The Spacecraft
The spacecraft contained radio equipment, a tracking transmitter, a telemetry system, five different sets of scientific devices for studying interplanetary space (including a magnetometer, geiger counter, scintillation counter, and micrometeorite detector), and other equipment. The total final (with fuel spent) mass of the third (upper) stage rocket with the spacecraft was 1472 kg.
It was intended that after a completion of its scientific mission of in-flight measurements, Luna-1 would crash into the Moon, delivering two metallic pennants with the Soviet coat of arms that were included into its package.
