Hong Kong astronaut to operate world-first greenhouse gas observatory on Tiangong
World’s first light, high-res space observatory to pinpoint CO2 and methane sources from orbit.
Hong Kong’s first astronaut, payload specialist Lai Ka-ying, will deploy a groundbreaking locally developed observatory during her six-month mission aboard China’s Tiangong space station. The Multi-Spectral Imaging Carbon Observatory, which arrived at the station earlier this month, is being hailed as the world’s first lightweight, high-resolution, high-precision space-based instrument capable of measuring carbon dioxide and methane emissions from Earth. Professor Li Jia of Lingnan University, leading the research team, stated that the imaging equipment can pinpoint the location and intensity of greenhouse gas sources, providing critical data to reduce carbon footprints in the Greater Bay Area and across mainland China.
Lai, a computer data specialist, is part of the three-member Shenzhou-23 crew set to launch from Jiuquan Satellite Launch Centre on Sunday. She has been trained extensively to operate the payload, and Li expressed full confidence in her abilities. The observatory’s data will help identify major emission hotspots, enabling targeted climate action. This mission marks a significant step for Hong Kong’s space research capabilities and contributes to global greenhouse gas monitoring efforts.
- Lai Ka-ying will operate the Multi-Spectral Imaging Carbon Observatory on Tiangong for at least six months.
- The observatory is the world’s first lightweight, high-resolution, high-precision space imager for CO2 and methane.
- Data will be used to reduce greenhouse gas emissions in the Greater Bay Area and mainland China.
Why It Matters
First-of-its-kind space-based imaging provides precise emission data to guide climate policy in China and beyond.
