The US has set its sights on NASA's next manned space mission. But where? Mars? Too far, that will come later. The moon? Been there, done that. An asteroid? You're correct.
Plans are underway for a 2017 mission liftoff to send robots to an asteroid, wrap it in a bag, and then tow it into an Earth orbit near the moon. In 2021, astronauts will be launched to rendezvous with the asteroid and and test technology for mining, deflecting a potential threat, and planning future missions — such as a trip to Mars. Senator Bill Nelson (D Fla) released plans for the mission.
The Obama administration wants to give NASA $100 million in 2014 to start it up. It hopes the cost will peak at $1 billion, although a recent study by the Kleck Institute (PDF) estimates a similar project to cost $2.6 billion. The recent recent near miss by asteroid 2012 DA14 and the meteor that landed in Russia, injuring about 1,200, helped speed up development of this mission.
Why this project in the midst of budget cutbacks, the fiscal cliff, and today's financial conservatism?
First, to save the world. There are millions of asteroids that orbit around the sun, but about a thousand are big enough to cause major damage — such as the extinction of dinosaurs. The path of an asteroid can usually be detected years in advance, and a very minute percentage ever collide with Earth. But some asteroids, like 2012 DA14, which actually passed through the Earth's atmosphere, have not been detected until it's almost too late. NASA's asteroid project looks at ways to deal with a potential asteroid collision, such as deflecting the rock harmlessly past Earth.
Get rich quick. Perhaps the biggest reason to visit these space objects is the unlimited potential for valuable resources. Some asteroids are said to contain large amounts of water, which could be converted into rocket fuel for longer space missions, say, to Mars. Plus, it has been estimated that a single asteroid could contain more plutonium than has been mined in the history of Earth. Remember pet rocks? Imagine how much money could be made with asteroid rocks.
How are they planning to do it, what do asteroids look like, and who else is planning missions to asteroids? Read on.

Plans are to nab a 500-tonne, 7- to 10-meter-wide (25- to 33-foot-wide) asteroid.
