Main priority to prevent accidents is to migrate away from this imperial system.

You can forget to carry a 1 in metric, too.

It won't save everything will will reduce at least two possibles routes of mistake (wrong unit, or imprecise conversion).

OP wrote "km miles", which would create an incident.

SpaceX uses metric system for that exact reason, because in the past, on Mars, accident happened because of imperial measures.

Increased launch cadence is an operational achievement, not an engineering one. And I'm not so sure that they actually decreased price to launch all that much. First of all, it's definitely not "several orders of magnitude", the best numbers quoted are maybe half price or so for a Falcon 9 compared to another contemporary rocket. And by my understanding, the US government at least is paying about as much for Falcon 9…

I was comparing to the achievements of 60 years ago when they put people on the moon :) They are working towards that in a sustainable manner.

So…not something they achieved?

This seems like a fairly disingenuous comment. SpaceX gets credit and rightly so because they have achieved things which no national space agency nor private company has ever done before, and done it faster and at a lower budget than anyone has done before. Every other national space agency and private company had both infinitely more money, time, and engineers than SpaceX did (when founded) yet they were making zero…

The whole world combined VS SpaceX has less mass to orbit.

Either whole nations are not interested in that much mass to orbit or they don't have the capability. Or financial means/incentive to compete against that commercial entity.

But they do and at least in China they start to work on reusable rockets and ULA is for sale because they don't have one.

Would be unpleasant if there was crew. Of course this thing is pretty far from human eating.

Would be unpleasant if there was crew. 19 people have died in the 391 crewed space missions humans have done so far. The risk of dying is very high. Starship is unlikely to change that, although the commoditization of space flight could have reduce the risk simply by making problems easier to spot because there's more flights.

I could imagine the risk going down to a few times air travel after 50+ years of operating a mature launch system.

Test code by running it. Test a rocket by launching it.

In production? I don't disagree that tests 'in production' are sometimes necessary (canary tests), but most of the quirks are often fixed by then. Honestly I thought they would be live testing fuel exchange in orbit by now. Seems pretty far from it sadly.

There was no real payload on this, so I'd argue it's closer to a QA environment than production.

It's true that other rocket companies are treating launches as production, but SpaceX has always been doing "hardware-rich" testing.

No, they successfully sent two to the Moon on Weds. https://www.cnn.com/2025/01/14/science/nasa-launch-firefly-i...

Looks like second stage broke up over Caribbean, videos of the debris (as seen from ground): https://x.com/deankolson87/status/1880026759133032662?t=HdHF... https://x.com/realcamtem/status/1880026604472266800 https://x.com/adavenport354/status/1880026262254809115 Moment of the breakup: https://www.instagram.com/reel/DE52_hVSeQz/

Does anyone know the timing of when the breakup actually occurred? I’m curious because I was on a flight to Puerto Rico from Florida at 3pm ET they diverted our flight. They didn’t really give us many details but said the “landing strips were closed”. Our friends on a slightly early flight diverted to ST Thomas. We were going to divert to a nearby airport in Puerto Rico (we were going to land in Aguadilla instead of…

Depending on the precise launch time (4:36/4:37 PM CST) "Ship exploded at ≈T+00:08:26": https://en.wikipedia.org/wiki/Starship_flight_test_7

Actually similar to how Twitter used to be. (Of course now it has other problems.)

What problems does it have now?

Integrity, mainly. Elon is not an honest person and he will use any power at his disposal arbitrarily to silence people he dislikes when he feels like it.

The most absurd example of all is the very recent case where Elon pretended to be a pro gamer and got caught. A streamer called Asmongold covered the topic on his stream, which triggered Elon to arbitrarily remove Asmongold's verified checkmark and remove his gaming badge. Considering the low stakes of this matter I find the actions ridiculous and don't trust Elon with having basically admin access to the platform at all.

I've also heard plenty of horror stories about the ruthless way the engineering in X is currently done, often carelessly breaking stuff. However I have to point out that the service is and has been far far more stable than the "haters" have predicted back when Elon took over and fired all those people.

Preliminary indication is that we had an oxygen/fuel leak in the cavity above the ship engine firewall that was large enough to build pressure in excess of the vent capacity. Apart from obviously double-checking for leaks, we will add fire suppression to that volume and probably increase vent area. Nothing so far suggests pushing next launch past next month. https://x.com/elonmusk/status/1880060983734858130

I'm not sure there's fire suppression effective enough for this type of leak (especially given rocket constraints)

just increased venting to keep any vapor concentrations of fuel and oxidiser below that capable of igniting, even simple baffling could suffice as the leaks may be trasitory and flowing out of blowoff valves, so possibly a known risk. Space x is also forgoeing much of the full system vibriatory tests, done on traditiinal 1 shot launches, and failure in presurised systems due to unknown resonance is common. Big question is did it just blow up, or did the automated abort, take it out, likely the latter or there would be a hold on the next launch.
