The first billion years on Earth and Mars: A geologist’s perspective – Clark M. Johnson

Clark M. Johnson

Despite the likelihood of early habitability on both Earth and Mars, the geologic evolution of these two planets, and the rock record they preserve, is quite different. Plate tectonics on Earth played a central role in evolution of our biosphere, and yet has destroyed much of the early Earth rock record, creating great challenges for finding evidence for early life on Earth. Mars did not have Earth-style plate tectonics, but the evidence is clear that Mars was habitable very early in its history. Preservation of the early Mars geologic record is excellent, raising the possibility that it might contain evidence for the earliest life in the Solar System...

Observing Our Solar System – Martin Mika

Observing Our Solar System

The talk will outline the basics of our solar system: history, characteristics of the planets, how they move, and how to observe them with amateur telescopes. I will then also discuss some imaging techniques and touch on citizen science projects that can be undertaken by amateurs, with a few examples from some of the top planetary imagers around the world.

About the Speaker:
Martin Mika is a long time observer and astrophotographer and is the Observatory Director for the MAS.
