Getting to Mercury Is Harder Than Getting to the Outer Planets. Earth Is Already Moving 67,000 Miles an Hour Sideways and a Spacecraft Has to Shed Most of That to Fall Inward. Mariner 10 Solved It by Flying 3,600 Miles Over Venus and Letting the Planet Slow It Down.

A spacecraft weighing about 1,100 pounds, built for roughly $100 million in 1970s money, made three passes at Mercury in 1974 and 1975 and...
