2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious right or left wing sources will be removed at the mods discretion. We have an actively updated blocklist, which you can see here: https://lemmy.world/post/2246130 if you feel like any website is missing, contact the mods. Supporting links can be added in comments or posted seperately but not to the post body.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source.
Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners.
The auto mod will contact you if a link shortener is detected, please delete your post if they are right.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

Why would you wait to have something else ready if you think what you have is going to work?
All the physics modeling they did and live tests showed that the concrete should work.
When it looks like something should work, you test it. They had approval to test it after showing it should work.
These people are launching and landing rockets at a pace never done before, they know how to model these kind of things. Now obviously something went very wrong here, but it wasn't just a willy nilly choice.
You test the things that you think will work, otherwise you never know if they'll work.
While the concrete may not have been their final decision for Boca Chica, it doesn't mean it wasn't a possible solution for other location where a large quantity of potable water isn't available.
Edit: just further to possible other locations, the concrete if it worked, wouldn't allow the rapid turn around time they want as they'd need to set new concrete vs piped water ready to go. But for a launch location that maybe wouldn't need the rapid cadence, maybe it'd be perfect and cheaper if it'd work.
Because it might not work, and we're talking about millions of dollars worth of rocketry here, not a bottle rocket launched in your back yard.
Obviously not, or the pad wouldn't have blown up.
Which is why you implement backup/alternative systems.
LOL. Dude, they weren't even sure that the ROCKET wouldn't destroy the pad (edit: as in, the WHOLE launch pad including the tower). They're literally making the largest most advanced rocket ever. There are countless unknowns until you test it.
Exactly, which is why implementing backup systems or planning for catastrophic failure modes is a Really Good Idea.
lol
Are you an engineer?
I just find it hilarious that your trying to say people shouldn't test things all their tests and modelling says should work, because this OTHER thing, that's also never been tested at the same extreme levels, might work better, but you know, maybe not.
I'm done with this conversation before I feel more inclined to violate rule 1.
I'll take that as a no.
Standard for engineers is to have backup systems to your backup systems.
Especially for something as important as a rocket that will someday have astronauts on it.
This was cost cutting and rushing which is bullshit pushed by management, not engineers who know what they’re doing.
This is a TEST rocket program.
The goal of the program is to figure out what does and doesn't work.
There are numerous ~~zero~~ single failure points all over the ship currently as they figure things out.
Using the concrete was a way to test if they could set up a launch pad easier. ALL their tests and modeling proved it should work.
Tests and modeling aren't the end all be all though and sometimes things you don't or can't anticipate happen and then you remodel with the new info. This isn't a high school project, it's rocket science.
There was nothing bullshit about testing it out.
The goal of IFT1 was don't blow up the entire stage 0. They didn't blow up the entire stage 0. They learned the concrete doesn't work, but also hopefully they were able to learn WHY. And if they found a why that why may lead to it being attempted again in the future maybe even by someone else.
You’re not an engineer, are you?
No, I'm not an engineer (and that's an Ad Hominem fallacy). But for the love of god, SpaceX is a terrible company because they launched a rocket with INTENTIONALLY missing heat shield points to see what would happen (edit: all while knowing if certain heat shield tiles failed it would guarantee the complete destruction of the ship, that would obliterate any crew you're oh so concerned about in this test phase!), and even launched their rocket with wing flaps that they suspected would be destroyed by the hot plasma and had already made changes in future designs! God forbid they test a ablative concrete launch pad that survived all their real world tests and showed it should work in models.
You’ve just explained why we’re pissed at them and not even realized it.
And you've just explained how you have absolutely no understanding of how spacex functions and why and why it's a good thing.
This is how they land rockets on barges at sea and no one else can, or thought it was even possible.
