DoD focus on climate could shape future investments in weather satellites
Tuesday, 23 February 2021 22:20
WASHINGTON — Defense Secretary Lloyd Austin last month directed the Pentagon to develop plans to prepare for the impact of climate change and extreme weather. The new guidance is intended to shape policies and budgets over the next several years, including investments in satellites for weather monitoring.
Apollo rock samples capture key moments in the Moon's early history, study find
Tuesday, 23 February 2021 21:27
Volcanic rock samples collected during NASA's Apollo missions bear the isotopic signature of key events in the early evolution of the Moon, a new analysis found. Those events include the formation of the Moon's iron core, as well as the crystallization of the lunar magma ocean—the sea of molten rock thought to have covered the Moon for around 100 million years after the it formed.
The analysis, published in the journal Science Advances, used a technique called secondary ion mass spectrometry (SIMS) to study volcanic glasses returned from the Apollo 15 and 17 missions, which are thought to represent some of the most primitive volcanic material on the Moon. The study looked specifically at sulfur isotope composition, which can reveal details about the chemical evolution of lavas from generation, transport and eruption.
"For many years it appeared as though the lunar basaltic rock samples analyzed had a very limited variation in sulfur isotope ratios," said Alberto Saal, a geology professor at Brown University and study co-author. "That would suggest that the interior of the Moon has a basically homogeneous sulfur isotopic composition.
