Abstract Launched on 12 Aug. 2018, NASA's Parker Solar Probe had completed 13 of its
scheduled 24 orbits around the Sun by Nov. 2022. The mission's primary science goal is to …

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 …

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 …

A major challenge for gravitational-wave (GW) detection in the μ Hz band is engineering a
test mass (TM) with sufficiently low acceleration noise. We propose a GW detection concept …

One of the most important early results from the Parker Solar Probe (PSP) is the ubiquitous
presence of magnetic switchbacks, whose origin is under debate. Using a three-dimensional …

The Solar Orbiter mission seeks to make connections between the physical processes
occurring at the Sun or in the solar corona and the nature of the solar wind created by those …

The Wind spacecraft, launched on November 1, 1994, is a critical element in NASA's
Heliophysics System Observatory (HSO)—a fleet of spacecraft created to understand the …

The Sun, as an active star, is the driver of energetic phenomena that structure interplanetary
space and affect planetary atmospheres. The effects of Space Weather on Earth and the …

The electrons are an essential particle species in the solar wind. They often exhibit non-
equilibrium features in their velocity distribution function. These include temperature …

Structures in the solar wind result from two basic mechanisms: structures injected or
imposed directly by the Sun, and structures formed through processing en route as the solar …
