General FE consensus is that anything having to do with going beyond the atmosphere of Earth is a hoax, because space travel itself is a lie. Wiki goes over this some, but that's the broad strokes of it. As for the planets and stars we see, I believe that's no precise agreement, even here. The two most common views are that they are in fact all out there and real, or that they're holes in some form of sky dome. The former is the more prevalent upon these forms though I would say, and is the one espoused in the wiki.
Some FE'ers seem to be saying that EVERYTHING that NASA say is a lie - a knowing fabrication. The size of that conspiracy is mind-blowing...it would have to have extended at least 400 years into the past (because sailors claimed to have used celestial navigation techniques that couldn't have worked in FET)...and would have to cover a dozen major governments, 450+ astronauts and cosmonauts, 400,000 people who worked on the moon shots at NASA and about a million other people who've worked on spacecraft since then. Astronomers would also have to be in on the conspiracy - so add another million or so people there...then all of the people who write software for GPS receivers, etc.
Others say that NASA staff are EXPECTING their results to show a curved earth and so when the images come back not showing that, they presume they've made an error and "correct" the image back to show a round earth...that's kinda insulting to a bunch of VERY smart people who'd spot the true facts in a heartbeat.
The latter are going to have a hard time with the mars rovers. Clearly, they are either on a large planet that isn't Earth - or NASA are faking it at enormous expense instead of just saying "Sorry - it's too hard to get rovers to Mars"...which would be a lot cheaper and easier for them.
I think it's sad.
I read this story today - about the insane lengths everyone went to in order to find a rock out in the Kyper belt to extend the New Horizons mission out by another couple of years using just the few ounces of fuel left in it's rocket tanks. A town in Pategonia going to amazing lengths to allow the NASA team to observe a blink in the brightness of a star lasting under a second so that it's speed could be accurately determined and so the space probe (already FAR past Pluto) can use those last drops of fuel productively. They shut down a freeway to get rid of light pollution - and when it looked like the wind would shake the telescopes and ruin this once-ever observation - they brought a bunch of semi-trailers and parked them around the telescopes to shield them from the wind.
This tiny rock will be (by FAR) the most distant object ever to have been explored by the works of mankind.
That's such a wonderful thing - it makes me proud of humanity that we crave knowledge to this degree - that we'll go to such lengths to see what's over the next hill.
https://www.nasa.gov/feature/nasa-s-new-horizons-team-strikes-gold-in-argentinaThe bleak, miserably limited world of the Flat Earthers, full of nonsense and misunderstandings is a horrible place by comparison. You almost feel that you're rescuing people from these horrors by opening up the true magnificence of the universe to them.
