These fragments of man-made debris remain a serious threat to various satellites and spacecraft. Four Japanese companies are increasingly working to clear such debris and see better business opportunities. The debris of many satellites launched into space has accumulated. These debris is circling the earth.
The situation is that if a new satellite collides with these debris, then not only will there be crores of losses, but the research project will also be incomplete. These fragments of man-made debris remain a serious threat to various satellites and spacecraft. Four Japanese companies are increasingly working to clear such debris and see better business opportunities. They are working on developing solutions that will make space travel more secure in the coming days.
In fact, debris continues to grow in an attempt to make inroads into space. Most countries are leaving more and more satellites in space. In such a situation, it is believed that in the coming time the amount of such debris in space will increase further. Debris in space is orbiting the Earth at a speed of eight kilometers per second. Debris made by hitting satellites travels at a speed of 40 thousand kilometers per hour. A peanut grain rotating at such a speed also has a grenade-like effect. The waste of space is also a threat to life on the earth.
The Japanese company Astroscale was formed in 2013 and has four branches in the UK, US, Israel, and Singapore. On 22 March this year, the company started its ‘End of Life Services’ through its Elsa-D demonstration craft sent from the Baikonur Cosmodrome in Kazakhstan to the abandoned Soyuz rocket. Elsa-D is made up of two satellites that are connected one above the other. It has a 175 kg ‘servicer satellite’ and the other is a 17 kg ‘client satellite’. It also has a magnetic ‘docking mechanism’ and it is through this satellite that the removal of spoiled satellites and large pieces of debris is carried out.
Apart from Japan, the European Space Agency (ESA) is also working to clean up the litter in space. She is preparing to launch a garbage robot in 2023. This space robot will have a hand that will hold the satellite and brings it back to Earth. Several measures have been worked to clean this waste. Scientists are of the opinion that the waste should be burnt in the space itself. Germany’s space agency DLR is developing laser technology for this. The debris will be consumed by the laser beam.
NASA working on ‘Electro Net’
US space agency NASA is also working on an ‘electro net’. This trap will trap the waste present in a large area and bring it back to the earth’s atmosphere. Much of the waste will burn itself as it enters the Earth’s atmosphere, but there is still concrete work to be done on this idea. In addition, Japan’s space agency Jaxa has a proposal for ‘Electrodynamic Mine’. The seven hundred meters long electrodynamic tunnel will be made of stainless steel and aluminum. This tunnel will slow down the speed of the waste and push it slowly towards the atmosphere.
