Investigating the Ages of Mercury’s Explosive Volcanic Deposits

Explosive volcanism on Mercury extended into Recent Geologic History, well after the presumed cessation of volcanic activity early in Mercury’s history.

Asteroid shapes from disruption and reaccumulation

Energetic disruption and reaccumulation produces top-shaped asteroids. More elongated asteroids like Eros and Itokawa form less commonly.

MESSENGER Advanced Products (MEAPs)

The MESSENGER Advanced Product (MEAP) project enhances the utility of MESSENGER data from the planet Mercury to the planetary science community.

Mapping Ice at Mercury’s South Pole

The uneven distribution of Mercury’s ice supports a comet impact origin

Impact Melting on Vesta at the Rheasilvia Antipode

Giant impact melting may have prolonged igneous activity on protoplanets

Effect of Re-impacting Debris on the Solidification of the Lunar Magma Ocean

Debris generated after the Moon-forming impact would have re-impacted the Moon, introducing additional heat transfer mechanisms to the conventional conductive-lid scenario.

Mercury’s Dark Secret

Low Reflectance Material on Mercury is enriched in carbon, and is native to Mercury.

Evidence for volatiles on the surface of 433 Eros and 1036 Ganymed

We have detected hydrated minerals on the two largest near-Earth asteroids, expected to be anhydrous. They likely are delivered by external sources such as solar wind or dust.

A Fresh Look at Older Mars Odyssey Neutron Spectrometer Data Yields a Surprise at the Equator

An improved-resolution map of the MONS epithermal neutron data was created and reveals substantial, unexpected H deposits near the equator.
