Lai Ka-ying, Hong Kong’s first astronaut and payload specialist, will operate a locally developed observatory to monitor greenhouse-gas emissions from orbit [1].
This mission represents a significant step in regional climate monitoring, as it utilizes home-grown technology to identify specific pollution sources. By mapping emissions from space, researchers aim to create a more accurate data set to drive carbon reduction strategies across the region [1].
The observatory, created by Hong Kong research teams, uses specialized imaging equipment to track the location and intensity of greenhouse gases [1, 2]. Lai will operate the equipment while stationed aboard China’s Tiangong space station in low Earth orbit [1].
The project specifically targets emissions within the Greater Bay Area and other regions of mainland China [1, 2]. This orbital perspective allows for a level of surveillance that ground-based sensors cannot always provide, bridging the gap between local reports and atmospheric reality.
Professor Li Jia of Lingnan University highlighted the utility of the imaging equipment in a recent statement. "The imaging equipment could pinpoint the location and intensity of emissions, providing data that could be used to reduce carbon sources in the Greater Bay Area and elsewhere in mainland China," Li said [1].
The data collected will be used to pinpoint exactly where emissions are most concentrated. This precision is intended to help policymakers and environmental agencies implement more effective measures to lower the carbon footprint of the industrial hubs in the region [1].

The integration of Hong Kong-developed hardware into the Tiangong space station signals a shift toward more localized scientific contributions within the Chinese space program. By focusing on the Greater Bay Area, the mission transforms the space station into a practical tool for regional environmental governance, moving beyond general exploration toward targeted climate mitigation.
