Rocket engine startup Ursa Major enters solid-rocket motor business

Recognizing a desperate need of the military to ramp up production of solid rocket motors after much of its missile stockpile has been depleted by President Biden’s large gifts to the Ukraine, the rocket engine startup Ursa Major has now announced it is entering solid-rocket motor business.

Describing the solid rocket motor [SRM] market as “plagued by a broken supply chain and an overextended industrial base,” the Colorado startup today announced its plans to use its 3D printing techniques developed for liquid rocket engines to speed production of solid-fuel propulsion systems. Ursa Major has received several contracts from the Air Force Research Laboratory for its work on a new rocket engine for heavy space launch vehicles, as well as a hypersonic engine.

“Traditional SRM providers rely on production lines that are difficult to re-tool, expensive to ramp up, and dependent on a significant workforce to operate,” the company said in a press release touting its “new approach” to manufacturing, dubbed Lynx. “Ursa Major is offering a new way to scale production of SRMs,” Ursa Major CEO Joe Laurienti said in the press release. “Lynx meets the defense industry’s need for a faster, cheaper, scalable, and flexible SRM production process that results in better-performing solid rocket motors.”

The article also notes that at present the military is dependent on only two companies for new solid rockets, Northrop Grumman and Aerojet Rocketdyne (now L3Harris). The article also notes that it could take anywhere from five to eighteen years for these companies to replenish the depleted stocks.

The bottleneck however has brought several new players into the field, with the military eager to issue contracts to these new players. This decision by Ursa Major is thus a very good one.

India now plans robotic lunar sample return mission

Following the successful landing of Vikram on the Moon, officials of India’s space agency ISRO have announced it is considering a much more ambitious follow-up, Chandrayaan-4, that will not only land on the lunar surface with a much larger rover, it will also dig up some samples and return them to Earth.

The spacecraft will travel to the moon, land, collect samples, and then connect to another module in space. The module will then return to Earth orbit. As the two modules approach Earth, they will separate, with one part returning to Earth and the other will keep orbiting the planet. Desai described the mission as ambitious, stating, “Hopefully, in the next five to seven years, we will meet the challenge of bringing samples from the moon.”

For return to Earth, Desai said that the mission would need two launch vehicles containing four modules (Transfer module, Lander Module, Ascender Module and Re-entry module). RM and TM would be Parked in the lunar orbit and two will go down from which Ascender Module will get separated from lander module and would collect the sample.

If India does this mission, while also completing its first manned mission during that time frame, it will place itself in direct competition with China and the U.S., and in fact will be getting close to matching both in capabilities.

Musk: Next Starship/Superheavy test launch could happen in only 3 to 4 weeks

Superheavy & Starship, on their way
Superheavy & Starship, shortly after liftoff on November 18th

In a tweet on November 19, 2023, Elon Musk revealed that SpaceX could be ready for its next Starship/Superheavy test launch in only a matter of weeks, assuming federal red tape doesn’t get in the way.

Starship Flight 3 hardware should be ready to fly in 3 to 4 weeks. There are three ships in final production in the high bay (as can be seen from the highway).

In reporting on the second test launch on November 18, 2023, I noted that with prototypes ready to go SpaceX could probably launch within a month. Musk has now confirmed that assessment.

I also predicted that the FAA and Fish & Wildlife would not allow such a thing, and though they will determine there is no reason not to launch again, they will not issue a launch licence until the February/April time frame.

I want this prediction clearly on the record. It is important for the public to know the source of these delays.

It is also important for the press to apply pressure on these government paper pushers so they don’t feel encouraged in their intransigence. When I made a similar (and wholly accurate) prediction in May about the second launch, many in the press criticized that prediction (directly and indirectly) for daring to say bad things about government regulators. Now it appears that others in the press are no longer so naive, and are willing to note the slowness of the licensing process.

The regulators might not want to stand in the way and are simply following procedure. The press however mustn’t treat them gently. It must hold their feet to the fire to make sure they don’t take their time doing so.

Moreover, we have seen fewer headlines claiming falsely that the rocket “blew up” or “exploded.” Instead, a large percentage of the press now got it right and noted the mission’s success and that the destruction was not an accident but part of the self-destruct system.

After the last launch I lambasted the press for getting these facts wrong. Maybe holding their feet to the fire forced a reassessment and better reporting this time around.

Musk: Starship/Superheavy launchpad essentially undamaged after launch

Superheavy launchpad post launch
Click for original image.

In a tweet posted only a short time ago, Elon Musk announced that the redesigned and rebuilt Boca Chica launchpad experienced little or no damage during the launch of Superheavy/Starship on November 18, 2023.

Just inspected the Starship launch pad and it is in great condition!

No refurbishment needed to the water-cooled steel plate for next launch.

Congrats to @Spacex team & contractors for engineering & building such a robust system so rapidly!

Musk included the picture to the right in the tweet, showing the essentially undamaged launchpad pad. A close looks suggests there was some damage to the rear pillar near the top, but overall it appears the next launch could occur here very quickly.

Musk of course is wrong about who he credits for redesigning and rebuilding this launchpad. The real credit must go to the FAA bureaucrats who led the investigation and must have clearly guided those SpaceX engineers and contractors. To expect private citizens to think for themselves and come up with such difficult engineering without supervision from government paper-pushers in Washington is unreasonable and unfair. Maybe the Biden Justice Department should consider another lawsuit against Musk, this time for spreading more disinformation!

Moreover, who cares that the launchpad deluge system worked exactly as planned? We must allow Fish & Wildlife to spend several months now to investigate this launch — as well as write a long report of many words — to make sure that deluge of water did not harm any of the wildlife that lives on this barrier island, which has a water table of essentially zero and is flooded regularly and repeatedly by storms over time.

Anyone who disagrees is clearly a bigoted racist who wants to harm little children!

SpaceX launches 22 Starlink satellites

The beat goes on: SpaceX early this morning launched another 22 Starlink satellites, its Falcon 9 rocket lifting off from Vandeberg in California.

The first stage completed its 15th flight, landing successfully on a drone ship in the Pacific.

The leaders in the 2023 launch race:

85 SpaceX
52 China
14 Russia
7 Rocket Lab
7 India

American private enterprise now leads China 97 to 52 in successful launches, and the entire world combined 97 to 81. SpaceX by itself is now leads the rest of the world (excluding American companies) 85 to 81.

SpaceX successfully launches Superheavy and Starship

Superheavy & Starship, on their way
Note how all 33 Superheavy engines are firing.

SpaceX this morning successfully launched its Superheavy/Starship heavy lift rocket into its test orbit.

The test flight achieved far more than the first test in April. First, during the entire flight of Superheavy all 33 Raptor-2 engines fired normally. None cut out prematurely. Then at very risky hot fire stage separation — where the second stage (Starship) ignited prior to separation from Superheavy — the correct number of engines shut down, Starship’s engines fired, and Superheavy successfully separated and began its maneuvers for a soft splashdown in the Gulf of Mexico.

At that point mission controllers issued the self-destruct command to destroy Superheavy. Though it appeared that the stage was struggling to flip for its controlled return to Earth, it is also very likely that mission controllers wanted to test that flight termination system after its not perfect performance on the first test flight. Then, the self-destruct command did not activate the instant the command was given, being delayed by about 40 seconds. This time it appeared it worked as planned.

Researchers confirm it was a Chinese rocket stage that impacted Moon in 2022

Impact, before and after
The crash site is the double crater in the
lower image.

Researchers have now confirmed that the unknown rocket stage that impacted the Moon in 2022 was from a Chinese rocket, a Long March 3B that launched China’s Chang’e-5 lunar sample return mission in November 2020.

“In this paper, we present a trajectory and spectroscopic analysis using ground-based telescope observations to show conclusively that WE0913A is the Long March 3C rocket body (R/B) from the Chang’e 5-T1 mission,” the researchers, led by Tanner Campbell, a doctoral student in the UA’s Department of Aerospace and Mechanical Engineering, wrote in a study that came out Thursday (Nov. 16) in the Planetary Science Journal. These two lines of evidence — how the object was moving and what it was made of — leave little doubt about WE0913A’s provenance, Campbell and his colleagues report.

The data, combined with the unusual double crater caused by the impact, also suggests that this stage had additional unknown equipment at its top, matching the mass of its engines at the bottom. Since the Chinese continue to deny it was their stage and have said nothing about it, we have no idea what that extra equipment might have been.

German rocket startup signs deal with Norwegian spaceport

Map of northern European spaceports

The German rocket startup Isar Aerospace has signed a deal to provide the Andoya spaceport in the north of Norway with a new flight tracking and safety system, to be used by all launches including Isar’s own Spectrum rocket.

The purpose of the autonomous flight tracking system is to precisely and reliably keeping track of the Spectrum launch vehicle’s position, speed and direction of travel as it ascends to orbit, which is important to guarantee Andøya Spaceport’s flight safety requirements. The objective is to further evaluate the use of the system in enabling automated flight termination functionality for launches by Andøya Spaceport’s ground system, autonomously triggering an abort of the mission if ever operational parameters of the launch vehicle are out of bounds.

This announcement today illustrates the rising competition between German rocket startups and European spaceports. Yesterday the Saxavord spaceport in Scotland and another German rocket startup, HyImpulse, announced their own launch deal. Today’s announcement is the response from Andoya and Isar.

Today’s announcement also increases the pressure in the UK’s Civil Aviation Authority (CAA) to get its regulatory act together. Andoya is positioning itself as a good alternative to the two new British spaceports in Scotland, as shown by the red dots on the map above, should red tape in the UK slow launches there.

Sierra Space shakes up its staffing

Sierra Space yesterday did a major staffing shake up, laying off 165 workers while shifting 150 with secruity clearances from its parent company Sierra Nevada.

Sierra Space this week shipped the first Dream Chaser, named Tenacity, for pre-launch testing at NASA’s Armstrong facility in Ohio. The layoffs began soon after, the Sierra Space spokesperson said, noting the company conducted a surge in hiring this year to complete work on the Tenacity spacecraft.

With Tenacity shipped, Sierra Space’s spokesperson said the company is realigning to focus on the operations phase of Dream Chaser’s first mission, as well as on classified national security work. The latter part of Sierra Space’s realignment includes adding nearly 150 employees with security clearances from Sierra Nevada Corp., the aerospace and defense contractor owned by Fatih and Eren Ozmen, which the space company was spun out of two years ago. Sierra Space’s spokesperson said the company is creating a national security space team to work on several classified contracts.

This shift suggests that at least in the short run, Sierra is putting more focus on future military contracts rather than its civilian manned space projects like its LIFE space module (for the Orbital Reef space station) and future manner versions of its Dream Chaser mini-shuttle. I wonder if the company is having more internal doubts about Orbital Reef and its main partner, Blue Origin. Unlike the stations being built by Axiom and Voyager Space, which have already garnered contracts from both national and international customers, Orbital Reef has not done the same. There could be great doubts in the space community it will be built because of Blue Origin’s absymal record for building anything.

November 16, 2023 Quick space links

Courtesy of BtB’s stringer Jay, who notes it has been “a slow news day. I guess everyone is waiting to see SpaceX launch.” For me this has been good, as the day has mostly been tied up with doctors (nothing serious).

Amazon’s first two Kuiper satellites in orbit worked exactly as planned

Amazon announced today that its first two Kuiper satellites, launched into orbit by ULA’s Atlas-5 rocket on October 6, 2023, have worked exactly as planned, thus allowing the company to begin building operational satellites.

With the prototypes’ testing in space now complete, Badyal said Amazon plans to begin building the first production Kuiper satellites in December and launch the first satellites for its network in the “latter part of the first half” of 2024. Badyal emphasized that Amazon wasn’t sure what performance to expect from the prototype satellites, since “you don’t know how well it’s going to work in space.”

“They’re working brilliantly,” Badyal said.

The need of Amazon to start launching lots of satellites next year — in order to meet its FCC license requirements to put half of its 3,000+ constellation in orbit by 2026 — puts great pressure on ULA, Blue Origin, and Arianespace to get their new but as yet unlaunchd rockets operating. All three have big launch contracts with Amazon, but none presently appear to have the capability to meet the demands of those contracts.
