    We should take care not to make the intellect our god it has, of course, powerful muscles, but no personality.
    Albert Einstein


    Who Was Born Today?

    1961: Yuri Ivanovich Onufriyenko, Russian major/cosmonaut, Mir, Soyuz TM-23

    Who Died Today?

    1923: Edward E Barnard, U.S. astronomer (5th moon Jupiter), age 65

    1973: Ira S Bowen, U.S. physicist/astronomer (Mt Wilson/Palomar), age 74

    Today in History:

    1971: Apollo 14 - USA Lunar Manned Lander (January 31 to February 8, 1971) Crew: Alan B. Shepard, Jr., Edgar D. Mitchell, Stuart A. Roosa. Shepard and Mitchell landed on the moon on February 5, 1971, in the Fra Mauro highlands, located at 3°40' S and longitude 17°28' E. They collected 42.9 kilograms of lunar samples and used a hand-held cart to transport rocks and equipment.

    1994: Clementine - USA Lunar Orbiter - (launched January 25, 1994) spent 70 days (between February 6 and May 5, 1994) in lunar orbit. The official name for Clementine is Deep Space Probe Science Experiment (DSPSE). It was a Department of Defense program used to test new space technology. Clementine was a new design using lightweight structure and propellant systems. Its four cameras mapped the surface of the Moon at 125-250 meters/pixel resolution. Clementine also used a laser to gather altimeter data which will make it possible to generate the first lunar topographic map.
