The Chinese University of Hong Kong is the second university in Hong Kong.

This launch finally (phew!) flew while I was sleeping at 06:37 UTC and was a success, with the Pakistan satellite being PRSC-EO2. It wasn't the only one on the SD-3 though, 6 others are on board including CUHK-1 from the Chinese University of Hong Kong, the city's 2nd university.Feb 12, 2026

A ship is heading to the South China Sea to launch a rocket.

Interesting to see this ship heading way down to the South China Sea to launch this rocket (2nd try BTW since late Dec.) when it can launch towards SSO closer to home. Perhaps to allow the Pakistan sat to phone above home & to get a 2nd home port working (Yangjiang, Guangdong)?Feb 12, 2026
