Hong Kong’s first astronaut, Lai Ka-ying, is scheduled to deliver a live lecture from space to students and educators at her former school, Tsuen Wan Public Ho Chuen Yiu Memorial College, on Tuesday morning. The event, set to begin at 9:50 a.m., will also be broadcast to schools across Hong Kong and Macau.

Lai will be joined by her Shenzhou-23 crewmates, mission commander Colonel Zhu Yangzhu and Zhang Zhiyuan, in the interactive session known as the “Tiangong Class.” The 90-minute program is organized jointly by the Hong Kong and Macau governments alongside the China Manned Space Agency.

The event will feature an expert-led lecture, in-orbit demonstrations, and a question-and-answer segment aimed at providing participants with a deeper understanding of the space environment. Authorities have encouraged primary and secondary schools to view the live broadcast on campus, with additional streaming available through the Information Services Department’s website, Facebook page, and local television stations. A delegation from Macau is also traveling to Hong Kong to attend the lecture in person, alongside representatives from the youth sector and innovation and technology communities.

Officials described the session as a unique educational opportunity designed to enhance aerospace science knowledge and inspire students’ interest in the field. The program is also intended to nurture aspirations, encourage boldness in exploration, and foster a sense of patriotism and national identity among young learners.

The Shenzhou-23 mission, launched in May, includes Lai, a 43-year-old police superintendent and mother of three, who serves as the mission’s payload specialist. While aboard the Tiangong space station, the crew is conducting over 100 scientific experiments ranging from biomedical research—such as studies involving mice and artificial embryos—to materials testing and investigations involving new energy-storage technologies.
