Welcome to the News community!
Rules:
1. Be civil
Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.
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. Clickbait titles may be removed.
Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.
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, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.
7. No duplicate posts.
If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. 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 or news aggregators.
All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link. Newswire services such as AP, Reuters, or AFP, are frequently republished and may be shared from other credible sources.
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.

I wonder what the simulation showed was going to happen compared to the actual flight. Would give you a real metric of progress.
If the simulation showed a problem, they could have fixed it before launch. I'm guessing they don't have a enough data to make a super high fidelity integrated model for all phases of fight, so they'd break down the sections individually. But integration always brings extra challenges.
So they don't have a physicist on staff? Or several? We have known the math for rocket science for some time. What data is it they need? When even NASA in the sixties has simulators.
I'm sure they have tons. But we don't know the full thermo areo dynamics at hypersonic speeds and complex geometries, especially their effect on unconventional control surfaces across huge temperature and speed ranges. Some military companies have even bought flights on electron to get high altitude hypersonic velocity data on how the air behaves in that regime.
So rocket science...the thing the world has been doing since the end of WWII. Weird how other rockets don't have this problem....
You know of any other companies doing a belly flop maneuver? Or a reusable first stage with hot staging?
How reusable? NASA had recoverable boosters How does math and physics change based on goals?
NASA has never used hot staging.
I repeat math or physics changed?
No, the constants and dynamics in that flight regime are just not well understood.
So you are telling me PhD physicists don't know?
Yeah, broad strokes, but not super high fidelity stuff.
lmao people act like they can't comprehend that we haven't solved all physics yet
Yeah it's super easy that rocket science. Just plug some numbers into a simulation and off you go. It's not exactly brain surgery.
Tell that to Robert Goddard
