China launched two astronauts into space on October 17th, which marks the beginning of China’s longest human space flight yet.
    A carrier rocket sent a Shenzhou-11 spacecraft with astronauts Chen Dong and Jing Haipeng into space.(5)The rocket was fired from the Jiuquan Satellite Launch Centre in the Gobi Desert. Chen is 37 years old. This is his first time in space. But Jing has done this before—it is his third space flight.
    Their trip is off to a good start. That is what Morris Jones told VOA. Jones is an independent space expert from Australia. He says China plans to launch a special module around 2018.(6)A module is a part of a space vehicle that can work independently. He says that piece will be at the centre of a new space station.
    China hopes to have the space station completed by 2022. Compared to the International Space Station, the Chinese space station will have less than half its volume, and a lot less complexity.(7)China also plans to land a rover vehicle on Mars by 2020. Until now, China had completed a total of five manned space missions. And, in 2003, it successfully landed a probe on the moon.
