Manned explorations the way?

That they may be inevitable does not support the argument that they
are necessary. By the way, how can you know that the junk (and
biological contamination) we left on the Moon will not cause some
problems at some time in the future? At the very least, the
contamination will not be spread by wind. Such is not the case on a
planet with an atmosphere, like Mars. Again, you have the foresight
of a grave robber.


So - we should stay home, because otherwise we will probably co-immigrate
with some bacteria? Earth has been exchanging organic matter with many other
celestial bodies for billions of years, via impacts.
