July 21 – Small Step; Big day

July 21st 1969 is going to take some beating as far as big days go.  I’ve been thinking about it, and it’s just really obvious that nobody has ever done anything even remotely as impressive as walking on the Moon.  The more one thinks about it, the less likely it seems that it was even possible with 1960′s technology (don’t forget that the processors used in the guidance system were smaller than the ones available in home computers just a decade later, and my android phone is obviously from a different planet).

Maybe something to top it will come along eventually (the first gay pope to visit  Mars, maybe?) but in the meantime, here are a couple of other events being commemorated in the enormous shadow thrown by Neil Armstrong’s boots.


1914  –  Discovery of Jupiter’s moon Sinope by S B Nicholsonwhile he was working as a summer assistant at Lick Observatory.  The ninth satellite of Jupiter to be spotted, Sinope was, as I say, discovered in 1914, but didn’t receive a proper name until 1975; until then it was simply “Jupiter IX”.  It was named, along with eight other moons, “on the recommendation of the Working Group for Planetary System Nomenclature” of the IAC.  Nicholson’s discovery was slightly serendipitous, as he was actually photographing “Jupiter VIII” at the time with the 36-inch British-built Crossley Reflector, a device the observatory had bought from it’s previous owner when it became obvious that the skies above Halifax, England, were a waste of a large telescope.


1998  –  RIP Alan Shepard.  Shepard (another of the Mercury Seven) was, as commander of Apollo 14, the fifth man on the Moon, and the first to play golf there.  It’s perhaps just as well that the Americans conquered the Moon.  I doubt the effect would have been quite the same when the first Briton on the surface got his dartboard out.


1961  – Launch of MR-1, the first unmanned spacecraft of the Mercury project.  A spectacular failure, it managed to attain an altitude of four inches in a flight lasting 2 seconds.


2006  –  Discovery of Actaea, the satellite of trans-Neptunian object  120347 Salacia.

    He estado mirando tus contenidos dos veces queriendo localizar algo diferente y sincesarmente es que
    de esta forma me ocurre. Cada que leo tus artículos siempre encuentro algo nuevo.
    Te prometo que llevo por lo menos 3 hrs. mirando cada
    una de las ideas que has desarrollado y me parecen realmente buenas.
    Deseo que no creas que intento ser tu stalker jeje. Ya en serio, quiero comunicarte que es una grata vivencia haberme encontrado con gente que posee grandes habilidades con las
    letras. Tengo la esperanza que sigas de este modo
    y que si se da el instante, tengamos la oportunidad de conocernos.
