Once again, the blood turns to ice.
Once the mourning is over, let's hope this causes us to redouble our efforts in space exploration, and to provide adequate funds and proper execution for it. It's too important to let slide away.
(It wasn't very widely reported, but Pres. Bush's latest budget includes funding for a brand-new unmanned Jupiter mission in the late 00's - one that will not just sling a probe out there, but will put a craft out there capoable of navigating between the various moons in the Jovian system for a ten-year exploration mission. Hopefully, that a sign that this administration will not dismiss the space program.)
