Characterizing ICME-related Forbush Decreases at Mercury using MESSENGER Observations: Identification of a One or Two-Step Structure

Emma E. Davies, Réka M. Winslow, David J. Lawrence

The large-scale magnetic structure of interplanetary coronal mass ejections (ICMEs) has been shown to cause decreases in the galactic cosmic ray (GCR) flux measured in situ by spac…

Space-based Measurements of Neutron Lifetime: Approaches to Resolving the Neutron Lifetime Anomaly

David J. Lawrence, Jack T. Wilson, Patrick N. Peplowski

Free neutrons have a measured lifetime of 880 s, but disagreement between existing laboratory measurements of ~10 s have persisted over many years. This uncertainty has implication…

Measurement of the Free Neutron Lifetime using the Neutron Spectrometer on NASA's Lunar Prospector Mission

Jack T. Wilson, David J. Lawrence, Patrick N. Peplowski +2

We use data from the Lunar Prospector Neutron Spectrometer to make the second space-based measurement of the free neutron lifetime finding $τ_n=887 \pm 14_\text{stat}{\:^{+7}_{-3\:…

Space-Based Measurement of the Neutron Lifetime using Data from the Neutron Spectrometer on NASA's MESSENGER Mission

Jack T. Wilson, David J. Lawrence, Patrick N. Peplowski +2

We establish the feasibility of measuring the neutron lifetime via an alternative, space-based class of methods, which use neutrons generated by galactic cosmic ray spallation of p…

Chemically-distinct regions within Venus' atmosphere revealed by MESSENGER-measured N2 concentrations

Patrick N. Peplowski, David J. Lawrence, Jack T. Wilson

A defining characteristic of the planet Venus is its thick, CO2-dominated atmosphere. Despite over fifty years of robotic exploration, including thirteen successful atmosphere prob…

Ex Luna, Scientia: The Lunar Occultation eXplorer (LOX)

R. S. Miller, M. Ajello, J. F. Beacom +16

LOX is a lunar-orbiting astrophysics mission that will probe the cosmos at MeV energies. It is guided by open questions regarding thermonuclear, or Type-Ia, supernovae (SNeIa) and…
