Voyager 1 probe to hit historic one light-day distance from Earth in 17 days — 49-year-old spacecraft travels 16 billion miles

The Voyager 1 spacecraft, which was designed for a five-year mission to observe Jupiter and Saturn, is about to reach a distance of one light-day from Earth after nearly 50 years in flight. According to NASA, the space probe will get to that marker on Nov. 18, 2026, at 5:16:07 a.m. EST, making it the most distant artificial object in history. The agency has now posted a countdown clock to mark the historic moment it becomes the first human-made object to reach that distance.

One light-day isn’t a span of time, but the distance it takes for light to travel in 24 hours. Since light travels at around 186,282 miles per second or 300,000 km per second, that’s a distance of about 16 billion miles or 26 billion kilometers. By comparison, the Moon is 238,855 miles (384,400 kilometers) from Earth, while our planet is 93 million miles (149.6 million kilometers) from the Sun.

Voyager 1’s estimated speed in relation to the Sun is 37,844.49 mph, which makes it pretty fast (but still not the fastest human-made object ever built — the Parker Solar Probe’s holds the record at 394,736 mph). Despite that, it will still take the spacecraft 49 years, 2 months, and 13 days to get to one light-day from Earth.

This is actually one of Voyager 1’s achievements, as NASA scientists have extended its lifespan by nearly ten times the length of its original mission timeline. It also hasn’t been easy for the space probe — in 2024, it suffered from a critical memory error, which engineers were able to fix after weeks of diagnosis. The distance has made repairing the spacecraft quite a challenge, as the latency at that time was already more than 22 hours, with round-trip communications taking at least 45 hours. Earlier this year, NASA had to use an emergency instrument shutdown procedure after an unexpected drop in power levels.

Experts estimate that the three radioisotope thermoelectric generators (RTGs) that power the spacecraft have enough juice in them to allow Voyager 1 to continue operating until the 2030s. So, unless it encounters a major issue, we can expect it to continue sending data back to Earth as it continues to travel through interstellar space. As the space probe continues its journey, its heading is set towards a star called AC +79 3888 or Gliese 445. This heavenly body is located within the Ursa Minor constellation, with the ship expected to pass within 1.7 light-years of the star in 17 light-years. But given that Voyager 1 only travels at 0.00564325% of the speed of light, we estimate that it will take the ship more than 300,000 years to reach its next destination.

USAF successfully tests dropping SpaceX Starfall cargo drop pods from space

The Air Force Research Lab (AFRL), the research and development arm of the US Air Force, has successfully tested Rocket Cargo capabilities, which would allow military units to resupply via cargo pods dropped from space. According to the AFRL’s X post, the cargo pods, which were onboard a SpaceX Starfall capsule, launched from the Cape Canaveral Space Force Station as part of the Bandwagon-5 “rideshare” mission carried by a Falcon 9 rocket. The capsule splashed down in the Pacific Ocean for this test, with the unit containing mission equipment like MREs, bottled water, a SATCOM-enabled tracker, spare batteries, and other equipment. The AFRL also fit-checked a UNI-PAC III life raft to see if it would fit inside the Starfall capsule for a potential test in the future.

The mission is a test of Rocket Cargo’s point-to-point delivery (P2D) capabilities, which should allow forces to resupply virtually anywhere in the world without needing to risk other assets like aircraft and aircrews, especially in areas where there is active combat.

With support from @SpaceX, the AFRL agile cargo pods were recovered after splashdown in the Pacific Ocean. Each pod contained representative mission equipment to study the effects of temperature, shock, and vibration of the cargo environments during launch and reentry. #Readiness https://t.co/yWoND13ur4October 26, 2026

“This was a critical achievement to demonstrate the potential of Rocket Cargo delivery for point-to-point rapid global mobility for the Future Force," AFRL Technology Transition Office director Adam Remaly said in a statement. "The cross-discipline collaborations and ability to unleash the speed of our defense industrial base are key to maximizing capability and winning the future.”

The Starfall capsule, which looks like a hockey puck, measures about 10 feet across and has a capacity of up to 2,200 pounds. It uses a carbon fiber heat shield to protect its contents during reentry and uses compressed gas thrusters for attitude control in flight. Finally, it deploys a parachute system to slow down the entire system for landing. While 2,200 pounds might already seem like a substantial capacity, the Air Force is reportedly hoping that it could increase the limit in the order of tens of tons, potentially allowing it to resupply ammunition, weapon systems, and even deploy vehicles from space. This would have to wait for the larger SpaceX Starship rockets, which are still in development, though.

Even though the latest test seemingly relies mostly on SpaceX technologies, it’s not the only company developing that capability for the U.S. military. Sierra Space, a subsidiary of the Sierra Nevada Corporation, is also working on the Ghost reentry vehicle and has already conducted test drops of the system from heights of 35,000 and 68,500 feet.

The capability to resupply troops across long distances without needing to rely on a long logistical tail is crucial for the U.S., especially as it faces a potential adversary in the Pacific. It’s also for this reason that the U.S. Navy has been experimenting with 3D-printing technologies, allowing it to print parts onboard carriers and at forward bases instead of waiting for shipments from across the ocean.

Russian military satellite closes from 200 miles to 3 miles of US radar craft aiding Ukraine

作者 Shane Downing
2026年10月19日 18:00

A Russian military satellite, Cosmos 2612, has closed to roughly 3 miles, from a previous distance of more than 200 miles, of the U.S.-owned radar satellite that operates in a fleet that supports Ukraine, Axios reports. The unapproved rendezvous in low Earth orbit, which astronomer Jonathan McDowell says may be the first of its kind, raises alarm in the West. The position change, which was likely not an accident as fuel is scarce, is probably a provocation and an attempt to spy on the satellite.

New TLEs show that K2612 made a manuever on Oct 16 and is now stationkeeping within 5 km or less of ICEYE X36. To my knowledge this is the first LEO rendezvous of two active satellites where the owner of one of the sats did not give approval.October 17, 2026

LeoLabs said in a statement Friday that the movement “appears to be a deliberate approach” toward ICEYE-X36, with uncertain intent and behavior that “warrants continued monitoring.” Roughly 3 miles is too close for comfort in satellite terms: there is no strict legal limit on how close satellites can get, but countries generally keep at least 6 miles (9.7 km) apart, University of Mississippi space law professor Aaron Brynildson told Axios. The approach was made without the owner’s consent, and Russia hasn’t said what the military satellite carries.

Some clues may come from the target’s operational purpose. ICEYE-X36 is a synthetic aperture radar (SAR) satellite which can image through cloud cover and at night. It was launched in March 2024 on a SpaceX Falcon 9. It’s registered to ICEYE US, the U.S. arm of the Finland-founded company. The satellite, which is in a roughly 545 km (339 mi) sun-synchronous orbit, is part of a fleet that has supplied Ukraine with information since 2022. This includes a deal earlier this year with a customer in Ukraine’s defense ministry, but a Ukrainian official told Axios it’s unclear whether ICEYE-X36 itself supports the country; ICEYE and the Defense Department declined to comment.

In May, the majority of the six military satellites Russia launched in April via a Soyuz-2.1b, Cosmos 2609–2614, shifted their orbits about 0.8 degrees to match X36’s orbital plane. Cosmos 2609 passed within 2.5 km (1.6 mi) on May 26. Cosmos 2612, on the other hand, drifted off X36’s plane by about 0.24 degrees by Sept. 30, up to about 28 km side to side, according to Greg Gillinger, a space analyst with Integrity ISR.

Then, Cosmos 2612 made separate burns from Sept. 30 through Oct. 16 to match altitude, eccentricity, and orbital period, Dutch satellite tracker Marco Langbroek wrote. By Saturday night, he estimated from public orbital data, it was within “a few hundred meters or possibly (much) closer.”

These movements appear deliberate and cost a lot of fuel, which the Center for Strategic and International Studies calls “a limited resource on a satellite.” Close-proximity work can be benign, it says, but policymakers should assume the Russian satellite “could take an action that threatens the commercial satellite,” and the U.S. and Europe should decide how to respond to any hostile act in space and make a statement on the decision. Back in July 2020, Russia’s Cosmos 2543 released an object at up to 186 m/s (416 mph) relative to itself, an action which was condemned by the U.S. and U.K.

Intent was less clear earlier this year, when McDowell told Meduza the orbital data showed no sign of the stable, close distance that tracking ICEYE-X36 would require. Now, he says it is an unapproved meeting and is not alone. Gillinger says the setup “removes any remaining doubt for me that Cosmos 2612 is interested in ICEYE X36.” Langbroek adds that “I was skeptical” at first but now calls it “completely non-consensual,” though he cautions it would be difficult to pin any X36 failures on 2612’s actions.

In a Reuters report less than two weeks ago, ICEYE CEO Rafal Modrzewski said the company moved its satellite after May, only to draw more Russian maneuvers, which Germany’s Space Command head, Maj. Gen. Michael Traut, described as “chasing.” Belinda Marchand, chief scientist at U.S. space intelligence firm Slingshot Aerospace, added that the moves may have been meant for surveillance, to prepare for future interference, or to signal capability. Western officials reportedly describe such trailing as a way to gather intelligence and test the West’s tolerance.

No statement from Russia is on record. Gillinger also told readers to “watch Cosmos 2611 and 2613, whose planes are converging on ICEYE X37’s,” with crossings expected around Nov. 6 and Nov. 15.

US military-backed cargo pod promises 90-minute orbital delivery anywhere on Earth, 10-ton Ghost vehicle gets first real-world test

2026年10月11日 18:00

A U.S. military-backed company plans to deliver a payload to any point on Earth within 90 minutes by prepositioning assets in space and then calling down delivery vehicles as needed. Sierra Space, a subsidiary of the Sierra Nevada Corporation, has successfully completed two test drops of its Ghost reentry vehicle while carrying a bottle of whiskey and a software-defined radio. According to Aviation Week, the test was conducted using high-altitude balloons that dropped it from 35,000 feet and 68,500 feet.

While this test isn’t as exciting as SpaceX rockets landing on a platform at sea, it’s still an achievement for the team working on the project, as it’s the first test of the vehicle in two years. This demonstration is part of the U.S. Space Command’s Apollo Nexus training exercise, which aims to demonstrate the needed synchronization of multiple units in complex operations.

The test’s payload isn’t just two random items, either. They’ve been specifically selected to show that liquids and sensitive electronics could survive part of the trip back to the surface. “We were able to safely demonstrate that and prove that we could come through all of those environments and then be recoverable in a certain period of time by the team on the ground,” Sierra Space senior vice president Erik Daehler told the publication.

It should be noted that these cargo units aren’t designed to be launched by rockets from another side of the world to be delivered to frontline forces as needed. Instead, they’re designed to stay in orbit for up to five years and then be called down to troops as needed — similar to how Orbital Depots drop down from the sky when called by an SCV in StarCraft II. “Getting something into theater to the warfighter when they need it is critical,” Daehler added. “If you’re in a denied area where you couldn’t get a C-17 or a C-130 to be able to drop into the theater, space is a perfect logistics node.”

The company says that Ghost can deliver its payload to any point on Earth within 90 minutes of getting called down. However, since it is based in space, the military would have to anticipate what supplies are needed, launch them, and keep them in orbit for up to five years. This is similar to how the U.S. pre-positions supply and cargo ships in remote bases across the world like Guam and Diego Garcia, so it could easily deploy materiel where it’s needed. The Ghost is a seemingly small unit, though, with a capacity of just five to ten tons, so it won’t be able to deploy tanks or artillery pieces across the world. Still, it’s a useful device for dropping equipment, ammunition, and supplies, like this in-house assembled drone or microwave counter-drone system, to units that need them without having to risk assets and aircrew.

China launches 'Supercomputing-1' AI satellite as orbital data centers gather momentum

作者 Etiido Uko
2026年9月23日 18:30

China has launched nine satellites — including its first integrated “rocket and satellite” AI computing project — as part of its push to put AI computing in orbit. According to a Digitimes report, the Kinetica 1 Y18 rocket, operated by Chinese commercial launch provider CAS Space, lifted off on September 20, carrying the nine satellites to their planned orbits.

The payload of greatest interest is the “Supercomputing-1” satellite, developed by Chinese AI computing infrastructure company S-AIDC. Also known as the S-AIDC-1, the satellite is designed to capture and process Earth-observation data in orbit instead of sending data back to terrestrial data centers. Keeping the processing local is meant to cut cross-regional data processing times from hours to minutes. The satellite features both a high-res optical payload and the image-processing AI computer.

According to Digitimes, the launch highlights China's efforts to develop orbital computing as part of a “broader integrated computing network.” In early June, the Chinese government approved the Space Computing Industry Innovation Center, which aims to bring together rocket and satellite manufacturers, semiconductor fabs, and AI tech companies to build a space computing network. A couple of factors are driving this spike in the development of off-planet computing, foremost among them being the AI boom.

The demand for artificial intelligence has spurred the construction of numerous data centers to house AI accelerators. These data centers, some of which can house hundreds of thousands of accelerators, consume unprecedented amounts of electricity, placing significant strain on the grid. This, along with land use, water consumption for cooling, and noise, has fueled growing anti-data sentiment, with local residents blocking $68 billion worth of new data center projects in Q2 2026.

Despite numerous economic and practical challenges, space might offer an alternative with unlimited area, access to solar power, constant cold conditions, and a dead-quiet vacuum. These advantages have made orbital computing a serious topic of discussion. SpaceX is leading the charge with the AI1 satellite, a proposed orbital data center that will deliver 150 kW of peak compute power. The company aims to achieve 1 GW per year of space AI compute by 2027 and has begun constructing the 11-million-square-foot Gigasat facility that would manufacture the 6,000 satellites required to meet this goal.

Beyond the large-scale serving of AI models, putting edge compute capacity in space is already useful for a range of applications. Earth-observation satellites can process images onboard to identify wildfires, storms, floods, ships, or other objects of interest, sending only the useful results back to Earth instead of dumping enormous amounts of raw data to ground stations. The same approach can speed up weather monitoring, disaster response, communications, and even the management of satellite constellations, where spacecraft could make more decisions independently rather than waiting for instructions from Earth.

The launch of a single satellite with edge AI capabilities on board is a far cry from an entire orbital data center, but China's approach could prove to be a more practical and immediate application for advanced computing capabilities in orbit.

Russian Starlink rival flounders after entire batch of satellites fails to reach operational altitude — many of the 16 launched hit less than half their 870km target, and two are already falling back to Earth

2026年9月2日 18:00

The entire second batch of Russian Rassvet satellites have failed to reach their target operational altitudes, reports the U.S.-based Institute for the Study of War (ISW), citing data from live satellite tracker N2YO. They were supposed to reach an operational altitude of 870 kilometers, but “many of these satellites ended up at altitudes between 300 and 400 kilometers, and some are experiencing orbital decay,” notes the source. Moreover, two of the second batch are already on their fiery return journey to Earth.

We’ve been watching the progress of Rassvet, the Russian homebrew alternative to Elon Musk’s Starlink, with some interest in 2026. Russia accelerated its state-funded satellite internet development after access to Elon Musk’s solution was removed, when a new whitelist user-access system was implemented (after some prior ineffective Russia-blocking efforts).

Developed by a private aerospace outfit called Bureau 1440, the Russians aim to expand the Rassvet constellation to 900 satellites by 2035. There’s still a very long way to go to hit that target. In March we reported on the launch of the first 16 Rassvet satellites. In June we followed up with news that one of them, dubbed ‘Object 4,’ had dropped out of orbit already. The ISW now says that only 12 of the first batch actually reached their anticipated altitudes. Running at lower altitudes will mean reduced lifespans as the lower-altitude satellites require more fuel.

Russian ‘Starlink Rival’ established with 16 satellites launched

The second set of 16 Rassvet satellites was launched in mid-June. Reports indicate that none of the second batch have reached their anticipated altitudes, so things don’t look good for this project. The ISW reckons that Russia will need at least 200 to 300 fully operational Rassvet satellites to achieve stable connectivity over Ukraine 24/7. Rassvet as it stands offers two up-to-90-minute connectivity windows a day over Ukraine. Meanwhile, Ukraine’s strategists surely have Russian satellite production and launch facilities on targeting lists. It looks like Russia’s interim target of 250 operational Rassvet satellites sometime in 2027 will have to be revised.

Europe expands its Starlink rival to 348 satellites as IRIS² moves into implementation — €15.6 billion network will boost EU government capacity by 60%, with launches starting in 2029

2026年8月10日 17:30

The European Commission and the SpaceRISE consortium signed an implementation agreement on Friday, August 7, to roll out Europe’s IRIS² satellite constellation, moving the project from the planning and negotiation stage into full-scale deployment. According to an official press release, the agreement adds 66 satellites to the planned constellation, bringing the total to 348 — 330 satellites in low Earth orbit and 18 in medium Earth orbit — with first launches targeted for 2029.

The expansion is intended to substantially increase the network’s government and defense capacity. According to the Commission, the revised architecture will provide 60% more secure governmental communications capacity within the EU and 54% more globally. The existing satellites in the baseline constellation will also receive additional functionality and stronger security features, while the 66 new spacecraft will operate in higher low Earth orbit.

IRIS² — short for Infrastructure for Resilience, Interconnectivity, and Security by Satellite — is the European Union's flagship secure-connectivity constellation, intended to give European governments an autonomous alternative to foreign networks such as SpaceX's Starlink and Amazon's Leo. The Commission signed a 12-year concession contract for the program in December 2024 with the SpaceRISE consortium — a grouping of European satellite operators SES, Eutelsat, and Hispasat — which is building and operating the system under a public-private partnership alongside manufacturers including Airbus Defense and Space, Thales Alenia Space, OHB, and Aerospacelab.

Once operational, the multi-orbit network will deliver sovereign, encrypted connectivity to authorized governmental users across EU member states and participating non-EU countries, currently Norway and Iceland, for use in emergency response, critical infrastructure protection, and security missions, with capacity also earmarked for citizens in areas with poor coverage.

When the concession contract was signed in December 2024, IRIS² carried a price tag of €10.55 billion ($12.19 billion), funded by the European Union, the European Space Agency, and the SpaceRISE consortium. The accelerated timeline and larger constellation have pushed that figure higher, with the consortium's partners now putting total planned investment above €15.6 billion ($18.03 billion), drawn from the EU budget for 2028–2034, ESA, the consortium partners, and member states. Several countries have already committed, with Poland and Hungary pledging €656 million ($758 million) and €500 million ($578 million), respectively, while Spain has announced between €1.6 and €2 billion ($1.85–2.31 billion).

IRIS² is frequently framed as Europe's answer to Starlink, as they are both satellite constellations aimed at providing connectivity to dead zones. However, the primary purpose of the 348-satellite-strong constellation is more niche. The EU wants an independently controlled communications system — mainly for government and emergency use, but also for civilian applications — that can remain available when terrestrial networks fail, or when access to foreign-operated satellite systems becomes politically or strategically uncertain. On the other hand, Starlink’s growing 10,000-satellite constellation is a mainly commercial, privately owned company selling broadband to consumers worldwide. It is now also running satellite-to-phone internet services through Starlink Mobile.

Intel's proposed orbital data centers would manage thousands of simple LEO satellites —two-tier network puts the brains of satellite constellations in higher orbit

2026年8月8日 19:45

An Intel patent application published on August 6, spotted by Patentlyze, describes an orbital data center architecture that moves some of the computing used to operate massive satellite constellations off the ground and into space. The architecture proposes a two-tier satellite network in which a small number of more powerful satellites in higher orbits manage large constellations of relatively simple satellites in low-Earth orbit, handling much of the computing and constellation coordination normally performed by data centers and network operations centers on the ground.

The application, US 2026/0230175 A1, is a continuation of an earlier Intel filing that was granted as US 12,542,604 B2 in February.

Intel’s proposed architecture is a different proposition from the orbital AI data centers now being pursued by companies such as SpaceX and Google, which aim to move AI compute itself into low-Earth orbit. SpaceX’s planned AI1 satellite and Google’s Project Suncatcher both envision running large-scale computing workloads in space, with the resulting data beamed back to Earth over high-bandwidth optical links. Intel’s orbital data centers, on the other hand, are designed primarily to serve the satellite network itself, acting as higher-orbit compute and control hubs for the much larger constellations operating below them.

In large LEO constellations such as Starlink, Telesat Lightspeed, and Amazon’s Project Kuiper, thousands of satellites are constantly moving relative to one another and the Earth. While the satellites perform their individual tasks, the network itself still has to determine how traffic is routed, which satellites and links should communicate, how spectrum is allocated, and how the constellation responds to failures, interference, weather, and other changing conditions. Much of that network planning and control processing is traditionally handled by computers on the ground, with routing and operational instructions calculated at terrestrial network operations centers and then transmitted back up to the satellites.

Intel says that this constant dependency on terrestrial infrastructure delays time-sensitive decisions, increases reliance on ground stations, and makes management harder as constellations grow into the thousands of satellites. Intel’s solution is to move part of that control and compute layer into orbit. Its architecture places more powerful satellites — which contain much more compute and storage capability than the individual LEO satellites — in Medium Earth Orbit (MEO), Geosynchronous Earth Orbit (GEO), or highly elliptical orbits, where they can maintain a broader and more persistent view of the LEO constellation below and take over tasks such as routing, mission planning, scheduling and network coordination without continually sending those workloads back to Earth.

The proposed setup does not eliminate the need for ground stations. It just keeps satellite network control processing in space. Intel specifically describes moving mission planning and scheduling operations into orbit. The company also argues that offloading heavier network-management tasks to a smaller number of powerful satellites could allow operators to build simpler, cheaper LEO spacecraft. Under current architectures, individual satellites still have to actively participate in network-control functions, requiring additional onboard compute and communications hardware. There’s currently no indication that Intel is actively building the satellites.

NASA modded space station's laptops so everyone could use the same charger — standardizing ISS chargers eliminated useless weight and reduced failure points

2026年8月8日 18:30

NASA ensured that all laptops destined for use in the International Space Station (ISS) had the same power connector. Engineer George Roush, who has a certain fondness for space tech, recalled details of this laptop modification earlier this week. Standardizing on a single ‘cannon plug’ meant that instead of requiring a multitude of different chargers, ISS visitors could plug into the onboard DC power outlets in a standard fashion. Roush took the photos shared below during a visit to the NASA Stennis visitor center.

Since you all care (thank you for that, by the way) here's the answer: That's not an ethernet port at all! It's a modem port! Modem ports are useless on the ISS. So, NASA replaced this useless port with a new power port. Taking 9 different laptop chargers into space sounds… pic.twitter.com/ZLcqcEOHVfAugust 2, 2026

Laptops destined to be used on the ISS would have their modem ports removed and replaced by the cannon plug you can see in the engineer’s photos. Of course, modem ports would be useless on the ISS, so that’s why they would be replaced with this modification. In space, every gram, every connector, and every failure mode matters, which makes this power standardization a smart move.

Sources indicate that Lockheed Martin was contracted to make these modifications to the ThinkPads and other machines that ended up being taken to space. Roush also discusses networking/comms on the ISS, which relied on the MIL-STD-1553 system, rather than Ethernet.

Laptops with built-in telephony modem ports certainly date this story. However, we must remember that the ISS was constructed in the late 1990s when modems were still essential for PCs. The first crews docked in 2000.

Original web sources are vanishing

When refreshing his knowledge about this laptops-in-space mod, the space enthusiast and engineer was struck by another realization, which he found troubling. The NASA Stennis visitor center had barely any information about the laptops or the cannon plug modification that was on display.

Turning to some online resources he remembers referring to previously, Roush noticed a lot of them had disappeared. “The old internet is dying, and with it, we risk losing a lot of useful history,” said the engineer. “I fear that the false belief of the 'eternal' internet will cause otherwise recorded history to be lost when the servers shut down.”

Though some resources may still be able to be unearthed via the Wayback Machine, it seems perilous that so much web history is archived by a charity (The Internet Archive). In May, we reported that the internet is getting harder to archive because the AI boom has caused a storage crisis, with both NAND and mechanical drives facing shortages. This means skyrocketing storage bills to support the activities of the Wayback Machine.

HP replaced all the ISS laptops in April 2026

The astronauts in the ISS aren’t still using old modded laptops like the one showcased in the NASA Stennis visitor center. The latest updates came in April this year, with over 100 HP Z Workstations packing a mix of Core Ultra 9 processors and RTX Pro Blackwell graphics sent into orbit.

HP talks about putting these PCs through two years of rigorous testing ahead of deployment. We don’t get much in the way of technical info from its release, but again, it was recognized that a single power standard was important. The computer maker supplies universal AC/DC power adapters with its latest crop of space laptops that are specially designed to function on both the ISS and Earth.

Errant SpaceX rocket stage set to smash into the moon at 5,400 mph, seven times the speed of sound — NASA and South Korean orbiters prepare to track 3-ton TNT impact

2026年8月2日 23:44

The upper stage of a SpaceX rocket that delivered two lunar landers in early 2025 is set to come crashing down on the lunar surface several months after it ended its mission. According to Japan Today, the large piece of rocket debris is expected to hit the moon at an estimated 5,400 mph or 8,690 kph, which is seven times the speed of sound.

While a piece of debris hitting the moon might seem like an inconsequential event for most people, scientists and astronomers are keeping a close eye on it because this will be one of the few times that an object will impact the moon while being observed. NASA’s Lunar Reconnaissance Orbiter and South Korea’s Danuri lunar orbiter will take before-and-after photos of the impact site, while the latter will also fly close to the stricken SpaceX rocket a few minutes before it begins its final descent.

NASA has previously deliberately crashed objects on the moon — it did this with sections of the Saturn V rocket and discarded Lunar Landers to conduct seismic experiments during the Apollo missions in the 70s. It repeated the experiment in 2009 with its LCROSS mission, where it crashed the probe near the south pole of the moon in search of ice.

What interests researchers this time is how the impact will affect the surface of the moon, which is expected to deliver energy that’s equal to about three tons of TNT. Even though this might seem like a huge amount of energy, we likely cannot see the actual crash from Earth. But because the moon does not have wind or an atmosphere, the ejected material could stretch for miles and be visible on telescopes.

“The gravity on the moon is low and there is no wind to blow the dust away,” said Benjamin Fernando of the Los Alamos National Laboratory. “Part of the reason for our interest in this event is to figure out how much of a hazard debris impacts pose to future astronauts.”

Space debris is not a major concern for the moon as it is for our planet at the moment, but this might change in the near future. As the U.S. and China are locked in a space race to see who will be the first one to land on people on the moon again after more than half a century, there will soon come a time when operators cannot just leave their rocket debris in an orbital decay, lest it come crashing down on their settlements and data centers.

Space Force gets first mobile high-powered electromagnetic beam weapon to cripple enemy satellites — plans to deploy 32 ‘Meadowlands’ units to detect, deny, disrupt, and degrade hostile space assets

2026年7月8日 18:00

U.S. Space Force Combat Forces Command has announced that the first Meadowlands Counter Communications System (CCS) has been delivered for operational duty. This is a powerful new electromagnetic warfare (EW) device in a wheeled mobile and air-transportable form factor, designed to detect, deny, disrupt, and degrade adversary capabilities around the globe and in space. To be clear, Meadowlands isn’t a laser, microwave, particle, or plasma weapon. Instead, its highly targeted electromagnetic warfare abilities rely on a muscular array of directional antennas and high‑power RF amplifiers.

Our acquisition and operational collaboration wins again – this time for the operational acceptance of Meadowlands. The #USSF electromagnetic warfare platform now better detects, denies, disrupts, & degrades adversary capabilities. More: https://t.co/zRwJrmOd9g pic.twitter.com/WeuUhUitYlJune 30, 2026

“We have exceptionally trained and skilled electromagnetic warfare professionals who are highly motivated and excited about integrating this new Meadowlands capability,” said U.S. Space Force Lt. Col. Ryan Skilling, 4th Electromagnetic Warfare Squadron commander. “This upgraded system enables us to more effectively and efficiently support the joint scheme of maneuver across the continuum of conflict.”

Meadowlands arrives to provide a critical upgrade to the existing Counter Communications System (CCS) 10.2, notes Space Force. The new system’s advances are described as a “huge milestone” in capability, as well as being lighter, more compact, and more easily transportable. Meadowlands is set to be part of a robust toolkit that will help deliver “spectrum dominance” to the U.S. Space Command and Department of War.

The efficacy of systems like Meadowlands has already been demonstrated in joint force applications like Operation Midnight Hammer. In this example, EW systems were used to successfully create a “silence zone” over Iran for hours to ensure secure bomber ingress and egress during that operation. Meadowlands units can operate in both forward austere environments and from secure rear echelons.

In addition to silence zones, typical EW tasks Meadowlands will be used for include interference with enemy satellite functions, and jamming uplink and/or downlink signals. More cunningly it can change or corrupt data packets, initiate feedback loops, and spoof enemy assets.

While it celebrates the arrival of its first operational next-gen CCS, Space Force Combat Forces Command intends to build its Meadowlands fleet to 32 units in due course.

SpaceX vaporizes 260 Starlink satellites in six months using Earth's atmosphere — new environmental concerns emerge over burning 2,700-pound orbital data centers, FCC seeks to exempt satellites from regulations

2026年7月6日 00:00

SpaceX has confirmed in a semi-annual report submitted to the Federal Communications Commission (FCC) earlier this month that it disposed of 260 Starlink satellites between December 2025 and May 2026, intentionally vaporizing them via re-entry into the Earth's atmosphere. According to the report, 176 of these satellites belonged to the first-generation Starlink constellation, with the rest belonging to the second generation. An additional 349 satellites were decommissioned within that 6-month period and will be disposed of in the coming months.

SpaceX’s Starlink operates a huge constellation of over 10,000 satellites as of the time of this report, even as the company plans for Starlink Mobile, which will provide satellite internet directly to mobile phones. However, each of these satellites has a lifespan of about 5 years, a somewhat intentional setup to allow swapping for newer versions, after which their fuel depletes. When this happens, the satellite is programmed to use its remaining fuel to perform a controlled de-orbit. It lowers its altitude and plunges into Earth's atmosphere, where extreme friction completely incinerates 100% of the spacecraft.

The constellation is so large and varied that Starlink reportedly disposes of multiple satellites daily. It removed more than 472 satellite links from orbit between December 2024 and May 2025. Retrieving the deorbited satellites — which weigh roughly 573 to 650 pounds (260 to 295 kg) for first-generation units and 1,764 to 2,756 pounds (800 to 1,250 kg) for second-generation units — is technically impractical and financially unviable, according to the company. Hence, the incineration technique.

While Starlink’s disposal approach disintegrates 100% of the spacecraft, leaving behind no falling debris, it has raised concerns about its effect on the atmosphere. Researchers have urged further studies and regulations on the environmental impact of satellites. The FCC has long excluded satellites from environmental reviews, reportedly out of concern that regulations might slow the space race. Any regulation would likely be under the National Environmental Protection Act (NEPA). However, the FCC is officially proposing “that space-based operations be excluded from NEPA because they are ‘extraterritorial activities’ with effects located entirely outside of the jurisdiction of the United States.” The proposal is yet to be approved.

SpaceX has a multi-phased goal to eventually deploy up to 42,000 Starlink satellites into low-Earth orbit and obtained FCC approval for 7,500 additional Starlink Gen2 satellites in January. Meanwhile, the company has unveiled plans for its A1 satellite orbital data center, with a 120 kW compute payload. SpaceX is currently building an 11-million-square-foot Gigasat manufacturing facility for these satellites.
