Amorphous materials generated from sulfur and chloride salts by electrostatic discharge in a Mars chamber suggest widespread electrical processes during dust activities.
Meteorite NWA 11004 contains evidence of melting preceding an impact dated to 4546±36 Ma. Short lived radioactive decay had already heated the parent body of this meteorite before the impact.
Great Britain’s largest impact crater likely lies in the Scottish Highlands. Scientists dispute whether it’s to the west or the east.
Curiosity’s two-step heating experiment of mudstone at Gale crater reveals minerals that formed in the presence of water less than 3 billion years ago.
A better equation of state for silica will help planetary scientists accurately constrain the giant impacts that have shaped our solar system.
Spectral data from NASA's MESSENGER spacecraft indicate that the properties of the depressions on Mercury's surface can vary within a single crater and that these differences may correlate to age.
