but i find it mind blowing that there's clever boffin's that can manage to land a small probe on a comet travelling at who knows how many thousand of mph that's 300 million miles away :worship:
I find it mind blowing that they can find money for pointless stuff like this rather than finding a cure for cancer.
You are aware, aren't you, that there is a constant significant risk of an Earth impact by a comet or asteroid? If we are lucky they land in remote places, like the ones in Siberia last year and in 1908. If one of those had hit a city it would have had the effect of a nuclear bomb. Try this one : [ame]http://en.wikipedia.org/wiki/Tunguska_event[/ame] - an eyewitness 40 miles away was burnt and thrown back some yards.I find it mind blowing that they can find money for pointless stuff like this
