CosmoCube is a suitcase-sized satellite designed to detect faint radio signals from the early universe, specifically from the period before the first stars formed known as the cosmic dark ages. The spacecraft will operate from the far side of the Moon, using it as a natural barrier to block radio interference from Earth. This mission aims to study how the first stars ignited and how dark matter contributed to early galaxy formation.


Understanding the cosmic dark ages and the formation of the first stars and galaxies represents a fundamental gap in our knowledge of cosmic evolution. This mission could provide direct observational evidence of dark matter's role in structuring the early universe and help explain the transition from the primordial universe to one filled with stars.


CosmoCube will use the far side of the Moon as a shield from Earth’s radio noise to search for a faint signal from the universe before the first stars existed. The suitcase-sized satellite could reveal how the cosmic dark ages ended and how dark matter helped build the first galaxies.
