Mehdi Benna, CSST, Confirms Presence of Neon in Moon’s Exosphere

Published: Aug 19, 2015

Mehdi Benna, a Center for Space Science and Technology planetary scientist, is the lead author of a paper confirming the presence of neon in the Moon’s exosphere. The paper was published in Geophysical Research Letters and has received widespread international media attention.

Mehdi BennaIn the paper, Benna describes observations from NASA’s Lunar Atmosphere and Dust Environment Explorer, known as LADEE. Though many have suspected that the Moon’s exosphere contained neon, Benna’s paper is the first to confirm its presence. “The presence of neon in the exosphere of the moon has been a subject of speculation since the Apollo missions, but no credible detections were made,” Benna said. “We were very pleased to not only finally confirm its presence, but to show that it is relatively abundant.”

Benna spoke to Discovery News about the importance of the finding, saying, “It’s critical to learn about the lunar exosphere before sustained human exploration substantially alters it.”
