The dream of soaring into the sky has inspired humankind for ages. Only at the beginning of the 20th century did this dream finally come true, with airplanes flying in the low atmosphere. Space flight was the next challenge. Before space exploration became a collaborative effort, the space race was driven by competition: engineers and scientists across the globe strove to design spaceships that could venture into space. Many brilliant minds came together to accomplish this feat. Katherine Johnson was one key figure, mastering extraordinary calculations that made it possible for the first humans to safely land on the Moon.
