China completes first launch of 2019, followed by SpaceX

9:24 am

The new colonial movement: China yesterday successfully completed the first launch of 2019, sending a military communications satellite into orbit with its Long March 3B rocket.

It is my impression, from various sources, that China might not launch quite as many rockets in 2019 as it did in 2018. Like SpaceX in the past two years, it was clearing out a backlog of launches caused by the failed launch of their biggest rocket, Long March 5, in 2017.

Still, I expect an active year from China. It is going to be very interesting to watch the 2019 launch race unfold. SpaceX for example has just successfully launched ten Iridium satellites into orbit, the first launch from Vandenberg this year, successfully landing the first stage on a barge.

Right now the U.S. and China are tied in the 2019 launch race, 1-1.

Want to see a panorama of Chang’e-4 landing site? You can!

8:36 am

If you want a really good look at the Chang’e-4 landing site on the far side of the Moon — with Yutu-2 about thirty feet away — photographer Andrew Bodrov has produced a spectacular 360 degree panorama from images sent down by the lander.

This panorama reveals two things. First, the lander landed close to two small craters, which it thankfully missed. Second, there are some hills in the distance which I suspect are central peaks of Von Kármán crater. They are probably beyond Yutu-2’s range, but would make a worthwhile exploratory target.

Meanwhile, the rover and lander have come back to life after a brief hibernation to protect them from the heat of the lunar mid-day.

Finally, China has released a video showing Chang’e-4’s descent and landing, which I have embedded below the fold. In it, you can see the spacecraft computer maneuver to land between those two craters shown in the panorama.

Chinese rocket company tests vertical landing

9:04 am

The new colonial movement: A Chinese rocket company has conducted its first vertical flight and landing tests of a prototype rocket.

Linkspace…has tested a tech demonstrator reusable rocket similar in utility to the Grasshopper rocket SpaceX used in its development of the Falcon 9 launch vehicle. The RLV-T5 technology demonstrator, also known as ‘NewLine Baby’, for vertical takeoff, vertical landing (VTVL) is designed to verify key technologies including variable thrust, multiple engine restarts and roll control with its flight and recovery tests, according to the press release (in Chinese).

The latest footage, released on Sunday, shows a tethered test which followed three months of preparations. The demonstrator is 8.1 metres high with a mass of 1.5 tonnes and uses five variable thrust engines. Linkspace now describes itself as the world’s third-largest recyclable rocket development team, after SpaceX and Blue Origin.

The article also describes an engine test by a different Chinese company. Both are being touted as part of China’s new private space effort, but I find myself somewhat skeptical. China might have given these companies some independent leeway, but in the end nothing they do is unsupervised by the Chinese government.

Regardless, they are making technical progress. It appears that Linkspace is aiming for a suborbital test flight later this year.

Using LRO to find Chang’e-4

8:49 am

LRO image of Chang'e-4 landing area

The Lunar Reconnaissance Orbiter (LRO) science team has released a high resolution image from 2010 pinpointing the area on the floor of Von Kármán crater where Chang’e-4 landed. On the right is a reduced and partly annotated version.

They have not actually found the lander/rover, since this image was taken long ago before Chang’e-4 arrived. However, this image, combined with the Chang’e-4 landing approach image, tells us where the lander approximately landed. It also pinpoints where to look for it when LRO is next able to image this region, around the end of January.

By then, Yutu-2 will hopefully have traveled some distance from Chang’e-4, and LRO will be able to spot both on the surface.

Yutu-2 has rolled out and has begun roving

8:29 am

The new colonial movement: China’s second lunar rover, Yutu-2, has rolled off of the Chang’e-4 lander and begun its roving.

Yutu will rove within Von Kármán craterand analyse the variations of composition of the lunar surface the Visible and Near-Infrared Imaging Spectrometer (VNIS), while also returning unprecedented images with a panchromatic camera.

The rover’s two offer science payloads, the Lunar Penetrating Radar (LPR) and Advanced Small Analyser for Neutrals (ASAN), the latter developed by the Swedish Institute of Space Physics in Kiruna, will provide insight into the lunar subsurface to a potential depths of hundreds of metres and the space environment and interactions with the surface respectively.

Chang’e-4 successfully lands on far side of Moon

10:24 pm

The new colonial movement: China’s Chang’e-4 lander/rover has successfully landed on far side of Moon.

Early reports of a successful landing sparked confusion after state-run media China Daily and CGTN deleted tweets celebrating the mission. China Daily’s tweet said: ‘“China’s Chang’e 4 landed on the moon’s far side, inaugurating a new chapter in mankind’s lunar exploration history.”

Official confirmation of the landing came two hours later via state broadcaster CCTV, which said the lunar explorer had touched down at 10.26am (2.26am GMT). The Communist party-owned Global Times also said the probe had “successfully made the first-ever soft landing” on the far side of the moon.

No reason has been given for the deletion of the tweets, though I suspect they did so because they were simply premature.

Update: More information here, including images.

The 2018 global launch race plus predictions for 2019

11:45 am

In 2018 the global launch industry turned a significant corner. While there have been strong signs in 2016 and 2017 that we were about to see the arrival of a boom, it was not until this past year that we finally saw the beginnings of this boom.

Below is my updated launch graph showing what was accomplished in 2018. To put what was done in context, the graph shows all launches by every nation and private company for each year beginning in 1980, with 1968 added to provide a sense of what the launch industry was like during the height of the Cold War space race.

Before reading further, however, it is worthwhile to review what I wrote in my 2017 launch industry assessment, written in January 2018. My assessment then, as well as my predictions, provide some worthwhile context for understanding what actually happened this past year.

Engineers adjust Chang’e-4’s orbit

7:39 am

The new colonial movement: Engineers have adjusted Chang’e-4’s lunar orbit in preparation for landing.on the Moon’s far side.

The probe has entered an elliptical lunar orbit, with the perilune at about 15 km and the apolune at about 100 km, at 8:55 a.m. Beijing Time, said CNSA.

Since the Chang’e-4 entered the lunar orbit on Dec. 12, the ground control center in Beijing has trimmed the probe’s orbit twice and tested the communication link between the probe and the relay satellite Queqiao, or Magpie Bridge, which is operating in the halo orbit around the second Lagrangian (L2) point of the earth-moon system.

The space engineers also checked the imaging instruments and ranging detectors on the probe to prepare for the landing.

They need to time the landing so that it comes down in the Moon’s early morning. This will not only provide better visuals, with shadows to see surface details, but more importantly will give them 14 Earth days before sunset to get settled on the surface and initiate rover operations.

China launches first of planned 320 communications satellite constellation

8:38 am

The new colonial movement: China today used its Long March 2D rocket to launch the first satellite in a proposed 320 satellite constellation designed to provide worldwide phone service.

The Hongyan constellation is composed of more than 320 satellites, along with data processing centers, and will be built in three stages. The orbital group will consist of 54 main satellites, accompanied by another 270 smaller satellites for coordination of the system.

Six or nine satellites will be launched before the end of 2020 for network testing. The 54 larger first phase satellites will be placed in orbit by the year 2023 and the 270 smaller satellites will be placed into orbits to supplement the main satellites.

Once completed, the satellite communication network will take the place of the ground-based network and allow a mobile phones to be connected everywhere on the planet, either in a remote desert or at sea, according to CASC. The project has drawn an investment of about 20 billion yuan (about 2.9 billion U.S. dollars) for its first phase, making it the largest investment for a single commercial aerospace program in China.

This constellation is essentially in direct competition with Iridium.

This is likely China’s last launch for 2018. It is also likely to be the last launch this year, since the ULA launch that had been planned for December 30 has now been pushed back a week. The leaders in the launch race:

38 China
21 SpaceX
15 Russia
11 Europe (Arianespace)
8 ULA

In the national rankings, China tops the U.S. 38 to 34. It also came only two launches short of meeting its ambitious goal of 40 launches in 2018, an achievement that pretty much doubled its previous launch record.

I am preparing my annual launch report. Stay tuned.

China launches first prototype of new low-cost communications constellation

7:57 am

The new colonial movement China today launched the first prototype Hongyun communications satellite.

Developed by the China Aerospace Science and Industry Corporation (CASIC), this is the fist satellite of a vast space-based communications network capable of covering every corner on the Earth, including the Arctic and Antarctica. The satellite mission is to verify low-orbit broadband communication technologies to be used on the Hongyun satellite constellation.

Announced by CASIC in September 2016, the Hongyun project has the goal of building a space-based communications network of 156 communications satellites into low Earth orbit, at an altitude of 160 to 2,000 km. Each satellite of the network will be able to transmit 500 megabytes of data per second. It will become operational in 2022.

These satellites, aimed at lowering cost, appear to be in direct competition with many of the new smallsat constellations being developed in the west by SpaceX, OneWeb, and others.

The leaders in the 2018 launch race:

36 China
20 SpaceX
14 Russia
11 Europe (Arianespace)
8 ULA

China has widened its lead over the U.S. in the national rankings, 36 to 33, and has likely now clinched that lead for the year. Stay tuned for my annual full report on the state of the launch industry in 2018.

A detailed look at Chang’e-4

9:58 am

Link here. Lots of nice information, including the fact that Chang’e-3 seems to still be functioning in a limited manner, and that Chang’e-4 is depending not on solar panels but a radioactive thermal electric system, similar I think to the RPGs that NASA uses on its deep space missions. (I am uncertain however about this, based on looking at the video at the link, which seems to show solar panels on Chang’e-4. They could be instead panels to protect the spacecraft from the sun’s heat.)

They enter lunar orbit on December 12, and will likely land in the first week of January.

China launches lunar rover/lander Chang’e-4; Saudi satellites

12:09 pm

Using its Long March 3B rocket, China on December 7 successfully launched its Chang’e-4 rover/lander, aimed at being the first probe to land on the Moon’s far side.

It will take the probe five days to reach the Moon and land.

The same day China also launched two Earth observation satellites for Saudi Arabia, using its Long March 2D rocket.

The leaders in the 2018 launch standings:

35 China
20 SpaceX
13 Russia
10 Europe (Arianespace)

China has widened its lead over the U.S. 35 to 32 in the national rankings. China also looks like it is going to come close to meeting its prediction of 40 launches for 2018.

Electric cars routinely transmit info to Chinese government

9:44 am

The Big Green government: Manufacturers of electric cars design the cars so that they routinely transmit information about the car’s status and position to the Chinese government.

More than 200 manufacturers, including Tesla, Volkswagen, BMW, Daimler, Ford, General Motors, Nissan, Mitsubishi and U.S.-listed electric vehicle start-up NIO, transmit position information and dozens of other data points to government-backed [Chinese] monitoring centers, The Associated Press has found. Generally, it happens without car owners’ knowledge.

The automakers say they are merely complying with local laws, which apply only to alternative energy vehicles. Chinese officials say the data is used for analytics to improve public safety, facilitate industrial development and infrastructure planning, and to prevent fraud in subsidy programs.

Outside of China the information is also gathered, but by private companies. Car owners can opt out, but that seems to me to be the unethical way to arrange this. Owners should instead be asked if they want to opt in.

In fact, the gathering of this data, privately or by governments, without the permission of the car owner, is entirely unethical and immoral. That these companies and their managers see nothing wrong with this is another illustration of the abandonment of morality in modern culture. It is also another reason why I want my hi-tech equipment to be as dumb as possible. Above all, I do not want it linked electronically beyond itself.

China successfully completes another launch

9:19 am

China successfully launched five satellites yesterday using its Long March 2D rocket.

The main payload is apparently a military surveillance satellite.

The leaders in the 2018 launch race:

33 China
18 SpaceX
11 Russia
8 ULA
8 Europe (Arianespace)

China has widened its lead on the U.S. to 33 to 31. There have also been 93 successful launches this year, which ties 2014 for the most in the 21st century. My count of the number of future launches so far announced suggests that there will be about 110 launches total in 2018, the highest number since 1990, the year before the fall of the Soviet Union.

China launches two GPS-type satellites

9:25 am

China yesterday used its Long March 3B rocket to successfully launch two more GPS-type satellites for its planned Beidou constellation of 35 satellites.

They have launched about half the constellation this year, and plan to complete it next year.

The leaders in the 2018 launch race:

32 China
18 SpaceX
11 Russia
8 ULA
8 Europe (Arianespace)

China has widened its lead over the U.S. to 32 to 30 in the national rankings. China also seems on schedule to meet or at least come very close to its predicted 40 launches this year, a number that doubles its previous high.

China still struggling to find scientists to run FAST radio telescope

8:32 am

China is still finding it difficult to hire the scientists necessary to run its FAST radio telescope, the largest single dish radio telescope in the world.

And why is that?

For job candidates, the major stumbling blocks often are financial incentives and research independence, researchers told the South China Morning Post. The telescope’s remote location also may give candidates pause.

George Smoot, a Hong Kong University of Science and Technology professor who won the Nobel Prize in physics in 2006, said candidates interested in working in a more developed setting might think twice about spending a lot of time in an area known for its traditional rural villages.

“Another issue is how much the Chinese Academy of Sciences will influence and direct activities there,” Smoot said. “It is an issue to people unless they have some straight link.” [emphasis mine]

It must always be remembered that nothing in China is done without the government’s approval. For western astronomers, used to having a great deal of independence, this fact makes working there somewhat unappealing.

China tests its own grasshopper

10:02 am

China has completed its first vertical rocket landing test, using a prototype small scale first stage very similar to SpaceX’s Grasshopper test rocket.

If I was cynical, I’d say that this isn’t just similar, it is a direct steal from Grasshopper. But then, that is generally how the Chinese have come up with their new technology, not by creating it themselves, but by stealing ideas from others and then upgrading them.

Either way, this test shows that China is devoting serious energy to making its first stages reusable.

Pakistan enlists China to launch its 1st astronaut by 2022

8:54 am

The new colonial movement: Pakistan has begun negotiations with China to launch its first astronaut by 2022.

Plans are afoot to send Pakistan’s first astronaut to space with China’s help in 2022, the country’s Information Minister Fawad Chaudhry announced on Thursday, saying the proposal got a nod from the federal Cabinet at a meeting chaired by Prime Minister Imran Khan ahead of his maiden visit to China next week.

An agreement between Pakistan Space and Upper Atmosphere Research Commission (SUPARCO) and a Chinese company has already been signed for the ambitious mission, Lahore-based The News daily cited Chaudhry as telling a press conference after Thursday’s Cabinet meeting. There’s no official confirmation of the project from Chinese officials yet.

Last December, Pakistan’s Air Chief Marshal Sohail Aman had also said that Islamabad will collaborate with China to send astronauts to space, Karachi-based ARY News reported.

There is zero doubt that Pakistan’s leaders started these talks after learning of India’s plans to launch its own manned mission in 2022. Unlike India, a religiously tolerant capitalist democracy, Pakistan (an Islamic dictatorship) does not have its own space capabilities. To compete with India it will need to hire someone else to provide the rocket and manned spacecraft.

China has said it wants to fly international visitors to its space station, expected to be in operation in 2022. This deal fits the needs of both nations, perfectly.

Chinese smallsat rocket fails to make orbit

8:16 am

One of the handful of so-called private companies being used by China’s military to develop smallsat solid-fueled rockets, LandSpace, today tried to put its first satellite into orbit, and failed.

The satellite was for Chinese television, but I find the links to China’s military for this rocket too many to dismiss. I initially saw them as direct competition with the new smallsat rocket companies developing in the west, but I got suspicious when I found they all had remarkably similar names (LandSpace, OneSpace, Exspace, ISpace) and that all seemed to be using solid-fueled rockets, most of which were being launched from mobile launchers. Such rockets are almost always developed for military purposes.

These companies might be providing China some commercial services, but they are probably also aimed at giving its military a mobile orbital rocket that can do other things as well.

China launches two GPS-style satellites

8:43 am

In launching two more GPS-style satellites with its Long March 3B rocket, China today also did their first test of equipment to be used in a parachute system designed to recover the rocket’s first stage.

The China Aerospace Science and Technology Corporation (CASC) confirmed the mission to be a success four hours later, following direct insertion of the Beidou-3 satellites into their intended medium Earth orbits (MEO).

The China Academy of Launch Vehicle Technology (CALT) which developed the Long March 3B rocket reported that data logging and active tracking equipment was placed aboard for tests to determine to altitude and timing for future parachute landings for boosters.

The trial phase of parachute booster landings is expected in 2019. Expended rocket boosters frequently land in or near populated areas downrange of Xichang.

It is about time. The article also included a short video showing the booster wreakage that landed near a town during a previous launch. For any nation to allow rocket stages crashing near habitable areas speaks poorly of that nation.

The leaders in the 2018 launch race:

28 China
17 SpaceX
8 Russia
7 ULA
6 Europe (Arianespace)

In the national rankings China leads the U.S. now 28 to 25. I must add that with every launch China is setting a new record for itself in its annual totals. Previously its highest total of launches in a year had been 20.

China plans next Long March 5 launch for January 2019

9:19 am

The new colonial movement: China has begun the assembly of the third Long March 5 rocket for its next launch, now set for January 2019.

The article provides the most detailed information yet released about the failure during the rocket’s second launch:

The cause was determined to be damage to the turbopump on one of the two cryogenic YF-77 first stage engines, prompting a redesign of the structure and test-firing in Xi’an.

This is still somewhat vague, though it does confirm that the rocket engine needed a redesign.

Should this January 2019 launch go well, it will allow China to move forward on all of its ambitious space exploration plans, including the building of its own space station, numerous robotic missions to the Moon and Mars, followed eventually with manned missions to the Moon.

Link here. Chang’e-4 is set to land on the far side of the Moon, sometime in December. The article provides some additional details, including information about the likely landing site in Von Kármán crater. It also notes that there are three launches planned at the spaceport prior to the December launch, and that any issue on any of those launches could delay Chang’e-4’s lift-off. .
