Growing up without much interest in science, Ellen Ochoa discovered physics in college and studied electrical engineering. Sally Ride's historic example inspired Ochoa to enter NASA's astronaut program and in time, she made history as the first Hispanic woman in space. This book in the Notable Hispanic Americans series tells the extraordinary story of a trailblazing woman who played an important role on four space shuttle missions, became a NASA leader in a time of tragedy and change, and devoted her post-space career to encouraging others to study STEM and reach for the stars.
