The Search for Life and Biosignatures on Mars: A Mars System Science Approach (Atmosphere, Hydrosphere, Cryosphere, Lithosphere, Geologic History)
[Astrobiology (Journal)] The most important quest in Mars exploration is the search for biosignatures. We…
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,…

Orbital Biosphere Assays: Lowering Barriers To Big Data
Editor’s note: When we begin to conduct Away Team visits to other worlds that host life we will need to do an assay of how everything on these worlds works together – before visiting. One way to start is from orbit. And prior to that we need to study world from afar via telescopes. Technology…
