The moon has colors, not just shades. A modern camera can adjust and capture what the moon actually looks like, unlike the cameras they had in the 60’s and 70s.
I think most people would want to photograph the earth. You want colour for that.
Man it’d be really cool to shoot a black and white film on location at the moon.
8mm, silent!
Even ignoring the fact that the moon is not all grey, what if you wanted to take a selfie?
You can take selfies with a B&W camera too
If you’re spending a billion dollars to go to the moon, why are you trying to save $1 with a cheap camera?
If you want an expensive camera you can use one of these Leica M11 Monochrome
Except if you’re going there for the single good reason there is for going to to Moon, i.e, to show everyone how dead and lifeless it is and how beautiful and fragile the Earth is by comparison. As William Anders did very successfully with Ektachrome color film in 1968.
