...days before Pioneer IV's successful takeoff, the Air Force launched its first Discoverer satellite from Vandenberg Air Force Base in California. Discoverer was the U.S.'s first attempt to put a satellite into polar orbit, which would make possible surveillance of the whole of the earth's surface. The booster...
...reassuring to know that the United States can send a satellite, albeit a diminutive sphere in comparison to the Russian planet, around the sun. It is not so heartening to read about the snafu which resulted in "losing" the mute and more mundane "Discoverer I," the first polar satellite...

Next morning at 11:54 the Hans Hedtoft's radio crackled an S O S: "Collision with iceberg." Less than an hour later came word that the engine room was filling fast from a gash in the riveted steel hull...

...extra 200-ft. bulge of rock over an area equivalent to the Atlantic Ocean. This extra mass would attract enough sea water to raise sea level about 50 ft. above the theoretical curve of an ideally plastic earth. None of the newfound bulges are large compared to the polar spin-flattening (about 13 miles), but they may cast new light on the earth's mysterious interior...
