Sojourner
Sojourner was a NASA rover that explored Mars in the late 20th century with the task of analyzing the composition of the Martian rocks and atmosphere.

The rover landed in 1997, and the location was named the Carl Sagan Memorial Station; by 2155, a monument stood in the location and was classed as a Mars Heritage Site. ()

During its mission, Sojourner approached a rock known as "Yogi". (, opening credits)
