Changzheng 7 uses gas and liquid oxygen as its fuel so that there is a blue tinge in its orange-colored flame.
The new fuel is free of toxin or environmental pollution. In addition, it provides 60% more thrust.
Changzheng 7 is of the same size as its predecessors, but its four boosters are 27 meters long, nearly twice as long as its predecessors’.

Moreover, it is heavier with a takeoff weight of 600 tons, in which 90% is fuel.
Therefore, with better fuel, more powerful boosters and other new technologies, Changzheng 7 is able to send 13.5 tons to near-earth orbit, much heavier than the 8.6 tons that its predecessors are able to send.

According to Hu Leimin, an engineer at its Wenchang launch site, Changzheng 7 is a brand new rocket that has used lots of new technologies.
Its control system alone uses 143 items of new artificial intelligence software.

The rocket is waterproof so that unlike all other rockets in service, it can be launched in rain.
Its liquid oxygen tank has a heat isolate layer 10 mm thick of extremely low weight to maintain its surface temperature above 0℃ in spite of the minus 183℃ low temperature of the liquid oxygen.

Go to Mars by 2020

China wants to reach Mars by 2020, according to the chief designer of lunar and Mars missions for the CNSA. The top official opened up about the agency's plans for planetary exploration and future collaboration.

Since launching its first manned mission in 2003, China has sent up an experimental space station, the Tiangong 1, staged a spacewalk and landed its Yutu rover on the moon.

Its second space station, the Tiangong 2, is due to be slung into space in September this year.

Space program authorities said the spaceship's landing on the vast Inner Mongolian steppe keeps China on schedule to place its second space station into orbit later this year. dailymail
