@GeraldG42 @Simon_BG @SunflowerEvryDy @PDM_EVinvest That's a crazy level of grasping at straws.

@niccruzpatane Got some hinge damage though

[Hegolas @JenningsSVK]

@bbCaulk @CSI_Starbase There shouldn't be any real slosh to speak of during the landing burn as the LOX landing tank is fully enclosed and full and CH4 transfer tube is pretty narrow and also full.

@SawyerMerritt Me, yesterday :

[Hegolas @JenningsSVK]

@r0berto_mid_5 @PfPopulist Yes, you're probably that aswell lol

[Hegolas @JenningsSVK]

@r0berto_mid_5 How many countries have you visited in your life?

[Hegolas @JenningsSVK]

@Stomping_Zebra @mcrs987 It's certainly making my head spin just thinking about the problem. Actually implementing that control algorithm?

I really don't find it too likely. I think it really was just a shield inspection and SpaceX will focus on eliminating any chance of roll instead of correcting it.

[Hegolas @JenningsSVK]

@Stomping_Zebra @mcrs987 Damn. Canceling a roll with just one off-axis engine at the same time as trying to cancel vertical velocity & pitch angular velocity for a tower catch certainly sounds like a GNC engineer's nightmare.

[Hegolas @JenningsSVK]

@josramirezmor @Saadusmani78 @mcrs987 You literally just watched one of those simulated catches.

[Hegolas @JenningsSVK]

@SpaceInMiBrain @r3a9an_k_ They can't really do that reliably. Any miniscule difference in ignition timing between engines will push the booster off axis, which will in turn amplify the push further. The choice is between leaving the direction to chance or pushing it in the direction they want it to go.

[Hegolas @JenningsSVK]

@Maximus69foLife @DaveF63 @r3a9an_k_ You're quite rude about it but also totally correct.

[Hegolas @JenningsSVK]

@DaveF63 @r3a9an_k_ We can see one such interaction during flight 12 : as soon as the booster moves off axis and the gridfin gets blasted by the plume the booster enters into an uncommanded roll

[Hegolas @JenningsSVK]

@DaveF63 @r3a9an_k_ There is no reason to flip intentionally in a diagonal direction. It just introduces extra variables (like uneven gridfin-plume interactions) for no gain at all.

[Hegolas @JenningsSVK]

@r3a9an_k_ You're thinking about this in the right way but your red arrow is directly opposite to the direction the booster would be pushed to as a reaction to those two RVacs being lit.

[Hegolas @JenningsSVK]

@MihirPanchaal @SpaceX I concur.

[Hegolas @JenningsSVK]

@Croft_Racing @Meatloaf_TTV @SpaceX That might be as a precaution for if they miss the target by ~15 meters. A roll like this gives them the leeway to land just outside of the buoy perimeter in whichever direction and still be able to get a clear shot of the heatshield. Purely an ad-hoc speculation

[Hegolas @JenningsSVK]

@hair_ass68324 @SamuelD2022 @CamCutApp @Tesla_AI @DevinOlsenn Nice bait

[Hegolas @JenningsSVK]

@RedlineRory @SawyerMerritt Can't really avoid that shit no matter what you do
