At 19:40 Beijing Time on October 14, 2026, the Zhuque-2E Y4 launch vehicle lifted off from LandSpace's liquid oxygen-methane launch pad at the Dongfeng Commercial Aerospace Innovation Test Zone. In a rideshare mission carrying 10 satellites, the rocket delivered ADA Space's Xingshidai-39 and Xingshidai-44 through Xingshidai-50 satellites, along with LandTower Intelligent's Guangchuan-03 and Guangchuan-04 satellites, into their designated orbits. Aboard the satellites, 16 TY-Space star trackers also reached orbit, marking the complete success of the mission.
The eight satellites — Xingshidai-39 and Xingshidai-44 through Xingshidai-50 — were independently developed by ADA Space. They will primarily conduct on-orbit verification of high-performance computing payloads, high-speed inter-satellite and satellite-to-ground laser communications, and large radiative cooling wings.
Guangchuan-03 and Guangchuan-04 are next-generation laser data transmission test satellites developed by LandTower Intelligent to validate key technologies for satellite networking. They will carry out dedicated in-orbit verification of core technologies, including highly integrated onboard processing units, large-aperture high-speed laser communications, integrated laser routing and communication modules, and new solar array power systems. These tests will further refine the technology framework for large-scale constellation networking.
The TY-Space PST3S-L3 and PST3S-H5 star trackers used in this mission have also been deployed on multiple satellite and constellation projects, including Aurora Constellation-02, Xingshidai-24, and Tianyan-27.
