CosmoCube: Listening for Ancient Whispers on the Far Side of the Moon

To unravel the mysteries of the Cosmic Dawn – the period after the Big Bang but before the first stars – scientists are planning to send a tiny spacecraft, CosmoCube, to the far side of the Moon. Earth's noise pollution makes detecting faint radio signals from this era incredibly difficult. The Moon will act as a giant shield, allowing CosmoCube to listen for signals from early universe hydrogen, potentially revealing clues about the universe's origin, galaxy formation, and the Hubble tension. This UK-led mission, a collaboration between the Universities of Portsmouth and Cambridge and the Rutherford Appleton Laboratory, aims for lunar orbit within five years.
