In 2019, as the world prepared to celebrate the 50th anniversary of the 1969 lunar landing, I listened to a BBC Podcast with my grandkids entitled:
13 Minutes to the Moon (
Figure 1) [1]. I highly recommend it for parents and grandparents as well as interested adults. I had a stake in NASA’s Apollo program because I worked for the company that made the back-up guidance system for the Lunar Module (LM). Initially called the BUGS (Back-Up Guidance System), it later became known as the Lunar Module Abort Guidance System (AGS). The AGS got its claim to fame in providing the guidance system for getting Apollo 13 back to earth [2]. I wanted my two youngest grandkids to get a taste of what it was like to be part of this momentous project, so this podcast was a great entry for them.
