People are obsessed with Mars. But … why? Two confessed super-fans, Andy Weir, author of “The Martian,” and Stephen Petranek, author of “How We’ll Live on Mars,” share thoughts on why being Mars-mad is a reasonable state of mind.
自17世纪约翰内斯·开普勒借助火星阐释宇宙秩序以来，人们便对这颗红色星球产生了近乎痴迷的迷恋。随着火星上存在流动液态水的消息公布，这份痴迷似乎丝毫没有消退的迹象。在此，两位自称铁杆粉丝的人——《火星人》一书及同名电影的作者安迪·威尔，以及TED图书《我们将如何在火星上生活》的作者斯蒂芬·彼得拉内克——分享了他们对于”火星狂热”为何合情合理的看法。
火星，火星，火星。为何所有人都在谈论火星。威尔的电影无疑是火星成为时代焦点的原因之一。那就让我们把眼下这股热潮稍稍归咎于他吧。那么，他究竟为何如此在意？因为我们已知的关于火星的一切，实在令人叹为观止。”我从小就是太空和太空旅行的忠实粉丝，所以我不记得自己有哪一刻对火星不感兴趣。它有着无穷无尽的魅力，”他说，”举个例子：太阳系中最高的山峰是火星上的奥林帕斯山，高度是珠穆朗玛峰的三倍。但它同时也非常宽阔，山基面积大约相当于美国亚利桑那州。这意味着山体的实际坡度极为平缓，以至于火星本身的曲率对地形的影响，甚至比山坡的坡度还要显著。
