Could we? I assumed the whole point was to use a crater as a ready-made, almost-parabolic dish, meaning that only the receiver and suspension wires would have to be sent over -- vastly reducing the required payload vs constructing an entire 1km diameter dish in space.
- valuearb 6y agoA crater isn't a dish, you need to line with with antennae. The extra material to support those antenna in free fall is minor. But the cost difference in landing anything on the moon is massive. Every kilogram of payload sent to low earth orbit takes roughly 15 Kg of fuel. To land a Kg of payload on the moon requires roughly 80 kg of fuel.

You may get something similar by putting a satellite in earth syncro orbit on the dark side of the moon. https://www.nasa.gov/directorates/spacetech/niac/2020_Phase_I_Phase_II/lunar_crater_radio_telescope/ https://www.nasa.gov/directorates/spacetech/niac/2020_Phase_...
