What was the launch date of the Pathfinder mission?

Though completely successful and completing real objectives, the Mars Pathfinder mission can be regarded as a "proof-of-concept" for various technologies, such as airbag-mediated touchdown and automated obstacle avoidance, both later exploited by the Mars Exploration Rovers. The Mars Pathfinder was also remarkable for its extremely low price relative to other unmanned space missions. This was an important achievement, considering that approximately two-thirds of the spacecraft destined for Mars have either failed to launch or were lost en route.
