Also, with only one drone ship SpaceX loses the ability to recover Falcon heavy side cores on the ocean. It’s RTLS or sacrificing the whole stack to the dark gods of delta V.

Fun fact, this is the second landing barge named Just Read The Instructions, the first was retired after two failed landing attempts a decade ago.

After 156 successful Falcon 9 landings, Just Read the Instructions will be fully dedicated to support Starship operations going forward

@peterrhague I wonder what it would sound like if they did a longer pulse bc most of that just sounds like the valve, same with the sounds we’ve heard of dragon
English
Has any science fiction media correctly portrayed what RCS bursts sound like?

Onboard video of the CM RCS hotfire. "Knock, knock. Sound on for the first seconds our reentry thrusters fired. It was a checkout on the eve of splashdown so we were relieved when it went perfectly." #ArtemisII instagram.com/reels/DXKnBmDv…

@Starship_block3 @Echo5550 how tf is the TWR 1.3 it looks like it’s like 1.8
English
Fun fact about that core stage for those who might not know
That thing has a TWR of 0.78 without SRBs when it is completely fueled. The SRBs are needed to increase TWR to ~ 1.3.
Imagine if the core had like 8 RS 25s. It could get into NRHO by itself (haven't done the math)

SLS under 8.8 million pounds of thrust, sending the Artemis II crew around the moon for the first time in over 50 years.

@r3a9an_k_ @TrackingTheSB yeah since they’re staying in earth orbiting for a day the prop would boil off so they couldn’t use ICPS anyway hence them repurposing it for this
instead it does most and the rest is done with the ESM but that also prevents them from entering lunar orbit due to less fuel left
English
@Tygget @pintleinjector i dont even think they can fix that so not necessarily a positive sign
English
@pintleinjector LAS battery still being a little funky last I heard but the closeout crew has left so idk
English
@Cosmic_Andrew1 it’d be really funny if he messed it up again
English
@EuroMotoTrack @SenMarkKelly Starship is great and will be able to do a lot but it’s far from being ready especially to launch crew
Yes SLS probably never should have happened but it’s here for now and is clearly the best option, commercial rockets will take over with time
English
@SenMarkKelly right and if they gave the contract to SpaceX we would have done this years ago you wanker
English
This engine is what is going to help bring our astronauts to the Moon later today. Decades of American innovation built this. Today we get to watch it work.

@SenMarkKelly If that’s the engine they’re using today they better strap it onto the rocket!🤪
You’re searching for relevance & we really don’t care!
Yes it took decades & nearly $100B with each launch costing $4B!
Starship has been privately funded & costs $10M to launch!🚀
Do the math!🤡

@itsfine2022 @NASASpaceflight also even if something went wrong maybe they’re still confident enough to just put the rest of the engines on and fix the problem at the same time and just start ramping up after all that work is complete
English
@NASASpaceflight Everyone assumes something went wrong. What if the the static fire was more for stage 0 and not the booster. B19 needs the rest of its raptors it will be back for a full static fire
English
Booster 19 is heading back to the Production Site:
StarbaseTracking@TrackingTheSB
A new road delay has been posted. Additionally, the booster transport stand has been moved back to Pad 2.
English
@deltaIV9250 nah booster 7 got like SN4 of the raptor 2s this is a lot better
English
These serial numbers on these raptors are awfully low

This rocket had such a goofy ass failure. Like bros engine just gave up 😭😭

@Jack_Frodo @SpaceGeekSheri massive metal plate that cuts through the propellant right in front of where it’s burning and cuts it off
English
@SpaceGeekSheri just goofing around because they are known for not being able to be shut down. it’s probably impractical to create this tbh. i’d be curious to see what it would take though!
English
@booster_10 It was such a tense moment I really thought it was about to RUD on the pad
English
I still remember sitting there waiting to see if Flight 1 would lift off after it lit it's engines, it felt like it just sat there for an eternity before finally beginning to rise.
English
@RyanHansenSpace @JohnFubka @r3a9an_k_ @CrosaJM @CSI_Starbase what I don’t understand is why they’re not changing the engine to address the ice in the first place bc whether it’s being filtered successfully or not they can’t rapidly relaunch with tens of tons of water in the bottom of the tank so something has to be done eventually
English
Those are the same inlet filters used on previous boosters. This includes the boosters that had filter blockage during boost back, causing booster RUD. They added a larger ice strainer structure on later boosters above these filters. @CSI_Starbase and I made a video about this a while back, and B13 remains basically validated that concept.
English
We can see now that the lengthened leeward chines that once held CO2 tanks are now filled to the brim with COPVs
My theory is these new COPVs carry gaseous oxygen and methane to pressurize the tanks so they dont have to use preburner exhaust anymore
What about it!?@FelixSchlang
Our flyover photos are coming in now. Here are a few more views from Massey's. Booster 18 experienced an anomaly during gas system pressure testing. 📸: @Jordanguidry6
English
@ScottLikedSLS @spaceflight1905 Didn’t raptor 3 also just fix the ice issue by no longer taking autogen gas from the preburner?
English
@spaceflight1905 they don't do BB with the main LOX tank now, no ice to suck in
English
Light speculation:
By the amount of COPVs B18 had it feels like instead of removing the RQDs and putting it through the 2 QDs they just moved it to the Booster instead.. while this adds mass to the booster it also means its possible to restart an outer 20 engine during flight now
English
@KenKirtland17 @J8kePainter Can you make a limited edition booster 18 version that explodes as soon as it touches a drop of water
English
Little known fact: Falcons 9 Octowebs use their legs to walk around like this until they find a tank to attach to.
English
@_FrankyPi @RyanHansenSpace @mondiani @KenKirtland17 @DrChrisCombs By that logic SLS development started in the 1970s
English
@RyanHansenSpace @mondiani @KenKirtland17 @DrChrisCombs They already had full build Raptor tested on a stand in 2016, so giving it that would be quite generous.
English
What date/year would you consider the "start" of the Starship program?
How much has it cost?
Would you still call it "fast"?
Not trolling, genuinely trying to get a feel for what people think. These things are all ambiguous and makes comparisons to other programs challenging
