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,

On the Conditions of Aliasing Effects in Constellations with More than Four Spacecraft [PDF]

arXiv, 2020
The k-filtering/wave telescope method has been successfully applied to the four-spacecraft measurements from Cluster II and MMS, revealing the four-dimensional power spectral density $\textrm{PSD}(\omega, \mathbf k)$. As the number of spacecraft within a constellation increases, the geometry becomes more complicated, and it is harder to find the first ...

Facing the Risk of Greenwashing in the ESG Report of Global Companies: The Importance of Life Cycle Thinking

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Accurate reporting on the sustainability of business value propositions must be supported by reliable data sources and sound methodologies such as life cycle assessment (LCA). Showing commitment to more responsible activity without quantifying business impacts, or quantifying them only partially, could fall into greenwashing practices.

A global study of hot flow anomalies using Cluster multi-spacecraft measurements [PDF]

Facsko, G., Nemeth, Z., Erdos, G., Kis, A., and Dandouras, I.: A global study of hot flow anomalies using Cluster multi-spacecraft measurements, Ann. Geophys., 27, 2057-2076, https://doi.org/10.5194/angeo-27-2057-2009, 2009, 2018
Hot flow anomalies (HFAs) are studied using observations of the magnetometer and the plasma instrument aboard the four Cluster spacecraft. We study several specific features of tangential discontinuities on the basis of Cluster measurements from the time periods of February-April 2003, December 2005-April 2006 and January-April 2007, when the ...

Microbiologically influenced corrosion in aluminium alloys and premier techniques for comprehensive identification and characterization across diverse metal types

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Microbiologically influenced corrosion (MIC) is acknowledged as a significant type of corrosion due to its extensive impact on metal/alloy surfaces. As MIC accounts for 20% of all corrosion instances, it is a critical factor causing service failure of engineering materials such as steel and aluminium alloy.

First Cluster results of the magnetic field structure of the mid- and high-altitude cusps [PDF]

Annales Geophysicae, 2001
Magnetic field measurements from the four Cluster spacecraft from the mid- and high-altitude cusp are presented. Cluster underwent two encounters with the mid-altitude cusp during its commissioning phase (24 August 2000). Evidence for field-aligned
