A ground-based laser tracking system that could help to stem the accumulation of space debris is being developed in the UK.

ESA Releases Space Debris Report

In order to address the issues posed by space debris on spaceflight activities UNCOPUOS has taken the initiative to create a set of internationally agreed guidelines for the long-term sustainability of outer space activities.

Dealing With Space Debris

With more than 750 000 pieces of dangerous debris now orbiting Earth, the urgent need for coordinated international action to ensure the long-term sustainability of spaceflight is a major finding from Europe's largest-ever conference on space debris.

Earth is surrounded by a cloud of space debris. This material ranges from dead satellites and rocket stages to fragments of material and even flecks of paint... and all this junk could do enormous damage to working satellites.

Copernicus Sentinel-1A Hit By Space Debris

ESA engineers have discovered that a solar panel on the Copernicus Sentinel-1A satellite was hit by a millimetre-size particle in orbit on 23 August.

The European-built Cupola was added to the International Space Station in 2010 and continues to provide the best room with a view anywhere.

Developing Anti-space Debris Technologies

ESA is teaming up with Europe's satellite makers and equipment suppliers to evaluate candidate technologies to prevent the generation of space debris in key orbits by future space missions.

ESA's goal of removing a derelict satellite from orbit is picking up pace, as a mission design is assembled to be put before European ministers next year for approval.

Video: Space Debris In Motion

The animation depicts the distribution and movement of man-made objects orbiting Earth.

Do We Need a Space Traffic Cop?

At 10:00 am tomorrow (Friday, May 9) the Space Subcommittee will hold a hearing titled Space Traffic Management: How to Prevent a Real Life 'Gravity'.

"NASA estimates more than 500,000 pieces of hazardous space debris orbit the earth, threatening satellites that support peacekeeping and combat missions. These objects include spent rocket stages, defunct satellites and fragments from other spacecraft that are the result of erosion, explosion and collision. A collision between one of these small pieces of debris and a satellite could release more than 20,000 times the energy of a head-on automobile collision at 65 mph. To help address the threat, DARPA created SpaceView, a space debris tracking project that provides amateur astronomers with the means to make a difference. Amateur astronomers will have their first opportunity to sign up in person for the program at the Arizona Science and Astronomy Expo in Tucson, November 10-11, 2012." More

On-orbit servicing (OOS) and active debris removal (ADR) are part of an emerging category of future on-orbit activities that are critical for taking the next leap in our use of Earth orbit.

ISEC Releases its First Position Paper

The International Space Elevator Consortium (ISEC) has released its first position paper titled Space Elevator Survivability Space Debris Mitigation in the form of a 76 page self-published book. Authored by Cathy Swan, Peter Swan and Robert "Skip" Penny the report states unequivocally that space debris will not be a show stopper for the space elevator.

"The International Space Elevator Consortium has placed this position paper as a recognition that the space debris problem is an engineering one and can be mitigated. The question: "Will space debris be a show stopper for space elevators?" is answered emphatically. NO! The mitigation concepts presented change the issue from a perceived problem to an engineering concern; but, by no means is it a significant threat. This pamphlet illustrates how the development office for a future space elevator can attack this problem, predict probabilities of collision, and convert the concern into another manageable engineering problem."
