The development of a spacecraft electric powered subsurface sampler for drilling a 1-1/4 inch diameter hole in the lunar surface to a maximum depth of 5 feet is discussed. The unit is designed to deliver lunar soil samples from selected depths to a sample analysis system and positions a geophysical probe in the hole. Automatic operation, by command from an earth control station on the basis of telemetered information is planned. The system includes four electric motor powered drives designed for operation in a very high vacuum. The total weight of this mechanism is 26.9 pounds.
