Jack William Conrad

NPP Fellow at NASA Marshall Space Flight Center

Welcome! I'm currently a Postdoctoral researcher at NASA Marshall, primarily working with Caleb Fassett.

My research interest focus on determining the internal large-scale history and properties of worlds by their external expression (topography, gravity, morphology, etc.).

Francis Nimmo was my primary advisor in graduate school. Find PDFs of our published works on his website! For newer (or any) papers feel free to email me for copies.

Major Research Topics:

Pluto and Charon Tectonics

Are Pluto and Charon representative of Kuiper Belt Objects in terms of their tectonic evolution?

Global Scale Topography

Using spherical harmonics and terrain evolution models unveils how topography is the result of interlinked processes.

Lunar Gravity Anomalies

The condition of lunar gravity anomalies relative to topography are one of the best ways to constrain the Moon's thermal history.

Venusian Canali

Channels on the surface of Venus likely formed during transition to its modern climate, but we need to understand them better to be sure.

Lunar Sinuous Rilles

Did these long channels on the lunar surface form by flowing erosion or collapsed lava tubes?

Secondary Cratering

Craters formed from ejecta reveal crustal property changes across geologic boundaries.
