Russia and SpaceX complete launches

9:08 am

Early today both Russia and SpaceX completed rocket launches.

First, Russia after several scrubs for technical reasons successfully completed a test launch of the largest configuration of its Angara rocket, the Angara-A5. It was the first launch of Angara-A5 from its far east spaceport Vostochny, and the first test launch of this rocket confiruration since 2014. Development had stalled for many years due to a major design issue revealed in 2019.

This launch establishes several important benchmarks for Russia’s space program. This rocket is essential for its goal of building a new space station, and the launch from Vostochny gives Russia as stronger backup to Baikonur in Kazakhstan, where long-term access is becoming problematic.

SpaceX then followed, with a launch of a military weather satellite, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its third flight, landing successfully back at Vandenberg.

The leaders in the 2024 launch race:

38 SpaceX
14 China
6 Russia
4 Rocket Lab

American private enterprise still leads the rest of the world combined 44 to 26, while SpaceX by itself still leads the rest of the world, including other American companies, 38 to 32.

Activists file lawsuit to prevent land swap at Boca Chica

2:51 pm

The same collection of activists who have been waging lawfare against SpaceX’s Boca Chica rocket facility have now filed a new lawsuit, this time against the Texas Parks and Wildlife Commission (TPWD) in order to block an approved land swap that gives SpaceX 43 acres of a Boca Chica state park in exchange for receiving 477 acres nearby.

The South Texas Environmental Justice Network, the Carrizo Comecrudo Tribe of Texas, and Save RGV banded together for a lawsuit filed in the District Court of Travis County on April 3. The suit alleges that Texas Parks and Wildlife violated statutory requirements for the proposal, including the requirement to consider alternatives to giving away public park land; the requirement to ensure the minimization of harm to the public park land; and the requirement to consider the best interests of the local community and TPWD.

These jokers represent very few people in south Texas. Worse, the so-called “Carrizo Comecrudo Tribe of Texas” was in Mexico, not Texas, when it existed. The corporation that exists now is a front for filing these lawsuits, taking advantage of the numerous DEI regulations that now exist to favor such minorities.

That the commission approved the swap unanimously, despite heavy pressure from these groups, illustrates the larger support in Texas for what SpaceX is doing. Expect the Texas courts to endorse that support as well. All these suits will do is delay, delay, delay.

Rocket Lab to refly a recovered first stage

2:31 pm

Electron 1st stage floating in the water

Rocket Lab today announced that a first stage used on a launch in January and recovered successfully from the ocean, as shown to the right, has now been moved into its normal production line for preparation for a reflight on an upcoming launch.

The stage was successfully launched and recovered as part of the ‘Four of a Kind’ mission on 31 January 2024 and has already passed more acceptance tests than any other recovered Electron stage, including:

  • Tank pressurization test – a process that filled the carbon composite tank with inert gas and held it in excess of maximum operating pressure for more than 20x longer than the standard Electron flight duration
  • Helium leak check – a stringent process that determines there are no leaks in the tank
  • Carbon fiber structural testing – including ultrasonic assessment and other non-destructive tests to confirm no delamination of the carbon composite tank fibers.

The stage will now undergo final fit out and rigorous qualification and acceptance testing to the same standard as a brand-new Electron tank to determine the recovered stage’s suitability for reflight.

No actual launch date has been set. The company first wants to complete its final testing. If successful and the stage flies again, Rocket Lab will join a very elite club, becoming only the second entity anywhere — after SpaceX capable of reusing a significant part of its rockets. That capability will allow it to drop prices, and better compete.

This success also underlines the lack of creativity from more than a half century of managers and rocket engineers, who repeatedly insisted such reuse was impractical, or impossible. The idea of recovering a stage from the ocean and reusing it was considered crazy, so no one ever tried it. Rocket Lab is about to prove more than a half century of managers and rocket engineers wrong.

Idiocracy has arrived

1:54 pm

Sheila Jackson-Lee:
Sheila Jackson-Lee: “The Moon is made up
mostly of gases!””

Over the last few days the conservative press has been having a field day making justifiable fun of a number of Democrats and leftists for exhibiting incredible scientifict ignorance, an ignorance so profound as to be mind-boggling.

First, after the unusual 4.8 magnitude earthquake centered in New Jersey on April 5th, a Green Party senate candidate in New Jersey, Christina Amira Khalil, immediately tweeted, “I experienced my first earthquake in NJ. We never get earthquakes. The climate crisis is real.” The mocking on X was so great she quickly deleted the tweet.

Then, in an incredibly embarrassing segment of the television show, The View, one host, Sunny Hostin, showed off her complete lack of any scientific knowledge when she claimed that the earthquake, the solar eclipse, and even the normal arrival of the cicadas every seventeen years (which she thought happened every hundred-plus years) was evidence that climate change was real.

Finally, to top off this stream of utter empty-headiness, during an eclipse event in Texas, Congresswoman Sheila Jackson Lee gave a speech of such stunning incompetency and lack of knowledge you have to wonder how she can figure out how to put on her clothes each day. This quote has been most often used to ridicule her:

China successfully tests new propulsion system for satellites

10:01 am

The state-run Chinese press today touted the successful use of a new “cold-propulsion system” on the Tiandu-2 test satellite launched into lunar orbit with its Queqiao-2 relay communications satellite.

The cold propulsion system recently provided high-precision orbital attitude control for the satellite during lunar orbit, marking the first successful application of the liquid ammonia cold air micro-propulsion system in the field of deep-space exploration.

The storage tank is an important component of satellite propulsion systems. As a pressure component, it requires not only high precision of forming and no leakage, but also good anti-fatigue performance, allowing for repeated fuel filling and discharge.

The article touts the tank so much because it was 3D-printed, making it the first such tank sent into space by China.

Angara launch scrubbed for the second day in a row

9:52 am

Technical issues early this morning caused Russia to scrub, for the second day in a row, the first launch of its new Angara-A5 heavy-lift rocket from its Vostochny spaceport in the far east of Russia.

The first attempt to launch the Angara-A5 rocket from the Vostochny spaceport on Tuesday was canceled about two minutes before the scheduled liftoff due to a failure of the pressurization system of the oxidizer tank in the central block [the core stage] of the rocket.

The second attempted launch Wednesday was also aborted by the automatic safety system, which registered a flaw in the engine start control mechanism, said Yuri Borisov, head of Russia’s state-controlled space corporation Roscosmos. He added that the failure was most likely rooted in a programming error.

They intend to try again tomorrow.

Angara has been under development for about two decades. This launch, which carries a dummy payload, will be the fifth launch of Angara, though the first of of the heavy-lift A5 configuration since 2014. In 2019 vibration issues were discovered that caused a major delay in its development. Of the previous four launches, only one carried an actual payload into orbit. All the others carried dummy payloads, with one test launch failing.

Russia needs the Angara-A5 rocket if it is going to build its own space station, because it no longer has the Proton rocket to launch modules. It also needs to get its Vostochny spaceport up and running, because its long term access to Baikonur in Kazakhstan is increasingly questionable.

Japan to sign deal with NASA to fly two Japanese astronauts to Moon

9:34 am

According to story in the Japanese press yesterday, a deal between Japan and NASA will be signed next week whereby Japan will have two astronauts go on Moon missions in exchange for providing cargo to the Lunar Gateway station as well as a manned lunar rover.

The report today is unclear whether those Japanese astronauts will land on the Moon, but I expect they will. The rover project is being led by Toyota. It will include a airtight cabin where spacesuits will not be necessary and passengers can also sleep, allowing for very long exploratory traverses from the landing site.

Reports of this deal have been appearing in the press since 2022, when NASA said it would involve flying one Japanese astronaut to the Moon. In December 2023 it was reported that the deal would be signed within a month. It is now April. It appears the extended negotiations have gotten Japan a second astronaut Moon walker.

NASA’s Artemis program is beginning to shape up as an international program for getting almost everyone to the Moon but Americans. I am exaggerating, but I think in the future Americans will find it easier to go on a private mission to the Moon than depend on NASA, especially because of all the international deals NASA will have to honor.

April 9, 2024 Quick space links

2:20 pm

Courtesy of BtB’s stringer Jay. This post is also an open thread. I welcome my readers to post any comments or additional links relating to any space issues, even if unrelated to the links below.

Note also that your host today is under the weather, so no culture/political column. I’m posting the quick links early also so I can hit the sack.

 

  • Video of Angara launch abort early today

    • The abort was caused by “a center core oxidizer tank pressurization system anomaly,” according to Roscosmos head Yuri Borisov. You can hear some sound burst at T-2:43, but there is nothing visible, so the sound could simply be some expected venting. They are going to try again tomorrow.
