China launches “remote-sensing satellites” test satellites

8:51 am

China today successfully placed a classified “group” of “remote-sensing satellites” into orbit to test “new technologies of low-orbit constellations,” its Long March 4B lifting off from the Xichang spaceport in the southwest of China.

That is all the information that China’s state-run press released. No word was released as to where
in China the lower stages crashed. As to the number of satellites launched, according to this independent site, the launch had nine payloads, which suggests but does not confirm nine satellites.

The leaders in the 2024 launch race:

86 SpaceX
37 China
10 Rocket Lab
9 Russia

American private enterprise still leads the rest of the world combined in successful launches 101 to 55, while SpaceX by itself leads the entire world, including American companies 86 to 70.

Chinese pseudo-company launches six satellites from off-shore barge

9:12 am

The Chinese pseudo-company Galactic Energy today completed a launch of six satellites, its Ceres-1 rocket lifting off from a barge off the coast of northeast China.

China’s state-run press once again illustrated how fake these pseudo companies are, in that it made no mention of the company in its official report, stating simply that the launch was completed by “China.” The companies might raise investment capital funds and sign contracts and make profits, but in the end they only do what they are told to do by the Chinese communists, and at any point those communists can confiscate the company for the government’s own purposes.

The leaders in the 2024 launch race:

Chinese scientists find method to extract water from Chang’e-5 lunar samples

12:04 pm

Proposed concept for extracting water from lunar regoilth
Proposed concept for extracting water from
lunar regoilth

Chinese scientists have found that by heating Chang’e-5 lunar samples to 1,700 degrees Fahrenheit it is possible to extract a significant amount of water. From the paper’s abstract:

FeO and Fe2O3 are lunar minerals containing Fe oxides. Hydrogen (H) retained in lunar minerals from the solar wind can be used to produce water. The results of this study reveal that 51–76 mg of H2O can be generated from 1 g of LR [lunar regolith] after melting at temperatures above 1200 K. This amount is ∼10,000 times the naturally occurring hydroxyl (OH) and H2O on the Moon. … Our findings suggest that the hydrogen retained in LR is a significant resource for obtaining H2O on the Moon, which are helpful for establishing scientific research station on the Moon.

A video in Chinese (hat tip BtB’s stringer Jay) that describes this research can be found here. (If any of my readers understands Chinese and can provide a translation of this video’s narration, I would be very grateful.) It includes an artist’s rendering (screen capture to the right) showing how such a system on the Moon could work to extract water from the soil. Sunlight would be focused by a lensed mirror into a glass-domed container, heating the ground. The water would evaporate, condense on the glass and be sucked into a tube that would transfer it to a water tank.

This design is of course very simple and preliminary. According to Jay, “They need to heat the soil to 1000℃ (1832°F) to get the iron oxide in the lunar soil to split, the oxygen combines with hydrogen to make water and iron (melting point of iron is about 1500℃). You will need a nuclear reactor to produce that much power for an inductive furnace to get that hot. Doing the calculation, it would take about 245kw to heat up a metric ton of dirt in one hour to a 1000℃ degrees. It could be done slower over 24 hours at 10kw.”

Despite the technical difficulties getting such equipment operational on the Moon, that this research suggests water can be produced practically anywhere on the lunar surface is signficant. It suggests that even if no easily accessible water ice is found in the permanently shadowed craters at the poles, lunar bases still have viable options for obtaining water, and they don’t have even be at the poles.

China launches new set of classified remote-sensing satellites

9:06 am

China today launched a new set of classified remote-sensing satellites supposedly designed to test “new technologies of low-orbit constellations, using its Long March 4B rocket lifting off from its Xichang spaceport in the southwest of China.

Almost no information was released about the satellites. Nor did China’s state-run press reveal where the rocket’s lower stages, carrying toxic hypergolic fuels, crashed within China.

The leaders in the 2024 launch race:

81 SpaceX
34 China
10 Rocket Lab
9 Russia

American private enterprise still leads the rest of the world combined in successful launches 96 to 52, while SpaceX by itself still leads the entire world combined, including American companies, 81 to 67.

These numbers will likely change in only a few hours, as SpaceX has another launch today, scheduled for 11:20 am (Pacific).

Chinese Long March 6A upper stage breaks up into debris shortly after deploying satellites

9:37 am

Ground and satellite reconnaissance data now indicates that the upper stage of the Chinese Long March 6A rocket that on August 6 launched the 18 satellites in a proposed Chinese 14,000 satellite internet constellation broke up into numerous pieces shortly after deploying the satellites.

The detection was made by the company Slingshot Aerospace, which tracks orbital spacecraft looking for the appearance of this kind of space junk.

This is actually the second time recently that an upper stage of a Long March 6A has broken up shortly after launch. In December 2022 the same thing was detected following a November launch.

All told, this relatively new Chinese rocket has launched seven times, and has had its upper stage break up twice. Apparently, China not only doesn’t care if the lower stages of its many rockets crash on top of its own citizens, it is quite okay with littering near-earth orbital space with debris. It needs to fix the upper stage of this rocket now, so such break-ups no longer occur.

China launches first 18 satellites in a new Starlink-type internet constellation

11:52 pm

China today launched the first 18 satellites in a new Starlink-type internet constellation dubbed Spacesail, its Long March 6A rocket lifting off from the Taiyuan spaceport in north China.

No word on where the rocket’s lower stage and four strap-on boosters landed within China. Jay notes that this Chinese constellation is now ahead of Blue Origin’s Kuiper constellation, a pattern that sadly has been repeated over and over again.

Chinese scientists discover thin-layered graphene in Chang’e-5 lunar samples

9:47 am

Chinese scientists analyzing one of the lunar samples brought back in 2021 by Chang’e-5 from the Moon’s near side have detected for the first time what they call “natural few-layered graphene.”

You can read the paper here. The samples from Chang’e-5 came from some of what are believed are some of the youngest lava on the Moon. This discovery confirms that conclusion. From the paper:

The identification of graphene in the core–shell structure suggests a bottom-up synthesis process rather than exfoliation, which generally involves a high-temperature catalytic reaction. Therefore, a formation mechanism of few-layer graphene and graphitic carbon is proposed here.

Volcanic eruption, a typical high-temperature process, occurred on the Moon. Lunar soil can be stirred up by solar wind and high-temperature plasma discharge can be generated on the Moon’s surface. … [T]he Fe-bearing mineral particles, such as olivine and pyroxene, in lunar soil might catalyse the conversion of carbon-containing gas molecules in the solar wind or polycyclic aromatic hydrocarbons into graphitic carbon of different thicknesses and morphologies on their surfaces, including few-layer graphene flakes and carbon shells.

These graphene flakes are likely to disappear over time, so its existence reinforces the belief that this lava is young.

Unlike too many American planetary scientists recently — who have repeatedly implied that finding anything even remotely related to life processes suggests the possibility of life on Venus and Mars — the Chinese scientists don’t make the additional absurd claim that finding carbon on the Moon suggests the existence of life. It doesn’t. Kudos to them for being good scientists.

As a result, expect American mainstream media to pay no attention to this result, despite its intriguing and unprecedented nature.

China launches “high-orbit internet satellite”

8:45 am

China last night successfully launched what its state-run press merely labels as a “high-orbit internet satellite”, its Long March 3B rocket lifting off from its Xichange spaceport in southwest China.

No word on where the rocket’s lower stage and strap-on boosters, using very toxic hypergolic fuels, crashed inside China. Previous launches have had those booster crash near habitable area.

China scientists propose both a communications and GPS-type infrastructure on the Moon

9:34 am

In line with the remarkably rational and long term plans China has developed for exploring the solar system, Chinese scientists have proposed the country develop both a communications and GPS-type infrastructure on the Moon, with both including constellations of satellites in orbit as well as facilities on the ground.

A first phase would establish satellites in elliptical frozen orbits around the moon. A second phase would see further … satellites and spacecraft at Earth-moon Lagrange points 1, 2, 4 and 5, a near-rectilinear halo orbit (NRHO), and a spacecraft in geostationary orbit, termed a cislunar space station.

A third and final phase would add satellites in existing and new distant retrograde orbits (DRO), forming a near-moon space and extended space constellations. The system also includes comprehensive ground-based facilities.

While this plan is simply a proposal, it fits with China’s overall strategies for lunar exploration, all of which are designed carefully so that they can be scaled up for more complex operations there as well as elsewhere in the solar system. And based on China’s track record in space in the past decade, we should be entirely confident this program or some variation will be built.

That is, unless China undergoes a major economic collapse and a change in leadership that has different priorities.

Scientists find hydrogen molecules in Chang’e-5 lunar samples

9:18 am

According to China’s state-run press, scientists analyzing the lunar samples brought back by its Chang’e-5 lander have detected extensive “hydrated” molecules in Moon’s regolith.

The mineral’s structure and composition bear a striking resemblance to a mineral found near volcanoes on Earth. At the same time, terrestrial contamination or rocket exhaust has been ruled out as the origin of this hydrate, according to the study.

The Chinese article keeps referring to these molecules as a form of “water molecules” but that is dead wrong. These are mineral molecules that simply have hydrogen as a component. There is no water here.

The discovery suggests that the detection of hydrogen on the surface of the Moon, both in the permanently-shadowed craters at the poles as well as lower latitudes, might not be water at all, but hydrated minerals. If so, the Moon is going to be a much more difficult place to establish colonies or even research bases, as getting water (and hydrogen and oxygen) is going to require a much more difficult mining and processing effort.

For several years the data has increasingly pointed in this direction. And for several years I have noticed a strong unwillingness of scientists and the press to recognize the trend (as illustrated by the above article’s false insistence that these are water molecules). Water ice has not been ruled out yet in the permanently-shadowed craters at the poles, but the evidence is mounting against it.

I suspect this reluctance is fueled by a desire to not say anything that might discourage exploration of the Moon, and the possibility of water there has been the main driver for all the recent lunar exploration programs. I can’t play that game. As much as I want humanity to explore the Moon and the solar system, we mustn’t do it based on lies. The facts need to be reported coldly.
