Am  still uncomfortable with with the  astronomical no pun expense of robots on outer planets when we have far more pressing needs back back here in objective reality. There's a much much cheaper yet outstanding job can think of  before we risk  those investments on the  proponents of this cosmology including with it the Globe. They wouldn't even have to travel very far to do it: That is for them to build a construct  to take a direct measure of Earth curvature and demonstrate practically their claim  and they have the burden of proof.
