China's cargo spacecraft Tianzhou 4, carrying supplies for the upcoming Shenzhou XIV crewed mission, successfully docked with the combination of the space station core module Tianhe and the Tianzhou 3 cargo craft on Tuesday, according to the China Manned Space Agency.
Carrying nearly 6 metric tons of propellants and materials, including more than 200 packages, the Tianzhou 4 is tasked with supporting the upcoming Shenzhou XIV mission, during which a three-member crew is expected to stay six months inside the Tiangong station.
