空间站
space station
The completion of the space station will provide a broader scope for commercial space development and commercial operation can be a beneficial supplement of the station's functioning.
China's space station, expected to be completed around 2022, will operate in the low-Earth orbit at an altitude from 340 km to 450 km for more than 10 years, supporting large-scale scientific, technological and application experiments.
空间站的建成将为商业航天提供更为广阔的发展空间，商业化运作也可以为空间站运营提供有益的补充。
中国空间站预计在2022年前后建成，将在高度340至450公里的近地轨道运行，在轨飞行可达10年以上，支持开展大规模的空间科学实验、技术试验和空间应用等活动。
