PARIS — China Aerospace Science and Technology Corp. is likely to resume flights of its heavy-lift Long March 5 rocket this year, said Xing He, executive vice presidentof China Great Wall Industry Corp., a subsidiary of China Aerospace Science and Technology Corp.

“The exact cause of the failure has been pinpointed,” He said Sept. 10 at the World Satellite Business Week conference here. A launch date has not been selected but will “probably be in this year,” He said.

The second launch of China’s Long March 5 carrying Shijan-18, an experimental communications satellite, failed in July 2017.  China’s State Administrator for Science, Technology and Industry for National Defense attributed the failure to a turbopump in one of the YF-77 first-stage engines.

If China does conduct a Long March 5 launch in 2019, it likely will be late in the year. First the rocket would travel to the launch site via cargo ships, a process that takes roughly two weeks. During the two previous Long March 5 missions, preparations at the launch site took another couple months.

China’s space industry has conducted 13 launches in 2019, compared with a record-setting 38 launches in 2018, He said.

In addition to launching large communications, remote sensing and exploration satellites, Chinese rockets are catering increasingly to small satellite customers. In 2018, China Great Wall Industries “successfully delivered 35 small satellites into orbit” for domestic and international customers, He said. “This is our opportunity,” he added.

China was barred from launching many large satellites due to U.S. International Traffic in Arms Regulations (ITAR), He said. Those regulations prevent the export of many satellites and satellite-related components.

“So we are focusing quite a lot on small satellites, which are beyond the control of the ITAR regulations,” He said. “This year we found more and more opportunities in China as well as with our customers all around the world.”

China will launch small satellites for traditional customers as well as small satellites destined for large constellations, He said. China will offer small satellite rides on its large rockets as well as two commercial small launch vehicles companies are developing for small satellites, He said.

China also is developing a commercial communications constellation with more than 800 satellites, which will fly on Chinese rockets. “We are very determined to launch” the constellation, He said.

The final configuration of the constellation, including the exact number of satellites, has not been decided, He said. The constellation’s design is likely to be completed by the end of the year, he added.
