关于此课程： 在这个免费的课程里学习目前的太阳系探索背后的科学。用物理、化学、生物和地理的法则去理解关于火星的最新的新闻，理解外太阳系，思考太阳系外的行星，寻找附近环境以及更远区域的可居住性。这个课程普遍在本科级别的数学和物理知识上讲授，但是大多数的概念和课程并不需要这些知识就能理解。小测和期末考试会考察你是否能对学习过的材料进行批判性思考，而不是简单的记忆事实性的知识。这个课程应该有些难度，但会很有收获。

Almost wish I could forget everything I just learned so I could take it again. Fantastic course.
Absolutely fantastic; stunned at the detail and complexity in which the material is covered with. The Instructor is very engaging and he has a genuine passion for this topic. The material is challenging but manageable. Definitely will recommend.
Great course, nicely taught and regularly updated. It taught me a lot.
This is by far, the best course I've ever taken! Space is the future! If you have an interest in space or know someone that does....I HIGHLY RECOMMEND taking this course. After you've successfully completed this course....you'll feel greatly rewarded!!!
