Space Pollution and Future and Solution: Where does the garbage come from?


On Earth, of course! Or that would be the answer you are waiting for! Though it seems like a title from SF films, space trash will become a burning subject in the future. Mankind has already filled the oceans with tons of waste and plastics, some recyclable in millions of years. It's not just a worrying topic, it's about human's footprint on the environment. And if we started to put our fingerprint and the immense space, where do we get?

Are we thinking of the cases of those long-haul planes throwing frozen shit out of the heights? Or the vast abandoned satellites that are rolling in Earth's orbit? If we reached the highest peaks and visited the deepest crevices of the oceans, space is the last frontier, right? Movies such as Thor: Ragnarok and Intergalactic Motorway Guide, Armageddon or Gravity.

When I was little watching the stars. It sounds like the beginning of the movie Barbati in Negru. Then I read the first SF books. And I saw movies in which huge spacecraft, cargo ships, unloaded huge amounts of space rubbish on a distant planet. It's an image that keeps you on the retina for a long time. Maybe that's our future?

Most importantly, before we think about the future or solutions for the future, let's look at the figures.

More than 4,600 satellites are now orbiting our planet. Not to mention over 14,000 old missiles and other pieces of space stations, dead satellites, and more. The countries that have left most of the space trash are America, Russia and China. If we keep it so soon, we will not be able to leave Earth due to collisions.

Space rubbish is dangerous. And not just for astronauts, space stations and missions. But for the earth. A single collision in space can create thousands of space debris that will turn hundreds of years into space. At this time there are over 170 million space rubbish that spills around the Earth for thousands of miles, according to the European Space Agency. There is already a database that investigates these objects.

History of Artificial Satellites and Spatial History

The first artificial satellites launched by man on Earth were the work of the Soviets. The first satellite was named Sputnik and was launched by the USSR on October 1 - 4, 1957. He orbited the Earth's orbit at a distance of 900 km. The satellite was 83 kg. Two months after the Americans failed to send space to the Vanguard satellite.

On November 3, 1957, the Sputnik 2 satellite was launched into space with the first living being who orbited the Earth: a bitch, Laika. Sputnik 1 has been used to measure temperature and pressure in space. Sputnik 2 measured solar and cosmic radiation.

The first man in space was Yuri Gagarin on April 12, 1961 with Vostok 1. A month later, on May 5, 1961, Alan Shepard became the first American in space.

The first space mission that returned home successfully was Apollo 8: Frank Borman, James Lovell and William Anders. This is about the unseen face of the moon.

The first people on the Moon were Neil Armstrong, Michael Collins and Buzz Aldrin with Apollo 11 on July 16, 1969.

How to clean the garbage

Some Chinese scholars have already come up with an idea of ​​how to get rid of space rubbish. And we will not send him to a desert planet. Several space agencies collaborate to remove space debris around Earth's orbit. So, they have been thinking of new technologies and even spacecraft to handle the removal of space trash. The projects were encouraging, but also very avant-garde. From spacecraft with cleaning systems to technologies that can carry or collect the old space remnants. And the Chinese have gone a long way before finding a solution to get rid of shipwrecks and the use of a space laser.

Kessler syndrome has already been discussed. It talks about garbage collection in space so large that any collision will trigger a chain reaction. Thus, taking off Earth will become impossible.

The Space Center of the University of Surrey has set up a mission to try to clean up space. First, the RemoveDebris, will use a small satellite with a net and test a harpoon to collect the garbage. The satellite looks like a washing machine.

Scientists estimate over 7,500 tonnes of space trash that can reach the critical point. Scientists at the University of Southampton believe this type of trash can become an environmental catastrophe. They can destroy our satellites, damage or destroy space stations, even if they are invisible.

In 2012, a European satellite called Envisat, as two upstairs buses, stopped without reason. Since then, the Earth has been orbiting. Navigations, communications, weather forecasts, everything would have affected Earth. In terms of technology, it would mean going back for decades.

Until 2025, several thousand satellites are scheduled for launch into orbit. If you look at the Throne Wreath or weather forecast, the chances are very high that behind the technology is a satellite.

There are already two government agencies in America dealing with the tracking of space rubbish. This is a NASA group and Stratcom, an agency that oversees over 24,000 objects and the danger it poses. There is a radar called "S-Band Space Fence," a kind of space fence that warns when objects are approaching. The radar is located in the Marshall islands and operates on microwaves.
Space fences and landfills for garbage

Although space does its job trying to clean itself, people try the same thing. Even if we are trying not to send anything in space, the disaster would still hit us at some point. Satellites, for example, should be "recalled" after 25 years of activity. But they do not "work" all by the rules. The Chinese even decided in 2007 to shoot them down using missiles. You can figure out what space chaos has been created.

Scientists have proposed several solutions. Among these, the concentration of solar radiation for the destruction of small space debris. Like a huge magnifying glass. The European Space Agency would like to "capture" space debris in a super-fine net with a robotic arm. Or perhaps even "harnessing" space debris with a harpoon. The most SF idea came from the Chinese who want to use a space laser

Thousands of altitude, some space debris moving at 28,000 km / h, you have to be very precise. That's how Earth looks from above. A pattern that shows us what kind of space waste is spinning and attracted to Earth's orbit. A rather daunting future if we think of axle changes, chain collisions or meteor shower.

In 2015, the Japanese wanted to add an orbital laser to the International Space Station. Its purpose was the destruction of the space debris that had already destroyed some of the station's windows.

Less than 2,000 km from Earth, the debris is denser than the meteorites. And by scrap we even understand powder from missile engines, paint and frozen scraps. For example, the space station is orbiting 300-400 km from Earth, and the collisions of the satellites in 2009 and 2007 happened at 800-900 km from Earth.

Besides the "usual" objects of the space missions, weapons were also lost. In 1960, Americans lost an anti-satellite weapon launched against the Soviet Union.
What kinds of things were lost in space?

The quantities and the diversity of objects lost in space, or intentionally left, is amazing. Whole ships, missiles, satellites. But these are already elementary. Electric blankets, astronaut objects, a lost gauntlet at the first landing, a lost room next to Gemini 10, garbage bags lost by Soviet cosmonauts, gates and instruments, solar panels, and more. Even American money, excrement bags and golf balls launched by Alan Shepard.
