天舟一号的商业化观察货运飞船是长期载人航天活动的关键因素,主要为空间站运送消耗物品、推进剂、维修设备、维修器材和试验载荷设备等。天舟一号的成功,意味着中国的空间站可以进入长期有人值守的运行模式。“天舟”作为货运飞船,不需要生命保障系统和返回着陆系统,不但成本显著降低,载货能力也比“神舟”飞船大得多。从经济角度衡量,维持一名航天员在轨生活一天的成本大幅度降 Commercialization of the TZS One of the key elements of long-term manned space activities is cargo spacecraft carrying consumables, propellants, maintenance equipment, maintenance equipment and test load equipment. The success of the Tiantan One means that the Chinese space station can enter into a long-term manned operation mode. As a cargo spacecraft, “Tian Zhou” does not need a life support system and a return landing system. It not only significantly reduces the cost but also has a significantly larger cargo carrying capacity than the “Shenzhou” spacecraft. From an economic point of view, the cost of maintaining an astronaut in orbit for one day is significantly reduced
