At 8:14 a.m. on May 11, 2026, the Long March-7 Y11 carrier rocket carrying the Tianzhou-10 cargo spacecraft blasted off from the Wenchang Spacecraft Launch Site in China. About 10 minutes later, the Tianzhou-10 cargo spacecraft successfully separated from the rocket and entered its designated orbit. The spacecraft’s solar panels then unfolded smoothly, marking a complete success of the launch mission.

It is reported that Tianzhou-10 carried a lightweight, high-resolution greenhouse-gas point-source collaborative detection payload, led and developed by the Hong Kong University of Science and Technology, capable of monitoring carbon emissions from space. Simply put, the payload can monitor carbon dioxide and methane emissions across the globe's mid-to-low latitudes at an altitude of around 400 kilometers above the Earth. This marks the first time such monitoring capability has been achieved by a spacecraft worldwide. It is also the first scientific research payload from Hong Kong to join national scientific missions aboard China’s Tiangong space station.
