“In my mind the universe has to be cyclic, so that in one galaxy if there is a planet maybe that has arrived at the point of becoming unlivable, you will find in another part of a different galaxy a planet that has just formed which is perfect for habitation. I see some kind of intelligent being, like us, skipping around the universe from planet to planet as, let’s say, the South Pacific Indians do on the islands, where they skip from island to island. When the first island blows up due to a volcano, they will have their progeny on all these other islands and they will be able to continue the species. I think that’s what the [alien] space program is all about. –Al Worden
Worden served as command module pilot for the Apollo 15 mission, which set several moon records for NASA, including the longest lunar surface stay time, the longest lunar extravehicular activity and the first use of a lunar roving vehicle. Worden spent 38 minutes in a spacewalk outside the command module and logged a total of 295 hours, 11 minutes in space during the mission.
