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.
