BALLS on the moon: China set to launch Africa's 1st lunar science mission in 2029

Key Points:

• China's Chang'e-8 mission, scheduled for 2029, will carry Africa's first lunar exploration payload, the BALLS (Bounced African Low Lunar Sphere) radio astronomy array, to the moon's south pole to study low-frequency cosmic signals.
• BALLS consists of three spherical probes equipped with low-frequency radio antennas designed to operate in the radio-quiet lunar environment, enabling observations below 20 MHz that are impossible from Earth due to atmospheric interference.
• The Africa2Moon project, led by the Foundation for Space Development Africa and SARAO, involves collaboration across multiple African institutions and aims to demonstrate lunar technology and radio astronomy capabilities with plans for a future array of 55 antennas.
• The BALLS probes were developed on a limited budget by volunteers and assembled in South Africa for testing by the Chinese team, highlighting the potential for Africa's growing role in space science and international partnerships.
• Future missions envision larger, self-deploying antennas for enhanced scientific return, contingent on continued collaboration with China, with the broader lunar science community expressing support and inspiration from the project's progress.
