These maps show the infall of particles (protons, top two rows, and electrons, bottom two rows) across the surface of Mercury. The infall of particles is dependent on the orientation of the interplanetary magnetic field (IMF) on which the protons and electrons in the solar wind travel. The first rows are for a northward pointing IMF and the second rows are for a southward pointing IMF, as shown in the image with the Sun on the left. Each column is for a different energy level of the particles, labeled over the first-row image. Credit: Federico Lavorenti (2023).

Mapping the Sun’s Interaction with Mercury’s Surface

by SpaceRef EditorSeptember 12, 2023July 15, 2024

A new study maps the infall of protons and electrons from the solar wind to geographical location on the surface of Mercury, giving scientists new insight into how interactions with […]

Two areas in the Mare Ingenii swirl region examined by the PSI team. The crater at the center of the topmost image is at 162 longitude, -35 latitude. Images were extracted from the Lunar Reconnaissance Orbiter Camera (LROC) quickmap (https://quickmap.lroc.asu.edu) provided by Arizona State University.

PSI Study Shows Evidence of Highly Mobile Lunar Regolith

by SpaceRef EditorAugust 31, 2023July 15, 2024
Latitudinally corrected 3-GHz TA shown at midnight local time. (a) These data show a clear localized antenna temperature (TA) enhancement of about 9 degrees Kelvin centered on the mapped Compton–Belkovich topographic feature. This feature is not explainable by topography, surface rock distribution or material properties and is seen at all frequencies and times of day. (b,c) The context globe shows Lunar Prospector-measured thorium scaled 0–35-ppm Th (b) and the perspective view shows the TA superimposed on the central surface feature resembling a volcanic system topography (c).
