...same field. The discovery--a startling correlation between the movements of five earth satellites and radio wave emission of the sun--is the most marked relation between solar and terrestrial phenomena ever found. The man behind this important find is a good-natured, gray-haired man named Luigi G. Jacchia. A meteor expert by trade, Jacchia may be found more often than not hunched over a drawing board plotting graphs in a small corner office at the Smithsonian Astrophysical Observatory building on Garden St. Fittingly, it was his drafting work which led to his discovery of the correspondence...
...basking in the sun of my native Italy when the first satellite went up," Jacchia recalled. "I came back ten days after Sputnik I was launched. Everything was in a state of confusion. People were sleeping in my former offices. There was such general despair on people's faces that I decided to help." With his proficiency in upper atmosphere dynamics from his work on meteors, his help was not insignificant...
...know that if a satellite encounters atmosphere its angular momentum is decreased, and this produces a decrease altitude and a decrease in period. At first it was thought that the variations were due to the differing area presented by the satellite as it turned over and over in orbit. Jacchia wrote in the Smithsonian's "Special Report No. 9," issued February...
...latter eventuality, added almost as an afterthought, turned out to be the critical factor. During the summer it was determined in that spherical satellites also behaved in the same peculiar fashion as the cylindrical satellites. By late September Jacchia had discovered some periodicity in the acceleration of Sputnik II and ruled out change in presentation area of the satellite as a factor. He wrote...
...Luigi G. Jacchia, research associate at the observatory, described the relative freedom with which unskilled workers in the Soviet Union can move to different jobs and different cities. He added, however, that housing and job shortages do make such movement difficult, and that some government supervision is exercised...
