One hundred and two hours and 12 minutes after leaving the Earth, the crew of Apollo 10 was on the far side of the Moon. The two spacecraft -- the command-service module and the lunar module -- were traveling separately, and as they plowed ahead with their flight plan and had a bit of a snack, all three men heard some "spacey music" coming in over their headsets.
For more on this story, including the transcript of when the crew heard the weird sounds, check out my latest blog post over on Vintage Space at Popular Science.
And there's loads of olde timey space to dig into on my blog, Vintage Space, too!
