LCROSS Centaur impacts the permanently shadowed floor of Cabeus crater
A spent Centaur upper stage struck Cabeus at roughly 2.5 km/s. The trailing shepherding spacecraft flew through the ejecta plume for about four minutes, returning spectra, before impacting itself.
Historical — it happened, and the record is settled.
