China's first carrier rocket for commercial use is scheduled to make its maiden¹ flight in the first half of 2019, according to the China Academy of Launch Vehicle Technology (CALVT).

 

中国运载火箭技术研究院表示，国内第一枚商用运载火箭将于今年上半年首飞。

 

The rocket, named Smart Dragon-1 (SD-1), is the first member of the Dragon series commercial carrier rockets family to be produced by CALVT, as China accelerates the development of commercial space industry.

 

China's current carrier rockets all belong to the Long March family.

 

CALVT launched the design and development of the small-scale, solid-propellant rocket in Feb. 2018. The SD-1, with a total length of 19.5 meters, a diameter of 1.2 meter, and a takeoff weight of about 23.1 tonnes, is capable of sending over 150 kg payloads to the solar synchronous² orbit at an altitude of 700 km.

 

Since the rocket is designed especially for commercial use, its cost for sending payloads per unit into orbit is lower than that of similar rockets in the international market, according to CALVT.

 

It takes only six months to produce one such rocket, and 24 hours to prepare for the launch. It can be used for launching either single satellite or multiple satellites at a time.
