The Chinese pseudo-company Ispace on December 10, 2023 successfully completed the second veritical hop flight of a rocket prototype, testing vertical take-off and landing for the eventual purpose of recovering its first stages, as done now routinely by SpaceX.

ISpace’s Hyperbola-2Y methane-liquid oxygen reusable verification stage lifted off from a pad at Jiuquan Satellite Launch Center in the Gobi Desert at 4:07 a.m. Eastern (1107 UTC) Dec. 10.

The Hyperbola-2Y reached an altitude of 343.12 meters, translating 50 meters to a landing zone and touching down with a velocity of 1.1 meters per second and an accuracy of 0.295 meters. The entire flight lasted 63.15 seconds, according to an iSpace press statement. The flight came just over a month after a first hop test Nov. 2. That test reached 178 meters and returned to its landing spot. iSpace says it will attempt a test at sea next year after completing ground tests.

Right now the race to become the second company or nation after SpaceX to return and reuse a first stage is between Ispace and Rocket Lab. No one else is even close, though there are a number of other Chinese pseudo-companies that are doing hop tests. Though Rocket Lab — which is not attempting a vertical engine landing but recovering the stage from the ocean — has already flown a recovered engine, as well as recovered several first stages for refurbishment, it has not yet flown a reused first stage. Based on its schedule, that might happen ’24.

Ispace meanwhile hasn’t yet flown to orbit the prototype’s rocket, Hyperbola-3. It hopes to attempt the first orbital test flight in 2025, with the recovery of its first stage in 2026.
