WebHistory. The idea of electric propulsion for spacecraft was introduced in 1911 by Konstantin Tsiolkovsky. Earlier, Robert Goddard had noted such a possibility in his personal notebook. On 15 May 1929, the Soviet research laboratory Gas Dynamics Laboratory (GDL) commenced development of electric rocket engines. Headed by Valentin Glushko, in the … WebIn chronological order, spacecraft are listed equipped with electric space propulsion. This includes both cruise engines and/or thrusters for attitude and orbit control. It is not specified whether the given engine is the sole means of propulsion or whether other types of engine are also used on a spacecraft.
