The decision not to return to the Moon was a good one. Although men walked on the moon and returned safely it was a tremendously expensive project.

The decision 34 years ago to put money into unmanned craft was very wise because we would only be going between the Earth and Moon because everywhere else is just too far. Deeb is partly right when he says there is nothing do go back for.

The exploration dollar gets far more for unmanned exploration than for sending humans into space.

If anything there should be far more unmanned exploration with craft carrying multiple landers.
