Tiny satellite will use the dark side of the Moon as a shield
TL;DR
The UK-developed satellite CosmoCube will orbit the Moon's far side to detect the 21-centimetre line, a signal from the early universe, potentially revealing insights into the cosmic dark ages.
✦ Why It Matters
Consider supporting space research initiatives that aim to uncover the universe's early history.
Key Takeaways
- Explore the potential of small satellites in cosmology.
- Investigate the role of dark matter in star formation.
- Utilize lunar environments for deep space observations.
- Stay updated on advancements in satellite technology.
How It Works
CosmoCube will orbit the Moon's far side, where it will be shielded from Earth's radio noise for about 40 minutes during each two-hour orbit. This allows it to detect the 21-centimetre signal from hydrogen atoms, which is crucial for studying the early universe.
The satellite will deploy a sensitive radio antenna and use advanced calibration techniques to ensure accurate measurements.
