No Degree, No Lab, No Borders: An Independent Researcher's Journey From Yemen to Global Science

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract I grew up in Yemen with a dream to study space, but my country had no astronomy programs, no universities for astrophysics, and soon, no stable peace. This Perspective is a personal and systemic account of how I pursued planetary science from a conflict zone—with no smartphone, no home internet, no supervisor, and no institutional backing.

Charge Exchange in Laboratory and Astrophysical Plasmas

open access: yesInternational Astronomical Union Colloquium, 1988
AbstractRecent experiments in tokamak plasmas demonstrate that charge exchanges manifest themselves in a wide variety of situations. It is now realized that charge exchanges involving excited states of hydrogen should be considered: these reactions represent a challenge for atomic physics, detailed plasma modeling, and quantitative plasma diagnostics ...

The Benefits of High Resolution Multispectral TIR Data and Its Impending Loss by NASA After Four Decades

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract NASA has led multispectral (≥3 wavelength bands) thermal infrared (TIR) sensor development from the earliest days of the agency. These data are critical in addressing a wide range of scientific questions and administration priories by measuring both temperature (for wildfire and volcanic eruption monitoring, agricultural plant stress, and ...

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

open access: yesX-Ray Spectrometry, Volume 55, Issue 5, Page 721-729, September/October 2026.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244 Cm sources, and come with severe concerns on radiation safety and isotope availability.

Collisionless Shocks: Contemporary State After Three Quarters of a Century of Research

open access: yesReviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract The collisionless shock research started in the late 1950s. Since then, plenty of data have been accumulated due to the large number of missions in the heliosphere, providing in situ measurements of the fields and particles. The quality of these measurements has vastly improved, especially in the last two decades.

Statistical Study of Betatron and Fermi Electron Acceleration at Dipolarization Fronts

open access: yesGeophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Magnetic reconnection jets in Earth's magnetotail are regions of electron heating and acceleration. They are often associated with dipolarization fronts (DFs), which are characterized by sharp increases in the northward magnetic field component Bz ${B}_{z}$.
