Your second thought to include the moon sound very interesting. So, is
their an offer to the nasa or the government to get some help? Please
excuse, when I ask so easy here. I mean a big radio telescope in a moon
crater will found many other scientist interest and today this is
makeable.

Easier would be to have a BIG "SKA" type array in space at the Earth-Moon Lagrange point beyond the moon. No need to make a gentle landing on the moon for all the parts! Also, any non-functional elements can be simply allowed to drift out of the way and another brought in as required.

Keeping that lot sychronised would be a good technical challenge (;-))

The various Lagrange points are going to get crowded...

Take a look at NASA's present list of new 'big' projects.

Have fun,
