It’s not truly important to put a label on it, but if you insist:
It’s an ab initio failure to properly invoke the “appeal to authority” fallacy. Why? I’m not just vaguely citing NASA, I’m citing what NASA actually has explained.

See explanation. If Richard Dawkins says something, it’s not true just because he said it. But: “What makes it true is the preponderance of evidence for the theory.”
So, if you want to challenge the evidence NASA has brought to the table on this issue, the proper method is to introduce expert opinion that counters it.
It is relevant to consider the credentials of the authority in question, too. There’s substantially more reason to trust NASA than, for example, a YouTuber who “woke up” in 2014 and has a home-built science lab where he monitors “space weather” (as one ImgFlipper tried to do to me).
To address your example: There’s little reason to think Jesse Jackson is an expert on abortion laws or ethics. But the U.S. Supreme Court, for example? Different story. They’ve put out opinions that explain their constitutional reasoning and if you want to change the law on this, you cannot just dismiss those arguments out of hand.
It can also be thought of as an argument from ignorance. Or a massive shifting of the goalposts.
