La sonda Danuri ha fotografato la macchia scura lasciata dallo schianto di uno stadio superiore di un razzo Falcon 9 di SpaceX sulla superficie lunare. Il componente, lungo 14 metri, è stato spinto fuori rotta dall'interazione tra gravità e vento solare, finendo per impattare vicino al cratere Einstein a oltre 8.000 km/h. L'evento, confermato anche dai rilevamenti dello spettro gassoso dal Very Large Telescope in Cile, ha scavato un nuovo cratere di 18 metri di diametro, riaccendendo l'attenzione dei ricercatori sulla gestione dei detriti spaziali nelle orbite cislunari.
Un étage supérieur de Falcon 9 s'est retrouvé sur une trajectoire de collision avec la Lune. Si nous n’avons aucune image du moment de l’impact, un satellite coréen a pu prendre les premières images du cratère.
As imagens captadas pela sonda Danuri permitiram aos investigadores da Administração Aeroespacial da Coreia do Sul confirmar que a colisão do estágio superior do foguetão da SpaceX causou alterações na superfície lunar. Além da Danuri, a Lunar Reconnaissance Orbiter da NASA também vai fotografar o local do impacto.
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.
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.
“It’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. “It’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 spacecraft fitted with two flexible robotic arms is on the way to geosynchronous orbit after launching earlier this week on a SpaceX Falcon 9 rocket, kicking off a planned decade-long mission to open new frontiers in satellite servicing.
The Mission Robotic Vehicle, owned and built by Northrop Grumman, rocketed into orbit from Cape Canaveral Space Force Station in Florida on Tuesday. Three small propulsion pods, each functioning as standalone spacecraft, accompanied the MRV aboard the Falcon 9 rocket.
The Falcon 9 deployed all four payloads within about an hour of liftoff. It will take about a year for the satellites to maneuver from their initial elliptical drop-off orbit into a circular orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator. At this altitude, the MRV and the three Mission Extension Pods (MEPs) will travel in lockstep with Earth's rotation, operating in the same kind of orbit as numerous civilian and military communications satellites, missile warning platforms, and a growing number of spy satellites.

Welcome to Edition 9.04 of the Rocket Report! We've had to wait an extra week for SpaceX to get its 13th Starship test flight off the ground. A last-second abort on July 16 led engineers to roll the booster back to its hangar in South Texas to swap out engines. Starship is now back on the launch pad. Liftoff is set for Friday evening. A flawless launch and reentry will put SpaceX on the cusp of an orbital flight later this year. Ars will have a comprehensive recap story after the completion of the test flight.

India's first private rocket reaches orbit. Indian space officials celebrated the debut flight of Skyroot Aerospace’s Vikram-1 rocket, India’s first fully commercial satellite launcher, as a “grand success” Saturday after an on-target climb into a 280-mile-high orbit following liftoff from an island spaceport in the Bay of Bengal, Ars reports. The Vikram-1 lifted off from India’s primary spaceport on Sriharikota Island around midday local time. The launch was delayed more than a half-hour to resolve a last-minute technical problem. The countdown resumed, culminating in the command to ignite Vikram-1’s solid-fueled first stage booster to propel the rocket off the launch pad.

The Space Development Agency was established in 2019 to help speed up the deployment of US military space systems by sidestepping the Pentagon's traditional sluggish bureaucracy.
Seven years later, SDA is finally launching its first batches of operational satellites, just as the Pentagon plans to shutter the semi-autonomous agency and fold it back into the Space Force's procurement pipeline, newly reorganized under several program acquisition executives in a bid to streamline weapons buying.
SDA's fate is not a surprise, and lawmakers in both houses of Congress have backed the agency's closure in drafts of this year's National Defense Authorization Act.
Everyone seems to be launching and landing rockets these days.
Last week, China joined the club of countries that have launched an orbital mission and brought its booster safely back to Earth, which is just the beginning of public and private ventures in that country aggressively pushing into rocket reuse. Also in Asia, Japan's space agency has been conducting hop tests, and Honda recently performed vertical reuse tests.
In the United States, of course, SpaceX launches and lands reusable rockets every few days. Blue Origin, although its New Glenn booster is temporarily grounded, has also demonstrated the ability to both land and re-launch a large orbital booster. Other US companies, including Stoke Space, Rocket Lab, and Relativity Space, are all making credible progress toward partially or fully reusable rockets.

The First Nuclear-Powered Satellite is Now in Orbit
Tuesday marked a new chapter in the quest for novel power systems for spacecraft, with the launch of the world’s first satellite equipped with a commercial betavoltaic nuclear power system.
The City Labs Betavoltaic Orbital High-Reliability (BOHR) satellite was carried to space on board a SpaceX Falcon 9 rocket, and in the coming weeks will begin tests to determine whether miniature nuclear batteries can reliably generate electricity in space.
Designed primarily as a proof of concept, the first BOHR satellite will rely on conventional solar panels for its primary power system. However, the first-of-its-kind spacecraft also carries the company’s proprietary “NanoTritium” betavoltaic power source, which, according to the company, uses beta particles emitted during the radioactive decay of tritium that are converted into electricity.
In a statement, Peter Cabauy, CEO of City Labs, called this week’s launch “a historic step for commercial nuclear power in space,” adding that the BOHER satellite “demonstrates that safe, compact, and regulatory-approved nuclear power systems are ready for routine commercial deployment.”
“This capability enables persistent, always-on payload operations that are not constrained by sunlight or battery life,” Cabauy added.
Harnessing the Power of Beta Radiation
The innovative satellite was carried to space earlier this week as part of the recent SpaceX Transporter-17 mission.
“On Tuesday, July 7 at 12:12 a.m. PT, Falcon 9 launched the Transporter-17 mission to low-Earth orbit from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California,” read an update that appeared at the SpaceX website announcing the successful launch that carried the City Labs BOHR satellite to space.
“Transporter-17 was a dedicated smallsat rideshare mission,” SpaceX’s update earlier this week added. “There were 81 payloads on this flight, including cubesats, microsats, hosted payloads, and orbital transfer vehicles carrying eight of those payloads to be deployed at a later time.”
Following the satellite’s successful delivery to orbit, its power systems will begin testing the feasibility of beta radiation as a primary driver to produce electricity. In the past, radioisotope thermoelectric generators have been used to propel landmark space missions, such as Voyager 1 and Voyager 2. By contrast, BOHR’s beta radiation system does not rely on heat generated by radioactive decay, which allows for a compact power source that, if all goes according to plan, could one day be deployed in future missions to support spacecraft operating in environments where sunlight is limited. Such applications include the permanently shadowed craters on the Moon and future missions into the outer solar system.
Primarily, City Labs says a tritium-based system is also more beneficial than traditional nuclear fuels like plutonium since it emits relatively low-energy radiation. This, the company says, makes it easier to shield and safer to handle during spacecraft assembly and launch.
Challenges Ahead
The technology does face significant hurdles, however. One involves the fact that tritium is presently still one of the world’s rarest—and most expensive—radioactive materials. Right now, with only around 20 kilograms produced annually throughout the world, the limited quantity and exorbitant costs (current prices reach tens of thousands of dollars per gram) make large-scale adoption anytime in the near term a significant challenge.
There are also regulatory considerations, as noted in a news article released this week by the American Nuclear Society (ANS) following the launch. “In 2019, National Security Presidential Memorandum – 20 (NSPM-20) laid out updates to the process for launching spacecraft containing nuclear systems,” the article states.
“Now the Department of Transportation, which includes the Federal Aviation Administration (FAA), directs the coordination of various agencies to review the safety analysis for missions with nuclear components,” the ANS news brief added, noting that the FAA updated its launch regulations in 2020.
Despite the existence of a few hurdles and other considerations, the mission nonetheless marks an important milestone in the development of next-generation spacecraft power systems. If successful, BOHR could demonstrate that compact betavoltaic power sources are a viable complement to solar energy, opening new possibilities for long-duration missions in some of the darkest and most remote regions of the solar system.
The proliferation of nuclear power in space got a little more real Tuesday with the launch of a small satellite developed by a Florida-based company specializing in nuclear micro-power technology.
The satellite from Miami-based City Labs is named BOHR, short for Betavoltaic Orbital High-Reliability, and it launched on a SpaceX rideshare mission Tuesday alongside 80 other payloads. SpaceX's Falcon 9 rocket released the BOHR satellite into an orbit between 350 and 400 miles (nearly 600 km) in altitude.

Welcome to Edition 9.01 of the Rocket Report! Back in January, I wrote about the 20 launches and landings we were most excited about in 2026. The list included things that were, at the time, officially scheduled to occur this year. I also gave my own view of the probability of each of these events actually happening before December 31. Halfway through the year, we can only count one of the events as completed, and that was NASA's Artemis II mission in April. Many are now scheduled for next year, proving again that delays are a constant in the space industry. A couple of them—such as the launch of NASA's Roman Space Telescope—do appear to be on track to happen soon.

Swift Boost Mission reaches orbit. A pioneering commercial mission to reboost the orbit of NASA's Swift astronomy satellite launched early Friday after attempts earlier in the week were thwarted by bad weather and a technical issue. The Link servicing satellite developed by Katalyst Space Technologies soared to orbit on the tip of a Northrop Grumman Pegasus XL rocket that dropped from the belly of a modified L-1011 jetliner over the remote Pacific Ocean. Mission managers called off two launch attempts Tuesday and Wednesday due to poor weather around the L-1011's staging base on Kwajalein Atoll in the Marshall Islands. On Thursday, "a launch vehicle issue temporarily prevented teams from deploying the rocket" after takeoff of the L-1011.
