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.

How did we get humans on the moon in 1969 and are still struggling to get the Starship rocket to launch properly? (self.nostupidquestions)

Blue Origin: “Here’s renders and a papier-mâchė model of what our lander will look like. It’s assembled together in lunar orbit, from an automated cargo ship, our own lander and another Orion.” Note that this isn’t what they won the option b proposal with.

Tell you what: Here's the mockup BO delivered to NASA: https://aviationweek.com/defense-space/space/nasa-evaluate-blue-origin-human-lunar-lander-hands

SpaceX: “Here’s renders of what our lander will look like.

Wow, renders! They even have renders of Starship on Mars, it must be true!

We have a full scale prototype out in Boca and we’re blowing it up to see if our math and simulations are right on how much pressure the tanks can take.

No they don't. Not of HLS, and also not of "Starship as needed for HLS". Musk's latest speech at SpaceX said the IFT-3 version of starship, that is now called "Starship 1", can only lift 40 tons to LEO. And that makes it incapable of doing Artemis, and thus incapable of being HLS. He promised "Starship 2" will lift the promised 100 tons to LEO, but that hasn't flown yet. So they don't even have a full-scale prototype, but they have scale-models that kinda-sort-look-like-it, and one of them even flew half a mission without a single gram of cargo.

It’ll require some modifications, such as larger landing legs and dedicated landing engines.”

Look, there's apparently a major gap in your knowledge. Starship+Superheavy is big cargo truck that can haul a load or cargo into orbit and come back. What NASA paid for is a trailer-RV that will let you camp out in death valley for a couple of months. And what you're saying is "Well, SpaceX has got an empty trailer and something to pull it, which is basically the same thing as a full house-on-wheels, because they look the same from the outside."

I don't know how to explain that a lunar lander is very much not the same thing as a rocket with an empty shell on top. SpaceX has the latter.
