Investigating the Potential Atmospheric Accumulation and Radiative Impact of the Coming Increase in Satellite Reentry Frequency

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 6, 28 March 2025.
Abstract Construction of numerous satellite megaconstellations in the low Earth orbit (LEO) (300–2,000 km) is projected over the coming decades. Estimates suggest that the number of satellites in an LEO could exceed 60,000 by 2040. The increase in the annual mass flux of anthropogenic material into the upper atmosphere as a result of maintaining these ...

Scaling of the electron dissipation range of solar wind turbulence

, 2013
Electron scale solar wind turbulence has attracted great interest in recent years. Clear evidences have been given from the Cluster data that turbulence is not fully dissipated near the proton scale but continues cascading down to the electron scales ...

Quantifying the Effects of Solar Wind Fluctuations on the Solar Wind‐Magnetosphere Interaction

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract Ala‐Lahti et al. (2024, https://doi.org/10.1029/2024GL112922) present results from a global magnetohydrodynamic simulation of a single geomagnetic substorm for four scenarios: the original solar wind conditions, smoothed low‐frequency solar wind conditions, constant solar wind conditions with a boxcar averaged north/south component of the ...

Analysis of Field-Aligned Currents in the High-Altitude Nightside Auroral Region: Cluster Observation

Journal of Astronomy and Space Sciences, 2019
In this paper we present analysis of current density when the Cluster spacecraft pass the nightside auroral region at about 4-5 RE from the center of Earth. The analysis is made when the inter-spacecraft separation is within 200 km, which allows all four

Fractionated solar power satellite for regional coverage [PDF]

, 2012
This paper presents a preliminary analysis of a fractionated solar power satellite system for regional coverage. The fractionated system is composed of a cluster of satellites, in different possible configurations, that concurrently beam energy to the ...

Significant Plasma Density Depletion From High‐ to Mid‐Latitude Ionosphere During the Super Storm in May 2024

Geophysical Research Letters, Volume 52, Issue 5, 16 March 2025.
Abstract We demonstrate the global response of the ionosphere to the geomagnetic super storm on 10–11 May 2024. The in situ observations from the Swarm spacecraft show a rapid depletion of plasma density in the dawn and dusk sectors following the storm. The in situ data are further complemented by the ground‐based total electron content maps.

Electrostatic Solitary Waves in Earth's Magnetosheath: Properties, Nature, and Origin

Geophysical Research Letters, Volume 52, Issue 5, 16 March 2025.
Abstract We present the analysis of 2,152 electrostatic solitary waves observed aboard the Magnetospheric Multiscale in the Earth's magnetosheath. The electric field of the solitary waves is predominantly bipolar and parallel to the local magnetic field.
