Scientists are planning the 2030 trip to Mars. It will take astronauts twelve months on the way and eighteen months living on the Red Planet. As well as building a spaceship and creating space stations, scientists must answer another question: what are the astronauts going to eat while they are away?
In 1961, Yuri Gagarin, the first person in space, ate food in tubes (软管). The next astronauts from the US had dried food mixed with water. Today, astronauts take ready-made meals with them. However, the meals will last for only about two years.
Maya Cooper, a researcher from the US, thinks she might have the answer. She studies how to grow plants in some special liquid (液体). And they grow surprisingly well. Maya's idea is for the astronauts to have a greenhouse on Mars. In the greenhouse, they can grow some kinds of plants. They could then prepare their meals with these and other food from the earth. This will help them get enough nutrients (营养物) to stay healthy. In this way, astronauts will be able to live on fruits and vegetables without meat products for the long trip.
Maya also works on menus for the astronauts. She has suggested more than a hundred different dishes, including egg soup and tomato salad. There is even pizza and chips on the menu so that the astronauts won't miss home too much. It is very important to make the Mars trip a success because the astronauts will do some valuable research on Mars. However, people need to solve food problem firstly.
