BEIJING, May 6 (Xinhua) -- A flexible and inflatable cargo return capsule that China sent into space for test for the first time operated abnormally during its return to the ground on Wednesday, according to the China Manned Space Agency.

Aboard the country's new large carrier rocket Long March-5B, the test capsule was launched from the Wenchang Space Launch Center on the coast of southern China's island province of Hainan on Tuesday.

Experts are now analyzing the relevant data, the agency said.

The unmanned spaceship, sent into space along with the capsule on Tuesday, remains in stable condition and is carrying out tasks as planned in the orbit, said the space agency.

The spaceship is a trial version for a manned craft designed for missions to build an orbiting space station.
