A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

Machine Learning the Dark Matter Halo Mass of Milky Way-Like Systems

The Open Journal of Astrophysics
Despite the Milky Way's proximity to us, our knowledge of its dark matter halo is fairly limited, and there is still considerable uncertainty in its halo mass.

Oxychlorine Species on Mars: A Review

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

HaloFlow. I. Neural Inference of Halo Mass from Galaxy Photometry and Morphology

The Astrophysical Journal
We present HaloFlow , a new machine-learning approach for inferring the mass of host dark matter halos, M _h , from the photometry and morphology of galaxies ( https://github.com/changhoonhahn/haloflow/ ).

Correlation Patterns of Muon Flux With Vertical Atmospheric Profiles: Insights From Monte Carlo Simulations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract The production, attenuation, and absorption of secondary cosmic rays (SCR) are influenced by atmospheric parameters such as air pressure and temperature. To reliably correlate SCR flux measurements with atmospheric ionization driven by energetic particle precipitation, these dependencies must be quantified.

ON THE FORMATION OF THE DISK OF SATELLITES OF THE MILKY WAY: SIMULATION OF THE COLLISION OF TWO GALAXIES

Momento, 2014
At present there is some evidence showing that the satellite galaxies of the Milky Way might be distributed on a disc structure, known as the disc of satellites.

Study of Satellite Plane Structure Characteristics Based on TNG50 Simulations: A Comparative Analysis from Plane to Nonplane Structures

The Astrophysical Journal
In recent years, multiple plane structures of satellite galaxies have been identified in the nearby Universe, although their formation mechanisms remain unclear.
