes after impact," Carl Schmidt told Inside Outer Space's Leonard David.

Such images of the event would provide "an opportunity to test pipelines for measuring flash properties to locate impact events seismically, and to better understand the multi-modal hazards posed to future lunar infrastructure and astronauts from space debris impacting the moon," researchers led by Benjamin Fernando of Los Alamos National Laboratory in New Mexico wrote in a recent paper discussing the then-upcoming event.

So hold tight, as researchers are now eagerly collecting and analyzing the images captured by these orbiters, and we might get images of the rocket crash, the lunar plumes and remaining aftermath soon.

An Out-of-Control SpaceX Rocket May Have Struck the Moon with the Force of Three Tons of TNTβ€”Here’s What We Know

5 August 2026 at 15:08

A portion of an out-of-control SpaceX rocket is believed to have collided with the Moon on Wednesday, producing a new impact crater.

The roughly 8,800-pound rocket stage is suspected of striking the lunar surface at around 2:35 a.m. EDT, with a force comparable to three tons of TNT, according to experts. The new impact crater and resulting cloud of lunar dust could help scientists glean new insights into how impacts have shaped the Moon’s surface over time.

As of 9 a.m. EDT Wednesday, observations have yet to confirm whether the collision occurred, although it was suggested that a faint flash of light might be visible in the suspected region, located near Einstein Crater, using Earth-based telescopes. No obvious signs of the crash were reported by amateur astronomers.

Additional imagery may have been obtained from any of the several ground-based observatories in the United States that were monitoring for signs of an impact, although analysis of any imagery collected this morning could take several days.

Imagery obtained by NASA’s Lunar Reconnaissance Orbiter is expected to capture images of the newly formed crater in the days ahead.

How Did a SpaceX Rocket Stage Collide with the Moon?

The rocket stage originated from a Falcon 9 launch in 2025, which carried a pair of lunar landers toward the Moon.

One was Blue Ghost, a lunar lander developed by Texas-based Firefly Aerospace as part of NASA’s Commercial Lunar Payload Services (CLPS) initiative under the Artemis program. Blue Ghost shared its ride with Japanese company Ispace’s Resilience lunar lander, with each mission aiming to promote a future sustainable lunar economy and provide transportation services for government and private-sector customers.

While most SpaceX rocket upper stages burn up in Earth’s atmosphere during reentry, or are deposited in the ocean following their launches, the stage from the Falcon 9 launch in question remained in space after its fuel was expended, since the lunar mission necessitated additional velocity to escape Earth’s orbit.

Despite these conditions, SpaceX had not intended for one of its rocket stages to collide with the Moon. It was revealed earlier this year that the combined influence of gravitational forces and solar activity was anticipated to alter the spacecraft’s trajectory enough to place it on a collision course with Earth’s natural satellite.

Having exhausted its propellant during its primary mission, the rocket stage had no way to perform course adjustments to prevent the collision.

β€œIt’s very infrequent to have things like the Falcon 9 second stage crash into the moon,” NASA Administrator Jared Isaacman said during a live segment on Fox News. β€œIt’s not a big deal right now. The moon has clearly seen better days,” Isaacman added.

No Risk to Earth, and Insights May Be Beneficial

Fortunately, NASA officials have confirmed there is no danger posed to Earth from this morning’s collision. Additionally, the impact could offer some benefits by providing scientists with a unique opportunity to observe a new crater’s formation, which may shed light on how such events have shaped the lunar surface over time.

Specifically, the fact that this impact was predicted well enough in advance to potentially allow for imagery to be obtained during or shortly after the new crater was formed, could provide rare insights into the dynamics of how craters on the Moon develop.

Additional information from the impact plume produced as lunar regolith is ejected from the impact site could offer valuable data for space agencies like NASA, which are currently preparing for a sustained human presence on the Moon.

Space Debris is Still a Concern

Although the impact this morning was largely benign, this incident does underscore the growing challenge of managing space debris.

Abandoned rocket hardware and other debris from space missions can pose long-term risks. While remaining in orbit, such materials can damage operational satellites or other spacecraft. Once they make their way back into Earth’s atmosphere, these leftovers from past space missions can sometimes survive reentry, even though they are designed to disintegrate when subjected to such conditions.

In recent years, a growing number of components associated with SpaceX rockets have survived reentry and collided with Earth. In May 2024, The Debrief was the first to report that an object discovered on a stretch of property in the Western North Carolina mountains was likely space debris from a SpaceX launch, which NASA officials later confirmed.

More recently, a series of unusual metallic spheres were discovered by residents of a beachside community in Australia, which were also confirmed to have been materials associated with a SpaceX launch.

Fortunately, no injuries or damage to property have been reported following these events.

As lunar orbiters begin returning images of the impact site, scientists hope the unexpected crash will provide a valuable new dataset for understanding one of the Solar System’s most heavily cratered worlds.

A SpaceX rocket will hit the moon at 5,000 mph tonight. Experts explain what you could see, and when.

4 August 2026 at 17:36

An abandoned part of a SpaceX Falcon 9 rocket is projected to crash into the moon at 2:35 a.m. EDT on Aug. 5 β€” and two new studies suggest the event may be visible in telescopes from parts of North and South America, providing both amateur and professional astronomers with a rare, real-time viewing opportunity. Both studies are available as preprints on the arXiv server.

The impending Aug. 5 impactor is the truck-sized spent upper stage of a Falcon 9 rocket. In 2005, the rocket boosted two privately owned landers into orbit around the moon, before leaving its upper stage in an elliptical orbit around Earth, according to OrbitalRadar.com.

A report earlier this year estimated that the collision would occur near the moon's Einstein crater, with the rocket grinding into the lunar surface at a speed of 5,436 mph (8,748 km/h). Although that sounds fast, it's about six times slower than a natural impactor, like an asteroid, would hit.

What can you see with a telescope?

The initial impact flash of the collision β€” which will last less than a second and be hidden on the sunlit side of the moon β€” will likely be invisible to casual skywatchers, according to one of the new studies. The brightest estimates for the impact put it at 20 times dimmer than Saturn. The resulting crater likely won't be visible from Earth, as the study estimates that the hole is relatively small and shallow β€ͺ—‬ about 90 feet (27 meters) wide and up to 16 feet (5 m) deep.

More promising for Earthbound skywatchers is the plume of regolith (and potentially water vapor) the impact will loft. The plume will likely reach several miles in height, with computer-based simulations from the second study showing it may tower up to 31 miles (50 km) high. This will make it visible over the moon's limb as a cloud, with the debris spreading up to 112 miles (180 km) from the impact site.

The plume will hang above the lunar surface much longer than the flash β€ͺ—‬ for up to 400 seconds, or close to seven minutes; during this time, it will scatter sunlight toward Earth. Even then, the plume will be too faint to be observed with the naked eye, William Jo, a graduate research assistant at the University of Texas at Austin and co-author of the second study, told Live Science in an email. Viewers will need a good backyard telescope to see it.

"Where the science is"

Although the event will be dim and occur on the sunlit portion of the moon, skywatchers are gearing up to watch it. Benjamin Fernando, a postdoctoral researcher at Los Alamos National Laboratory and co-author of the first study, told Live Science in an email that there "will be an observing campaign involving professional and amateur astronomers from around the world."

In particular, he said, folks in South America and continental North America β€” where it will be night, with the moon high above the horizon β€” will have the best chance of seeing it, although you will need at least a 4-inch (10 centimeters) telescope.

However, Jo was less optimistic. "I don't think it would be an easy task for an amateur astronomer," he said, but if they know exactly where to point their telescope and tackle atmospheric refraction, they might see the plume. Nonetheless, he urged well-equipped observers to try observing the plume, as that is "where the science is."

This science, Jo said, would help researchers understand how everything delivered to or disposed of on the moon will ultimately affect the lunar surface. "This would be useful for studying disposal methods for upper stages, maybe how far ejecta will travel, and whether or not the ejecta will hit sensitive instruments, or in the far future lunar bases," he added.

Previous collisions of human-made objects on the moon have likewise led to some major scientific insights. For example, the 2009 crash of a Centaur rocket's upper stage was analyzed by NASA's Lunar Crater Observation and Sensing Satellite mission, which revealed subsurface ice near the lunar south pole. As a result, the lunar south pole is now considered the most coveted location for moon missions that aim to establish a permanent human presence on Earth's satellite.

A SpaceX rocket will crash into the moon next week, and scientists aren't sure what to expect

30 July 2026 at 11:00

On Aug. 5, Earth's moon is due for a human-made, high-speed impact from an identified flying object: a spent SpaceX Falcon 9 upper stage. The event will lead to a literal "dust up" on the lunar landscape.

That Falcon 9 upper stage is a leftover from the launch that sent Firefly's Blue Ghost-1 lander to the moon on Jan. 15, 2025. Onboard the same flight was the Hakuto-R Mission 2, called Resilience, a robotic lunar lander developed by the Japanese company ispace.

And according to a new study by an international team published on the open-source arXiv server, the resulting impact plume may briefly be bright enough to see against the dark sky near the moon's edge. That means it might be visible to moongazers with sufficiently sensitive telescopes.

This head-on collision of the errant stage is expected to occur near the Einstein and Bell craters near the western lunar limb. It may well be visible to ground and space-based assets. Indeed, putting aside all the unknowns and modeling uncertainties, some specialists suggest if you've got the time and observational prowess, it might be worth a look.

Visible ejecta spike

Using special physics simulations to model the impact, William Jo, a graduate research assistant at the University of Texas, Austin and colleagues predict the debris plume from the impact will have the central ejecta spike reaching roughly 47 miles to over 60 miles (75 kilometers to 100 kilometers) altitude.

"Our calculations suggest the plume should be several orders of magnitude brighter than the dark-sky background for the first few minutes after impact," Jo told Space.com. "So the plume should be visible, though I'd stress this is a single nominal case. The real one will look different, and the numbers are on the optimistic side. But the point worth making is that the flash isn't really the story here."

Jo emphasized that there's great slam-dunk science to be had. "Watching this one gives us a rare chance to open up ejecta-plume science and calibrate those models against a real event, which matters for every future thing we deliver to the moon," Jo said.

Implications for future moon missions

According to new research led by Benjamin Fernando of the Los Alamos National Laboratory in New Mexico, the impact flash and resultant ejecta plume are "potentially observable" from ground- and space-based observational facilities.

"This event provides an opportunity to attempt the recording of an artificial impact in real-time; although many of the properties of the event (such as visual magnitude) are imprecisely predicted at present," Fernando and colleagues report.

Moreover, this rocket stage meets moon occasion yields an opportunity to test a pipeline for localizing impacts on the lunar surface for future seismic experiments, investigating the dust and plume dynamics from impact events on the moon, and considering hazards from artificial space debris impacts that future astronauts on the lunar surface might have to avoid, Fernando and team members point out.

"The maximum ballistic range of resolved particles is found to be slightly under 1,000 km, which is far enough to be significant from the perspective of presenting a hazard to future astronauts or infrastructure across much of the lunar surface," Fernando et al wrote in the study.

Before and after

Brent Garry is a project scientist for NASA's Lunar Reconnaissance Orbiter (LRO) at Goddard Space Flight Center in Greenbelt, Maryland. LRO will be passing over the projected rocket stage crash site about seven days prior to the impact and about seven days after the impact, Garry explains.

"After the impact we might have a little bit more knowledge of where it is. We can do some additional targeting about a week after the impact and get some targeting over where the site is," said Garry, as noted in earlier Space.com reporting.

Meanwhile, Jo at the University of Texas, Austin underscores the fact that a spent rocket stage is a hollow, spacecraft-like body, and there are very few impact models for human-made objects like it. They seem to produce very different plumes than natural impactors, like asteroids or comets do. But Jo stresses that the real scientific contributions will come by studying the moments after the impact.

"My concern is that most observers will stop at the sub-second flash and never track down the ejecta, which is the part that should actually be visible, and where the science is."

Catch an orange 'Buck Moon' rise tonight before a month of solar and lunar eclipses

29 July 2026 at 11:05

July’s full Buck Moon, the second full moon of summer in the Northern Hemisphere, will turn full on Wednesday (July 29). It will be the final full moon before a flurry of solar and lunar activity β€” notably, a total solar eclipse caused by the new moon on August 12, and a partial lunar eclipse during the following full moon on August 28.

Named for the new antlers that emerge from male deer during summer, July’s full moon is also known as the Thunder Moon and Hay Moon, according to Time and Date. The Anishinaabeg people call it Miin Giizis, or Berry Moon, according to the Center for Native American Studies.

The Buck Moon will be at its fullest at 10:37 a.m. EDT on Wednesday β€” however, it will also look bright and full on Tuesday and Thursday night. From North America, the best time to see it will be at moonrise in the southeast during dusk on Wednesday evening. The exact time of moonrise will depend on your location. A full moon looks most dramatic as it first appears above the eastern horizon shortly after sunset, with Rayleigh scattering making it loom orange β€” the same light-scattering phenomenon that makes the sky blue and sunsets red.

July's full moon is one of the lowest full moons of the year as seen from the Northern Hemisphere because it occurs relatively soon after the June solstice. A full moon always sits opposite the sun, so the path of July's full moon mirrors the sun's path in February.

You can easily enjoy the full moon with the naked eye, but a good backyard telescope or pair of stargazing binoculars can help you zoom in on famous structures, such as craters and Apollo landing sites. And if you want to take stunning photos of the moon, here’s everything you need to know.

Two weeks after theBuck Moon, the new moon will slide directly between Earth and the sun, causing a total solar eclipse. Observers along a narrow path of totality in eastern Greenland, western Iceland and northern Spain will see the moon block the sun for a few minutes, revealing the solar corona.

A deep partial solar eclipse will be visible across Europe, with a small partial solar eclipse observed over Canada and the northeastern U.S.. The largest eclipse in Canada will be 93% in northeastern Nunavut, while northeastern Maine in the U.S. will see 29% of the sun covered by the moon. Solar eclipse glasses must be worn at all times to safely view the partial phases.

The next full moon, the Sturgeon Moon, will rise on August 27 and be partially eclipsed by Earth overnight. More than 96% of the moon will pass into Earth's shadow as seen from Europe, Africa, North America and South America.

Moon landings could destroy evidence of life's origins

14 July 2026 at 11:00

Landing spacecraft on the moon could contaminate ancient clues about how life may have originated on Earth, a new study finds.

As NASA continues on with its plan of sending astronauts back to the moon with the Artemis program, researchers are exploring what possible unintended consequences may arise from humans visiting the lunar surface. For instance, Artemis IV will land astronauts near the moon's south pole and the agency has future plans for building a longer-term moon base on the lunar surface, which would require many more trips. And indeed, a new study has found the exhaust from spacecraft involved with these landings could expel enough methane to contaminate the moon's surface β€” possibly destroying molecules that could help to explain how life may have originated on Earth.

"We are trying to protect science and our investment in space," senior study author Silvio Sinibaldi, the planetary protection officer at the European Space Agency, said in a statement. "Our activity can actually hinder scientific exploration."

While experts have had concerns for some time about how rocket launches on Earth pollute our planet and atmosphere, scientists have only really considered this issue with our own planet. This is especially because we haven't been to the moon's surface in over 50 years; concerns of accidental effects of a lunar landing simply haven't been top-of-mind. That's what makes this new study so important. It points to a potential issue that could mean that future moon landings might actually be detrimental to science.

Life's clues on the moon?

So why do we think the signs of life could be hiding on the moon? It's actually hiding in ice. Dark craters near the moon's poles, which exist in perpetual shadow, hold ancient ice. This ice is thought to contain material from asteroids and comets that smashed into the moon billions of years ago. Trapped in lunar ice to this day, these bits of ancient collisions could include what the researchers describe as "prebiotic organic molecules," or molecules that could have preceded life on Earth.

It's thought that these molecules from asteroid and comet visitors could have sparked life on Earth, and by studying those possibly trapped on the moon, researchers could be looking at the molecules that ended up combining and creating life as we know it.

The molecular history of life on Earth is pretty much nonexistent on our own planet, as it was largely destroyed by the billions of years of changes we've experienced. But the moon has remained mostly unchanged, so these wells of ice are a uniquely-preserved sampling of pre-life molecules.

"We know we have organic molecules in the solar system β€” in asteroids, for example," Sinibaldi said. "But how they came to perform specific functions like they do in biological matter is a gap we need to fill."

This ice exists in a somewhat fragile ecosystem, so left alone in darkness, this ice isn't going anywhere anytime soon. But with Artemis, NASA is planning on sending crewed landers to the moon's south pole. That might pose a problem. With computer models in this new study, researchers have shown that the methane exhaust from these landers could very quickly and permanently contaminate this ancient ice, destroying the molecular evidence sealed within.

Inside the simulations

In those computer models, the researchers simulated how methane, the main organic component expelled by planned lunar landers, would spread across the moon's surface after a landing at the south pole. While the simulations included the effects of solar wind and radiation, the moon's lack of an atmosphere caused the methane to spread incredibly quickly, reaching the moon's north pole in under two lunar days.

Within one lunar week (which is roughly seven months on Earth), over half the methane was trapped at the moon's cold polar areas, with a whopping 42% of the substance trapped at the south pole compared to 12% at the north pole. This methane could collect in the same cold pockets where ice and ancient molecules have been collected for billions of years, possibly contaminating this finite, scientific evidence.

"Their trajectories are basically ballistic," lead author Francisca Paiva, a physicist at Instituto Superior TΓ©cnico in Portugal, said in the statement. "They just hop around from one point to another."

In better news, there may be a way to circumvent some of this methane disturbance. For instance, the study suggests it's possible that by choosing colder landing sites, scientists can avoid having the methane travel as quickly or as far. Additional simulations are needed to better understand how exhaust compounds travel on the moon, however, as well as the risks that this poses for scientific investigations and if there are other materials lunar trips will involve that could contaminate the environment. Above all, the new study's team emphasizes that as we push toward future lunar exploration, it is key to balance our dreams of settling the moon with preserving its priceless history.

"We have laws regulating contamination of Earth environments like Antarctica and national parks," Paiva said. "I think the moon is an environment as valuable as those."

This work was described in a study published last year in the journal the American Geophysical Union.

'Let's not fool the public': Why moon art should be more realistic in the Artemis age

22 June 2026 at 16:00

GOLDEN, Colorado β€” The moon is in need of good and accurate artists!

As NASA's Artemis program hits its stride, and in a few years "reboots" our moon with a human presence, there's an urgent need to guard against artistic misrepresentations of the lunar landscape, experts say.

We've all seen those alluring lunar renderings of vehicles and astronauts bounding about while setting up equipment and putting in place a moon base.

Reality versus depictions

"We are telling the public the moon is easy β€” it is not!"

That's the matter-of-fact warning from Daniel Britt, the Pegasus Professor of Astronomy and Planetary Sciences in the Department of Physics at the University of Central Florida. He's also the director of the Center for Lunar and Asteroid Surface Science.

Britt spoke about and showcased artists' misconceptions during a "reality versus depictions of the lunar surface" talk here at a Space Resources Roundtable, held from June 2 to June 5 on the campus of the Colorado School of Mines.

"I wish I could say that engineers and managers know better, but they don't. We are training a generation of engineers to not worry about terrain. If the artists are getting it wrong, it is our fault. Let's stop fooling ourselves," Britt said.

Well versed in what the lunar surface truly offers, Britt scolded a number of arty accounts of lunar territory promulgated by both NASA and commercial space ventures. He spotlighted what's wrong with those pictures β€” for starters, small craters and ever-present lunar dust, along with dirty astronauts, dirty equipment and dirty habitats.

Facts of life

A flat, dustless moon is not the one we are sending Artemis astronauts to, said Britt. Crews will experience coarse terrain, pervasive dust, and a surface unlike anything here on Earth. These are the facts of life on the moon, he said.

The Apollo moon-landing missions learned this first hand. But those astronauts explored equatorial areas. The Artemis program is targeting the lunar south polar region, which will be tough to deal with thanks to the low angle of the sun.

"When you look into the sun, it will be blasting into your face. But at least you'll see the shadow of that crater you are about to trip into," said Britt. "But looking down-sun, you won't see diddly squat."

"There's need to stop deluding ourselves," Britt told Space.com, advocating the creation of a 1-to-10 scoring system for lunar art, with prizes for the worst and best visualizations

"What I want to do is land on the moon way safer and easier," he added, "so you need to ask yourself what's missing from these depictions. We are training the public to think this is easy."

False impression

To support his concern, Britt spotlighted both Apollo moonwalker-taken imagery and the scenery as projected by artists, be it using paint brush or artificial intelligence-guided computer work.

"The sun angle washes out the rough terrain. Almost all the pictures taken from the surface give the very false impression of a flat, gentle terrain," Britt said. "The reality is that the lunar surface is heavily cratered, rough, very dusty and covered in regolith."

Most Apollo surface images were taken "down-sun" because looking "up-sun" was hard. "This leaves a very false impression of a flat moon with gentle terrain," Britt said.

Tilt problems

Apollo was pretty lucky, Britt said, observing that several of the six human moon landings experienced tilt problems. For instance, Apollo 14 experienced a 7-degree tilt on landing, and Apollo 15 had an 11-degree tilt on touchdown.

Apollo 11 had to dodge a boulder field. Apollo 12 and Apollo 16 landed on the edge of big craters. "Even small craters can be meters deep," said Britt, recalling problems encountered by astronauts on their descent to the moon.

"The dust went as far as I could see in any direction and completely obliterated craters and anything else … I couldn't tell what was underneath me," astronaut Pete Conrad said during an Apollo 12 debriefing. "I knew I was in a generally good area, and I was just going to have to bite the bullet and land, because I couldn't tell whether there was a crater down there or not."

Similarly, Apollo 16 commander John Young said: "I couldn't judge slope out the window worth a hoot, and that's the truth. Even down low. The ground looks flat, but I'm sure it would look flat if it had been a 6-8 degree slope, too. I don't see any way around that."

Getting it wrong

A flat, crater-free, dustless moon is a staple of imagery issued by NASA, the European Space Agency, other space agencies, and even private space firms, said Britt.

"Yes, these are artists' impressions," Britt said, "but somebody is telling the artists what to draw. I love the idea of landing and operating on a moon without dust, small craters, and rough terrain. However, we see the misconception of a flat, gentle moon everywhere."

"Commercial providers are just as bad. No dust, almost no small craters, no tipping problems. Yes, these are artists' impressions, and they are getting it wrong," said Britt. "NASA knows better. All these people should know better, but don't. Let's not fool the public. We owe them better data."

This Curious Moon Rock Preserves Evidence of Ancient Impacts Across Three Worlds

10 June 2026 at 12:56


The ancient history of our planet’s impact events is coming into focus, thanks to researchers who have triangulated similarly aged impacts on Earth, the Moon, and the asteroid 4 Vesta in a new study.

The lunar meteorite NWA 12593 correlates not only with impact events observed across three locations in our solar system but also contains evidence of three separate impact events that occurred at different times.

The findings, revealed in a recent paper published in Geology, show that scientists are using this new impact data to fill in the volatile early-Earth period when life began.

Early Earth Impacts

The Archean period, roughly 4 to 2.5 billion years ago, was a consequential time from which our earliest fossil records date, corresponding to around 3.5 billion years ago. Researchers believe that life likely first arose at this time, yet it may have faced adversity from bombardment by space rocks between 3.2 and 3.5 billion years ago, although scientists disagree on how intense this impact activity was.

Our planet’s geological activity eventually destroys evidence of the ancient past through erosion, subduction, and burial, continually reshaping the surface. Yet those early years are essential to understanding the origins of water, atmospheres, and life on Earth.Β 

β€œOn Earth, the first fossil evidence of life shows up around 3.5 billion years ago, meaning that life is emerging and evolving before then. The question that we often have, even going back further, is what was the impact record when life was emerging?” said lead author Carolyn Crow, a planetary scientist at the University of Colorado Boulder.

β€œIt is important for understanding how life is taking hold, how life is emerging,” Crow added. β€œThe cadence of these catastrophic events is an important part of the equation.”

A Neighbor Remembers

While Earth’s surface is constantly renewed by geological processes, our nearest significant neighbor, the Moon, is much more stable, retaining its geological record for longer periods. Because of this, lunar meteorites provide a resource for scientists to understand the impact of Earth and the inner solar system by matching them to known impacts on our planet and in the asteroid belt.

For the recent study, the team focused on a lunar meteorite discovered in northwest Africa, designated NWA 12593, and identified three separate impact events in a single sample.Β 

Radiometric dating traced the oldest to 3.5 million years ago, intriguingly close to the time of the earliest known fossils. Extraordinary in power, this impact produced the mineral zirconia by melting the lunar surface into a lava-like flow. Without the precise laboratory conditions required to produce stable cubic zirconia, only traces of mineral remained in the sample.

According to the team, the first impact aligns with previously known impact events on Earth, and the fourth-largest object in the asteroid belt, 4 Vesta. It’s extremely rare to find such corresponding evidence between three bodies, providing important data on this time of frequent collisions.

β€œIt’s not very common, which is why we’re very excited about it,” says Crow. β€œIt’s pretty rare to have all three records line up like this.”

Later Impacts

Evidence of later impacts included breccia composed of large, angular, broken mineral fragments cemented together. The team believes the breccia resulted from a second impact that struck the melt sheet formed by the first.

β€œBreccias are similar to what you would see if you went and chipped out a chunk of concrete. You would see all these little rocks, and then it’s fused together by the cement,” says Crow. β€œBut the meteorite is fused together by the impact process. You get all these chunks of different kinds of rocks that the impact hit into. These all get mixed up, and then it gets fused together like your concrete sidewalk.”

As for the third impact, the evidence for this is the meteorite’s mere presence on Earth; an event that occurred some time after the first would have ejected the lunar breccia, the researchers say, allowing it to eventually land on our planet.

In total, the sample reveals an intriguing impact history, preserving a record of bombardment that provides solid evidence for a flurry of activity in the inner solar system during a violent chapter in the early history of our Solar System.

The paper, β€œThree-Body Evidence of Ca. 3.7 Ga to 3.2 Ga Bombardment Across the Inner Solar System,” appeared in Geology on May 12, 2026.

What Happened to Earth’s Rings?

18 August 2025 at 04:15
The existence of evidence for Earth’s past equatorial ring, shown by impact craters, raises questions about its loss. Modeling its effects on Earth's rotation presents challenges. However, current findings indicate minor impacts on day length, with significant stability in the Earth-Moon system over 10,000 years.
