Session Introduction

2:20 PM

Plesa A.-C.* Wieczorek M. Knapmeyer M. Rivoldini A. Bozdag E. et al.

InSight's Constraints on the Interior of Mars: Geodynamical Models and Observations [#2212]
In this contribution we discuss how InSight’s new data can be used together with geodynamical mantle convection models to constrain the thermal history of Mars.

2:30 PM

Kiefer W. S.* Weller M. B. Duncan M. S. Filiberto J.

Mantle Plume Magmatism in Elysium Planitia as Constrained by InSight Seismic Observations [#2341]
An upwelling mantle plume in Cerberus Fossae explains the young volcanism and is consistent with InSight seismic velocities. The mantle must be quite dry.

2:40 PM

Samuel H.* Drilleau M. Rivoldini A. Xu Z. Huang Q. et al.

Evidence for Mars Deep Mantle Layering in the Light of InSight Seismic Data [#1482]
We show the evidence for the presence of deep martian mantle layering with InSight seismic and geodetic data along with other observational constraints.

2:50 PM

Khan A.* Huang D. Duran C. Sossi P. Murakami M. et al.

Evidence for a Martian D"-Like Layer [#1448]
We report on the presence of a molten silicate lower-mantle layer overlying a dense and smaller liquid Fe-Ni alloy core using seismic observations from InSight.

Panel Q&A

3:20 PM

Horleston A. C.* Clinton J. F. Ceylan S. Kawamura T. Stähler S. C. et al.

Finding Marsquakes: InSight's Marsquake Service and the Mars Seismic Catalogue [#1940]
An overview of the Marsquake Service operations and the seismic catalogue from >4 years of InSight SEIS data.

3:30 PM

Giardini D.* Ceylan S. Stähler S. C. Clinton J. F. Kim D. et al.

Review of the Seismicity on Mars as Recorded by InSight [#1213]
We present the current understanding of martian seismicity and the different event types based on InSight’s seismic data and Marsquake Service event catalog.

3:40 PM

Daubar I. J.* Fernando B. Garcia R. F. Collins G. S. Golombek M. P. et al.

Martian Seismic Events Confirmed as Impacts to Date [#2616]

Wojcicka N.* Zenhausern G. Collins G. S. Stahler S. C. Daubar I. J. et al.

Impact Rate on Mars Implied by Seismic Observations [#2286]
What marsquakes tell us / about the cratering rate / on surface of Mars.

Panel Q&A

4:20 PM

Kim D.* Stähler S. C. Boehm C. Lekic V. Giardini D. et al.

Obtaining Average Crustal and Uppermost Mantle Properties for Planetary Models of Mars [#1943]
Higher-orbit Rayleigh waves constrain average crustal and uppermost mantle properties that better represent global variations of the martian interior structure.

4:30 PM

Beghein C.* Li J. Weidner E. Maguire R. Wookey J. et al.

Lithological Interpretation of Martian Crustal Seismic Velocities from InSight [#2138]
We compare seismic velocities of different layers and at various locations on Mars to rock physics models in terms of lithology, porosity, and fluid/ice content.

4:50 PM

Gyalay S.* Nimmo F. Plesa A.-C. Wieczorek M. A. Citron R. et al.

The Rise and Fall of Crustal Porosity: Insight on Early Martian History [#2938]
