Workers construct a replica of the Chinese prototype space lab Tiangong-1 in Shijiazhuang, North China’s Hebei province, April 15, 2015. Xu Weilong, a fan of model airplanes, has led a team in building the real-size mock-up over four months. Inside, the cabin is divided into parts for navigation, a living room, kitchen, repair room, gym, and environment control center, as in the real space lab. Xu also has had a toilet, water recycling system, and sleeping zone installed in the device. (Photo: China News Service/Zhai Rujia)
