RM 1



RM 1 weighed about 21 kg and was approximately 167.6 cm long and 76.2 cm in diameter. It consisted of two cylindrical segments, (1) a solar cell array mounted around the fourth-stage motor cage of the Scout launch vehicle and (2) an electronics package encircling the cone-shaped adapter section atop the fourth-stage motor case. There were two experiments on board the RM 1 satellite. One was a radiation experiment consisting of an advanced radiation dosimetry system designed to measure and determine the type of radiation encountered and to convert the data instantly to conventional radiation dose units. The other experiment was a meteoroid experiment employing an improved detector system of thin film capacitors to obtain the number of meteoroid impacts and their direction and speed.
