For those of you who like dubstep, start the following video first https://www.youtube.com/watch?v=t2eBMuL0C2o then 3 seconds later start to watch the (muted) SpaceX video from OP's post and thank me later. ;-) Especially the catch is awesome!

I think it's a cool achievement, but for some perspective NASA first did a vertical rocket ship landing without chopsticks decades ago. And the whole point of this thing was to do that on the moon, which is never going to happen at this rate.

Just makes it more humiliating for SpaceX competitors. ESA, China, ULA all playing catchup to NASA tech from decades ago. Why didn't they commercialize it?

Did Apple invent the touchscreen or the cell phone or high dpi displays?

Starship is the only part of Artemis that is actually working. In any case, a reusable rocket architecture is way ahead of the Apollo model, not a regression.

None of Artemis is working. Including Starship. (If Starship is working so is Orion.)

Sorry by working I meant more along the lines of “on track, on budget, meeting expectations” etc.

SpaceX just posted this video of the last test. It's one of the most inspiring things I've ever seen. https://www.youtube.com/watch?v=hI9HQfCAw64

Another rough take with some orchestra music from Stellaris, of all things. Start the SpaceX video and 'Towards Utopia' at around the 2:21 mark https://youtu.be/887f76RXvdE?t=141

> go again the same day. That seems like a stretch. What is the actual turnaround time for Starship? fwiw the Shuttle had a lot of lofty promises of reusability that were technically true as long as you didn't consider how long the turnaround time was.

Some of SpaceX's first stages are getting close to the individual Shuttles' launch counts, with substantially less turnaround time and cost than Shuttle ever had. Starship has work to do, but it's hard to argue they're not at least on the right path.

Also, less cost in life.

Not into space things and while this is cool i wonder what the great significance of this is? I see lots signaling how great this is and it's lost on me.

Honestly of very little significance to the typical individual. It isn't going to pay my bills or provide for my kids. It does nothing for people suffering war and genocide. Nothing for poverty, access to health care and education. Nothing for the biggest threats facing our civilization. It is still a remarkable technical achievement and I think the people who have designed and built these systems deserve some celebr…

Your posts reminds me of the building of the first transcontinental railroad. It had many fits and starts, and people thought it would take decades to pay off.

But just as soon as it was completed, it changed everything overnight.

This is what Musk is doing.

> because losing control of a Starship in low earth orbit would be catastrophic Why? Remote detonation wouldn't work in that case?

Remote termination is something they can do in the early boost phase, when there is a defined hazard zone over a depopulated patch of ocean. It doesn't cause the rocket to disappear; its effect is to disable the engines, end uncontrolled acceleration, and break the booster apart into small pieces—all of which will still fall to the ground (ocean) as debris. If you did this to a Starship in orbit, you'd likely have la…

"...all of which will still fall to the ground (ocean) as debris..." After it's been flying in orbit for awhile, where it could in theory hit something else.

As you say, the other part of it--and probably more important--is that if it's turned into orbiting pieces, there's no control over where it lands. Some of it could easily land on the ground rather than the ocean, who knows where. That of course has happened with other satellites and their final stage rockets in the past (notably by the Chinese), but Starship is bigger, and therefore the pieces that hit the ground could be bigger. By launching it sub-orbital for now, and turning off the engines so it lands in the middle of the Indian Ocean, the risks of both orbital debris and unknown ground landing points are avoided.

Detonation in orbit would cause garbage in orbit that could destroy many satellites. It is absolutely not permitted.

That makes a lot of sense.

Space based technology has massive impact on every day life. From GPS to weather prediction to communications, space infrastructure is critical to modern life.

> None of that listed technology comes from building reusable rockets.

Lower launch costs are a force multiplier for all of those technologies and more.

It sounds like your issue is more with capitalism than space...

But lower launch costs decrease the capital needed to particpate is space, so you point still doesn't make sense.

> Pretending that everyone is going to be better off because of this space dream delusion doesn’t really answer my question.

Everyone is already better off because of the soace dream. You don't seem to actually want an answer to your question.
