Short Story # 6 The Lady Astronaut of Mars by Mary Robinette Kowal
What does an astronaut's retirement look like? In this realistically imagined novelette, Kowal brings to life a retired lady astronaut, living in the Martian colony she helped found. When her age and gender bring one last opportunity to go the stars though, her husband's debilitating disease presents an agonizing obstacle. The story pulls no surprises, but comments gently on double standards and the unique trials of aging.
