Absolutely no benefit to sending a few people to Mars
E.P. Grondine — (archived)

In case you two haven't realized it yet, Mars is not "Earth-like".

Four major problems face even limited manned exploration:

1) Back-contamination
2) Radiation
3) prolonged low gravity
4) sexual isolation

and not only is Zubrin nowhere close to having good solultions for any of them, NASA isn't close either, and further has no realistic plan for tackling them...

But let's wish all this away, so we can all live in some 'efing fairyland.

The energy costs of ferrying "colonists"
to Mars are so high that no one will want to pay them, at least for many years to come.

So what the hell is the point of such an enormous expenditure right now, particularly when NASA management is doing such a miserable job dealing with the quite real and quite deadly impact hazard?
