The liquid of low temperature mainly uses combining of liquid oxygen and liquid hydrogen

The data suggests that the fuel of liquid fuel carrier rocket contains the liquid of normal temperature, there is also the liquid of low temperature.The liquid of low temperature mainly uses combining of liquid oxygen and liquid hydrogen, the clean environmental protection is current main current, but the low temperature carrier rocket technique request is high, the whole world only China, the United States, Russia, France and Japan own the carrier rocket technique of the low temperature motor.
The P GSAT-5 satellite weighs about 2310 kilograms, is the biggest communications satellite that India develops.Because the star is weight is too big, India exclusively carries on to the carrier rocket modification to adapt to a satellite weight.Print a dimension research to organize the original plan shoots this communications satellite on the 20th of this month, but because Russia develops of the low temperature motor appear to leak trouble, shoot be postponed till the 25th.
