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.
-------------------- 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.

Even if less efficient (and considering the result last September, it seems quite effective!), multiple KIs could work just as well for more massive objects, just sending one after the other in a sequence (Shoemaker-Levy-9) style. One can separate the impacts by enough time for debris to dissipate to ensure the next one hits the target without running into (of course, a KI can be completely inert by the time it makes contact; as long as it has mass that's all that's needed).
(And I'm sure the PDCO and many others have already considered everything we discuss here anyway) |
