Japan's fishing line experiment in space fails to make a catch

Japan's fishing line experiment in space fails to make a catch”

A Japanese team planned to use a 700-meter-long tether to coax floating debris to a lower orbit, where it would burn up in the Earth's atmosphere.

"It is certainly disappointing that we ended the mission without completing one of the main objectives", Inoue added. Bits of retired satellites, metal expelled from rockets, and abandoned equipment make up this ominous cloud of debris.

The National Research Council issued a report in 2011 recommending that NASA create a strategy to deal with space junk, including tracking and possibly removing it from space, National Public Radio reported.

Over 100 million pieces of space junk orbit Earth, 29,000 of which are big enough to cause major damage.

The experiment traveled to space aboard Japan's uncrewed Kounotori 6 HTV spacecraft, which also delivered thousands of pounds of supplies including food, water and hardware to the International Space Station when it docked in mid-December. It's a frustrating setback given the mounting risks posed by the almost two million bits of junk now swirling around our planet.

A few weeks later the Japanese Aerospace Exploration Agency (JAXA) described its comparatively simple and cost-effective plan to magnetically "pull" debris out of orbit with an electromagnetic cable. The general idea is that the electrodynamic tether would attract electrons from the ambient plasma in the upper reaches of Earth's atmosphere and that these electrons could power a "current drive". "Our understanding of the growing space debris problem can be compared with our understanding of the need to address Earth's changing climate some 20 years ago".

For example, in 2009, a dead Russian satellite collided with an operational US satellite, producing about 700 pieces of space junk in the process.

Researchers theorize the should the amount of space junk continue to increase, it will eventually reach of a density where the number of collisions begins to cascade.

On Sunday, the spacecraft and all that rubbish was incinerated in Earth's atmosphere as HTV-6 made a controlled deorbit, safely plunging down over the Pacific Ocean.
