A First in Orbit

Dr Lai Ka-ying’s appointment as Hong Kong’s first astronaut marks a milestone for the city and for women in science. Selected as a payload specialist for China’s Shenzhou-23 mission, Dr Lai has taken up one of the most physically and mentally demanding roles in the world. Her achievement is significant in its own right as well as in what it represents -- expanding the boundaries of who is seen as belonging in space exploration, and serving as a visible Hong Kong STEM role model for all genders.

Her achievement also reflects the power of shared commitment. Dr. Lai’s husband, an engineer, set aside his own career for two years to care for their three children and support her training – an example of how family partnership can enable women to pursue ambitious goals.

Her success should not detract from the work needed to address gender-specific challenges women face in entering and advancing in aerospace. Research by the UN Office of Outer Space Affairs notes that women make up just 11% of astronauts globally and 30% of the public space workforce overall. For many, their experiences in this sector are concerning: 33% of women have experienced overt bias and discrimination since joining the space sector; 22% have experienced bullying; 16% had experienced sexual harassment; and about 10% had experienced physical harassment – all which shape women’s participation in the sector.

Other barriers begin long before recruitment. A study of 70 STEM networks across Asia revealed gender bias, stereotypes, and a lack of female role models affect how girls envision themselves pursuing and succeeding in STEM careers. This pattern is reflected in Hong Kong. Our own research on gender differences in STEM education points to similar factors contributing to Hong Kong’s underrepresentation of girls pursuing STEM. Addressing this requires early encouragement from parents and teachers, exposure to real-world STEM careers, and visible female role models. Stories like Dr. Lai’s remind us that progress towards gender equality is both institutional and also deeply personal—made possible when families and partners actively share responsibilities.

This is why we created our Girls Go Tech (GGT) Programme to inspire underserved secondary school girls to pursue STEM-related skills, subjects and careers – now extended to provide support at university and early career stages. We employ a broader ecosystem approach where we engage parents, teachers, schools and companies to ensure holistic support.

Space exploration has long captured the collective imagination. It reminds us that even the most seemingly impossible challenges can be overcome. At a time when our world faces urgent issues - from climate crisis to rapid technological changes - that spirit of possibility matters. Meeting these challenges will require the full breadth of all our talent. This is only possible if we commit to creating the conditions in which all girls can imagine, pursue and succeed in STEM – let’s make it happen!
