World's first lunar radio telescope readies for far side mission


Radio astronomers like a bit of peace and quiet, so they're sending an historic first radio telescope to the Moon. To block out Earthside radio signals, the Lunar Surface Electromagnetics Experiment (LuSEE-Night) will set up shop on the far side of the Moon.

Astronomers try to get around this with electronic and digital filters, and siting telescopes in remote areas like Goonhilly in England or legally protected radio silent zones in the United States, South Africa, Australia and Brazil, but it's still not good enough – especially when it comes to listening to phenomena that's the equivalent of a cosmic pin drop. Instead of trying to beat all this radio noise, scientists and engineers at the US Department of Energy's Brookhaven National Laboratory, along with NASA, the University of California, Berkeley and Lawrence Berkley Lab have decided to up sticks and move somewhere a lot quieter. Part of the commercial Firefly Aerospace's Blue Ghost 2 lunar lander scheduled to fly late this year or early next, LuSEE-Night is a self-contained instrument pack designed to monitor low-frequency radio signals in the frequency range of 0.1 to 50 MHz and help astronomers to build up a complete picture of that band of the spectrum.
