Contracts to save Kerbin from doomsday Asteroids

[Blaarkies]

A new asteroid spawns, with the perfect orbital parameters to flyby Kerbin, maybe even touch the atmosphere or hit Kerbin itself! The end of Kerbalkind approaches, while the player on the other hand is trying to build a ridiculous tree swing on one of the Mun arches...

I am looking for a mod which will add a contract for every asteroid that is on a near pass trajectory with Kerbin. These contracts get completed once the Asteroids trajectory is no longer a threat. It should be simple:
    - Default: If you don't want to do it, then just don't take these contracts. If you do take them, you get the usual penalty for canceling them etc.
    - Hard: These contracts are forced upon you, there is no backing out. Long term time-warping will be a real problem this way, but to each his own.

Maybe you HAVE to leave a kerbal behind on each asteroid, their name changing to Bruce Willis for a moment

Yes! And if you fail, all of your buildings should be destroyed.  I've been waiting for this mod.
