...much. Mission Director Kraft, noting that when McDivitt thought the booster was 400 ft. off, it was really 2,000 ft. away, said: "It's pretty hard to tell distances up there by eyeballing it." Next August's Gemini 5 flight, how ever, will have sophisticated radar for rendezvous exercises...
...same time, U.S. Navy and Air Force jets kept up their pounding of targets to the north. Barracks and PT boats, radar stations and ammo dumps caught the brunt of the aerial assault, and the bomb-line boomed ever closer to Hanoi. U.S. planes struck within 45 miles of the North Vietnamese capital, as if to challenge the half-dozen Soviet Ilyushin-28 jet bombers discovered by high-flying U.S reconnaissance planes late last month and at present sitting idly at Phucyen, just northwest of Hanoi. U.S. officials assume that the planes are Russian-piloted and represent Moscow...

Most of the Junk Patrol boats do not have radio, leave alone radar (only 12 of their ships have radar...

They will be able to study Mars for long periods at close range, sending back several kinds of maplike pictures, including intimate views of Mars made by infra-red light and by radar. A single orbiter will be able to chronicle an entire cycle of the Martian seasons, watching the growth of vegetation (if it really is vegetation) and mapping the fleeting details that were once interpreted as the famous Martian "canals," which are now thought to be optical illusions. It can measure...
