...cities of Oslo and Tromsø are only 650 miles and 100 minutes apart. The psychological distance, however, is much greater, for Tromsø lies 200 miles north of the Arctic Circle, and its 40,000 inhabitants live two months of each year without seeing the sun. In this polar blackness or mørketiden* (murky time), the mentally unstable may slip over the edge into a temporary state of profound mental disturbance. Even those who are emotionally healthy the rest of the year may become unaccountably tense, restless, fearful and preoccupied with thoughts of death and suicide...
...search. His efforts were directed toward finding the emotional significance of the object. For his early work in the 1920's he shot trees, gnarled driftwood, machines--close--ups of plants and rocks. His work with close-ups led Strand to explore the world of human portraits. At one polar, he experimented with the idea of photographing people when they were answers that they were in view of the camera. This he did by attaching a false loss to the side of his 3 1/4 in. reflex camera...
...past three months, a strange moth-shaped satellite has been orbiting the earth in a nearly perfect polar orbit some 560 miles high. Sweeping down from the Arctic to Antarctica and back again every 103 minutes, the 1,965-lb. spacecraft has been taking as many as 752 pictures of the earth every day; each shot covers a 115-by-115-mile square. Unlike U.S. and Soviet spy satellites, which are on the lookout for military sites, the mission of NASA's first Earth Resources Technology Satellite (ERTS-1) is purely scientific. A direct spin-off of the space...
Along with its eye for color, ERTS has another useful capability. Because of the timing of its polar orbit, the satellite passes over the same spot on earth at almost precisely the same hour every 18 days. Lighting conditions at each site are thus unchanged (except for the slow seasonal drift in the angle of the sun and possibly different cloud cover). As a result, there is little difference in shadows from one picture to the next, and ERTS can quickly spot any changes in terrestrial features since its last visit...
Debus compared the past and future of the space program to the difference between the excitement of discovering the South Pole and the somberness of staying there to study the polar ice. "We are in the age of economizing now. In the background is the shining star of adventure. But now we must bring the benefits of space...
