400公里高空上演“太空泊车”！我国成功实施问天实验舱转位

据中国载人航天工程办公室消息：北京时间2022年9月30日12时44分，经过约1小时的天地协同，问天实验舱完成转位。

这是我国首次利用转位机构在轨实施大体量舱段转位操作。问天实验舱转位完成后，空间站组合体由两舱“一”字构型转变为两舱“L”构型。后续，空间站组合体将以“L”字构型在轨飞行，等待梦天实验舱发射、交会对接后，还将转位形成空间站三舱“T”字构型组合体。

China completes a transposition of the Wentian lab module using the large robotic arm at 12:44 p.m. (BJT) on Friday, according to the China Manned Space Agency (CMS).

It is the first time that China has used a transposition mechanism to implement a large volume module transposition in orbit. 

During the transposition process, the Wentian lab module was first put into a certain mode setting, followed by separation from the Tianhe core module, and then was docked on the side of the node cabin.

China's space station is now in an L-shaped combo and will continue to operate in orbit until the arrival of the Mengtian lab module, China's second space lab, after which the country will complete the T-shaped three-module structure of its space station.
