Launches by China and Russia

9:16 am

Earlier today both China and Russia successfully completed launches.

First, China launched a Chinese-built Pakistani communications satellite into orbit, its Long March 3B rocket lifting off from its Xichang spaceport from the southwest of China.

No real information was released about the satellite, or the fate of the rocket’s lower stages and four strap-on boosters, all of which use toxic hypergolic fuels and certainly crashed somewhere in China.

Next, Russia successfully launched a new Progress cargo ship to ISS, its Soyuz-2 rocket lifting off from Baikonur in Kazakhstan. The freighter will dock with ISS tomorrow. I have embedded video of the launch below, cued to T-30 seconds.

The rocket’s flight path took it over Kazakstan, Russia, and China, with drop zones for the lower stages in the first two. No word on whether the lower stages and four strap-on boosters crashed near habitable areas.

The leaders in the 2024 launch race:

57 SpaceX
25 China
8 Russia
6 Rocket Lab

American private enterprise still leads the world combined in successful launches, 65 to 39, while SpaceX by itself leads the entire world, including other American companies, 57 to 47.

Chang’e-6 to attempt landing on Moon’s far side on June 1st

9:42 am

Chang'e-6 landing zone

After spending almost a month in lunar orbit, the lander on China’s Chang’e-6 sample return mission will attempt a soft touchdown on Moon’s far side on June 1, 2024 at 8:00 pm (Eastern).

If successful, the lander will go through initial checks and setup. It will then begin drilling and scooping up materials from the surface. These samples, expected to weigh up to 2,000 grams, will be loaded into an ascent vehicle. The ascender will then launch the precious cargo back into lunar orbit for rendezvous and docking with the orbiter. Surface operations will last about 48 hours.

The map to the right indicates the landing zone by the red box, on the southern edge of Apollo Crater, indicated by the wavy white circle. The black circle marks the perimeter of South Aitken Basin, the largest impact basin on the Moon.

Once the ascender docks with the orbiter, the sample will be transferred into the sample return capsule, which will bring that sample back to Earth in late June.

China launches four satellites from sea platform

8:45 am

China's spaceports

The Chinese pseudo-company Galactic Energy today launched four satellites, its Ceres-1 rocket lifting off from its sea platform stationed off the coast of Shandong province, as shown on the map to the right.

As is usual now for China’s state-run press, the news report made no mention of the company, though unlike previous reports it did mention that the rocket was “commercial.” Since it does nothing without the full permission of the Chinese government, however, this is not a real independent company, with full ownership of its rocket. At any time the communists who run China can grab it for their own uses.

Chinese pseudo-company files plans for 10,000 satellite constellation

9:39 am

A Chinese pseudo-company has now filed plans for launching a 10,000 satellite constellation, the third such Chinese constellation planned.

A Chinese firm linked to commercial rocket maker Landspace has filed a notification with the ITU for a constellation comprising 10,000 satellites. Shanghai Lanjian Hongqing Technology Company, also known as Hongqing Technology, filed an Advance Publication Information (API) with the International Telecommunication Union (ITU) May 24. The filing outlines plans for a constellation named Honghu-3. It is to total 10,000 satellites across 160 orbital planes.

…The Honghu constellation plan appears to be the third 10,000-plus satellite megaconstellation planned by Chinese entities. It follows the national Guowang plan and the Shanghai-backed G60 Starlink proposal, both of which have been approved by China’s National Development and Reform Commission (NDRC). First batches of satellites for the pair are expected to launch in the coming months.

This new plan will likely not start launching satellites before 2025. Nonetheless, with these three large Chinese constellations plus both Starlink and Amazon’s Kuiper constellation, low Earth orbit is going to begin to get very crowded.

China’s X-37B releases object in orbit

8:55 am

China’s copy of the U.S.’s military’s X-37B reusable mini-shuttle, dubbed Shenlong apparently released an object during its ongoing third orbital mission.

A new object (59884/2023-195G) has been cataloged associated with the Chinese CSSHQ spaceplane in a 602 x 608 km x 50.0 deg orbit. It seems to have been ejected about 1900 UTC May 24.

It is possibly this object is to test recapture maneuvers, as was done by during the mini-shuttle’s previous flight. It is also possible this release is preliminary to the end of the mission and the return of Shenlong to Earth. It is also possible it has a completely different purpose, since China has released practically no information about this spaceplane or any of its missions.

The present mission began a little more than seven months ago, releasing six small satellites a few days after launch. The previous two lasted two days and 276 days respectively. As with everything else, we have no idea how much longer it will remain in orbit.

China’s Kuaizhou-11 rocket launches four satellites

9:37 am

China yesterday successfully placed four satellites into orbit, its solid-fueled Kuaizhou-11 rocket lifting off from its Jiuquan spaceport in northwest China.

The only information about the satellites released by China’s state-run press was that one was “an ultra-low orbit technology test satellite,” likely similar to the reconnaissance satellites that Redwire is producing here in the U.S.

The state-run press also made no mention on where the rocket’s lower stages crashed inside China.

Significant water found in samples from China’s Chang’e-5 Moon mission

12:33 pm

According to a new paper published in late April, scientists analyzing the samples returned from the Moon by China’s Chang’e-5 Moon mission in 2021 have found more water embedded in the topsoil than expected. From the paper’s conclusions:

[O]ur results indicate that a considerable [solar wind]-derived water is stored within at least the uppermost meter (down to 0.8 meters) of the regolith beneath the lunar surface. This type of water represents a valuable potential resource for future in situ exploration of the Moon, as it not only has higher contents than indigenous water (up to several wt.% vs. <50 ppm) but could also be extracted by heating.

We are still not talking about a lot of water, but this result suggests there is more than earlier reports from Chang’e-5’s samples. This result also could explain the hydrogen signature across much of the Moon’s surface by Chandrayaan-1.

Serbia joins China’s lunar base project

12:21 pm

Serbia this week signed an agreement with China to become the eleventh nation to join its International Lunar Research Station (ILRS) lunar base project.

China’s project now has eleven partner nations (Azerbaijan, Belarus, Egypt, Nicaragua, Pakistan, Russia, Serbia, South Africa, Thailand, Turkey, and Venezuela) and eleven academic or governmental bureaucracies.

Except for China and Russia, the other partners are very minor players in space, and will likely contribute relatively little to the lunar base other than providing China some shallow positive PR.

Nonetheless, the two competing alliances in settling the solar system are becoming clear. On one side you have the alliance led by the U.S. under the Artemis Accords, while on the other you have an alliance led by China, under its lunar base project. Both right now appear only interested in establishing government power in space.

In the middle will be ordinary people, dreaming of building new societies to live in on other worlds. Sadly it increasingly appears they will be crushed between these two big government alliances. Though the U.S. alliance was initially established to foster private property and ownership so that those settlers could have as free and as prosperous a life as the Americans who settled the United States, it no longer seems interested in that goal.

China launches earth observation satellite

9:02 pm

China this evening (May 9th in China) successfully launched an earth observation satellite into orbit, its Long March 3B rocket lifting off from its Xichang spaceport in the southwest of China.

No word on where the first stage crashed in China, though there was a report in the Philippines that an upper stage landed near Rozul Reef and Patag Island in the West Philippine Sea. All the stages use toxic hypergolic fuels.

Chang’e-6 enters lunar orbit

9:42 am

Chang'e-6 landing zone

China’s Chang’e-6 sample return spacecraft successfully entered lunar orbit today, in preparation for its mission to land and bring back material from the the far side of the Moon. The landing zone is indicated by the red box on the map to the right, on the southern rim of Apollo Crater in the southern hemisphere. That crater is inside South Aitkin Basin, one the Moon’s largest impact basins.

The spacecraft will next adjust its orbit to prepare for sending its lander-ascender sections down to the surface. If the landing goes well, it will drill into the surface, place some material into the ascender section, which will then lift-off and dock with the orbiter-return section in orbit. The material will be transferred into the return section, which will separate and bring the material back to Earth, sometime in late June.

China successfully completes first launch of new Long March 6C rocket

9:33 am

China today successfully completed the first launch of its new Long March 6C rocket, lifting off from its Taiyuan spaceport in the north interior of China.

The rocket uses kerosene as its fuel, rather than the toxic hypergolic fuels used in its older rockets, and is part of an effort to replace all those older rockets. Thus, when its lower stage crashes inside China, the risks of it harming anyone is reduced somewhat. China released no information on where that first stage crashed on this first launch.

The rocket placed four satellites in orbit.

China launches Chang’e-6 sample return mission to the far side of the Moon

9:17 am

Chang'e-6 landing zone

The new colonial movement: China today successfully launched its Chang’e-6 sample return mission to the far side of the Moon, its Long March 5 rocket lifting off from its coastal Wenchang spaceport. Unlike the Long March 5B, whose core stage reaches an unstable orbit and later crashes uncontrolled somewhere on Earth, the core stage of Long March 5 does not, and thus returns to Earth immediately, over the ocean.

The graphic from the right, released by China’s state-run press, shows the landing zone in red on the far side. The target is the southern rim area of Apollo Crater, marked by the uneven white outline. Apollo sits inside the South Aitken Basin, one of the Moon’s largest impact basins, 1,600 miles across, and roughly indicated by the black circle. The circle to the left of Apollo indicates Van Karman crater, where Chang’e-4 landed in 2019 with the Yutu-2 rover, both still operating.

The mission includes a lunar orbiter, a lander, an ascent vehicle, and an Earth sample return capsule. If all goes as planned, the samples will return to Earth in 53 days.

Scientists: computer modeling suggests one lunar crater is the origin of a nearby asteroid

11:02 am

The uncertainty of science: Using computer modeling some scientists now suggest that the nearby asteroid 2016 HO3, also known as Kamo’oalewa, that has a solar orbit that periodically flips around the Earth, came from an impact a million years ago that created the Giordano Bruno crater on the moon’s far side.

According to the simulations, it would have required an impactor of at least 1 kilometer (0.6 mile) in diameter to launch a large fragment like Kamo’oalewa beyond the moon’s gravitational pull. According to the group’s model, the impact would have dug up Kamo’oalewa from deep beneath the moon’s surface, leaving behind an impact crater larger than 10 to 20 kilometers (6-12 miles) in diameter. Additionally, the crater would have to be younger than the average lifetime for near-Earth objects, which spans about 10 million to 100 million years, a very short and recent period in the history of the solar system.

While the lunar surface is riddled with thousands of craters from impacts spanning the moon’s 4.5 billion year-history, only Giordano Bruno with its 14-mile diameter and estimated 4 million years of age fits the bill in terms of size and age, making it the most probable source of Kamo’oalewa’s origin. The team also showed that this scenario is feasible from an impact dynamics perspective.

To say that this conclusion is uncertain is an understatement of monumental proportions. However, the possibility is real. A Chinese asteroid mission, dubbed Tianwen-2, will likely found out, as it is planning to bring samples back from this asteroid by 2027.

No word on where the four strap-on boosters, the payload fairing, the core stages, and the upper stage crashed inside China, using very toxic hypergolic fuels. This new crew will replace the present crew, who are completing a six-month tour. The new crew will complete a similar-length mission.

China reveals its rough plans for building its manned moon base.

9:35 am

At a conference in China this week, the chief designer of China’s lunar exploration program, Wu Weiren, outlined roughly the plans for building China’s International Lunar Research Station (ILRS) on the Moon.

According to Wu, the first phase of the ILRS construction project will see a basic station built by 2035 in the lunar south pole region. This basic station will have comprehensive scientific facilities with complete basic functions and supporting elements to carry out regular scientific experiments, and develop and utilize resources on a limited scale.

The second phase will see expansion of the station, set for completion by 2045, with a moon-orbiting space station as the hub and facilities featuring complete functions, considerable scale and stable operation. It will carry out comprehensive lunar-based scientific research and resource development and utilization, and conduct technical verification as well as scientific experiments and research for a manned landing on Mars.

This schedule contradicts other recent government statements that suggested the first phrase would be completed by 2030. Either way, we now have a rough timeline which, based on China’s past announcements, should be a reasonably accurate measure of what it now plans to do.

The timeline however is very long, and many other events outside of this program, such as war with Taiwan or sudden changes in the leadership of the ruling communist party, could change it drastically.

China releases new geological atlas of the Moon

9:03 am

China's geologic map of the Moon

The map above is one low resolution example of a new detailed geological atlas that Chinese scientists have created and just released, using data obtained from all of China’s recent lunar missions, both orbiters and landers.

More information here.

The Chinese Academy of Sciences (CAS) has released the highest-resolution geological maps of the Moon yet. The Geologic Atlas of the Lunar Globe, which took more than 100 researchers over a decade to compile, reveals a total of 12,341 craters, 81 basins and 17 rock types, along with other basic geological information about the lunar surface. The maps were made at the unprecedented scale of 1:2,500,000.

…The CAS also released a book called Map Quadrangles of the Geologic Atlas of the Moon, comprising 30 sector diagrams which together form a visualization of the whole Moon.

The map has been released in both Chinese and English.

More partners join China’s International Lunar Research Station

9:18 am

China today announced the addition of three more international partners in its project to build a permanent base on the Moon, dubbed the International Lunar Research Station (ILRS).

The new partners of the ILRS include Nicaragua, the Asia-Pacific Space Cooperation Organization and the Arab Union for Astronomy and Space Sciences. China will collaborate with these three parties on various issues concerning the ILRS, including its demonstration, engineering implementation, operation and application, according to the CNSA.

China’s project now has ten partner nations (Azerbaijan, Belarus, Egypt, Nicaragua, Pakistan, Russia, South Africa, Thailand, Turkey, and Venezuela) and eleven academic or governmental bureaucracies.

If all goes as planned, China hopes to have the basic station established by 2030, which it will periodcially and intermittently send astronauts.

Hubble celebrates 34 years in orbit with a new photo of the Little Dumbbell Nebula

9:53 am

The Little Dumbbell Nebula
Click for original image.

Cool image time! To celebrate the 34th anniversay of its launch in 1990, astronomers have used the Hubble Space Telescope to take a new photo of the Little Dumbbell Nebula (also known as M76), located about 3,400 light years away and one of the most well-known planetary nebulae in the sky.

That picture is to the right, cropped, reduced, and sharpened to post here. From the caption:

M76 is composed of a ring, seen edge-on as the central bar structure, and two lobes on either opening of the ring. Before the star burned out, it ejected the ring of gas and dust. The ring was probably sculpted by the effects of the star that once had a binary companion star. This sloughed off material created a thick disk of dust and gas along the plane of the companion’s orbit. The hypothetical companion star isn’t seen in the Hubble image, and so it could have been later swallowed by the central star. The disk would be forensic evidence for that stellar cannibalism.

The primary star is collapsing to form a white dwarf. It is one of the hottest stellar remnants known at a scorching 250,000 degrees Fahrenheit, 24 times our Sun’s surface temperature. 
The sizzling white dwarf can be seen as a pinpoint in the center of the nebula. A star visible in projection beneath it is not part of the nebula.



Pinched off by the disk, two lobes of hot gas are escaping from the top and bottom of the “belt,” along the star’s rotation axis that is perpendicular to the disk. They are being propelled by the hurricane-like outflow of material from the dying star, tearing across space at two million miles per hour.

Since launch Hubble has made 1.6 million observations of over 53,000 astronomical objects, and continues to be in high demand by astronomers, with only one request in six able to get time on the telescope. Not surprisingly, almost all of Hubble’s biggest discoveries were unexpected. Its future right now rests with its last three working gyroscopes used to orient it precisely. When one more fails, it will go to one-gyro mode, which will limit the precision of that orientation significantly. At that point the sharpness of the telescope’s imagery will sadly decline.

The only comparable orbital optical telescope now planned is China’s Xuntian optical telescope, scheduled for launch next year. It will fly in formation with the Tiangong-3 space station, allowing astronauts to periodically do maintenance missions to it. As I noted many times previously, American astronomers better start learning Chinese, assuming China even allows them access. Nor will these American astronomers have a right to complain, as it was their decision to not build a Hubble replacement, in their 2000, 2010, and 2020 decadal reports.

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.

Turkey to join China’s lunar base program

9:02 am

Turkey yesterday announced that it is applying to join China’s program to build a lunar base on the Moon, dubbed the International Lunar Research Station (ILRS), becoming the ninth nation in that partnership.

Those nations are Azerbaijan, Belarus, Egypt, Pakistan, Russia, South Africa, Thailand, Turkey, and Venezuela. In addition, another nine academic organizations of one kind or another have signed on.

Interestingly, Turkey’s government apparently decided to partner with China after it flew its own astronaut on Axiom’s AX-3 mission to ISS in January, flying in a SpaceX Dragon capsule launched by SpaceX’s Falcon 9. Previously it had also signed a deal with Sierra Space to participate in both its Dream Chaser and Orbital Reef station.

This new agreement suggests the present instability of international politics has forced it to go to its very powerful neighbors. Or maybe Turkey is signing on with everyone, attempting to burn the candle at both ends.

Argentina demands right to inspect Chinese antenna facility

9:45 pm

The Argentina government of Javier Milei is now demanding the right to inspect a Chinese antenna facility that was established in Argentina in 2014 and began operating in 2017 under a 50-year-lease.

Under the agreement between the two nations, 10% “of the resources in the base must be utilized by Argentina.” However, China has been operating the facility unsupervised from the beginning. Likely built to support China’s space program, manned and planetary, U.S. officials have also suggested it is being used for military purposes, a possibility that cannot be dismissed since all of China’s space program falls under the supervision of the People’s Liberation Army.

Milei apparently wants a hand in its operation, or at least a much clearer idea of what it is doing. It is very possible he will even shut it down if he is not satisfied with the answers he gets.

Except for Russia, the partners in China’s program are mostly there for public relations purposes, and will contribute little to the project. And Russia itself will likely not contribute much either, considering its inability to get any major new projects launched for the past two decades.

An abandoned module from one of China’s manned capsules burns up over California

9:29 am

The orbital module of China’s Shenzhou-15 manned capsule, launched with three astronauts in November 2022 and then abandoned in orbit when those astronauts returned to Earth in the spring of 2023, burned up over southern California yesterday.

The fall created a blazing fireball witnessed by people from the Sacramento area all the way down to San Diego, according to the American Meteor Society (AMS). As of Tuesday afternoon, 81 people had reported sightings of the event to the AMS.

It is unlikely, though not impossible, that any pieces hit the ground. The module is considered small enough to be destroyed during descent. Nonetheless, its uncontrolled re-entry highlights China’s general irresponsibility when it comes to space junk. For example, the Russia Soyuz capsule has a similar design, but based on history Russia has for decades routinely controlled the de-orbit of its abandoned orbital module so that it does not come down over land.

China working to save classifed lunar mission from launch failure

9:40 am

Orbital data now suggests that Chinese engineers are attempting to save a classifed lunar mission from the failure of its launch rocket to put the two satellites in their proper high orbit.

The small DRO-A and B spacecraft launched from Xichang spaceport on a Long March 2C rocket March 13. Hours later, the first acknowledgement of the mission came from Chinese state media Xinhua, which announced that the spacecraft had not been inserted accurately into their designated orbit by the rocket’s Yuanzheng-1S upper stage. “The upper stage encountered an abnormality during flight, causing the satellites to fail to accurately enter the preset orbit,” Xinhua stated. “Relevant disposal work is currently underway,” it added, citing Xichang launch center.

Data from the U.S. Space Force’s 18th Space Defense Squadron (SDS) initially showed objects associated with the launch in low Earth orbit (LEO). However, subsequent Two Line Element (TLE) data sets, a mathematical representation of a satellite’s mean orbit, from 18 SDS show an object from the launch (international designator 2024-048A) in a 525 x 132,577-kilometer, highly-elliptical, high Earth orbit. This has since been raised, with the spacecraft tracked in a 971 x 225,193-km orbit on March 26.

This indicates that at least one satellite, and perhaps both—if still attached to one another—separated from the upper stage, and that the object’s orbit has been raised.

It is very possible that further engine burns could put these satellites into lunar orbit, which would then save the mission and turn the March 13 launch failure into a success.

Why China is keeping this particular lunar mission so secret is another question, that still remains unanswered.
