NASA’s Curiosity rover found siderite, an iron carbonate mineral, within the rocky layers of Mount Sharp in Mars’ Gale Crater. This discovery could provide an answer to the mystery of what happened to ...

Topographic surface degradation on Mercury is predicted to occur at almost double the rate observed on the Moon, but the exact cause of this enhancement is currently unknown. Impact cratering is ...

Type Ia supernovae (SNe Ia) are the explosive, thermonuclear deaths of white dwarf stars in multi-star systems. Despite decades of intensive study, the true nature of their progenitors and the ...

A mysterious object discovered in the main asteroid belt in 2021 was determined to be a main-belt comet by Planetary Science Institute Senior Scientist Henry Hsieh, Scott Sheppard of the Carnegie ...

Our objective is to improve interpretation of in situ and remote-sensing data of Mercury. We will use updated exosphere and spectrophotometric models that incorporate new data from our proposed ...

Year 1 Primm will remotely monitor the chamber system as it is running experiments and log the different experiments performed to track the work flow. Year 2 Primm will continue to monitor the ...

A current hypothesis for the early climate of Mars postulates that the southern highlands were covered by a cold-locked ice sheet (e.g., recent works by Head, Fastook, Wadsworth and others). This is ...
