China just launch successful Tianzhou-1

complex coverage in Chinese
https://www.youtube.com/watch?v=mUvmH0u0M2k

This video show the Spacecraft testing and Launch complex in detail
but you have to skip the first 10 minutes for rocket fueling
https://www.youtube.com/watch?v=_MnOslJRYS4

I wonder wen first NASA or ESA official will ask: Why not use this one for ISS resupply also ?

Well ... if you're gonna steal, steal from the best.

*sigh*

Hey, Trump! How about protecting our intellectual property! Remember when Clinton sold guidance technology to the Red's? How come he's not picking up the soap bar in a prison shower? If I did that I would be the one backing out of the prison shower every night! (see: American submarine sailor who did time for a few photos taken in an old submarines engine-room).

I don't blame the Chinese -- they're taking the escalator, not the stairs. Smart. It's up to us to guard the gate. Our representatives are unwilling/incapable of doing so. Why is it so many representatives at the Federal level leave office as millionaires?

Sorry about the rant, but I see our government and treasure slipping away from us each day. Securing the vent.

Chinese space station: Beijing invites world to join its project as ISS support falters

IT’S testbed may have fallen to Earth earlier this year. But China says it has learnt enough to commit to building a massive new space station. And it’s invited the world to get aboard.

“CSS belongs not only to China, but also to the world,” UN ambassador Shi Zhongjun told the state-run Xinhua news agency. “All countries, regardless of their size and level of development, can participate in the co-operation on an equal footing.”

It’s an open hand of welcome that has been denied to China itself.

I wonder how long it will take China to build it own large space station, considering how long it took the west. And remember we had the Space Shuttle to help us carry the larger sections of the ISS.

It is going to be much smaller than ISS. They're planning for three segments. Figure that they could put two up in a year, a third the following year. It would be semi-operational when they launch the first module. So it's not going to take them long to get it up and working.

China follows a very careful, methodical pace with their human spaceflight program. There are no surprises with it, and it's very predictable.

I suppose that's the reason why so few Shenzhou flew since 2003. The Chinese knew that those flights have next to zero usefulness (bar propaganda) without a space station, so they flew an absolute minimum of them. The real question is whether there will ramping up the flight rate once they will get a space station running. On paper: from one shezhou every three year, to three Shenzhou a year (that was Soyuz classic flight rates in the days of Salyut and Mir and even ISS - 120 Soyuz in 40 years = three a year).

On paper: from one shezhou every three year, to three Shenzhou a year (that was Soyuz classic flight rates in the days of Salyut and Mir and even ISS - 120 Soyuz in 40 years = three a year).
I think there were several things behind that flight rate, but they can probably be best summarized into the following:

-engineering philosophy
-resources

The Chinese have demonstrated by now that their approach is to take fewer, bigger strides. They obviously have studied the American and Russian programs a lot, so they don't think that they need to do as many individual test flights.

It also appears that they don't have as much funding as the program managers would like. I think people in the West tend to look at a command-driven government like China and think that they simply make a decision and do it. But they have a lot of different levels in their government, and there have been indications that the people in the space program have wanted to do more, but the money has not come from the government to allow them to do all those things. So they've moved at a slower pace than many in the program would like.

But what I find so interesting (and indeed admirable) is that they seem to get as much out of each individual mission as possible to enable the next step. It looks like effective planning. Of course, that could also be because we're not seeing everything that is going on behind the scenes, including the false steps and mistakes.

China reveals details for super-heavy-lift Long March 9 and reusable Long March 8 rockets

A senior designer with the China Academy of Launch Vehicle Technology has presented updated details for an upcoming series of new rockets to expand China’s launch capabilities, including super-heavy-lift and reusable rockets.

Long Lehao, a chief designer with CALT, a major launch vehicle institute under the main contractor for China’s space activities, revealed the details in a lecture at Tsinghua University in Beijing on May 31.
The Long March 9 will be a Saturn 5-class super-heavy-lift rocket comparable in capacity to the Space Launch System currently being developed under NASA.

According to Long, the Long March 9 will be capable of lifting 140 metric tons to low Earth orbit, 50 tons to Earth-Moon transfer orbit, and 44 tons to Earth-Mars transfer orbit.

The 93-meter-high Long March 9 is expected to have a launch mass of over 4,000 metric tons, producing close to 6,000 tons of thrust.
The Long March 9 is slated to be ready for a test flight around 2030, with Long adding that progress on the project includes successful forging of 10-meter-diameter alloy rings and breakthroughs related to 500-ton-thrust kerosene-liquid oxygen and 220-ton-thrust hydrolox engines.
The first major mission of the Long March 9 is expected to be a single-launch Mars sample return mission, while the rocket is also being designed to facilitate lunar missions, including crewed landings.
Long explained in the lecture that the Long March 8 would be CALT’s first rocket to attempt first stage reusability, which will launch for the first time in 2021.

https://www.scmp.com/news/china/diplomacy-defence/article/2159891/string-chinese-satellites-keep-real-time-watch-south

China will next year start launching a series of satellites to track water conditions and traffic, and reinforce “national sovereignty” throughout the South China Sea, according to state media.

In all, six optical satellites, two hyperspectral satellites and two radar satellites will keep a real-time daily watch on the contested waters and monitor key areas several times a day as part of the Hainan satellite constellation system, China News Service reported on Monday.

Yang Tianliang, director of the academy’s Sanya Institute of Remote Sensing, said the network would enable authorities based in Hainan to speed up their response to emergencies, more effectively administer the South China Sea, and improve exploration and development of the resource-rich waters.

“Each reef and island as well as each vessel in the South China Sea will be under the watch of the ‘space eyes’,” Yang said. “The system will [reinforce] national sovereignty, protection of fisheries, and marine search and rescue.”

The programme is being carried out by the Chinese Academy of Sciences and is expected to be completed by 2021.

In the programme’s first phase, three of the optical satellites will be launched in the second half of next year. They will be equipped with optical remote sensors, a system to identify ships and cameras designed to monitor the ocean’s surface.

The network’s initial priority was to cover all of the South China, Sea so the cameras in the first three satellites will be strong enough only to focus on large and mid-sized vessels, the report said.

The two hyperspectral satellites to be launched in the second phase in 2020 will be able to assess water conditions, while the synthetic aperture radar satellites to be sent into orbit in the third phase will be able to provide all-weather, high-definition monitoring.

Yang said that when the network is completed, it will cover the entire area between the 30th north and south parallels, and could offer “seamless monitoring and receiving system” of tropical regions.

“This is will cover most of the Maritime Silk Road area,” he said when the programme was launched in December.

The oil and resource-rich waters of the South China Sea are claimed by China, the Philippines, Brunei, Vietnam, Malaysia and Taiwan.

Tensions have risen in the area with China’s construction of artificial islands equipped with military facilities, and the deployment of military vessels by other claimants and the United States.

China's Tiangong-2 to de-orbit after July 2019
BEIJING, Sept. 26 (Xinhua) -- China's Tiangong-2 space lab is functioning normally and will de-orbit safely after July 2019, according to a briefing on China's space projects Wednesday.
"Tiangong-2 is currently operating in a near-circular orbit with an average height of about 400 kilometers. The temperature and pressure of the experimental cabin all meet the working requirements," said Lin Xiqiang, deputy director of the China Manned Space Engineering Office, at the briefing.
"It will conduct compressor life tests and space science application tests in the future," Lin added.
Zhu Congpeng, chief designer of the space lab, said that Tiangong-2 was designed with several safety control modes to deal with emergencies and ensure it can safely leave orbit.
"We have also made more than 300 fault countermeasures to ensure its safe operation, " Zhu said.
Launched on Sept. 15, 2016, Tiangong-2 has been in orbit for more than two years.

China to conduct large-scale experiments in space station
BEIJING, Sept. 26 (Xinhua) -- China will carry out large-scale scientific experiments on space application projects after the completion of China's space station, according to a news briefing on China's space projects Wednesday.
China's manned space station is planned to be completed around 2022 and will be in orbit for more than 10 years.
"After the completion of the space station, space experiments and applications will become the main focus of the project," said Lin Xiqiang, deputy director of the China Manned Space Engineering Office, at the briefing.
Lyu Congmin, deputy chief designer of the space station's application system, said the space station will be a platform for more frontier space science experiments and applications.
"We have planned more than 13 laboratories and experimental platforms in the space station. A large optical telescope will be sent into the same orbit to fly with the station," Lyu said. "We will conduct more than 30 research projects in eight areas, including space astronomy, space life science and biotechnology, microgravity fundamental physics and space materials."
"The space station can support space applications in and out of the cabin, and the payload can be adjusted in orbit," said Lin. "I believe the large-scale experiments will bring more important achievements with international influence and application value."

https://www.scmp.com/news/china/science/article/2166413/will-chinas-new-laser-satellite-become-death-star-submarines

The title of the article is more than a bit over the top. :)

China is developing a satellite with a powerful laser for anti-submarine warfare that researchers hope will be able to pinpoint a target as far as 500 metres below the surface.

It is the latest addition to the country’s expanding deep-sea surveillance programme, and aside from targeting submarines – most operate at a depth of less than 500 metres – it could also be used to collect data on the world’s oceans.

Project Guanlan, meaning “watching the big waves”, was officially launched in May at the Pilot National Laboratory for Marine Science and Technology in Qingdao, Shandong. It aims to strengthen China’s surveillance activities in the world’s oceans, according to the laboratory’s website.

Scientists are working on the satellite’s design at the laboratory, but its key components are being developed by more than 20 research institutes and universities across the country.

Song Xiaoquan, a researcher involved in the project, said if the team can develop the satellite as planned, it will make the upper layer of the sea “more or less transparent”.

“It will change almost everything,” Song said.

A laser to reliably detect near-surface submerged vehicles is very challenging, one that can punch down 500m and come back with enough resolution to pinpoint a sub, from orbit, seems....ambitious. There's also the problem that it would have a very narrow FoV.

According some sources like NASASpaceFlight.com
In China work since 2013 China Academy of Space Technology (CAST ) on that Project.

That would explain why there is no more Shenzhou flight since 2016
China just switch to new Hardware

I wonder will this new Space craft be more NASA Orion or the PTK Federatsiya spacecraft or something completely new ?

Based on established chinese cultural and behavioral patters, I sincerely believe we can rule out "something completely new" with fairly high confidence...

The teaser image and previously published studies suggest they ripped off Dragon's basic shape this time.

Now here is the interest question What Company ?

This sound that SUPARCO made not a deal with the China National Space Administration (CNSA).
So made they a deal with new Private Companies that follow SpaceX success ?
