About the Lecture

The lecture will discuss the engineering and construction of the James Webb Space Telescope, the technical and organizational challenges involved in creating and testing a uniquely complex deployable observatory, and the lessons learned from that work. The lecture will also consider how those lessons can be applied to future flagship missions that require order-of-magnitude advances in technology, performance and complexity.
