Orienspace has a backlog of hundreds of satellites for Gravity-1 launches.

Orienspace is targeting a quarterly Gravity-1 launch cadence in the coming years.

Orienspace’s Gravity-1 performed its second flight in October 2024.

CAS Space’s Kinetica-2, LandSpace’s Zhuque-2E and Zhuque-3, Orienspace’s Gravity-1, and most Long March rockets can meet Qingzhou’s stated launch requirements.

Orien Space’s Gravity-1 Y3 rocket is planned to launch in mid-July 2026.

Shanghai facilities could potentially support the Ceres-1S, Gravity-1, Jielong-3, and Long March 12 launch vehicles.
