About

Scott Manley is someone who fell into YouTube because he felt a deep compelling need to teach people orbital mechanics and rocket science so they could play Kerbal Space Program, now, years later the gaming videos are less important and the pure science is the main thrust. My degrees are all in Physics and Astronomy, so much of the rocket science and engineering I've learned is self taught, always learning, always teaching. I used to do this as a hobby, along with my day job in software development, but that recently came to an end and I'm really appreciating everyone who has chosen to support my work through Patreon.

Video Description

Computers were essential to navigating the Apollo spacecraft to the moon, they were some of the first computers that needed to be small and compact, at least by the standards of the computers of the day. Apollo spacecraft carried 4 onboard computers at launch: Launch Vehicle Digital Computer on the Saturn V Apollo Guidance Computer on the Command Module Apollo Guidance Computer on the Lunar Module Abort Guidance System on the Lunar Module The best compilation of documentation on the computers that flew on Apollo is Ron Burkey's research compiled for the Virtual AGC project https://www.ibiblio.org/apollo/ Information and transcripts from the Apollo Missions with some explanations are available from the Apollo Flight Journal site: https://history.nasa.gov/afj For even more technical details on the AGC I recommend CuriousMarc's series on restoring one to working order https://www.youtube.com/watch?v=2KSahAoOLdU
