Japan’s experiment on clearing space junk has failed after multiple equipment crashes

JAXA launches magnetic tether to clear space garbage revolving Earth

On the morning of February 6, the JAXA built tether was supposed to start its mission of cleaning the junks around the orbit of the earth. But this mission has been abandoned by the JAXA due to some technical issues. It’s the third time that the Tokyo-based JAXA has faced failure over its space missions.

The scientists from all over the world mentioned their courtesy on the failure of this mission. It is like a moment of embarrassment for Tokyo.  There are various heavy particles moving around the orbit of the earth and it was pretty necessary to clean those particles as they can be a threat for earth at any time. These particles are considered to be small parts of rockets or satellites.

To clean these particles, the JAXA had built a tether which is made up of aluminium and steel wires. The tether was supposed to catch the junks and to burn them in a safe place around the space. This tether was attached to a cargos ship, which used to carry necessary stuff for the astronauts in the space. This cargo ship was supposed to enter the orbit of the earth on the morning of6th February.

But the problem rose when this tether started showing some issues while its deployment. This was known to crew members involved in this mission, just a week before the execution of this mission. But unfortunately, the scientists were unable to solve the issue and finally, the JAXA has abandoned this mission.

This can be termed as the third failure to JAXA. Previously, JAXA had abandoned another mission which was supposed to gather the X-rays emitting from various galaxy clusters and black holes. The mission was cancelled due to the communication gap which increased between the scientists and the spacecraft.

This is not the first time that JAXA is experiencing the performance failure. Last year, the company faced a similar situation by losing contact with a month old launched $270 million satellite and the landing of a rocket into the ocean due to its failure to reach orbit.

In order show how much space pollution we humans have created, Stuart Grey, a scientist and lecturer at the University College London, has made a video which compares the amount of space debris present in 1957 with space chunks in 2015. It was 1957 when Russians launched the Sputnik satellite and released first of the man-made chunk in space. Since then there has been tremendous increase in the numbers and now these numbers have grown so much that they are threatening space projects and more importantly mankind itself.

Every white dot in the video represents a space debris released during space missions. Agencies have started proposing ideas to clear up space chunk before things quickly get out of hand. Moreover, reusable rocket can significantly reduce the number as these satellites do not leave chunks behind.
