VIVAnews -In a Conference, William Shelton, the Chairman of the U.s. Air Force Space Command expresses concern about the increasing number of man-made space debris.
"The number continues to increase. Now it's been more than 50 countries involved in space exploration, "said Shelton, as quoted Spaceof, may 10, 2011. "Currently, more than 20 thousand unused objects are in space," he said.
Currently, said Shelton, 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 garbage that's 10 times more because the sensor that we have currently not able to keep track of all the crap that is," said Shelton.
Horrible, call Shelton, objects become garbage is very dangerous. "They could damage the space systems for military, civil space systems, commercial satellites, and others," he said. "Nobody is immune from the threat that is in orbit at this time," 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 is, remains of testing Anti-Satellite (ASAT) belongs to China in 2007.
"One of these trials has been increasing the number of objects in the debris around 35 percent," said Kaplan. "It gets worse, its location was at an altitude of 865 kilometres, the area most populated where orbiting satellites generally," he said.
Another case, in February 2009, Iridium 33 communication satellite belonging to the UNITED STATES collided with the Cosmos, space shuttle Russia unused, at an altitude similar to China's ASAT test. Consequently, fractional debris more scattered.
"The result of the launch of the satellite during the last 50 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-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 funds, technology does not exist, and there is no cooperation. Nobody wanted to fund that effort, "said Kaplan.
Kaplan added, cleansing of outer space is the ' industry continue to grow ' but no one wants to work on. "In addition, politically, it's also not profitable," he said. (eh)
