Updates on Starship development: next 50K foot flight this weekend?
Two different updates yesterday and today on the development of Starship by SpaceX suggest strongly that the company is aiming for its next test flight to about 50,000 feet as early as this coming weekend.
- Starship SN9 speeds toward Static Fire and test flight
- SpaceX scraps Starship SN8 wreckage, clears landing zone for next launch
The second story notes how the company has apparently decided it was not worthwhile keeping much of the debris left over from the crash of the eighth Starship prototype after its successful test flight on December 9th. They have instead focused entirely on clearing the landing pad as quickly as possible, even if it meant destroying some of the prototype’s remains.
The first story outlines the ongoing pressure tests for the ninth prototype, now on the launchpad, and how those tests have so far proceeded very smoothly. All that remains is SpaceX’s standard dress rehearsal countdown ending in a static fire test of the prototype. This is presently scheduled for tomorrow. Once it is accomplished, the test flight can follow quickly, probably no more than a week later, depending on weather, the data from the static fire test, and the innumerable uncertainties that routinely occur in a robust test program such as this.

The state of the global rocket industry in the 21st century
With the year of 2020 coming to an end, it is time to look back to see how the world’s rocket industry fared in what was a truly difficult year for most. And with the 21st century now one fifth over, it is also time to take a wider view, to see what the trends have been for space exploration during this new century, and to see where those trends might lead.
Below is my annual updated table showing all successful orbital launches by every nation and company, beginning in 2000. While the table in my 2019 report last year had gone back to 1990, I decided to shorten the graph to just the 21st Century, in order to better focus on that century in particular.
Musk: Super Heavy will land on launchpad, caught by launch tower
Capitalism in space: In a series of tweets yesterday SpaceX founder Elon Musk revealed that the company is considering landing Starship’s first stage, Super Heavy, on its launchpad but rather than use landing legs it will be caught by the launch tower.
Instead, Musk says that SpaceX might be able to quite literally catch Super Heavy in mid-air, grabbing the booster before it can touch the ground by somehow slotting an elaborate “launch tower arm” underneath its steel grid fins. Although such a solution sounds about as complex and risky as it gets, it would technically preclude the need for any and all booster recovery infrastructure – even including the legs Super Heavy would otherwise need.
While true, catching Super Heavy by its grid fins would likely demand that control surfaces and the structures they attach to be substantially overbuilt – especially if Musk means that the crane arm mechanism would be able to catch anywhere along the deployed fins’ 7m (23 ft) length. Even more importantly, it seems extraordinarily unlikely that such a complex and unproven recovery method could be made to work reliably on the first one or several tries, implying that early boosters will still need some kind of rudimentary landing legs.
The idea is to save weight on the booster. It also would speed its reuse, as there would no longer be a need to transport it from a landing pad back to the launchpad.
Whether this will work will depend on the accuracy of SpaceX’s vertical landing software. That the company has repeatedly proven, from almost the first time it tried it, that it can bring its rockets down exactly where it intends suggests they will be able to be as accurate as necessary.
Nonetheless, expect more than a few launchpad crashes as they work out the kinks on another audacious engineering concept.

Indian private company test fires its own solid rocket motor
Capitalism in space: Skyroot Aerospace, an Indian private company, has successfully test fired its own privately-built solid rocket motor, as part of an effort to develop its own private rocket dubbed Vikram, with its first launch set for December ’21.
The solid rocket motor is for either the rocket’s second stage or for strap-on boosters. The company has already successfully tested the first stage engines.
The most interesting quote from the story however is this:
Founded by former scientists of the Indian Space Research organization (ISRO), Skyroot has raised $4.3 million till now and is in process of raising another $15 mn in 2021. In the past the company has raised investments from: Mukesh Bansal (Founder Myntra, CureFit), Solar Industries (India’s largest explosives manufacturer and renowned Space & Defence Contactor), Vedanshu investments and a few other Angel investors.
The Modi government has been making a strong effort to mimic the transition that NASA has gone through in the past decade whereby it shifts from having all its spacecraft and rockets designed, built, and owned by the government to having the government act merely as the customer buying those products from privately-run and independent companies. Like NASA, there has been strong resistance to this change within India’s government bureaucracy. Skyroot’s success, including its foundation by former ISRO engineers, is a very good sign that they are overcoming that resistance.

Starship #9 update: 1st flight targeted for shortly after the new year
Capitalism in space: According to this nasaspaceflight update, the first 10-mile-plus flight of the ninth Starship prototype is now targeted for shortly after January 1st.
Starship SN9 has been undergoing integration ops on the launch mount over the Christmas holiday, setting the stage for what will be a streamlined pre-launch test series when compared to that undertaken by SN8.
The first test will involve filling the vehicle with nitrogen, usually in a two-step fashion. Initially, the vehicle will be filled with gaseous nitrogen – called the ambient test, ahead of being loaded with super-cold liquid nitrogen (LN2) for the cryo test. This test sequence is expected early in the coming week, with preparations for testing already ongoing on Monday morning.
Providing all goes to plan with the proofing test, SN9 will be prepared for what is currently expected to be one Static Fire test involving all three Raptors. This is an expedited test schedule compared to SN8, which underwent several Static Fire tests ahead of launch. Two of SN9’s Raptors were installed on the vehicle inside the High Bay. Once the vehicle had made it to the pad, a third engine – SN49 – was installed, completing the trio.
Only after these tests have been completed will a launch date become known, likely via a notice to local air and sea traffic. This, in turn, will be pending acceptable weather conditions and vehicle preparedness going into prop loading tasks. Based on the best-case scenario test flow, the launch could realistically occur within January’s first two weeks.
The goal on this flight likely be will be twofold. First, to reaffirm the engineering and software for controlling the stage during its return to Earth. Second, to complete a successful landing, to prove they have corrected the pressure issue that caused the landing failure during Starship prototype #8’s flight.
The article also gives an update on the many additional Starship prototypes being readied for flight, along with the first Super Heavy prototype. It is expected that Super Heavy will make its first short 500 foot hop sometime in ’21.

Nanoracks’ commercial airlock installed on ISS
Capitalism in space: Using the robot arm on ISS, astronauts on December 21st installed Nanoracks’ commercial airlock, dubbed Bishop, in its place on the station.
I think this is the second private module installed on ISS, following Bigelow’s inflatable BEAM module. Bishop is for equipment only, and supplements the equipment airlock on the Japanese Kibo module. It is also five times larger, and rather than use hatches, it deploys equipment outside of ISS using the robot arm. Each time Nanoracks wants to use it to deploy a commercial cubesat they will use the arm to unberth Bishop, deploy the satellite through the docking port, and then re-berth it.
Bishop and BEAM are harbingers of the future on ISS. Axiom will be adding its own private modules in ’24. And then there are the upcoming private tourist flights. Both Axiom (using Dragon) and Russia (using Soyuz) have such flights scheduled before the end of ’21.
Assuming the economy doesn’t crash due to government oppression and mismanagement, gradually over the next decade expect operations on ISS and future stations to shift from the government to commercial private operations, aimed at making profits instead of spending taxpayer money.

Axiom chooses Houston for its astronaut training and space station construction facility
Capitalism in space: Axiom, the company building the next private modules to be added to ISS, has chosen Houston as the location for its astronaut training and space station construction facility.
Axiom Space, based in Houston, plans to develop a 14-acre headquarters campus at the spaceport located at Ellington Airport. It will use this campus to train private astronauts and for production of its Axiom Station. Mayor Sylvester Turner announced the project on Tuesday.
…Terms of the deal, including how the development would be financed, are still being worked out and must be approved by City Council. The Houston Airport System, for instance, could help provide financing that Axiom Space would pay back.
Axiom said construction could begin in 2021, and it expects to have a functional headquarters campus in 2023. The company grew its workforce to 90 people this year and is looking to hire another 100 next year. Ultimately, it could add more than 1,000 jobs for the Houston area.
For Axiom, the most important event in the coming year will be its private manned mission to ISS, using SpaceX’s Dragon capsule. That flight, presently scheduled for the fall, will put it on the map.

SpaceX puts Starship prototype #9 on launchpad
Capitalism in space: Less than two weeks after Starship prototype #9 had fallen off its stand and hit the side of the assembly building, damaging its fins and hull, SpaceX has repaired the damage and moved the prototype to the launchpad in preparation for its test flight, expected sometime in the next three weeks.
The pace that SpaceX operates continues to astound, though in truth it is the right pace. If more American companies (as well as Americans) emulated it, many of the problems the country now faces would vanish.

Lockheed Martin buys Aerojet Rocketdyne for $4.4 billion
Capitalism in space: Lockheed Martin officials announced yesterday that it will buy the rocket engine company Aerojet Rocketdyne for $4.4 billion.
James Taiclet, Lockheed Martin’s president and CEO, said the acquisition gives the company a larger footprint in space and hypersonic technology. He said Aerojet Rocketdyne’s propulsion systems already are key components of Lockheed Martin’s supply chain across several business areas. “The proposed acquisition adds substantial expertise in propulsion to Lockheed Martin’s portfolio,” the company said in a news release.
Aerejet Rocketdyne has been in trouble because it has had problems finding customers for its engines. This acquisition will give Lockheed Martin more technical capabilities should it decide to enter the launch industry with its own rocket.

SpaceX completes 25th orbital launch in 2020
Capitalism in space: SpaceX today successfully completed its 25th orbital launch in 2020, using its Falcon 9 rocket to put an American spy satellite into orbit.
The first stage successfully landed at Cape Canaveral, completing its fifth flight.
Not only is 25 launches in a single year a new record for SpaceX, it is also four more launches than the company predicted it would achieve in 2020.
This was also the 40th successful American orbital launch in 2020, the first time since 1968 that the U.S. has had that many launches. In 1968 the launches were almost all dictated by the government, on rockets controlled by the government. Today, the rockets are all privately designed and owned, with the small number of government launches occurring with the government merely the customer buying a product.

The U.S. now leads China 40 to 33 in the national rankings. The rankings also should not change significantly in the last two weeks of the year, as the U.S. has no more scheduled launches and China and Russia only one.

First flightworthy BE-4 engine delivery now expected in summer ’21
Capitalism in space: Tory Bruno, the CEO of ULA, revealed yesterday that Blue Origin will finally deliver two flightworthy BE-4 engines for ULA’s Vulcan rocket this coming summer.
ULA, the Pentagon’s top launch contractor for national security satellites, had initially expected the shipment in 2020 for a debut flight in early 2021, but this was delayed by development hurdles.
The installation of Blue Origin’s reusable BE-4 engines into ULA’s next-generation Vulcan rocket will keep it on track for the debut launch of a moon lander dubbed Peregrine at the end of 2021, ULA Chief Executive Tory Bruno said. The Vulcan rocket has won a slate of key U.S. defense missions through 2027.
“That is now our expectation, that Peregrine will go to space in the 4th quarter of 2021,” Bruno told reporters during a call on Thursday.
Peregrine is a commercial lunar lander being built by Astrobotic for NASA.
More information here.
It appears that ULA thinks the long delay in engine development and delivery from Blue Origin will not delay the planned first launch of Vulcan later in ’21. It appears their long range plan to recover and reuse these engines has caused them to design Vulcan so that they can easily swap out engines, which will allow them to complete that new rocket’s development with the test engines that Blue Origin has already provided, and then switch engines and launch within months.
During Bruno’s press briefing he also noted that they have done a thorough refurbish of the Delta launchpads and have instituted a new policy requiring regular launchpad dress rehearsals, in order to make sure the series of problems that delayed the launch of a Delta-4 Heavy earlier this year will not reoccur.

ESA confirms cause of November Vega launch failure
The European Space Agengy (ESA) has now completed its full investigation of a Vega rocket launch failure in November, and confirmed that the initially announced cause of “human error” was correct.
Engineers had installed cables backwards causing the nozzle in the upper stage to go one way when it should have gone the other.
The press release at the link is a wonder of bureaucratic cover-your-behind gobbly-gook, saying much without providing any concrete information about the corrections imposed. For example, the upper stage structure is built by one company, Airbus, the engine is built by two Russian companies, Yuzhnoye and Yuzhmash, while a fourth company, Avio, supervises the stage’s assembly. The press release makes it a point to not tell us where the error was made by which company, though by vague implication it suggests the error occurred during final assembly by Avio.
If I was a satellite company thinking of buying a Vega launch I would demand a much more straight-forward explanation. Otherwise I’d go elsewhere.

Using origami to design spaceship fuel bladders
Capitalism in space: Engineers at Washington State University have developed a new design for a collapsible fuel bladder for spaceships using as its basis the Japanese art of origami.
Washington State University researchers have used the ancient Japanese art of paper folding to possibly solve a key challenge for outer space travel – how to store and move fuel to rocket engines. The researchers have developed an origami-inspired, folded plastic fuel bladder that doesn’t crack at super cold temperatures and could someday be used to store and pump fuel.
The advantages of a fuel tank that will shrink as it empties are numerous. It appears that nothing that has been tried so far has worked as well as this new design. If proven viable, it will change radically how interplanetary spaceships are designed. It will also make interplanetary missions more practical.

Washington State University researchers have used the ancient Japanese art of paper folding to possibly solve a key challenge for outer space travel – how to store and move fuel to rocket engines. The researchers have developed an origami-inspired, folded plastic fuel bladder that doesn’t crack at super cold temperatures and could someday be used to store and pump fuel.
The advantages of a fuel tank that will shrink as it empties are numerous. It appears that nothing that has been tried so far has worked as well as this new design. If proven viable, it will change radically how interplanetary spaceships are designed. It will also make interplanetary missions more practical.
