To confirm the finding, humanity would need to make yet another trip to Mars. "Getting there and acquiring the final evidence that this is indeed a lake will not be an easy task," scientists said. " It will require flying a robot there which is capable of drilling through 1. 5 kilometers [or about 1 mile] of ice, and this will certainly require some technological developments that at the moment are not available. "
Still, the research marks another chapter in the story of water on Mars, which stretches back billions of years ago, when the planet was still young. Back then, Mars was a watery world. The planet was surrounded by a warm, thick atmosphere. Fluffy clouds hung in the sky, and liquid water pooled on the surface, sloshing around in deep craters that sit empty today. Research suggests that Mars may have had enough water to coat a fifth of the planet.

答案
为了证实这一发现,人类将需要再次前往火星。“抵达火星,获得最终的证据证明这确实是一个湖泊并不是一件容易的事,”科学家说,“这就需要带一个可以钻探1.5千米(或大约1英里)厚的冰的机器人过去,目前我们的技术还达不到这个水平。” 尽管如此,这项研究还是翻开了火星上有水这个故事的新篇章,这个故事可以追溯到数十亿年前,当时这个星球还很年轻。那时候,火星是一个水世界。这个星球被温暖厚重的大气所包围。蓬松的云彩飘在天空中,液态水汇集在地面上,在今天空无一物的深坑中流动。研究表明,火星上的水可能曾经可以覆盖这个星球的五分之一。
