An ancient impact splashed evidence of the Moon’s early mantle makeup onto its surface. Now researchers are piecing together models, maps, and samples to bring these mysteries to light.
Independent ground-based observations of the Moon confirm prior spacecraft observations that hydration at the lunar surface varies with temperature.
Astronomers model changes in Earth’s chemical signature over the past 4 billion years to improve the search for Earth-like exoplanets.
A new study shows how a warm, wet climate weathered rocks on early Mars.
Laboratory experiments that indicate rock particles can impede sliding along grain boundaries in ice may help researchers more accurately determine the composition of planetary ice masses.
A new study finds that Phobos includes chunks of Martian crust.
Irradiation-induced color changes in sodium chloride could reveal whether it came from ocean water mixing with surface water, a key component of the moon’s potential to support life.
NASA’s Curiosity rover explored the Kimberley region of Mars to search for signs that the planet was once habitable.
The consistently shallow depths of the depressions scattered across Mercury's surface suggest their morphology is not determined by the thickness of a volatile-rich outer layer.
New orbiter data support an important role for seasonal frost—not liquid water—in the formation of Martian gullies.
