Design of an intake and a thruster for an atmosphere-breathing electric propulsion system
Francesco Romano, Thomas Binderup Jensen
Challenging space missions include those at very low altitudes, where the atmosphere is the source of aerodynamic drag on the spacecraft, that finally defines the mission's lifetime, unless a way to compensate for it is provided. This environment is named ...
2022Numerical studies on saturated kink and sawtooth induced fast ion transport in JET ITER-like plasmas
Mario Ludovico Podesta, Matteo Vallar
This presentation examines the energetic particle transport induced by saturated kink modes and sawtooth crashes in JET deuterium plasmas. It is known that kink mode-resonant transport and phase-space redistribution from sawtooth crashes can drive strong f ...
IOP Publishing Ltd2022Re-entry analysis of critical components and materials for design-for-demise techniques
Pénélope Leyland, Stefano Mischler, Seong-Hyeon Park
The concern caused by the rising population of space debris has increased. One of the recommended mitigation measures is the safe re-entry disposal either in a controlled or uncontrolled manner. Performing a controlled re-entry, where the spacecraft is gui ...
2021The cis-lunar ecosystem — A systems model and scenarios of the resource industry and its impact
Lunar resources is one of the many new putative business models that may transform space logistics. Yet it competes with Earth-based resources, in a complex trade-off involving both tech development & socioeconomic dynamics. This study models the size vs. ...
2021Simulating Enhanced Methane Deliverable Capacity of Guest Responsive Pores in Intrinsically Flexible MOFs
Berend Smit, Matthew David Witman
A novel computational procedure, based on the principles of flat-histogram Monte Carlo, is developed for facile prediction of the adsorption thermodynamics of intrinsically flexible adsorbents. We then demonstrate how an accurate prediction of methane deli ...
AMER CHEMICAL SOC2019A Two Phase Heuristic Approach For The Dynamic Electric Autonomous Dial-a-Ride Problem
Nikolaos Geroliminis, Claudia Bongiovanni, Mor Kaspi
In the Dial-a-Ride-Problem (DARP) a fleet of vehicles provide shared-ride services to users specifying their origin, destination, and preferred arrival time. In the dynamic version of the DARP, some trips are booked in advance while others come in real-tim ...
2018Dressed photon-orbital states in a quantum dot: Intervalley spin resonance
The valley degree of freedom is intrinsic to spin qubits in Si/SiGe quantum dots. It has been viewed alternately as a hazard, especially when the lowest valley-orbit splitting is small compared to the thermal energy, or as an asset, most prominently in pro ...
2017Mission Design and GNC for In-Orbit Demonstration of Active Debris Removal Technologies with CubeSats
Volker Gass, Muriel Richard, Camille Sébastien Pirat, Federico Belloni, Reto Wiesendanger, Christophe Dominique Paccolat
Within the frame of the ESA's General Support Technology Programme, two In-Orbit Demonstration (IOD) missions using CubeSat technologies were studied. These IODs aim at alleviating the technical risk inherent to new technologies required for Active Debris ...
Elsevier2016DEVELOPING A RELIABLE CAPTURE SYSTEM FOR CLEANSPACE ONE
Pierre-Alain Mäusli, Muriel Richard, Camille Sébastien Pirat, Régis Voillat, Timothée Robert Sophus Frei, Xavier Collaud, Bastien Gorret, Michel Lauria
The objectives of the CleanSpace One mission are to raise the awareness of the orbital debris problem, develop and test technologies for non-cooperative rendezvous and as a demonstration, de-orbit the SwissCube satellite. Within this project and over the l ...
2016Mission Design and GNC for In-Orbit Demonstration of Active Debris Removal Technologies with CubeSats
Volker Gass, Muriel Richard, Camille Sébastien Pirat, Federico Belloni, Reto Wiesendanger, Christophe Dominique Paccolat
Within the frame of the ESA’s General Support Technology Programme, EPFL studied two In-Orbit Demonstration (IOD) missions using CubeSat technologies. These IODs aim at alleviating the technical risk inherent to new technologies required for Active Debris ...
