https://www.youtube.com/watch?v=jiKMFj7HGkc Paul Hill, Ralph Wilkins and Dr. Jenifer “Dr. Dust” Millard host.  Damien Phillips, John Wildridge and Dustin Ruoff produce. From  Dec 31, 2021. A look back at the greatest distance any human has ever been from Earth! In this episode we take a look at how the 1960s saw NASA and the Russians sending people farther than anyone had ever been before.    From spacewalks to moon landings, how far have humans ever travelled? And what about space probes? Some of those are now leaving the solar system and showing us what interstellar space is like.   But please do help us out by subscribing to the show: https://www.youtube.com/awesomeastronomy   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
