Il laboratorio mobile Philae si è sganciato dalla sonda Rosetta e ha iniziato a scendere verso il nucleo della cometa 67P/67P/Churumov-Gerasimenko. Lo ha reso noto l'Agenzia Spaziale Europea (ESA).

L'impresa, destinata ad entrare nella storia del voli spaziali, richiederà circa sette ore per essere completata, intorno alle 17,00 ora svizzera.
Gli scienziati, nel corso della notte, sono rimasti con il fiato sospeso dopo aver rilevato un problema nel sistema di discesa che impedisce al piccolo robot di rimbalzare sul suolo della cometa al momento dell'atterraggio. In particolare sembrava non funzionare il piccolo motore a razzo che si trova sul "tetto" del lander e che deve entrare in azione circa 40 minuti prima che Philae si posi, per rendere la manovra più morbida.
