The Hongmeng Programme, designed to detect the universe’s “infant cries,” consists of 10 satellites forming a low-frequency radio telescope array. The satellites will travel to the far side of the Moon, a naturally quiet “radio sanctuary” shielded from Earth and solar interference, allowing the system to capture extremely faint signals from deep space. The project aims to shed light on the turbulent epoch hundreds of millions of years after the Big Bang, before the first stars formed.
