U.S.S.R.'s Mars 3, approaching Mars, had detected possible evidence of earth's magnetic tail farther out in space than previously reported, Pravda article said. Both Mars 2 and Mars 3 had passed through area 19 million km (12 million mi) from earth, where they had detected magnetic field. When Mars 3 passed through area it recorded streams of charged particles whose velocities differed from those observed in solar wind. Soviet scientists speculated that particles of solar wind were mixed with those of earth's magnetic tail. (NYT, 12/5/71, 9)
