The Rouse number and Brunt-V盲is盲l盲 frequency are used to estimate the wavelength of internal gravity waves in a density-stratified current, which allows us to predict deposit dune wavelengths. The model predicts realistic runout distances and bedform wavelengths for several well-documented field...
The suite of volcanic, structural, geochemical, geophysical and topographic observations within and around the Eridania basins can be understood in the context of vertical tectonics. Before plate tectonics took hold on the Archaean Earth circa 2.5 billion years ago, crustal evolution on this planet ...

"Most notable was a sharp drop in air density — about a 7% deviation below what was observed pre-dust storm," Jonathan Bapst and Michael Mischna, of Ingenuity's weather/environment team, said in a statement. "This observed decrease would have put density below the lower threshold of safe...
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's moment 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 ...
It's not easy designing a new helicopter, especially if that new helicopter has to survive a ride on a rocket into space. NASA's Ingenuity helicopter is the first machine aerial vehicle to fly on a planet outside Earth. Ingenuity was designed specificall
Given the absence of a priori atmospheric information in Jezero crater, and the need to understand both density and wind conditions in the local environment, a significant modeling effort was pursued, prior to landing, in order to constrain the expected flight environment (e.g., Mischna et al...
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...
Also, since the average density of Mars’ atmosphere is about two orders of magnitude lower than Earth’s, little-to-no burning-up due to aerodynamic heating is expected. It would be highly undesirable to let a large uncontrolled satellite plunge on the solid surface, where infrastructure (or...
