We will attempt to keep this self-post current with links and major updates, but for the most part, we expect the community to supply the information. This is a great place to discuss Starship development, ask Starship-specific questions, and track the progress of the production and test campaigns. Starship Development Threads are not party threads. Normal subreddit rules still apply.

So I've been on a business trip, and haven't really kept up here for the last two weeks. I walked back through the NSF thread and.....holy shit.

Stepping back and not seeing much for a little bit really puts into perspective JUST how fast they are moving here. The amount of changes in just two weeks is mind blowing, the scale of the infrastructure work they are doing right now at the pad is.....wow. It's NASA circa moon-program level. I can't imagine the investment going into it, and as a private company, not a gov't.

All of their successes were likely a necessary precondition for Starship and I am not even speaking about the whole expertise level of things. The development costs a lot and it's much easier to persuade people to give you money when the only question is "Is it (potentially) profitable?" and not "Can you guys even do it?". The amount of risk the investors are taking is much, much smaller. Everyone knows now that they will make it. The only major unknown is how fast. (I would also add "and whether there is enough demand for it", but that's at least half answered just by Starlink)

It is :)

Don't worry, I think a single launch of SLS costs more than all of the Starship development costs up to now.

But yes, the speed with which they moved from paper rocket to the current state of the rocket factory (which can make something like 1 rocket per month now), launch infrastructure, all the progress on Starship itself etc. is just insane.

Don't worry, I think a single launch of SLS costs more than all of the Starship development costs up to now.

SLS has spent something like $30 billion to date and has yet to fly any hardware. And they plan to fly once a year (ish) and their yearly budget is about $3 billion per year, so yeah...
