@UnwantedBlog You make crummy statements about a country I presume you've never visited, and won't take any contrary view from someone who lives there.

@Discjirm You're pretending to not understand the basic points being made in order to stretch out a pointless meandering "debate" with no purpose. Muted.

"We could have had the stars" is one of the more depressing realizations a reasonably intelligent person can have. Even Britain could have a thriving interplanetary civilization *right* *now* if they spent their tax money more wisely.
Peter Hague@peterrhague

I keep hearing people tell me how expensive space is. How its such a frivolous waste. Its utter nonsense. SLS/Orion is basically the most expensive rocket currently flying, and even using that as a yardstick, the UK government throws money away at a far larger scale. Just look

@UnwantedBlog How do you think I'm debating dishonestly? Just because someone disagrees with you, does not mean that they are automatically a leftie. You love space. I love space. There is much commonality between us.

@Discjirm Ah, I see what's going on here. Took me a minute, but I'm still burdened with the initial assumption that people debate honestly.

@UnwantedBlog None, none, and none. Why are those prerequisites for a nation with a vigorous sense of itself, a pride in its people and history? I want more space exploration, both robotic and crewed. But why does every country needs an independent crewed launch capability?

@Discjirm What *manned* spacecraft do you have? What manned spacecraft does the UK have in development? Not as a minor partner, but as a vibrant, thriving nation with a vigorous sense of itself, with pride in its people and history, and a fervent desire to *expand?*

@MikeFuryTech @MSvanderWalt71 @terrikibiriti Some of these 'people' are bots. Some are trolls. Some are people who think that going against the consensus makes them intelligent; that they know the 'truth' whereas the sheeple don't. Some are just cosmically stupid.

@UnwantedBlog We don't, because as a country we had other priorities. Not having good launch sites was an issue. We do have a fairly healthy space industry though. 'Space' is not just about rockets. Rockets are just the trucks; the payloads matter. Without payloads, rockets are pointless.

@Discjirm I know you don't have doodly-shit for a space program, when by all rights y'all should've set up a colonial administration on Ganymede by now.

@TBrit90 As an aside, NASA funding was reducing from 1966, well before Apollo 11. The idea of an expanded AAP program was dead well before the landing. Why? In the entirety of the program, only one opinion poll had a majority of the American public think the expense was worth it.

@UnwantedBlog I do wonder how much you actually know about Britain, and where you're getting your information.

@Discjirm Yes, it is. For Britain to have the sort of interplanetary civilization is could and SHOULD have, it needs to unload the treasonous fools that have hamstrung it and shackled it to hordes of cultural and financial drains.

@Discjirm Step one: get rid of your current government, replace it with one that actually gives a rats ass about Britain and its people.

@arthistorynews @lionelbarber I don't think Trump's a Russian asset. I think he's someone who looks at Putin and sees a leader he likes. Strong, immovable, rich. And as Trump is weak, he gravitates towards things he thinks Putin would like. Trump doesn't see Putin's many negative points as negatives.

@Discjirm @terrikibiriti I will believe it when I see it, period. I know how much the past administration messed with evidence. I also know the moon race make weird people do weird things. To me it;s facts and figures...so I will wait and when I see it, I will bow and applaud!

@MSvanderWalt71 @terrikibiriti There is plenty of evidence. The US was in a race with the USSR, which spent billions on their own program. Why did the USSR - and no country to this day - deny that the USA landed man on the Moon? Because they know the USA did.

@MSvanderWalt71 @terrikibiriti There's no need to lay false evidence that man went to the Moon, as the real evidence remains there to this day. Any regular person with regular intelligence knows this.

Its all the nonsense they have to tell, to artificially create or script, to create a spectacle or an interest. Nobody has landed on the moon before. Perhaps when they land, they will have carte blanche to create the fake traces or proof that the US was there before. We, the regular people just have to decide for ourselves what we believe and don't believe.

@richeric4you @terrikibiriti The short duration was planned and understandable, though. Virtually everything they were doing was new, so the unknowns and risks with equipment were massive. Risks reduced with later missions, so durations increased. IMV the same thing will happen with Artemis landings.

@terrikibiriti It was the first one but actually the least productive, they missed the targeted landing site by miles and only spent about 2 hours on the surface and didn’t do much while they were there.

So wait there have been 6 moon landings in history? Why is Apollo 11 the only focus ?????

@AeroBigMike @megagoose11 IMV (as a non-American, so my vote doesn't count): America needs a heavy-lift capability. Indeed, it needs two systems for redundancy. The SLS mess should continue until such time the capability that replaces it is there. It is not, yet. Otherwise, China will get that capability

@megagoose11 I mean that’s how people responded to SLS. They moved the goalposts when SLS did what they said it never would. Note I was never in the camp that starship never would reach orbit- I knew it eventually would. It just hasn’t *yet* (objectively true).

@TechGeekATX @C_S_Skeptic So we have to ask ourselves why SpaceX are having so many problems at this late stage of development, where NASA could manage it in the 1960s, and ULA and Blue manage it with Vulcan and NG (though not without some issues for the former).

Meanwhile, at SpaceX. The FOURTH incident on the ground since IFT-11. This time, one of those totally proven and perfectly engineered Raptor 3 engines.

@TechGeekATX @C_S_Skeptic Indeed there were. But: *) The tech was much newer then, and there was much less knowledge of spaceflight, rocketry and computing. *) NASA did not lose a single Saturn I, IB or V. 32 rocket launches, all successes aside from a partial failure of Apollo 6.

@jo67260134 @carternixongr @unix_byte I fins the OP quite funny, as something that is being sold as brilliant (and SpaceX is brilliant) is actually - if accurately described - far behind what is standard in the industry. Whether that 'standard' is actually needed is perhaps an interesting question.

@carternixongr @unix_byte One of the Shuttle computers ran on a different software, the BFS or backup flight software and was not part of the "voting system".

Understanding Linux: The Kernel Perspective
SpaceX uses Linux in Dragon spacecraft with flight software written in C++. The Dragon and Falcon 9 flight systems use triple-redundant computer architectures based on commodity x86-class processors (rather than specialised radiation-hardened chips traditionally used in spacecraft, which lag behind in raw compute power). Three independent processors execute identical code in parallel and compare results; this voting-based design enables robust operation in the presence of hardware or software faults. x.com/elonmusk/statu…
