Indian Space Research Organisation's (ISRO) Polar Satellite Launch Vehicle (PSLV)-C60 rocket carrying two spacecraft that would aid in demonstration of space docking, a critical technology for future space missions, lifted off from the spaceport in Sriharikota, Andhra Pradesh, on Monday night.

Billed as a prelude to ISRO's setting up its own Space Station by 2035, the 44.5-metre-tall PSLV carried Spacecrafts A and B, each weighing 220kg that would help in space docking, satellite servicing and interplanetary missions.
