厉害了-科学家在南极温室首次收获蔬菜

Scientists in Antarctica have harvested their first crop of vegetables grown without earth, daylight or pesticides as part of a project designed to help astronauts cultivate fresh food on other planets.

作为旨在帮助宇航员在其他星球上培育新鲜食物的项目的一部分，南极科学家们已经首次收获了他们的不含土，日光或杀虫剂的蔬菜。

Researchers at Germany’s Neumayer Station III say they’ve picked 3.6 kilograms (8 pounds) of salad greens, 18 cucumbers and 70 radishes grown inside a high-tech greenhouse as temperatures outside dropped below -20 degrees Celsius (-4 Fahrenheit).

德国Neumayer Station III的研究人员表示，由于外界气温低于零下20摄氏度（-4华氏度），他们已经在高科技温室内种植了3.6公斤（8磅）沙拉青菜，18棵黄瓜和70棵萝卜。

The German Aerospace Center DLR, which coordinates the project, said Thursday that by May scientists hope to harvest 4-5 kilograms of fruit and vegetables a week.

协调该项目的德国航空航天中心周四表示，5月份科学家希望每周收获4-5公斤水果和蔬菜。

While NASA has successfully grown greens on the International Space Station, DLR’s Daniel Schubert says the Antarctic project aims to produce a wider range of vegetables that might one day be grown on Mars or the Moon.

虽然美国国家航空航天局已成功在国际空间站种植绿色植物，但德国农业研究中心的丹尼尔舒伯特说，南极项目的目标是生产种类更多的蔬菜，有一天可能会在火星或月球上种植。
