BBB (Bouncing Bertie Boffin) here.
Can you even imagine how awesome it must be to land on a comet?
You would be bouncing with excitement. Well I would, for sure.
You know, when I bounce, I'll be honest with you, I only stay up in the air for a fraction of a second.
Now look at this picture of the European Space Agency's Philae lander last week hitting the surface of Comet 67P/Churyumov-Gerasimenko for the first time. And then bouncing off again.
It was nearly two hours before Philae came down again the second time.
The next bounce lasted a 'mere' seven minutes.
Frankly I'd have been happy with that.
Earth's gravity field is such a drag.
