How are you feeling about the upcoming 33 Engine Static Fire attempt?

It kind of sucks that booster 8 was scrapped. It would have been cool to see SpaceX retrofit the vehicle to allow the CH4 tank to be used as a water tower. The downcomer is almost the perfect diameter for this job

The Raptor Service platform has been transported away from the Launch Complex. This is definitely a first, and an odd one at that. Assuming it requires some maintenance or something because moving for static fire seems a bit excessive.

It's important to note that these are most likely not for storing water, but to function as gigantic water hammer arrestors. This system still needs a very large water supply that currently does not exist.

First new mounting brackets installed underneath the Methane bleed line. This is a sign that SpaceX is intending to install a shield over all of the horizontal cryo tubing on the OLM. More of these have been installed tonight to the left of this position 📸

I definitely need one of these! 🔥🔥🔥 #StageZeroZack

Thank you all for the overwhelming support for my LEGO OLM♥️ I'll share more pictures and show off all its features in the coming weeks - starting with an aerial view showing the Booster QD and the 20 clamps that are meant to support the full stack! How did I do, @CSI_Starbase?

It's always easier to destroy than it is to build. Check out this timelapse of the removal of Thermal Protection System Tiles from Ship 22's scrapped tank section. Looks like a job that you might have to win 2/3 rounds of RPS in order to be selected for. 🎥

It will be a busy night at the Starbase Launch Complex. Water deluge equipment now arriving by the truckload. It's pretty rare for equipment to show up and be installed immediately here. Oh yea...pretty decent sunset as well tonight. 🎥:

Seems pretty clear now that SpaceX intends to have this water system installed ASAP after 33 engine SF. Grover appears to be getting set up for lifting tanks once they arrive to the launch complex. 📸:

SpaceX’s water deluge equipment from Pad 39a will be arriving to Port Isabel tomorrow. What happens after it arrives, will be very telling as far as whether or not we should expect it to be installed before OFT1

Excellent interview by asking some great questions about the #Starship program!

11/11) Obviously this won't work with the current vehicles, but is an option to consider on future iterations. It severely violates the "best part is no part" rule, but figured I would throw the idea out there anyways. Thanks for reading and hope you enjoy your weekends!

10/11) This can be duplicated on the CH4 tank by routing a vent line up through the interstage and connect it to the Ship QD. From here the depress from the booster CH4 tank can be routed through the Ship QD's Methane bleed line. Boom no more venting to atm 📸:

9/11 ) Not sure how this fitting works, but it apparently requires no manual connection. Once the chopsticks set the ship on top, the raptor chill vent is relocated below the booster's grid fins, and more importantly, below the cameras on the GSE arm. 📸

8/11) Now, there is a possible solution that would allow SpaceX to depress the top of this tank during the last 5% of fuel loading without venting to atmosphere. Its basically the opposite of what we saw them do with the Ship's raptor chill vent. 🎥

7/11) There is approximately 4.52 meters from the outlet of the vent, to the top of the tank dome. If the vent was located on top of the dome, then there would be no chance of liquid flowing out of it, only gas. But that is simply not how this is designed 📸:

6/11) When the CH4 tank is being filled gas pressure will begin to build up at the top of the tank as the liquid boils off. There is a certain point during the fill process where this must be released in order to continue filling the tank. 🎥

5/11) Now, that we can confirm this is LIQUID above that line, we can say for certain that once this valve opens a significant volume of LIQUID methane begins draining from the tank. Kinda sketchy, but there is a good reason for why this is necessary. 🎥
