Watched by President Xi Jinping, Shenzhou-10 (Divine Craft) spaceship carrying the three astronauts blasted off from the Jiuquan Satellite Launch Centre in the Gobi Desert for a 15-day-long mission during which it would dock with Tiangong-1 space lab orbiting round the Earth and conduct a host of experiments.
"I now announce the launch was a great success," said Zhang Youxia, the manned space programme's chief commander.
The text-book launch of Shenzhou-10, atop an upgraded Long March-2F carrier rocket, was telecast live. While state-run newspapers gave the mission blanket coverage.
Soon after the launch, Xi, also General Secretary of the ruling Communist Party, congratulated Chinese scientists on the successful launch of the Shenzhou-10 manned spacecraft.

Xi came among space scientists at the command centre in Jiuquan, shook hands with those participating in the programme and sent his warm greetings to them.
"You made Chinese people feel proud of ourselves," Xi told the astronauts at a see-off ceremony ahead of the launch.
China is eyeing to join a select club of countries which have carried out more than one manned space missions. At present, the US and Russia are the other two nations to send independently maintained space stations into orbit.
The space mission is a source of huge national pride for the communist nation, reflecting its ambition to be among the world's leading powers.
This is China's fifth manned mission and would last a fortnight compared to last year's 13 days.
