It was night in India when the two satellites of the SpaDeX (Space Docking Experiment) mission were launched from the Satish Dhawan Space Center atop a PSLV-CA rocket. The two satellites separated from the rocket’s final stage and entered a circular orbit at an altitude of about 475 kilometers. Another 24 experiments were launched on the same mission, but the SpaDeX satellites are the most important because they will serve to test the docking technologies necessary for the progress of the Indian space program.
