China prepares for first spacewalk

Astronauts aboard China’s Shenzhou 7 spacecraft are readying spacesuits for Saturday’s spacewalk – the country’s first ever.

Prepping the two suits – one Chinese, one Russian – takes around 12 hours, and includes booting up the power, life support, and other systems and synchronising them, said Wang Zhaoyao, deputy director of China’s manned space program office.
