Meet three of the women who ascended through glass ceilings during the Apollo program.

To commemorate the 50th anniversary of the Apollo missions to the Moon, the 2019 John H. Glenn Lecture in Space History will feature three outstanding women of that era whose work was essential to those remarkable achievements. Although in plain view in photos and among their peers, these women until recently have been relatively overlooked in public perceptions of the masculine nature of spaceflight in the 1960s and 70s.

The John H. Glenn Lecture in Space History is made possible by the generous support of Boeing.
