SpaceX and Chinese pseudo-company complete launches

Two launches today. First, a new Chinese pseudo-company, dubbed Space Pioneer, completed the first launch of its liquid kerosene-fueled Tianlong-1 rocket, putting a military surveillance satellite into orbit.

Space Pioneer is the third Chinese pseudo-company to achieve orbit, but the first to do it with a liquid-fueled rocket. The previous two, Ispace and Galactic Energy, used solid-fueled rockets based on military missile technology. All of these Chinese companies follow a private model. An individual or a group of individuals creates the company, obtains private investment capital, and then wins contracts from the Chinese government. What makes them pseudo is that they do not work independently and freely, and really do not own their products. The Chinese government supervises and approves everything, and can take over at any time.

The second launch today was by SpaceX, using its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California to put a new smallsat constellation of ten military satellites, designed to test the quick development (under two years) of such smallsats for use by the military.

The first stage successfully completed its second flight, landing back at Vandenberg. The fairings completed their fourth and sixth flights, respectively.

The leaders in the 2023 launch race:

22 SpaceX
14 China
6 Russia
3 Rocket Lab

American private enterprise still leads China 25 to 14 in the national rankings, and the entire world combined 25 to 24. SpaceX by itself trails the entire world, including American companies, 22 to 27.

Two launches by China

China's spaceports
China’s spaceports

China yesterday and today successfully completed two launches using two different rockets from two different spaceports.

First, a Long March 2D rocket yesterday launched a set of four satellites establishing a new constellation of radar satellites designed to measure the Earth’s surface topography. Lift off was from the Taiyuan Satellite Launch Center in the northeast of China. No word on where the rocket’s first stage crashed.

Next, a Long March 4C rocket today placed in orbit a classified military “remote-sensing” satellite, lifting off from the Jiuquan Satellite Launch Center in China’s northwest. Once again, no information was released on where the first and second stages of the rocket crashed to Earth.

The leaders in the 2023 launch race:

21 SpaceX
13 China
6 Russia
3 Rocket Lab

American private enterprise still leads China 24 to 13 in the national rankings, and the entire world combined 24 to 23. SpaceX now trails the entire world combined, including American companies, 26 to 21.

Zhurong: Small polygons on light curved dunes indicate regular atmospheric water interaction

Zhurong's full journey on Mars

A paper published this week in Geophysical Research Letters by the science team for China Zhurong Martian rover has revealed the discovery of small polygon cracks on the surface of the many curved light-colored small dunes found in the region where Zhurong landed, suggesting the possibility of relatively recent water activity between the atmosphere and the dune surfaces.

Those dunes, dubbed transverse aeolian ridges (TARs) by the science team, are the many light curves visible in the labeled Mars Reconnaissance mosaic to the right. The blue arrows indicate Zhurong’s path south from its landing spot at the top and ending near the bottom of the picture after traveling about 1,400 feet.

According to the paper, the TARs were formed by the prevailing winds over many eons, coming first from the north and then from the northwest. The edges of the ridges, being smaller, are pushed ahead quicker, thus creating the curved shape. The polygons were small, never larger than 4 inches in size, with five to six sides. The scientists theorize that they were formed when atmospheric water interacted with the dune crust, causing fractures “due to temperature/moisture changes or deliquescence/dehydration cycling of salts”. This process could be slow or fast, and could actually be occurring in relatively recent times, as the scientists say it requires only a little water in the atmosphere.

More likely however we are seeing evidence of water from the past, from tens of thousands to several million years ago.

Zhurong meanwhile remains in hibernation, and might never come out of that condition. Orbital images indicate that its solar panels are dust-covered, the result of the heavy winter dust storm season. The project team however is hopeful that with time and the arrival of Martian summer the dust will be blown off and they can reactivate the rover. This hope however entirely depends on the arrival of a dust devil acoss the top of Zhurong, a random event that cannot be predicted. With both the Spirit and Opportunity rovers, such events happened regularly, allowing those missions to last years instead of only 90 days. With InSight it never happened, and the lander died after two-plus years on Mars.

Zhurong’s future fate thus remains unknown, but not promising at this moment.

Scientists detect water inside lunar samples returned to Earth by Chang’e-5

Chinese scientists have found water molecules trapped within glass beads found within the lunar samples returned to Earth by the lunar lander Chang’e-5.

The team polished and analysed 117 glass beads which were scooped up by China’s Chang’e-5 spacecraft in December 2020 and brought back to Earth. The beads are formed by tiny meteorites that bombard the surface of the Moon, which lacks the protection of an atmosphere. The heat of the impact melts the surface material, which cools into round glass beads around the width of a strand of hair.

…The glass beads may make up around three to five percent of lunar soil, according to the study. A “back of the envelope” calculation suggested that there could be around a third of a trillion tonnes of water inside all the Moon’s glass beads, he added. And it only takes mild heat of around 100 degrees Celsius (210 Fahrenheit) to liberate the water from the beads, Anand said.

According to the paper, the water’s origin might be tied to the solar wind, and might have been implanted in the beads after their impact formation.

If this analysis is correct, it might explain the hydrogen signature found in large parts of the lunar surface, where it is believed water simply couldn’t exist. It also might explain why the first images inside permanently shadowed lunar craters show no obvious ice, only what appear to be ponds of dark dust. The dust might contain these beads, and thus explain the hydrogen signature detected there as well.

China’s Long March 11 rocket launches classified Earth observation satellite

China yesterday used its Long March 11 solid-fueled four-stage rocket to launch a classified Earth observation satellite into orbit.

The launch was from an interior spaceport, so the rocket’s lower stages crashed somewhere in China or Mongolia. No word on if they landed near habitable areas.

The 2023 launch race:

17 SpaceX
10 China
4 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise still leads China 18 to 10 in the national rankings, and the entire world combined 18 to 16. SpaceX alone is now tied with entire world, including the rest of the U.S., 17 to 17.

Chinese pseudo-commercial rocket industry gearing up to launch numerous times from interior spaceport

China's spaceports

Even as China is presently building a commercial launch facility at its Wenchang spaceport on the coast, at least four of China’s pseudo-commercial rocket companies are gearing up to launch numerous times from the Jiuquan Satellite Launch Center in the interior of China.

The link above shows the launch sites being built at Jiuquan by pseudo-companies Landspace, Expace, CAS Space, and Space Pioneer. The map to the right illustrates what these interior launches will mean. Since none of these pseudo-companies will be vertically landing their first stages — at least not for several years — it means that numerous first stages will be coming down in many areas in China and Mongolia, most of which will be uncontrolled descents.

Eventually the Wenchang launch facility on the coast will become available, but based on past Chinese actions, do not expect these pseudo-companies to end their operations at Jiuquan at that time. All are controlled by the Chinese government, which has made it very clear it really doesn’t care if first stages crash near habitable areas.

Russia and China launch satellites

Two launches today in Russia and China.

First China used its Long March 2C rocket to launch a “remote sensing satellite” into orbit. No other information about the satellite was released. Nor was any information about whether the rocket’s first stage landed near habitable areas.

Next Russia used its Proton rocket to launch a classified satellite, likely a military surveillance satellite, into orbit. Like China Russia launches from an interior spaceport, with its first stage falling “in Karaganda Region of Kazakhstan,” with the second stage landing in drop zones in Russia. Russia, which has been doing this regularly for more than a half century, has always done a good job either avoiding habitable areas with the first stage crash, or keeping such stories out of the international press.

The 2023 launch race:

16 SpaceX
9 China
4 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise still leads China 17 to 9 in the national rankings, and the entire world combined 17 to 15. SpaceX alone is now tied with the entire world, including all other American companies, 16 all.

China’s Long March 4C rocket launches two Earth observation satellites

China today used its Long March 4C rocket to launch two Earth observation satellites from one of its interior spaceports.

No word on whether the expendable first stage landed near habitable areas. In related news the upper stage of a Long March 2D rocket, launched in June 2022, burned up over Texas on March 8, 2023. Such upper stage uncontrolled de-orbits are not unusual, and the effort by this news outlet to make a big deal about it is just politics. Unlike the lower stages of China’s rockets that hit the ground right after launch, it is very unlikely any pieces reached the surface, and any that did were small and posed a small risk.

The 2023 launch race:

16 SpaceX
8 China
3 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise still leads China 17 to 8 in the national rankings, and the entire world combined 17 to 13. SpaceX alone still leads the entire world, including American companies, 16 to 14.

China places classified satellite into orbit using Long March 2C rocket

From one of its interior spaceports China today successfully launched a classified “remote sensing” satellite using its Long March 2C rocket.

No information about the payload was released by China, not even a satellite name. Nor was there any word on whether the expendable first stage landed near habitable areas.

The 2023 launch race:

12 SpaceX
7 China
3 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise still leads China 13 to 7 in the national rankings, and the entire world combined 13 to 12. SpaceX on its own is now tied with the entire world 12 to 12.

China’s Long March 3B rocket launches communications satellite

China today successfully used its Long March 3B rocket, launching from an interior spaceport, to place a satellite into orbit to provide “high-speed broadband access services for fixed terminals, vehicle/ship/airborne terminals.”

Little other information has been released, but that description sounds remarkably similar to what OneWeb’s satellite constellation does.

No word on whether the rocket’s lower stages crashed near habitable areas.

The 2023 launch race:

12 SpaceX
6 China
2 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise still leads China 13 to 6, and the entire world combined 13 to 10. SpaceX alone leads the entire world combined 12 to 10.

China’s continued silence about Zhurong suggests Mars rover is dead

Zhurong's ground-penetrating radar data
The data from Zhurong’s ground-penetrating radar instrument.

Overview map
Zhurong’s final location is somewhere in the blue circle.

China’s continued silence about Zhurong — which should have come out of hibernation sometime in late December-early January — suggests the Mars rover did not survive the Martian winter, which this year was also lengthened near the end by some additional dust storms.

Zhurong went into hibernation in May 2022, at the start of winter, with plans to awaken in December. Like the helicopter Ingenuity and the lander InSight, it depends on solar power, and had to contend with a very relatively severe winter dust season this Martian year.

Even though the Chinese press has loudly touted Tianwen-1’s first two years in Mars orbit, it has made little or no mention of Zhurong, a silence that is deafening.

The silence is also foolish, because China has nothing to be ashamed of concerning Zhurong. The mission was only supposed to operate for 90 days. Instead it lasted more than a year, traveling much farther than planned. Most important, the data from its radar instrument (shown above) showed that, at this location at 25 degrees north latitude, there is no underground ice to a depth of 260 feet. That data confirmed that the Martian equatorial regions below 30 degrees latitude are very dry, with any underground ice existing rarely if at all. The icy regions above 30 degrees latitude do not appear to extend much farther south than that latitude.

China releases data sets from Chang’e-4 lander

China today released another set of data from the instruments on the Chang’e-4 lander, which landed on the far side of the Moon on January 3, 2019, bringing with it China’s Yutu-2 rover.

The datasets include 3,991.1 MB of 803 data files obtained by the four scientific payloads on the Chang’e-4 lander and rover between December 26, 2021 and January 10, 2022.

The data was posted on the official website of the Lunar and Planetary Data Release System, though none of the press reports from multiple China’s state-run press sources include it. All are simply the same three paragraph story, word for word. That site however is here, though it is entirely in Chinese and the English pages fail to load.

China aiming to complete 80 launches in 2023

According to this Space.com article, China’s many pseudo-company rocket startups are hoping to complete a total of approximately 19 to 21 launches in 2023, which when combined with the 60-plus launches the government hopes to complete, will give China a total of approximately 80 launches in 2023, a new record.

The article provides a good review of all of the pseudo-companies hoping to launch in the next few years. This list includes the following:

  • Galactic Energy: 8 to 10 launches in ’23 with its Ceres-1 solid fueled rocket
  • Space Pioneer: The first launch of its liquid-fueled Tainlong-2 rocket
  • Exspace: 7 launches with its Kuaizhou-1A and larger Kuaizhou-11, both solid-fueled
  • Landspace: A second launch attempt of its liquid-fueled Zhuque-2 rocket after a launch failure in ’22
  • Orienspace: The first launch of its Gravity-1 solid fueled rocket
  • Rocket Pi: The first launch of its Darwin-1 liquid fueled rocket
  • Ispace: Unknown after three consecutive launch failures of its Hyperbola-1 solid-fueled rocket

The article also adds launches from two government “private” spinoffs, CAS Space, planning 3 launches of its PR-1solid fueled rocket, and China Rocket, planning at least one launch of its Jielong-3 solid fueled rocket. Though both are touted as private, they are both really separate divisions created by China’s space agency CASC, with their launch counts likely included in the government’s hope-for 60 launches.

The pseudo private companies are somewhat more independent as they were founded by private individuals. All appear to have obtained private Chinese capital — in addition to government funding — to fund their development. All however are also entirely supervised in all actions by the government. None could build anything without government approval, and all are depending on government rocket technology that can be withdrawn at any time. These pseudo companies don’t really own their rockets. Furthermore, while they are able to sell their products to other private entities, their market appears almost entirely confined to China.

China to build space ground stations in Antarctica

According to a report on China’s state-run press that has now been deleted, China plans to build satellite ground stations in Antarctica for use by its ocean-observation satellites.

Official space industry newspaper China Space News reported Feb. 2 that a subsidiary of the China Aerospace Science and Industry Corporation (CASIC), a giant state-owned defense and space contractor, won a bid to construct a ocean observation satellite ground system. The project is being overseen by the National Satellite Ocean Application Service (NSOAS) and is stated to be part of a long-term marine economic development plan.

Renders of the 43.95 million yuan ($6.52 million) project show four radome-covered antennas at Zhongshan in East Antarctica. It is unknown if these are new and additional to antennas already established at the base. The antennas will assist data acquisition from Chinese satellites that orbit in polar and near-polar orbits. Satellites in these orbits are visible near the poles multiple times a day, allowing more frequent opportunities for downlink than with stations at lower latitudes.

Such ground stations could of course do many other things, including aiding military satellite surveillance.

Classified Chinese test satellite releases second object in orbit

A classified Chinese test satellite, launched on January 8th, apparently released a second object into orbit on January 16th, suggesting the satellite might be doing robotic rendezvous and docking tests, similar to tests by an earlier classified satellite.

China’s Shijian 21 satellite, which launched in 2021, also reached GEO and released a satellite, which was then used for tests. Shijian 21 then proceeded to dock with the defunct Chinese navigation and positioning satellite Beidou-2 G2 and towed it away to an orbit out of the way of the active spacecraft in GEO.

China is clearly attempting to develop the same robotic servicing technologies that commercial companies in the west are beginning to fly.

Chinese company based in Hong Kong signs deal to build spaceport in Djibouti, Africa

Djibouti's location in Africa
Djibouti’s location is indicated in black.

The government of Djibouti, one of the smallest nations in Africa and located at the southern end of the Red Sea, has signed an agreement with a pseudo Chinese company, the Hong Kong Aerospace Technology Group, to build a major spaceport there.

According to the translated press release, the five year project will cost one billion dollars, include a lease for 30 years, and involve the construction of a port, highway, and electrical power distribution system.

As much as Hong Kong for more than two centuries has been a haven for private enterprise, it is now under the control of the communist Chinese, and they would not allow anyone from Hong Kong to make such a deal unless they were in full control.

Based on the map, there is almost no launch path out of Djibouti that will not cross another nation’s territory. Unless the Chinese plan to make all the first stages launched from this site reusable, they are going to dropping stages on a lot of people’s heads, without their permission. And they will be doing it to some places where war is often and continues to be the most frequently used negotiating tactic.

Hat tip to stringer Jay.

China completes two launches today

China today continued its normal fast pace of winter launches, launching twice from two different spaceports.

First, a Long March 2C rocket launched a communications satellite from the Xichang Satellite Launch Center in southwest Sichuan Province. Then, a Long March 2D rocket launched three classified technology test satellites from the Jiuquan Satellite Launch Center in northwest China.

As I noted in yesterday’s quick space links, the drop zones for both were in China. No word as yet on whether anything fell near habitable area.

At present the 2023 launch race consists entirely of China with four launches, and SpaceX with two.

China is planning 60-plus launches in 2023

According to an article today in China’s state-run press, China is planning 60-plus launches in 2023, matching approximately its launch rate in 2022.

The China Aerospace Science and Technology Corporation (CASC) is expected to have more than 50 launches, and other Chinese space enterprises will have more than 10 launches.

If this number is accurate, it suggests a slowdown in activity by the many pseudo-companies that the Chinese government has allowed to form to compete for government and commercial business. Two years ago it appeared that these companies were launching at a faster rate, even many of those launches were failures.

China’s Mars orbiter and rover in trouble

Yesterday we reported a tweet from Scott Tilley that suggested engineers were having trouble establishing a communications link with China’s Mars orbiter Tienwen-1.

Today it appears that communications with China’s rover Zhurong have also not resumed following its winter hibernation from May until December.

The Post independently confirmed with two sources on Thursday that the rover should have resumed running by now, but no contact has been established.

Though Zhurong’s solar panels can be tilted to kick dust from them, during hibernation this is apparently not possible. Because the winter dust season this year was especially bad (killing InSight for example), it is possible that Zhurong experienced the same fate.

Zhurong had a 90 day mission, and instead lasted a year. Moreover, tt was never expected to survive a Martian winter. The achievement thus remains grand.

As for the Tienwen-1 orbiter, it would be a much bigger failure if communications cannot be re-established. China without question expected this orbiter to operate for years, even functioning as a communications link for later landers/rovers. Its loss will force a revision of later plans.

China launches twice today to start its 2023 year

China today launched twice with two different rockets from two different spaceports.

First, a Long March 7 rocket took off from its coast Wenchang spaceport, placing three satellites into orbit. Few details were released about the satellites, other than they were being used for various tests of new technology.

Second, the Chinese pseudo-company Galactic Energy used its military-derived solid fueled Ceres-1 rocket to place five smallsats into orbit from China’s interior Jiuquan spaceport. Once again, little information was released about the satellites.

At this moment China leads SpaceX 2 to 1 in the 2023 launch race. However, there are three more U.S. launches planned for today. First Virgin Orbit hopes to finally launch from Cornwall. You can watch the broadcast here.

Then SpaceX has two launches from opposite coasts within an hour, first launching a batch of Starlink satellites from Vandenberg at 9:15 pm (Pacific), then following with a launch from Kennedy of a batch of OneWeb satellites.

China releases first update on status of Yutu-2 since September

Click for full image. The red flag marks the landing site.

China today released its first update since September on the status of its Yutu-2 rover on the far side of the Moon. The map on the right shows the rover’s travels through December 2022.

As of today the rover has traveled 4,774 feet total, and about 450 feet since September. The goal, as stated in April 2021, was to “move northwest toward the basalt distribution area located about 1.2 km away.” At the time the rover was only averaging about 100 feet travel per lunar day. According to these numbers, it picked up the pace in the past year, though it is unclear whether it has reached that goal.

Philippines issues warning about Chinese rocket debris from launch

Flight path of Long March 3B

UPDATE: A tweet from China shows that the strap-on boosters of this rocket crashed near homes in China, though no one was hurt.

Original post:
—————–
The Philippine government issued a statement yesterday warning the public about possible debris from the December 29th launch by China of its Long March 3B rocket.

The Philippine Space Agency (PhilSA) is recommending precautionary measures related to expected unburned debris from the Long March 3B rocket scheduled for launch today between 12:33 PM and 01:10 PM Philippine time from the Xichang Satellite Launch Center in Xichang, Sichuan Province, China. Upon confirmation of planned launch dates, PhilSA immediately issued an advisory to all relevant government agencies on the estimated drop zone area and proposed the issuance of appropriate warnings on air and marine access.

Based on the Notice to Airmen (NOTAM) issued by the Civil Aviation Administration of China (CAAC) to the Civil Aviation Authority of the Philippines (CAAP), expected unburned debris, such as the rocket boosters and payload fairing, is projected to fall within a drop zone area located within the vicinity of Recto bank, approximately 137 kilometers from Ayungin Shoal and 200 kilometers from Quezon, Palawan. The unburned debris is designed to be discarded as the rocket enters outer space. While not projected to fall on land features or inhabited areas within the Philippine territory, falling debris poses danger and potential risk to ships, aircraft, fishing boats, and other vessels that will pass through the drop zone.

Though the drop zone avoided inhabited areas, it included regions where fisherman worked, and the flight path still flew over inhabited areas. The risk was extremely low, but it appears China also made no effort prior to launch to coordinate this situation with other governments, such as the Philippines. Its warning apparently arrived just before launch. Thus, there was risk that Filipino fisherman were in the drop zone at launch.

China to build giant ground-based optical telescope

China has announced its plan to build ground-based multi-segmented optical telescope, similar in design to the 10-meter Keck Telescope in Hawaii.

Peking University wants to build the largest optical telescope in Asia and close the gap in astronomy capabilities with the rest of the world.

The project aims to create an initial telescope with an aperture of 19.7 feet (6 meters) by 2024; the mirror will be expanded to 26.2 feet (8 m) by 2030. The project, which in English is called the Expanding Aperture Segmented Telescope (EAST), is being led by Peking University.

Like Keck, the primary mirror would be made of smaller segments, fitted together to create the larger mirror. While not as large as Keck, EAST would be among the largest in the world.

China’s Long March 3B rocket launches “experimental satellite”

China today successfully used its Long March 3B rocket to launch from an interior spaceport what its state-run press labeled an “experimental satellite.”

No word on where the rocket’s strap-on side boosters or first stage crashed within China.

The leaders in the 2022 launch race:

62 China
60 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 84 to 62 in the national rankings, but trails the entire world combined 94 to 84.

This launch cements for China the top spot in launches over SpaceX, since SpaceX only has one more launch planned in 2022, scheduled for just before midnight tonight.

China launches Earth observation satellite

China today successfully launched a classified Earth observation satellite using its Long March 4B rocket.

As the launch was from an interior spaceport, the rocket’s lower stages landed somewhere in the interior of China.

The leaders in the 2022 launch race:

61 China
59 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 83 to 61 in the national rankings, but trails the entire world combined 93 to 83.

At the moment, the only known remaining launches in 2022 are two SpaceX Falcon 9 launches. However, China routinely launches a lot in the November/December timeframe, so we should not be surprised if they complete one or two launches as well in the next few days.

  • Russian relations with Kazakhstan souring
  • Kazakhstan has “renounced concessions for Russian logistics companies that transport goods for import to Russia,” even as a Russian official threatened Kazakhstan with invasion. For the Russian space program these tensions could be disastrous, as the Baikonur spaceport in Kazakhstan is presently the only place it can launch humans.

 

China launches test satellite

The launch list changes immediately! China also completed a successful launched today, using its Long March 11 rocket to put an experimental satellite into orbit, designed to do “in-orbit verification of new space technologies.”

The rocket is solid-fueled, and designed to launch quickly as needed. No word on where its lower stages crashed inside China.

The updated leaders in the 2022 launch race:

The U.S. still leads China 81 to 60 in the national rankings, but trails the entire world combined 92 to 81.

China launches classified remote sensing satellite

Using its Long March 2D rocket, China last night successfully launched a classified remote sensing satellite into orbit.

The launch was from an interior spaceport. No word on where the first stage crash-landed.

The leaders in the 2022 launch race:

59 China
56 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 80 to 59 in the national rankings, but now trails the entire world combined 90 to 81.

Though SpaceX led China in successful launches for most of the year, China historically tends to do a lot of launches in the November-December time period. This is why it has surged ahead in the past month. SpaceX can still catch up, however, as it still has five launches planned for 2022. Either way, we will not know who comes out ahead until probably the end of the year.

That a private American company however has even a chance of beating out the entire world in annual launches is quite remarkable, whether or not SpaceX ends up ahead.
