Each year, Earth Day—April 22—marks the anniversary of the birth of the modern environmental movement in 1970. In this week's Ask an Expert Live, Space History curator Martin Collins remembers 1970 and the first “Earth Day.” Tune in on Facebook Live.
Planning to attend in person? Meet in the Looking at Earth 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.
