The idea of turning Mars into a livable world for humans is a common element of science fiction. But could such an action be done in real life? 

将火星变成人类可以居住的世界的想法是科幻小说中的常见元素。但这样的行动在现实生活中能实现吗？ 

Scientists are now proposing a new method to warm up Earth's planetary neighbor. The idea involves putting engineered particles made of iron or aluminum into the atmosphere. The goal is to trap escaping heat and direct sunlight toward the Martian surface. 

科学家们现在提出了一种新的方法来加热地球的邻居星球火星。这个想法涉及将由铁或铝制成的工程颗粒放入大气层中。目标是捕获逸散的热量，并将阳光直接引向火星表面。 

The proposed idea would be to increase the natural greenhouse effect on Mars and raise its surface temperature by around 28 degrees Celsius over ten years. 

这一提议的想法是增加火星的自然温室效应，并在十年内将其表面温度提高约28摄氏度。 

Such a change alone would not make Mars livable for people. But the scientists who developed the idea see it as a possible first step. 

这种变化本身并不会让火星适合人类居住。但提出这一想法的科学家将其视为可能的第一步。 

Edwin Kite of the University of Chicago helped lead the study that appeared recently in the publication Science Advances. 

芝加哥大学的埃德温·凯特帮助领导了最近发表在《科学进展》上的这项研究。 

Kite described the process of terraforming – meaning to change a planet’s environment to be more like Earth. "For Mars, warming the planet is a necessary, but insufficient, first step. Previous concepts have focused on releasing greenhouse gases, but these require large amounts of resources that are scarce on Mars," he said.

凯特描述了地球化的过程——即改变一个行星的环境，使其更像地球。“对于火星来说，温暖这个星球是必要的，但还不够。之前的概念集中在释放温室气体上，但这些需要大量在火星上稀缺的资源，”他说。 

Kite added that climate modeling suggests the new idea of using engineered particles to warm Mars’ atmosphere could work better than previous ideas. Kite explained that the work i
