The Chemical Inheritance of Icy Moons
AbstractLarge icy exomoons may represent a ubiquitous habitable environment yet remain on the fringes of detectability.   Despite decades of progress in theoretical work, the nature and origin of the solids which form the building blocks of  satellites remains a topic of debate. We utilize a radiation-thermochemical disk modeling code

DNA Polymerization in Icy Moon Abyssal Pressure Conditions
AstrobiologyEvidence of stable liquid water oceans beneath the ice crust of moons within the Solar System is of great interest for astrobiology. In particular, subglacial oceans may present hydrothermal processes in their abysses, similarly to terrestrial hydrothermal vents.

Global Policy, EarlyView.ABSTRACT The European Union's proposed Space Law aims to establish a unified approach for sustainable space activities across the EU. While the EU's satellite constellations contribute to sustainability efforts, they can also have negative environmental impacts.

The Planetary Science JournalUnderstanding the interior structures of icy moons is pivotal for addressing their origins and habitability. We introduce an approach employing the gravity field spectrum as an additional constraint for the inversion of differentiated icy bodies ...

Production of Oxidants by Ion Bombardment of Icy Moons in the Outer Solar System
Advances in Astronomy, 2011 Our groups in Brazil, France and Italy have been active, among others in the world, in performing experiments on physical-chemical effects induced by fast ions colliding with solids (frozen gases, carbonaceous and organic materials, silicates, etc.) of ...

Lady Anne Kerr: From the Rise of International Conference Interpreting to the Whitlam Dismissal
Australian Journal of Politics &History, EarlyView.Before Anne Robson (née Taggart) became the second Lady Kerr upon marrying governor‐general John Kerr in 1975, she had an international career of some 30 years working as a French to English interpreter and consultant at over 30 national and international conferences and became the first Australian elected to the International Association of Conference

Measuring Ganymede’s Librations with Laser Altimetry
Geosciences, 2019 Jupiter’s moon Ganymede might be in possession of a subsurface ocean located between two ice layers. However, from Galileo data it is not possible to unambiguously infer the thickness and densities of the individual layers.

Bioethics, EarlyView.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
Bioethics, EarlyView.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 ...
