My country successfully launched the Communication Technology Experimental Satellite No. 15

China News Service, Beijing, March 10 (Ma Shuaisha, Cui Wanying)

At 1:17 am on March 10, 2025 Beijing time, my country successfully launched the Communication Technology Experimental Satellite No. 15 using the Long March 3B carrier rocket at the Xichang Satellite Launch Center. The satellite successfully entered the predetermined orbit and the launch mission was a complete success. The satellite is mainly used to carry out multi-band, high-speed satellite communication technology verification.

This mission is the 562nd flight of the Long March series of launch vehicles.

TJSW-15A is located at 90.3 E.
The second GEO object (TJSW-15C in my records as it is object 2025-045C at USSPACECOM) of an uncertain nature drifted west fast until Mar 25 when it was probably lost. Strange enough if we think of a large oject.
