NASA's Plan to Turn the Moon Into a Telescope Looks Like the Death Star

"A newly funded concept envisions a kilometer-wide radio telescope built inside a
crater on the far side of the Moon. Whoa."


"Not only would this telescope avoid all the radio interference produced by
humans, it would also be observing the universe without the veil of an atmosphere.
Earth’s atmosphere is quite useful for keeping us all alive, but it also blocks
many wavelengths of light from reaching ground-based observatories, including low-
frequency wavelengths that exceed 10 meters.

“An ultra-long-wavelength radio telescope on the far side of the Moon has
tremendous advantages compared to Earth-based and Earth-orbiting telescopes,�
Bandyopadhyay said in his proposal abstract.

“LCRT could enable tremendous scientific discoveries in the field of cosmology by
observing the early universe in the 10–50m wavelength band (i.e., 6–30MHz
frequency band), which has not been explored by humans to date.�"

That's cool. I hope they build it not too far from the near side.
Because such a radio telescope can't be tilted, it observes a portion of
the sky near the local vertical. If the local vertical downward is a
line pointing to Earth, then you don't get a very long baseline for
interferometry with an Earth based telescope. Some very interesting
things could be observed if you do interferometry between a
kilometer-wide radio telescope on the moon and the Arecibo Observatory
or FAST if the moon radio telescope is not too far from the near side.
