The satellite whirled around the globe, a tiny silver buble lost in the sky's infinitude. With the perfect precision built into it by the Jet Propulsion Laboratory at Pasedena it photographed onevery pass the changing features of the busy earth below. Nothing escaped it, as nothing escaped its many brothers form many lands, which also followed, each in its particular equatorial or polar orbit, the activiites of the nations that launched them and the acitivites of those nations enemies. All were on guard.
