Spectral data from by the 1994 mission of the Clementine spacecraft provided a wealth of information about the mineralogy of the Moon's surface. Join us on Facebook Live as Center for Earth and Planetary Science geologist Gareth Morgan discusses how this data enabled a greater understanding of the volcanic history of the Moon.  

Planning to attend in-person? Meet in the Lunar Exploration Vehicles gallery. 


Every Wednesday at 12:30 p.m. we will go live on the National Air and Space Museum Facebook page with an Ask an Expert talk. We’ll select a different aviation or space topic each week, and a Museum staff member will discuss the history, stories, or personalities related to a specific artifact or exhibition in the Museum. Tune in on Facebook Live each week to join the talk and ask our experts questions.
