In the movie Armageddon, for instant, a team of oil drillers were sent up to land on the surface of the asteroid to blow it off. Hey wait! There could be valuable minerals up on that rock!
There are a lot more space debris drifting just outside of our atmosphere than any of us could ever think of. At any moment there could be thousands of satellites and tiny space rocks hovering above your head. But it doesn't take a rocket scientist to recognize the threat poses by asteroids. Dinosaurs were killed by an asteroid the size of Isle of Wight, which generated a force a billion times greater than the atomic bomb dropped on Hiroshima.
But what if we could catch one and bring it home? And maybe put it in Earth's orbit and perhaps do some real-time asteroid research, or, if the rock contains valuable minerals, we could send miners-cum-astronauts up there to generate some cash.In fact, according to the Chinese scientists, there’s a snazzy little number approaching the Earth right now. It’s about 30 feet (10 meters) wide. We can use conventional explosive, kinetic impactor and nuclear explosive as outlined in the paper.
The nuclear route, however, may not be advisable: “Because the nuclear explosion can release a very large amount of energy, the result may be a fragmentation of the target near-earth-object (NEO).”
But of course, should NASA decides to mine the next asteroid that's heading for Earth, please consider signing me up =).
