2: Hubble: The Beginning01/20/15
This segment looks at the state of astronomy before Hubble and the difficulties of observing from the ground that drove the need for a space telescope. Astronomers instrumental in the Hubble project in the 60s and 70s reflect on how the design of the telescope was forced to evolve because methods used by ground-based observatories weren't practical in space.
