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 ...

Re-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 ...

The cis-lunar ecosystem — A systems model and scenarios of the resource industry and its impact

Jean-Paul Richard Kneib

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. ...

A 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 ...

Mission Design and GNC for In-Orbit Demonstration of Active Debris Removal Technologies with CubeSats

Volker Gass, Muriel Richard, Camille Sébastien Pirat, Reto Wiesendanger, Federico Belloni, 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 ...

ELM-wall interaction on JET and ITER

Richard Pitts

Significant interaction of ELM filaments with the vessel wall is now observed on JET by several diagnostics. To interpret the experimental data, a model of ELM-filament evolution was developed, with the radial velocity taken from experiment and the decay o ...
