Possible version:

It's scary but beautiful-Martian-red dirt dotted with unknown plants, chocolate-brown mountain ranges and a sky that makes Martian sky look like the glow of a flame. Without special glasses, I couldn’t see much because the light is too bright. Besides, it must be too hot in the day and too cold in the evening so that I should wear a kind of coat to live a normal life there.

1. So great was the distance from Earth that it would need to travel for almost six years to reach its destination.
[句式分析] 这是一个倒装句。在so/such... that...结构中, so/such...置于句首时 ,主句采用部分倒装, that引导的从句不倒装。
[尝试翻译] 从地球到土星的距离是如此之远,以至于它将需要航行近6年才能到达目的地。

2. No wonder so many people took to social media to bid it goodbye, saying, “Farewell, dear Cassini! We shall never forget you!”
[句式分析] 语境中 No wonder 的完整形式为 “ It’s no wonder that-clause ”, 意为“难怪......”,其中的从句为主语从句而且后置。...saying... 为现在分词在句子中充当伴随状语。
[尝试翻译] 难怪这么多人在社交媒体上跟它说再见,说:再见,亲爱的卡西尼!我们永远不会忘记你!
