Mechanical Design of the Mars Pathfinder Mission

The Mars Pathfinder Mission was a great engineering achievement for the National Aeronautics and Space Administration (NASA) and the Jet Propulsion Laboratory (JPL) which built the Pathfinder Spacecraft and the Sojourner TM Rover. The mechanical design of the mission hardware was critical to the success of the complex entry sequence and landed operations. A wide variety of mechanisms were employed with varying technologies and heritage. These mechanisms have played a key role in the mission which has greatly exceeded expectations.
