On November 1st,2011，I watched the live launch of the unmanned spacecraft，Shenzhou­8，on CCTV.At 5 in the early morning，S henzhou­8 was launched perfectly into the air.After being launched，Shenzhou­8 would be docked with Tiangong­1，which had already been launched on September 20th,2011.The journey of Shenzhou­8 will be followed by the launches of Shenzhou­9 and Shenzhou­10，and the three will together form China's first space laboratory.I'm so proud of the achievements our country has made in space technology.
