In honor of Black History Month, this week's Ask an Expert Live will be about NASA astronaut Guion "Guy" Bluford, the first African American in space. Join us on Facebook Live as space history curator Cathleen Lewis talks about this veteran of four space flights who logged over 688 hours in space. 

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.
