Any news on latest launch timing? I remember it was NET Dec31, haven't heard updates recently.
The first Vulcan Centaur is fully built. The latest Falcon Heavy is fully built and its predecessors have flown successfully eight times already. While New Glen is not complete, much of its hardware is, and its flights are to be more or less standard single-launch missions.We were supposed to have an Xmas Eve launch of Vulcan Centaur and that was scrubbed, we were supposed to have a Falcon Heavy launch and that was scrubbed, we were supposed to have New Glenn soon as well, and that's nebulous since they are so secretive. Frankly, I predict Starship will be going to the moon before any of these other systems get off the ground.
Yes, but the Raptor is a staged combustion engine. All fuel/oxidiser entering the system goes out through the nozzle.Everything is different engine to engine design, but the chilldown is usually only the turbo, machinery.

Starship has yet to achieve orbit or survive flight. In order to go to the moon, a tanker version has to be built and tested, an orbital propellant debot has to be built and tested, more than ten and possibly as many as high-teens tanker launches will have to be made to fuel the depot, and only then can a Starship be launched that will be able to go to the moon.
Even if we're talking about a free-return trajectory of a standard Starship, not the HLS, and even if the tankers and oribtal depot already existed (they don't), I find it next to impossible that SpaceX can achieve at least a dozen successul launches of at least three different versions of Starship (tanker, depot, standard) before Vulcan can fly or Falcon Heavy can fly again. I even expect New Glen to fly before any form of Starship goes to the moon, though I wouldn't bet a ton of money on it.
Yes. Ariane 6 is another long-delayed rocket I expect to fly soon, and like Vulcan Centaur, I suspect odds are good the first flight will be successful.Agreed. The Falcon Heavy is already proven, so that one really shouldn’t be in the “race”. It’s really between the unproven systems — Vulcan Centaur, New Glenn, and Starship. I wouldn’t be surprised if Vulcan Centaur flies successfully the first try. New Glenn and Starship are trying something new for both companies, and it might take awhile, but I bet Starship makes it to orbit first, while New Glenn makes it to orbit before Starship lands on the moon.
Maybe they need to launch a Tesla Semi into orbit the next flight.Discussion of cause of failure of Starship in flight 2:

SpaceX, being a privately held company, doesn't issue an annual report that I know of. Therefore, we don't know what they have in the bank. However, it can be reasonably guessed that they make a few million dollars profit from each Falcon 9 launch, especially at this point where the large majority of Stage 1 is on it's 10+ reuse, therefore, the biggest cost to SpaceX at this point is propellant.Musk is just paying for it himself. Yeah he can charge to launch commercial stuff but I bet the insurance premiums would be substantially high on the payloads at this time. I think they'll eventually get the bugs and gremlins worked out as long as Musk doesn't run out of money.
One change is that they are going ahead making IFT-3 an orbital attempt rather than sub-orbital to consume more propellant. They may also include a partial payload of satellites to be released to test out the "pez dispenser". This will add mass that will require the propellant to be used up so that they don't have to bleed excess oxygen or fuel which in turn should increase safety because of not bleeding it out.Maybe they need to launch a Tesla Semi into orbit the next flight.
SpaceX's iteniterative approach to design is such that Starship is unlikely to have a complete lock-down in design but rather improvements made on each flight. Each flight will have additional changes, improvements, and missions. Version 2 will fly after then next 4 IFTs and Version 3 (extended booster and starship) will fly at some point in the future. They have to test it to make it an efficient launch vehicle, they test it as a fuel depot, then as a payload vehicle, then test it as personnel vehicle before eventually completing a landing vehicle. All different versions. 4 IFT launches are scheduled for this year so I don't expect a usable version until sometime next year even if every goes as planned....
Starship will eventually work, even if it takes 10 more IFTs to get things right. And I predict it'll be much sooner than that.
In 3 or 4 years, Starship flights will be so routine, we'll start ignoring them.
They will need to stop improvements at some point after the 3rd config and before finalizing the 4th (manned). Once they go to get the "man rated" certification, the speed, and type if changes need to slow to a crawl.SpaceX's iteniterative approach to design is such that Starship is unlikely to have a complete lock-down in design but rather improvements made on each flight.

They filed at the end of January according to several reports.As of February 7th, SpaceX still has not filed their mishap report with the FAA, which will be required to get the launch license for the third attempt.

It's possible that both are accurate--SpaceX may have filed its report and FAA may have asked for more info that SpaceX has not yet provided.
You know that every US air traffic controller is an FAA employee, right?I sort of wonder if the FFA has a department for dealing with spaceX/musk, it’s probably the biggest one
Yup that’s the point of the joke.You know that every US air traffic controller is an FAA employee, right?
I mean, yes. Because those are major parts of its job. That's sort of like saying that the Secret Service splits its time between investigating counterfeiting and protecting the President.It sort of seems like the FFA splits its time between planes and approving all the spaceX stuff.
Really! I was trying to make a stupid joke! I guess they could try getting computers to do air traffic control?But there is also an issue where the FAA doesn't really have enough staff right now to keep up with the increase in space launch activity.
