No ESA is not coming to Ted Kennedy's aid vs Cape Wind windpower but they are planing Don Quijote a mission to impact an asteroid and measure the deflection thereby geting some data to assess the viability of impact oriented asteroid deflection schemes. Yes, it's time we struck back at the 'vermin of the skies'.

The primary objective of the Don Quijote mission is to impact the target Near-Earth Asteroid (NEA) and to be able to determine the deflection resulting from the impact. To achieve this, it will measure with extreme accuracy the asteroid's position in space before and after impact.
There is also a secondary objective, involving the so-called Autonomous Surface Package Deployment Engineering eXperiment (ASP-DeX). In this experiment a small device, an Autonomous Surface Package or ASP, would be released from the Orbiter spacecraft while it's on orbit about the asteroid. It would then passively free-fall towards the asteroid surface after its release, and touchdown within a certain distance of a target landmark, most likely the crater resulting from the impact of the Hidalgo spacecraft.

In addition, part of the mission secondary goals are to and study the asteroid's surface chemical composition and the characterization of the thermal and mechanical properties of the asteroid surface.
