Hey #StarshipAddicts It's been a while since I've done this but here's a short thread explaining what is about to happen at the Starbase Orbital Tank Farm
1) Last week this trailer arrived to the Sanchez Gas site. As of yesterday it appears that SpaceX has started to move these items over to the Launch Complex, which is something I wasn't expecting until after the first Orbital Test Flight. Here's why...
2) At the OTF there are currently two active liquid oxygen pumps (green). To the left of those are two additional inactive pumps which were delivered back in March (red). So why weren't these ever fully installed?
3) The reason these weren't installed is because it will likely require SpaceX to halt all testing at the Orbital side of the Launch complex. The manifold shown in (1) will have to be inserted into the position shown here. This is the suction side of the LOX pumps
4) The manifold for the discharge side of the pumps has not yet been spotted. You can see in the first image that SpaceX has not yet applied the final white insulation wrapping and the required labels as shown in the second image.
5) This expansion has been in progress for a while on the methane side. The difference is, the CH4 side was (for the most part) prepared for this expansion from the very beginning. The necessary T fittings for adding additional pumps can be seen here.
6) Once the two new CH4 pumps were delivered, all that was required to integrate the two pumps was an extension to the manifold on the discharge side. In this image you can see that @RGVaerialphotos happened to catch pump #3 in the process of being lifted into place.
7) So these are the things I can say for sure. There are several remaining questions however. Is SpaceX planning a 2X increase in how fast LOX can be loaded onto the Starship, or will they max out at 2.5X increase by adding the 5th pump as well?
8) Is it possible to cut the proppant loading time in half by adding these pumps without also increasing the amount of heat exchangers as well? There are spots for 4 additional (2x increase) heat exchangers to be added in these location
9) Opinion #1: Unless the plan for these additional pumps is to simply be used as backups in the event something happens to either of the primaries during a testing event, then I would expect at least 2, if not all 4 heat exchangers to arrive sometime soon.

10) If so, then they might as well add the remaining two for the methane side as well. Based on this capped off T fitting present in this location, I would say SpaceX is already somewhat prepared to add at least one additional heat exchanger.
11) I have shied away from posting threads like this because I don't want it to be used as the script for the next "SpaceX Fans" YouTube video again without permission🖕🏾. But I already know I won't have time to cover this in my next episode so...here ya go!

1/11) Hey #StarshipAddicts, I just wanted to take some time to correct some misconceptions I have seen floating around about this event during the WDR. Hopefully this thread will clear the confusion. At the end, I will suggest a possible solution to this issue.
2/11) To start off, we should all be able to agree that Wet Dress Rehearsal involves Liquid Methane, and Liquid Oxygen. There is zero nitrogen involved, other than for super chilling of propellants and various gas purges (interstage & OLM/OLIT)
3/11) Now, lets take a look at the depressurization vents on top of the methane tank of the booster. There are no pipes on the inside of the tank that connect to these valve. So when they open...you can literally stick your arm inside of the booster methane tank

(1/4) Hey #StarshipAddicts, here's a little update about the status of exterior cladding on the Orbital Launch Integration tower.
As of today, the first 3 levels of the OLIT have been covered on the sides facing the Launch Mount.
What is the status for the rest of the tower?
(2/4) More paneling for the tower has been spotted by @RGVaerialphotos at the Massey's site which is owned by @SpaceX.
As shown in this image, there are 18 bundles of tower cladding. Each bundle has 9 panels. There are a total of 162 center panels on site already.
(3/4) Each level of the tower requires 4 center panels. Doing a little math...
Panels Available =162
Number of sublevels on OLIT = 24
Remaining levels without cladding = 21
Panels Needed for each side OLIT after bottom 3 levels are covered = 84
This piece of equipment is the main reason for using the #LR11000 Super crane to lift the booster, instead of the #Chopsticks. I'm going to refer to it as the Locator Pin.
(2/11) When fully extended, the locator pin is inserted into this position on the starship #StarshipSuperHeavy's Hydraulic Power Units (#HPU's). There are two of these located on either side of the booster.
(3/11) I'm not sure if the aero cover actually makes contact with this hard point on the booster, but its not meant to take much force either way. In order to not damage the booster, these locator pins are designed to have a relatively light tough.
(1/8) #StarshipAddicts, I think we have a major update for you about one of the #Starship variants we have been expecting to see at #Starbase!
It has been speculated that this nose cone barrel section was to be used for the #CargoVariant.
(2/8) Thanks to @RGVaerialphotos, we now know what it looks like from above. In this image you can see in interior structure which is most likely used to open the "payload bay"
(3/8) If you watched the most recent episode from @RGVaerialphotos flyover review you will remember us mentioning that the size of this payload door makes a lot more sense for #HLS#LunarStarship than it does for #Cargo version.
(1/10) Hey #StarshipAddicts! If you didn't get a chance to check out the latest @RGVaerialphotos Flyover review livestream then you missed some interesting details about new progress around #Starbase. Here's a summary of last weeks top finds. A lot of info in this image alone!
(2/10) CH4 Storage Tanks:
The tanks shown in this picture are assumed to be the additional Methane storage tanks needed in order to fully fuel a #Starship/#SuperHeavyBooster for orbital launches and also suborbital WDR / Cryo testing on the new staging pads.
(3/10) CH4 Storage Tanks: @LabPadre#Gatorcam caught these four tanks rolling into the port on a barge on the morning of Feb 15, 2022 at KSC. These are identical tanks to the four tanks that we have seen at the Sanchez site.
(1/14) Hey #StarshipAddicts , @CSI_Starbase has concluded that #B4 is NEVER going to leave the ground under its own power & #B5 is just a massive lawn ornament.
#StarshipSuperHeavy#B7 is up next, lets look at some of the difference we have noticed so far!
On the FWD dome we see a new design for the stage separation clamps. These may have not been completed yet on #B7 but the initial shape of them is a departure from the previous boosters.
Autogenous pressurization lines have been moved higher up towards the top of the #CH4 tank dome instead of below the stringers like the #Block1#SSH's (Sorry not sorry for making new acronyms)
Anyone else wish this was related to Hot Gas Thrusters?
