A totally irrellevent and useless experiment conducted at the public expense.
BAH!
I got MY money's worth.
Untrue, and uninformed.
This experiment is yet another confirmation in another technical realm that we can intercept high-speed objects (the comet is traveling several times faster than the fastest manmade ICBM). So for missile-defense, it has value.
Likewise, learning precisely how far we can tweak the orbits of large objects is valuable, as is learning more about the composition of comets, especially should we need to alter or destroy one some day (e.g. one on an Earth impact trajectory).
You have to start somewhere, after all.
Not only is this going to shed light on the makeup of comets and perhaps the early solar system, this experiment proved once and for all the ability of the United States protect the planet from spaceborne threats.
You misspelled irrelevant.
Your lack of imagination is only exceeded by your ignorance.
To a degree, I agree that this is not the best use of public money.
However, the liberals can no longer say that you cannot hit a bullet with a bullet. It has been done.
Irrelevant? Not to me. The comet has huge value as a resource. All we need is property rights.
