Neil Armstrong's death reminds us of the huge effort that made manned space exploration possible. As a tribute to the man, here is one of a series of four programmes I made for Channel Four commemorating the 40th anniversary of his epic journey. You might recognise that the narrator is the sixth Doctor - Colin Baker !
Doctor who did it's own little tribute to the man when his mission to the moon became a focal point for the resolution of last year's episode Day of the Moon .
As his famous first words upon stepping onto the surface were watched by the millions of viewers around the world, the Doctor was able to broadcast his own message to defeat the Silents.
