Collision of Russian and U.S. satellite debris falling this week, part of the Earth (Figure).

The universe is not only a huge number of 2251 satellite debris, and the vast distribution range, from 198 km away from the ground to a height of 1689 km. In contrast, 33 Iridium satellites are located in the debris from the ground from 582 to 1262 km .between the height. "</ P> <P> researchers did not know exactly what satellite debris scattered in so many different reasons. .According to space weather news report, according to the researchers speculate that the universe after the collision the satellite 2251 may become fragmented, dispersed in all directions. .NASA said that because of debris increased, "Discovery" space shuttle was an increased risk of debris hit 6%. ."Discovery" set in the United States launched the evening local time March 11, will fly to 220 miles above the ground (about 354 kilometers) high, with the International Space Station for docking. .</ P> </ p>.
