Abstract A common misconception surrounding space exploration is that humanity's pursuit of interplanetary travel, such as missions to Mars, is an escape from Earth. In reality, this endeavour offers an invaluable opportunity to address critical biomedical challenges here at home.

Controls on Solar Wind Entry Identified Through Wind–ACE Heavy‐Ion Diagnostics
Abstract Solar wind (SW) entry into the magnetosphere occurs through several mechanisms, but their dependence on the properties of different ion species is unknown. We compare measurements from Wind‐STICS (magnetosphere) with ACE‐SWICS (L1) to test for any preferential entry between He2+ and SW heavy ions.

Electron Shot Noise on a Current Biased Antenna
Abstract The Parker Solar Probe (PSP) Fields Experiment (FIELDS) uses Radio Frequency Spectrometer (RFS) data and Quasi‐Thermal Noise Spectroscopy (QTN) to determine the temperature and density of electrons in the heliosphere. The FIELDS antennas typically operate with a negative bias current.

Crustal Density Differences Along Mars' Dichotomy Boundary From Gravity and Topography
Abstract Seismic data for Mars has provided constraints on the thickness of its crust, but its density and how much it varies spatially, especially across the hemispherical dichotomy, is still undetermined. We apply a novel constraint in the analysis of spacecraft tracking data to determine Mars' gravity field that allows for the determination of the ...

Locating Moonquakes With Single‐Station Seismology
Abstract Renewed international interest in lunar seismometer deployments requires robust single‐station location approach for the highly scattering Moon's crust. We present an event‐location strategy using major lunar event types recorded by the Apollo seismic network. Frequency‐dependent polarization analysis provides P‐wave back‐azimuth and incidence,
