A Viable Orbital Debris Mitigation Mission using Active Debris Removal
… environment contains a growing number of orbital debris objects. This growing orbital debris population increases collision probabilities between both orbital debris and functioning satellites. A phenomenon known as Kessler Syndrome can be induced if these collisions occur. Kessler Syndrome states …

Self Balanced Bare Electrodynamic Tethers. Space Debris Mitigation and other Applications
… together in several space applications: from mitigation of the space debris to capture in a Jovian orbit. The computation of the electron collection by a bare tether is faced in first place. The semi-analytical method derived in this work allows to calculate accurately and efficiently the …

Detection of energetic neutral flux emanating from extreme ultraviolet light lithography sources
… One such hurdle is the existence of energetic debris emitted by the dense warm plasmas (~1019cm-3, ~30 eV) used to create the EUV light. EUV’s high absorbance into most known materials prevents the traditional use of a pellicle to protect the collection optics, which reflect the produced light …

Orbital debris : drafting, negotiating, implementing a convention
… commercial activity. Moreover, the existing mitigation guidelines remain voluntary and are not legally binding under international law. As a result, space debris tends to accumulate and remains in orbit for a long period of time. A space debris convention is thus warranted. The proposed …

Incentivizing Collaboration on Space Sustainability: Detectability, Identifiability, and Trackability of Space Missions
… between active payloads or with pieces of debris rises exponentially. One of the initiatives to combat congestion is the Space Sustainability Rating. The Space Sustainability Rating is a rating system commissioned by the World Economic Forum in 2018 that scores a space mission on how …

Removal of tin from exterme ultraviolet collector optics by an in-situ hydrogen plasma
… degrade the quality of collector optics. The mitigation of this debris is one of the main problems facing potential manufacturers of EUV sources. which can damage the collector optic in three ways: sputtering, implantation, and deposition. The first two damage processes are irreversible and …

In Space Reverse Logistics
… design for mitigating and remediating space debris in proliferated Low Earth Orbit (pLEO) constellations. The ISRL design aims to collect defunct satellites from their operating orbits and to bring them to a Workshop Space Station (WSS) for centralized on-orbit servicing (OOS). A modular …

Versatile Inference Algorithms using the Bayes Tree for Robot Navigation
… in-space robotic assembly, and orbital debris mitigation. A key requirement shared among such space missions is the capability to carry out robust and autonomous close proximity operations between the involved agents. Scenarios involving unknown and uncooperative target objects require …

Magnetic mitigation of energetic ions for extreme ultraviolet lithography sources
… degrade the quality of collector optics. The mitigation of this debris is one of the main problems facing potential manufacturers of EUV sources. The use of magnetic fields to deflect ionic debris has been proposed and is investigated here. In this thesis, a detailed computational model of …

Debris Characterization And Mitigation Of Droplet Laser Plasma Sources For Euv Lithography
… by deposition and ablation from the plasma debris. Realization of a high CE but low debris plasma source is possible by reducing the mass of the target, which is accomplished by using tin-doped droplet targets. These have sufficient numbers of tin atoms for high CE, but the debris generation …

Sun-Synchronous Orbit Slot Architecture Analysis and Development
<p>Space debris growth and an influx in space traffic will create a need for increased space traffic management. Due to orbital population density and likely future growth, the implementation of a slot architecture to Sun-synchronous orbit is considered in order to mitigate conjunctions among …

Diagnosis of the flux emanating from the intermediate focus of an extreme ultraviolet light lithography source
… pressure, buffer gas mass, and pinch gas mass on debris transport will be explored using the XTREME XTS 13-35 EUV light source. Utilizing the Sn Intermediate Focus Flux Emission Detector (SNIFFED), three triple Langmuir probes, as well as a set of Si witness plates placed along the mock-up …
