India’s PRATUSH Computer Could Detect Signals From the Universe’s First Stars: Report
RRI’s PRATUSH—a credit-card-sized computer payload—will detect faint radio signals from hydrogen to study the “Cosmic Dawn”. Designed for deployment on the Moon’s far side, the system offers noise-free, efficient data handling using an SBC and FPGA combo. If successful, it could help determine when the first stars formed and expand our cosmic understanding.
