Landsat's electronic eyes scan patches of the earth's surface 115 miles square, one after another. (It takes 30,000 images to show the entire planet.) The satellite views each square in different colors, some seven different wave lengths in all, including several "invisible" infra-red frequencies. The images are sent as a stream of radio signals to earth stations, where they are assembled by a computer into full pictures. In many instances, scientists arbitrarily choose the final colors to represent a specific condition; for example, blazing red might indicate healthy crops, while black would mean ailing...
...super-duper cargo plane, with NASA has some sort of high-powered United Parcel Service. Further dashing the quixotic nature of the space program has been the shuttle's secret military uses. The fourth shuttle flight last June contained classified military cargo and little else. Rumored to be an infra-red tracking and ranging device, the military stow-aways chillingly affirmed the political role which the shuttle will apparently play...
...pure research. When the plans for the shuttle were first unveiled, a half-dozen teams of scientists at the joint Harvard-Smithsonian astrophysics center in Cambridge received the thumbs-up to numerous projects designed for the shuttle. That number has dropped since then, with only one endeavor--an infra-red telescope--having a reservation for a trip in the near future and still receiving full NASA backing. Scientists at the Harvard-Smithsonian center are now anxiously awaiting the green-light on projects for now tabled...
...good this Neil Leifer is. The only camera in America better than Neil Leifer's is at Citibank." Leifer photographed Eder by mounting his Nikon with a 16-mm fisheye lens on the ceiling right over the middle of the cell, then using a remote-controlled infra-red signal to snap the shutter in order to keep himself out of the picture...
...lack business. The Defense Department has booked a quarter of the flights scheduled through the 1980s. The first of the Pentagon payloads was carried aboard Columbia on its most recent mission. Though officials refused to talk about the contents, the packages included a cosmic-ray detector, ultraviolet and infra-red sensors for gauging the tracks of enemy missiles, and a space sextant that will enable satellites, or even the shuttle, to navigate without guidance from earth. During the last flight, the only references to the top-secret devices came in the form of cryptic commands to the astronauts from...
