China launched out two astronauts into space on Monday. Their launch marks the begin of China's longest human space flight yet.

A carrier rocket sent the Shenzhou-11 spacecraft with astronaut Chen Dong and Jing Haipeng into space. The rocket was firing from the Jiuquan Satellite Launch Center in the Gobi desert. Chen is 37 years old. This is their first time in space. But Jing had done this before — it is his third space flight. He will turn 50 years old while orbits the Earth. “Their trip is a good start” —that is why Morris Jones told VOA. Jones is independent space expert from Australian.
