This could be very interesting. One of the doomsday scenarios has a major comet crashing into planet earth which could have the impact of several hydrogen bombs apparently. So what should the world do? Well, we're about to try and crash a satellite into a small comet this weekend. It WILL be televised! ( Of Course).
To make it complete we need commentary from "Mork of Ork." Robin Williams, call home!

Watch Deep Impact's Comet Collision Via Webcast
From SPACE.com:

You don't have to be a scientist to grab a front row seat when the NASA's Deep Impact spacecraft bears down on a comet between July 3 and 4.

Live webcasts of the event will be provided by NASA and several observatories, large and small, to offer skywatchers a digital view to the cometary collision.

NASA's Deep Impact mission is slated to crash an 820-pound (371-kilogram) Impactor probe into Comet Tempel 1 and record the event via a Flyby mothership, orbital observatories like the Hubble and Spitzer space telescope, and a myriad of ground-based telescopes from around the world. The impact is expected to take place at 1:52 a.m. EDT (0552 GMT) on July 4.
