BEIJING, Oct. 23 (Xinhua) -- An accompanying satellite was launched from space lab Tiangong-2 at 7:31 a.m. on Sunday.

The satellite, which weighs 47 kilograms and is the size of a printer, was launched into space aboard Tiangong-2 on Sept. 15.

The micro satellite is able to conduct efficient orbit control, process tasks autonomously and transmit data at high speeds, with stronger capabilities compared with the accompanying satellite of the Shenzhou-7 spacecraft.

At the end of October, the satellite will orbit close to Tiangong-2 and Shenzhou-11 and take photos with the high-resolution camera installed on it.

The accompanying satellite will also carry out space experiments with Tiangong-2 to expand the use of space.

The Shenzhou-11 spacecraft carried two astronauts into space on Oct. 17 from northwest China's Gobi Desert. It docked with Tiangong-2 two days later.
