Progress is the cargo spacecraft for unmanned missions to the ISS and previously to Mir.

It was an unmanned cargo spacecraft carrying a mixture of pressurised and unpressurised cargo to the space station.

Progress M-9 was a Soviet unmanned cargo spacecraft which was launched in 1991 to resupply the Mir space station.

They also operate manned and cargo spacecraft which continues after US Shuttle program ended.

After Mir's collision with a cargo spacecraft on June 25, all that changed.

Unmanned cargo spacecraft will dock with the station, allowing for resupply and long-term human habitation.

The fourth Salyut 6 expedition deployed a 10-meter radio-telescope antenna delivered by an uncrewed cargo spacecraft.

Furthermore, modified versions of Tiangong-1 will be used as robotic cargo spacecraft to resupply this station.

Modified versions of Tiangong spacecraft will be used as robotic cargo spacecraft to resupply this station.

The launch mass of the Tiangong-1-derived cargo spacecraft is expected to be around 13,000 kg with a payload of around 6,000 kg.
