Goldstone antenna damaged and out of service

8:49 am

The Goldstone antenna in California that is a major component in NASA’s Deep Space Network (DSN) that it uses to communicate with interplanetary spacecraft was damaged recently and is presently out of service, with no known date for when or even if it will be repaired.

NASA’s Jet Propulsion Laboratory confirmed Nov. 10 that the 70-meter antenna at the Deep Space Network (DSN) site in Goldstone, California, has been offline since Sept. 16, with no timetable for its return to service. “On Sept. 16, NASA’s large 70-meter radio frequency antenna at its Goldstone Deep Space Communications Complex near Barstow, California, over-rotated, causing stress on the cabling and piping in the center of the structure,” JPL said in a statement to SpaceNews. “Hoses from the antenna’s fire suppression system also were damaged, resulting in flooding that was quickly mitigated.” [emphasis mine]

This statement suggests that as workers were changing the antenna’s orientation, it was moved too far in one direction, beyond the normal limits of that piping and cabling. The immediate question that the JPL statement avoids is this: What caused the antenna to “over-rotate”? Did something fail to stop it from going too far? Or was this an example of simple human error, whereby the person rotating the antenna failed to pay attention and allowed the antenna to exceed its limits?

Either way, the loss of this antenna not only poses a serious limitation in getting data back from the various unmanned probes at Mars, Jupiter, and elsewhere, it is also a problem for the upcoming Artemis-2 mission in the spring of ’26, which will rely on the Deep Space Network to communicate with the astronauts on Orion as it goes to and from the Moon. The network’s other two antennas in Spain and Australia can pick up the slack, but the system will have less redundancy, and more important, other missions will likely have to delay communications in order to give Artemis priority.

The edge of Mars’ north polar ice cap

11:47 am

The fringe of Mars' perennial ice cap
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on September 29, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The picture shows what the science team labels as a “fringe of perennial ice.” For this picture, north is down. The white stuff on the top half of the image is that perennial ice, while the dark material at the bottom is likely a mixture of dust and debris that is still impregnated with ice.

Mars is a very icy world. Orbital data now suggests that above 30 degrees latitude there is a lot of near surface ice, though it is often mixed in with the red planet’s ample dust, blown there for eons. This location however shows us a place where that ice is on the surface, and is generally pure.

That does not mean however this will be a good location to establish a colony.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Kazakhstan expanding its access to multiple internet satellite constellations

9:40 am

It appears the Kazakhstan government is making multiple internet satellite constellations available to its citizens in an effort to increase competition and lower costs.

Kazakhstan first engaged with Starlink in 2023, following government frustration over the slow pace of domestic telecom expansion. The project initially connected 2,000 rural schools, and by mid-2024 nearly 1,800 had access to satellite internet.

Authorities briefly considered banning satellite internet services operated from abroad late last year, citing national security concerns, but withdrew the proposal after a public backlash.

Meanwhile, competition in the country’s nascent satellite internet market is heating up. In September 2024, Kazakhstan signed an agreement with Amazon to bring its Project Kuiper satellite network to the country, setting up a future rival to Starlink. Prime Minister Olzhas Bektenov said the move would help improve affordability and service quality. Chinese firm Spacesail Kazakhstan, a subsidiary of Spacesail International, has also registered at the Astana International Financial Centre (AIFC) with $17mn in capital, positioning itself as another potential player in the mega-constellation internet sector.

When Kazakhstan opened Starlink to all its citizens in June 2025, I noted how this deal indicated the country’s move away from Russia. Its willingness now to add Kuiper and Spacesail deals accelerates that move, in numerous ways. It not only wants its citizens to have capabilities that Russia cannot control, it wants to encourage competition to lower costs for those citizens. What a concept!

Like the Ukraine, Kazakhstan is working hard to exceed Russia in technology, in order to make it much harder for its big and very power-hungry neighbor to dominate or even invade it.

China’s Zhuque-3 reusable rocket now ready for its first launch

9:26 am

According to a report in China’s state-run press today, the Zhuque-3 (ZQ-3] rocket, built by the pseudo-company Landspace, is now cleared for its first launch, though no launch date has yet been announced.

If everything goes according to schedule, the first ZQ 3 will take to the sky in the near future at the Jiuquan Satellite Launch Center in northwestern China’s Gobi Desert and will attempt to recover its first-stage booster, according to the Beijing-headquartered enterprise.

The rocket is now undergoing technical testing at the Jiuquan spaceport, which has a dedicated launch service tower for the ZQ 3 series.

Though the rocket is methane-fueled, its overall design is a copy of work already done by SpaceX, with a stainless steel first stage with nine engines designed to land vertically after launch and then reused. It is also appears in the lead among about a dozen Chinese pseudo-companies attempting to build reusable rockets.

The Chinese government has recently been pressuring its pseudo-companies to accelerate development. Right now, only three have done any static fire tests, and only one, Landspace, appears ready to launch. There have even been rumors that China might reorganize these fake companies into a government-run operation.

Avio to provide solid-fueled motors to Lockheed Martin and Raytheon

9:08 am

The Italian rocket company Avio has now signed deals with both Lockheed Martin and Raytheon to provide each with solid-fueled rocket motors for U.S. missiles, built at its planned American-based factory, expected to begin operations in 2028.

Under the arrangement with Lockheed Martin, “Lockheed Martin will have preferred access to a portion of the Avio USA plant production capacity to meet future demand for its products,” according to Avio. Tim Cahill, president of Lockheed Martin Missiles and Fire Control, said the collaboration “positions us to increase production of essential capabilities and deliver them to our customers faster as global demand grows.”

Raytheon will receive similar preferred access to production capacity under a comparable agreement. The deal follows a July 2024 contract between the companies for preliminary engineering work on a tactical rocket motor for Raytheon’s Standard missile program for the U.S. Navy. Bob Butz, vice president of operations, supply chain and quality at Raytheon, said the agreement “will help establish an additional supplier of solid rocket motors within the U.S.”

In both cases, these solid-fueled motors will be used in U.S. missiles.

Since Avio regained control of its rockets and engines from Arianespace — the government-controlled commercial arm of the European Space Agency (ESA) – it has been moving very fast to obtain customers worldwide. Under ESA control, Arianespace was focused on doing business in Europe, so establishing a factory in the U.S. to garner U.S. business was never even considered. Avio is not hindered by such restrictions, and it is therefore looking for profits wherever it can find them. It has committed almost a half billion dollars to build this U.S. factory, and has begun signing up international satellite companies for its Vega-C rocket. It is also begun work on a Grasshopper-type test vehicle, with plans to incorporate this concept into Vega-C, making its first stage reusable.

The above deal also indicates that Avio is grabbing market share from the established American makers of solid fueled rockets, especially Northrop Grumman. Apparently those American companies aren’t providing manufacturing capacity required by the Pentagon.

New company formed to run proposed North Sea offshore launch platform

8:50 am

Launch platforms proposed for North Sea
Launch platforms proposed for North Sea

The German company OHB has now formed a new subsidiary, The European Spaceport Company, to consolidate its various spaceport projects, its proposed North Sea offshore launch platform as well as the launchpads it is building at French Guiana.

According to an 11 November OHB press release, the initial goals of the new European Spaceport Company, which will be based in Bremen, are the “realisation of a European offshore spaceport and the expansion of launch capacities at the Kourou spaceport in French Guiana to include a launch complex that can be used for various rocket types.”

The home port for the offshore spaceport, dubbed the Offshore Spaceport Alliance, will be in Bremen, as shown by the map to the right. The launch facilities the company is building in French Guiana are for the German rocket startup Rocket Factory Augsburg as well as Arianespace’s Ariane-6 rocket.

The North Sea launch platform appears to be an attempt to give the three German rocket startups, Rocket Factory, Isar Aerospace, and Hyimpulse, a German-based launchpad close to Europe, rather than have to rely on the new spaceports in the United Kingdom, Norway, and Sweden that surround the Norwegian Sea to the north.

First launch of Rocket Lab’s Neutron rocket delayed until 2026

8:34 am

Artist's rendering of the Neutron first stage deploying its second stage

to deploy the payload with the second stage engine.

Despite a concerted effort in the past year to achieve the first launch of its new reusable larger Neutron rocket before the end of 2025, Rocket Lab this week revealed that the company is now targeting a 2026 launch instead.

Sir Peter Beck, the CEO of Rocket Lab, announced the shift in plans during the third quarter earnings call with investors on Nov. 10. He said that the company’s goal is to get the rocket out to Launch Complex 3 at the Virginia Spaceport Authority’s (VSA) Mid-Atlantic Regional Spaceport (MARS) within the first quarter of 2026 “with first launch thereafter.”

“As always, this is a rocket program that’s been completed at a pace and a cost that nobody has achieved before and the financial and long-term impacts are insignificant to take a little bit more time to get it right,” Beck told investors on the call.

During the call officials also made clear that there would be no attempt to recover the first stage on that first flight, as the landing barge won’t be ready by then. It hopes a landing attempt will occur on the second flight.

Finally, officials revealed that the company has spent a bit more to develop Neutron then the originally planned cost of between $250 to $300 million. Right now it expects to spend about $360 million by the end of 2025.

This delay or the increased cost are relatively inconsequential when looked at in context. Rocket Lab had only started this project in 2021. To create a new rocket in less than five years for only about a quarter of a billion dollars is quite unprecedented.

SpaceX launches 29 more Starlink satellites

8:47 pm

Note: My original post mistated the time of launch. Below is a corrected text:

SpaceX tonight at 10:21 pm (Eastern) successfully launched another 29 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its third flight, landing on a drone ship in the Atlantic.

I specify the launch time because it occurred just outside the FAA’s so-called curfew banning all launches from 6 am to 10 pm local time, due to the government shutdown and a shortage of air traffic controllers to coordinate aviation and rocket launches. Though the Senate today voted to end the shutdown, that shutdown has not yet ended, and won’t until the House passes the Senate budget version and Trump signs it.

Thus, it appears Blue Origin has negotiated an exemption for its now planned launch of New Glenn on November 12, 2025 in the afternoon.

The leaders in the 2025 launch race:

147 SpaceX (a new record)
70 China
14 Rocket Lab
13 Russia

SpaceX now leads the rest of the world in successful launches, 147 to 115.

Note that I had made an error in entering my numbers earlier this week in regards to China, and have now corrected the mistake, thus revising the numbers in the last few launch reports.

Curiosity looks downhill at past travels

9:31 am

Curiosity looks downhill
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on November 6, 2025 by the left navigation camera on the Mars rover Curiosity.

The picture looks north across Gale Crater, its distant rim about 20-30 miles away barely visible in the dusty atmosphere. In the foreground can be seen Curiosity’s recent tracks, showing how the science team had it travel back and forth several times, probably to check out several different interesting nearby ground features, as well as see how the ground changed by that travel. The rover has been traveling in an area called boxwork, a series of small intercutting ridges and hollows. Several of those ridges can be seen just beyond the tracks.

The red dotted line indicates my rough estimate as to the rover’s route uphill to get to this point, traveling up and to the left and following ridges just out of view.

Two launches from China, one of which failed

8:32 am

China today attempted two different launches from two different launch sites, with one launch succeeding and a second failing.

First, China placed the thirteeenth set of Guowang internet satellites into orbit, its Long March 12 rocket lifting off from the Wenchang coastal spaceport. China’s state-run press did not reveal the number of satellites, though based on past launches of this constellation using this rocket the count was likely nine, which means this constellation now has about 105 satellites in orbit, out of a planned 13,000.

The rocket’s flight plan had its lower stages coming down near the Philippines, which caused that government to warn its citizens to avoid the drop zones, something it appears it has to do now for practically every launch from Wenchang.

Next, a launch of the Chinese pseudo-company’s Ceres-1 solid-fueled rocket failed during a launch from the Jiuquan spaceport in northwest China. China’s state-run pressed released no details about the failure, such as when it occurred or if the failed rocket crashed inside China.

The leaders in the 2025 launch race:

146 SpaceX
70 China (a new record)
14 Rocket Lab
13 Russia

SpaceX still leads the rest of the world in successful launches, 146 to 115.

Isaacman shows up as surprise speaker at Turning Point USA event in Alabama

9:57 am

In what could very well explain why Donald Trump changed his mind about Jared Isaacman’s nomination for NASA administration, Isaacman showed up unexpectedly at a Turning Point USA event at Auburn University in Alabama this past week, where he described how the murder of Charlie Kirk had profoundly changed his outlook on life.

[O]n a very personal note, I didn’t grow up very religious at all — my mother’s family, we celebrate Christmas. My father’s family, we celebrated Hanukkah. But I can tell you, having gone to space twice and looking back on our planet, looking at the stars around us, it is very hard not to be spiritual.

But it was only recently, in the last couple weeks that I was inspired for the first time in a very long time to pick up the Bible, and I’ll tell you why.

It’s because of Charlie, and it’s for Charlie, and there’s millions others just like me. Thank you.”

One of the theories as to why Trump withdrew Isaacman’s nomination in May was because of Isaacman’s past political and financial support for numerous Democratic Party candidates, along with his apparent support for DEI at his companies. It was speculated that once Trump learned of these associations during the confirmation process he decided Isaacman was not trustworthy and dumped him.

I wonder now if Isaacman changed Trump’s mind when they met several times in the past few weeks by talking about Kirk’s assassination and how it had changed Isaacman. I can easily see how that would have influenced Trump.

This is also another case of the Democrats and their most radical and public cohort doing a good job of alienating another former Democrat, simply by advocating and committing violence against those who disagree. They did it to Trump and Elon Musk, both former Democrats, and apparently they have done it to Isaacman as well.

Three launches since yesterday, with a fourth upcoming today [scrubbed]

9:19 am

The beat goes on: Since yesterday there were three launches globally, two by China and one by SpaceX, with a fourth launch scheduled by Blue Origin only a few hours hence. UPDATE: Blue Origin launch scrubbed due to weather].

First China’s solid-fueled Long March 11 rocket placed three classified military test satellites into orbit, lifting off from an ocean platform off China’s northeastern coast.

Next, China’s solid-fueled Kinetica-1 (Lijian-1) rocket placed two “technical satellites” into orbit, lifting off from the “commercial” launchpad at the Jiuquan spaceport in the country’s northwest. As is normal, China’s press provided no information about the satellites, nor where Kinetica-1’s lower stages crashed inside China. The rocket itself is supposedly commercial, but it is built by a government agency, the Chinese Academy of Sciences.

Finally, in the early morning hours today SpaceX placed 29 more Starlink satellites into orbit, its Falcon 9 rocket lifting off from the Kennedy Space Center in Florida.

The first stage (B1069) completed its 28th flight, landing on a drone ship in the Atlantic. With this launch this booster tied the space shuttle Columbia for the number of reuses by a launch vehicle. As the rankings for the most reused launch vehicles below show, SpaceX now has four boosters close to becoming the most reused rockets ever.

39 Discovery space shuttle
33 Atlantis space shuttle
31 Falcon 9 booster B1067
29 Falcon 9 booster B1071
29 Falcon 9 booster B1063
28 Falcon 9 booster B1069
28 Columbia space shuttle

Sources here and here.

The leaders in the 2025 launch race:

146 SpaceX (a new record)
69 China (a new record)
14 Rocket Lab
13 Russia

SpaceX now leads the rest of the world in successful launches, 146 to 114.

Blue Origin hopes to launch two NASA smallsat Mars orbiters later today from Cape Canaveral, using its New Glenn rocket. That launch is scheduled for 2:35 pm (Eastern). The company will once again attempt to land the first stage on a platform in the Atlantic. I have embedded the live stream below.

UPDATE: Launch scrubbed due to weather. The negotiations with the FAA (see below) now take on greater importance.

This will be the second launch of New Glenn, eleven months after its maiden flight in January. As has been the company’s culture for the past decade, it has moved very slowly from that first launch to this second. This pace however must accelerate soon, as Blue Origin has a 27-launch contract with Amazon to launch part of its Kuiper satellites. Amazon only has 154 satellites in orbit, and needs to get about 1,600 in place by July 2016 to meet the requirements of its FCC license. It also has launch contracts with ULA (46 launches, three of which have been completed) and ArianeGroup’s Ariane-6 (18 launches), but neither can on their own launch enough to do the job.

One last note: For this launch, Blue Origin is trying to arrange an exemption from the FAA’s curfew on day launches that begins tomorrow, in case some issue causes a scrub today. No word as yet on whether the FAA will agree.

Crazy layers inside a Martian crater

2:49 pm

Crazy layers 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 September 30, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists label this image with the term “layers”, but to my eye this is kind of an understatement. The geology in the top half of this picture is more than simply layers, it is an example of that unique Martian geological feature dubbed “brain terrain”, but on steroids.

No one yet knows what causes brain terrain, though scientists think it is related to the sublimation of near surface ice. Normally the tubelike formations are much smaller, only ten to thirty feet long, not hundreds of feet as we see here.

In this case the location of these features makes their formation even more puzzling, as there is no near surface ice found here.

Profits for Luxembourg satellite company SES drop due to U.S. budget cuts and shutdown

10:10 am

According to its third quarter report, the profits of Luxembourg satellite company SES were impacted negatively because of the budget cuts of the Trump administration, and were then further impacted because of the extended government shutdown.

Revenue over the first nine months of this year rose 20% to €1.75 billion while losses mounted to €55 million so far in 2025. Part of the problem was the Trump administration reassessment of spending that had been decided last year, including the delay of contract renewals and decisions on new awards, Chief Executive Officer Adel Al-Saleh said. Large contracts have also been delayed by the longest congressional budget standoff in US history, now in its sixth week, he said. “We’re experiencing timing delays in some contract awards due to the continuing resolution and subsequent government shutdown,” Al-Saleh said on a conference call with stock analysts.

The company remains in the black, and it expects to make up these losses from other customers. It is also in the process of completing its purchase of the satellite company Intelsat, which has also impacted its profits.

The article notes one interesting aspect of this Luxembourg company, that reflects the unique approach to tax dollars by that nation’s government: “Luxembourg taxpayers own one-sixth of SES shares, but wield a third of the voting power after underwriting its creation four decades ago.” The government doesn’t simply spend its tax revenue, like most governments. It treats that revenue as investment capital, and uses it to make money for the benefit of its citizens.

If only more governments would take this approach!

Webb tracks volcanic eruptions on Io

9:59 am

Different Webb infrared detections of Io over time
Click for original image.

Using the Webb Space Telescope, scientists have tracked two different volcanic eruptions on Io that too place from 2022 to 2023, detecting sulfur monoxide both from those eruptions as well as sulfur from the magnetic plasma torus produced as the planet travels through Jupiter’s strong magnetic field. From the paper’s abstract:

Volcanic thermal emission was detected from Loki Patera and Kanehekili Fluctus [two volcanic vents]. The main changes in the shape of the thermal emission spectra since [Webb] observed Io in November 2022 were consistent with the continued cooling of emplaced lava flows in the Kanehekili Fluctus region, and the crust that had formed on the surface of the lava lake in Loki Patera. Images of Io in the SO 1.707 μm emission band [sulfur monoxide] show a concentration above Kanehekili Fluctus and in two regions in the northern hemisphere. The emissions are sourced from SO molecules ejected from volcanic vents. We further detected, for the first time, sulfur line emissions at 1.08 and 1.13 μm. These emissions are distributed homogeneously across a band in Io’s northern hemisphere. They are mainly produced through excitation by electrons from the plasma torus, penetrating Io’s atmosphere.

The top image to the right shows the heat signature above the two volcanoes, one to the southwest and the second to the northeast. The middle image shows the sulfur monoxide emissions detected by Webb above those volcanoes from their on-going eruptions. The bottom image shows the more diffuse sulfur emissions, mostly in the northern hemisphere, believed produce by interactions with the plasma torus.

This research also relied on data obtained by both the Keck telescopes in Hawaii and the Hubble Space Telescope.

There are of course uncertainties with these results. For example, the conclusion that the more diffuse sulfur is produced by interactions with the plasma torus is not as certain. First, those sulfur emissions still appear closely linked to the volcanoes, which suggests this still could be a source.

Second, the observations also cover only two data points in time, in 2022 and 2023. To get a more precise map of the activity on Io we really need an orbiter there observing the planet on a continuous basis, something that is at this time impossible, not only because no mission is planned but because the hostile radiation environment this close to Jupiter makes the engineering quite challenging. It is this reason why Europa Clipper is not going into orbit around Europa when it arrives there in 2031. Better to orbit Jupiter and only periodically dip into that harsh radiation environment.

U.S. budget cuts shifts Blacksky’s satellite imaging business to international customers

9:24 am

Because of budget cuts by the Trump administration, the revenues of the satellite imaging company Blacksky fell in the third quarter of 2025, but the company expects to make up that loss with new income from international customers.

The administration’s fiscal 2026 budget proposal includes a one-third reduction to the National Reconnaissance Office’s commercial imagery procurement, a move that has rippled through companies like BlackSky that rely heavily on government intelligence contracts. The cuts specifically affect the Electro-Optical Commercial Layer (EOCL) program — an NRO initiative to buy satellite imagery from commercial providers.

BlackSky reported $19.6 million in third-quarter revenue, missing analyst expectations and down from the previous quarter. Chief Executive Brian O’Toole told analysts the reduction stemmed from adjustments to the company’s EOCL contract “to reflect the potential baseline budget submitted by the administration.”

Sound terrible, eh? Not so fast.

Despite the domestic headwinds, BlackSky is seeing a sharp uptick in overseas business. The company said international sales now account for about half of total revenue, up from 40% a year ago. O’Toole said foreign demand is “outpacing our U.S. government business” and that the company expects international sales to exceed U.S. sales for the first time in 2026.

Blacksky is of course blocked from selling its high resolution reconnaissance imagery to hostile powers, but there are plenty of American allies out there who want this data.

The situation is simple. When American companies are given the freedom to produce, they will create products of value. And the sky won’t fall if the federal government can no longer be their main customer.

Echostar sells more of its licensed spectrum to SpaceX

9:05 am

Echostar announced this week that it has sold additional spectrum that had been licensed to it by the FCC to SpaceX, getting in return about $2.6 billion in SpaceX stock.

EchoStar has entered into an amended definitive agreement with SpaceX to sell the company’s unpaired AWS-3 licenses for approximately $2.6 billion in SpaceX stock valued as of September 2025. This transaction builds on the agreement the companies entered into in September. EchoStar’s unpaired AWS-3 licenses are nationwide and are part of 3GPP Band 70n (1695-1710 MHz uplink). “This transaction with SpaceX, in addition to our previously announced spectrum transactions and commercial agreements, will strengthen EchoStar’s ability to develop new business opportunities and growth in value for our shareholders,” said Hamid Akhavan, CEO, EchoStar Capital. “The combination of AWS-3 uplink, AWS-4 and H-block spectrum from EchoStar with the rocket launch and satellite manufacturing capabilities from SpaceX accelerates the realization of powerful and economical direct-to-cell service offerings for consumers and enterprises worldwide, including our Boost Mobile customers.”

In other words, Echostar was not making any money from this spectrum on its own. By partnering with SpaceX it can do so, because SpaceX has the satellites and rockets capable of making it happen, and a cost that is affordable.

Nor should the companies have much problem getting FCC approval. Echostar had previously been accused of under-utilizing its licensed spectrum. This deal with SpaceX helps solve that issue.

In other Starlink news, SpaceX has begun rolling out Starlink service in India, while also striking a deal with British Airlines to use Starlink on its airplanes.

FAA issues a launch curfew due to the shutdown

10:31 pm

The Federal Aviation Administration (FAA) today issued a launch curfew that will ban all launches and re-entries from 6:00 am to 10:00 pm local time.

Accordingly, with respect to commercial space launches and reentries, under the authority provided to the FAA Administrator by 49 U.S.C. §§ 40103, 40113, and 46105(c), and authority delegated to the FAA Administrator under 51 U.S.C. § 50909(a), it is hereby ordered that, beginning at 6:00 a.m. EST on November 10, 2025, and until this Order is cancelled, Commercial space launches and reentries will only be permitted between 10:00 p.m. and 6:00 a.m. local time.

It appears the curfew has been imposed because of a shortage of air traffic controllers due to the government shutdown. Each launch needs to be coordinated with air traffic control, and it appears the FAA won’t have the people it needs to do this during the day. This is part of the overall 10% reduction in flights at forty of the busiest airports nationwide imposed at the same time, also due to the shutdown.

This order is going to probably impact planned launches by SpaceX, Rocket Lab, and others, with SpaceX likely affected the most.

Note: I got the curfew times backwards initially, and was corrected by my readers. Post is now correct.

One launch today by SpaceX, while ULA scrubs for the second time in two days

7:46 pm

SpaceX today successfully launched another 28 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.

The first stage completed its 8th flight, landing on a drone ship in the Atlantic.

ULA for the second day in a row was forced to scrub a launch of a Viasat communications satellite due to “a reoccurrence of the issue with the Atlas V booster liquid oxygen tank vent valve.” No new launch data has as yet been announced.

The contrast between these two rocket companies here is truly striking. In the past two days SpaceX’s reusable Falcon 9 has launched twice, like clockwork, while ULA can’t get off the ground because of a valve issue, the kind of niggling problem that routinely scrubs its launches. It is thus rare that ULA launches on time, on schedule, as planned.

SpaceX’s launch however sets a new record for successfully launches in a single year by the entire world, 257, breaking the record set last year. These numbers are two to five times what the global launch industry managed annually for most of the space age, and signal the renaissance in rocketry brought on by Elon Musk and SpaceX. Nor I think have we reached peak numbers. Not even close.

The leaders in the 2025 launch race:

145 SpaceX (a new record)
67 China
14 Rocket Lab
13 Russia

SpaceX now leads the rest of the world in successful launches, 145 to 112.

November 6, 2025 Quick space links

3:11 pm

Courtesy of BtB’s stringer Jay. This post is also an open thread. I welcome my readers to post any comments or additional links relating to any space issues, even if unrelated to the links below.

  • Firefly acquires the national security firm SciTec
    The company’s recent acquisitions have all been aimed at diversifying its capabilities in the direction of military contracts. Nor has Firefly been alone in this. It appears the space industry now sees defense as a future big profit center.

Judge approves plea deal related to Boeing’s malfeasance that caused two 737-Max crashes killing 346

3:03 pm

After further hearings during this past month, a judge ruled today to accept the plea deal worked out between Boeing and the Justice Department that allows the companyto avoid a criminal prosecution for its malfeasance and fraud that led to two 737-Max airplane crashes that killed a total of 346 people, thus dismissing the pending criminal charges.

A criminal conspiracy case was held against Boeing following the two fatal crashes of its 737 MAX 8 aircraft. The Department of Justice had initially accused Boeing of deceiving the federal regulators in relation to flight control system issues. Following the dismissal, Boeing has agreed that it would pay and or invest up to $1.1 billion in compensation to victims’ families, alongside other fines.

This dismissal comes almost a year after Boeing had reached an agreement with the DOJ, under which it would see the American plane manufacturer plead guilty and serve a term of probation. In a report by CNBC, the dismissal order acknowledged the victims’ families, many of whom opposed the dismissal, that the agreement could fail to secure the necessary accountability to ensure the safety of the flying public, and that the dismissal did not acknowledge that the manufacturer needed to be subject to independent monitoring.

It should be noted that Boeing has not only admitted to its corrupt behavior, it has already thumbed its nose at the Justice Department. As I noted in March,

In 2021 Boeing admitted to these charges as part of a plea deal with Justice, whereby prosecution would be deferred for three years if Boeing took certain actions to clean up its act. When that deal expired in 2024, Justice determined that Boeing had failed to live up to its agreement. Rather than go to criminal trial however government lawyers instead attempted twice to settle the case by having Boeing pay a big fine, first $243 million and then $455 million. In both cases the deals fell through when lawyers for the victims’ families objected.

The families still object, for the very rational reasons listed above. Boeing remains a very untrustworthy company, with a corporate culture that does not appear to require high standards, or even low standards, while allowing corruption and fraud to run rampant. This deal in many ways lets it off the hook.

At the same time, the deal is clearly an effort by Justice to give Boeing another opportunity to reform itself. We shall see if it works. Skepticism is certainly called for.
