Un satellite della NASA, in orbita da quasi due anni attorno a Marte, ha dovuto compiere una manovra inusuale per evitare una collisione con una delle due lune del pianeta.
Gli esperti della NASA si sono infatti resi conto che la sonda MAVEN, il cui compito è di studiare quel che resta dell'atmosfera marziana, sarebbe andata a disintegrarsi su Fobos, il più grande dei due satelliti di Marte, entro meno di una settimana.
MAVEN, in termini astronomici, passerà comunque a un soffio dalla luna: il 6 marzo passeranno dallo stesso punto dello spazio a soli 2 minuti e mezzo di distanza.
