Re: china manned space - news and views

Good News. Heavy duty boosters are needed to travel to the moon. I am hoping that China sends a woman astronaut so that China will still get First woman on the moon lol.

Not wanting to spoil your party AGAIN, but after all its effort on the last 40 years, china is still 4 years away from launching a 25t LEO rocket (Long march 5). Saturn V was 120t LEO. Not saying that they cant, but they still have a long way to go before they reach that goal.

Hmm .... and the point of your post is ? Which part of siegecrossbow post led you to think he didn't know China's moon mission will be a 'long' and challenging one ?
Perhaps feeling a bit sour on Aviation Week indicating China is starting a moon project ?

Well given the fact that China is acknowledging research in this area I am pretty certain that we'd see progress earlier than we would expect. Keep in mind that the Chinese space program uses a minute fraction of NASA's budget and already achieved spacewalk within years of the first manned mission. Keep in mind that no one expected China to shoot down satellites and intercept missiles midstage until China actually accomplished them .

Following your logic, the same also can be said of the european space effort. After 50 years of space effort, ESA is still far behind in its space endeavour, managing only to put a roughly 20 ton payload into LEO.

The thing is why would you want to built a Saturn V sized rocket to launch your satellites/probes when much smaller rockets can do the job?

China successfully launches fifth satellite for its own global navigation network


The fifth orbiter into space, as part of its satellite navigation and positioning network known as Beidou, or Compass system, is launched on the Long March 3I carrier rocket at Xichang Satellite Launch Center in Xichang, southwest China's Sichuan Province, on August 1, 2010. (Xinhua/Du Cai) (zhs)

XICHANG, Aug. 1 (Xinhua) -- China successfully launched its fifth orbiter into space at 5:30 a.m. Sunday, as a part of its indigenous satellite navigation and positioning network.

The satellite was launched from the Long March 3I carrier rocket.

It is the 126th flight for the country's Long March series of rockets.

The satellite will join another four satellites in orbit to form a network that will eventually consist of 35 satellites.

The system, code named "COMPASS", is a crucial part of the country's space infrastructure for providing navigation and positioning services in transportation, meteorology, petroleum prospecting, forest fire monitoring, disaster forecast, telecommunications and public security among others.

China started building its own satellite navigation system to end its dependence upon the U.S. GPS system in 2000, when it sent two orbiters as a double-satellite experimental positioning system.

The system is designed to provide navigation, time and short message services in the Asia and Pacific region before 2012 and will be capable of providing global navigation services by 2020.

Is Compass system operational now ? if it is the case, how good it is compared to GPS ?

Beidou 2 will be available for commercial applications in the Asia-Pacific region in 2012 and we can find out how it matches up against the GPS then, assuming that the world doesn't end . It will become a true "global positioning system" by 2020, when all 60 satellites are launched.

Not 60, but 35, according to the article:

Re: Chinese Satellites

Another 'YaoGan' launched one week after the 'Beidou'.
The highlight for a busy second half 2010 for Chinese launches should be another moon mission in October.

"China launches military satellite YaoGan Weixing-10
August 9th, 2010 by Rui C. Barbosa

Continuing what is expected to be a launch surge for the second half of 2010, China has launched a new remote sensing satellite on Tuesday, the sixth Chinese launch this year. YaoGan Weixing-10 was launched via a CZ-4C Chang Zheng-4C (Long March) launch vehicle at 06:49 local time on August 10 from the Taiyuan Satellite Launch Center.

Chinese Launch:

According to the Chinese media, the new satellite is intended for “scientific experiments, land survey, crop yield assessment, and disaster monitoring.” As was the case for previous launches of the YaoGan Weixing series, Western analysts believe this class of satellites is being used for reconnaissance and military purposes..........."

Re: Chinese Satellites

this actually happened a few day ago, but here it goes. China launches new mapping satellite

Please, Log in or Register to view URLs content!

JIUQUAN, Gansu, Aug. 24 (Xinhua) -- China successfully launched a mapping satellite, "Mapping Satellite - I," from the northwestern Jiuquan Satellite Launch Center at 3:10 p.m. (Beijing time) Tuesday.

The satellite, which was launched on a Long March 2-D carrier rocket, had entered into the preset orbit, according to the center.

The satellite, developed by a company under the China Aerospace Science and Technology Corporation (CASC), would be mainly used to conduct scientific experiments, carry out surveys on land resources, and mapping, said a statement on the Ministry of National Defense website.

The remote sensing information and test results from the satellite would promote the country's scientific research and economic development, said the statement.

The launch was the 128th for China's Long March series of rockets since April 24, 1970, when a Long March-1 rocket successfully sent the country's first satellite Dongfanghong-1 into the space.
