ATTENZIONE! Il Go per il lancio è stato dato per oggi, 8 dicembre, con finestra dalle 15.00 alle 18.22! Io non potrò vederlo
ma chi ne ha la possibilità lo faccia..
Il test prevede un lancio con immissione in orbita della capsula dragon, il completamento di tre orbite e una deorbit burn con rientro al largo delle coste messicane!
