Based on the provided story, the evaluation of its Tragedy Degree and Comedy Degree is as follows:

- Tragedy Degree: The story outlines a series of challenges and setbacks humanity faces under President Lydia Hargrove's leadership. However, while these are significant and emotionally impactful, it does not evoke a very profound sense of tragedy. The tone remains hopeful and focused on solutions, mitigating the overall tragic impact. Therefore, I would rate the Tragedy Degree as moderate.

- Comedy Degree: The story contains almost no comedic elements. It's primarily serious and focused on problem-solving, governance, and survival in the cosmos. There are no light-hearted moments or humorous undertones, let alone a happy or delightful ending. Thus, the Comedy Degree is very low.

Considering this, the scores are:

```json
{
  "TragedyDegree": 5,
  "ComedyDegree": 1
}
```
