Progress 1 (Russian: Прогресс 1), was a Soviet unmanned Progress cargo spacecraft which was launched in 1978 to resupply the Salyut 6 space station. It was the maiden flight of the Progress spacecraft, and used the Progress 7K-TG configuration. It carried supplies for the EO-1 crew aboard Salyut 6, which consisted of Soviet cosmonauts Yuri Romanenko and Georgy Grechko. The cargo carried by Progress 1 also included equipment for conducting scientific research, and fuel for adjusting the station's orbit and performing manoeuvres.
