Sustainability in Space 太空可持续发展

I guess we have talked enough about sustainability on our planet, but how about in space? Perhaps this is a topic that we may not think about when it comes to sustainability as space exploration is a relatively new aspect of humanity, which has just been introduced to us towards the end to the last century. However, as humans start to explore space and steadily become multi-planetary species, our preservation efforts of our collective future home will become more and more vital. So let's dive into this topic, shall we?

我想我们已经谈论了地球上的可持续发展，但太空中的可持续发展又如何呢？也许这是一个我们在可持续发展方面可能不会考虑的话题，因为太空探索是人类相对较新的方面，它是在上世纪末才被引入我们的。然而，随着人类开始探索太空并稳步成为多行星物种，我们对未来集体家园的保护工作将变得越来越重要。那么让我们深入探讨这个话题吧!

Space waste refers to the unused man-made object in space that is simply floating around. This can often be satellites, parts of space crafts, and missing equipments. Maybe you are still confused how floating parts can be harmful to space, well, here is the problem: collision between space debris and new launches can cause explosions, especially when they are not being located properly. This adds up to the cost of each launch, which can result in inefficient missions. Other issues such as shortening of a satellite's lifespan can also arise due to floating pieces like solar panels and other parts that may be functional to the satellites but are missing. Space debris start to appear primarily when satellites reach their lifespan and defunct in space. Space companies usually don't fetch them back as that would be costly and also requires extensive efforts. Guidelines have also been set to regulate space waste, however, because the structure and components of every nation's spacecrafts are made up of different types of materials, it is hard to classify the types of space waste produced, which makes it almost impossible to implement certain regulations and policies.

太空垃圾是指太空中未使用的人造物体，只是漂浮在周围。这通常可能是卫星、航天器的部件和丢失的设备。也许您仍然对漂浮部件如何对太空有害感到困惑，问题是：太空碎片和新发射的物体之间的碰撞可能会导致爆炸，特别是当它们没有正确定位时。这增加了每次发射的成本，可能导致任务效率低下。由于太阳能电池板等漂浮部件和其他可能对卫星有用但缺失的部件，也可能出现卫星寿命缩短等其他问题。空间碎片主要在卫星达到其使用寿命并在太空中失效时开始出现。航天公司通常不会将它们取回，因为这不仅成本高昂，而且需要大量努力。也制定了管理太空垃圾的指南，但由于各国航天器的结构和部件由不同类型的材料组成，因此很难对产生的太空垃圾类型进行分类，这使得某些具体实施几乎不可能法规和政策。

This issue is not new to the world, but more effective and straight-forward actions are required to make our environment a better one for the next generations to come. So what are your thoughts on resolving space waste?

这个问题对世界来说并不新鲜，但需要采取更有效、更直接的行动，为子孙后代创造更美好的环境。那么您对于解决太空浪费有什么想法呢？
