The Long March-5 is part of China's next generation rockets, and represents a landmark in the country's space program. Let's take a brief look at some of the other rockets, and what they are capable of.

The Long March-2F rocket is specially designed for China's manned space missions.

Last month, it carried the country's space lab, Tiangong-2, into orbit.
Improvements were made through the years. The most recent one is the installation of the domestically-developed Beidou Navigation Satellite System.

"The Beidou system will improve the accuracy of calculation during orbiting. Cause now there is one more information source," said Zhang Zhi, Chief Designer of Long March-2F.

Development of the Long March-3 was completed in 1984. It is the exclusive carrier of China's moon exploration spacecraft, and is well received by the international market.

The Long March-7 carrier rocket is a medium-sized rocket. It uses liquid propellant, and can carry a load of up to 13.5 tonnes to low Earth orbit, a significant improvement from the past.

"Take one index for example. The specific impulse of its engine, which measures the efficiency of rockets, is 15 percent higher than other ones," said Liu Zhangguo, Chief Designer of Long March-7.

The Long March-11 is a solid propellant rocket. It is designed to meet the need of rapidly launching satellites in case of emergencies or disasters.

"We now only need 24 hours or less to prepare for a launch. The Taurus rocket from the US needs 72 hours," said Yang Yiqiang, General Director of Long March-11.

The family of Long March rockets have carried out over 200 missions though the decades, yielding a success rate of over 95 percent.
