Sojourner and Astronaut on Mars.jpg: The classic image of humans and robots working together is depicted in this NASA artwork. Sojourner, the Mars Pathfinder rover named after former slave and famous abolitionist Sojourner Truth, is visited many years after its mission by a descendant of its namesake, in this artist’s rendering. Like the human, Sojourner the rover paved the way for those that followed. This image was produced for NASA by Pat Rawling.
