Hello,
I stumbled upon this really cool but barely watched YouTube channel where the Johnson Space Center NASA alumni chapter uploads really great monthly videos.
Normally one alumnus volunteers to give a presentation on a topic of their choice and it leads to fascinating discussions and presents not well known fun facts about many of the largest NASA programs from the people who ran them.
For example:
This is a great one where they reminisce about STS-1 on its 40th anniversary:
This one they discuss the direction that NASA is heading and how they feel about the current programs:
This one is a fun one where someone presents about all the animals that went to space and some hilarious and unbelievable stories about NASA’s early animal astronaut programs and some amazing pranks that NASA employees had pulled:
I recommend checking it out!!
