While in orbit, the three astronauts completed two docking tests with the Tiangong-1 experimental space lab.

在轨飞行期间，三名航天员完成了与天宫一号空间实验室的两次交会对接任务。

Later that month, Virgin Galactic’s experimental space vehicle SpaceShip Two broke up in the middle of a test flight, killing one of the two pilots.

当月晚些时候，维珍银河的实验太空飞船SpaceShip2在测试航行中爆炸，导致两名宇航员死亡。

Compared with eight years ago, the Tianhe space station core module is much larger than the experimental space lab Tiangong-1, and way more advanced, Pang Zhihao, a Beijing-based space expert, told the Global Times.

与八年前相比， 天河空间站核心模块比实验空间实验室天宫一号大得多， 而且更先进， 北京的空间专家庞志浩告诉环球时报。
