2004 - Saturn Orbit insertion of Cassini-Huygens begins at 01:12 UTC and ends at 02:48 UTC.

1976 - Smithsonian National Air and Space Museum founded.

1917 - With great fanfare, the mirror for the Hooker 100-inch telescope arrives on Mount Wilson. Local businessman John D. Hooker donated the funds for the glass, which was manufactures from the same material used for wine bottles by Saint Gobain glassworks in France. Still the largest solid plate glass mirror ever cast, the 100-inch mirror weighs 9,000 pounds and is 13 inches thick. From its inauguration in November 1917, the Hooker Telescope remained the largest telescope in the world until 1948. Its great legacy is the foundation of our knowledge about the origin of our Universe.
