A team of scientists are carrying out a project at the University of Greenwich in London. They are trying to find ways to make food on Mars (火星) in the future. The project is called Feeding Mars. It tries to use water, fish and fish waste to grow fruit and vegetables on Mars.
It would take at least 21 months to reach Mars, learn about its surface and return to Earth. So it would be a big help if the spacemen could grow fresh food on Mars itself.
Farming on Mars, however, will be very hard. There's plenty of water that could be taken from ice just below the surface, but the land on Mars is missing the nutrients (养分) that living things need. The team says that they could solve the problem by growing plants and fish together. Fish waste can then be used to provide nutrients for plants.
"It is expected that you can grow lots of food, such as vegetables, salads, teas and medicinal plants on Mars," said Dr Benz Kotzen, who leads the project. "You can even harvest (捕获) fish for food then."
Wukong, Tiangong, Tianwen… Do you know where the names of Chinese space programs come from?
Wukong, the Dark Matter Particle Explorer satellite (暗物质粒子探测卫星), is named after Chinese superhero Monkey King. According to Journey to the West, Monkey King has a pair of sharp eyes which can tell the difference between good and evil. The Wukong satellite is just as sharp-eyed as Monkey King to help scientists search for dark matter in space.
The name of the space station, Tiangong, means "Heavenly Palace". In Chinese myths (神话), this is the home of Tian Di. Now Tiangong Space Station is a home for Chinese astronauts in space. And China welcomes foreign astronauts to Tiangong so that they can work together.
Tianwen, China's Mars missions (任务), gets its name from the poem Tianwen by Qu Yuan. Qu Yuan is a well-known poet from ancient China. In Tianwen, he had the questions about the sky, stars, nature, myths and the real world, showing his hunger for truth. Perhaps the Tianwen missions will end up answering some of Qu Yuan's questions.
If you look into more names of Chinese space programs, you will find that they all have beautiful meanings. We, the Chinese people, have a long-cherished (珍藏已久的) space dream. So the naming of Chinese space programs is taken very seriously.

5 Questions for Jose Hernandez As a kid, he dreamed big dreams— then worked hard to make them come true. |

We were farm workers. Until I was 12, my family moved around every two or three months, following the harvest (丰收) of crops in California. That helped define me: I always work hard. |
It was December of 1972. I was 10, watching the final Apollo mission on a blackand-white TV. When I saw astronaut Gene Cernan walking on the Moon, I told myself, "I want to be an astronaut." |

NASA refused me not once, not twice, but eleven times! I finally got chosen the twelfth time. Five years later, I flew on my first mission to the International Space Station. Never give up! |
Floating (飘浮)! You're always floating. My favorite food was a burrito with scrambled eggs. We take tortillas to space because bread creates tiny pieces. It's really fun. |
|
As we passed over North America, I could see Canada, the US, Mexico, and other parts of Latin America. It surprised me that I couldn't tell where one country ended and the next started. Borders are human-made. From up there, we're just one. |
