The density of the lunar surface soil [PDF]
Journal of Geophysical Research, 1968 Until the landing of the Surveyor 1 spacecraft on the moon, it had been inferred from earth-based optical, thermal, radio, and radar observations that the surface f the moon consisted of material of low-bulk density (less than 1 g/cm^3) and high porosity.

Noble gases and nitrogen in material from asteroid Bennu
Meteoritics &Planetary Science, EarlyView.Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Microbial Endolithic Community at Meteor Crater
Meteoritics &Planetary Science, EarlyView.Abstract Postimpact recovery and evolution in response to climate changes produced a modern ecosystem at Meteor Crater dominated by a grassland and woodland of piñon and juniper, which has been used to evaluate floral and megafaunal consequences of impact cratering during the Phanerozoic Eon of complex life.

Effect of Soil Type on Running Performance of Small Lunar Rover
AerospaceIt is very easy for a small lunar rover to slip on the regolith of the lunar surface and become stuck. Previous studies have quantitatively evaluated the effects of wheel geometry, such as elliptical or eccentric wheels, on the performance of a rover ...
