They
Know Something We Don't? Scientists Plan Mission To
Blow Up (Something?) ‘Hurtling Towards Earth’
It
seemed far-fetched on the silver screen. But the
European Space Agency is planning to launch a mission
similar to the plot of Hollywood movie Armageddon, in
which Bruce Willis and his intrepid team attempt to
blow up a huge asteroid that’s hurtling towards
Earth. The real version, if it goes ahead
in 2015, will see a satellite fired at break-neck
speed into a ‘test’ asteroid to see if its course
changes. The aim is to assess whether it
would be possible to save Earth using this method,
should we discover that an asteroid is on a collision
course with our planet. The mission,
called Don Quijote, will involve sending two
spacecraft towards a near-Earth asteroid. One will be
an ‘impactor’, which is fired into the asteroid,
the other an orbitor that will analyse data from the
experiment.
