China Landspace's Zhuque-3 Rocket Achieves Successful 60-second Hopping Flight

China commercial space firm Landspace has successfully conducted the first VTVL test for its reusable stainless steel rocket powered by methane-liquid oxygen.

Chinese launch startup Landspace executed its first vertical takeoff, vertical landing (VTVL) with a reusable Zhuque-3 VTVL-1 test article at 3:00 a.m. Eastern (0800 UTC) on Friday, Jan. 19, 2024, via a launch and recovery site from Landspace facilities at the Jiuquan spaceport in Inner Mongolia.

The methane-liquid oxygen test article reached an altitude of around 350 meters during its roughly 60-second flight before setting down in a designated landing area. The landing had an accuracy of about 2.4m and a landing speed of about 0.75m/second, according to Landspace.

The test is part of the development of the stainless steel Zhuque-3 rocket first announced in November 2023. The company is aiming for the first flight of Zhuque-3 in 2025. The company earlier planned to execute this first VTVL test last month.

The two-stage Zhuque-3 will be 4.5 meters in diameter and have a total length of 76.6 meters. Mass at liftoff will be about 660 tons and be powered by nine Tianque-12B engines. Payload capacity to LEO will be 21,000 kilograms when expendable. It will carry up to 18,300 kg when the first stage is recovered downrange, or 12,500 kg when returning to the launch site. 

China’s reusable rocket race

The Zhuque-3 VTVL-1 test follows similar “hop” tests conducted by fellow Beijing-based launch startup iSpace in November and December 2023. The Zhuque-3 VTVL-1 is powered by an engine model that will be used for orbital flight, as with iSpace’s tests.

The recent hops also highlight the competition within the Chinese commercial launch sector to develop a reusable launch vehicle.

The Chinese government first opened up sections of the space sector to private capital in late 2014. These developments are seen to be a reaction to commercial developments in the U.S. The first launch vehicles developed were small, light-lift solid rockets. The first Chinese commercially-developed liquid propellant rockets launched last year.

Landspace meanwhile has plans to get back into orbit this year, following two successful Zhuque-2 methalox rocket launches last year. The company aims to launch three Zhuque-2 rockets in 2024, Landspace vice president Huang He told CGTN in December. It plans to double this cadence year on year, launching six times in 2025 and 12 in 2026.

Regarding Zhuque-3’s roadmap, Landspace CEO Zhang Changwu told Chinese media last month that the firm is working on a 200-ton full-flow staged-combustion-cycle engine, to be ready in 2028. 

This engine would power a two-stage reusable launch vehicle with a diameter of 10 meters. The launcher appears to challenge the planned Long March 9 reusable rocket being developed by the China Aerospace Science and Technology Corp. (CASC), the country’s state-owned main space contractor.

A series of Chinese state-owned and commercial launch entities are currently developing reusable rockets.
