A researcher at the NASA Lewis Research Center manipulates cartridge pellets and a strain gauge target as part of a study on the impact of micrometeorites striking space vehicles. Early in the space program NASA researchers were concerned that small micrometeorites would penetrate spacecraft, injure engines, or damage solar arrays. In response, researchers worked to develop stronger materials to withstand meteorite strikes and screens to block the objects. NASA launched a series of experimental spacecraft into orbit with foil shields that were used to determine the number of meteorite strikes. By the early 1960s the experiments and computer modelling efforts revealed that the micrometeoroid threat was lower than previously anticipated.
