Earth As A Potential Source Of Llife For Europa’s Subsurface Ocean
The paper discusses the possibility of dust particles containing living bacteria ejected from Earth reaching Europa and landing on its surface. It is shown that, taking certain factors into account, over a period of 30 − 80 Myr (the estimated age of Europa’s ocean), Jupiter’s moon would have been impacted…
Keep readingDust To Dust: Prospects For Passive Technosignatures As Relics Of ETI
Technological societies are separated in time, not just space — that is the lesson of the Drake equation. Might the best way to seek them be to find technosignatures that persist long after their creators? I present work I and my collaborators have done on the idea of passive technosignatures,…

Turbulence-coupled Electrodynamics Of The Martian Year 34 Global Dust Storm On Mar
We studied the electrodynamic environment during the Martian year 34 (MY 34) global dust storm using data from the Mars Climate Database v.6.1. Our physics-based approach looked at triboelectric charging, atmospheric conductivity, and electrostatic breakdown using the Paschen criterion. We aimed to find out when and where the lower atmosphere could support electric fields strong…
