这项由西北大学、芝加哥大学和中佛罗里达大学的研究人员进行的研究于本月早些时候发表在《科学进展》上，指出火星表面三分之一的区域有浅埋的水，但仍然太冷，不适合生命存在。 。
Mars, Earth's fourth-closest neighbor from the Sun, has long captured the attention of scientists and science fiction enthusiasts alike. With its characteristic red hue and rocky terrain, Mars has been a subject of fascination and a potential candidate for human colonization. However, rendering Mars habitable for humans poses a significant challenge due to its thin atmosphere, frigid temperatures, and lack of breathable air or liquid water on its surface.
火星是地球距离太阳第四近的邻居，长期以来一直吸引着科学家和科幻小说爱好者的关注。凭借其特有的红色调和岩石地形，火星一直是一个令人着迷的主题，也是人类殖民的潜在候选者。然而，由于火星大气稀薄、温度寒冷、表面缺乏可呼吸的空气或液态水，使火星适合人类居住面临着巨大的挑战。
Over the years, various proposals and methods have been put forth to terraform Mars, aiming to alter its environment and make it more hospitable to human life. One such approach involves releasing engineered dust particles into the Martian atmosphere to enhance the natural greenhouse effect and warm the planet. This method, proposed by researchers from Northwestern University, the University of Chicago, and the University of Central Florida, utilizes dust particles that are designed to efficiently trap heat and scatter sunlight to the surface.
多年来，人们提出了各种改造火星的建议和方法，旨在改变其环境，使其更适合人类生活。其中一种方法是将工程尘埃颗粒释放到火星大气中，以增强自然温室效应并使地球变暖。这种方法由西北大学、芝加哥大学和中佛罗里达大学的研究人员提出，利用灰尘颗粒来有效地捕获热量并将阳光散射到表面。
The study, published in Science Advances, highlights the potential of using dust particles that are engineered to be short rods, measuring approximately 9 micrometers in length and designed to effectively block thermal infrared and scatter sunlight to the Martian surface. These particles are engineered to enhance Mars's natural greenhouse effect and efficiently warm the planet, outperforming the best gases by more than 5 × 103 times. According to Samaneh Ansari, a graduate student at Northwestern University working in Professor Hooman Mohseni's group, these particles can be engineered to have optical effects that far exceed what is conventionally expected from such small particles.
这项发表在《科学进展》上的研究强调了使用尘埃颗粒的潜力，这些尘埃颗粒被设计成短棒，长度约为 9 微米，旨在有效阻挡热红外线并将阳光散射到火星表面。这些粒子经过精心设计，可以增强火星的自然温室效应，有效地使地球变暖，其性能比最好的气体高出 5 × 103 倍以上。西北大学胡曼·莫森尼教授团队的研究生萨马内赫·安萨里 (Samaneh Ansari) 表示，这些粒子可以被设计成具有远远超出传统上对此类小粒子预期的光学效应。
Calculations indicate that if these particles are released continuously into the Martian atmosphere, they could collectively raise the temperature by over 50 degrees Fahrenheit, with this warming effect becoming evident within months. To reverse the warming, the release of particles can be halted, and the effect would be reversed, stopping within a few years.
