The amount of space junk above the Earth has reached the "tipping point". The committee called on the U.S. space agency to take measures to mitigate the impact of space junk.
It is reported that the computer models show that the number of orbital debris in space has more than enough to continue to collide and produce more space junk, threatening the safety of the spacecraft. The report thinks that the space junk is the same issue with greenhouse gases and the nuclear waste storage, the short-term effects is not large. But if not dealt in the long term, in the future it will have a tremendous impact on human society. The current space environment is more dangerous for spacecraft and astronauts.
The National Research Council provided more than 20 recommendations for the U.S. space agency to mitigate and improve the space environment, including cooperation with the U.S. State Department and form legal and regulatory framework to clear the space junk. The current laws prohibit a country collect or recover another country's space objects.
The U.S. Strategic Command's space surveillance network monitored 9949 pieces of orbital debris in 2006. In 2011, this number had risen to 16,094. The diameter of this orbital debris is not less than 10 cm. American Satellite Industry Association's data show that the commercial, military and civilian satellites running over the Earth is about 1000.
In the February of 2009, two satellites of the United States and Russia collide over Siberia, instantly generating a lot of space junk. It has attracted the attention of the international community on the space junk. Experts believe that as human spaceflight activities increase, the number of space junk will continue to increase. Countries that use space must seriously consider the national problem of space junk. But technically speaking, recycling space junk is difficult to achieve in the short term.
The U.S. National Research Council (http://www.himfr.com/buy-photo_frame_fridge_magnet/) points out that the U.S. State Aviation Administration must develop a new strategic plan, to ease the threat of rocket debris, waste satellites and thousands of other small junk. These space junk are flying around the Earth at a speed of 28,164 kilometers per hour.
According to the data, the wreckage endangers around 1000 commercial, military and civilian satellites running on the Earth's orbit. The revenue of the global satellite industry is $ 168 billion last year. However, the analysts say that the recycling of space junk is still a problem we need to solve.
