Does NASA reveal everything about its Mars exploration to the public?

It does not reveal all the alien spaceships it encounters, that is for sure.

I think NASA is very open and reveals pretty much everything. It wants to engage the public as much as possible for political and funding reasons.

They didn’t televise the two Martian patrol ships fly up to the Insight device and ask it for it’s interstellar driver’s license,

Hmm. Interesting, @flutherother. Just on general principles, I was going to say that I doubt that NASA ever reveals everything about anything, which is the same thing I would say about any person or institution in the world. I simply take for granted that there’s always something seen and something hidden, just as there is always light and shadow.

Actually, I’ll still say that, but I’ll call it an opinion, not a fact.

@Jeruba Some institutions are compulsively secretive even when there is no real need for it but I believe scientists and scientific institutions tend towards openness. There is as I said the need to get the public on board to support funding applications but apart from that scientists love nothing better than explaining what they find so fascinating about their work.

That said, it is certainly possible that an experiment might be carried out in secret but if there was no compelling reason for secrecy I think word would tend to get out. Just my opinion.

Well, I understand that NASA stands for Never A Straight Answer.

And, they still haven’t explained the Mars rock that appeared from nowhere

I think so. Like the Mars lander that had spaces in the tire treads that left markings in the soil that read “JPL” in Morse code.

Thought you might get a kick out of this: relevant
