Born: 4 July 1997
Birthplace: Pasadena, California
Best known as: The first rolling robot to land on Mars
The Sojourner rover (officially named Sojourner Truth after the American abolitionist) is an exploratory robot which landed on Mars on July 4, 1997. Sojourner was part of NASA's Mars Pathfinder mission, dedicated to exploring the surface of Mars. As planned, Sojourner rolled around the planet's surface taking scientific readings of various bits of rock and soil. The plucky robot lasted until at least September, when its communications with Earth were finally cut off due to failing power.
