What will astronauts eat when a space trip takes years?

“Lots of fresh vegetables,” says Dr. Janet Williams, whose team have spent the last 10 years learning how to grow plants in a space station. And it’s a good thing that she has already started her work, because space gardening can be really hard.

As usual, astronaut George White looked into the closed plant room. He had planted Dr. Williams’s quick-growing seedlings none of the stems were showing. He opened the room to check and found the problem. The stems weren’t growing upward and the roots weren’t growing downward. On Earth, gravity (重力) helps a plant’s stems and in it, but roots (根) to find “up” and “down”. However, in the space station, there was almost no gravity.

Dr. Williams suggested a method: give the plants more light, as plants also use sunlight to find their way. And it worked. When the plants had more light, the stems turned up and the roots went down.

Now Dr. Williams was free to worry about the next problem: Would her baby plants live to flower? Can we grow food on a space journey?

Many plants died in the space station. Dr. Williams thought she knew why: the space plants were hungry for air. Plants live by taking up CO₂ from the air. Since a plant uses it up in the air around, the plant needs moving air to bring more CO₂ close to its surface! On Earth, the air is always moving. Gravity pulls down cold air, and warm air rises. And with these air movements, plants get enough CO₂.

Many earlier experiments (实验) with plants in space had used closed rooms. Dr. Williams tried a new greenhouse that had a fan (电扇) to keep the air move. The plants loved it. They flowered and even produced more seeds. Using Dr. Williams’s method, astronaut George completed the first seed-to-seed experiment in space, and moved one plant closer to a garden in space.

“And this,” says Dr. Williams, “is good news for long-term space travel.”

China has named the nation’s first Mars rover（火星车）ZhuRong. For all of us, Zhu Rong is a well-suited name.

In an ancient Chinese story, Zhu Rong had the face of a man and the body of an animal. H rode on two dragons. When he had a big fight with Gong Gong, the god of water, Zhu Rong won. But after the fight, the human world came into complete darkness. Then he brought fire from heaven（天国）to the world.

“Zhu Rong is regarded as the earliest god of fire in traditional Chinese culture,” a space official said. “The first Mars rover was named Zhu Rong. The name symbolizes（象征）light and hope for space exploration（探索）in our country, and means to guide humans to continue exploration.”

After leaving the earth last summer, Zhu Rong circled Mars for several months and landed on it in May. In recent years, our country has sent up the world’s first quanturn satellite（量子卫星）, and Chang’e-4 has made a soft landing on the moon. We have made great progress in space technology and will soon start building our own space station.
