A UK perspective on tackling the geoscience racial diversity crisis in the Global North
Nature Geoscience Springer Nature 14:5 (2021) 256-259
Abstract:
Geoscientists will play key roles in the grand challenges of the twenty-first century, but this requires our field to address its past when it comes to diversity and inclusion. Considering the bleak picture of racial diversity in the UK, we put forward steps institutions can take to break down barriers and make the geosciences equitable.Evidence for disequilibrium chemistry from vertical mixing in hot Jupiter atmospheres: A comprehensive survey of transiting close-in gas giant exoplanets with warm-Spitzer/IRAC

Upper limits for phosphine (PH3) in the atmosphere of Mars
Astronomy and Astrophysics EDP Sciences 649:May 2021 (2021) L1
Abstract:
Phosphine (PH3) is proposed to be a possible biomarker in planetary atmospheres and has been claimed to have been observed in the atmosphere of Venus, sparking interest in the habitability of Venus’s atmosphere. Observations of another biomarker, methane (CH4), have been reported several times in the atmosphere of Mars, hinting at the possibility of a past or present biosphere. The Atmospheric Chemistry Suite on the ExoMars Trace Gas Orbiter has a spectral range that includes several absorption lines of PH3 with line strengths comparable to previously observed CH4 lines. The signature of PH3 was not observed in the 192 observations made over a full Martian year of observations, and here we report upper limits of 0.1–0.6 ppbv.Lucy Mission to the Trojan Asteroids: Instrumentation and Encounter Concept of Operations
