Today, I learned that:
Looking at today’s full moon, I cannot forget that it is exactly 47 years since man first set foot on non-terrestrial ground, on 1969-07-20. Of course everyone remembers Neil Armstrong’s “small step for a man, a giant leap for mankind”. Reference #1 has more about that historical feat.

But did you know that the source code of the program used in the computer of the Eagle, Apollo 11’s moonlander, is now available to the public?
If you are curious about what it looks like, see references # 2 and 3 below.
But of course there are interesting views on Mother Earth, as well. Today’s header photo was taken by my wife, Maria José, in Kokkari, island of Samos, Greece, on 2008-07-11. Enjoy!
… That’s what I learned in school !
