A somewhat personalized overview is presented of the effects of solar-terrestrial processes on electrical technologies, beginning with the electrical telegraphs in the mideighteenth century to the current era of extensive ground-and space-based commercial and governmental technical systems (including national security) upon which modern society depends. As human technologies increased in diversity over the last century and a half, space weather effects have continued to be of significant importance in the successful design and operations of many of these technologies.

“…The interaction of near-Earth bodies, ranging from Low Earth Orbit (LEO) to Geosynchronous Earth Orbit (GEO), with the space environment leads to many technical and scientific challenges (see reviews [26,29]). The LEO space environment (100 − 2000km altitude) can be described as a cold, partially ionised, high-density plasma when compared to the fully ionised plasma found in GEO.…”

“…Brundin [14]'s conclusions were based on the assertion that LEO spacecraft surface potentials never became more negative than −0.75 V, a statement supported by major works of the era [ 25,56,57]. The growing sophistication of spacecraft, particularly in LEO, has lead to an increased interest in the interaction of highly charged space platforms with the LEO environment [26,29] (see [53,54] for example).…”

“…Recent reviews of spacecraft charging in LEO [26,29] recognise spacecraft surface potentials may achieve significant voltages relative to the surrounding environment both naturally and artificially. Anderson [3] presented a statistical study of 1600 charging events (defined as spacecraft charges exceeding −100 V) on the DMSP spacecraft at 840 km during auroral crossings.…”

pdFOAM: A PIC-DSMC code for near-Earth plasma-body interactions

et al. 2017

Understanding the interaction of the near-Earth space environment with orbiting bodies is critical, both from a design and scientific perspective. In Low Earth Orbit (LEO), the interaction between the ionosphere and orbiting objects is well studied from a charging perspective. Not well understood is the effect of the ionosphere on the motion of LEO objects i.e. charged aerodynamics. This paper presents the implementation, validation, and verification of the hybrid electrostatic Particle-in-Cell (PIC) -Direct Simulation Monte Carlo (DSMC) code, pdFOAM, to study both the neutral and charged particle aerodynamics of LEO objects. The 2D aerodynamic interaction of a cylinder with a fixed uniform surface potential of −50 V and mesothermal O + and H + plasmas representative of ionospheric conditions is investigated. New insights into the role of bounded ion jets and their effect on surface forces are presented. O + bounded ion jets are observed to cause a 4.4% increase ion direct Charged Particle Drag (dCPD), while H + ion jets produce a net reduction in H + drag by 23.7% i.e. they cause a thrust force. As a result, we conclude that past work, primarily based on Orbital Motion Limited theory, does not adequately capture the physics of LEO charged aerodynamics. Hence, we recommend a revisit of conclusions regarding the significance of CPD to LEO objects -pdFOAM being an appropriate tool for this purpose.

“…Space weather has severe impacts on satellites (Tribble 1995;Hastings and Garrett 1996), rocket launchers (Boscher et al 1998;Bourdarie and Bourrieau 1999) and GPS/navigation systems (Goodman and Aarons 1990;Wellenhof et al 2001). Radiation effects depend on the energy of the radiation, from galactic cosmic rays, solar energetic particles and radiation trapped in the Earth's Van Allen belts (Bourrieau et al 1996;Crosby et al 2006).…”

Space Weather: Physics, Effects and Predictability

The time varying conditions in the near-Earth space environment that may affect space-borne or ground-based technological systems and may endanger human health or life are referred to as space weather. Space weather effects arise from the dynamic and highly variable conditions in the geospace environment starting from explosive events on the Sun (solar flares), Coronal Mass Ejections near the Sun in the interplanetary medium, and various energetic effects in the magnetosphere-ionosphere-atmosphere system. As the utilization of space has become part of our everyday lives, and as our lives have become increasingly dependent on technological systems vulnerable to the space weather influences, the understanding and prediction of hazards posed by these active solar events have grown in importance. In this paper, we review the processes of the Sun-Earth interactions, the dynamic conditions within the magnetosphere, and the predictability of space weather effects on radio waves, satellites and ground-based technological systems today.
