The competition heats up: A Chinese state media report just released included footage showing China’s unmanned cargo freighter, Tianzhou-1, as engineers prepare it for its April launch to their test space station module, Tiangong-2.
Two important take-aways from this report. First, note in the simulation showing the docking of the freighter to Tiangong-2 the size comparison. The two craft are almost the same size, showing that Tiangong-2 really is nothing more than a test module, not large enough for long sustained space station operations. The freighter meanwhile is quite substantial.
Second, the report says they are aiming for a 2018 launch of the first module of their full size station.
