# MeerKAT Radio Telescope Array

South Africa's 64-dish MeerKAT radio telescope is currently the most sensitive radio telescope in the Southern Hemisphere, producing breakthrough astronomical discoveries since 2018.
- Technology Readiness Level: 9/9
- Impact: 3/5
- Investment: 3/5
MeerKAT is a 64-dish radio telescope array in the Karoo, South Africa, operational since 2018 and designed as a precursor to the SKA. Each dish is 13.5 meters in diameter, and the array achieves angular resolution and sensitivity that rival the world's best radio telescopes. MeerKAT has produced landmark discoveries including the clearest-ever image of the Milky Way's galactic center, the detection of giant radio galaxies, and observations of transient phenomena like pulsars and fast radio bursts.

The telescope was designed, built, and is operated by the South African Radio Astronomy Observatory (SARAO), with significant indigenous engineering content. South African engineers developed the dish structures, receiver systems, and the correlator (the digital system that combines signals from all 64 dishes). The data processing pipeline handles petabytes of astronomical data, pushing the boundaries of high-performance computing in Africa.

MeerKAT demonstrated that world-class 'big science' infrastructure can be built and operated in Africa. The telescope attracts international research collaborations, with observation time oversubscribed by factors of 3-4x. Its 64 dishes will be incorporated into the larger SKA-Mid array, giving South Africa a central role in the most ambitious astronomical project in history. The scientific infrastructure also serves as a catalyst for STEM education and advanced manufacturing capabilities across the country.
