Testing of new rocket underway
China Daily, November 19, 2015

China is conducting tests on its largest and most powerful rocket, the Long March 5, at the Wenchang Satellite Launch Center in Hainan province, with plans to make the first launch before the end of next year, a senior space official said.

"Engineers are testing whether the rocket's various systems can work well with the Wenchang center, and after the tests are done successfully, the Long March 5 will perform its first flight by the end of next year," said Liu Tongjie, deputy head of lunar exploration and space programs at the State Administration of Science, Technology and Industry for National Defense, which oversees China's space activities.

The Long March 5 is the most sophisticated rocket that Chinese designers have developed, Liu told a news conference on Tuesday in Shenzhen, Guangdong province, where the administration opened a weeklong space exhibition on Wednesday. He added that the rocket is designed to conduct various missions.

Long March 5, the nation's next-generation heavy lift launch system, is nearly 57 meters high, with a diameter of 5 meters. With a liftoff weight of around 800 metric tons, it will have a maximum payload capacity of 25 metric tons in low Earth orbit and 14 tons in geosynchronous transfer orbit, roughly comparable to the capacity of the United States' Evolved Expendable Launch Vehicles, such as the Delta IV and Atlas V.

The rocket will use liquid oxygen/kerosene and liquid oxygen/liquid hydrogen as propellants for its engines, which means the gigantic craft will be more environmentally friendly than previous designs, its developers said.

The Long March 5 will be used to launch large lunar probes and the manned space station that China plans to send into orbit around 2020.

In addition to the Long March 5, China is developing the smaller Long March 7, whose maiden launch is also set for next year at Wenchang. It will replace the Long March 2 and Long March 3 in commercial launch service, and will be tasked with sending China's cargo spacecraft to the space station, according to the China Academy of Launch Vehicle Technology.

Did they get their date wrong. End of next year? Shall be end of this year ,right? Tiangong - 2 are waiting for this rocket in 2016 and if end of next year is true. That means Tiangong 2 will delay to 2017. And so as Lunar moon mission 2. What is wrong with CNSA? President Xi shall give these conservatives a earful. Any delaying of this rocket will delay all other Chinese space project. It cannot be delay anymore. The head shall roll if end of next year launch date is true.

End of next year is correct.
Tiangong-2 is the back up copy of Tiangong-1. It will also be launched next year.

Tiangong 2 weight at least 18tons. Without CZ-5, how is it going to be launched by next year?

I think there is some changes that caused some confusion. I believed Tiangong-2 is the same as Tiangong-1 with some modifications.

 

[Beast]

I think there is some changes that caused some confusion. I believed Tiangong-2 is the same as Tiangong-1 with some modifications.

I think its due to desperation, Tiangong 2 suppose to be a bigger space capsule mostly similar to the main core of future space station. By making it as small as Tiangong-1. It will delay China future space station further. It may test out some future system but not able to do close simulation of future space station. China shall pour billion at all cost to hasten this CZ-5. I dont know what's wrong with the leadership thinking. They seems do not know what is important or not. CZ-5 already has many delay. The leadership for this project shall be shot.

Well, Tiangong-2 has always exists. It is common practice in China that they built two identical system, one is the backup. Like Chang'e 2 is back up of Chang'e 1, Chang'e 4 is backup of Chang'e 3, and Chang'e 6 is Chang'e 5 backup.
I think what happen is this, originally(1st plan) you have Tiangong-1, 2, 3 and then the main module for the space station.
When Tiangong-1 is successful, there is talk of not going for Tiangong-2(backup of Tiangong-1) and convert it into space station cargo craft. And rename Tiangong-3 which is bigger into Tiangong-2. This is 2nd plan.
But the delay of LM-5 cause a problem to 2nd plan.
Therefore, Tiangong-2(backup) is revert back as Tiangong-2 again(1st plan). And the Tiangong-(3 or 2) of 1st and 2nd plan respectively is cancelled.
In other word, the original plan is to have more intermediary stages of increasingly bigger space station, but the delay of the LM-5 cause one of the intermediary stage to be cancelled. The schedule of the space station remain the same.
I am not sure if I am making any sense, but that is the best I can explain it.

China has launched the first satellite for the Southeast Asian country of Laos on a Long March 3B rocket from the Xichang Satellite Launch Centre.

Laosat-1, which was designed, developed and delivered on-orbit by China, blasted off from Xichang in Sichuan Province at 16:07 UTC Friday (00:07 Beijing time on Saturday, November 21).

29 minutes after lifttoff the satellite had separated from the rocket upper stage and deployed its solar panels. The launch was declared successful at 16:44.

LaoSat-1

The satellite is designed to provide communication links for government work, television transmission and a range of telecommunication applications in the mountainous, heavily forested country.

“The launch of the satellite by China is a special gift to Laos to mark the 40th anniversary of the Lao People's Democratic Republic on December 2,” the Laotian Minister of Posts and Telecommunications Hiem Phommachanh told national media ahead of launch.

Laosat-1 will operate in a geostationary orbit at 128.5° East, a slot reserved for Laos. The expected lifetime is 15 years, with 14 C band and 8 Ku band transponders for various communication services.

Mr Heim added that Laos is very proud to have its own satellite for the purposes of socio-economic advancement, which will be an important source of income for the country.

A number of representatives from Laos travelled to the launch site in Sichuan to witness thelaunch and preparations.

Laos signed a contract for Laosat-1 with the China Great Wall Industry Corporation, which deals with China's international space industry customers.

The Laos National Authority for Science and Technology will operate the satellite once operational in its designated orbit.

LaoSat-1 is based on the Dongfanghong series of satellite platforms, designed and developed by the China Academy of Space Technology (CAST). Sources state either a debut DFH-3B or a DFH-4S was used.

The Long March-3B rocket, currently China's most powerful active rocket, was developed by China Academy of Launch Vehicle Technology (CALT).

China's heavy launch schedule

Friday's LaoSat-1 launch was China’s 15th in 2015, following missions involving four Beidou global positioning satellites, the Gaofen-8, Gaofen-9 and Yaogan Weixing-27 earth observation satellites, a classified ka-band communication test satellite, the next-gen Long March 6 debut which lofted 20 small satellites, and the maiden flight of the solid-fuelled Long March 11.

In October Jilin-1, China's first self-developed commercial remote sensing satellite, APSTAR-9, developed and launched on behalf of a major regional satellite fleet operator, and the Tianhui-1C Earth observation satellite were put into orbit.

Early November saw the launch of the Zhongxing-2C military communications satellite from the Xichang satellite launch centre, followed by the lofting of Yaogan-28 from the Taiyuan Satellite Launch Centre in Shanxi Province, North China.

In December China will launch its DAMPE probe to hunt for dark matter.

The launch was the 217th of China’s Long March rocket families. The first took place in April 1970, when a Long March 1 rocket put China’s first satellite, Dong Fang Hong-1, into orbit.

Return to human spaceflight, rocket debuts in 2016

After a busy 2015, China's space program will attempt to make giant strides in its rocketry capabilities and space station plans next year.

China will make a return to human spaceflight with its first crewed space mission since 2013. Shenzhou-11 will liftoff from Jiuquan and will dock with China’s upcoming second space lab, Tiangong-2, which will be launched in advance of the taikonaut mission.

2016 will also see the new heavy-lift Long March 5 and medium-lift Long March 7 rockets make their debut launches. The two are designed to launch and service China’s future space station, as well as perform a lunar sample return mission in 2017.

Along with the dark matter-seeking DAMPE probe, China will launch three further scientific satellites within the next year to perform quantum science experiments, research space life science, and observe black holes, neutron stars and other phenomena.

In October Chinese state media revealed discussions on potential deep space exploration, including missions to Mars, Jupiter, asteroids, and, in the longer term, a crewed deep space mission.

Construction of China's mega radio telescope enters final stage
Source:Xinhua Published: 2015-11-22 10:06:47

Chinese scientists on Saturday tested the installation of the "retina" of the world's largest ever radio telescope to be completed in September next year.

Technicians lifted a 30-tonne source cabin of the Five hundred meter Aperture Spherical Telescope - or FAST - above a half-finished dish-like reflector measuring 500 meters in diameter and 1.6 kilometers in perimeter.

Once completed, the cabin, home to a feed source which collects signals from the universe, will be suspended 140 to 160 meters above the reflector made up of 4,450 panels.

Each panel is an equilateral triangle with a side length of 11 meters, and has cables fixed to the back of it so that it could adjust angles and positions in synchronization with the source cabin, which is driven by cables, servomechanisms in additional to a parallel robot as a secondary adjustable system.

"If you compare the FAST to an eye, then the feed source is its retina," said Sun Caihong, a chief engineer with the FAST program, "All signals we collect eventually comes here."

Sun said control of high-precision and long-distance movements of the source cabin using steel cables had been a serious challenge for experts, but they managed to narrow down maximum error to less then 10 millimeters.

"This is one of our greatest innovations," he said.

Construction of the FAST began in March 2011 with an investment of 1.2 billion yuan. Upon completion, the telescope will be the world's largest of its kind, overtaking Puerto Rico's Arecibo Observatory, which is 300 meters in diameter.

It will also be 10 times more sensitive than the steerable 100-meter telescope near Bonn, Germany.

Unlike optical telescopes used to observe the universe by visible light, a type of electromagnetic radiation, radio telescope operate in the radio frequency portion of the electromagnetic spectrum where they can detect and collect data on radio sources.

The key science goals of FAST are based on observables between 70MHz and 3 GHz, including the 21 cm HI hyperfine structure line, pulsar emissions and radio continuum.

Earlier reports said it will enable astronomers to jumpstart many science goals. For example, they could survey natural hydrogen in distant galaxies, detect faint pulsars, look for the first star shining, or even hear possible signals from other civilizations.
