A passive de-orbiting strategy for high altitude CubeSat missions using a deployable reflective balloon

open access: yes, 2011
A de-orbiting strategy for small satellites, in particular CubeSats, is proposed which exploits the effect of solar radiation pressure to increase the spacecraft orbit eccentricity so that the perigee falls below an altitude where atmospheric drag will ...

ALERA‐V Version 1.0: An Objective Analysis Dataset of the Venus Atmosphere

open access: yesGeoscience Data Journal, Volume 13, Issue 3, July 2026.
Using observations from the Venus orbiter Akatsuki, we present the first objective analysis dataset of the Venus atmosphere. ALERA‐V, generated with the ALEDAS‐V system using the LETKF, is expected to support studies of atmospheric dynamics and the planning of future satellite missions.

A Statistical Study of Warm Plasma Cloak Particles Using Van Allen Probe Data

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The Warm Plasma Cloak (WPC) consists of ions in the inner magnetosphere with energies between 10 eV and 1 keV and showing a bidirectional pitch angle distribution of particles. These particles play an important role in wave–particle interactions and in controlling the dayside reconnection rate at the magnetopause.

What Is Space Bioethics?

open access: yesBioethics, Volume 40, Issue 6, Page 558-564, July 2026.
ABSTRACT Classical bioethics examines moral issues in terrestrial medicine and the life sciences. According to Konrad Szocik, space bioethics merely relocates those questions to harsher environments. We argue that this view is incomplete: space bioethics is a genuinely original domain.

Out There No One Has a Right to Die

open access: yesBioethics, Volume 40, Issue 6, Page 565-572, July 2026.
ABSTRACT The eventual goal of space exploration is to colonize exoplanets and their moons outside our solar system. This is a dangerous and immoral endeavour. The extraterrestrial life forms encountered would be hostile, vulnerable or both, and the descendants of the original pioneers would be involuntarily exposed to hazardous conditions and ...
