Folks have asked for a slightly shorter version of the Gene Cernan interview just focused on the $2 bill, without going into the technicalities of the astronaut's PPK lists. Here is that shortened video that tells the story of Gene's three time flown $2 bill, and why he carried it. Enjoy!
In 2010, astronaut Gene Cernan -- the last man to walk on the moon -- discusses in detail the $2 bill that he took with on all three of his spaceflights in honor of the memory of his father, who always carried it for good luck. This bill flew on Gemini 9, to lunar orbit on Apollo 10, and on to the surface of the moon during Apollo 17.
