Surprised we didn't already have a thread. DART launched successfully at 0621 UTC today (23 Nov 21). Mission page here, encounter (as in collision) with small satellite of 65803 Didymos in late Sep/early Oct 2022.

In practical terms, this becomes a problem in terms of lead times & complexity even if compositional variables aren't considered. It would be difficult to built, test, and launch a powered redirect mission with a short lead time, but a DART-like impactor would be comparatively easy. In fact, building & storing (with ongoing maintenance & testing) a powered system for short-notice launch would be considerably more expensive than doing the same for an impactor mission.
Hard to say what, if anything, will eventually be decided here re an operational asteroid deflection system. But DART definitely provided a baseline set of interesting questions to ponder. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
