When the Cassini spacecraft plunges into Saturn on September 15, it will be the end of a wildly successful mission. The Cassini-Huygen's mission to the Saturn system revealed many secrets of Saturn, its rings, and its icy moons. Join us on Facebook Live as Emily Martin from the Museum's Center for Earth and Planetary Studies discusses the many accomplishments of the mission and its brave end.

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.
