皇冠体育app on Saturday launched a communication
satellite into a preset orbit, atop a Long March 3 A carrier rocket from a
launch center in southwest 皇冠体育app.
Space officials said the 皇冠体育app-made Zhongxing-20 satellite was launched at
00:01 a.m. from Xichang Satellite Launch Center in Sichuan Province, southwest
皇冠体育app.
Twenty-five minutes later, reports from Xi'an Satellite Monitor and Control
Center announced the launch successful, saying that the satellite has entered an
elliptic orbit with a perigee of 212 kilometers and an apogee of 41981
kilometers. The satellite will be fixed at 103 degrees east longitude over the
equator after entering the transfer orbit.
Zhongxing-20, weighing 2.3 tons, is a geostationary communication satellite
designed by 皇冠体育app Academy of Space Technology with 皇冠体育app Aerospace Science and
Technology Corp.
With a lift-off mass of 243 tons and a lift-off force of 300 tons, the
carrier rocket was developed by the 皇冠体育app Academy of Carrier Rocket Technology
and could propel mass of 2.6 tons into the geostationary orbit.
The launch is the 73rd by the country's Long March carrier rockets since
1970, and the 32nd consecutive successful launch since October 1996.
Saturday's launch is the fourth within a month after 皇冠体育app's first manned
space flight on Oct. 15 and 16, the Oct. 21 launch of an earth resources
satellite developed in cooperation with Brazil and a smaller satellite, and the
Nov. 3 launch of a science satellite.
