Pathfinder lander

A group of scientists, all wearing white protective clothing, gather around a spacecraft as it's being folded into its launch position; a triangular pyramid shape. In Spacecraft Assembly and Encapsulation Facility-2 (SAEF-2), Jet Propulsion Laboratory workers are closing up the metal "petals" of the Mars Pathfinder lander. The Sojourner small rover is visible on one of the three petals.
