This is a cool year for space exploration - not one but two rovers on Mars, Cassini and Huygens at Saturn and Titan, Spaceship One reaching space, Hubble doing the usual amazing stuff...

What's unbelievable is that Nasa are talking about letting Hubble fall out of orbit ?! This is probably the most important scientific instrument ever created by man, and we won't have a replacement ready for years. They've got to do everything they can to keep it operational.
