Hubble at 25: Hubble – The Beginning

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.

Amazing, a space telescope that started out well below 100 MHz CPU speed in 1990. My cellphone runs at 4, 200 MHz (4.2 GHz). What it's been upgraded to by now? Thanks Hubble team for almost 29 years of noteworthy space photography!
