BEIJING, May 31 (AP) - A three-man crew of astronauts will blast off in June for a three-month mission on China’s new space station, according to a space official who was the country's first astronaut in orbit.

The comments by Yang Liwei, the manned space programme’s deputy chief designer, to state television came as an automated spacecraft was launched with fuel and supplies for the Tianhe station.

The Tianhe, or Heavenly Harmony, is the third and largest space station launched by China’s increasingly ambitious space programme. Its core module was launched into orbit on Apr 29.

The Shenzhou 12 capsule carrying the crew will be launched from the Jiuquan base in China’s northwest next month, Yang said in comments broadcast on Saturday by China Central Television.

Yang, who orbited Earth in 2003, gave no details of the astronauts’ identities or a flight date and said the crew will come from the programme’s two earliest groups of astronauts.

Asked whether women would be in the crew, Yang said, “on Shenzhou 12 we don’t have them, but missions after that all will have them”.

The Tianzhou-2 spacecraft that docked with Tianhe on Sunday carried 6.8 tonnes of cargo including space suits, food and equipment for the astronauts and fuel for the station, according to the space programme.

The space agency plans a total of 11 launches through the end of next year to deliver two more modules for the 70-tonne station, supplies and the crew.

Beijing doesn’t participate in the International Space Station, largely due to US objections. Washington is wary of the Chinese programme’s secrecy and its military connections.

China has sent 11 astronauts, including two women, into space beginning with Yang’s flight in October 2003. The first female astronaut was Liu Yang in 2012.

All of China's astronauts to date have been pilots from the ruling Communist Party's military wing, the People's Liberation Army.

Astronauts on the Tianhe will practise making spacewalks with two people outside the hull at one time, according to Yang. China’s first spacewalk was made in 2008 by Zhai Zhigang outside the Shenzhou 7 capsule.

Also this month, the Chinese space programme landed a probe, the Tianwen-1, on Mars carrying a rover, the Zhurong.
