The new colonial movement: To celebrate the completion of a year on the lunar surface, China has released the bulk of the data and images produced by the lander Chang’e-3 and the rover Yutu-2.

The link includes a nice gallery of images. I especially like the image to the right, cropped to post here. It shows Yutu-2 moving away from Chang’e-3 early in the mission. It also shows how truly colorless the Moon is. The rover proves this is a color image, but if it wasn’t in the shot you’d have no way of knowing.

And then there is that pitch black sky. I wonder what’s behind it.

China completes first launch of 2020

The race is on! China today successfully launched a military satellite using its Long March 3B rocket, China’s second most powerful rocket behind the Long March 5.

Right now SpaceX and China are tied with one launch in the 2020 launch race. Based on the 2020 launch estimates from both, I expect that we will see a neck-and-neck race for the most launches from each for the rest of the year.

China now predicts more than 40 launches in 2020

The new colonial movement: China has increased its launch prediction for 2020 from 30 to more than 40 launches.

The key planned achievements:

The highlights of the space activities include the launch of China’s first Mars probe, the Chang’e-5 lunar probe, which is expected to bring moon samples back to Earth, the final step of China’s current lunar exploration program, as well as the completion of the BeiDou Navigation Satellite System constellation.

Three new types of carrier rockets including the Long March-5B, Long March-7A and Long March-8 will make their maiden flights in 2020.

It sure looks like 2020 is shaping up to possibly be the most spectacular year for space since Sputnik.

Yutu-2 completes 13th lunar day

China’s Yutu-2 lunar rover and its lander Chang’e-4 have completed their thirteenth lunar day on the far side of the Moon and have been placed in sleep mode.

During the twelve lunar day the rover traveled about 12 meters, or about 40 feet.

The rover has found materials from deep inside the moon that could help unravel the mystery of the lunar mantle’s composition and the formation and evolution of the moon and the earth. Using data obtained by the visible and near-infrared spectrometer installed on Yutu-2, Chinese scientists found that the lunar soil in the landing area of the Chang’e-4 probe contains olivine and pyroxene which came from the lunar mantle deep inside the moon.

Due to the complicated geological environment and the rugged and heavily cratered terrain on the far side of the moon, the rover drives slowly but steadily and is expected to continue traveling on the moon and make more scientific discoveries.

The state of the global rocket industry in 2019

With 2019 ending, it is time once again (as I did for 2016, 2017, and 2018) to review the trends in the global launch industry for the past year.

Below is my updated graph, showing the launch numbers for 2019 as well as for every year going back to 1990, just before the fall of the Soviet Union. That range I think covers all recent trends, while also giving some perspective on what happened in 2019.

The graph is worth reviewing at length, as it not only gives a sense of recent trends, it also summarizes well the history of the entire global space industry during the past thirty years. For example, it shows the transition in the U.S. in the past two decades from government-owned launchers to private rockets, a change that has revitalized the American space industry in more ways than can be counted.

China has a shortfall of jet engines

Apropos of the engine problems on the Long March 5, it is reported today that China has a serious manufacturing shortage of the jet engines it needs for its new stealth fighters and bombers.

Aviation website Alert 5 spotted a stock-exchange filing by the Hebei subsidiary of Chinaโ€™s Central Iron & Steel Research Institute. The filing including production projections for military engines for the next decade, and reveals some startling shortfalls. Production and development gaps could result in the latest Chinese warplanes flying with older engine models, including imported Russian motors that might be underpowered and unreliable. The mismatch between airframes and engines could be a drag on the overall performance of Chinese military aircraft.

Perhaps the biggest shortfall is in the production of WS-15s and WS-19s, the custom motors respectively for J-20 stealth fighters and FC-31 export stealth fighters. โ€œData provided by Hebei Cisri Dekai Technology Co. Ltd. shows a maximum of only five WS-15 and WS-19 engines each year from 2020 โ€˜til 2026,โ€ Alert 5 reported.

Apparently China will be flying these jets and bombers using inadequate Russian engines for the next five to eight years, as the country’s own industry seems unable to make them.

Yutu-2 sets new longevity record for lunar rover

China’s Yutu-2 lunar rover has now set a new longevity record for any rover on the Moon, beating the 10.5 month record set by the Soviet Union’s Lunokhod 1 rover in 1970-1971.

Lunokhod 1 traveled about 6.5 miles, or about 34,000 feet, during its operation. Chinese engineers have been more cautious, moving Yutu-2 only about 1,132 feet in the same time period.

The Chinese rover is still operating, though relatively little data has been released from it. At the moment it has been placed in its hibernation mode as it makes it through its twelfth lunar night.

China launches two more Beidou GPS-type satellites

The new colonial movement: China today used its Long March 3B rocket to launch two more Beidou GPS-type satellites.

With this launch China has successfully matched its predicted number of launches for 2019, a number that it should exceed with several more launches scheduled before the end of the year.

The leaders in the 2019 launch race:

30 China
20 Russia
12 SpaceX
7 Europe (Arianespace)

China now leads the U.S. in the national rankings 30 to 25. These numbers should change later today, as SpaceX has a commercial launch scheduled.

New info on Long March 5 launch failures

An article in the English Chinese press today about the upcoming third launch of China’s Long March 5 rocket revealed some new information about the failures of that rocket during its first two test flights.

On its maiden mission in November 2016, the rocket failed to reach the speed required for the early phase of the flight; still, extra booster fuel burned in the final stage lifted its satellite cargo into orbit and allowed China to declare the trip a success.

In the second flight a few months later, though, the main engine died minutes after take-off, and the rocket plunged into the sea.

I have tried to read every iota of information released about the first two launches of the Long March 5 in order to figure out what went wrong during its second launch. At no time however had I ever come across any report that described any launch problems during its first flight. The Chinese always touted that first flight as a complete success, with no problems.

We now learn that the first stage during that first launch was under-powered, a problem that was not dealt with before the second launch, resulting in the complete failure of that second launch.

This is the typical behavior one sees in a government-run top-down program. Rather than bluntly address problems to fix them, even if it means someone will be embarrassed, management acts to protect itself, hiding problems so as to avoid blame. The result is always more failures.

As long as China’s economy is booming and providing its government with lots of cash for its space program, such problems can be papered over and even overcome. The second however that economy begins to falter, the program will stumble, the hidden problems acting like an avalanche to overwhelm everything.

Scientists reject discovery of biggest known black hole

The uncertainty of science: In three new papers published this week astronomers have found that the announced discovery in early December of the biggest super-massive black hole ever found, 70 times the mass of the Sun, does not hold up.

In a recent study (a peer-reviewed study published Nov. 27), a team of scientists reported the discovery of the binary system LB-1, which contains a star and, according to the findings, a black hole companion 70 times the mass of our sun. This was major news, a stellar-mass black holes (black holes formed by the gravitational collapse of a star) are typically less than half that massive. But while the study, led by Jifeng Liu, of the National Astronomical Observatory of China (NAOC) of the Chinese Academy of Sciences, was exciting, it was also wrong.

Three new papers came out this week that reexamined the findings from Liu’s study, and these studies say that LB-1’s black hole isn’t actually all that massive.

The new papers find that a closer look at the data finds that it wasn’t doing what the initial researchers thought.

Two Chinese Kuaizhou-1A launches within six hours

The new colonial movement: China today successfully completed two separate Kuaizhou-1A launches, placing in orbit seven total smallsats and doing it within a space of only six hours.

China launched two orbital missions from the Taiyuan Satellite Launch Center within six hours of each other, orbiting a total of seven satellites. The launches, using mobile pads, saw two Kuaizhou-1A rockets heading into space on Saturday at 2:55 UTC and 8:52 UTC.

The first Kuaizhou-1A rocket, serial number Y2, orbited the Jilin-1 Gaofen-2B remote sensing satellite for the Jilin-1 constellation.

…Six hours after the first launch, and as was expected by the navigational warnings previously published, a second Kuaizhou-1A launch vehicle, serial number Y12, had already been displaced to the launch site, but from a different pad. Analysis of the images available from the second launch seems to indicate that launch took place from a location within the Launch Complex 16 usually used for the Long March-6 launches. Ignition came at 8:52UTC.

The three-stage launch vehicle orbited six satellites.

This achievement is a very big deal. China has demonstrated the ability to launch and then launch again quickly with this military-based mobile launch system. This not only enhances their commercial value, it tells us they have developed a military capability able to put payloads into orbit at almost a moment’s notice.

The leaders in the 2019 launch race:

29 China
19 Russia
12 SpaceX
7 Europe (Arianespace)
6 Rocket Lab

China now leads the U.S. 29 to 25 in the national rankings.
