For those of you still recovering from watching THAT asteroid-induced tidal wave take out a father and daughter as they calmly contemplated their imminent deaths (see the movie “Deep Impact” for details), the idea of grabbing asteroids in space might make you sigh with relief.
In April this year, NASA announced a budget proposal for the “Asteroid Initiative”, which would use robotic technology to capture small asteroids that are hurtling towards Earth. After capture, the asteroid would be placed in a stable orbit around the Moon. Astronauts could then visit the rock to take samples or use it as a sunny stopover on future journeys to Mars.
The proposed launch date for the capture craft is 2017-ish.
But in the last few weeks, debate around the Initiative has hotted up. NASA announced a Grand Challenge to find out more about asteroid threats to our planet and now the space agency is being told to take a chill pill. Scientists are disgruntled because they weren’t consulted. They think the mission should be more clearly defined or it could end in disaster. On top of this, of course, there’s always the issue of cost.
If capturing an asteroid sounds like sci-fi to you, here’s a shortened version of how it would work…sorry about the music…I couldn’t resist.
