Mars's core, widely thought to be at least partially molten, may eventually solidify completely, and researchers have turned to lab experiments to find out how.
Harriet Lau and Joseph O'Rourke will receive the 2016 Study of the Earth's Deep Interior Focus Group Graduate Research Award at the 2016 American Geophysical Union Fall Meeting, to be held 12–16 December in San Francisco, Calif. This award is given annually for advances that contribute to the understanding of the deep interior of the Earth or other planetary bodies using a broad range of observational, experimental, and/or theoretical approaches.
NASA has set a new 2018 launch date for a spacecraft to probe the Red Planet's interior, after instrument failure hobbled preparations for the mission.
The mission will spend 20 months collecting data on the planet's core, its magnetic field, and the composition of its atmosphere.
Scientists explore how interactions between a rocky planet's climate, mantle, and core can affect its evolution and determine whether it could sustain life.
The experiments mimicked cooling of magma at the lunar surface. They found that any water in interior molten rock might have escaped so fast at the surface that none was left to be measured.
Rebecca Fischer and Zack Geballe have been awarded the 2014 Mineral and Rock Physics Graduate Research Award. This award is given to one or more promising young scientists in recognition of outstanding contributions achieved during their Ph.D. research.
Workshop on Volatiles in the Martian Interior; Houston, Texas, 3–4 November 2014
Laser-driven experiments on silica help scientists learn more about planetary formation and evolution.
