...force of geography, Russian test explosions are in northern latitudes. Evidence was presented that fallout from Soviet polar shots is caught in the downward drafts of arctic air and delivered to earth quite rapidly (in about a year), while debris from equatorial explosions probably stays up longer. Largely as a result of Russian polar shots last year, twice as much strontium 90 fell on the U.S. as in any previous year...
...egotist. As an apprentice in the British merchant navy, he was termed "the most pigheaded, obstinate boy I have ever come across" by his first skipper. Born a middle-class Irishman, he burned to force his way to the top of Britain's upper crust-and chose the polar route for the expedition...

...after Explorer Robert Peary first got there, the U.S. nuclear submarine Skate cleaved up to the surface through densely packed winter ice. There Skate's officers and men, on their second underwater voyage to the Pole (TIME, Aug. 25), conducted a solemn ceremony: they scattered the ashes of Polar Explorer Sir Hubert Wilkins, dead since last December, who had envisioned the possibility of journeying to the Pole by submarine. That done, Skate submerged, went on to complete a record trip of 3,090 miles and twelve days under the ice pack, in which it surfaced ten times through...
...Then a Hawaiian station heard a brief, faint signal. After five more hours of silence, Air Force stations in Alaska and the U.S. began to pick up sporadic signals. Last week, nearly five days after launch, the Department of Defense felt able to announce that Discoverer I was in polar orbit. But it had not been spotted visually, perhaps because its orbit carried it over the world's inhabited areas in bright daylight or darkness, when it is hard to see. The nine-station radio fence that spans the U.S. and is supposed to detect any silent satellite...
