如果有一个“时空胶囊”，能够向宇宙讲述人类文明的故事，它会装下什么？ 纪录片《星际信使：你不了解的中国科学故事》以“时空胶囊”的创意概念贯穿全片，将记录下的一个个令人惊叹的新时代中国科学故事存储其中，以面向宇宙的未来感叙事，描绘人类共同的家园，讲述我们如何用科技力量守护这颗蓝色星球。从青藏高原的洞穴考古到人工智能的飞速发展，从“深海勇士”号的探索到中国空间站遨游太空，从“人造太阳”的冰火共存到“人工合成淀粉”的创新突破，从照亮未来的“超级镜子”到承载希望的“生命方舟”，从“中国天眼”的脉冲星地图到解密衰老的“基因开关”……这些故事不仅展现了人类对未知的无尽探索，更揭示了我们在浩瀚宇宙中的独特位置与使命。这是一份关于人类发展、地球共生与生命探索的科学记录，也是一场跨越时空的文明对话，一封寄往宇宙的交流邀请函，向未来传递着人类的智慧与希望。

In this spellbinding series, Professor Brian Cox visits the most extreme locations on Earth to explain how the laws of physics carved natural wonders across the solar system.

When Neil Armstrong stepped onto the moon in 1969, America went down in popular history as the winner of the space race. But that history is bunk. The real pioneers of space exploration were the Soviet cosmonauts. This remarkable feature-length documentary combines rare and unseen archive footage with interviews with the surviving cosmonauts to tell the fascinating and at times terrifying story of how the Russians led us into the space age. A particular highlight is Alexei Leonov, the man who performed the first spacewalk, explaining how he found himself trapped outside his spacecraft 500 miles above the Earth. Scary stuff.

We think of ourselves as a global species, but in fact we can only comfortably survive on less than a quarter of the earth's surface. In To Boldly Go, doctor of extreme medicine Kevin Fong sets out to discover how we are able to conquer the other 75 per cent. In an eye-popping series of experiments, Dr Fong uses his own body to demonstrate how unsuited our biology is to much of the planet - and how we have had to develop the technology to let us survive there. （转自mvgroup论坛）

Dr Michael Mosley seeks to establish the truth about meat. Every year, humans raise and eat 65 billion animals - nine animals for every person on the globe. In this eye-opening documentary, Michael examines the impact that this is having on the planet and finds out what meat eco-friendly carnivores should be buying. Is it better to buy free-range organic or factory-farmed meat? The answers are far from obvious.

转基因技术，无疑是二十一世纪最具争议的科学问题之一。随着世界人口总数的不断增长，我们需要在未来的五十年里种植出双倍量的粮食，才能满足我们日益增长的需求。那么，转基因食品会是解决这一严峻的生存问题的办法么？转基因食品的确是提高食物产量和预防饥荒的重要武器，然而它又是未经检验的，甚至会引起环境灾难的危险科学。一位可持续养殖的拥护者吉米·多尔蒂，开始了他探秘转基因食品背后真相的旅程。从阿根廷传统大豆种植场，到乌干达拥有尖端技术的香蕉种植园，吉米的使命就是找出“转基因食品到底能否养活这个世界”的答案。 地平线系列纪录片是英国广播公司BBC制作的一档流行并且播放已久的科学纪录片，于1964年5月2日首播，到2013年为止已有49个系列超过1100集。本系列纪录片从历史、人文、宗教、地理、设计、艺术、生物、哲学、环保、伦理等多个方面，提供世界上最伟大科学家和哲学家一个可以交流他们看法和观点的平台，并将他们对世界的新看法引入到我们的日常知识中来的科教节目。

In light of the extinction crisis facing the Earth and using the dodo's story as a cautionary tale, this documentary looks at the different causes of species extinction and asks whether there is anything we can do to stop them.
