No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

So I've heard and seen the newest launch, and I thought for a private firm it seemed cool they were able to do it on their own, but I'm scratching my head that people are gushing about this as some hail mary.

I get the engineering required is staggering when it comes to these rocket tests, but NASA and other big space agencies have already done rocket tests and exploring bits of the moon which still astounds me to this day.

Is it because it's not a multi billion government institution? When I tell colleagues about NASA doing stuff like this yeaaaars ago they're like "Yea yea but this is different it's crazy bro"

Can anyone help me understand? Any SpaceX or Tesla fans here?

no rocket as powerful as this one.

So I'm confused on this because people still seem to be using Starships's old estimates of 100 tons to LEO orbit, which the SLS can put 145 tons to LEO.

Then 6 months ago Musk got on stage and updated the specs to Say that Starships's current design can only do 40-50 tons.

This feels awfully familiar for anyone that's seen early Tesla specs/presentations/promises and I can't help but wonder as to the validity of everyone saying SpaceX is mostly insulated from Musk's "influence."

To be very honest even if Starship is able to only lift 50 tons, which I'm sure they'll be able to hit 100/150 tons eventually. The huge difference in cost would easily cover the extra times Starship would have to fly, compared to SLS. Considering each flight of a SLS will be around 4 billion dollars.

I think they mean the "superheavy" (somehow a more stupid name than starship) booster rocket is the most powerful. I'm pretty sure by thrust metrics it is. It's just that the superheavy-starship system can't put much up in LEO because the starship is huge and heavy on its own.

If you put an expendable second stage on top of the superheavy booster instead of a starship it could put a lot more up to LEO.
