The Earth's core is inferred to be iron-rich from (1) the core's density as deduced from the core's size and the planet'smoment of inertia, (2) computer models of the bulk composition of the Earth and compared with the composition of the chondritic meteorites from which the Earth for...

Density:npin [per cc] All vector quanties are measured in Mars Solar Orbital (MSO) coordinates. The dataset(s) used in the current iteration of this model are from a combined SWIA and MAG (MAVEN instruments) data source, seeHalekas+2017,Halekas+2015,Connerney+2015andonlinefor original dat...
In the NASA feature, Slaba said, “In space, outside Earth’s protective magnetic field and atmosphere, there is a very complex radiation field of protons, and all the elements on the periodic table are coming in at energies approaching the speed of light.” SpaceX’s founder and CEO, El...
In the present, such an escape mainly proceeds via thermal evaporation (Jeans escape), which is sensitive to the atomic H density and temperature at the Martian exobase and presents a range of exciting variabilities. Under normal conditions, atomic H is mainly produced via ionospheric chemistry, ...
EMM will characterize the spatial structure of hydrogen and oxygen density and escape in the Martian exosphere and their variability with respect to season and solar activity. This will be achieved using densities and temperatures derived from UV brightnesses observed by the EMUS instrument and will ...

Mars hosts the solar system’s largest volcanoes. Although their size and impact crater density indicate continued activity over billions of years, their formation rates are poorly understood. Here we quantify the growth rate of a Martian volcano by 40Ar
Earth. In general, the effect that gravity had on electrolysis was found to become more pronounced as the current density was increased. The impact on product output in the studied system is more significant due to the relationship between overpotential and current density. This could be mitigated...
