help Mars Pathfinder FAQ
What was the name of the rover deployed by the Mars Pathfinder mission?
Mars Pathfinder successfully deployed a small robotic rover named Sojourner onto the Martian surface in 1997. It was the first successful rover to explore the planet, weighing just over 10 kilograms and analyzing the chemical makeup of nearby rocks.
Where on Mars did the Mars Pathfinder lander touch down?
The spacecraft touched down in an ancient flood plain called Ares Vallis. Scientists chose this location because the rushing floodwaters from billions of years ago would have deposited a wide, diverse variety of rocks for the rover to analyze.
What innovative landing technology did Mars Pathfinder demonstrate in 1997?
Instead of using traditional retro-rockets for a soft landing, Mars Pathfinder utilized a groundbreaking airbag system. The lander bounced across the Martian surface inside a protective cocoon of massive airbags before safely coming to a stop.
What was the official name of the Mars Pathfinder lander after it touched down?
In honor of the late astronomer and science communicator, the lander was renamed the Carl Sagan Memorial Station. The mission was managed by NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California.
