Report

Evidence for geologically recent explosive volcanism in Elysium Planitia, Mars

Autor: Horvath, David G., Moitra, Pranabendu, Hamilton, Christopher W., Craddock, Robert A., Andrews-Hanna, Jeffrey C.

Volcanic activity on Mars peaked during the Noachian and Hesperian periods but has continued since then in isolated locales. Elysium Planitia hosts numerous young, fissure-fed flood lavas with ages ranging from approximately 500 to 2.5 million years

Climate simulations of early Mars with estimated precipitation, runoff, and erosion rates

Autor: Ramirez, Ramses M., Craddock, Robert A., Usui, Tomohiro

Publikováno v: Journal of Geophysical Research: Planets, 125, e2019JE006160 (2020)

The debate over the early Martian climate is among the most intriguing in planetary science. Although the geologic evidence generally supports a warmer and wetter climate, climate models have had difficulty simulating such a scenario, leading some to

The geological and climatological case for a warmer and wetter early Mars

Autor: Ramirez, Ramses M., Craddock, Robert A.

Publikováno v: Ramirez, R.M. and Craddock, R.A. 2018. The geological and climatological case for a warmer and wetter early Mars. Nature Geoscience 11, 230 - 237

The climate of early Mars remains a topic of intense debate. Ancient terrains preserve landscapes consistent with stream channels, lake basins, and possibly even oceans, and thus the presence of liquid water flowing on the Martian surface 4 billion y
