The re-entry module of China's Shenzhou-7 spacecraft arrived in Beijing Tuesday afternoon, two days after its safe landing in northern China's Inner Mongolia.

The capsule was delivered to the China Academy of Space Technology or CAST, where the spacecraft was manufactured, for checks and further studies.

CAST experts will open the capsule on Wednesday morning and conduct further examinations on the capsule and the parachute that helped the craft's safe landing.

Song Liding is the deputy research head of the CAST.

"First of all, we will carry out technical check-ups for the module. And we will also continue our experiments on the items which were carried up into space by the module."

The test sample of solid lubricant fetched by China's first spacewalker Zhai Zhigang from the outside of the orbital module during his 20-minute spacewalk will be handed to the Chinese Academy of Sciences and studied there.

Back from a 68-hour successful mission that included the country's maiden spacewalk, the Shenzhou-7 re-entry module carrying three taikonauts landed safely by parachute on Sunday in China's northern grassland.

Other tasks of the mission included carrying out trials of satellite data relay and releasing a 40-kilogram companion satellite.
