...This Is the Best." The graceful rocket strained on its launcher as its engines built thrust. It lifted in grandeur in the morning sun, trailing a white-hot fire that looked like an inverted candle flame. Seconds after lifting-first slowly, then ever faster-Vanguard's farewell roar reverberated over the Cape in a blanket of sound. Half a mile from the pad, Canaveral men cheered: "Go, baby, go! Keep going, baby! Don't quit, baby...

...Navy's test satellite, Vanguard I, may be small, but it is high and wondrously sophisticated, and it will probably stay in space many years longer than any of its earlier rivals. Its elliptical orbit varies between 404 miles and 2,466 miles above the earth. When it is ending its climb toward the high point (apogee), the satellite is moving slowest: only 12,000 m.p.h. Then it swoops down to the low point (perigee) and increases its speed to 18,400 m.p.h. It makes a full trip around the ellipse, 34,100 miles, in 134 minutes...

Stable Orbit. Since Vanguard I never dips low enough to tangle with serious air resistance, it should stay in space for a very long time, certainly years. Instead of spiraling down slowly, like the Sputniks and Explorer I, it will stay on an almost stable orbit that will be only slightly disturbed by irregularities of the earth's gravitation...

...Vanguard I might seem too small (diameter: 6.4 in.; weight: 3.25 Ibs.) to carry much cargo, but an amazing amount of delicate apparatus was packed into it. Most novel items: its six solar batteries made of subtly treated silicon that look out through windows distributed over the sphere in such a way that at least one of them is always facing the sun. Each battery develops about 25 milliwatts of power when in sunlight, and feeds a miniature transmitter that broadcasts continuously on 108.03 megacycles. Another transmitter, powered by a mercury battery, broadcasts on 108 megacycles...

...reflect back into space. But it looks black to the long infra-red (heat) waves. Since black surfaces radiate well, it permits the satellite to get rid of its internal heat by radiation. The system seems to be working well. Both transmitters have reported that the temperature inside Vanguard I is staying at a reasonable level, certainly below the point where the germanium transistors in the electrical circuits will be damaged...
