Experiment of Diffuse Reflection Laser Ranging to Space Debris and Data Analysis

, 2014
Space debris has been posing a serious threat to human space activities and is needed to be measured and cataloged. As a new technology of space target surveillance, the measurement accuracy of DRLR (Diffuse Reflection Laser Ranging) is much higher than ...

Mitigating orbital debris in LEO with high power pulsed laser [PDF]

, 2014
There is a large amount of space debris in the size range of 1 to 10 cm that is orbiting the Earth at a very high velocity which could do tremendous damage to any space mission if it were to collide.

LEO space debris mitigation using laser ablation [PDF]

, 2014
Since the first spacecraft was launched in 1957 a great number of spacecraft have been put into orbit and a significant fraction of these are still orbiting the Earth as inert vehicles or space debris.

Improved orbit predictions using two-line elements

, 2010
The density of orbital space debris constitutes an increasing environmental challenge. There are three ways to alleviate the problem: debris mitigation, debris removal and collision avoidance.

Removing Orbital Debris with Lasers

, 2011
Orbital debris in low Earth orbit (LEO) are now sufficiently dense that the use of LEO space is threatened by runaway collisional cascading. A problem predicted more than thirty years ago, the threat from debris larger than about 1 cm demands serious ...

Active Debris Removal Mapping Project [PDF]

, 2014
Space debris discussions initiated with the start of the space age 55 years ago and have seen special interest in current years. This is due to the large increase in the number of space debris which has led to an increased threat of collision with ...

Observing planet-disk interaction in debris disks [PDF]

, 2012
Context. Structures in debris disks induced by planetdisk interaction are promising to provide valuable constraints on the existence and properties of embedded planets. Aims.

Orbital Debris-Debris Collision Avoidance

, 2011
We focus on preventing collisions between debris and debris, for which there is no current, effective mitigation strategy. We investigate the feasibility of using a medium-powered (5 kW) ground-based laser combined with a ground-based telescope to ...

The HR 4796A Debris System: Discovery of Extensive Exo-Ring Dust Material [PDF]

, 2017
The optically and IR bright, and starlight-scattering, HR 4796A ring-like debris disk is one of the most (and best) studied exoplanetary debris systems.
