The Tianzhou-1 spacecraft will be launched by a Long March-7 rocket. This will be the rocket's first mission since its debut launch last June. The Long March-7 is a new-generation medium-sized carrier rocket. It boasts significant improvements in terms of design, structure, and flight time, among other aspects. Its carrying capacity can reach as much as 14 tons, giving it a strong advantage over other medium-sized rockets. Its main fuels are liquid oxygen and kerosene, which enable stronger thrust and are more environmentally-friendly.
