Example for Italian - EnglishPiano della NASA per inviare una sonda sulla superficie lunare L'ente spaziale americano, NASA, ha annunciato che la prossima missione sulla Luna non sar limitata a orbitare intorno al satellite, ma che includer anche il lancio di due veicoli spaziali che raggiungeranno la superficie lunare per mezzo di un atterraggio con schianto. Il Lunar Reconnaissance Orbiter (LRO), la cui missione principale quella di esplorare la Luna, invier una navetta di appoggio e una sonda a impatto verso un cratere situato al polo sud lunare. Sembra che il cratere sia ricco di idrogeno e forse ghiaccio. Questa missione va vista nel contesto di una serie di iniziative che hanno lo scopo di riportare gli astronauti sulla Luna e, forse, di farceli rimanere per un periodo superiore rispetto a quello della missione Apollo. NASA's Plan to Send a Probe on the Lunar Surface The American space agency, NASA, announced that the next mission to the Moon will not be limited to orbit around the satellite, but also include the launch of two spacecraft that will reach the lunar surface by means of a crash landing. The Lunar Reconnaissance Orbiter (LRO), whose mission is to explore the Moon, will send a shuttle to and support a probe into an impact crater located on the south lunar pole. It seems that the crater is full of hydrogen and possibly ice. This mission should be seen as part of a series of initiatives that aim to bring the astronauts on the moon and, perhaps, let us stay for a period longer than the Apollo mission.
