Nasa sky survey probe blasts off
Asteroids and comets watch has began, but what will happen if a rouge asteroid or comet is actual sighted will USA nuke it, or will we see other methods used to deflect an impeding disaster where possibly every species over 25 kilos will be made extinct.
As Hollywood pushed the project forward, possibly that could be true.
A Nasa satellite designed to uncover hidden cosmic objects has blasted off from California.
The Wide-field Infrared Survey Explorer (Wise) blasted off from Vandenberg Air Force Base on a Delta II rocket just after 1409 GMT.
It will pick up the glow of hundreds of millions of astronomical bodies.
The probe is expected to uncover objects that have never seen before, including some of the coolest stars and the most luminous galaxies.
The $320m mission will do this by scanning the entire sky in infrared light with a sensitivity hundreds of times greater than ever before.
Viewing the sky with "infrared glasses" can lift a veil on many objects that are not visible to the naked eye.
