Darn, that's handy, I've been spelling it out all the time...<br /><br /><br />Anyway, back to Europa, Gravity will never be right, always too cold, radiation protection impossible now and if ever possible probably to expensive for an object as big as Europa. Unless you're prepared to dive real deep Europa always going to be short of useful heavy elements lik iron, titanium, copper, etc.. Soft landing on Europa also takes great deal of fuel. Round trip even more so. Don't get me wrong, would love to have inhabited world with view of Jupiter, but , boy oh boy, lotta' work to make Europa the one. <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>
