LPI Webinar
C.B. had a great time presenting her group’s research about Mars to the LPI via Webinar. Her talk was titled “Seismological Constraints on Mars Interior Structure: Results from the InSight Mission”

Seismic detection of a deep mantle discontinuity within Mars by InSight
The paper “Seismic detection of a deep mantle discontinuity within Mars by InSight” led by Quancheng Huang is out! Summary: The depth and sharpness of a midmantle seismic discontinuity, associated with the phase transition from mineral olivine to its higher-pressure polymorphs, provide essential clues to understanding the temperature and composition of Martian mantle. Using data …
