Carbonate minerals have been detected in Jezero crater, an ancient lake basin that is the landing site of the Mars 2020 Perseverance rover, and within the regional olivine‐bearing (ROB) unit in the Nili Fossae region surrounding this crater. It has

The high computational cost of Global Climate Models (GCMs) is a problem that limits their use in many areas. Recently an inverse climate modeling (InvCM) method, which fixes the global mean sea surface temperature (SST) and evolves the CO2 mixing ra

Photoionization Loss of Mercury's Sodium Exosphere: Seasonal Observations by MESSENGER and the THEMIS Telescope

Autor: Jim M. Raines, R. M. Dewey, Anna Milillo, J. M. Jasinski, Neil Murphy, James A. Slavin, Leonardo Regoli, Timothy A. Cassidy, V. Mangano

Publikováno v: Geophysical Research Letters

We present the first investigation and quantification of the photoionization loss process to Mercury's sodium exosphere from spacecraft and ground‐based observations. We analyze plasma and neutral sodium measurements from NASA's MESSENGER spacecraf

The Nature and Origins of Sub‐Neptune Size Planets

Autor: Sean N. Raymond, Jacob L. Bean, James E. Owen

Publikováno v: Journal of Geophysical Research. Planets

Planets intermediate in size between the Earth and Neptune, and orbiting closer to their host stars than Mercury does the Sun, are the most common type of planet revealed by exoplanet surveys over the last quarter century. Results from NASA's Kepler
