So basically less mass, more thrust. They didn't gave the costs, but probably easier to manufacture. Also, less components means better reliability.

Raptor 1: First Edition. Proof of concept of FFSC on a methalox engine.
Raptor 2: Simplify, reduce weight, increase thrust.
Raptor 3: Simplify, increase robustness for operational environment, reduce weight, increase thrust.

It would probably need a bit of refueling near the Moon though. Especially if you're not aerobraking for the return

New Glenn is supposed to launch in september 2024, but the tests are still going on.
I guess we'll have to move it again, august 2026 of everything goes fine and fastly.

i'm still baffled how they got all of that inside the walls.
it's never gonna happen of course but i'd love to get an X-ray view of where all the remaining wires and pipes are hidden inside the main body of the engine.

Your web browser actually does a hell of a lot more than it did 20 years ago. Try an old OS with an old browser in a VM to see.

Yeah, sure, they're going to launch a Dragon for $267k...
It could be related, though honestly, studies for "hey, what if we kept a capability to launch a rescue spacecraft at a 1-2 day notice in case of something happening" should have already been made

Worrying about it is racist, because there are plenty of Africans and Indians that can replace the missing white people, but the Great Replacement is a conspiracy theory, but cratering western birth rates and sky-high immigration are good things.

Not a single one of those accusations are backed up by anything, it's just aimless schwitzing.
How sad that even being the son of Elon can't save one from the induced brain death of transvestitism.

His other brothers of the same age seem to be ok so maybe vi[v]llainous isn't very trustworthy
and of the soundest mind but idk..
Also, kind of reminds me - anyone remember that German suspected trans that was Elon's assistant or something? I think their name was also Vivian. At least s/he was a fan of SpaceX/tesla. Wonder what happened to her/him.

Quite a few flights are still going to be raptor 2s, they have produced 569+ examples of raptor 1+2.
Raptor 3 is going to be part of some of the big revisions to booster and ship in the future.
The next flights should be fine in terms of engine reliability. Some of the biggest issues on engines come from ship and booster. Last flight had a real shaky landing burn because of low pressure in the landing tank, they have added additional pressure vessels almost directly on the tank to help fix that.
