The weather of Antarctica(南极洲)is cold, cloudy with heavy snow. Most parts of it are covered with ice sea for 10 months. Though it is dry and seldom rains, scientists in Antarctica have gotten their first crop of vegetables that they grew without earth. As one part of a plan, it will help astronauts to study fresh food about other planets. If the plan is successful, people will have some space to plant vegetables and fruit.
Researchers at Germany's Neumayer Station III say they have planted 3.6 kilograms (about 8pounds) of salad green vegetables, including 18 cucumbers and 70 carrots in a high technology greenhouse(温室)，while the temperatures outside dropped below -200C. In this way, they can eat fresh vegetables in time.
The German Aerospace(航天航空) Center DLR, Daniel Dchubert, which was the leader of the plan, said on Thursday," Scientists hope to get 4 to 5 kilograms of fruit and vegetables a week in May.Maybe the plan can turn into reality."
While NASA has successful grown green plants on the International Space Station, DLR's Daniel Dchubert says the Antarctic plan decides to produce a wider range of vegetables, such as tomatoes, onions and so on. People might grow them on the Mars or the Moon one day.
We know people depend onagriculturesince the beginning of human history.
Without agriculture, people can't live for many years. At the same time, the development of agriculture needed some conditions, including environment, temperature, weather and so on. The technology develops quickly. People will plant the vegetables on the Mars sooner or later.
