Wanted: man to land on killer asteroid and gently nudge it from path to Earth

It is the stuff of nightmares and, until now, Hollywood thrillers. A huge asteroid is on a catastrophic collision course with Earth and mankind is poised to go the way of the dinosaurs.

To save the day, Nasa now plans to go where only Bruce Willis has gone before. The US space agency is drawing up plans to land an astronaut on an asteroid hurtling through space at more than 30,000 mph. It wants to know whether humans could master techniques needed to deflect such a doomsday object when it is eventually identified. The proposals are at an early stage, and a spacecraft needed just to send an astronaut that far into space exists only on the drawing board, but they are deadly serious. A smallish asteroid called Apophis has already been identified as a possible threat to Earth in 2036.

Chris McKay of the Nasa Johnson Space Centre in Houston told the website Space.com: "There's a lot of public resonance with the notion that Nasa ought to be doing something about killer asteroids ... to be able to send serious equipment to an asteroid.

"The public wants us to have mastered the problem of dealing with asteroids. So being able to have astronauts go out there and sort of poke one with a stick would be scientifically valuable as well as demonstrate human capabilities."

A 1bn tonne asteroid just 1km across striking the Earth at a 45 degree angle could generate the equivalent of a 50,000 megatonne thermonuclear explosion. Attempting to break it up with an atomic warhead might only generate thousands of smaller objects on a similar course, which could have time to reform. Scientists agree the best approach, given enough warning, would be to gently nudge the object into a safer orbit.

"A human mission to a near Earth asteroid would be scientifically worthwhile," Dr McKay said. "There could be testing of various approaches. We don't know enough about asteroids right now to know the best strategy for mitigation."

Matt Genge, a space researcher at Imperial College, London, has calculated that something with the mass, acceleration and thrust of a small car could push an asteroid weighing a billion tonnes out of the path of Earth in just 75 days...

Where do I get the application form?
