他与人合写了 1968 年电影《2001：太空漫游》的剧本，这是有史以来最有影响力的电影之一。克拉克是一位科幻小说作家，是太空旅行的狂热普及者，也是一位能力出众的未来学家。他为流行杂志写了很多书和许多文章。1961年，他获得了联合国教科文组织颁发的卡林加奖，以表彰他的科学普及。克拉克的科学和科幻作品为他赢得了“太空时代的先知”的绰号。他的科幻作品尤其为他赢得了许多雨果奖和星云奖，这些奖项以及庞大的读者群使他成为该类型的高耸人物之一。多年来，克拉克、罗伯特·海因莱因和艾萨克·阿西莫夫被称为科幻小说的“三巨头”。

克拉克是太空旅行的终生支持者。1934年，他还是个十几岁的少年，就加入了英国星际协会。1945年，他提出了一种使用地球静止轨道的卫星通信系统。他于1946年至1947年和1951年至1953年担任英国星际协会主席。

克拉克于1956年移民到锡兰（现在的斯里兰卡），追求他对水肺潜水的兴趣。那一年，他在亭可马里发现了古老的科内斯瓦拉姆神庙的水下遗址。克拉克在 1980 年代增加了他的知名度，担任 Arthur C. Clarke 的神秘世界等电视节目的主持人。他一直住在斯里兰卡，直到他去世。

克拉克于1989年被任命为大英帝国司令勋章（CBE），以表彰他“为英国在斯里兰卡的文化利益服务”。他于 1998 年被封为爵士，并于 2005 年被授予斯里兰卡最高公民荣誉 Sri Lankabhimanya。

Sir Arthur Charles Clarke CBE FRAS (16 December 1917 – 19 March 2008) was an English science-fiction writer, science writer, futurist, inventor, undersea explorer, and television series host.

He co-wrote the screenplay for the 1968 film 2001: A Space Odyssey, one of the most influential films of all time. Clarke was a science fiction writer, an avid populariser of space travel, and a futurist of a distinguished ability. He wrote many books and many essays for popular magazines. In 1961, he received the Kalinga Prize, a UNESCO award for popularising science. Clarke's science and science-fiction writings earned him the moniker "Prophet of the Space Age". His science-fiction writings in particular earned him a number of Hugo and Nebula awards, which along with a large readership, made him one of the towering figures of the genre. For many years Clarke, Robert Heinlein, and Isaac Asimov were known as the "Big Three" of science fiction.

Clarke was a lifelong proponent of space travel. In 1934, while still a teenager, he joined the British Interplanetary Society. In 1945, he proposed a satellite communication system using geostationary orbits. He was the chairman of the British Interplanetary Society from 1946–1947 and again in 1951–1953.

Clarke emigrated to Ceylon (now Sri Lanka) in 1956, to pursue his interest in scuba diving. That year, he discovered the underwater ruins of the ancient Koneswaram Temple in Trincomalee. Clarke augmented his popularity in the 1980s, as the host of television shows such as Arthur C. Clarke's Mysterious World. He lived in Sri Lanka until his death.

Clarke was appointed Commander of the Order of the British Empire (CBE) in 1989 "for services to British cultural interests in Sri Lanka". He was knighted in 1998 and was awarded Sri Lanka's highest civil honour, Sri Lankabhimanya, in 2005.
