Degassing of CO2 triggers large-scale loss of helium from magma oceans

Communications Earth & Environment
The moon-forming impact caused widespread melting and vaporization of the proto-Earth, leading to the formation of a protolunar disk1,2. Volatile elements trapped in the inner parts of the disk condensed together with heavier elements into a global magma

Green Revenue Generation and Sales Contribution: Are Consumers Willing to Bear the Cost of Sustainability?

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines the strategic implications of environmental activities on firm performance, specifically focusing on contribution per dollar sale and operational cost efficiency within US companies. Using a comprehensive dataset of 17,735 firm‐year observations from 2008 to 2023, we find that firms engaging in green revenue generation do ...

Prolonged Multi‐Phase Magmatism Due To Plume‐Lithosphere Interaction as Applied to the High Arctic Large Igneous Province

Geochemistry, Geophysics, Geosystems
The widespread High Arctic Large Igneous Province (HALIP) exhibits prolonged melting over more than 50 Myr, an observation that is difficult to reconcile with the classic view that large igneous provinces (LIPs) originate from melting in plume heads ...

High-resolution simulations of the final assembly of Earth-like planets. 2. Water delivery and planetary habitability. [PDF]

Astrobiology, 2005
The water content and habitability of terrestrial planets are determined during their final assembly, from perhaps 100 1,000-km "planetary embryos " and a swarm of billions of 1-10-km "planetesimals.

Terrestrial Lithium Exploration Adapted From Raman Diagnosis of Phyllosilicates for Mars

Journal of Raman Spectroscopy, EarlyView.
Analyses using a benchtop Raman instrument at the University of Aberdeen and a prototype instrument for remote deployment on Mars based at the University of Leicester successfully discriminated between four varieties of mica (possibly lithium‐rich rocks).

Maximizing Scientific Exploitation of Raman Spectroscopy With A.C.M.E. (Atmospheric Chamber for Measurements in Environment)

Journal of Raman Spectroscopy, EarlyView.
Simulated planetary gas detection using the A.C.M.E. chamber and a novel hollow‐core fiber Raman sensor. Controlled atmospheric mixtures were used to evaluate the sensor’s performance, demonstrating its capability to detect gases such as CO₂, O₂, and N₂. The results support the applicability of the HCF‐based Raman sensor in future planetary exploration

A Novel Metric for Assessing Climatological Surface Habitability

The Planetary Science Journal
Planetary surface habitability has so far been considered, in the main, on a global scale. The increasing number of 3D modelling studies of (exo)planetary climate has highlighted the need for a more nuanced understanding of surface habitability.

Reactivity of Cyanide at Water-Ice Interfaces: Implications for the Search for Organics on Icy Worlds

Frontiers in Astronomy and Space Sciences, 2020
Icy moons in our solar system are targets of interest to search for signs of life and habitability beyond Earth. They are the astrobiological aim for several developing space missions (JUICE, Europa Clipper, and Europa Lander). A further understanding of

Advances and Trends in Terrain Classification Methods for Off‐Road Perception

Journal of Field Robotics, EarlyView.
ABSTRACT Off‐road autonomous vehicles (OAVs) are becoming increasingly popular for navigating challenging environments in agriculture, military, and exploration applications. These vehicles face unique challenges, such as unpredictable terrain, dynamic obstacles, and varying environmental conditions.
