A large space debris weighing several tons is currently in the uncontrolled reuse phase (the site is spoken of as “out of control”), and parts of it Is expected to fall to the ground In the next few weeks.
If it is not worrying enough, it is not possible to predict exactly where the unburned pieces in the atmosphere will land. Given the object Around the circular path, Possible landing points Anywhere In the latitude group “slightly farther than New York, Madrid and Beijing and south of Chile and wellington, south of New Zealand”.
The Garbage Long is part of the March 5B rocket, which recently successfully launched China’s first module for its proposed space station. The incident comes a year after another similar Chinese rocket Fell to the ground, Landed in the Atlantic Ocean, but it is not said to have left a trail of debris in the African nation of C டிte d’Ivoire.
At the time, experts noted that it was one of the largest man-made debris to fall to Earth. We can’t say for sure what fate awaits this latest space junk.
Garbage from space
Australia has already set a record in the category of “who can be affected by the biggest space debris”. In 1979, 77 tons of U.S. Space station Skylab Disintegrated over Western Australia, Pepper the areas around the southern coastal city of Esperance.
At the time, the event was full of excitement and light-heartedness, and many pieces were collected by space enthusiasts. The Esperance Shire Council has easily released NASA Good for littering, And an American radio station then raised enough money to pay off the debt.
While there are no recorded deaths or serious injuries from victims of space debris, there is no reason to think it is not dangerous. A year before Skylab’s death, a Soviet Remote sensing (Spy) satellite, Cosmos 954, Collapsed into a barren zone In the northwestern regions of Canada, it spreads radioactive debris over several hundred square kilometers.
As the Cold War was at its peak, the sensitivity of nuclear technology on board the Cosmos 954 led to the unfortunate delay in finding and cleaning up the rubble due to distrust between the Soviet Union and the Canadian / American rescue efforts.
The clean-up operation took several months, but only a fraction of the debris has formed. Canada paid more than C $ 6 million to the Soviet Union and spent millions more, but eventually paid only C $ 3 million.
Since the late 1970s, pieces of space debris have been constantly coming to Earth, and they are being viewed with great interest. Of course, more than 70% of the earth is covered by the oceans, and only a small fraction of the remaining 30% is covered by your home. But for anyone who mistakenly minimizes very long conflicts, the consequences can be truly devastating.
It is a wonder of fate that Cosmos 954 did not land in Toronto or Quebec City, where a radioactive fall would have been necessary for a large-scale eruption. In 2007, pieces of debris from a Russian satellite The Chilean passenger plane missed very little Flies between Santiago and Auckland. As we send more objects into space, the chances of an accident increase.
Who pays to clean up the mess anyway?
International law lays down a compensatory rule applicable in many situations of damage to the earth, as well as when satellites collide in space. The 1972 Responsibility Conference, A UN. The treaty imposes responsibility on the “launch states” for damage caused by their space objects, including a full liability regime when they crash into the earth as debris.
In the case of Long March 5b, this would impose potential liability on China. This agreement has been implemented only once before (For the Cosmos 954 incident) Should therefore not be considered a powerful opposition. However, it is likely to operate in a more congested space environment in the future, with more uncontrolled returns. Of course, this framework applies only after damage has occurred.
Other international guidelines related Garbage reduction And Long-term sustainability of space operations Setting voluntary standards aimed at controlling the probability of collisions in space, and minimizing the breakdown of satellites during or after their missions.
Some satellites can be moved to a Cemetery Orbit At the end of their operational life. While it works well for certain orbits at relatively high altitudes, starting to move most satellites between orbital planes is impractical and risky. Most of the millions of space debris that has been orbiting uncontrollably for years, or if they are in low Earth orbit, gradually descend to Earth, burning in the atmosphere before coming into contact with terra firma.
A globally integrated space transport management system would be crucial to avoid collisions that could cause the satellites to lose control and cause them to fall helplessly into orbit or fall to Earth.
Monitoring the operation and operation of each satellite in detail is harder than it sounds, because countries must be prepared to share the information they currently consider to be the secret of national security.
But, in the end, global cooperation is essential if we are to avoid our sustainable future Location Activities. In the meantime, don’t forget to look up now and you will find the most amazing rubbish on the planet.
