Private companies want to launch reusable space rockets in 2020.

China has plans to launch reusable space rockets to compete with the likes of SpaceX and Blue Origin.

The Chinese Aerospace Science and Technology Corporation (CASC), the leading builder of Chinese space launch rockets, announced that its Long March (CHang Zheng in Chinese) LM-8 space rocket will launch in 2020.

Like the SpaceX Falcon and Falcon Heavy, the LM-8’s first stage will be reusable, using leftover fuel to land vertically. This shouldn’t come as a surprise, given that CASC has previously promised to make all its rockets reusable by 2035.

REPEAT LONG MARCHES

The LM-8 is a medium-sized space launch vehicle, capable of carrying 7.7 tons to low-earth orbit. It shares the same first stage core as the larger Long March 7 (which is China’s newest man-rated rocket), but compared to the Long March 7, it has only two K2 liquid rocket boosters. Once the LM-8’s second stage separates to enter orbit, the LM-8’s first stage will descend back to the ground by carefully burning remaining fuel to maneuver onto the landing pad, with the aid of grid fins. In the last moments of descent, landing struts will unfold from the bottom of the rocket to ensure a smooth touchdown. The boosters will separate and parachute back to the ground.

LM-7
The first Long March 7 flight took off from Wenchang, Hainan Island on June 25, 2016. It tested new technologies in orbit, like space debris removal, satellite refueling, and China’s next generation of manned spacecraft.

The tech LM-8 shares with the Long March 7 could mean that the LM-7—and other larger Chinese space launch rockets—could be retrofitted with resusablity. Additionally, CASC is planning to test grid fins on a Long March 4B rocket next year to refine the technology. Test launch of a reusable, smaller Long March 6 rocket is planned for 2020. Success in these tests will fit into CASC’s plan to make all its Long March rockets—from the super heavy “moon rocket” Long March 9 to the Long March 6—reusable by 2035.

NEW LINE ROCKETS
Linkspace’s New Line 1 rockets, built for launching microsatellites of up to 441 pounds in size, will have a reusable four-engine first stage. Future New Line models will be completely reusable.

This development is just one step in private Chinese companies’ larger path toward a reusable space launch market. Linkspace’s New Line 1 rocket, which will also land vertically via its reusable first stage, has plans for a 2020 flight. And CASC and its rival CASIC both plan to have their spaceplanes flying in 2020.
