BBC 水星和月球 Mercury and the Moon 天文纪录片 1080P中英字幕
The tiny planet Mercury is in the morning sky and Sir Patrick Moore talks about the latest news from Messenger, the spacecraft which is over Mercury at the moment. Mercury is often compared to the moon, which was last visited by man in December 1972. Forty years on, Dr Chris Lintott looks at the legacy of that mission, Apollo 17, and what it has been able to tell us about the moon.
