The women who worked at the Jet Propulsion Laboratory during its formative decades, from the 1950s to the 1980s, were a vital part of a team that revolutionized rockets and space exploration. Their calculations controlled the trajectories and plotted the courses of NASA’s satellites, probes and exploratory rangers – a task similar to calculating how to shoot an arrow at a moving target from millions of miles away. In short, it was an almost superhuman feat. Now, in our more open-minded times, their accomplishments are finally getting the recognition they truly deserve.
