Beijing - China could send astronauts to its space station for more than a year at a time once it goes operational in 2022, a senior project designer told state media.

The country's second space lab, the Tiangong-2 - or Heavenly Palace-2 - blasted off from the Gobi desert on Thursday and is expected to operate for at least two years, the latest stage of the Asia's giant's ambitious space programme.

Construction on a space station will start as early as 2017 and take about three years before it enters into service in 2022, the official Xinhua news agency reported, citing Zhu Zongpeng, chief designer of the space lab system.

Astronauts could be stationed in orbit for missions that last for more than a year in the facility, which has an initial designed life of at least 10 years, Zhu said.

The longest single stay in space by a human so far is 437 days by Russian cosmonaut Valeri Polyakov.

Global stature

The Chinese space station will weigh over 60 tons, much smaller than the 420 tons of the International Space Station and consist of a core module attached to two space labs, Xinhua said.

It will normally accommodate three astronauts at a time but has a maximum capacity of six.

China is pouring billions into its space programme and working to catch up with the US and Europe.

Beijing sees its military-run space programme as symbolising the country's progress and a marker of its rising global stature.

The nation's first lunar rover was launched in late 2013 and while it was beset by mechanical troubles it far outlived its expected lifespan, finally shutting down only last month.
