But oddly, as Feynman pointed out, they only used Venus, and not Mars 
(or Jupiter, although the synodic period is pretty long for Jupiter)..

Mars is pretty prominent in the morning sky these days, as it always is 
when a spacecraft is about a third of the way there, which is why I was 
reminded of it.
