One characteristic trait of space plasmas is the multi-scale dynamics resulting from non-
linear transfers and conversions of various forms of energy. Routinely evidenced in a range …

A detailed overview of the knowledge gaps in our understanding of the heliospheric
interaction with the largely unexplored Very Local Interstellar Medium (VLISM) are provided …

Aims. Solar Orbiter, the first mission of ESA's Cosmic Vision 2015–2025 programme and a
mission of international collaboration between ESA and NASA, will explore the Sun and …

After decades of observations of solar energetic particles from space-based observatories,
relevant questions on particle injection, transport, and acceleration remain open. To address …

During the thirteenth encounter of the Parker Solar Probe (PSP) mission, the spacecraft
traveled through a topologically complex interplanetary coronal mass ejection (ICME) …

After leaving the Sun's corona, the solar wind continues to accelerate and cools, but more
slowly than expected for a freely expanding adiabatic gas. Alfvén waves are perturbations of …

Context. The Extreme Ultraviolet Imager (EUI) is part of the remote sensing instrument
package of the ESA/NASA Solar Orbiter mission that will explore the inner heliosphere and …

The first radial alignment between Parker Solar Probe and Solar Orbiter spacecraft is used
to investigate the evolution of solar wind turbulence in the inner heliosphere. Assuming …

A primary goal of the Parker Solar Probe (PSP) Mission is to answer the outstanding
question of how the solar corona plasma is heated to the high temperatures needed for the …

Aims. The Spectral Imaging of the Coronal Environment (SPICE) instrument is a high-
resolution imaging spectrometer operating at extreme ultraviolet wavelengths. In this paper …
