China launches another military satellite

The race between Russia, China, and SpaceX for the most launches in 2017 tightened today with another successful Chinese launch this morning of a classified military satellite using its Long March 2D rocket.

The race as of today:

27 United States
18 Russia
16 SpaceX
14 China

According to this article as well as SpacflightNow’s launch log), China, Russia, and SpaceX all have three more launches scheduled in 2017. If that is what happens, these standings will not change.

India and China to reduce launch costs

Capitalism in space: In response to the announcement by Chinese officials that they aim to reduce their launch costs in order to attract more commercial business, Indian officials announced that they plan to do the same in order to compete.

Interestingly, the reduced price that China revealed, $5,000 per kilogram, remains about twice that of SpaceX’s estimate per kilogram price for a launch using a reused first stage.

China successfully launches two satellites

China’s Long March 4C rocket successfully placed two satellites in orbit today, a weather satellite and a commercial data relay satellite.

This was China’s 11th launch in 2017, well below the 20 they achieved in 2016, the drop caused by two launch failures earlier this year that resulted in an almost four month pause in launches.

At present the race for the most launches in 2017 stands as follows:

17 Russia
16 SpaceX
11 China
10 Arianespace (Europe)
7 ULA
5 Japan
4 India
3 Orbital ATK

Overall, the United States leads with 26 launches, its most since 2000.

ESA to lead international effort to track falling Chinese space station

The European Space Agency has taken the lead position in an international effort to track China’s falling Tiangong-1 test space station module.

The goal of the effort is to improve the accuracy of predicting the fall of such objects. Tiangong-1, at 8.5 tons, is big enough for some pieces to survive re-entry and crash to the ground. Improving the predictions of where it will fall will reduce the chances of the debris causing harm.

I first read of this effort from this news story, which contained in its last sentence one piece of interesting news having nothing to do with Tiangong-1:

The next such launch [of a Chinese space station module] will be of the Tianhe core module around 2019 on a new Long March 5B rocket, the country’s largest and most powerful so far. [emphasis mine]

It appears China has quietly renamed its big Long March 5 rocket, adding a “B” to the name. This name change strongly indicates what I have suspected for months, that the July launch failure has required China to significantly redesign the rocket. Apparently, the poor performance of the rocket’s first stage engines was caused by fundamental design problems.

China says Long March 5 will resume launches in 2018

The new colonial movement: Though the details are vague, a Chinese official said earlier this week that they now expect to resume launches of their Long March 5 rocket in 2018.

The article says that the July launch failure of the second Long March 5 was due to “a manufacturing defect affecting one of two YF-77 engines powering the first stage. If officially confirmed, this would mean no major effects such as redesign are required, meaning a relatively swift return to flight.”

The long delay since July however suggests to me that the defect was more serious, and has either required that redesign or a complete recall of all YF-77 engines.

Chinese company gives live turtle a high altitude balloon flight

Capitalism in space: Chinese company has successful given a live turtle a high altitude balloon flight as prep for future tourism flights.

The news article is somewhat humorous in claiming the following:

Shenzhen-based Kuang-Chi Group said it blasted the yellow-headed turtle, nicknamed “Little Cloud”, to an altitude of 21,000 metres inside a helium-filled craft. The launch took place from western China’s Xinjiang region at about 4am on Wednesday morning.

The craft landed safely at about 8.28am the same day, and the turtle was said to have survived the trip.

The company said it was the first time a live animal had been safely taken into near space, and that the trip paved the way for it to sell commercial flights to humans by 2018 or 2019. [emphasis mine]

The company’s claim, highlighted above, is so incredibly not true it raises questions about their whole story. Humans have been taken by balloon to these elevations several times. This might be a poor translation, but then it indicates some incompetence by the reporter.

Either way, this company is aiming for the high altitude tourism market that World View in Tucson had initially been focusing on, but now seems to have abandoned.

Posted as we slog our way through Phoenix traffic.

Cause of Long March 5 July failure is in “first-stage propulsion”

In an interview earlier this week a Chinese official revealed that the problem during the July Long March 5 launch was related to an issue with “first-stage propulsion.”

The official only added that the investigation is “on-going” and that they intend to fix the problem because the Long March 5 is needed for China’s human and deep space programs.

The vagueness here suggests to me the possibility of some very fundamental problems that might be requiring a major redesign. That is a pure guess, however, and should not be taken very seriously.

China’s first test space station, Tiangong-1, is out-of-control

The orbit of China’s first test space station, Tiangong-1, is quickly decaying and the station is shut down with no way to bring it down in a controlled manner.

The Chinese space station is accelerating its fall towards us and will reach the ground in the coming months, Harvard astrophysicist Jonathan McDowell told the Guardian. It is decaying quickly and he expects “expect it will come down a few months from now – late 2017 or early 2018”, he told the paper.

The Tiangong 1 station was launched in 2011 as one of the great hopes of the Chinese ambitions in space, and as part of a plan to show itself off as a global superpower. The country’s space agency referred to the station as the “Heavenly Palace” and conducted a range of missions, some of which included astronauts.

But last year scientists at Chinese’s CNSA space agency said that they had lost control of the lab, and that it would now be heading towards Earth. That put an end to months of speculation, as experts watching the path of the station suggested that it had been behaving strangely.

As with many other similar objects coming down from orbit, the odds of any pieces hitting anyone is quite small. Still, China is a signatory to the Outer Space Treaty, and that makes them liable for any damage done by their spacecraft when they return to Earth.
