Sputnik 3

The scientific satellite carried a large array of instruments for geophysical research of the upper atmosphere and near space.

[1] On 30 January 1956, the USSR Council of Ministers approved a project to launch an artificial Earth satellite using the R-7 rocket.

[2] It was intended to be launched during the International Geophysical Year as the first satellite by the Soviet Union but ended up being the third due to problems developing the extensive scientific experiments and their telemetry system.

The creation and use of pressurized equipment, long-range communications systems, automated switches, and a metal construct to work in Earth orbit were all uncharted territories.

The strap-on boosters broke away from the core and the entire launch vehicle tumbled to earth 224 km (139 mi) downrange.

Ground crews monitoring radar tracking data from the booster noticed the trajectory angle change to negative numbers, followed by a complete loss of signal.

Since the booster did not carry sufficient instrumentation to determine the source of the vibrations, which ultimately proved to be a phenomenon resulting from the propellant tanks emptying, it would end up being a recurring problem on lunar probe launches later in the year.

It was taken back to the Baikonur Cosmodrome for refurbishment, but an electrical short started a fire inside the electronics compartment and it could not be reused.
