Its orbit was suggested by the brilliant intuition of Professor Bepi Colombo of the Institute of Applied Mechanics in Padua. Mercury 10 thus made a first Venus flyby, followed by a first Mercury flyby, followed by a second and a third Mercury flyby, thus multiplying the observation opportunities. The mission was very limited in budget: only $98 million. It would ultimately cost $97 million. The subsequent Mariner 11 and 12 missions were renamed, thus terminating the Mariner program. Mariner 11 and 12 are now better known as Voyager 1 and 2.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mariner 10 is launched, flying past Venus on its Mercury flyby, transmitting 4,165 images.
