Nasa to harpoon a comet!
To extract samples from wily comets, which have just a millionth of Earth's gravitational pull, a harpoon- or ballista-style device may be the best option.
To test the idea, NASA engineers have constructed a six-foot-wide harpoon to whack rock samples in a laboratory.

Daniel Smith - a long time ago, in a galaxy far away just north of Watford, Daniel fancied himself as a scientist but turned out to be the worst scientist since that bloke who mapped out all those canals on Mars that turned out to be scratches on his telescope's lens. Luckily, he is now not working on the Large Hadron Collider inadvertently creating a black hole that would swallow the world but is safely behind a desk writing this blog, bringing you the fantastical underbelly of nature... weird science.
