China’s largest solid-fuel rocket motor
The China Academy of Launch Vehicle Technology (CALT) successfully conducted an ignition test of their largest solid-fuel rocket motor, expected to be used in future super heavy-lift launch vehicle Long March 9 (LM-9, Changzheng 9, CZ-9, 长征九号). The first three meters solid rocket engine was fired for 100 seconds, reaching a temperature of 3000 degrees Celsius, in Xi'an, Shaanxi province.
Who say CZ-9 rocket project has not approved yet? I can bet 2022-2025. China will send a man to moon. If better, China skipped moon and straight go for Mars and be the first country conducting manned mission to Mars.

Chinese scientists are researching a new type of aerospace vehicle that will take even those who have never had training to space in about 10 years' time at a much lower cost compared to the current price.

China Central Television (CCTV) reported Monday that scientists from China Aerospace Science and Technology Corporation have started work on a new vehicle integrating different kinds of engine technologies.

The vehicle will integrate air-breathing engines, such as turbine and ramjet engines, and rocket engine, which would allow it to operate as a normal plane in the atmosphere and as a rocket in space.

Researchers said the new vehicle will be reusable and take off and land at normal airports, without the need for special launch pads like the current rockets require, which will reduce cost substantially.

Zhang Yong, a scientist from the corporation, said they expect to master key technologies in about three to five years, and significantly improve the vehicle's capability during the application.

The vehicle is expected to be used for suborbital flight and orbital insertion by 2030, Zhang said. The expeditions will be between dozens to hundreds of kilometers from the earth.

Compared with the space shuttles and the partially recovered carrier rockets, the new vehicle integrating different engines has much more advantages in maintenance and application, CCTV reported.

In early July, China Academy of Launch Vehicle Technology, an institute of the corporation, said on its website that it was coordinating with other institutes to study the new vehicle.

Yang Yang, an engineer of the institute, said that common people will not need special training to travel to space on the vehicle.

He said the current rocket engine provides great propulsion during the start of flight, adding overload times of people's weights, which is unbearable for most people, but people would be able to endure the slow acceleration on the new vehicle.

Currently, people enjoy real space travels through two ways - the suborbital flight that allows people to enjoy couple of minutes of weightlessness but it costs more than $100,000 and the orbital flight that costs around $20 million.

Some private companies, especially in the US, can provide suborbital flights. But if people want an orbital flight, then they would have to go on a Russian space ship at present.

The US company SpaceX's carrier rocket with reusable parts has started cargo service to the International Space Station, but it is still unclear when it will be able to provide private space travel service and it might cost tens of millions, according to reports.
This is a great exciting news! Better than any reusable rockets. Can't wait for it.

Which they do. The S200 has a 3.2 m diameter and the P238 3.06 m. Slightly varied, perhaps, but certainly not to the extent that would invalidate any extrapolations that require the thrust-to-length ratio.
I suspect this guy is an Indy. Normal Chinese wont give a damn about an Indian rocket engine

Notice the subtle message he is repeating

You are trolling on racial issue?

汉Han is a Chinese character with many different meanings.

Dynasty, ethnic race, man of strong character, man, family names, name of rivers etc. .........

Earth science discussion latest sign of NASA-China ties

WASHINGTON — The head of NASA’s Earth science division, Michael Freilich, met with Chinese officials last month regarding potential coordination between the two countries on an upcoming Chinese mission, the agency said Aug. 4.

The meeting, first reported by the Hong Kong newspaper South China Morning Post but not initially confirmed by NASA, is the latest sign that the space agency is finding ways to work with China despite strict limitations placed by Congress on bilateral cooperation.

“As part of coordination discussions between NASA and the Chinese Academy of Sciences related to Earth science research, Dr. Freilich met with his counterparts at the Chinese Academy of Sciences on July 12, 2016, in Beijing,” NASA spokesman Steve Cole said Aug. 4.

The purpose of the meeting, Cole said, was “to discuss scientific data exchange and China’s plans for the launch of its new carbon monitoring mission, TanSat.” Cole did not disclose the outcome of the meeting, and said “no follow-up activities planned at this time.”

TanSat is a 500-kilogram satellite under development by the Chinese Academy of Sciences to measure carbon dioxide levels in the Earth’s atmosphere. The spacecraft is scheduled for launch late this year on a Long March 2D rocket.

The mission of TanSat is similar to NASA’s Orbiting Carbon Observatory 2 (OCO-2) spacecraft, launched in 2014. However, TanSat may be able to measure carbon dioxide levels with “unprecedented precision,” according to the South China Morning Post report.

China had previously expressed an interest in including TanSat in a constellation of Earth science satellites known as the Afternoon Constellation or A-Train, so named because the satellites pass over the Equator at 1:30 p.m. local time. The A-Train includes several satellites from the U.S., France and Japan that pass over the same region within minutes of each other, allowing for coordinated observations.

However, China opted to use a slightly different orbit “due to the complicated requirements and operational procedures for all participants in the A-Train,” according to a comment from a Chinese Academy of Sciences official provided to eoPortal, an Earth observation website run by the European Space Agency.

The discussions between NASA and the Chinese Academy of Sciences took place even though there are strict limitations on bilateral cooperation between NASA and Chinese entities. Language in appropriations bills in recent years largely restricts NASA and the White House Office of Science and Technology Policy from any cooperative efforts with Chinese organization.

The most recent language, included in the fiscal year 2016 omnibus spending bill passed in December 2015, prevents NASA and OSTP from spending funds “to develop, design, plan, promulgate, implement, or execute a bilateral policy, program, order, or contract of any kind to participate, collaborate, or coordinate bilaterally in any way with China or any Chinese-owned company.”

The bill, though, does allow such cooperation provided it does not involve the transfer of sensitive technology, or interactions with Chinese officials known to be involved in human rights violations, provided Congress certifies those plans at least 30 days in advance. Cole said that the July 12 meeting “was conducted in full accordance with all applicable U.S. laws.”

NASA is also cooperating with China in the area of aviation. In an Aug. 4 blog post on the NASA website, NASA Administrator Charles Bolden said that, after concluding ongoing meetings in Japan, he would visit China “to discuss areas of mutual interest in aviation research” with the Chinese Aeronautical Establishment (CAE).

“This will be part of ongoing conversations that began in November of 2014 and have continued through a NASA-CAE workshop in Beijing that was held in August 2015,” Bolden wrote.

Outside of NASA, where there are fewer restrictions on U.S.-China space cooperation, there have been meetings between the countries on both civil and military space issues. “Over the last year, we have made significant progress with China on space security and sustainability issues,” said Frank Rose, assistant secretary of state for arms control, verification and compliance, at a July 21 symposium on international cooperation in commercial space activities at the French Embassy here.

Those meetings included the first U.S.-China civil space dialogue, involving the U.S. State Department and the Chinese space agency, which took place in September 2015 in Beijing. A separate meeting between the two countries on space security issues took place in Washington in May.

Such meetings, he said, are evidence that the two countries can cooperate despite having differing views on space policy issues. “Despite the differences we have with Russia and China — and believe me, we have some serious differences with them on space security issues — there are also opportunities where we can find common ground,” he said.

We should have launch this years ago...shouldnt let those Westerners dominate this segment. I guess now we have the Chinese Iridium.

China prepares for new round of manned space missions

BEIJING, Aug. 6 (Xinhua) -- The rockets expected to carry China's second orbiting space lab Tiangong-2 and the Shenzhou-11 manned spacecraft into space have been delivered to Jiuquan Satellite Launch Center in northwest China.

A statement issued by the Manned Space Engineering Office on Saturday said that the center is where the assembly and tests of the rockets, which belong to the Long March-2F rocket series, will be carried out.

The rockets were sent from Beijing Wednesday by rail.

Compared with their predecessors, the two rockets feature technical improvements to improve their safety and reliability, according to China Academy of Launch Vehicle Technology.

Tiangong-2 is scheduled to launch in mid-September, and Shenzhou-11, which will carry two astronauts to dock with Tiangong-2, will be sent into space in mid-October.
