Dr. Jupiter Cheng awarded the 2023 Pellas-Ryder Award


"Congratulations to Dr. Cheng (UGA) and co-winner Dr. Denton (Purdue) for this highly deserved honor and for leading these impressive studies!"

Hui Ching Jupiter Cheng, who obtained a Ph.D. in 2023 from the University of Georgia, Athens, GA, USA, is a co-winner of the 2023 Pellas-Ryder Award for the paper entitled “Structural relationships in and around the Rheasilvia basin on Vesta” published in the Journal of Structural Geology in 2022. Jupiter performed a thorough, detailed structural analysis of the basin, and found, contrary to previous interpretations, that the Divalia Fossae cross-cut the basin and are not concentric around the basin center, and therefore formed after it and are not directly related to the impact that formed the basin. This work is likely to inspire follow-up studies, leading to reexamination of the formation of the Rheasilvia basin and improvement of our understanding of Vesta.


The Pellas-Ryder Award is a jointly sponsored by the Meteoritical Society and the Planetary Geology Division of the Geological Society of America and honors outstanding first author planetary science papers by students.
