An evening pause: Another guitar piece, but of a very different kind from yesterday’s.

Capitalism in space: Rocket Lab today successfully used its Electron rocket to 30 smallsats into orbit from its launchpad in New Zealand.
They also did their first launch test of their planned method for recovering the first stage for reuse. In their case the first stage will use parachutes to slow its descent, and will then be grabbed by a helicopter to be brought back to land. On this launch they were only testing the parachute portion of this plan, and allowed the stage to land in the water, where they then recovered it.
The leaders in the 2020 launch race:
30 China
20 SpaceX
12 Russia
5 ULA
5 Rocket Lab
The U.S. now leads China 33 to 30 in the national rankings.

Capitalism in space: Stratolaunch, continuing its shift from an orbital launch company to one providing a flying hypersonic testbed, has begun construction of its first hypersonic plane, dubbed Talon-A.
Talon-A will be air-launched from the bottom of Roc, the world’s biggest airplane, that the company initially built to serve as a launch platform for an orbital rocket.
It appears they have the financing to build Talon-A, and it also appears there is ample interest in both the military, NASA, and the aviation industry for this capability. If it works it will make testing hypersonic technology far easier and more affordable, issues that have acted to slow its development.
Capitalism in space: The new rocket company Relativity Space is in the process of raising another $500 million in new investment capital.
The new fundraise, expected to close in the coming days, would jump Relativity’s valuation to $2.3 billion, those people said. In addition to Tiger Global, Fidelity is also joining the round as a new Relativity investor. Existing investors in Relativity are also expected to be contributing — those include Social Capital, Playground Global, Y Combinator, Bond Capital, Tribe Capital, Jared Leto and Mark Cuban.
Tiger Global, the investment firm founded by Chase Coleman, has more than $43 billion in assets under management.
This new funding will supplement the almost $200 million Relativity raised previously.
The company has successfully completed engine tests, and plans its first orbital test launch of its Terran-1 rocket next year.
The first manned Dragon capsule, on the launchpad
Capitalism in space: During the post-launch press briefing after launch of its second manned Dragon mission on November 15, SpaceX CEO Gwynne Shotwell revealed the company’s plans to build and fly a fleet of Dragon cargo and crew capsules, and reuse them repeatedly over the coming years..
Specifically, Shotwell revealed that SpaceX intends to build three reusable Cargo Dragon 2 capsules, one of which is already completed and in Florida preparing for its December 2nd CRS-21 launch debut. On the crew side of things, SpaceX will build “three more” Crew Dragon capsules on top of the flight-proven Demo-2 and currently orbital Crew-1 capsules. It’s unclear if this means that the new Crew Dragon capsule flown on SpaceX’s January 2020 In-Flight Abort (IFA) test will be refurbished for additional flights.
Excluding IFA Crew Dragon capsule C205, SpaceX thus intends to operate a fleet of at least three Cargo Dragon 2 and five Crew Dragon capsules, representing eight reusable spacecraft each capable of at least five orbital missions.
She also hinted that the company has plans to fly its own missions, using these spacecraft, in addition to its contracted flights for NASA and the private company Axiom.
This private capability, which far exceeds anything ever built by NASA or any government worldwide, is entirely because Elon Musk had the freedom and the will to push for his particular vision. He had a bold idea, and with courage he pursued it.

Sierra Nevada officials revealed yesterday that they are delaying the first test flight of their Dream Chaser reusable cargo mini-shuttle from late 2021 to some unspecified time in 2022.
‘’COVID has definitely played a role” in that delay, said Steve Lindsey, senior vice president for strategy at SNC Space Systems. One example he gave involved structural testing of the spacecraft’s cargo module at a contractor’s facility in San Diego. COVID-related restrictions prevented SNC engineers from being on site at that facility to oversee the tests. SNC developed a workaround by using a mission control center it developed for Dream Chaser in Colorado so those engineers could remotely oversee those tests. “That worked great. Unfortunately, it took probably three or four times as long as it should have,” he said.
A related problem, he said, involves suppliers who have had to suspend operations because of COVID-19 outbreaks at their facilities. There have also been technical challenges with Dream Chaser, although he did not go into details about specific issues. [emphasis mine]
I underline the unspecified technical issues, because I suspect they might be the real issue. SpaceX has not been slowed in any significant way due to the Wuhan panic, even though it deals with NASA also. I would therefore not be surprised if they are using COVID-19 as a cover for other issues.
It is a new craft, and problems are expected. I’d just rather they didn’t hide it. It contributes to doubts about the company, which by the way has been much slower in its development than one should expect. NASA awarded this contract in January of 2016, with the first launch then planned for as early as October 2019. It is now 2020, and the launch is still now two years away.
According to Arianespace officials, today’s failure of their Vega rocket likely occurred because of “human error” in the installation of cables.
Engineers concluded that cables leading to thrust vector control actuators on the upper stage were inverted, apparently a mistake from the assembly of the upper stage engine, according to Roland Lagier, Arianespace’s chief technical officer. The thrust vector control system pivots the upper stage engine nozzle to direct thrust, allowing the rocket to control its orientation and steering.
The cabling problem caused the engine to move its nozzle in the wrong direction in response to commands from the rocket’s guidance system. That resulted in the rocket losing control and tumbling just after ignition of the upper stage engine around eight minutes after launch.
Lagier characterized the inverted cables as a “human error,” and not a design problem.
The next obvious question is the source of the error. The answer was not revealed, I think partly because of the number of contractors involved in building that upper stage:
The AVUM upper stage’s structure is produced by Airbus, and the Ukrainian rocket contractors Yuzhnoye and Yuzhmash supply the AVUM stage’s main engine, which consumes hydrazine and nitrogen tetroxide propellants. Avio, the Vega rocket’s Italian prime contractor, oversees final integration of the AVUM upper stage.
The goal of the investigation that will now follow will be to point that source among these contracts, and how their interaction might have contributed to it.
An evening pause: As the youtube webpage notes, “This is not an acoustic recording. This is a recording obtained by piano roll.”
Rolls for the reproducing piano were generally made from the recorded performances of famous musicians. Typically, a pianist would sit at a specially designed recording piano, and the pitch and duration of any notes played would be either marked or perforated on a blank roll, together with the duration of the sustaining and soft pedal. Reproducing pianos can also re-create the dynamics of a pianist’s performance by means of specially encoded control perforations placed towards the edges of a music roll, but this coding was never recorded automatically. Different companies had different ways of notating dynamics, some technically advanced (though not necessarily more effective), some secret, and some dependent entirely on a recording producer’s handwritten notes, but in all cases these dynamic hieroglyphics had to be skillfully converted into the specialized perforated codes needed by the different types of instrument.
Thus, we are listening now to a player piano, replaying the music as Debussy played it.

Capitalism in space: Virgin Galactic announced yesterday that it has canceled its announced November suborbital flight, claiming the cause were new COVID-19 guidelines imposed by the New Mexico Department of Health.
The flight had been scheduled for the November 19-23 time period. It had been announced with the typical hype that comes from Richard Branson.
Personally, I don’t believe Branson or Virgin Galactic as to the cause of this flight cancellation. I think they either never intended to fly, or have known for some time that new technical problems would prevent its launch as scheduled. I think they hyped the launch despite this, which conveniently pumped up the stock price at a time Branson was selling stock. They now announce the cancellation, the stock drops, but Branson has already pocketed his profits.
The timing of this announcement is also most ironic, as it occurred on the same day SpaceX docked four astronauts on ISS. Branson’s company began building its suborbital spacecraft in 2004, promising that it would soon fly hundreds, even thousands of private passengers into space. Sixteen years later it has never flown one passenger, and very few manned test flights. In the interim SpaceX built its Falcon 9 rocket and Dragon capsule, and is now launching passengers to orbit, with its first entirely private launch scheduled less than a year from now.
The comparison is quite stark. Why anyone would invest real money in this fake company at this point baffles me.
Capitalism in space: Axiom has revealed that an Israeli fighter pilot, Eytan Stibbe, will be the second passenger on on its first private Dragon launch to ISS in the fall of 2021.
Stibbe will be the second Israeli to fly in space, following Ilan Ramon, who died when the space shuttle Columbia broke up in 2003 during its return to Earth.
The Axiom AX-1 mission is scheduled to launch in the second half of 2021, which the company unveiled in a deal with SpaceX earlier this year. Astronaut Michael Lopez-Alegria, who previously worked for NASA and flew to space four times, will be the AX-1 mission commander, with Stibbe set to serve as a mission specialist.
AX-1 would be the first fully private mission to the International Space Station, with Lopez-Alegria and Stibbe flying with two other yet-to-be-named people.
The consistent rumors are that actor Tom Cruise and a movie director will be those other two passengers, but this is not confirmed.
It is important to emphasize that this space mission will be entirely private, with almost no involvement of the U.S. government other than providing coordination, the training of the astronauts, and the use of ISS. The rocket and spacecraft are SpaceX’s, purchased by the customer Axiom. Moreover, Axiom has plans to add its own private modules to ISS where future private space passengers will be housed, which will then reduce the government’s role and contribution even more.
And since this will be a private mission, it means the funds to fly it will come from its passengers, not the government. This also means that as long as there are customers, there will be no slow-down in future flights.
SpaceX’s Resilience Dragon capsule successfully docked with ISS tonight.
They are in the process of checking the seal of the docking, and the opening of the hatch.
As much as I have been critical of Boeing in recent years, I truly hope they can get their management and engineering problems worked out so they can accomplish the same thing with their Starliner capsule. The competition with SpaceX will be healthy for both companies, the nation, and the future of the human race.
An evening pause: I normally don’t post two suggestions in a row from the same reader, but this particular collapsible (!) guitar contrasts too nicely with Friday’s theorbo. From the youtube webpage:
If the ability to break down and re-assemble wasn’t crazy enough, it actually STAYS IN TUNE when you put it back together, thanks to the air-tight construction techniques and locking tuners!

Capitalism in space: SpaceX tonight successfully launched four astronauts to ISS on its Dragon capsule Resilience, using its Falcon 9 rocket.
They also recovered the first stage, landing it on its drone ship in the Atlantic. The routine manner in which SpaceX ran this launch is truly admirable. They make landing and reuse of the first stage so expected it is hard to believe that for fifty years rocket managers and engineers insisted it wasn’t doable.
They had one issue today, a failure of the capsule hatch to hold air pressure after closure. They calmly reopened the hatch, cleared the issue, added some lubricant, and closed the hatch, all in less than ten minutes.
Resilience will dock with ISS tomorrow evening.
The leaders in the 2020 launch race:
30 China
20 SpaceX
5 ULA
4 Europe (Arianespace)
4 Rocket Lab
The U.S. now leads China 32 to 30 in the national rankings.
According to a NASA report yesterday, the weather then stood at 50% for allowing a launch of four astronauts to ISS on SpaceX’s Resilience capsule tonight at 7:27 pm (Eastern).
That percentage was still reported this morning. Part of the issue is that SpaceX wants to recover the first stage, and the weather therefore not only has to be good in Florida, it has to be good in the Atlantic where the stage will come down.
NASA’s live coverage begins at 3:15 pm (Eastern). The link to that live stream is below the fold. As I write this at around noon (Eastern) it is simply NASA TV’s normal feed, which is essentially full time propaganda for NASA. After 3:15 pm it will switch to live coverage, which unfortunately will still be packed with pro-NASA propaganda, even though this launch is entirely being run by the private company SpaceX. NASA’s only part is that of a customer, with the ability to say “no” at any point. The rocket, the capsule, the launchpad, and the countdown, is operated completely by SpaceX and its employees.
I have also added the clean feed from NASA, which appears to carry little commentary or narration.
Because of issues in Rocket Lab’s flight termination system (used to destroy the rocket should it go out of control during launch), the company has announced that its first U.S. launch will be delayed until 2021.
One reason for the delay, Rocket Lab said, was that it was waiting on NASA to certify the autonomous flight termination system (AFTS) that will be used on the rocket to provide range safety. NASA controls the launch range at the Wallops Flight Facility, where LC-2 is located. “There’s a very long certification process that, quite frankly, we probably underestimated how long it would take,” Peter Beck, chief executive of Rocket Lab, said in an interview in August.
That certification process is ongoing. In a Nov. 10 talk at a Maryland Space Business Roundtable webinar, David Pierce, director of NASA Wallops, mentioned preparations for Rocket Lab’s first launch as part of an overview of the facility’s activities. “We’re really proud of our work with Rocket Lab,” he said. “We’re working really hard to support Rocket Lab with a launch in ’21.”
Asked later about the certification of the AFTS, Pierce said that engineers had kept on schedule with the development of the system into the summer despite the pandemic. “When they sent the unit out for review of the software, we found some errors,” he said. That review involved teams at NASA’s Katherine Johnson Independent Verification and Validation Facility, the Federal Aviation Administration, Vandenberg Air Force Base and Cape Canaveral Air Force Station.
While I have no evidence of this, I cannot help being suspicious of these various government agencies. For years numerous people in the government put fake roadblocks up to slow or stop SpaceX’s first manned launch, merely because it threatened their turfs. This autonomous termination system will make the ground crews at Vandenberg and at Cape Canaveral irrelevant, and I would not be surprised if some of these issues were drummed up to delay or block this system because of that.
I know I am being cynical, but based on history it is not unreasonable to be so.
Capitalism in space: The most recent engine test on November 12th of SpaceX’s eighth Starship prototype had a problem that will delay its planned 50,000 foot test hop.
The Starship SN8 vehicle performed its third brief “static fire” — a test in which engines are ignited while a rocket remains tethered to the ground — at SpaceX’s South Texas facility on Thursday, near the village of Boca Chica.
Shortly after the test, which several outside organizations webcast live, material could be seen apparently dripping from SN8’s base. This looked odd, and SpaceX founder and CEO Elon Musk soon confirmed that something off-nominal had happened. “We lost vehicle pneumatics. Reason unknown at present. Liquid oxygen header tank pressure is rising. Hopefully triggers burst disk to relieve pressure, otherwise it’s going to pop the cork,” Musk said via Twitter on Thursday night. (Burst disks are single-use devices that, like valves, seal off different sections or systems of a vehicle. They relieve pressure when they open, as Musk noted.)
The cause of the problem is unknown at the moment, Musk said in another Thursday tweet: “Maybe melted an engine preburner or fuel hot gas manifold. Whatever it is caused pneumatics loss. We need to design out this problem.”
The decision to pin down the cause and redesign things so it won’t happen again makes perfect sense, but it also means that the hop will not occur in the next week or so, as hoped for by the company. Expect a delay. Based on the pace that SpaceX works, that delay however should not be longer than one or two months.
Because of high winds and ocean weather interfering with the recovery of the first stage, NASA and SpaceX today decided to delay the launch of SpaceX’s second manned Dragon mission, the capsule Resilience carrying four astronauts, to Sunday, November 15.
NASA and SpaceX are now targeting 7:27 p.m. EST Sunday, Nov. 15, for liftoff of the agency’s SpaceX Crew-1 mission to fly astronauts from Launch Complex 39A at NASA’s Kennedy Space Center in Florida to the International Space Station.
Teams moved the launch by one day because of onshore winds and to enable recovery of the first stage booster, which is planned to be reused to launch the Crew-2 mission next year. The booster is expected to land on the recovery ship about nine minutes after launch.
They now plan to dock with ISS at 11 am (eastern) on November 16th.
An evening pause: The music was written in the early 1600s by G.G. Kapsberger. The instrument is called a theorbo. I posted a different performance featuring this medieval instrument in 2019, in which the instrument’s origins is described. In both cases the quality of sound is hauntingly wonderful..

Capitalism in space: ULA today successfully launched a military reconnaissance satellite using its Atlas 5 rocket.
This launch was the first Atlas 5 using these particular Northrop Grumman solid rocket boosters.
Because this was a military launch, the live broadcast ended at the moment the fairings were released, exposing the satellite. Final announcement of the satellite’s successful deployment will come later, assuming all goes well.
The leaders in the 2020 launch race:

19 SpaceX
5 ULA
