...North American Air Defense Command, the watchdog of all objects in orbit, listed 4,552 pieces of hardware-ranging in size from a Soviet space station to such bits of space junk as an astronaut's glove, stray cameras, and even nuts and bolts. In the coming years NORAD's job will become still harder. By the mid-1980s, the number of orbital objects may double, making it more difficult to tell what is up, and whether it belongs to friend...
...M.I.T.'s Lincoln Laboratory, to gether with researchers elsewhere, has come to the rescue of the overtaxed satellite watchers. Using the latest in silicon-chip wizardry, it is setting up a worldwide network of monitoring stations that should vastly expand NORAD's ability to keep tabs on orbiting objects...
There was, nevertheless, plenty of suspense as Skylab slipped ever closer to its doom. The craft was monitored by the worldwide network of NASA and NORAD's space-tracking stations. From NORAD'S underground headquarters in Colorado Springs, Colo., calculations about the craft's flight were transmitted to the Skylab Control Center at the Lyndon B. Johnson Space Center near Houston. There Charles Harlan, the Skylab flight director, estimated the vehicle's probable reentry point, and the possible dangers. He, in turn, was responsible for advising the Skylab Coordination Center at NASA headquarters in Washington whether...
...entry into the atmosphere. At that point, a higher-level interagency team of experts, including NASA Administrator Robert A. Frosch, will take up positions in the Skylab Coordination Center on the sixth floor of NASA headquarters in Washington. Getting his information and recommendations from the Houston center, NORAD and the Marshall Space Flight "enter at Huntsville, Ala., Frosch will make the final decisions on what, if anything, should be done to try to influence Skylab's final fall...
...Skylab's disintegrating parts occur somewhere along a path of 40,000 miles?nearly twice the circumference of the globe. At two hours, the final anticipated flight track still extends over a 13,000mile path. Testing its prediction on a falling Soviet Cosmos booster stage on April 29, NORAD made an estimate two hours before re-entry? and missed the actual impact points in the Pacific by 4,000 miles...
