Space environment does concern you


Only few people know that space environment is deteriorating. Most of us are not even aware of space environment problems.


It is difficult to realize it in our ordinary life, but modern society is deeply dependent on space technology. Not only satellite communications or other network infrastructure, but everything from the monitoring of forest fires to exploration of underground resources is based on satellite.


And all expected challenges such as lunar base or Mars exploration are definitely the key for mankind's future evolution.


However, the space environment which is so important for us, is facing a grave crisis. This crisis is caused by what we call space debris.


This collection of defunct objects in orbit around Earth flying at a much higher speed than bullets, is becoming a serious threat for space development.


At ASTROSCALE, we are working on different subject to resolve the problem of space debris to "SWEEP THE SPACE FOR OUR FUTURE".

The threat of space debris


The degradation of space environment is caused by what we call space debris.


Near the earth’s orbit, there are approximately 29,000 observable pieces of debris with diameters greater than 10cm. And there are several hundreds of thousands of unobservable ones that are under 10cm and greater than 1cm in size. For those smaller than 1cm, the number is estimated to be about hundreds of millions to trillions (as of 2013). These are all flying around at a speed of 8km per second, which is 20 times faster than a bullet from a pistol. Because of that speed, they can cause destructive damage to satellites and space stations in case of collision.


You might think that there is no need for concern as space is vast. However, there are currently already 10 incidences of “near-misses” per day, where a piece of debris approaches to closer than 50m. And these are just the ones that we can observe. The tragic thing is that collisions between large debris fragments are predicted to take place once every 5 to 9 years from now on. Each collision creates several thousand new pieces of debris. In February 2009, a Russian and American satellite collided with each other. In January 2013, a piece collided with a Russian satellite, which became defunct.


The situation is changing such that it is more of a miracle for satellites to be able to continue orbiting without colliding with space debris. It is said to have reached the stage where the increase in the number of debris is accelerating, and if things are left to stand, it will no longer be possible to use space.



Space Debris - How It Got There, What To Do About It?

Experts have estimated that there are 29,000 objects 10 cm or larger orbiting Earth. Only 7 percent are working satellites. This video explains about the actual situation of space debris and why exactly this is a threat for space development.
