Do Peru's potatoes have the right stuff? 秘鲁的土豆能经受住考验吗？ That's the question scientists will be asking in Lima next month, when a selection of tubers will begin undergoing tests to determine whether they're fit to grow on Mars. 这是下个月科学家将要在秘鲁首都利马问的一个问题，届时，经过精心挑选的土豆块茎将接受测试，以确定它们能否在火星上种植。 NASA, the US space agency, is conducting the pioneering experiment together with Lima's International Potato Center (CIP). 美国航天局（NASA）将与利马国际马铃薯中心（CIP）联手，进行这一开创性实验。 They will cultivate a hundred selected varieties already subjected to rigorous evaluation in extreme, Mars-like conditions that could eventually pave the way to building a dome on the Red Planet for farming the vegetable. 他们将对100种精心挑选的、已在类火星极端环境下严格评估的品种进行培育，而这最终将为人们在这颗红色星球上建立蔬菜种植“大棚”铺平道路。 |
