Quite in advance with respect to the stated goals of its 2010 collider program, the Large Hadron Collider has produced yesterday night the instantaneous luminosity of 10^32 cm^-2 s^-1 in the core of the ATLAS and CMS detectors. This is great news for all of us: at such a collision rate, on average one top quark pair is produced every minute, and one 120 GeV Higgs boson (if the thing exists) every 10 minutes makes its apparition there! (Calculations are in this recent post).
Human presence in space enable us to do more than just observe Earth from a far. We develop space technology that come in handy here on Earth in numerous applications. Or, as is so touchingly demonstrated in the Chilean miners rescue 'miracle', we learn more about the human species (medical and psychological) so that we can literally help save human lives under extreme conditions here on Earth.
