Why go that far and then not land people? You're already paid all the
costs and run the bulk of the risks. Either you think your lander
will work (in which case it might as well have people in it) or you
don't (in which case you might as well not bother).

A manned landing had never been done on the Moon until the first time
we did one, either. Hell, a manned landing had never been done on
EARTH up to a certain point in history.

Note that we felt no need to run an unmanned 'test' of either of those
prior to actually doing them.

Hogwash.

By you, perhaps. Others of us don't find the case for impossibility
nearly as convincing as you do.

I'm pretty sure Einar doesn't intend to let reality intrude upon his

There aren't that many interesting airless bodies of similar size
where those lessons would apply.
