A week after the launch of the first lunar orbiter, the
government Tuesday announced the building of a new family of rocket
launchers and a launch center.
The Long March 5 carrier rockets will be made in the northern
coastal city of Tianjin while the new launch center will be located
in the southernmost province of Hainan.
The next-generation rockets will be able to carry up to 25 tons
to near-Earth orbits, up from the current 9 tons; and 14 tons to
geosynchronous orbits, up from 5 tons. The diameter will be
increased to 5 meters from 3.35 meters.
They are designed to launch space stations or heavyweight
satellites, which the current Long March 3-A rockets cannot
handle.
"They are expected to meet the demands of space technology
development and peaceful use of space for the next 30 to 50 years,"
Wu Yansheng, president of China Academy of Launch Vehicle
Technology, said yesterday at the groundbreaking ceremony of the
base.
"It will also give China the same launch capabilities as
developed countries," Wu said, which means the nation can be as
competitive in the lucrative international commercial launch
market.
Research and tests on key technologies of the new rockets have
been completed, the academy said in a statement.
Complementing the rocket-building base will be the new launch
center at Wenchang.
Insiders said Tianjin was chosen because its location by the sea
can facilitate the maritime transportation of the new rockets -
which are too big to be transported by rail to any of the current
three launch centers in Gansu, Shanxi and Sichuan provinces - to
Hainan.
The manufacturing base in Tianjin is expected to cost several
billion yuan but neither the academy nor the Tianjin municipal
government would reveal the exact amount.
As the launch center in Wenchang will not be ready until 2012,
the new generation rockets will not blast off before 2013. Earlier
reports suggested that the Chang'e II and III were likely to lift
off atop the new carrier rockets.
The indigenously developed Long March carrier rocket series have
been launched 103 times - including for the liftoff of Chang'e I
last week - since their debut in April 1970.
Between April 1970 and October 1997, there were seven failures
in 49 launches, according to a 1998 issue of Aerospace China
magazine. Since 1997, the success rate has been 100 percent.
