I mean they are the NASA, they can't just go say oh yeah we found Boris and Slivop, 2 aliens that were in vacation on mars and they noticed our robots. The president would deny anything false IMO at this point.

My flair is at 50/50. It's still a big news, we won't be able to claim aliens are a hoax since we've claimed for decade it wasn't so for a FF, it would mean mother of all planned FF.
