China is gunning ahead with its ambitions of grabbing a fair share of the space pie and in the latest attempt geared towards that goal, the country is testing a self-sustaining space station.
For the test university students have been recruited who will be spending 200 days behind sealed steel doors of two bunkers in a Beijing suburb. Students will be checking out how it feels to live in a space station on another planet, recycling everything from plant cuttings to urine alongside a number of other experiments geared towards understanding the hurdles in deep space missions.
The students are part of a project aimed at creating a self-sustaining ecosystem that provides everything humans need to survive. Four students from Beijing University of Aeronautics and Astronautics entered the Lunar Palace-1 on Sunday with the aim of living self-sufficiently for 200 days.
They say they are happy to act as human guinea-pigs if it means getting closer to their dream of becoming astronauts.
President Xi Jinping wants China to become a global power in space exploration, with plans to send the first probe to the dark side of the moon by 2018 and to put astronauts on the moon by 2036. The Lunar Palace 365 experiment may allow them to stay there for extended periods.
For Liu Hong, a professor at Beijing University of Aeronautics and Astronautics and the project’s principal architect, said everything needed for human survival had been carefully calculated.
“We’ve designed it so the oxygen (produced by plants at the station) is exactly enough to satisfy the humans, the animals, and the organisms that break down the waste materials,” she said.
But satisfying physical needs is only one part of the experiment, Liu said. Charting the mental impact of confinement in a small space for such a long time is equally crucial.
The project’s support team has found mapping out a specific set of daily tasks for the students is one way that helps them to remain happy. But the 200-day group will also be tested to see how they react to living a for period of time without sunlight. The project’s team declined to elaborate.
“We did this experiment with animals… so we want to see how much impact it will have on people,” Liu, the professor, said.
