The first step in China’s latest mission to the moon is the Long March 3B rocket that is carrying the Chang’e 3. With four booster rockets, it is China’s most powerful carrier rocket so far.

A Long March-3B carrier rocket was transported from Beijing on October the 27th, arriving at the Xichang Satellite Launch Center in early November. This mission is the 25th launch of the Long March-3B, which is the most powerful launch vehicle in the Long March fleet.

According to Cen Zheng, rocket system commander-in-chief of the mission, the carrier rocket is more than three meters in diameter, 56.4 meters high and weighs three thousand seven hundred and eighty kilograms. Engineers have incorporated modern high-precision guidance and control technologies, multiple narrow window launches, transmission system for remote sensing and reduction of the rocket’s deadweight into the rocket.

The Long March-3B has the Long March-3A as its core stage with four liquid boosters strapped on the first stage. With a launch capability of 5,000 kilograms, it is dedicated for launching heavy communications satellites like the Chang’e 3.
