Spacecraft

The planet was visited by only one spacecraft, Voyager 2 on August 25, 1989.

More than 300 robotic spacecraft have explored destinations beyond Earth orbit.

NASA's Voyager 1 is the only spacecraft so far to leave our solar system.

Four other spacecraft will eventually hit interstellar space.

Two spacecraft have visited Mercury: Mariner 10 flew by in 1974 and 1975;

The BepiColombo spacecraft is planned to arrive at Mercury in 2025.

Although not a production vehicle, the greatest speed ever reached by a manned aircraft that isn't a spacecraft was made by the North American Aviation X-15A-2.
