Cape Town is at the centre of the global space economy as host of the International Astronomical Union (IAU) General Assembly. This is the first time in over 100 years that the event is on African soil.
The event, which began on August 6 and will end on August 15, has attracted over 1 800 delegates (80% are first-time visitors to the city). This influx is expected to significantly benefit local industries, particularly tourism and hospitality.
Held every three years, the IAU General Assembly brings together leading astronomers from around the globe to advance the field of astronomy through international collaboration. The event was secured by the Cape Town and Western Cape Convention Bureau, powered by Wesgro, in 2018.
Business events like this are pivotal to the Western Cape’s economy – boosting visitor numbers and showcasing the region’s expertise across various sectors. These gatherings directly influence foreign investment, export opportunities and tourism growth with conference delegates estimated to spend around R6 400 (€322) per day, according to Wesgro CEO Wrenelle Stander.
Stander said hosting the IAU General Assembly highlights the region’s growing prominence in the space economy. “Cape Town and surrounding areas, including Stellenbosch, have emerged as a leading hub for space startups in Africa. Companies like Simera Sense and NewSpace Systems are thriving here, focusing on specific satellite components and technologies. They leverage international partnerships and utilise local expertise and supply chains.”
Storied history
The Western Cape has a storied history in satellite development, dating back to the 1980s, leading to the launch of South Africa’s first satellite, SUNSAT, in 1999. Today, the region boasts a vibrant space startup ecosystem and has been instrumental in advancing space science through collaborations with major local universities: Stellenbosch University, the University of the Western Cape and the University of Cape Town.
These institutions play a critical role in satellite development and nurturing the next generation of scientists and engineers. Looking ahead, Wesgro is preparing to launch a study to assess the local economic impact of the space sector, aiming to identify investment opportunities and areas for accelerated growth. “With strategic support, South Africa’s broader space economy holds significant potential for success, creating jobs and positioning the country as a key global player,” Stander added.
Hosting the IAU General Assembly will help elevate the space sector on the national agenda and inspire new initiatives for growth, she said.
James Vos, Cape Town's Mayoral Member for Economic Growth and Tourism, highlighted the city's commitment to creating new opportunities by bringing together key players in the global space ecosystem. He emphasised that Cape Town has a strong tradition of innovation and remains open for business.
Dr Ivan Meyer, Western Cape Minister of Agriculture, Economic Development and Tourism, welcomed the IAU General Assembly in highlighting the province’s competitive space technology economy: “Our space heritage reflects our dedication to scientific exploration and positions the province as a critical player in global space endeavours”.
He noted the impressive collaboration between the South African National Space Agency (SANSA) and NASA in the Deep Space Ground Station in Matjiesfontein, Western Cape. This partnership supports NASA’s Artemis programme, which aims to further explore the moon’s surface and send the first astronauts to Mars.
“Space research offers vast economic opportunities. This exciting project showcases the Western Cape’s dedication to innovation and strong partnerships,” Meyer said.
EDITOR’S NOTE: The IAU, a member of the International Council for Science established in 1919, is headquartered in Paris. Its mission is to promote and protect the discipline of astronomy in all its aspects through international cooperation. The organisation has over 12 000 individual members across 90 countries, including South Africa.
