Touring the largest organ in the world

An evening pause: Specifically, this tour takes us from the bottom to the top of the largest pipe, and then shows us what comes out when you play it.

Hat tip Judd Clark, who provides this additional information:

Constructed between May 1929 and December 1932, the Main Auditorium Organ is the “Poseidon”, built by the Midmer-Losh Organ Company, and is the world’s largest pipe organ. Also included in this organ are pipes operating on 100 inches of pressure, the Grand Ophicleide being the loudest and also most famous. The instrument has an estimated 33,113 pipes and requires approximately 600 horsepower (450 kW) of blowers to operate.

Chinese company based in Hong Kong signs deal to build spaceport in Djibouti, Africa

Djibouti's location in Africa
Djibouti’s location is indicated in black.

The government of Djibouti, one of the smallest nations in Africa and located at the southern end of the Red Sea, has signed an agreement with a pseudo Chinese company, the Hong Kong Aerospace Technology Group, to build a major spaceport there.

According to the translated press release, the five year project will cost one billion dollars, include a lease for 30 years, and involve the construction of a port, highway, and electrical power distribution system.

As much as Hong Kong for more than two centuries has been a haven for private enterprise, it is now under the control of the communist Chinese, and they would not allow anyone from Hong Kong to make such a deal unless they were in full control.

Based on the map, there is almost no launch path out of Djibouti that will not cross another nation’s territory. Unless the Chinese plan to make all the first stages launched from this site reusable, they are going to dropping stages on a lot of people’s heads, without their permission. And they will be doing it to some places where war is often and continues to be the most frequently used negotiating tactic.

Hat tip to stringer Jay.

FCC votes to create its own space bureaucracy, despite lacking statutory authority

On January 9, 2023 the commissioners of the Federal Communications Commission FCC voted [pdf] to create its own space bureaucracy designed to regulate the lifespan of new satellites, despite lacking legal authority to do so.

As noted almost as an aside by this news article,

In order for the planned changes to go into effect, the FCC will first have to obtain congressional approval for the reorganization and place a notice in the Federal Register.

This vote pushed forward the plan announced in November that attempts to expand the regulatory power of the FCC beyond its legal authority. Expect Congress to push back somewhat, but right now most power in Washington is held by unelected bureaucracies like the FCC, not the elected legislators as defined by the Constitution. The FCC will continue to push hard, and mostly win in this power game. Congress right now is too divided and weak to fight back.

The result will be new regulations on satellite construction made by non-engineers and paper-pushers in the FCC, not engineers and managers in the companies actually building the satellites.

German rocket startup signs deal with UK spaceport

Rocket Factory Augsburg (RFA), a German rocket startup, has signed a deal with the SaxaVord spaceport in the Shetland Islands of Scotland to fly its first launch from there later this year.

Rocket Factory Augsburg (RFA) has signed a multi-year deal with the SaxaVord spaceport, being built in Unst, for the first launch of its satellite-carrying rockets. After testing at the site in mid-2023, it hopes to launch to a 500km orbit by the end of the year.

Because of the failure of the Virgin Orbit launch from Cornwall earlier this week, the honor of being the first orbital launch from within the United Kingdom remains ungrabbed. Both SaxaVord and Spaceport Sutherland, also in Scotland but at a different location, are now competing for that honor. Both now have planned launches this year, assuming the Civil Aviation Authority of the UK can issue a permit in less than fifteen months.

Meanwhile, Rocket Factory is competing with two other German startups for the honor of being the first commercial private European rocket company to reach orbit.

Saudi Arabia withdraws from Moon Treaty

On January 5, 2023, Saudi Arabia submitted its official withdrawal [pdf] from Moon Treaty, to be effective one year later.

The 1979 Moon Treaty is not the 1967 Outer Space Treaty, which almost all space-faring nations have signed. The Moon Treaty has been signed by almost no one because its language literally forbids private ownership.

In a sense, the Artemis Accords, which Saudi Arabia recently signed, is in direct conflict with the Moon Treaty, and no nation can really honor both. The Artemis Accords were designed by the Trump administration to get around the less stringent restrictions on private enterprise imposed by the Outer Space Treaty. That it has encouraged the Saudis to leave the Moon Treaty, however, suggests that the Artemis Accords might eventually cause a major abandonment of the Outer Space Treaty as well. To withdraw from such treaties up until now has been considered taboo. Saudi Arabia might have broken that spell.

If so, this action by the Saudis could be the best news for the future exploration and settlement of the solar system that has occurred in years, even more significant than that first vertical landing of a Falcon 9 rocket. It might finally force a major revision in the Outer Space Treaty so that each nation’s laws can be applied to its own colonies.

World View gets new lease from Pima County

Because the original lease was ruled unconstitutional under the Arizona state constitution, Pima County yesterday approved a new lease for the high altitude balloon company World View.

The original deal had the county build the building. World View would lease it for 20 years, guarantee employment of 400 people, and then buy the facility for $10 at the end of the lease. This was ruled unconstitutional.

Lesher said [the new lease] will give the county more flexibility and a safeguard when it comes to those terms and they’ll be able to base the appraisal price on a percentage of the fair market value. Another big change – the employee benchmark has been significantly lowered. In the original contract, World View was required to hire 400 workers, now that’s down to 125.

Until more details are provided, it is unclear what has changed to make the new deal acceptable to the courts. I suspect the big change is that World View will not have an option to buy for $10.

Leaking Soyuz to return empty; Unmanned Soyuz to be launched to replace it

The Russians announced today the plan to deal with the leaking Soyuz capsule on ISS as well as provide transportation back to Earth for its three astronauts.

First, the damaged Soyuz will return empty to Earth. Second, the next Soyuz will be launched in February unmanned so that it can bring back all three astronauts. Their mission however will likely be extended. Instead of returning in March as planned, they will stay in orbit until September, when that capsule was originally going to return to Earth. If this happens, it means their flight will end up being about a full year long. For the American in that crew, Frank Rubio, this could mean he will set a new American record for the longest spaceflight.

The Russians also added these details about the puncture in the Soyuz, which is believed to have been caused by a meteor:

According to calculations, a hole in the instrument compartment of the spacecraft, observed with a camera of the American ISS Segment, could be caused by a one-millimeter particle striking the vehicle with a speed of around 7,000 meters per second. Borisov also said that a possibility of a manufacturing defect in the radiator system of Soyuz MS-22 had also been evaluated but had not been confirmed.

ABL’s first launch attempt fails

The first launch of ABL’s RS1 rocket failed yesterday when the first stage engines shut down right after liftoff so that the rocket fell back onto the launchpad and exploded.

The company said in subsequent updates that the nine engines in its first stage shut down simultaneously after liftoff, causing the vehicle to fall back to the pad and explode. The company did not disclose when after liftoff the shutdown took place or the altitude the rocket reached. The explosion damaged the launch facility but no personnel were injured.

This rocket startup has raised several hundred million dollars, with its chief investor Lockheed Martin, which has also signed a contract for as many as 58 RS1 launches.

Starlink and National Science Foundation sign deal coordinating spectrum use

SpaceX and the National Science Foundation (NSF) today signed an agreement coordinating the use of radio spectrum so that Starlink satellites will not interfere with radio astronomy.

The National Science Foundation (NSF) and SpaceX have finalized a radio spectrum coordination agreement to limit interference from the company’s Starlink satellites to radio astronomy assets operating between 10.6 and 10.7 GHz. The agreement, detailed in a statement released by NSF today, ensures that Starlink satellite network plans will meet international radio astronomy protection standards, and protect NSF-funded radio astronomy facilities, including the National Radio Astronomy Observatory (NRAO) and the Green Bank Observatory (GBO).

This deal was part of a larger negotiation with the entire astronomy community to limit the problems caused to astronomy by the 3,000-plus Starlink satellites presently in orbit. These other actions include

…continuing to work to reduce the optical brightness of their satellites to 7th visual magnitude or fainter by physical design changes, attitude maneuvering, or other ideas to be developed; maintaining orbital elevations at ~700 km or lower; and providing orbital information publicly that astronomers can use for scheduling observations around satellite locations.

This agreement demonstrates again that SpaceX has tried hard to be a good citizen in this matter. It also illustrates once again that ground-based astronomical observations is becoming increasingly impractical. Astronomers have to go to space, and if Starship flies as SpaceX desires, the company will provide them a way to do it.

SpaceX successfully launches 40 OneWeb satellites

Using its Falcon 9 rocket, SpaceX tonight successfully placed 40 OneWeb satellites into orbit from Cape Canaveral, Florida.

This was only the second launch of this first stage, which landed successfully at Cape Canaveral. The rocket has now deployed all 40 satellites successfully, putting more than 80% of OneWeb’s constellation in orbit.

SpaceX had also planned a Starlink launch from Vandenberg in California tonight, but an hour before launch it was delayed until tomorrow.

At the moment only SpaceX and China have launched any satellites in 2023, and are both tied at 2 launches each.

Virgin Orbit launch a failure today from Cornwall, Great Britain

Five minutes after I posted the information below, Virgin Orbit’s announcer came on to announce that LauncherOne had suffered “an anomaly” and would not successfully place the satellites in orbit.

The failure must have occurred during a later stage after the rocket was released and was preparing for the second engine burn of its upper stage. They have ended the live stream without providing a further update, which is not surprising considering the data that needs to be analyzed.

Original post:
—————
Virgin Orbit today successfully completed the first orbital launch ever the United Kingdom, taking off from a runway in Cornwall, Great Britain, and then releasing its LaunchOne rocket from the bottom of a 747.

All in all 9 satellites were launched. This was Virgin Orbit’s fifth successful commercial launch, and hopefully will open a 2023 whereby the company will makeup for six months of bureaucratic red tape that essentially blocked about six launches last year. As of this writing the satellites have not yet deployed.

The 2023 launch race:

2 China
1 SpaceX

Two SpaceX launches coming later this evening.

Musk: SpaceX is now targeting late February/March for 1st orbital launch of Starship

According to a tweet put out by Elon Musk on January 8, 2023, SpaceX is now targeting late February/March for 1st orbital launch of the 24th prototype of Starship and the seventh prototype of Superheavy.

The testing in 2022 has not gone as smoothly as hoped, and is the reason no launch occurred last year:

Super Heavy B7 first left SpaceX’s Starbase factory in March 2022 and has been in a continuous flux of testing, repairs, upgrades, and more testing in the nine months since. The 69-meter-tall (~225 ft), 9-meter-wide (~30 ft) steel rocket was severely damaged at least twice in April and July, requiring weeks of substantial repairs. But neither instance permanently crippled the Starship booster, and Booster 7 testing has been cautious but largely successful since the rocket’s last close call.

Following its return to the OLS [orbital launch site] in early August, Super Heavy B7 has completed six static fire tests of anywhere from one to fourteen of its 33 Raptor engines. It has almost certainly dethroned Falcon Heavy to become the most powerful SpaceX rocket ever tested. And on January 8th, 2023, SpaceX rolled the rocket back to Starbase’s orbital launch site for the seventh time. According to statements made by CEO Elon Musk and a presentation from a NASA official, the last major standalone test between Booster 7 and flight readiness is a full 33-engine static fire. Together, B7’s 33 Raptor 2 engines could produce up to 7600 tons (16.7 million lbf) of thrust at sea level, likely making Starship the most powerful rocket stage in the history of spaceflight.

I had read speculation earlier that it was impossible for SpaceX to do a full 33-engine static fire test because the OLS could not hold the rocket down. That now appears to be incorrect.

Musk’s tweet and proposed schedule should also not be taken with great seriousness. He routinely sets ambitious targets merely to keep the pace fast, even if those targets are not met.
