Chang'e 5-T1 (嫦娥五号T1; Cháng'é wǔhào T1) was an preparatory robotic lunar mission launched by China National Space Administration on 23 October 2014. It was in preparation for Chang'e 5, launched in 2020, the first sample-return mission of the Chinese Lunar Exploration Program. Launched by a Long March 3C on a free-return trajectory around the Moon, the mission consisted of a return capsule, which landed on Earth after eight days, and a service module lunar orbiter, which remained active until at least 2018. The return capsule of Chang'e 5-T1, named Xiaofei (小飞; 'little flyer'), tested the Chang'e 5 design's atmospheric re-entry capacity, landing eight days later, on 31 October, in the Dorbod Banner landing site in Inner Mongolia, also used by the China Manned Space Program.
