What dome? I measured the rover's distance when it was over 300,000 km away from Earth.

Re: Mars Perseverance Landing!
But did it film the "polka dots" of space on the way there and will there be video?

[link to www.youtube.com (secure)]
 Quoting: Chuckles


I'm not saying anything you can see through your telescope or even this landing is bullshit... but Don Petit is the worst improv actor I have ever seen

In the above video astronauts say:

1 - Space is black and there are no stars to be seen anywhere from Earth to the moon.

2 - There are so many stars and 'its cool because you can see them in the daytime.'

3 - It's really black but there are also all these polka dots.

4 - 1000 times more stars than on a mountain at night in Colorado and they don't twinkle.

5 - You can see the magellenic clouds along with the stars.

6 - You can't see stars in the daytime in leo.


It seems the experience of the stars for the astronauts would bear factual similarities if not the universal reverence and astonishment we are accustomed to from the moonless mountain experience.

I'm not saying space is a lie... but some of the astronauts are...
 Quoting: Chuckles

He's awkward and a nerd but that doesn't make him a liar. This has nothing to do with this thread and I really don't appreciate the attempted derailing. The divergent descriptions from the astronauts has to do with whether or not your eyes are dark adapted. That's what it really comes down to. If you are on the daytime side of the planet in orbit generally speaking there will be too many bright things shining in your eyes to allow you to properly dark adapt and see the stars. If you make a deliberate effort to block out all stray light sources, then yes you can dark adapt and see the stars.
 Quoting: Astromut



Apologies. You were fielding other questions with responses so I thought I'd ask. I'll take it to the other thread.

Your explanations are a little thin since it seems if one was in space one would take the time to 'dark adapt' ones eyes to see stars 1000 more numerous than a Colorado mountain top that do not twinkle. They dress in gorilla suits on the ISS, I think they have time to look at... space. Also astronauts clearly differ on whether stars can be seen in the daytime. ...or at all. ;)

I'll be over there.

 Quoting: Chuckles

They do, but most of them do it while on the night side of earth, or in the Apollo days, by using an eye patch. Apollo navigated to and from the moon using the stars and a sextant, but that was not the main focus of the mission. I tried to explain to you why the accounts differ, it's because it depends on whether they make the deliberate effort to do it during the day. Not all of them will, some of them are test pilots who don't care as much about amateur feats of astronomy.

Re: Mars Perseverance Landing!
since any radio transmission takes several minutes to come from there and more minutes to send to there, and the entry in atmosphere hampers any comm and the time between its end and land is a few minutes.. the landing was 100% automatic, blind to command center huh?
 Quoting: sunwatcher


Yes. Everything was automated and by the time we heard the first reports from the spacecraft that it was hitting the atmosphere it had already been on the surface for a period of about 4 minutes.

I'd like to see the video footage of the Mars helicopter trials that were done inside the extra large vacuum chamber at NASA's Plum Brook Station near Sandusky, Ohio. You ever been in it? It's like 110 feet tall inside, and you could fit a small cottage in there too.

I wonder how long it will take to release that or any similar type of training etc.

Before Covid, NASA would hold an Open House event once a decade at different facilities. Now, they wouldn't let you go everywhere, but they let the public come to see some amazing stuff, and all the researchers were the tour guides, except for security.
