|China launched a new Baidou navigation satellite
(identified as Beidou-3G (1S) into orbit. The CZ-3CE was topped by a new
hypergolic bipropellant space maneuvering stage named Yuanzheng 1 (YZ-1).
The rocket's LH2/LOX third stage inserted YZ-1 and Beidou satellite into
a 194 x 25,307 km x 55 deg orbit. YZ-1 then fired its MMH/N2O4 fueled 490
N thrust engine YF-50 twice, first to raise the apogee to 35,785 km and
then, hours later, to circularize the orbit at 35,786 km, creating an inclined
