Venus' Mesosphere Shows Sharp Rise in Deuterium to Hydrogen Ratio
Tokyo, Japan (SPX) Aug 21, 2024
Researchers using the Solar Occultation in the Infrared (SOIR) instrument aboard the European Space Agency's Venus Express probe have observed a significant and unexpected increase in the deuterium to hydrogen ratio (HDO/H2O) in Venus' mesosphere. This discovery adds a new layer of complexity to our understanding of Venus' water history, raising questions about whether the planet may have once h
