...record this radiation in two ways. First, it can concentrate on a small spot in the center of the solar disc and record, in about 27 minutes, the intensity of radiation over the whole ultraviolet spectrum. During its other "mode" of operation, the eye of the spectrometer will scan the whole disk of the sun, back and forth, bottom to top, recording at just one wavelength. Each complete scan will take about four and one-half minutes and will provide a crude ultraviolet picture of the whole sun. Both these kinds of information will be recorded on magnetic tape...
What caused the death of Thresher? To find an answer, Admiral Anderson ordered the bathyscaph Trieste from the West Coast to scan the depths and convened a 5-man board of inquiry. Perhaps the most likely theory is that a fitting gave way under immense pressure, water blasted through with such force that air compression within the submarine produced white-hot temperatures that melted metal in the instant before Thresher plunged to the muck-covered bottom-where her secret may remain forever...
...impossible for ultraviolet radiation to penetrate the atmosphere and therefore the satellite, to be launched this fall, may give astronomers a "picture" of solar radiation which they have never had before. When finally in the satellite, the observatory's instrument will scan the sun and the information it sends back to earth will help explain how the sun works, how it affects the earth, and how its intense radiation might endanger a future astronant...
Instead of taking quick pictures of large parts of the sky, radio telescopes must scan slowly, gathering details one by one. As a radio telescope's beam (its field of sensitivity) moves across the sky, the radio waves collected by the dish are focused on an antenna and detected as an extremely feeble electrical current. This current is amplified by intricate electronic apparatus until it is strong enough to move a finely balanced pen and draw a wiggly line on a strip of paper. Small wiggles mean little or nothing, but a good-sized bulge means that some object...
...instrument will circle the earth aboard an observatory satellite, OSO II, which will collect data on the sun in two ways. First, it will again concentrate on a small dot in the center of the sun. It will also scan the entire disc of the sun in alternating east-to-west and north-to-south directions. Each complete scan will take about four and one-half minutes...
