The Mariner series of spacecraft were interplanetary probes designed to investigate Mars, Venus, and Mercury. The program included a number of firsts, including the first planetary flyby, the first planetary orbiter, and the first gravity assist. To date, Mariner 10 is also the only spacecraft ever to perform up-close observations of Mercury.
