材料
The three astronauts in the core module of the Tiangong space station may have escaped Earth's gravity, but one chore has followed them into orbit——housework. The jobs of cooking and cleaning never have a cessation, but technology helping keep them well fed and their temporary home tidy.
In what passes for a kitchen in their cramped quarters, the astronauts have a microwave oven specially designed for use in space, which was carried by the space cargo craft Tianzhou 2. Other appliances include high-tech vacuum bags that safely store waste and kill ill odors.
But eating is the first order of business for hungry space station residents. "The oven was designed to provide healthy food for astronauts in the core module of the space station-to help them prepare nutritious and satisfying food," said Li Feng, an engineer with the Galanz Group's research and development department.
The microwave in the module has been modified to cope with conditions experienced during the mission. "During the rocket's liftoff, the oven needed to withstand high-frequency turbulence. It's expected to work continuously for 10 years in space," Li said. The oven has a more efficient magnetron, the internal device that generates microwaves, and a special power supply to reduce its weight, reducing impact of weightlessness.
There are around 120 kinds of food available for astronauts meals on the space station. Zongzi, spiced bean curd, fried noodles with shredded pork, bamboo shoots and brown sugar glutinous rice cake are all on the menu, a newspaper in Zhejiang province, where the meals were packaged.
Other Chinese produced high-tech innovations are in the module to help make the astronauts lives more comfortable. Guangdong Taili Technology Group, which specializes in vacuum technology, has developed special bags to deal with trash.
"In view of the weightless environment, vacuum storage bags are a necessary convenience," said Wang Zhenchang, chief engineer at the Taili Group.
Soiled clothes, food packaging and other waste items are classified and carefully collected in a device designed for the purpose, Wang said. Garbage containment is a serious health issue in space as bacterial pathogens floating in the air can threaten the astronauts' health.
