## What is Orbiter Waste?

Most orbital debris is in near-Earth orbit, where the space station is moving.

Orbital debris, sometimes called space debris, is scrap metal that orbits the earth or can be pieces of spacecraft.Â Humans have been throwing objects into space for more than 50 years.Â Most of these objects have fallen to the ground.Â Most bodies that have fallen to the ground have fallen into the water, as 70% of the earth is made up of water.Â However, a large number of objects sent into space are in orbit around the Earth.

### What is the size of the orbiter waste?

In the most severe case, it can be as small as points of paint or metal fragments separated from the spacecraft.Â Large debris, on the other hand, can be a complete satellite outage.

The usual source of orbiting debris larger than one centimeter is the explosion of objects orbiting the earth.Â This type of waste is often the propellants upstream of the rocket, which can carry high-pressure fuel or liquid.

### Why is orbiting waste important?

Most space debris travels very fast, which can reach speeds of up to 4.3 to 5 miles per second.Â 5 miles per second equals 18,000 miles per hour.Â Such a speed is 7 times faster than the speed of a bullet.

If a spacecraft is moving toward space debris, their final velocity when colliding with each other can be even higher.Â The average speed of a piece of space debris moving toward another object is 22,370 miles per hour.Â Because a piece of space debris moves very fast, it causes a lot of damage.Â The intensity of a collision with a piece of space debris moving at a speed of about 6 miles per second can be as severe as a collision with a bowling ball moving at a speed of 300 miles per second.

### How much waste is in the circuit?

To keep astronauts safe, scientists are using radar to track all debris in orbit.Â Space debris is classified according to its size.Â About 13,000 known objects are more than 10 cm in diameter.Â Scientists believe that more than one hundred thousand roundabouts are between 1 and 10 centimeters.Â Tens of millions of pieces are smaller than one centimeter.Â All debris larger than 10 cm has been accurately tracked by radar and telescopes.Â The information obtained from these traces is used to estimate the amount of small waste.Â Although scientists are not able to track all the waste, they are aware of the total amount of waste.

Experiments such as the Long Duration Exposure Facility have helped scientists better understand space debris.

Scientists are studying the space shuttle returning from the orbit to estimate the amount of debris smaller than one millimeter in orbit.Â When the space shuttle returns from the mission, the scientists count the blows to the shuttle.Â They then compare the number of depressions and cavities with the amount of space the shuttle has traveled.Â Scientists use these comparisons to estimate the number of small objects in Earth orbit.Â NASA has conducted experiments to identify as much orbital debris as possible.Â Satellites such as the Long Duration Exposure Facility have been returned to Earth.Â Scientists then count the objects that have damaged the satellite.Â LDEF was in space for 5 years.Â What happens to materials in space was also examined.

### How do astronauts stay safe from orbiting garbage?

Because NASA has tracked large debris, the spacecraft with its occupants can escape.Â When an object is expected to arrive on the International Space Station, NASA can avoid colliding with it with a slight change in the station’s path.Â In addition, the space station has the hardest protection shield among spacecraft and is able to withstand the impact of the smallest debris.Â Garbage hits panels that protect vital parts of the space station.Â When astronauts are outside the space station, their space suits protect them from orbital debris and meteorites.Â The costumes have a hard layer of thin material that protects astronauts from impact.Â This layer is made of the material used in bulletproof vests.

Since fine particles of waste can not be traced, it is possible to deal with them.Â The space shuttle often returns with cavities caused by small impacts.Â In addition, blows may result in small cracks in the front windows.Â The windows are replaced after each mission.Â The shuttle has a three-layer window to protect the occupants.

The multi-layered material in the space suit protects astronauts from being damaged by orbital debris during space travel.

### What is NASA doing about orbital waste?

The more humans throw objects into space, the more Earth orbit will become a crowded and dangerous dump?Â Space agencies around the world have taken steps to prevent this from happening.Â Since 1988, the United States has adopted a formal policy to reduce waste generation.Â NASA also has an office called the Orbital Waste Program at Johnson Space Center in Houston, Texas.Â This office is looking for a way to get rid of garbage in space.Â Many US aerospace airlines follow waste reduction strategies.

Russian, Japanese, French and European space agencies are reducing waste production.Â NASA and other space agencies have taken many steps to reduce the problem of orbital debris.Â Upstream thrusters of spacecraft and some satellites are in downstream orbits.Â This placement leads to their return to space and their early burns.Â Garbage in orbits below 373 miles usually falls to the ground within a few years.Â Objects at altitudes of more than 621 miles can survive in orbit for more than a century.
