If you think Sally Ride was the first American woman in space (1983), listen up; more hidden figures in the space program are about to emerge. In her book, “THE MERCURY 13,” journalist, author, and editor Martha Ackmann details the true story of a group of women who were secretly trained for spaceflight in the 1960s. But they never left earth, due to politics and cultural arguments. The tale of how these talented women who performed as well, or better than, their male counterparts, is amazing and makes for a great way to celebrate Women’s History Month.
