Observation of far-infrared radiation is impossible to make from the ground because of obstructive water vapor. The balloon will rise above this vapor at an altitude of 18 miles, Noyes said...
...Vapor Trails. In the North Vietnamese capital, 60 miles inland, loudspeakers urgently awakened the sleeping city: "Comrades, attention! The enemy is near Hanoi." At 9:30 a.m., the second wave of the U.S. air assault appeared.

But one weapon in the fight, a pro-SST primer published in 1969, is still being used in some of the nation's elementary schools...
Discovery of the valley has increased speculation that water-dependent forms of life may once have existed-or still exist-on Mars. That possibility has also been strengthened by readings from Mariner's instruments. They indicate that about 100,000 gallons of water vapor escape daily into space from the Martian atmosphere. Scientists believe that the vapor and carbon dioxide are being continually vented from volcanoes in the same kind of process that created the earth's early atmosphere...
