如果将来火星上的宇航员要活下来,就需要具备园艺技能。一个英国人领导的科研组计划在这颗红色星球上种生菜,希望这个计划会对将来建造人类地外栖息地的食物供应提供帮助。如果这个计划被接受,作为2025年在太空建造人类居住地的火星一号任务的一部分,生菜就可能最早于2018年被送上这颗条件恶劣的星球。火星上的夜间温度下降到零下90摄氏度,巨大沙尘暴会在几周内席卷整个火星,风速可达每
If future astronauts on Mars are to survive, they need gardening skills. An English-led research group plans to plant lettuces on this red planet, hoping the program will help to build a future food supply for humans outside the habitat.

Night temperatures on Mars dropped to minus 90 degrees Celsius, a huge sandstorm will swept the entire planet in a few weeks, the wind speed up to
