The Problem Of Space Debris Keeps On Growing

Daily Mail: See decades of space debris swarm the Earth in 60 seconds: Video reveals how the planet's orbit has become a 'junkyard'

* Video shows decades of debris ringing the planet in just one minute
* Earth's orbit is a spacecraft junkyard and has been steadily growing
* UCL researcher animates 20,000 pieces of junk amassing around Earth

It is difficult to keep track of just how much stuff we throw away each day, but imagine trying to capture that on a global scale, for almost sixty years, and in space.
A new video has achieved this staggering feat by visualising decades of space debris as it accumulates around the Earth.
Dr Stuart Grey, a lecturer at University College London, generated the visualisation which captures the accumulation from 1957 through to 2015.

Is Space Junk A Threat To National Security?

Space Clutter a Growing Concern for Pentagon -- Military.com/Stars and Stripes

Space may be the final frontier, but it’s turning into a rough neighborhood — a limited number of Earth orbits increasingly crowded with satellites and littered with debris that can destroy valuable space assets.

Overcrowding in space is now a national security threat, experts say. U.S. Defense and State Department officials are grappling with the challenge of cleaning up the mess and encouraging “best practices” without compromising national defense.

My Comment: Hmmmm .... one can only imagine the mess that will be produced if an armed conflict did occur in space. One side may win the war .... but be unable to use space for years (if not longer) because of the debris fields.

NASA Tracking Space Debris In Space Station's Path

This handout illustration image created by Australia's Electro Optic Systems (EOS) aerospace company shows a view of the Earth with low-orbiting space debris. The US space agency is tracking a piece of space junk that could be on a path toward the International Space Station, where the shuttle Atlantis has just docked on its final mission, NASA said.

From Yahoo News/AFP:

The US space agency is tracking a piece of space junk that could be on a path toward the International Space Station, where the shuttle Atlantis has just docked on its final mission, NASA said Sunday.

However, NASA is not ready to say for sure whether the object is projected to collide with the shuttle and station, though the paths were likely to cross on Tuesday, said deputy manager of the space shuttle program LeRoy Cain.

"What we were told today is very preliminary," Cain said. "It is a potential right now."

Collision Course: The Need for Better Space Junk Regulations

From Popular Mechanics:

With 3000 satellites and a growing arsenal of space junk, Earth’s orbit is a crowded area. If debris continues to accumulate, low Earth orbit could eventually become too congested for safe satellite use and space travel. Unfortunately, space junk is hard to regulate and even harder to clean up. Here’s an overview of existing space junk laws and some proposals for addressing the problems with debris in space.

Close calls in orbit happen all the time—scientists estimate that launch vehicles and other objects come within striking distance of one other over 1000 times a day. So when tracking reports on Feb. 10, 2009, predicted that Iridium 33, a 12-foot-long, 1200-pound communications satellite, and a 1-ton Russian military sat, Kosmos 2251, would pass within less than half a mile of each other, no one was alarmed. It wasn’t the closest call predicted for that day, or even the closest pass for any of the 66 Iridium satellites that coming week. But at the time of the predicted approach, Iridium 33 fell silent.

Shuttle Dodges Space Junk Risk

From Wired Science:

Despite the recent rash of space-debris problems, the risk that the space shuttle mission to service the Hubble Space Telescope will have a catastrophic collision with space junk and micrometeoroids won't exceed NASA guidelines.

NASA said Thursday the new orbital debris risk for STS-125 had fallen to 1 in 221. A couple of precautionary maneuvers -- in particular coming into a lower, less crowded orbit on the 10th day of the mission and using Hubble as a shield -- reduced the spaceship's chance of getting hit with a stray paint chip or metal bolt.
