China launched two disaster monitoring satellites Saturday as officials
announced the country's next piloted space mission could occur before the
end of September, state media reported.

The two remote sensing birds blasted off at 11:25 p.m. EDT Friday (0325 GMT
Saturday). It was late morning Saturday at the Taiyuan launch site in
northern China.

The two-stage Long March 2C rocket released the two satellites in a sun-
synchronous orbit shortly after launch.

Expected to last more than three years, the satellites are the first
disaster monitoring spacecraft orbited by China, according to the Xinhua
News Agency.

Optical and infrared cameras can provide global coverage every two days,
Xinhua reported.

The satellites will be used to guide recovery efforts after large-scale
natural disasters, such as the deadly Sichuan earthquake that struck China
in May.

China relied on commercial imagery from U.S. and European providers to aid
early responders in the Sichuan earthquake.

Xinhua also reported Saturday that Shenzhou 7, China's third human
spaceflight, will launch between Sept. 25 and 30, several weeks earlier than
previously announced.

Three Chinese astronauts will launch atop a Long March 2F rocket from the
Jiuquan space base in northwestern China.

One of the crew members will leave Shenzhou 7's crew compartment to venture
outside in China's first spacewalk. Six military pilots have been selected
for the mission, with three prime astronauts and three backup crew members,
Xinhua reported.

The astronauts' identities have not yet been revealed.

Shenzhou 7 will come two years after China's most recent human spaceflight
in October 2005. China became the third nation to launch a person into space
during the Shenzhou 5 mission in 2003.
