Mede het gevolg van het (moedwillig) ontbreken van lange-termijn visie. Alles wordt geleid door de waan van de dag & korte-termijn belangen. Wat weer samenhangt met om de 4 jaar verkiezingen & een maatschappij waar burgers geen lange-termijn zekerheden meer hebben, door invoering marktwerking e.d.

At 7:28pm GMT tonight in 1957 at the Tyuratam Test Range in Kazakhstan, the Soviet Union launched the first artificial satellite—Prosteyshiy Sputnik 1 (Elementary Satellite 1)—into low-Earth orbit, shocking the United States, igniting a Cold War space & ICBM race, and spurring the creation of NASA.

A color photograph of a contemporary duplicate of Sputnik 1 on display in a museum. It is basically a metal sphere with four long metal antennas protruding from it (all pointing in one direction), like feelers on an ant or whiskers on a cat.

he front page of the October 5, 1957, edition of the New York Times, with the triple-deck banner headline, "SOVIET FIRES EARTH SATELLITE INTO SPACE; IT IS CIRCLING THE GLOBE AT 18,000 M.P.H; SPHERE TRACKED IN 4 CROSSINGS OVER U.S." There is also a small illustration showing the satellite's orbital path.
