China will launch test flights for the next two space rockets in its Smart Dragon series meant for commercial use in 2020 and 2021.

Axar.az reports citing Reuters.

The release of the flight schedule by China Rocket Co, a unit of state-owned China Aerospace Science and Technology Corp, comes two months after the firm’s first reusable rocket, the 23-tonne Smart Dragon-1, delivered three satellites into orbit.

China envisions constellations of commercial satellites that can offer services ranging from high-speed internet for aircraft to tracking coal shipments. Reusable designs will enable frequent rocket launches and help keep costs down.

The solid-propellant Smart Dragon-2, weighing about 60 tonnes and with a total length of 21 meters, will be capable of sending 500 kg payloads into orbit at an altitude of 500 km (310 miles), Xinhua said. It is expected to conduct a flight test next year.

At about 116 tonnes and with a length of 31 meters, the Smart Dragon-3, set for a test flight in 2021, will be capable of sending 1.5 tonne payloads into orbit, Xinhua added.
