The central star-forming region of M82
Click for original. For original of inset go here.

Cool image time! The picture to the right, cropped, reduced, and annotated to post here, was released today by the Hubble Science team. It shows the central star-forming core of the galaxy M82, only about 12 million light years away and long known as a “peculiar” galaxy by earlier research from the 20th century. For this reason I used the 1963 optical image taken by the 200-inch Hale Telescope at Palomar in California as the inset, showing the entire galaxy. At the time the data only suggested some major energetic events were occurring in the galaxy’s core, as indicated by what looked like filaments shooting out from that core at right angles to the plane of the galaxy.

Data since then, from Hubble and Webb and other space telescopes, have revealed that this galaxy, which some have nicknamed the “Cigar Galaxy”, is forming stars at a prolific rate.

Forming stars 10 times faster than the Milky Way, the Cigar Galaxy is what astronomers call a starburst galaxy. The intense starburst period that grips this galaxy has given rise to super star clusters in the galaxy’s heart. Each of these super star clusters contains hundreds of thousands of stars and is more luminous than a typical star cluster.

The red indicates the dust that permeates the galaxy. The blue comes from the radiation emitted from the clusters near the center, illuminating and ionizing that dust.

Bubbling lava frozen in a Martian crater

Bubbling lava frozen in a Martian crater
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 23, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). This one-mile-wide unnamed crater was a featured image last week by the science team. As noted in the caption, written by Chris Okubo of the U.S. Geological Survey:

This area was covered by a large flood of lava, which we see as the generally flat areas surrounding the crater. As the lava flowed across, some of it flowed into this crater through a low spot along the crater rim.

Once in the crater, the lava heated ground water or ground ice in the floor, causing the water to boil and turn into steam. This steam then exploded through the overlying lava and created small, ring-shaped formations. These are called ”rootless cones,” and they record the presence of ground water or ground ice in the crater floor at the time of the lava eruptions.

In other words, when this crater was flooded with hot lava, it was filled with ice or water. That fact is significant because of the crater’s location, as shown in the overview map below.

Russia further centralizes and consolidates its shrinking space sector

9:43 am

Roscosmos: a paper tiger
Roscosmos: a paper tiger

Russia’s state-run TASS press agency today announced that the operations of much of its space sector has now been moved to a newly completed centralized facility on the west side of Moscow.

Over 30 enterprises of Russia’s rocket and space industry, based in Moscow, will move their production sites to the newly created National Space Center, Roscosmos chief Dmitry Bakanov said. “We now have a single platform, where 35 enterprises will be concentrated in one area,” Bakanov said in the National Space Center, visited by Russian President Vladimir Putin on Saturday.

The National Space Center opened in Moscow on Saturday. A complex of building with the total area of 276,000 square meters, is located in the West of Moscow. It’s a joint project of the Moscow Government and Roscosmos.

Sounds neat, eh? In fact, this illustrates how Russia’s space sector is declining. First, Putin in the 2000s centralized the entire industry into a single corporation, Roscosmos, run by the government. That Soviet-style top-down structure eliminated competition and acted to block new companies from forming.

Second, when Russia invaded the Ukraine in 2022 Roscosmos lost billions in revenue when its international customer base cancelled all their contracts and boycotted the country.

Consolidating all these “companies”, which are simply divisions of Roscosmos, into this one facility might save money, but it prevents independent action and competition. It also indicates Russia’s lack of cash.

Most importantly, this move presages the eventually shutdown of many of Russia’s space operations when ISS is retired. Russia has said it is building a new station, but its ability to launch anything new has been abysmal in the 21st century. Routinely it announces new projects which never fly. There is no reason to expect its proposed space station to be anything different.

Progress docks safely with Zvezda module at ISS

9:24 am

ISS as of today
ISS as of today. Click for original.

In what is increasingly a worrisome procedure, Russia’s just launched Progress freighter successfully docked with the aft port of the Zvezda module at ISS this past weekend, bringing with it more than 5,000 pounds of supplies and research equipment.

The image to the right, annotated additionally by me, shows the present configuration of spacecraft at ISS. The concerns center on the stress fractures that have been found in the Zvezda hull, fractures that have caused the air leak on ISS and are believed attributable to the many dockings to the module since its launch in the late ’90s, as well as the module’s age. It was first built in the late ’80s, making it almost four decades old.

For recent dockings, NASA now closes the hatch between the Russian and American halves of the stations, just in case Zvezda experiences a catastrophic failure. The Russians seem less concerned, but nonetheless they also take extra care during dockings. It is my understanding their astronauts prepare their Soyuz capsule as a lifeboat and immediately escape during these operations.

Starlink down for about an hour last night

8:53 am

According to several major news sources, Starlink was down for about an hour last night globally, impacting several tens of thousands in the U.S. alone.

More than 37,000 US users were reporting issues with the internet service Monday at 12:30 a.m. ET, according to the website Downdetector.com. By 1:30 a.m., that number had fallen into the hundreds. The internet service owned by Musk’s SpaceX stopped working on “the entire frontline in Ukraine” around 7:30 a.m. Kyiv time (12.30 a.m. ET), said Maj. Robert “Magyar” Brovdi, the commander of Ukraine’s unmanned systems force, on Telegram. As of 8:00 a.m., service was gradually being restored, he said.

I link to CNN, but numerous other outlets thought this story significant enough to give it front page coverage. That this is considered news, however, illustrates perfectly how well Starlink functions normally. A brief outage lasting less than an hour makes the cover of every news outlet in the world, because normally Starlink works without problems for its more than six million subscribers.

SpaceX has not as yet provided any information about the cause of the outage. I suspect we are seeing the result of a hacker attack, possibly by Russia, but that is pure speculation. Even if not, it is in SpaceX’s interest to outline in detail what happened. This has been its policy in the past, but in the previous outage in July the company was not forthcoming. That lack of transparency has not served the company well.

Space station startup Vast endorses NASA’s new strategy that no longer requires a continuous human presence in space

The American space stations under construction
The American space stations under development

Officials from the space station startup Vast revealed at a conference last week that they endorse NASA’s new strategy that, not only no longer requires the commercial stations to immediately establish a continuous human presence in space, will also award multiple development contracts to the commercial stations.

Speaking Sept. 11 at the Global Aerospace Summit, Max Haot [chief executive of Vast] endorsed NASA’s new strategy, announced more than a month ago, that calls for multiple Space Act Agreements to support development leading to a four-person, 30-day demonstration mission. “We think it’s really the right direction,” he said, noting it accelerates the award timeline. NASA said in a draft solicitation this month it expects to award multiple funded agreements by April 2026, months sooner than under earlier plans.

The original plan had been to choose at most two, but likely only one of the four consortiums/companies that are developing station proposals. The winner would have gotten a big contract that would have also required it push hard for continuous full time occupation, from day one.

The new plan will instead award smaller development contracts to as many as three of the four station projects, aimed at getting them off the ground and operating, even if astronauts only fly in them intermittently. Eventually the hope is that their capabilities will expand quickly to permanent occupation, especially if they start earning revenue from the private sector, outside NASA. In fact, the smaller government contracts will force them to seek investment and profits elsewhere.

SpaceX launches Northrop Grumman’s Cygnus freighter to ISS

8:13 pm

SpaceX today successfully launched Northrop Grumman’s Cygnus freighter with more than five tons of cargo, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its fourth flight, landing back at Cape Canaveral. The two fairing halves completed their 3rd and 6th flights respectively. Cygnus is expected to be berthed to ISS using the robot arm on September 24, 2025. This is also the first flight of the stretched version of Cygnus, capable of carrying more cargo.

House committee support for threatened NASA missions is actually quite questionable

9:26 am

According to a House appropriations committee spending bill that it approved this week, it appears on the surface that it is canceling the proposed 24% cut by Trump to NASA’s budget as well as endorsing continued funding for some threatened missions. A close look however suggests this congressional support for NASA is somewhat superficial, and might actually be ephemeral.

The key is the language of the bill. From the link above:

The bill was largely unchanged from what the CJS [commerce, justice and science] subcommittee approved July 14. It includes $24.838 billion for NASA, nearly the same as the $24.875 billion the agency received in fiscal 2024 and 2025, and far above the $18.8 billion the administration proposed for fiscal 2026 in May.

Members adopted a manager’s amendment, a package of noncontroversial changes and corrections, on a voice vote. That amendment also made additions to the report accompanying the bill. The report includes language expressing support for several NASA missions targeted for cancellation, including the Chandra X-ray Observatory, the Juno mission at Jupiter and the New Horizons mission in the Kuiper Belt.

The report does not specify funding levels for those missions, but the “continues support” language signals to NASA that it should fund continue operations within the agency’s science budget. [emphasis mine]

It is the vagueness of this language that suggests the support is ephemeral. The courts recently have consistently ruled that if Congress doesn’t specifically mandate spending on a project, the White House is free to move money around as it sees fit. By not expressly outlining funding for Chandra, Juno, and New Horizons, these congressmen are playing a shell game, whereby to their constituents they can point to this vote and claim they wholeheartedly supported NASA and these missions. At the same time, they also appear to be allowing Trump the freedom to go ahead and shut the missions down, as his budget has already proposed.

None of this is yet real. The bill still must be passed by the full House, as well as the Senate. It then has to be signed by Trump. A lot of changes would happen in that process.

Either way, it appears that within the House at least, there is some movement to at least make some budget cuts possible. The sad thing is that the House is not actually cutting the budget, even as it is allowing Trump a way to cut these relatively inexpensive on-going missions. Considering the debt, it would have been much better had the committee actually trimmed NASA’s budget, even a little, while at the same time allocating specific funds to keep these very cost-effective missions alive.

Italian rocket company Avio commits $469 million to expand operations

8:59 am

The Italian rocket company Avio, which owns the Vega-C rocket, today announced that is has approved a $469 million fund to expand its manufacturing capabilities, including building a production facility in the United States.

Announced on 12 September, the capital raise is part of a new ten-year business plan targeting an average annual growth rate of about 10% in turnover and more than 15% in core profit (EBITDA). This growth will be driven by a higher Vega C launch cadence, the introduction of Vega E, continued participation in the Ariane 6 programme, and the construction of a new defence production facility in the United States, which is expected to be completed by 2028.

The management of Vega-C had previously been controlled by the European Space Agency’s (ESA) commercial arm, Arianespace, which had owned and operated all of Europe’s rockets. ESA however is eliminating that commercial arm, shifting from the government-run model to the capitalism model, whereby it simply acts as a customer buying services from the private sector.

As part of that shift, Avio is in the process of taking back its Vega-C from Arianespace. Beginning next year it will be marketing the rocket directly to customers. This major investment reflects this change. The company is now free to pursue profits wherever it can find them, and it appears it wishes to market itself aggressively to American satellite companies as well as its defense industry.

Russia launches Progress to ISS

9:24 am

Russia today successfully launched a Progress freighter to ISS, its Soyuz-2 rocket lifting off from the Baikonur spaceport in Kazakhstan.

The freighter will dock with the aft port of the Zvezda module in two days. When it does so, expect NASA to require its astronauts to close the hatch between the American and Russia parts of ISS. The agency has real concerns about the stress fractures in Zvezda’s hull that are the cause of the station’s air leaks, and fears it could at some point fail catastrophically during a docking. The odds of this happening are small, but they are larger than they should be.

SpaceX still leads the rest of the world in successful launches, 115 to 91. The company has another launch scheduled for later today.

NASA bans Chinese citizens from its facilities or operations

9:09 am

Earlier this week NASA moved to block Chinese citizens with visas from having access to its facilities as well as its entire operations, citing security concerns.

“NASA has taken internal action pertaining to Chinese nationals, including restricting physical and cybersecurity access to our facilities, materials and network to ensure the security of our work,” NASA press secretary Bethany Stevens said on Wednesday. According to Bloomberg, Chinese nationals had previously been allowed to work as contractors or students contributing to research, although not as staff.

But on 5 September several individuals told the outlet they were suddenly locked out of IT systems and barred from in-person meetings. They spoke on condition of anonymity.

Though both the Chinese press and the leftist news outlet above (The Guardian) whine about this move, it makes great sense, and should have been done years ago. Though I am sure most of these Chinese citizens are not spies, China’s policy has been to consistently use such citizens for spying, and letting such people into NASA operations makes no sense.

Moreover, shouldn’t NASA be hiring Americans first and foremost?

Update on what SpaceX learned about Starship’s tiles during the 10th test flight

11:27 am

Superheavy after its flight safely captured at Boca Chica
Superheavy after the October 2024 flight,
safely captured during the very first attempt

Link here. The update comes from a presentation given this week by Bill Gerstenmaier, SpaceX’s executive in charge of build and flight reliability, at the American Astronautical Society’s Glenn Space Technology Symposium in Cleveland.

Lots of new details. First, almost no tiles fell off during this flight. More significant, they found that the use of metal tiles won’t work. They tested three, and found that “The metal tiles… didn’t work so well.”

Gestenmaier also outlined how the flight provided the necessary data for sealing the gaps between the tiles better.

Gerstenmaier pointed to a patch of white near the top of Starship’s heat shield. This, he said, was caused by heat seeping between gaps in the tiles and eroding the underlying material, a thermal barrier derived from the heat shield on SpaceX’s Dragon spacecraft. Technicians also intentionally removed some tiles near Starship’s nose to test the vehicle’s response.

“It’s essentially a white material that sits on Dragon and it ablates away, and when it ablates, it creates this white residue,” Gerstenmaier said. “So, what that’s showing us is that we’re having heat essentially get into that region between the tiles, go underneath the tiles, and this ablative structure is then ablating underneath. So, we learned that we need to seal the tiles.”

They hope to do the 11th test flight in October, repeating the same suborbital configuration of previous flights, using the same version 2 of Starship. The plan will then be to follow up with a first suborbital flight of version 3 in 2026, followed quickly by orbital flights. During one of those orbital flights they will also try to do a chopstick catch of Starship. They also hope to do the first refueling tests next year.

All in all, it appears the test program is proceeding as hoped, and is about to accelerate significantly.

NASA promotes the non-discovery of life on Mars by Perseverance

11:09 am

It's all a game of Kibuki theater
It’s all a game!

In what can only be called a kabuki theater stunt, NASA today held a press conference and issued a press release promoting what is essentially the non-discovery of life on Mars by the science team operating the rover Perseverance.

Agency officials, led by acting NASA administrator Sean Duffy, proudly claimed the discovery justified the oft-stated goal of Perseverance, to find life on Mars.

“This finding by Perseverance, launched under President Trump in his first term, is the closest we have ever come to discovering life on Mars. The identification of a potential biosignature on the Red Planet is a groundbreaking discovery, and one that will advance our understanding of Mars,” said acting NASA Administrator Sean Duffy.

This is all garbage. First, Perseverance’s real objective has never been to find life on Mars. It is there to study the planet’s geology. If it should happen to detect a biosignature that would be great, but doing so has always been highly unlikely.

Second, the discovery that Duffy touts is itself quite underwhelming. The key quote from the press release that immediately precedes Duffy’s claim is very telling:

A potential biosignature is a substance or structure that might have a biological origin but requires more data or further study before a conclusion can be reached about the absence or presence of life.

Furthermore, the biosignature that Duffy touts is actually not really a biosignature. They found “a distinct pattern of minerals” that might be sometimes be related to life processes, but not always.

The combination of these minerals, which appear to have formed by electron-transfer reactions between the sediment and organic matter, is a potential fingerprint for microbial life, which would use these reactions to produce energy for growth. The minerals also can be generated abiotically, or without the presence of life. [emphasis mine]

In other words, the data is very uncertain. It certainly doesn’t merit the loud push NASA and Duffy is giving it.

I suspect this push is the result of NASA’s fundamental lie about Perseverance’s so-called search for life, a lie that can never really be fulfilled. It is also related to hiding Perseverance’s limited capabilities. For example, Curiosity has a small lab allowing scientists to analyze samples in great detail. If Curiosity came across a real biosignature, it would be able to identify it.

Perseverance lacks this ability, because in its stead it has equipment for preserving core samples for later pick-up. All it really was designed to do was to gather those core samples. It can’t really do the same kind of ground analysis as Curiosity.

Croatian startup moves up the launch date for two subscale returnable capsules

9:44 am

The Croatian startup Genesis Space Flight Laboratories (Genesis SFL) has now accelerated the development of its orbital returnable capsule for manufacturing in space, moving up the launch date for its first two subscale demonstrator capsules from 2027 to 2026.

Initially planned for 2027, the missions were moved forward after Genesis SFL announced on 9 September that it had secured earlier slots with an as-yet-undisclosed launch provider.

Speaking to European Spaceflight, Genesis SFL CEO Bence Mátyás explained that the company’s GEN-1 and GEN-2 demonstrators will likely be the smallest reentry capsules ever flown, comparable in size to picosatellites. Despite their diminutive size, the capsules will be capable of remaining in orbit for approximately six months before performing reentry procedures, a capability made possible by the use of a host satellite [essentially the service module] also under development by the company. Once on a reentry trajectory, the capsule will separate from its host satellite and deploy a mini-parachute and antenna to enable recovery following a splashdown.

If these demonstrators succeed, the company plans to scale up later GEN capsules step-by-step, eventually matching and even exceeding those of companies like Varda.

The returnable capsule industry appears at the moment to be bursting with new companies. In the U.S. we have Varda, Inversion Space, Sierra Space, and even SpaceX using Starship. In Europe — in addition to Genesis in Croatia, we have The Exploration Company in France, Atmos in Germany, PLD in Spain, and Space Cargo in Luxembourg. And I am certain there are others that I am missing.

Very clearly the investment community sees big profits in using orbital capsules to manufacture products for later sale on Earth.

Rather than streamline red tape, a UK government committee proposes it should fund its space industry directly

9:28 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

In a move that will do nothing to solve the red tape that has stymied the spaceports in Scotland as well as the launch industry in the United Kingdom, a Scottish government committee has concluded that the solution is for the UK government to become a direct investor in its space industry, increasing funding to both its spaceports and any launch companies that wish to use them.

The Scottish Affairs Committee heard from a number of experts and figures involved in the space industry. Professor Malcolm Macdonald, of Strathclyde University, said the UK had not always sustained its “first-mover” advantage in the space launch sector.

The report’s conclusion stated: “It is clear that the UK is falling behind its European counterparts in terms of public investment, leaving Scottish spaceports at a competitive disadvantage in a fast-moving global market. Without sustained backing from the Government – particularly in infrastructure – Scotland risks missing a generational opportunity to lead in space launch. To fully realise this potential, the UK Government needs to go further and faster.”

The MPs called for sustained Government investment in infrastructure.

The report also noted that despite a half-decade head start in establishing its spaceports in Scotland, the Andoya spaceport in Norway is now winning the race to become Europe’s prime spaceport.

Talk about not seeing the forest for the trees. The reason the UK’s spaceports have fallen behind is because its regulatory framework is impossible to navigate, taking years to get any approvals. But rather than fix this, this committee proposes throwing taxpayer money at the problem.

My prediction: It won’t work. Outside rocket companies will continue to move away from the UK, while any that get government investment to stay will find it difficult to get business, because it will still be impossible to get launch licenses when needed.

India’s government finalizes deal to transfer operation of its SSLV rocket to a private company

9:13 am

India’s government and its various space agencies yesterday finalized its deal with the Indian company Hindustan Aeronautics Limited (HAL) to take over the manufacture and operation of its government-designed SSLV rocket (Small Satellite Launch Vehicle) for the next decade.

Under the technology transfer contract that HAL signed with ISRO, Indian National Space Promotion and Authorisation Centre (IN-SPACe) and NewSpace India Limited (NSIL), the aviation major will absorb the technology in the first two years, which will be followed by a 10-year production phase. The agreement grants HAL a non-exclusive, non-transferable license to the SSLV technology, which includes comprehensive design, manufacturing, quality control, integration, launch operations, and post-flight analysis documentation, as well as training and support. HAL will be responsible for the mass production of SSLV to meet Indian and global demands,” the company says in a statement.

Initially the Modi government had implied the transfer would involve ownership of the rocket by the private company, so that it could market the rocket for profit. The actual deal does not do this. Instead, it gives HAL the responsibility to manufacture and operate the rocket, but it appears sales and ownership will still be under the control of India’s space agency ISRO. If this is correct, the deal accomplishes less than nothing, and in fact simply adds another player in the game, making the SSLV rocket less competitive in the international market.

Then again, the Modi government might see this deal as just a first step in the transition from a government-run space program to a competitive independent space industry. It needs to wrest control from ISRO, and this can’t be done politically in one fell swoop.

To me however this deal for HAL is a bad one. It now has the responsibility for making and launching the rocket, but none of the benefits.

South Korea military begins project to develop a methane-fueled rocket engine

8:01 am

The South Korean defense department has awarded a consortium of Korean aerospace companies a contract to develop a methane-fueled engine that can be used in reusable rockets.

According to the space industry, a consortium led by Hyundai Rotem and Korean Air was selected on the 9th as the preferred negotiator for a 35-ton methane engine technology development project overseen by the Agency for Defense Development (ADD) under the Defense Acquisition Program Administration (DAPA). A formal agreement will be signed in November, initiating full-scale research and development (R&D). The project, budgeted at approximately 49.1 billion Korean won [$35 million], will run until 2030.

It appears there has been a turf war between the military and South Korea’s newly formed space agency, KASA. Originally KASA had planned to develop this engine, but apparently the military’s proposal won out. KASA now says it will collaborate with the ADD, but the project’s budget now goes to the military.

NASA inspector general: Dragonfly mission is vastly overbudget and behind schedule

9:24 am

over Titan’s surface

According to a new NASA inspector general report issued today, NASA’s Dragonfly mission to Titan is now billions overbudget and is likely not be ready to launch in 2028.

You can download the report here [pdf]. From its executive summary:

Dragonfly was selected under a New Frontiers Announcement of Opportunity with a $850 million cost cap on Principal Investigator-Managed Mission Costs, which primarily includes development costs but excludes launch vehicle and post-launch operations costs. However, by April 2024, those costs had grown to $2.6 billion and the launch delayed by more than 2 years, from April 2026 to July 2028. The cost increase and schedule delay were largely the result of NASA directing APL to conduct four replans between June 2019 and July 2023 early in Dragonfly’s development. Justifications for these replans included the COVID-19 pandemic, supply chain issues, changes to accommodate a heavy-lift launch vehicle, projected funding challenges, and inflation.

The report now estimates the budget will eventually rise above $3 billion, cost that is eating away at NASA’s entire planetary budget, making other missions impossible. The project itself is far from ready, with multiple unfinished issues that make its present launch target of 2028 very unlikely.

China launches 11 more satellites for its Geely satellite constellation

8:09 pm

Earlier today China successfully launched 11 more satellites for its Geely satellite constellation, its Smart Dragon-3 rocket lifting off from a launch platform off the eastern coast of China.

Video of the launch can be found here (Hat tip to BtB’s stringer Jay). This was the fifth launch for this constellation, bringing the number of satellites in orbit for this planned 240 satellite constellation to 52. The constellation is designed to provide positioning and communications for trucking and other ground-based businesses.

The leaders in the 2025 launch race:

114 SpaceX
52 China
12 Rocket Lab
11 Russia

SpaceX still leads the rest of the world in successful launches, 114 to 89.

Clumps of dust in a star-forming cluster

Clumps of dust in a star-forming region
Click for original image.

Cool image time! The picture to the right, cropped and reduced to post here, was taken by the Hubble Space Telescope as part of a study of the dusty clouds inside star-forming regions. From the caption:

Stars in a star cluster shine brightly blue, with four-pointed spikes radiating from them. The centre shows a small, crowded group of stars while a larger group lies out of view on the left. The nebula is mostly thick, smoky clouds of gas, lit up in blue tones by the stars. Clumps of dust hover before and around the stars; they are mostly dark, but lit around their edges where the starlight erodes them.

This cluster sits inside the Large Magellanic Cloud, about 160,000 million light years away and the largest of the several known dwarf galaxies to orbit the Milky Way. It is the second largest such star-forming region with that dwarf galaxies, and thus is a prime research target for studying the birth of stars.

I especially like this image because of the small dust clouds that sit in the foreground, blobs of material that is slowly being ionized away by the radiation from the stars.

In reviewing the pictures downloaded today by the Mars rover Curiosity, I noticed something very intriguing in the pictures taken by rover’s two navigation cameras. One such picture is above, taken by the right navigation camera and looking west across the boxwork ridges that Curiosity has been traversing for the past two months. You can see two such ridges in the right foreground, cutting diagonally from left to right.

The overview map to the right gives the context, with the blue dot marking Curiosity’s position. The white and red dotted lines indicate its actual and planned routes respectively, with the top inset zooming in to show the recent travels more clearly. The yellow lines show the approximate area covered by the picture above.

Note the dark streak in the lower right of the picture. The bottom inset on the overview map shows this streak more closely. To my eye, it strongly resembles a slope streak, a strange geological feature unique to Mars.

If I am right, expect the rover team to focus in on this streak. The cause of slope streaks remains unknown. From orbit, the streaks look like avalanches at first glance, but they don’t change the topography, have no debris pile at their base, and sometimes even travel up and over rises as they head downhill. They can occur randomly throughout the year, can be bright or dark, can occur anywhere, and fade with time.

There are a number of theories (see here, here, and here) attempting to explain their cause, but none has been confirmed. If this is a streak, it will be the first that any scientist can see up close.

It is also very likely my guess is wrong, and this is not a streak. Stay tuned for updates.

EchoStar sells spectrum licenses to SpaceX for $17 billion while buying into Starlink

9:05 am

EchoStar today announced it has sold two of its spectrum licenses to SpaceX for $17 billion, in a deal that will also allow EchoStar’s customers to access Starlink.

EchoStar has entered into a definitive agreement with SpaceX to sell the company’s AWS-4 and H-block spectrum licenses for approximately $17 billion, consisting of up to $8.5 billion in cash and up to $8.5 billion in SpaceX stock valued as of the entry into the definitive agreement. Additionally, the definitive agreement provides for SpaceX to fund an aggregate of approximately $2 billion of cash interest payments payable on EchoStar debt through November of 2027.

In connection with the transaction, SpaceX and EchoStar will enter into a long-term commercial agreement, which will enable EchoStar’s Boost Mobile subscribers – through its cloud-native 5G core – to access SpaceX’s next generation Starlink Direct to Cell service.

Essentially, in exchange for the spectrum EchoStar is investing in SpaceX.

EchoStar also today canceled a contract it had signed in early August with the satellite company MDA to build its own 100 satellite constellation designed to provide direct-to-cellphone service, competing with Starlink and AST SpaceMobile. EchoStar will no longer build a rival constellation.

Wall Street apparently liked this deal, as EchoStar’s stock value quickly rose about 19%. It also appears the deal resolves questions the FCC had raised about EchoStar recent activities.

Two more launches today

3:35 pm

As expected, SpaceX and China completed launches today.

First SpaceX launched another 24 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its 20th flight, landing on a drone ship in the Pacitic.

Next, China placed an unspecified “group” of “remote sensing” satellites into orbit, its Long March 6A rocket lifting off from its Taiyuan spaceport in northeast China. No word on where the rocket’s lower stages crashed inside China.

The leaders in the 2025 launch race:

114 SpaceX
51 China
12 Rocket Lab
11 Russia

SpaceX still leads the rest of the world in successful launches, 114 to 88.

China yesterday completed two launches

9:03 am

China yesterday successfully completed two launches using different rockets from two different spaceports in the country’s interior.

First, its Long March 3C rocket launched a classified technology test satellite, the rocket lifting off from its Xichang spaceport in southwest China. No real information about the satellite was released, though its name, Shiyan, is part of a series of satellites that tests new designs for communications and remote sensing.

Next, the pseudo-company Galactic Energy placed three satellites into orbit, its solid-fueled Ceres-1 rocket lifting off from the Jiuquan spaeport in northwest China. Once again, little information was released about the satellites’ purpose.

With each launch, China’s state-run press also provided no information about where the lowers stages of both rockets landed inside China. This is especially of concern for the Long March 3C, which uses very toxic hypergolic fuels that can dissolve the skin.

The leaders in the 2025 launch race:

113 SpaceX
50 China
12 Rocket Lab
11 Russia

SpaceX still leads the rest of the world in successful launches, 113 to 87.

These numbers should change again by the end of today, with both SpaceX and China planning an additional launch each.

Astrobotic signs launch deal with Norway’s Andoya spaceport

9:01 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

The American lunar lander startup Astrobotic (which is now also a rocket startup) has signed a launch deal with Norway’s Andoya spaceport, where the company intends to launch its proposed reusable Xodiac rocket.

Astrobotic will perform their initial European Xodiac launch campaign operations from Andøya Space starting in 2026. Andøya Space will provide various services, including ground operations, flight preparation, and infrastructure support.

It will be wise to remain skeptical about Astrobotic’s rocket. The company owns the rights and technology of the vertical take-off-and-landing hopper developed and successfully tested by Masten Space System (which Astrobotic took over in 2022), but it also claimed in 2024 it would begin flying an upgraded suborbital version by 2025. No such flights appear on the horizon at this moment.

At the same time, developing a new rocket always involves delays. It will be quite exciting if Astrobotic succeeds in entering the launch market in the next year or so.

As for the Andoya spaceport, it continues to be in the lead among the four spaceports proposed surrounding the Norwegian Sea. Norway has made its licensing arrangement smooth and easy, the spaceport is well located, and it already has another launch contract with the German rocket startup Isar Aerospace, which attempted its first launch there earlier this year (albeit a failure). Moreover, Andoya has signed an agreement with the U.S. allowing American commercial companies to launch there, which is likely why Astrobotic made its deal.

Esrange’s location in the interior places it at a disadvantage, while red tape have badly stymied the two spaceports proposed in the United Kingdom.

A simple phone device for kids

8:40 am

A British company is selling a very simple phone device for young children that allows them to stay in contact with their parents, including GPS location, without giving them a touchscreen and any access to the web.

The Messenger, from London-based outfit Karri, is meant to help kids aged 5-13 become more independent, while giving their parents peace of mind. It’s designed entirely around voice messaging, so you can chat with your child one-on-one, or connect them with other family members in a group conversation.

This is actually the company’s second-generation Messenger with an improved design over the first from 2023. It features a dot matrix display, a speaker, and most importantly, a “slide to talk” button in the center. Slide it down to listen to a voice message you’ve just received, slide up and hold to record a reply, and short slide up to send it off.

Considering the increasing evidence that smartphones do real damage to kids during their development ages, this kind of option makes sense. So does a simple flip phone, but this device provides a simpler and more limited alternative.
