NASA Is Going To Crash a Satellite Into an Asteroid - Ecks - 07-05-2017
The National Aeronautics and Space Administration (NASA) is moving ahead with plans to try out deflection techniques on a passing asteroid to prepare for future, threatening space matter.
The space agency has entered the preliminary design phase for its Double Asteroid Redirection Test (DART). This represents the first trial of what's called the "kinetic impactor technique" of asteroid deflection. Put another way, NASA hopes that by hurling a refrigerator-sized spacecraft at one of the space rocks at a speed roughly nine times that of a bullet, it can knock the asteroid off course and save the Earth. The plan is to launch the first DART satellite at a binary asteroid called Didymos ("Twins"); the twin asteroids are scheduled to pass by earth in 2022 and 2024. (Neither pass poses any threat, according to NASA.) By striking one of the two asteroids, scientists will be able to measure the impact of the collision.

Seems like a giant waste of their limited funding imo. Given it's NASA, figuring out the geometry, mass, and velocity of the asteroids shouldn't be terribly difficult, then it's all kinematics. Even simulating that would be overdoing it.

While I can certainly see what makes you say that, I think it also comes down to the fact that despite best efforts, sometimes calculations are simply incorrect. This is a seriously expensive test, but one that may save our lives, or more likely, the lives of our children's children.

How exciting! I hope everything goes well.
