China's new rockets (Long March 5 to Long March 9) are too big to be taken by train to the existing space centers - the train tunnels are too narrow. To over come this, the Chinese government set about building a new space center on the Island of Hainan in south China. It was to have been completed last month but no news yet that it has happened. Some info on the center from spacecalendar.com issue June 2-8, 2014.


Construction at the Wenchang Satellite Launch Center (WSLC) on the island of Hainan in southeast China is set for completion this month. The 20-square kilometer ~US$330-million project includes two main launch complexes LC101 and LC102, a rocket assembly plant, a command center, two tracking stations and various offices. With relatively clear flight paths over water East toward GTO, South toward SSO and Southeast toward LEO, Hainan offers safe operational conditions close to population centers and thus provides major opportunities for community engagement. Chengmin Pei, Party chief of Wenchang, expects the launch center to boost tourism to this already well established destination, the self-styled “Hawaii” of China. There are plans for a grand space theme park and space research center. Pei estimates that the first launch could draw 300,000 visitors to the city. In addition to low-latitude (19°N) and therefore highly efficient launch profiles, the site offers more geographical advantages. Every other China launch facility is constrained by railroad transportation infrastructure to an overall rocket width of 3.35 meters, whereas coastal Wenchang allows much larger boosters, specifically the Long March 5 & 7 currently in development, to arrive by sea from manufacturing sites in Tianjin. WSLC will enable ambitious future Moon missions and large scale Space Station development.

To start this thread I have included a short article on the proposed new rockets. We will get more information in the next year when Long March 5 and possible Long March 7 will be launched.

It has seemed like that for well over a year (http://aviationweek.com/awin/long-march-5-rocket-delayed-2015).
They were both originally to have their maiden flights in 2013.



I'm still trying to sort out the difference between the 5 and 7. The more I look, the more it doesn't seem like the numbering doesn't align with payload capacities. It seems more like they are completely different target missions. Probably just the ratio of first and second stage capabilities.

My personal opinion is the space port has been completed. They are now waiting for the availability of the right VIPs to do the opening ceremony.

The Long March 7 is the ferry for their astronauts.

Tentatively. What gets me is that LM5 capability is quoted in LEO and GTO while LM7 is quoted in SSO. So; it's hard to tell what the capabilities are in an apples to apples way.

Bad news. The space centre took a direct hit from a super typhoon over the weekend. Damage still being assessed.
This will impact the time line to test the new rockets. Which will have a knock on affect on the space station construction and the planned moon probes.
See image of the typhoon over the island in "China Space " on Facebook.

Some information on the typhoon

" Rammasun, known locally as “Glenda,” was the strongest typhoon to hit China’s south in four decades, resulting in 608,000 being evacuated, reports Xinhua News Agency.
In China, the island province of Hainan suffered the most destruction with 51,000 houses and 100,000 acres of crops wiped out. It also caused £1billion worth of damage in that region alone."

On August 29, the propulsion system of CZ-7 rocket Core Stage 2 completed the hot-fire test successfully.

http://en.cmse.gov.cn/show.php?contentid=1400


CZ-7 rocket is China’s new-generation medium-lift launch vehicle with a near-earth orbit capacity of about 13 tons. It is designed to launch cargo vehicles in the construction of the future space station. The propulsion system hot-fire test of CZ-7 rocket Core Stage 2, an essential large-scale ground test, is the last hot-fire test of the propulsion module following booster and core stage tests. The test is aimed at demonstrating the validity of the design of the propulsion system of Core Stage 2, checking the compatibility of the rocket with the ground system and obtaining relevant test data. It will pave the way for the following development work.

CZ-7 rocket Core Stage 2 is powered by four LOX/kerosene engines. During the test, the engines were fired normally and shut down at scheduled time. During the firing, each system functioned in good order. Judging from the test data, the test achieved huge success with all the parameters meeting the demands of the design.

The article is supposed to be about "SpaceX Proves Challenging To China's Long March Launcher" but it gives more information on the Long March 7 than I have read else where.

http://aviationweek.com/space/spacex-proves-challenging-chinas-long-march-launcher


Until last year, the Long March 7 was scheduled to fly in 2013. The first launch was then pushed to 2014. The year is not over yet, but there has been little activity to suggest that a first flight is imminent. Indeed, CASC has still been involved with major development aspects in recent months. That work may give a clue to difficulties that have been encountered.

In particular, CASC said in July that the propulsion system of the Long March 7 had passed a second test that had mainly validated what it called the system for high-pressure supply (of propellant, presumably) and the “compatibility with the engine, control system, measurement system and launch ground support system.” Developers implemented more than 10 changes to address weak links revealed in a first test, CASC says. “The whole test program is normal,” it adds. “All test data is matching predictions. The changes have been effective.” This was also the last test for the first stage, indicating that its development is complete, the manufacturer says. Last year a senior CALT official said the engines for the new family were ready and were not the cause of delays, although he did not say what was.

Long March 7 tests continued in August, when CASC reported that the low-temperature gas tank of the Long March 7 booster had successfully undergone a blast test.

Even more challenging than the article says. The article is concentrating on one weight class (which is understandable), but from what I see of the launchers, their design is "maxed out"... In other words, they already have strap-ons or multi-cores. To go any bigger (like Falcon 9H or Angara), they will need a new core.

The Long March-5 will have a payload capacity of 25 tonnes to low Earth orbits, or 14 tonnes to geostationary transfer orbit, about twice the current capacity, and could be a serious competitor to the U.S. Delta-4H.

The Long March-7 will carry up to 13.5 tonnes to low Earth orbit or 5.5 tonnes to sun-synchronous orbit at a height of 700 km. It will carry cargo craft for the planned space station. Its maiden flight should be next year.

China's Long March 9, the equivalent to the US SLS, first launch is set for 2028.

http://www.telegraph.co.uk/news/worldnews/asia/china/11279450/China-develops-new-rocket-for-manned-moon-mission.html


Li said that the Long March-9's diameter and height would be far greater than the Long March-5, while its thrust would be more powerful.

"We need to develop a brand new engine for it to make sure the rocket has sufficient thrust," he said.

Li Jinghong, a designer at the academy, said the rocket would not only be used for missions to the Earth's only natural satellite, but also for other deep space exploration projects.

The vehicle's diameter "should be eight to 10 metres", and its weight "at least 3,000 metric tonnes", he said.


The information on the Long March 9 rocket as reported in the Chinese press with a few more details.

http://www.ecns.cn/2014/12-08/145693.shtml


China is conducting preliminary research on a super-heavy launch vehicle that will be used in its manned missions to the moon.

"We are discussing the technological feasibility and requirements of the Long March-9, and research on the solutions to some technical difficulties have started," said Li Tongyu, head of aerospace products at the China Academy of Launch Vehicle Technology. "Its specifications will mostly be determined by a host of factors, including the government's space plan and the nation's overall industrial capability, as well as its engine's development."

The Long March-9's diameter and height will be much larger than those of the Long March-5, and its thrust will also be much stronger, he said.

"Our current launch vehicles, including the Long March-5, which is set to conduct its first launch soon, will be able to undertake the country's space activities planned for the coming 10 years, but for the nation's long-term space programs, their capabilities will not be enough," he added, emphasizing the necessity and significance of a super-heavy rocket.

"In addition, the cryogenic engine using liquid hydrogen fuel and liquid oxygen oxidizer (designed for the Long March-5) is not powerful enough for the Long March-9, so we need to develop a brand new engine for it to make sure the rocket has sufficient thrust."

Diesel is not non-polluting, and cryogenics do take a lot of energy to use (which would be non-polluting if they could use non-polluting energy sources)
Their rockets are no more non-polluting than anyone else who is not using solids.

If the latest report on the Long March rockets is true than the launch date has slipped another year to 2016.

http://usa.chinadaily.com.cn/epaper/2014-12/25/content_19167544.htm


Zhou Jianping, chief designer of China's manned space program, told Xinhua News Agency in an earlier report that the first launch of the Long March-7 and the cargo spacecraft will be around 2016, to serve the Tiangong-2 space laboratory, which is planned to be in orbit by the end of next year.


Lei Fanpei, chairman of China Aerospace Science and Technology Corp, said earlier this month in Beijing that in addition to the Long March-7, three other new types of rockets - including the Long March-5, a heavy-lift rocket that is more powerful than the Long March-7 - will also fly for the first time in the next two years.

A tantalizing glimpse into the factory producing the Long March 5 & 7.

http://www.ecns.cn/2015/01-06/149511.shtml


China's new generation carrier rocket industrialization base, embracing China's dream of becoming a leading space power, is located in Tianjin Economic Development Zone.

The base, with a total floor area of 3000 mu (200 hectares), meets all the requirements of rocket development and testing. Construction began in June 2008. Six years have passed since. The industrialization base now has production capacity for Long March V and Long March VII, two representatives of a new generation of launch vehicles.

"The greater China's rocket carrying capacity, the bigger the momentum of China's space industry," says Tao Gang, general manager of Tianjin Long March rocket manufacturer. "Current rocket carrying capacity cannot meet the actual needs of China's growing aerospace industry. That is the main reason for this industrialization base for the new generation of carrier rocket."

An all-system drill simulating the launch of a Chang Zheng-7 (CZ-7, or Long March-7) rocket is currently under way at the newly-built Hainan launch centre.

http://sinodefence.com/2015/01/27/cz-7-launch-drill-under-way-at-hainan/


It is understood that the all-system launch drill is the final and most important step in the CZ-7’s ground testing prior to its maiden flight, currently scheduled for April 2016. The mission will launch the first Tianzhou cargo spacecraft designed to resupply the future Chinese space station Tiangong. Chinese space planners hope that once its design matures the CZ-7 will eventually replace most variants in the current CZ-2, 3, and 4 series of launch vehicles, including the man-rated CZ-2F for Shenzhou missions.

It will also be the first launch taking place from the newly built Hainan launch centre, which began its construction in 2009. The new launch centre offers a range of advantages over the existing three inland launch centres in China. Its proximity to the equator (19 degrees north of the equator) gives rockets significant payload performance gain from the Earth’s rotation. The centre is located near the coast, allowing oversized rocket boosters and spacecraft to be transported via the sea. Used rocket stages can be dumped directly into the sea, with no danger of falling into any populated area.

China makes progress with its quest to build their generation of rockets - Long March 5

Chinese scientists have completed a ground test on the power system of the country's next-generation carrier rocket which may fly as early as next year.

Scientists test-fired the engines of Long March-5, which uses non-toxic and no-polluting liquefied propellant, on a ground facility to test "coordination and reliability" of the power system, the State Administration of Science, Technology and Industry for National Defense (SASTIND) said on Monday.

Again with the non-polluting propellant. Yes; it "uses" hydrogen which is non-polluting (if you ignore producing it), but it also uses diesel/kerosene. (post 28)
I wish they would be clear about it. But; they think kerosene is clean anyway. They made the same claim over 2 years ago (http://www.engadget.com/2012/07/31/chinas-new-liquid-oxygen-and-kerosene-fueled-rocket-engine-ligh/).

According to Wiki, their hydrogen engine is less than half the thrust of their kerolox engine. And it depends on which cores they use.

http://zeenews.india.com/news/sci-tech/china-to-carry-first-flight-of-new-generation-space-rocket_1559167.html


Beijing: China will soon conduct the first flight of its new generation 'Long March' space launch vehicle fired by newly developed 120 ton engine in a bid to tap the growing international commercial satellite market.

"A launch of the Long March 6 is planned in the middle of the year and it will use the newly developed 120-ton-thrust engine as its main propulsion," Tan Yonghua, president of China's Academy of Aerospace Propulsion Technology said.

"The Long March 7 and our most powerful rocket, the Long March 5, will make their first flights next year and they will also use the new engine," Tan, a deputy of the National People's Congress (NPC), told state-run China Daily on the sidelines of its session.

"This is the last test of Long March-5's power system before its maiden flight. It means China's utilization of hydrogen has entered the application process," Li Hong, dean of China Academy Of Launch Vehicle Technology, said.

The rocket's first flight is scheduled for April next year. And there's no stopping there, as scientists continue to design carrier rockets with ever higher payload capacities.

It makes me wonder if there's some confusion between LM6 and LM5-cz200 which seem to be basically the same rocket with different engines.

The rocket engine they will be using is the YF-100 according to this article (http://www.popsci.com/chinas-long-march-space-rocket-5-takes-another-big-step-forward). It will also be used on the LM6 and the LM7.

The article also has sketches of the different variations of the LM5 which will be used for payloads from 6 tons to 25 tons.

The article below has more information on the LM7.

http://www.popsci.com/next-generation-chinese-space-vehicles-begins-its-long-march-standing


The LM-7 is a mid-heavy weight, 600 ton launch rocket, similar to the SpaceX Falcon 9 rocket. It is likely to replace the man-rated Long March 2 rocket, which is currently used to launch China's manned Shenzhou space missions. However, the LM-7 is estimated to carry 13.5 tons (depending on booster rocket configuration) of cargo in low earth orbit, which is a 50% increase over the LM-2. Its 3.35 meter core diameter would allow it to carry most commercial payloads, as well as larger scientific payloads into sun synchronous orbits to observe space weather activity like solar flares.

It is all go for the Long March 7 to be launched next year. Also the LM-5 for next year and the LM-6 foe this year. This is good news as the launch of the Tiangong-2 space station as well as the cargo ship Tianzhou depends on them.

Nice picture of the LM-7 production line.

http://www.leonarddavid.com/china-long-march-7-booster-first-flight-2016/


It has been announced that China’s Long March- 7 booster has passed a joint assessment by the China Aerospace Science & Technology Corporation and China Academy of Launch Vehicle Technology.

The outcome of the appraisal, according to a June 18 report in China’s state-run news output, the People’s Daily Online, is that the technical condition of Long March-7 rocket production has been identified. The next stage focus will be placed on rocket production, assembly and testing of the launcher.

These items mean that the Long March 7 rocket is slated to make its maiden flight in 2016, according to the People’s Daily Online.

Now I am really confused. HELP!!! The latest report from China has the LM-5 maiden flight in 2017 with only a test flight next year.. If that is the case why has it got the cargo ship meeting up with Tiangong-2 in 2016. How will they get Tiangong-2 into space?

http://gbtimes.com/china/china-rocket-tests-mark-step-forward-space-station-plans


The Long March 5 has suffered a number of delays during its development, but progress is picking up, with a maiden flight set for 2017. The second successful separation test followed two crucial propulsion tests of the core rocket stage, which uses two YF-77 engines.

The Long March 5 is scheduled for a test flight next year and, being comparable to the Delta IV Heavy, will be one of the largest rockets in the world.



The medium-lift Long March 7 will launch the Tianzhou-1 robotic cargo spacecraft, which is designed to re-supply the future Chinese space station. The pair is due for launch in 2016, when Tianzhou-1 will rendezvous with the Tiangong-2 experimental space module.

Sorry, misunderstood.

I wonder if T2 really is 20 tons. I tried researching it farther, and all I got were words like "expected" and "speculation". A lot of discussions revolved around the fact that since it was a test for T3, that it would be the size of one of the modules. But, it turned out that it was the technology being tested and not necessarily the construction.
You even questioned (http://cosmoquest.org/forum/showthread.php?152373-China-Space-Station&p=2241221#post2241221) an article talking about the idea that T2 wouldn't be much more than the T1 in size.

Why receive a cargo vessel that is bigger then Tiangong 2. More logical to have Tiangong 2 more like Tiangong 3 and do all the tests on new technology like refueling and extended stay. Tiangong 2 then needs to be heavier and could be launched by Long March 7 rocket (reason for the delay to 2016?).

And I followed that up with my own reasoning between the confusion (http://cosmoquest.org/forum/showthread.php?152373-China-Space-Station&p=2254251#post2254251) of those figures.

Reports of the Chinese space program are shrouded in mystery and speculation. With all the different statements floating around, it's hard to tell exactly what is going on. I am only offering possible explanations.

I doubt it, but I wouldn't be surprised.
It might answer the question of why they would put a 20 ton load on a 25 ton rocket. It gives them a safety margin that they don't have to push it as hard as it needs to be. But; on the other hand, it's a risk to launch such an expensive payload on a test flight.

Just came across this article on the new Long March rockets from March. It also gives a reason for the slippage from 2015 (this year) to 2016 for the Long March 7. The other interesting information was all three rockets will use the same engine.

http://m.aviationweek.com/space/long-march-7-delayed-again-due-fly-2016

The latest schedule for the three rockets, which are under development together because they share airframe modules and engines, was given by Tan Yonghua, president of the Academy of Aerospace Propulsion Technology (AAPT). Tan is probably happy to discuss the matter because the Long March 7 delay is unlikely to be the fault of his organization. AAPT is providing the engines, which have long been confirmed as mature and ready for service.

“The Long March 7 and our most powerful rocket, the Long March 5, will make their first flights next year, and they will also use the new engine,” the China Daily quotes Tan as saying. The engine is the 120-ton-thrust YF-100. Its development was completed before 2012, when series production of the engine began. So it has been waiting at least three years for its first flight on one—any—of the new launchers. Long March 6 will provide the occasion.

I agree with your view. That is why the flight which was to be this year is now set for next year. They do not tell us what the problems are,

I am waiting for the first flight of the Long March 6 in September this year. If successful, it at least tells us the new engine (all 3 rockets LM5, LM6, & LM7 use it) is not the cause of the delay.

More details in spaceflight101 especially on the commonality between LM6 and LM5 and LM7.

http://www.spaceflight101.com/long-march-6---first-launch.html


The criticality in the maiden flight of the CZ-6 version also arises from the commonality between the new generation of Kerolox vehicles that is being implemented as a cost-saving measure and to accelerate the development of the new rockets. A number of components are common across the different variants of Long March 6, 7 and 5 including engines and rocket stage construction.

Long March 6 set out to demonstrate the YF-100 engine for the first time in a flight environment, also to be used on the boosters and first stage of the Long March 7 rocket and the boosters of the heavy Long March 5.

Picture
Photo: Weibo - 军报记者
Furthermore, the tanks and overall structure of the CZ-6 first stage is largely based on the larger Long March 5 booster for a simplification in the fabrication of the two rocket types that can share tooling and manufacturing techniques. The YF-115 second stage engine employed by the Long March 6 also finds use on the second stage of the CZ-7.

Given the large amount of commonality between the Long March 6 rocket and its bigger sisters, Saturday night's test flight will significantly affect the development of the CZ-7 and CZ-5 after actual in-flight data from the various components can be factored into analysis and flight/environment calculations. The Long March 6 launching on Saturday was outfitted with in-flight instrumentation for the collection of data beyond the normal launch vehicle telemetry to allow engineers to accurately assess the response of all components to the different flight environments.

Some more information on the LM11 is in the spaceflight101 report of the launch.

http://www.spaceflight101.com/long-march-11-first-launch.html


A technical document published while Long March 11 was still in development called for the vehicle to stand around 18.7 meters tall using a stack of three solid-fueled stages with an Auxiliary Liquid-Fueled Upper Module for precise insertion capability. Measuring 2.0 meters in diameter, the first stage is the largest solid rocket motor operated by China. The first stage is around nine meters long while the second stage measures three meters in length, sharing the first stage's diameter. The smaller third stage is around 1.4 meters in diameter and one meter long with the payload stack sitting atop, protected by a 1.6-meter diameter payload fairing.

The fourth stage is reportedly powered by a YF-50 engine using liquid propellants and providing precise insertion capabilities into a variety of orbits - an overall design sharing similarities with Europe's Vega rocket that also employs a powerful stack of three solid stages topped by a low-thrust upper module to finish the orbital insertion.

Photos of the CZ-11 rocket have shown that it uses an above-ground launch container in which it is stored and moved to the pad - not unlike the Russian-operated Rockot and Topol rockets.

The exact performance of the Long March 11 is unknown, some reports claim that it can deliver up to 1,000 Kilograms to a Sun-Synchronous orbit.

This is not about the Long March rockets but on the "father of Chinese rocketry", Qian Xuesen. How many realize that he is not only instrumental to the development of China's rockets but also a founding member of the rocket research group in California Institute of Technology (Caltech), as well as involved in the formation of the Jet Propulsion Laboratory (JPL).

http://news.xinhuanet.com/english/2015-10/03/c_134681947.htm


Marking the 60th anniversary of Qian's returning to his homeland from the U.S. in 1955, the exhibition titled "Qian Xuesen: a man of science and an inspiration to scholars," features numerous archives, documents and images of the scientist throughout his life and career.

"It is rare that one individual that can make such great achievements in two countries in one's life time," Dr. Thomas F. Rosenbaum, president of Caltech, one of the sponsors, said when opening the exhibition.

"If you look at Professor Qian, at what he used to do both in the U.S. and in China, (you) reflect the way that language of science can improve the future for humanity, not a particular country," he said.

Before returning to China, Qian spent two decades studying and working in the United States, and made seminal contributions in applied mechanics, aeronautical engineering and many other fields.

Qian was a founding member of the rocket research group in Caltech, not only involved in the formation of the Jet Propulsion Laboratory (JPL), but also making contributions to the victory of allied countries in the world anti-fascist war.

"The influence of Qian Xuesen was profound, who led the formation of JPL, and of course China's space program and missile program depended crucially on the contributions of the same man," Rosenbaum said.

This year should also see maiden flights of the next-generation Long March 5 and Long March 7 rockets. The largest Long March 5 rocket (CZ-504) is a 203.4-foot (62-meter) tall heavy-lift launch vehicle designed to be able to deliver up to 25 metric tons of payload to low-Earth orbit (LEO) and up to 14 metric tons to a geostationary transfer orbit (GTO). Weighing 810 metric tons, it is described as being the heaviest and most technologically challenging member of the Long March rocket family. The China Academy of Launch Vehicle Technology is carrying out final tests of this booster to prepare it for its first flight scheduled for September.

The 174.2 feet (53 meters) tall Long March 7 is a medium-heavy launch vehicle with a mass of 594 metric tons. It will be capable of launching nearly 13.5 metric tons to LEO and about 5.5 metric tons into a Sun-synchronous orbit (SSO). Although, this booster is designed to deliver satellites into space, its structure is based on the Long March 2F rocket employed for crewed missions. The date of the first Long March 7 flight hasn’t been disclosed yet.

Li said the tests were the riskiest and most sophisticated that China has ever conducted on its rockets and involved about 300 engineers. The tests' outcome will be used to improve the first mass-production rocket, which will be launched in September, he added.

China plans to launch 110 Long March rockets over the next 5 years.

http://www.globaltimes.cn/content/971568.shtml


A Chinese rocket scientist said Wednesday that 110 China-made Long March rockets will take to the skies over the next five years, as more models are developed.

Liang Xiaohong, member of the Chinese People's Political Consultative Conference National Committee and a former head of the China Academy of Launch Vehicle Technology, said the past decade witnessed a rapid increase in the number of Long March rockets launched.

From 2011 to 2015, 86 Long March rockets were launched, and from 2006 to 2010 the number was 48, Liang said before the country's political advisory body convenes its annual session.

Liang Xiaohong, former vice president of the China Academy of Launch Vehicle Technology (CALT), told state news agency Xinhua the super heavy lift rocket, known as Long March 9, will allow China to attempt an ambitious Mars sample return as part of its exploration plans for the Red Planet, and also to put people on the Moon.

A crewed lunar mission is an objective that China has not stated publicly, but is believed to be working towards and slowly mastering the techniques and technologies required.

Mr Liang says the Long March 9 will be nearly 10 metres in diameter, over 100 metres tall, and have a payload capacity of around 130 tonnes, rivalling the US’s Space Launch System (SLS) rocket.

The 3,000 tonne Long March 9 is still at the very early stages of development, and expected to make its maiden flight around 2030.

Liang, a member of the Chinese People's Political Consultative Conference (CPPCC), was speaking ahead of the opening of China’s annual parliamentary sessions in Beijing.

The sessions will see the adoption of the country's new Five Year Plan, which will include objectives for its state-run aeropsace industry.

Chinese rocket engine designers have started to develop next-generation engines that will propel the nation's future super-heavy rocket, which is tentatively called Long March 9, according to a senior rocket scientist.

"Engineers at my academy are researching and developing a 500-ton-thrust liquid oxygen/kerosene engine and a 200-ton-thrust liquid oxygen/liquid hydrogen engine that will be used on the future heavy-lift rocket," Tan Yonghua, president of the Academy of Aerospace Propulsion Technology and a national lawmaker, told China Daily on the sidelines of the annual session of the top legislature.

The Long March 7 rocket to be launched next month has departed for its launch base in Hainan on Sunday from north China's port of Tianjin.:clap:

http://www.globaltimes.cn/content/981912.shtml



It has taken researchers eight years to develop the medium-sized rocket, which can carry up to 13.5 tonnes to low Earth orbit, said Li Hong, director of the Carrier Rocket Technology Research Institute with the China Aerospace Science and Technology Corporation.

"The Long March-7 launch scheduled for late June will be of great significance as it will usher in China's space lab mission," said Yang Baohua, deputy manager of the company.

Professor Huang Jun at the Beijing University of Aeronautics and Astronautics told gbtimes last year that this new generation of Chinese launch vehicle series uses universal modularised design which can be easily combined into new rocket variants for various missions.

“The reliability and launch preparation time are improved and the launching cost will be lowered,” Huang said.

While China’s current Long March series rockets are fuelled by highly toxic hydrazine propellant, the new Long March 5, 6 and 7 launch vehicles mainly use a mix of kerosene and liquid oxygen to reach orbit.

The new propellant, also used by the SpaceX Falcon 9, provides greater specific impulse, with the by-products being water and carbon dioxide.

Here is pictorial confirmation the LM7 parts have reached Hainan Island to be assembled in Wenchang Satellite Launch Center.

http://spaceflightnow.com/2016/05/18/china-to-debut-new-rocket-and-spaceport-next-month/


This could be a banner year for China’s space program, with the debut of the Wenchang space center and the Long March 7 planned in June, followed by the maiden flight of the heavy-lift Long March 5 launcher from Wenchang before the end of 2016.

The Long March 5 rocket will loft up to 25 metric tons, or 55,000 pounds, to low Earth orbit, enough to place heavy modules in orbit for China’s planned space station. The heavy-lifter can put up to 14 metric tons, or nearly 31,000 pounds, into geostationary transfer orbit, the destination favored by most communications satellites.

That is roughly equivalent to the capacity of United Launch Alliance’s Delta 4-Heavy rocket, and two-and-a-half times China’s current lift capability.

The 2nd stage of the Long March 7, that was launched on June 25th on its maiden test flight, reentered the atmosphere and blazed through Earth’s atmosphere over the Western United States late Wednesday.

Darting across the skies of California, Nevada, Utah, Idaho and Colorado, the object disintegrated into numerous chunks before disappearing. The relatively slow speed of the fireball — it took nearly a minute to cross the sky — ruled out a natural origin, experts said.

The video above was captured by Matt Holt in Utah County, Utah.

The source of the unexpected sky show around 9:40 p.m. PDT Wednesday (12:40 a.m. EDT; 0440 GMT Thursday) was the second stage from China’s Long March 7 rocket, which took off June 25 on its maiden test flight, according to Jonathan McDowell, a scientist at the Harvard-Smithsonian Center for Astrophysics who tracks global satellite and launch activity.

http://gbtimes.com/china/chinas-heavy-lift-long-march-5-arrives-spaceport-debut-launch


The Long March 5 will become the country's largest ever rocket and will be used for constructing the future Chinese Space Station, launching the Chang'e-5 lunar sample return mission and the country's ambitious 2020 Mars mission.

The Long March 5 was transported to Wenchang on the island province of Hainan by the custom-built Yuanwang 21 and 22 cargo ships in a six-day journey from the northern port city of Tianjin, where the rocket was manufactured.

At over 50m high and with a diameter of 5m, the Long March 5 will have a mass at liftoff of around 800 metric tonnes, with the heaviest lift configuration capable of putting a 25 tonne payload into low Earth orbit or 14t to geostationary transfer orbit, greatly boosting China's space capabilities.

He Wei of China Aerospace Science and Technology Corporation (CASC) and overall designer of Long March 5 told CCTV that: "Compared with predecessor carrier rockets, the Long March 5s have made progresses by leaps and bounds in designing methods, designing tools, manufacturing and assembling procedures, paving the way and laying more solid foundation for future development of bigger carrier rockets."

http://gbtimes.com/china/china-set-become-great-space-power-launch-long-march-5


China’s space programme has long been regarded with doubt and suspicion over its intentions and the quality and origins of its technology. But China is set to demonstrate its ability to execute ambitious long-term plans for space and propel itself to the status of great space-faring nation.

At a new coastal launch centre on the southern island of Hainan, China is now all set to launch its largest ever rocket, and in doing so more than double its launch capabilities.

The 800-tonne, 5-metre diameter Long March 5 was rolled out to the launch pad this morning for launch next week. The heavy-lift launch vehicle is capable of lifting a 25 tonne payload to low Earth orbit, making it comparable to the most powerful active rockets in the world such as the Delta-IV Heavy, Atlas V and Ariane 5.

Being the first flight, the mission will be mainly a test and validation, carrying the Shijian-17 experimental satellite to geosynchronous orbit. And as with the debut of the breakthrough (yet smaller) Long March 7 in June, we can expect live coverage – another new development for China – around November 3, though date and time of launch has not been announced (an old habit).

But crucially the Long March 5 will allow the country to assemble its planned large space station – a long-term project set out in 1992 – as well as launch scheduled deep space exploration missions that highlight China’s expanding horizons.

These include the Chang’e-5 lunar sample return in 2017 and sending an orbiter, lander and rover to Mars in 2020.​

China’s Long March 5 rocket was rolled out to a Launch Pad on Hainan Island on Friday for the heavy-lifter’s inaugural flight next week, marking the last in a series of new rockets to be introduced by the Chinese.

Long March 5, China’s most powerful rocket, will be tasked with lifting the country’s future Space Station modules and expand China’s Geostationary launch capability.

Liftoff is officially set for ‘early November,’ with November 3 appearing to be the specific target according to various reports. The test flight is carrying to orbit the Shijian-17 experimental satellite that will complete a demonstration of electric propulsion for future use on Chinese Geostationary Satellites.

Long March 5 combines four liquid-fueled Kerolox Boosters with a two-stage cryogenic stack to lift up to 25 metric tons into Low Earth Orbit and 13,000 Kilograms to Geostationary Transfer Orbit – a performance comparable to the European Ariane 5 and American Delta IV Heavy Rockets.

Some background on the development of the LM-5 rocket.

http://www.scmp.com/news/china/article/2042590/chinas-30-year-long-march-its-biggest-ever-rocket-launch


The CZ-5 can lift 25 tonnes of cargo into low-earth orbit, two and a half times as much as the previous most powerful Long March rocket. To do that it required a whole new family of engines. The first stage of the CZ-5 consists of two large YF-77 liquid hydrogen/oxygen engines and the four boosters each have a pair of YF-100 kerosene/oxygen engines.

The rocket engine development and testing took place at a facility hidden in a valley to the south of Beijing. Residents living nearby, already used to ground tremors accompanied by deep, explosive blasts, detected a noticeable increase in testing activity in recent years.

According to official accounts, the first test-firing of the main engine was a failure, as was the second, third and fourth.

“Each failure dealt a heavy blow to the whole rocket team,” CZ-5 designer in chief Li Dong said in a documentary film released by China Central Television in April.

The first two prototypes exploded immediately after ignition, the others perished in flame and smoke due to fuel leaks.

“Some foreign experts said we would never be able to bring the engine from the drawing board to life,” Li said.

Andrew Jones on how China has been more open with the problems they have had with the LM-5.

http://gbtimes.com/china/china-opens-over-dramatic-long-march-5-launch


Thursday saw China successfully launch its new Long March 5, but neither the launch nor its decade-long development was anywhere as smooth as would have been hoped - and there has been a refreshing openness about these issues after liftoff.

The Long March 5 and its variants had been designed to allow China to construct a large space station and attempt complex deep space missions to the Moon and Mars. Failure would have brought serious delays to these projects.

Launch was initially set for 18:00 Beijing time from the Wenchang Satellite Launch Centre on the island province of Hainan, but the time was repeatedly pushed back.

The video above gives indication of the stop-start developments in the moments before liftoff, while below shows a dramatic call to suspend launch with the countdown at 60 seconds:

This report on the launch of the LM-5 gives more details of the history of the rocket and also details of the new upper stage Yuanzheng 2 (YZ-2).

https://chinaspacereport.com/2016/11/04/long-march-5-completes-maiden-mission/

The first launch of the Long March 5 (Chang Zheng 5, or CZ-5) rocket was originally scheduled for 18:00 CST (10:00 UTC) on 3 November 2016, but a string of technical glitches on the new rocket including liquid oxygen leaks, propellant tank cooling failure, and flight control problems caused four holds during the launch countdown. The launch time was postponed twice to 20:40 CST. The launch vehicle eventually lifted off at 20:43:13, slightly later than the originally scheduled launch window of 18:00—20:40.

Now we get information of the Long March 8.

http://gbtimes.com/china/china-launch-new-long-march-8-rocket-end-2018


China is aiming to launch a new Long March 8 rocket by the end of 2018 to fill a gap in the country's carrier rocket capabilities and commercial launch prospects, a top space official has said.

Li Tongyu, chief of carrier rocket development at the China Academy of Launch Vehicle Technology (CALT), told China Daily that the Long March 8 will use engines and other design aspects developed for the recently debuted Long March 5 and Long March 7 rockets.

According to a presentation at a United Nations Committee on the Peaceful Uses of Outer Space in February, the Long March 8 will be capable of sending a payload of about 7.6 metric tonnes to low Earth orbit, 4.5 tonnes to a sun-synchronous orbit, or 2.5 tonnes to geosynchronous transfer orbit.

The Long March 8 core stage will be 3.35m in diameter, as with the Long March 3 series and new Long March 7, and will utilise two 2m diameter solid-propelled boosters, according to Li.

http://gbtimes.com/china/long-march-5-chinas-most-powerful-rocket-rolled-out-second-mission

"China has rolled out its largest and most powerful launch vehicle, the Long March 5, in preparation for the rocket's second launch from the Wenchang Satellite Launch Centre.

Transfer of Long March 5 (Y2) from the vertical assembly building to the launch tower began at 08:30 local time (00:30 UTC) Monday, completing the 2.7 km trip around 11:00 am.

This second mission will see the 2.5 stage Long March 5 launch the Shijian-18 experimental telecommunications satellite to geostationary transfer orbit.

The launch window opens on July 2 and runs to July 5. The launch is, as with other launches from the new launch centre on Hainan Island, expected to be streamed live."

Andrew Jones on why the LM5 is crucial to China's long term plans.

In the article he also highlights the LM5B which will be used to launch the CSS segments to space starting in 2019. He expects two test flights of this version in 2018. One of them may carry a test capsule for a large, 20-tonne next-generation crewed spacecraft for deep space missions.

http://gbtimes.com/china/why-chinas-long-march-5-crucial-its-space-ambitions

"China's second launch of its Long March 5 rocket suffered an anomaly that resulted in the loss of the large, experimental Shijian-18 satellite on Sunday. The launch failure is a blow to China, as the heavy-lift rocket is both crucial to China's future space plans and a symbol of its technical prowess and commitment to space exploration.

The Long March 5 was developed to greatly boost China's launch capabilities, and has more than doubled the payload mass the country can deliver to low Earth and geosynchronous transfer orbits - and beyond.

The rocket's heavy-lift capabilities puts China in rarified company in the space world and allow it attempt missions only a few nations can, or ever have.

As such, it is key to the country's most ambitious space plans for the next five-to-ten years, both for human spaceflight, to low Earth orbit and, later, the Moon, and robotic space exploration, including interplanetary missions.

Getting the rocket flying again soon will be a priority, to keep the much-delayed space station and its Moon and Mars robotic programmes on track."

China's plans to get its heavy-lift Long March 5 rocket flying again are taking shape, with a heavy, experimental communications satellite being prepared for launch in 2018.

Yang Baohua, vice president of the China Aerospace Science and Technology Corporation (CASC), announced on Wednesday (Chinese) at an event in Beijing that a large Dongfanghong-5 satellite bus would be launched in 2018.

The first Dongfanghong-5 (DFH-5), designated as Shijian-18, was lost on the second flight of the Long March 5 on July 2, with the rocket and payload failing to reach orbit due to an apparent first stage propulsion issue.

Only the Long March 5, which successfully debuted in November 2016 and is by far China's largest and most powerful launch vehicle, is capable of lifting such a payload to a high orbit.

spaceflight101 contains details of the possible cause of the LM5 launch failure.

https://spaceflight101.com/china-progresses-toward-long-march-5-return-to-flight-via-yf-77-engine-testing/


Unconfirmed reports emerged in late November, citing sources within the Long March 5 Program Directorate, that the cause of the failure was pin-pointed. According to this unconfirmed information, the cause of the failure was a structural problem causing the turbopump rotor shaft enclosure cap within one of the YF-77 engines to break off and create a blockage within the propellant line.

Official comments made by Tianjin Long March Launch Vehicle Manufacturing Co. – producer of the CZ-5 and 7 rockets, confirmed that the cause of the failure was identified by late 2017 and design changes on the YF-77 engines were being implemented. Testing of the upgraded engine design began in mid-February at the Academy of Aerospace Propulsion Technology (AAPT) test facility near Xi’an. This marked the first of several YF-77 test firings planned in the first half of the year to a) verify the correct cause was identified for the CZ-5 Y2 failure and b) fully qualify changes made to the turbopump design in preparation for the next launch of the Long March 5.

It is understood that the Long March 5 Y3 mission will employ a set of newly built YF-77 engines implementing the changes identified in the wake of the failure. An existing batch of YF-77 units is to undergo inspections and modification followed by acceptance testing before being available for future flights.

China’s most powerful rocket will fly for the third time late this year, with success of the launch to be crucial to upcoming projects including a lunar sample return, space station module launch and a 2020 mission to Mars.

Speaking on the sidelines of the country’s annual parliamentary sessions in Beijing in early March, senior aerospace officials revealed to media — in piecemeal fashion — details of the return-to-flight of the Long March 5.

The launch will carry an experimental telecommunications satellite named Shijian-20, or ‘Practice-20’ in Chinese, based on a new, large DFH-5 satellite platform.

Zhang Hongtai, president of the China Academy of Space Technology (CAST), a developer and maker of satellites and spacecraft, stated that the Shijian-20 will increase the country’s high-throughput communications satellite capacity to 300 gigabits per second, up from the current 20 Gbps with the predecessor DFH-4.

After on-orbit technical verification of this first satellite, which he suggests would launch in November, Zhang states that future satellites using the DFH-5 platform will be able to supply capacity of 1 terabit per second.
