Woo hoo! What amazing news, especially given the difficulties during the landing.

For those who didn't see the original coverage, you can see some brilliant photos of the bounce the lander made during it's landing on the comet here: http://www.space.com/27788-philae-comet-landing-bounce-photo...

Also a hat tip to the earlier missions (such as the Beagle probe that was lost on Mars) which emphasized the importance of retaining radio contact for as long as possible during landing and being able to send and receive commands with the minimum amount of hardware reconfiguration once landed.

What a fantastic start to Sunday!
