SpaceX launches 21 more Starlink satellites

9:09 pm

SpaceX tonight successfully launched another 21 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg in California.

The first stage completed its tenth flight, landing on a drone ship in the Pacific.

The leaders in the 2024 launch race:

94 SpaceX
42 China
11 Russia
11 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 110 to 64, while SpaceX by itself now leads the entire world, including American companies, 94 to 80.

The United States has now tied its record for launches in a single year, 110, set only last year. It has done so however in less than three-quarters of a year, suggesting that the new record will be significantly higher. This new record mostly reflects the pace that SpaceX and Rocket Lab are setting, with most of the heavy lifting by SpaceX.

If things go as expected, expect 2025 to smash this record as well, because all signs suggest that both ULA and Blue Origin will begin launching regularly in order to meet their various contracts, joining SpaceX, Rocket Lab, and several other rocket startups.

FAA administrator claims SpaceX wasn’t following regulations; SpaceX says that’s false

4:08 pm

FAA administrator Mike Whitaker today said this to SpaceX:
FAA administrator Mike Whitaker today to SpaceX:
“Nice company you have there. Shame if something
happened to it.”

In a hearing today before the House transportation committee, the FAA administrator Mike Whitaker claimed repeatedly that the red tape his agency has imposed on SpaceX, as well as the fines it recently imposed on the company, were due to safety concerns as well as SpaceX not following the regulations and even launching without a license.

Mike Whitaker, the administrator of the FAA, told lawmakers on the House Transportation Committee that his decision to delay SpaceX’s launch for a few months is grounded in safety, and defended the $633,000 fine his agency has proposed against SpaceX as the “only tool” the FAA has to ensure that Musk’s company follows the rules.

… [Kevin Kiley (R-California)] argued those reviews don’t have anything to do with safety, prompting Whitaker to shoot back: “I think the sonic boom analysis [related to returning Superheavy back to Boca Chica] is a safety related incident. I think the two month delay is necessary to comply with the launch requirements, and I think that’s an important part of safety culture.”

When Kiley asked what can be done to move the launch up, Whitaker said, “complying with regulations would be the best path.”

SpaceX immediately responded with a detailed letter, published on X, stating in summary as follows:

FAA Administrator Whitaker made several incorrect statements today regarding SpaceX. In fact, every statement he made was incorrect.

The letter then detailed very carefully the falseness of each of Whitaker’s claims. You can read images of the letter here and here. The company noted:

It is deeply concerning that the administrator does not appear to have accurate information immediately available to him with respect to SpaceX licensing matters.

Based on SpaceX’s detailed response, it appears its lawyers are extremely confident it has a very good legal position, and will win in court. Moreover, the politics strongly argue in favor of fighting now. Though such a fight might delay further Superheavy/Starship test launches in the near term, in the long run a victory has a good chance of cleaning up the red tape for good, so that future work will proceed without this harassment.

Whitaker’s testimony also suggests strongly that he — a political appointee by the Biden administration –is likely the source of many of the recent delays and increased red tape that SpaceX has been forced to endure. He clearly thinks he knows better than SpaceX on these technical areas, even though his education and work history has never had anything to do with building rockets.

Blue Origin completes first static fire test of New Glenn upper stage

9:23 am

Blue Origin yesterday successfully conducted a 15 second static fire test of the upper stage of its orbital New Glenn rocket.

The hotfire lasted 15 seconds and marked the first time we operated the vehicle as an integrated system. The purpose of the hotfire test was to validate interactions between the subsystems on the second stage, its two BE-3U engines, and the ground control systems.

Additionally, we demonstrated its three key systems, including: the tank pressurization control system, which uses helium to pressurize the liquid hydrogen and liquid oxygen tanks during flight; the thrust vector control system, which gimbals the engines and steers the rocket during flight; and validated the start-up and shut-down sequences for the BE-3U systems, which can be restarted up to three times during a mission.

In addition to testing our flight hardware, this hotfire test was also an opportunity for the launch operations team to practice launch day procedures on console and verify timing for a number of critical operations.

An actual launch date has not been announced. Previously New Glenn was to carry two Mars orbiters for NASA and launch by October 21, 2024 at the latest. Because of doubts the company could meet that data, NASA pulled the satellites from the rocket.

Prior to launch the company still has to do a full static fire test of the rocket’s first stage. Though company officials have said this would happen “very soon,” no date has been announced for the test.

Isar begins static fire tests of its Spectrum rocket

9:44 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

Isar Aerospace, one of three German rocket startups vying to the be first to complete an orbital launch, has now revealed that it has begun static fire tests of its Spectrum rocket at its launch facility at the Andoya spaceport in Norway.

In response to questioning from European Spaceflight, Isar confirmed that all components of the Spectrum rocket that will be utilized for its inaugural flight had arrived in Andøya and that testing of the first and second stages had begun.

“All components of our launch vehicle Spectrum have arrived in Andøya and the final preparations for the first test flight of Spectrum are in full swing,” an Isar Aerospace spokesperson said. “We are currently performing hot fire tests of the first and second stages. These tests will determine whether the systems meet all the necessary requirements for the first test flight.”

The company has a 20-year lease at Andoya, and though it has not announced a launch date, these ground tests suggest that launch could occur quite soon. If so, Isar will have beaten Rocket Factory Augsburg and Hyimpulse to space. Rocket Factory had apparently been in the lead until a fire during a full static fire test of its RFA-1 rocket’s first stage in August destroyed the rocket.

This race is also between the spaceports surrounding the Norwegian Sea. Rocket Factory is launching from Saxavord in the Shetland Islands, a spaceport that has been under development the longest, since before 2020, and has been plagued with the red tape problems that appear systemic in the United Kingdom. Andoya however is a latecomer in this race. Though it has been used for suborbital tests for decades, it only started its effort to become a commercial spaceport for orbital flights in November 2023, less than eleven months ago.

SpaceX conducting salvage operations to recover a Superheavy booster in the Gulf of Mexico

9:19 am

SpaceX has apparently conducted salvage operations in the Gulf of Mexico to recover the Superheavy booster that had successfully completed a soft vertical splashdown during the fourth Starship/Superheavy test flight on June 6, 2024.

Confirmation of the recovery project came from a group of young, independent filmmakers who caught wind of the operation and chartered a boat for the 15-mile trip to the Ridgewind to see for themselves what was going on.

…After a two-and-a-half-hour cruise they were about a half mile from the Ridgewind when a drone buzzed toward them. It hovered for a moment before a voice announced through a loudspeaker: “There is a one mile exclusion zone in this area, please depart one mile away from vessel.”

The filmmakers retreated as requested, but then remained there for awhile, observing operations from a distance. They later contacted SpaceX.

The Interstellar Gateway crew reached out to SpaceX, which Leal said quickly confirmed it had contracted with Hornbeck to recover the giant booster. It asked the filmmakers to refrain from announcing the find until after the Ridgewind completed its work and began steaming to port. That happened Sunday.

The filmmakers are one of the number of independent live stream groups that record launches, and made it clear it announcing the salvage work that they respected SpaceX’s request because they knew it was entirely reasonable — to avoid safety problems that could be caused by others boating over — and that they had no desire to hinder SpaceX’s effort.

The article, from a mainstream Democratic Party propaganda source, however tried to slam SpaceX for its “secretive nature,” something that is so untrue only a Democrat shill could write it with a straight face. It also spent a lot of time criticizing the company for creating that one-mile safety exclusion zone around its salvage operations, questioning SpaceX’s “authority” to do so.

China and Rocket Lab complete launches

3:11 pm

Yesterday there were two more launches. First China’s Long March 2D rocket in the very early morning hours lifted off from its Taiyuan spaceport in northern China, placing six satellites in orbit.

The satellites are part of a constellation for doing high resolution Earth observations. No word on where the rocket’s lower stages, using very toxic hypergolic fuel, crashed inside China.

Next Rocket Lab successfully launched five satellites for the French satellite company Kinéis. This was the second of five planned launches by Rocket Lab to put the entire 25 satellite internet-of-things constellation into orbit. It was also the second attempt to launch, with the first experiencing a launch abort at T-0 seconds due to a ground-system issue.

The launch pace is beginning to heat up. There were four launches yesterday, two from China, one from SpaceX and one from Rocket Lab. The leaders in the 2024 launch race:

93 SpaceX
41 China
11 Russia
11 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 109 to 63, while SpaceX by itself now leads the entire world, including American companies, 93 to 79.

Boeing replaces the head of its defense/space/security division

4:24 pm

Ted Colbert
Ted Colbert

Boeing today announced that the head of its defense/space/security division, Ted Colbert, has been removed, effective immediately.

New Boeing CEO Kelly Ortberg in his first significant move since taking over in August, said Ted Colbert would be leaving and Steve Parker, the unit’s chief operating officer, would assume Colbert’s responsibilities until a replacement is named at a later date.

One project that Colbert was in charge of was Starliner, a program that has cost the company at least $1.6 billion in overruns because of numerous faulty engineering problems.

Colbert might not be to blame for the endless problems at Starliner, but the fish stinks from the head. He also might be very qualified, but sadly, as his picture shows, he is a minority, and since Boeing went all in on DEI racist hiring quotas a few years ago, which makes the skin color and gender of an applicant a major qualification in hiring, one can’t help wondering if he was a DEI (Didn’t Earn It) hire. At Boeing that policy created a goal to increase black staffing by 20%. Its full report [pdf] makes it very clear it no longer made talent, experience, or skill the primary qualification for getting hired, but skin color and sex took precedence.

As I said, one cannot help wondering if Colbert was hired not because of his great management and engineering knowledge, but because he happened to born with a dark skin color. If so, that might help explain the failures in this paricular division.

A review of Firefly’s new launch facilities in both the U.S. and Sweden

10:19 am

Link here. The company already has leases for launchpads at both Vandenberg and Cape Canaveral, though only the Vandenberg pad is presently operational. It now building new pads in Viriginia at Wallops Island and in Sweden at the commercial Esrange spaceport.

Regarding the purpose of offering a launch site in Europe, Firefly stated to NSF, “The launch cadence will largely be driven by customer demand. With the inaugural Alpha launch from Esrange as early as 2026, the new complex can support commercial customers in the broader European market and enable tactically responsive space missions to further advance national security for NATO countries.”

The company has already completed five launches from Vandenberg, with a sixth upcoming.

SpaceX finds a way to extend the launch window for Europa Clipper

10:03 am

The launch window for SpaceX’s launch of NASA’s Europa Clipper to Jupiter has now been extended a full week because the company has revised the launch process and made hardware changes.

The new launch window runs from October 10th to November 6th.

Usually the two side boosters come back to land at Cape Canaveral Space Force Station so they can be reused and sometimes the core booster is recovered at sea, but not this time. All their fuel will be used to get Europa Clipper on its way to Jupiter. Piloto said SpaceX “made some hardware modifications that enable the launch vehicle to utilize all the fuel in the boosters,” but couldn’t go into detail about what they are because the information is proprietary.

[The NASA official] added that SpaceX has gained experience in flying this configuration — it’s the 11th Falcon Heavy launch — and the company has “come up with a strategy to optimize throttling of the launch vehicle to get more performance out of it.”

NASA and SpaceX have also decided to use NASA’s orbiting communications constellation during the launch instead of ground stations, which increases their flexibility and margins.

I wonder if the FAA has approved these changes. Or even if anyone there even understands them.

SpaceX and Elon Musk blast the FAA’s red tape again

9:54 am

Are Americans finally waking up and emulating their country's founders?

Fight! Fight! Fight! Yesterday both SpaceX and Elon Musk renewed their attack on the FAA’s apparent arbitrary harassment of the company, both by slowing down development of Starship/Superheavy as well as imposing fines and delays on the company for petty issues relating to Falcon 9 launches.

First, Elon Musk sent out a tweet on X, highlighting a successful static fire launchpad engine test of the Starship prototype the company plans to fly on the sixth Starship/Superheavy orbital flight. As he noted with apparent disgust, “Flight 5 is built and ready to fly. Flight 6 will be ready to fly before Flight 5 even gets approved by FAA!”

Second, and with more force, the company released a public letter that it has sent to the leading Republican and Democratic representatives of the House and Senate committees that have direct authority over space activities, outlining its issues with the FAA’s behavior. The letter details at length the irrational and inexplicable slowdown in FAA approvals that caused two launches last summer to occur in a confused manner, with SpaceX clearly given the impression by the FAA that it could go ahead which the FAA now denies. In one case the FAA claims SpaceX removed without its permission a poll of mission control during its countdown procedure. SpaceX in its letter noted bluntly that the regulations do not require that poll, and that the company already requires two other polls during the count.

In another case involving SpaceX’s plan to change to a new mission control center, the company submitted its request in June, and after two months the FAA finally approved the control center’s use for one launch, but had still not approved it for a second. The first launch went off, so SpaceX thus rightly assumed it could use the control center for the second. Yet the FAA is now trying to fine SpaceX for that second launch.

The third case of FAA misconduct appears to be the most egregious. » Read more

FCC commissioner slams FCC for its partisan hostility to SpaceX

10:27 am

The FCC proves its partisan hostility to SpaceX
The FCC proves its partisan hostility to SpaceX

Even as the FAA has increasingly appeared to be harassing SpaceX with red tape, FCC commissioner Brendan Carr this week slammed his own agency for what appears to be clearly partisan hostility to SpaceX in its recent decisions and public statements.

Carr noted how only last year the FCC had canceled an almost $900 million grant that it had previously awarded to SpaceX for providing rural communities internet access. When it did so, the FCC claimed that the company had failed to “demonstrate that it could deliver the promised service.”

That claim of course was absurd on its face, considering that Starlink was the only available commercial system that was actually doing this, directly to individual rural customers.

Carr noted however that this absurd FCC decision was made even more ridiculous this week by the FCC’s chairperson, Jessica Rosenworcel, who accused SpaceX of being a “monopoly” because of its success in launching Starlink satellites and providing this service ahead of everyone else.

Sierra Space successfully tests equipment for extracting oxygen from the lunar soil

9:57 am

In a press release this week Sierra Space revealed that it has successfully tested an extraction system that can gather up the abrasive lunar regolith and then heat it to high temperatures in order to extract and use the oxygen contained in that soil.

Temperatures in which the Sierra Space Carbothermal Oxygen Production Reactor were tested ranged from minus 45 degrees Celsius to 1,800 degrees Celsius. In addition to the challenges of functioning from sub-zero to hotter-than-lava temperatures, the hardware was required to move the simulated lunar regolith – a very abrasive and jagged material because it does not have the weathering processes found on Earth – through its system. The potentially damaging particles were handled effectively by the hardware and gasses were successfully sealed inside the reactor, thanks to Sierra Space’s use of a patent-pending valve design that previously demonstrated functionality to greater than 10,000 cycles.

The tests confirmed that Sierra Space’s system can successfully handle regolith that would be delivered from a lunar rover or robotic arm and automatically bring it into the reaction chamber, perform the carbothermal reduction reaction process to extract the oxygen from the minerals in the regolith, and remove the processed regolith from the system so the operation can be repeated.

This research is similar to the extraction system the Chinese are developing, though it appears Sierra’s system appears considerably closer to a finished product, as it is already being tested.

Eutelsat awards multi-launch contract with Mitsubishi

9:42 am

The French communications satellite company Eutelsat has awarded the Japanese company Mitsubishi a multi-contract using its H3 rocket.

The company did not reveal the contract amount or the number of launches involved. The first launches however will begin in 2027, with company officials explaining why they signed the deal.

The operator already has launches mostly covered for deploying its next-generation OneWeb broadband satellites in low Earth orbit (LEO), CEO Eva Berneke recently told SpaceNews. However, these launches include 3D printing specialist Relativity Space’s Terran R vehicle and Europe’s next-generation launcher Ariane 6, which have both already experienced development delays.

Ariane 6 is also part of the multi-billion-dollar launch campaign Amazon plans to kick off this year for its LEO constellation. “Given that Amazon has acquired Ariane 6 rockets, if we wanted to use it in, say, 2027, are we going to fit into their launch manifest or not?” Berneke told SpaceNews in the interview.

There are two interesting aspects to this deal. First, Eutelsat decided it needed to diversify its launch providers. The status of Relativity’s Terran-R rocket remains uncertain, and if it goes under Eutelsat would be left with just Ariane-6, which has its own issues and might not be able to meet the demand.

Second, Eutelsat clearly decided it did not want to give this business to SpaceX. I guarantee SpaceX’s price was less than Mitsubishi’s since the H3 is entirely expendable and very expensive, developed by Mitsubishi primiarly for the Japanese government (which paid the bills) and not as a player in the international launch market. Eutelsat made this choice for probably good and bad reasons. The good reason: All satellite companies need to encourage the success of as many launch providers as possible, to increase its options and competion. Giving business to Mistubishi serves that purpose.

The bad reason? Among many in Europe and elsewhere there is a childish resentment of SpaceX, simply because. No one will say so publicly, and if asked everyone will deny it, but the evidence clearly suggests that this silly emotional factor exists.

Musk: We will sue the FAA for “regulatory overreach” and “improper, politically-motivated behavior”

9:38 am

In a series of tweets yesterday Elon Musk announced that SpaceX is going to sue the FAA for its recent actions that have delayed development of Starship/Superheavy and have also fined the company for what appear to be petty reasons.

In the second case, the FAA threatened to fine SpaceX $633K because it had not gotten some minor approvals prior to successfully completing two launches safely. The agency gave SpaceX 30 days to respond.

Musk responded bluntly in a tweet, stating that “SpaceX will be filing suit against the FAA for regulatory overreach.” In a second tweet immediately thereafter Musk added that that the fines were “More lawfare.”

In a third tweet he stated unequivocally, “I am highly confident that discovery will show improper, politically-motivated behavior by the FAA.”

As noted in the first link above, the agency took no action against SpaceX for more than a year after those two launches, only issuing the threat to fine the company now, just before the election, and just after the company had publicly criticized the agency for its delays in issuing a launch license for the fifth Starship/Superheavy test flight. I suspect Musk has some good information of solid evidence that some officials either in the FAA or at the White House instigated this action for political reasons. An honest appraisal of the FAA’s actions sure suggests it.

NASA awards Intuitive Machines $4.8 billion contract to build Moon communication satellite constellation

9:17 am

NASA yesterday awarded Intuitive Machines a contract worth as much as $4.8 billion to build the communication relay infrastructure necessary to support bases and research on the Moon.

This Subcategory 2.2 GEO to Cislunar Relay Services is a new firm-fixed-price, multiple award, indefinite-delivery/indefinite-quantity task order contract. The contract has a base period of five years with an additional 5-year option period, with a maximum potential value of $4.82 billion. The base ordering period begins Tuesday, Oct. 1, 2024, through Sept. 30, 2029, with the option period potentially extending the contract through Sept. 30, 2034.

Lunar relays will play an essential role in NASA’s Artemis campaign to establish a long-term presence on the Moon. These relays will provide vital communication and navigation services for the exploration and scientific study of the Moon’s South Pole region. Without the extended coverage offered by lunar relays, landing opportunities at the Moon’s South Pole will be significantly limited due to the lack of direct communication between potential landing sites and ground stations on Earth.

According to the company’s own press release, this relay system will include a “lunar satellite constellation,” though the number of satellites was not revealed. The system will provide not just communications but will include GPS-type location data for ground operations.

SpaceX launches two more Galileo GPS-type satellites for Europe

12:43 am

SpaceX this afternoon successfully launched two Galileo GPS-type satellites for Europe, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its 22nd flight, landing on a drone ship in the Atlantic. The fairings flew their for their 3rd and 8th times respectively. The launch was the second launch by SpaceX for Europe’s Galileo constellation. The European Commission was forced to award this multi-launch contract to SpaceX because Europe’s Ariane-6 rocket was four years behind schedule and not available when needed.

The leaders in the 2024 launch race:

92 SpaceX
38 China
11 Russia

FAA fines SpaceX $633K for acting without its permission

12:46 pm

The FAA to SpaceX
The FAA to SpaceX “Nice company you got here.
Sure would be a shame if something happened to it.”

The FAA today revealed that it wants to fine SpaceX a total of $633,009 for two different actions where the company did something without the agency’s express permission.

In May 2023, SpaceX submitted a request to revise its communications plan related to its license to launch from Cape Canaveral Space Force Station in Florida. The proposed revisions included adding a new launch control room at Hangar X and removing the T-2 hour readiness poll from its procedures. On June 18, 2023, SpaceX used the unapproved launch control room for the PSN SATRIA mission and did not conduct the required T-2 hour poll. The FAA is proposing $350,000 in civil penalties ($175,000 for each alleged violation).

In July 2023, SpaceX submitted a request to revise its explosive site plan related to its license to launch from the Kennedy Space Center in Florida. The proposed revision reflected a newly constructed rocket propellant farm. On July 28, 2023, SpaceX used the unapproved rocket propellant farm for the EchoStar XXIV/Jupiter mission. The FAA is proposing a $283,009 civil penalty.

To understand the absurdity and abuse of power going on here, one must look at the dates. » Read more

France’s space agency aims to standardize its French Guiana commercial launchpad

9:04 am

France’s space agency CNES has announced a project to standardize its French Guiana commercial launchpad, which France owns and CNES now manages, for many different customers.

Launch facilities and launch pads in particular are generally specifically built for a single rocket. This will, however, not be the case with the Guiana Space Centre’s new commercial launch facility. As a result, a set of standardized ground systems will be utilized to ensure that the facility can manage a number of different rockets.

At the moment, those rockets include seven different European rocket startups — Avio, HyImpulse, Isar Aerospace, MaiaSpace, PLD Space, Rocket Factory Augsburg, and Latitude — none of which has yet launched a rocket. CNES is telling them all that if wish to use French Guiana, they must design their rocket to fit its facilities.

This project will accomplish two things. First, it will limit use of the pad to these European companies. CNES is essentially establishing French Guiana as a European-only facility. Second, like China’s commercial launchpads — run by that government so that all its pseudo-companies are dependent on it for launches — CNES (and France) is attempting to establish some control and power over these new independent and competing rocket companies, most of which have no facilities or operations in France. Three are German (Hyimpulse, Isar, and Rocket Factory), one is Spanish (PLD), and one is Italian (Avio). Only two are French-based (Latitude and MaiaSpace), with MaiaSpace a subsidiary of ArianeGroup which means it has facilities in many places in Europe. This project will force all these companies to cater their designs to the demands of France.

The American approach I think is far better. Government spaceports lease specific launchpads to specific companies, which then build the facilities to their needs, not the government’s. They can then each work fast and efficiently without consultation with others. CNES’s effort here will likely slow development in Europe, as all these companies will have to meet with CNES and work out some common engineering.

Investigation into upper stage failure during Ariane-6’s first launch completed

8:38 am

The Ariane-6 rocket investigation team, including people from the European Space Agency (ESA), CNES (France’s space agency), ArianeGroup (which built and owns the rocket), and Arianespace (which presently manages the rocket), has identified the issue that caused the rocket’s upper stage failure during the rocket’s first launch in July.

In a 16 September update, the Task Force announced that the investigation had identified a single temperature measurement that “exceeded a predefined limit” as the root cause of the anomaly. The tripped limit caused the software to trigger a shutdown of the APU which ensured the rocket’s Vinci upper stage engine could not be restarted for the final burn.

In order to remedy this issue and ensure a similar shutdown does not occur in the future, the ignition preparation sequence, specifically the APU chill-down sequence, has been changed. The updated flight software is already being tested as teams prepare for the rocket’s first commercial flight which is set to take place before the end of the year.

Because of that incorrect temperature, the upper stage did not do its final burn, thereby stranding the stage and two demonstration return capsules in the wrong orbit. This prevented the test return of both capsules, as well as the test planned de-orbit of the stage over the ocean.

Resilience splashes down safely, ending Polaris Dawn commercial manned orbital mission

12:48 am

SpaceX’s Resilience capsule has just splashed down safely in the Gulf of Mexico, ending the five-day Polaris Dawn private manned orbital mission, commanded by billionaire and jet pilot Jared Isaacman.

As of posting the capsule is still in the water with divers and boats on the way.

This completes the first mission in Isaacman’s planned three mission Polaris program. It was a complete success, doing a great deal of medical research on the effects of high orbit radiation on the human body as well as the first private spacewalk using SpaceX’s first EVA spacesuits. For Isaacman’s next mission he has already proposed doing a Hubble repair mission. NASA has had mixed feelings about this idea, but after this success it will be interesting if that attitude changes.

I must comment that the coverage by SpaceX employees on this mission was somewhat annoying. For the first time, they spent a lot of time giggling and focusing on PR and how “cool” and “incredible” and “wonderful” everything was, from amusing new decals in the capsule to the spacewalk to Sarah Gillis’ violin performance.

All of this was as great as they kept saying, which is why they didn’t need to say it, over and over and over and over and over again. It would have been better if they had done what SpaceX has generally done on previous broadcasts and missions, focused on describing the technical aspects and then staying silent otherwise. Gushing like this is more like a NASA or Blue Origin broadcast, and does not do SpaceX credit.
