VIVAnews -In a Conference, William Shelton, the Chairman of the U.s. Air Force Space Command, concerned about the increasing number of man-made space debris.

"The number continues to increase. Now it is more than 50 countries involved in space exploration, "said Shelton, as quoted from space, may 10, 2011."Currently more than 20 thousand unused objects are in space, "he said.

Currently, Shelton, said it continued to monitor growth routinely of garbage dump space. "Look at the trend of growth, it is estimated that figure will rise three times in the year 2030," he said. "Whereas the possibility of the amount of waste that is 10 times more because the sensor we have currently not able to keep track of all the crap that is," said Shelton.

Horrible, call Shelton, objects to be garbage is very dangerous. "They can damage the space systems for military, civil space systems, commercial satellites, and others," he said. "No one is immune to the threat in a job at the moment," said Shelton.

According to Marshall Kaplan, expert space debris from the space Department, Johns Hopkins University, space junk in low Earth orbit have been accumulating since 50 years later. The addition of the last remains of the testing of anti-satellite (ASAT) belongs to China in 2007.

"One of these tests has increased the number of objects in the debris around 35 percent," said Kaplan. "It gets worse, the location was at an altitude of 865 km, the area most populated where an orbit satellites in General," he said.

Another case, clashed in February 2009, Iridium 33 communication satellite belonging to the United States with the cosmos, space shuttle Russia unused, at an altitude similar to China's ASAT test. Consequently, fractional debris more diffuse.

"The result of the launch of the satellite during the past fifty years, as well as two such events, is now the area between an altitude of 700 kilometers up to 1,300 kilometers there is jutaaan and medium-sized debris ranging from a few millimeters to a few meters, "said Kaplan.

Unfortunately, said Kaplan, the growth of the number of bins is not reversible. Space cleanup efforts would be too expensive. "Currently, there is nothing we can do. We do not have sufficient resources, technology does not exist, and there is no cooperation. Nobody wanted to fund that effort, "said Kaplan.

Kaplan added, clean the space is the ' industry continue to grow ', but nobody wants to work on. "Furthermore, politics, it is also not profitable," he said. (eh)
