What little scientific output that has come from the ISS has come from automated equipment that does not need the help of astronauts, like the </span>Alpha Magnetic Spectrometer<span class="gmail_default" style="font-family:arial,helvetica,sans-serif"> and the Cold Atom Laboratory. Such instruments are on the ISS not because they need people to operate them but because they need lots of electrical power and the ISS with all its solar panels has lots of that, they only thing they need from the astronauts is for them to stay out of the way and not to touch anything.</span></font></div><div> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><i><span class="gmail_default" style="font-family:arial,helvetica,sans-serif">> </span>I am talking of the smallest and<span class="gmail_default" style="font-family:arial,helvetica,sans-serif"> </span>least ambitious moonbase that we can build and operate with the money<br>

If you were willing to spend between 10 and 100 times as much as a Moon base cost you could have a Mars base, and that would buy you one additional week's worth of human spirit ignition. And then they'd get tired of watching that rerun too.</font></div><div class="gmail_quote"><font size="4"><br></font></div><div class="gmail_quote"><font size="4"><span class="gmail_default" style="font-family:arial,helvetica,sans-serif">John K Clark</span></font></div></div>
