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

Quote
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.

Quote
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.

Quote
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.

Quote
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.

Quote
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.

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."

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.

Unpossible.  I was told SSBNs would be impossible to detect for the foreseeable future.  ;)
"DARPA Hard"  It ain't what it use to be.

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 ?
I love Strange Technology

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.
