Evolution of lunar wake potentials: structure, energy conversion, and their imprints on velocity distributions
Xin An, Vassilis Angelopoulos, Jasper S. Halekas +4
We study the evolution of electric potentials in the lunar wake. The wake potential exhibits two distinct spatial scales. The macroscopic scale arises from solar wind expansion int…
Simultaneous Mars-orbit observations reveal Kelvin-Helmholtz instability-driven bulk atmospheric ion escape
Chi Zhang, Chuanfei Dong, Gangkai Poh +11
Atmospheric ion escape driven by the solar wind is a key process controlling the long-term loss of the Martian atmosphere. Localized plasma clouds can carry substantial fluxes of p…
Simultaneous TRACERS and THEMIS Observations of Reversed Cusp Ion Dispersions and Dual-Lobe Reconnection
M. Ãieroset, S. A. Fuselier, J. B. Bonnell +20
We present observations from two consecutive TRACERS-2 orbits through the northern low-altitude cusp. During the first crossing, TRACERS-2 observed reversed cusp ion dispersion and…
Storm-Time Cusp Precipitation: Insights from TRACERS Multi-Crossing Observations
Shirsh Lata Soni, David M. Miles, Jasper Halekas +12
The dayside cusp provides a direct pathway for solar wind plasma entry into the magnetosphere ionosphere system through magnetic reconnection. Using low altitude ion and electron m…
Inferring lunar wake potentials from electron phase space densities
Xin An, Shaosui Xu, Vassilis Angelopoulos +4
Inferring electric potentials from electron phase space density measurements in the lunar wake is complicated by two challenges: the asymmetry between the sunward and anti-sunward…
Solar Wind Classifications at Mars using Machine Learning Techniques
Catherine E. Regan, Silvia Ferro, Austin M. Smith +5
Understanding solar wind variability throughout the heliosphere is essential for fundamental space physics and future exploration of the Moon and Mars. The Mars Atmosphere and Vola…
