Airbus forced to write off almost a billion dollars

9:42 am

Even though the problems that Boeing has been driving its customers to Airbus, Airbus yesterday revealed that its own business outlook is presently suffering, forcing it to write off $965 million.

Yielding to growing scepticism among suppliers over its plans for jet output, Airbus lowered its widely watched forecast for deliveries this year to around 770 jets from around 800. It also tempered plans to raise output of its best-selling A320neo family, by delaying the date at which it expects to reach a record production speed of 75 jets a month to 2027 from 2026. That compares with an estimated 50 jets a month now.

As a result of the lower delivery forecasts, which imply annual growth of 5% instead of 9%, Airbus lowered its main financial targets for 2024. It now expects underlying operating income of around 5.5 billion euros, instead of a range of 6.5 billion to 7.0 billion, and free cashflow of 3.5 billion instead of 4.0 billion.

The article focuses on Airbus’s engine supply issues that are restricting its ability to build jets. It makes no mention of the company’s joint partnership with Safran to build the Ariane-6 rocket, which has failed to garner the business predicted, even as it is about to make its inaugural launch on July 9th. Though peripheral to the airplane issues described, it is certainly a factor in these financial issues.

Scientists surprised by new Webb data of the upper layers of Jupiter’s Great Red Spot

The uncertainty of science: Using the Webb Space Telescope, scientists have obtained infrared data of the upper layers of Jupiter’s Great Red Spot, revealing that it is far more complicated that predicted by researchers.

The upper atmosphere of Jupiter is the interface between the planet’s magnetic field and the underlying atmosphere. Here, the bright and vibrant displays of northern and southern lights can be seen, which are fuelled by the volcanic material ejected from Jupiter’s moon Io. However, closer to the equator, the structure of the planet’s upper atmosphere is influenced by incoming sunlight. Because Jupiter receives only 4% of the sunlight that is received on Earth, astronomers predicted this region to be homogeneous in nature.

The Great Red Spot of Jupiter was observed by Webb’s Near-InfraRed Spectrograph (NIRSpec) in July 2022, using the instrument’s Integral Field Unit capabilities. The team’s Early Release Science observations sought to investigate if this region was in fact dull, and the region above the iconic Great Red Spot was targeted for Webb’s observations. The team was surprised to discover that the upper atmosphere hosts a variety of intricate structures, including dark arcs and bright spots, across the entire field of view.

You can read the published research paper here. The image to the right is figure 4 from that paper, with each panel showing different infrared wavelengths indicated by the different colors, and thus the complex structures and physical properties.

Firefly to launch from Wallops instead of Cape Canaveral

9:18 am

The rocket startup Firefly announced yesterday that it has decided to change its east coast launch site for its Alpha rocket from Cape Canaveral in Florida to Wallops Island in Virginia, using the same pad there that Northrop Grumman’s Antares rocket uses.

The company said that it would use Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island for Alpha launches, starting as soon as 2025. The launch pad, built for the Antares rocket, will continue to be used for the revised Antares 330 Northrop Grumman is developing in collaboration with Firefly as well as the larger Medium Launch Vehicle (MLV) the companies are building.

The company says launching from Wallops, in addition to its existing pad at Vandenberg Space Force Base in California, will allow it to serve more customers. Wallops can support launches to lower inclination orbits than feasible from Vandenberg, which is best suited for sun-synchronous and other high-inclination orbits.

Because the revised Antares rocket will use a first stage built by Firefly (replacing a Ukrainian first stage no longer available due to Russia’s invasion), this change appears to make a great deal of sense. The revised pad will likely use comparable systems between both Antares and Alpha.

According to China’s state-run press, the sample return capsule of its Chang’e-6 lunar mission successfully landed today in the inner Mongolia region of China, bringing back the first lunar samples from Moon’s far side.

Under ground control, the returner separated from the orbiter approximately 5,000 km above the South Atlantic. The capsule entered the Earth’s atmosphere at about 1:41 p.m. at an altitude of about 120 km and a speed of nearly 11.2 km per second. After aerodynamic deceleration, it skipped out of the atmosphere and then began to glide downwards, before re-entering the atmosphere and decelerating for a second time.
At around 10 km above the ground, a parachute opened, and the returner later landed precisely and smoothly in the predetermined area, where it was recovered by a search team.

The returner is set to be airlifted to Beijing for opening, and the lunar samples will be transferred to a team of scientists for subsequent storage, analysis and study, said the CNSA. [emphasis mine]

The highlighted sentence is important. China has now successfully flown this atmospheric skip maneuver twice on returning from the Moon. Though both missions were unmanned, the technical knowledge gained from these flights is critical for their plans to send astronauts to the Moon in the next few years.

I have embedded China’s broadcast of the landing below. The sample capsule will now be carefully opened and the samples distributed first to Chinese scientists and later to China’s various partners in its lunar base project. The samples themselves came from a small mare region on the edge of Apollo Crater inside South Aitken Basin, one of the largest impact basins on the Moon. It is thus hoped that the samples were excavated from deep within the Moon during the impact, and will provide new data on the Moon’s make-up and history.

Reparations: Taking money from people who never owned slaves and giving it to people who never were slaves

12:48 pm

Harvard: where you get can get a shoddy education centered on hate and bigotry
Harvard: where you can spend a lot of money
getting a shoddy education teaching hate and bigotry

The effort to justify the new fad of forcing all Americans today to pay blacks reparations for the evil of slavery that was eliminated a century and a half ago at the cost of more than 600K lives continues. A recent published study by two “Didn’t Earn It” (DEI) academic elites at the Harvard Kennedy School attempts to justify the distribution of reparations now by claiming that the U.S. has a long history of paying out money to harmed individuals. From the paper’s abstract:

[T]he United States has a long-standing social norm that if an individual or community has suffered a harm, it is considered right for the federal government to provide some measure of what we term “reparatory compensation.” In discussing this norm and its implications for Black American reparations, we first describe the scale, categories, and interlocking and compounding effects of discriminatory harms by introducing a taxonomy of illustrative racial harms from slavery to the present. We then reveal how the social norm, precedent, and federal programs operate to provide victims with reparatory compensation, reviewing federal programs that offer compensation, such as environmental disasters, market failures, and vaccine injuries. We conclude that the government already has the norm, precedent, expertise, and resources to provide reparations to Black Americans. [emphasis mine]

The highlighted word is key to understanding the fundamental intellectual dishonesty of these incompetent Harvard academics. In their paper they use numerous examples of cases where the government has provided compensation to actual individuals — such as veterans, individuals harmed by radiation from nuclear tests, and those who lost their pensions due to bankruptcy or mismanagement of their pension funds — and then claim this proves paying reparations to the community of blacks, based merely on their race and the past existence of slavery, is within traditional American jurisprudence.

This is all a lie. » Read more

Are Chang’e-6’s lunar samples on the way back to Earth?

9:30 am

In Friday’s June 21, 2024 quick links, changes to lunar orbit of China’s Chang’e-6 sample return spacecraft were detected by ham operators. As I noted, “It isn’t clear whether this was the previous orbit adjustment, a new one, or the burn that would send the sample return capsule back to Earth.”

According to Space News today, the spacecraft with the samples is on its way back to Earth, based on additional information detected by amateurs. China however has released no information on the status of the spacecraft.

Upon return to Earth, the reentry capsule is expected to touch down at Siziwang Banner, Inner Mongolia during an half-an-hour long window opening at 1:41 a.m. Eastern (0541 UTC) June 25. The information is according to airspace closure notices. CNSA has not openly published timings of mission events in advance.

Earlier reports (which I can’t find now) had said the return was tentatively scheduled for June 25, 2024, so this Space News report makes sense. The lack of information from China is par for the course.

France’s CNES space agency begins work adapting commercial launchpad at French Guiana for specific startup rocket companies

9:15 am

Capitalism in space: France’s CNES space agency, which has taken back ownership of its French Guiana spaceport from Arianespace, has now begun adapting its new commercial launchpad there for a number of specific startup rocket companies.

In early 2021, the French space agency CNES announced plans to open up the Guiana Space Centre to commercial micro and mini-launch operators. The agency explained that it would be developing a multi-user launch pad on the grounds of the old Diamant launch complex. In July 2022, CNES announced that it had pre-selected Avio, HyImpulse, Isar Aerospace, MaiaSpace, PLD Space, Rocket Factory Augsburg, and Latitude to utilize the new launch complex.

During a media briefing following ESA’s 327th council meeting, Tolker-Nielsen explained that “general work” on the complex had already started and that work on “specific adaptations” was about to begin. These specific adaptations will be completed by the companies that will utilize the launch complex to ensure it fulfills the specific needs of their launch systems.

Of the seven rocket startups listed above, Tolker-Nielson said PLD was the ahead of the others in adapting the pad for its use, though no launch date is set. Avio meanwhile will likely not have to use this pad, as it owns the Vega family of rockets, which have already launched from French Guiana using another launchpad.

China’s successfully completes full 10K hop of 3-engine launch test rocket

8:57 am

China’s yesterday successfully completed a 10K hop lasting six minutes of 3-engine launch test small-scale rocket, lifting off from its Jiuquan spaceport in northwest China.

Developed by the Shanghai Academy of Spaceflight Technology, the carrier rocket features a 3.8-meter diameter rocket body, powered by three 70-tonne LOX/Methane engines and equipped with a full-size landing buffer system.

The rocket achieved vertical soft landing at a fixed point through take-off, ascent and variable-thrust descent. The test fully verified the rocket’s VTOL configuration, heavy-load landing buffer technology, reusable propulsion technology with high and strong variable thrust, and high-precision landing navigation and control technology.

I have embedded below a video that shows the take-off, parts of the flight, and landing. China hopes to fly a full scale orbital version, with a 4-meter diameter, in 2025.

Spacewalk on ISS canceled due to spacesuit issue

8:48 am

Two astronauts on ISS were forced today to abort their spacewalk soon after opening the hatch to go outside because a water issue in one suit.

This is the second time this spacewalk has been aborted. The first time, on June 13, 2024, was canceled due to an unspecified “spacesuit discomfort issue.”

This cancellation might cause a problem with the presently unscheduled return of Starliner, as its June 26, 2024 return was postponed to allow this spacewalk to take place without any schedule conflicts. Or it might simplify Starliner’s return, as the spacewalk will not happen due to spacesuit issues.

Note also that the American suits are old, and prone to these kinds of water leak issues. NASA started a project to replace them fifteen years ago, spent more than a billion on designs, getting nothing built, before abandoning its effort and awarding the project to two private companies.

India’s prototype X-37B, dubbed Pushpak, completes third successfully drop test runway landing

10:43 pm

India’s space agency ISRO today successfully completed the third drop test from a helicopter to a runway landing of an X-37B engineering test vehicle, dubbed Pushpak.

The winged vehicle, named ‘Pushpak’, was released from an Indian Air Force Chinook Helicopter at an altitude of 4.5 km. Pushpak autonomously executed cross-range correction manoeuvres, approached the runway, and performed a precise horizontal landing at the runway centerline.

The vehicle also used the same body and flight systems from the previous flight without modifications. Though this is hardly a return from space, the landing profile attempted to duplicate much of that flight path, and thus demonstrated ISRO engineers are on the right track for creating a reusable mini-shuttle.

SpaceX completes two launches today, from opposite coasts

10:37 pm

The bunny marches on! SpaceX successfully completed two launches today.

First, its Falcon 9 rocket launched 22 Starlink satellites from Cape Canaveral in Florida. This was the launch that had been delayed several times by weather, and then by a tecnical launch abort at T-0. After several days of review, it lifted in the morning today with no problems, the first stage completing its eleventh flight, landing on a drone ship in the Atlantic.

Then, about ten hours later a Falcon 9 rocket lifted off in the evening Vandenberg in California, putting 20 Starlink satellites into orbit, 13 of which are said to be designed for direct cell-to-satellite capabilities. This first stage also completed its eleventh flight, landing on a drone ship in the Pacific.

This post is a bit late because we had a five hour power outage in my neighborhood tonight, caused apparently when someone drove into a utility pole and knocked it over.

The leaders in the 2024 launch race:

66 SpaceX
28 China
8 Russia
8 Rocket Lab

American private enterprise now leads the world combined in successful launches, 77 to 42, while SpaceX by itself still leads the entire world, including other American companies, 66 to 53.

China launches gamma-ray space telescope

9:50 am

China today successfully launched the Space-based Multi-band Variable Object Monitor (SVOM) gamma-ray space telescope, a 20-year-long joint Chinese-French project to monitor astronomical gamma ray bursts.

SVOM was placed in orbit by a Long March 2C rocket lifting off from China’s Xichang spaceport in the southwest of China. No word on where the rocket’s lower stages — which use very toxic hypergolic fuels — crashed inside China. UPDATE: See this video from China. Apparently one stage landed close to homes, spewing that orange hypergolic fuel.

The leaders in the 2024 launch race:

64 SpaceX
28 China
8 Russia
8 Rocket Lab

American private enterprise still leads the world combined in successful launches, 75 to 42, while SpaceX by itself still leads the entire world, including other American companies, 64 to 53.
