Japanese experiment proves that cleaning up space junk is hard

Scientists at the Japan Aerospace Exploration Agency (JAXA) were trying to test an experimental system in which a long cable would be deployed from the Kounotori 6 satellite and directed toward a piece of space debris. The tether was supposed to generate electricity by swings through the Earth's magnetic field, which it would use to slow down space junk until it was pulled it into a lower orbit where it would ultimately burn up.

Although the vessel successfully sent supplies to astronauts at the International Space Station, it could not clear the debris, reported IANS. Even a tiny piece of space debris could damage or destroy critical equipment when it's moving at extreme speeds. It's a frustrating setback given the mounting risks posed by the almost two million bits of junk now swirling around our planet.

While this test failed, it is likely that JAXA, and other space agencies, will continue to test different methods of removing space junk from orbit. Over 100 million pieces of junk have been left in orbit since we started exploring space about 60 years ago.

Letter, 2/6: Demand vote against DeVos
A filibuster attempt was already defeated early Friday morning when the Senate voted 52-48 to move forward with DeVos' final vote. Harry Reid (D-Nev.) opted to change the Senate rules to require only 51 vote to end debate for a confirmation.

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

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. At the moment, NASA tracks about 500,000 pieces of space junk the size of a marble or larger to make sure these pieces of debris don't threaten any needed satellites or spacecraft in space.

An experimental Japanese mission to remove unsafe debris from orbit has ended in failure.

Thomas led the Boston Celtics sixth straight win against Lakers
Maybe Thomas can finagle another sit-down chat like the one he had when Bryant played his final game at TD Garden a year ago . In Boston's final possession of the second quarter, a roar rose up all around as he dribbled nonchalantly between his legs.

After a week of attempts to get the experiment to work, JAXA was forced to give up and abandon the test.

"We believe the tether did not get released", said lead researcher Koichi Inoue in a press conference.
