The Spark of a New Era

NASA - National Aeronautics and Space AdministrationPasadena, CA – Seventy-five years ago this Halloween, at 9:00am, a truck from the California Institute of Technology turned on to a road owned by the Pasadena Water Department and after heading down a small hill came to a stop. Its tired occupants – they had spent the night before preparing and had only three hours sleep – clambered out and began the laborious job of carrying a truck full of cumbersome test equipment another 400 yards into the dirt and scruffy brush of Pasadena’s Arroyo Seco.

They were there in an isolated, dry, scrub-strewn gulch three miles north of the Rose Bowl to scientifically measure the thrust developed by one of the world’s first liquid-fueled rocket motors. They were there to accurately calculate the efficiency of the motor. They were there because, there, they most likely would not kill anyone – except perhaps themselves.
