La cometa Siding Spring ha "sfiorato" Marte questa domenica a una distanza di circa 136'000 chilometri e con una velocità di 202'000 chilometri orari.
L’Agenzia spaziale europea, che ne ha dato notizia, ha precisato che un tale evento avviene una volta ogni milione di anni.
Alle 20:27 (ora svizzera) la cometa si trovava a 135'895 chilometri dal pianeta rosso, ossia l’equivalente di un terzo della distanza che separa la Terra dalla Luna.
Le telecamere dei satelliti che orbitano intorno a Marte, come pure quelle dei due robot presenti sulla sua superficie - Opportunity e Curiosity – sono state dirette verso Siding Spring in modo da poter raccogliere il maggior numero di informazioni al suo riguardo. Le immagini, stando alla NASA, dovrebbero giungere sulla Terra nei prossimi giorni.
Curiosity ha filmato la cometa e invierà le immagini sulla Terra in questi giorni
