  1. 1. Juice/JDC ion measurement perturbations caused by spacecraft charging in the solar wind and Earth’s magnetosheath

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Derek van Winden; [2024]
    Keywords : Juice; Jupiter Icy Moons Explorer; JDC; Jovian plasma Dynamics and Composition analyzer; Particle Environment Package; PEP; Jupiter; Ganymede; Callisto; Europa; solar wind; magnetosheath; spacecraft charging; Spacecraft Plasma Interaction Software; SPIS; charging; plasma; measurement perturbations; perturbation; distortion; particle detector; Institutet för Rymdfysik; IRF; Dublin Institute for Advanced Studies; DIAS; European Space Agency; ESA;

    Abstract :  In July 2031, a new chapter in the exploration of the Jovian system will begin with the arrival of the Jupiter Icy Moons Explorer (Juice) at Jupiter. Launched on April 14 2024 as part of ESA’s Cosmic Vision programme, the mission aims to study Jupiter and its icy Galilean moons Callisto, Europa, and Ganymede. READ MORE

  3. 2. Plume-Spacecraft Interaction Analysis : Study on the Plume Effects of Hall-Effect Thrusters (HET) and High-Efficiency Multistage Plasma Thrusters (HEMPT).

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Josep Sentís Garzón; [2023]
    Keywords : Electric propulsion; Plasma plume; Plasma physics; SPIS; OpenPlume EP; Modelling; Charge-Exchange Collisions; Elektrisk framdrivning; Plasma plym; Plasmafysik; SPIS; OpenPlume EP; Modellering; Laddningsväxlingskollisioner;

    Abstract : Plume-spacecraft interactions play an important role in the performance and integrity of spacecraft during their missions in space. The study encompasses a thruster’s plume simulation and its impact on spacecraft geometries to understand and predict the effects and consequences of the impingement on spacecraft surfaces, such as erosion, contamination, forces, and torques.

  4. 3. Internal charging modelling of the AMBER instrument on-board Jason-3 spacecraft

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jeremie Hacquart; [2020]
    Keywords : Internal Charging; Satellite; Plasma; SPIS; Intern laddning; satellit; plasma; SPIS;

    Abstract : Internal charging is the accumulation of charged particles inside a material. Thisbuild up represents a serious hazard to satellites and instruments exposed to thespace environment. The Van Allen radiation belts constitute one of the worst spaceenvironments for satellites orbiting the earth. READ MORE

  5. 4. Intake Design, and Optimization for an Atmosphere- Breathing Electric Propulsion System

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jesus Espinosa Orozco; [2020]
    Keywords : Atmospheric Intake; ABEP; Electric Propulsion; Plasma; VLEO;

    Abstract : Over the last two decades, Very Low Earth Orbit (VLEO) has gained researchers attention as it provides a significant amount of benefits in the field of earth observation and telecommunications. VLEO provides increased payload performance, improved geospatial accuracy, lower launch mass, simplified end of life disposal, and they reduce space-debris collision risk. READ MORE

  6. 5. Numerical simulation of the electric propulsion’s effects on the spacecraft

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Nguyen van Sang; [2018]
    Keywords : ;

    Abstract : As electric propulsion is now the focus in the space industry, its negativeeffects on the spacecraft have yet to be fully understood. Indeedthis type of propulsion deeply modifies the ambient plasma surroundingthe spacecraft and can affect severely many subsystems by erosion,charging or contamination. READ MORE
