LM-4B Launches GF-7 and 3 Other Satellites into Orbit

A LM-4B launch vehicle lifted off from the Taiyuan Satellite Launch Center at 11:22 Beijing time on November 3,2019,successfully launching the GF-7satellite,part of a major project of the China High-definition Earth Observation System(CHEOS)into its preset orbit.Three other satellites launched with GF-7 together were developed by the Shanghai Institute of Satellite Enginee ring.

LM-3B Successfully Launched APSTAR 7

At 18:27 Beijing time on March 31, China put theAPSTAR 7 satellite into its preset orbit by a LM-3B launch vehicle from the Xichang Satellite Launch Center. 26 minutes after the lift-off, the satellite separated with the rocket carrier and entered precisely the geostationary transfer orbit with a perigee of 209km, an apogee of 50419km

Concrete Progress Made on LM-7 Development

It was announced recently that important progress had been made on the development of the LM-7 launch vehicle. Assembly welding of the booster oxidizer tank for propulsion system test-firing, the first structural product of LM-7, has been performed at Capital Aerospace Machinery Corporation, CALT. The 2.25m diameter oxidizer tank is only 0.17cm in thinness in the thinnest area and is nearly 13m in length increased from the current 4.5m, which is the
