A PSLV C60 rocket from the Indian Space Research Organization (ISRO) launched the Space Docking Experiment (SpaDeX) mission into a 350 km (217.5 mi) circular orbit. Onboard were the SPADEX-A and SPADEX-B spacecraft, which will demonstrate on orbit rendezvous, docking and undocking capabilities using small satellites. Also on board the mission was the PSLV Orbital Experimental Module-4 (POEM-4), an orbital platform which hosted 14 ISRO payloads and 10 from other companies or institutions.
