Stellenbosch University students are building advanced telescope electronics that will fly to the moon on China’s Chang’e-8 mission in 2029.
A groundbreaking piece of South African technology is destined for the lunar surface, marking a historic leap for the continent’s space exploration ambitions. In an extraordinary achievement of local engineering, students and researchers from Stellenbosch University have developed the electronic heart of a revolutionary radio telescope that will be deployed on the moon by the end of the decade. The ambitious project promises to unlock unprecedented scientific discoveries by capturing cosmic signals that are completely invisible from Earth.
The core of this exciting aerospace development can be mapped out by exploring the technology being sent into space, the hardware being designed and deployed, the launch that will take place, and why the lunar surface is the perfect location for this specific scientific endeavor. Being built is a technology demonstrator consisting of three high-tech composite spheres equipped with low-frequency radio antennas and complex electronics, humorously named Bounced African Low Lunar Spheres, or B.A.L.L.S. The sophisticated internal systems were developed by South Africa’s space engineering sector, which continues to thrive, at the Electronics Systems Laboratory at Stellenbosch University, with the final destination being the heavily unexplored south pole of the moon. The historic deployment will occur when the payload flies aboard China’s highly anticipated Chang’e-8 robotic lunar probe, which is officially scheduled to launch in 2029. The compelling reason scientists are going through the immense effort to place these spheres on the moon is that the Earth’s ionosphere naturally blocks and distorts radio waves below 20 megahertz; by placing the telescope on the moon, which has no ionosphere and minimal radio interference, astronomers will finally be able to observe an entirely hidden slice of the early universe.
This milestone is part of the Africa2Moon initiative, recognized as the very first all-African space exploration endeavor. Selected by the China National Space Administration as one of just eleven international payloads for the Chang’e-8 mission, the project represents a massive collaborative effort led by the Foundation for Space Development Africa. Stellenbosch engineers worked in close partnership with the South African Radio Astronomy Observatory, the South African National Space Agency, and multiple local universities to design hardware capable of surviving the brutal conditions of space. For Stellenbosch University, this prestigious payload is the latest chapter in a proud 35-year history of space engineering. The university’s Electronics Systems Laboratory previously birthed Sunsat, South Africa’s first satellite launched in 1999, and later contributed to the SumbandilaSat project. Now, by joining the Chang’e-8 mission, the university’s technology will actively contribute to the groundwork for the China-led International Lunar Research Station, a planned robotic base designed to eventually host human astronauts.

Four master’s students at Stellenbosch University successfully presented the working electronic systems earlier this year, completing a functional model that effectively transmitted data between the spheres and a mock lunar lander unit. Engineering a payload for the moon requires overcoming intense technical hurdles, as the electronic components must withstand extreme temperature fluctuations, harsh cosmic radiation, and the violent vibrations of a rocket launch. The technology demonstrator is currently in its final rigorous testing phases and is scheduled to be shipped to China by mid-2026 for strict payload integration assessments by the Chinese space agency. Once the final flight models are approved and rebuilt using specialized space-grade materials, they will establish a permanent observatory in the lunar dust. This initial three-sphere deployment will serve as a crucial proof of concept for what project leaders hope will eventually become a massive array of 55 spheres, one representing every single nation on the African continent. As South Africa prepares to cement its technological footprint on the lunar south pole, this student-driven innovation loudly proves that local aerospace talent is fully equipped to pioneer deep space exploration on the ultimate global stage.
