Scaling laws for the energy transfer in space plasma turbulence

Raffaele Marino et al.

Summary: One characteristic trait of space plasmas is the multi-scale dynamics resulting from non-linear transfers and conversions of various forms of energy. Turbulence is a major cross-scale energy transfer mechanism in space plasmas, affecting the energy fate at intermediate scales. Other mechanisms, such as magnetic reconnection and particle energization, also contribute to the challenging prediction of the dynamical state of space plasmas. In recent decades, scaling laws and advanced methodologies have played a crucial role in characterizing the energy transfer in space plasmas, together with robotic missions.

Strategies for Determining the Cascade Rate in MHD Turbulence: Isotropy, Anisotropy, and Spacecraft Sampling

Yanwen Wang et al.

Summary: This article investigates the accurate evaluation of cascade rates in various systems, taking into account the limitations of available data and turbulence symmetry. By examining the increment form of the von Karman-Howarth equation, the accuracy and feasibility of third-order laws are effectively assessed. The conditions for obtaining correct and accurate dissipation rates from these laws are studied using simulation results.

MagneToRE: Mapping the 3-D Magnetic Structure of the Solar Wind Using a Large Constellation of Nanosatellites

Bennett A. Maruca et al.

Summary: Current spacecraft can measure particles and fields of the solar wind, but cannot fully determine its 3-D structure. The concept of the Magnetic Topology Reconstruction Explorer (MagneToRE) proposes a large constellation of in-situ spacecraft to reconstruct 3-D maps of the solar wind's dynamic magnetic structure for the first time.
