Observations of the spatial and temporal structure of field-aligned beam and gyrating ring distributions at the quasi-perpendicular bow shock with Cluster CIS [PDF]

Annales Geophysicae, 2001
During the early orbit phase, the Cluster spacecraft have repeatedly crossed the perpendicular Earth’s bow shock and provided the first multi-spacecraft measurements. We have analyzed data from the Cluster Ion Spectrometry experiment (CIS), which

Dual-loop integration framework for model-based system design and reliability analysis using Bayesian networks

Results in Engineering
Integrating model-based systems engineering (MBSE) and reliability analysis is challenging due to the lack of life-cycle reliability consideration in system design, difficulty in tracking design changes in reliability modeling, and limited quantitative ...

Long term and safe relative orbit design for heterogeneous spacecraft clusters

Advances in Space Research, 2021
Abstract The problem of obtaining long term relative orbit configurations for spacecraft clusters with realistic operational considerations such as safety, station keeping and inter-spacecraft distances is addressed. Two different approaches are developed for station keeping and safety objectives. In the first approach, relative orbit configurations,

The Cluster Magnetic Field Investigation: overview of in-flight performance and initial results [PDF]

Annales Geophysicae, 2001
The accurate measurement of the magnetic field along the orbits of the four Cluster spacecraft is a primary objective of the mission. The magnetic field is a key constituent of the plasma in and around the magnetosphere, and it plays an active role

Spacecraft potential control for Double Star [PDF]

Annales Geophysicae, 2005
The spacecraft potential of Double Star TC-1 is positive in large parts of the orbits due to the photo-effect from solar EUV irradiation. These positive potentials typically disturb low energy plasma measurements on board. The potential can be reduced,

Ionic Liquid‐Based Reversible Metal Electrodeposition for Adaptive Radiative Thermoregulation Under Extreme Environments

Advanced Functional Materials, EarlyView.
A wideband tunable electrochromic device with dynamic thermal emissivity control is demonstrated. The system enables adaptive heat regulation via electrochemically modulated silver deposition, achieving efficient cooling and heating states. The flexible design ensures mechanical robustness under bending conditions, making it promising for portable and ...

Spatial scales of the magnetic ramp at the Venusian bow shock [PDF]

Annales Geophysicae, 2011
Typically multi-spacecraft missions are ideally suited to the study of shock spatial scales due to the separation of temporal and spatial variations. These missions are not possible at all locations and therefore in-situ multi-spacecraft measurements ...
