Starship is not a drop-in replacement for SLS. But it sure casts a long shadow on the entire SLS project.
Difficult to say relative to current Artemis timelines, which have to date been mainly delayed by Orion. They're currently looking on schedule to perform an orbital propellant transfer in 2026. That likely means a commercial launch before the end of next year, which is crazy.
How that relates to HLS is up in the air, and probably will be until the end of next year.
Starship is trying to do the hardest thing in the history of space flight. And of course its not on schedule, its schedule was always insane.
The way of approching things as 'is X on schedule' is a fundamentally false way of approching the problem. The question is who makes the schedules and why. Who decides the budget and why. Who planes for the architecture and why.
Just thrwing around and accusing different groups about who is 'delayed' is kind of counter-productive.
The fact is, the schedule is something Trump made up to sound cool in his first term, and has since been revised for multible reasons. And the demand for a lander was equally rushed. So the schedule is mostly just whatever politics at the moment wants to project.
Of course that was always wishful thinking. I'm sure SpaceX has their "real" schedule somewhere, and maybe NASA has one too (at least from what I've heard, it is likely they have an unofficial idea of it somewhere).
Now do Orion and ML2.
Artemis is behind schedule. Nobody debates that. Currently, the bottleneck is with Orion. SpaceX just massively de-risked the Starship platform with IFT-11. If IFT-12 validates Block 3, we should wait until the end of 2026 before trying to revëvaluate.
Building new things is genuinely hard.
But I have seen some serious, albeit delayed, successes.
It's not difficult to say. They are behind schedule and everyone, not just Duffy, is talking about it and have been for awhile.
I don't care - beyond how getting to the moon will help future space exploration - and risk is high when developing new tech, but I also don't care about SpaceX. It's very possible Starship won't work out; that's risk and I'm sure SpaceX and NASA people understand that. Why must people on HN defend SpaceX at every turn, like a PR agency. Does anyone point out a genuine, significant, negative about Starship? Why might it not work? What are the risks?
I think more competition is great and hope they reopen the contract. Private industry competing on what is now prosaic space technology, such as orbit and even the moon, is great. Let NASA do the cutting edge stuff like flying to Europa or looking back to the beginning of time or investigating climate change. (Notice that private industry still can't land on the moon reliably - 56 years after NASA demonstrated it.)
While on the contrary Boieng and friends try to use old tech they have in their archive to slap togetehr a minimal viable product to meet the requirment.
But the contract structure changes is not about giving contract to SpaceX only. Its about developing a space industry. And this has worked extremely well. Commercial cargo resulted in Falcon 9, Antares rockets. Antares team is now working with the Firefly startup for a next generation rocket. Clearly not as successful as Falcon, but without Falcon on the market it might have delivered differently.
It also produce Cargo Dragon and Cygnus. Both have seen a lot of further development since then and have all kinds of uses.
You can also look at CLIPS for moon landers, where some companies at small budgets have managed to build landers. And even those that weren't successful, training a lot of people on deep space probes.
If you comapre the explosion of the space industry since Commercial Cargo to the stgantion in the Shuttle/Constellation area you will see why many space fans are so in favor of the new model. And the amazing thing is, that a tiny fraction of the money was spent on the non-Shuttle/Constellation/SLS part.
In fact, I did the math and the total spend on just development of Constellation/SLS/Orion is going toward 200 billion $ over the last 25 years. And that is without actually delivering anything meaningful.
In comparison the complete development budget of Commercial Cargo was a few billion $ at most, and it has revolutionized the US space industry. The complete spend on all Commerical Cargo, Commercial Crew and Lunar development more like 20 billion $. And the impact is just hilariously larger.
Seems fairly obious what the way forward is, its just politically not feasable. As long as 50% of NASA discretionary budget is spent on ISS and Shuttle-derived stuff that will never be forward looking, you are playing the game with a hand tied behind your back and cement shoes.
IOW, it doesn't matter what SpaceX or the others are doing, SpaceX is the 'right kind of people' to them.
They aren't delivering, so maybe not. People on HN state the SpaceX talking points like they are reality. It's an Internet mob; there is no room for any serious examination of the issue.
How do you square that with "not delivering"? I don't doubt that China could surpass them in the next 5 years, but nobody else is realistically close to doing so.
And those comments are usually not long or detailed. Almost everybody that actually engadges in the discussion doesn't seem to defend that position.
Sorry that complex government contracts valued at 100s of billions of $ can't be discussed in snarky one-liners and throwing around random judgments based on nothing. You seem like somebody that should be on tiktok, not HN.
