The Calculating Stars by Mary Robinette Kowal
I'm reading through the Hugo nominees this summer, and one of the nominees for Best Novel is The Calculating Stars. It's about women in space science, and as astronauts, in the 1950s. It is a gentle, but lovely, exploration of race, religion, and especially gender. It follows a group of female pilots as they attempt to gain acceptance as astronauts. It's the first in a series called The Lady Astronauts.
@pyjamaviking , sounds interesting! Visiting the Space and Rocket Center in Huntsville recently made me want to learn more about not just about space (which I always want to learn more about), but also the astronauts. Mae Jemison was the first African American woman in space, and she's from my state of Alabama.
