Imagine placing a super-sensitive radio telescope on the far side of the Moon- that hidden side we never get to see from Earth- all to capture faint whispers from the Universe's every first moments. That’s exactly what NASA is gearing up to do with its exciting new mission, LuSEE-Night.
Why the Moon's far side? Because it’s a quiet zone, shielded from all the radio noise that floods Earth, like from cell phones, satellites, and radio stations. This silence makes it the perfect spot to try and state signals from the "Dark Ages"- a mysterious era billions of years ago before stars and galaxies even existed.
LuSEE-Night is set to travel to the Moon's far side abroad a commercial lander later this year. Once there, it will unfold a set of specially designed antennas to catch incredibly faint radio signals. These signals come from neutral hydrogen gas that filled the universe during its earliest days- capturing them could give us an amazing glimpse into how the cosmos grew from a vast, dark emptiness into the brilliant galaxy-filled sky we see today.
Since the far side never faces Earth, LuSEE-Night will communicate through orbiters circling the Moon, sending back precious data for scientists here to study.
Even though this mission is relatively small, it’s a giant leap for space science. If all goes well, it could lead to bigger radio telescopes on the Moon, turning it into a cosmic listening post that helps us understands the universe's earliest moments.
