"Gravity 2" recyclable liquid launch vehicle plans to make first flight in 2025

The 2023 China (Wenchang) Commercial Aerospace Summit Forum was held in Wenchang. Oriental Space and Hainan Wenchang International Space City officially signed a launch vehicle launch and recovery Hainan base project, and conducted in-depth cooperation around the launch and recovery of the "Gravity 2" recyclable liquid launch vehicle. , serving the needs of large-scale constellation networking and high-orbit rocket launches.

Oriental Space will build a Hainan base for launch and recovery of launch vehicles. The project is located in the Wenchang International Space City Rocket Industrial Park and is expected to start construction in 2024.

The base will focus on building rocket launch technology preparation workshops and rocket recovery and testing workshops, which will be used for rocket body status inspection, system testing, overall testing, satellite and rocket docking before rocket launch, as well as sub-stage rocket cleaning and instrument equipment inspection after recovery. Replacement, trial testing and other work.

Gravity 2 has a take-off weight of 927 tons, a take-off thrust of 1,420 tons, a low-Earth orbit carrying capacity of 25.6 tons, a 500-kilometer sun-synchronous orbit carrying capacity of 19.1 tons, and a geosynchronous transfer orbit of 7.7 tons. It is planned to make its first flight in 2025.

Gravity-2 is positioned to meet the needs of large-scale networking of medium and large satellites and commercial high-orbit launches. It is a medium-to-large launch vehicle with the main characteristics of ultimate cost-effectiveness/high-orbit launch/core-stage recovery.

The rocket adopts a two-stage and a half configuration of liquid core stage + solid boost. The first stage of the core uses 9 units of Oriental Space's self-developed Force-85 liquid oxygen and kerosene engines, and the second stage of the core uses 1 unit of the Force-85 liquid oxygen and kerosene vacuum version. The engine and booster inherit the Gravity-1 boost technology.
