Shenzhou-9 spacecraft to return Friday morning

BEIJING, June 28 (Xinhua) -- The Shenzhou-9 manned spacecraft will return to Earth around 10 a.m. Beijing Time Friday, a spokesperson for China's manned space program announced here Thursday.

A manual operation successfully separated the Shenzhou-9 spacecraft and the Tiangong-1 lab module Thursday morning, according to the Beijing Aerospace Control Center.

It was the first time for China's spacecraft and target module to be manually disjoined.

The three Chinese astronauts returned to the Shenzhou-9 from the Tiangong-1 at 6 a.m. Beijing Time Thursday, in order to prepare for the manual separation attempt.

Liu Wang, one of the astronauts, conducted the operation to separate Shenzhou-9 and the orbiting Tiangong-1. He will continue to manually operate and direct the spacecraft to a safe distance from the lab module.

During their stay in the Tiangong-1, all experiments and tests were finished as scheduled and produced valuable data, said Chen Shanguang, chief commander of the mission's astronaut system.

"These data will help us improve technologies for astronauts' future, long-term stays in a space station," he said.

All data and samples have been moved to the return capsule of the spacecraft, and the lab module has been restored to its pre-docking status, said the control center.

The Tiangong-1 will return to its previous orbit and wait for another spacecraft.

The lab module is designed to operate for two years and host six docking procedures. It has been operating for 272 days and undergone four docking procedures with Shenzhou-8 and Shenzhou-9 spaceships, to date.

"Based on current conditions, the service of the Tiangong-1 can be extended," said He Yu, chief commander of the Shenzhou-9 spacecraft. "It has consumed less than one-fourth of its fuel and no back-up systems have been used."

If the systems were improved and its operation was under careful monitoring and control, the service could be much longer, he said.

"If Tiangong-1 was in perfect shape, it could work side by side with the Tiangong-2, which will be launched in the future," he said.
