Three weeks after Flight 6, SpaceX has static fired Booster 14 and is making ready to roll Ship 33 to Masseys to finish its personal engine testing. Once each automobiles are examined, SpaceX will start the ultimate drive to Flight 7, probably launching in January.
Booster 14
On Dec. 5, simply over two weeks after Flight 6, SpaceX rolled out Booster 14 to the launch web site. It was then lifted onto Orbital Launch Mount A (OLM) early within the morning on Dec. 6. Teams then proceeded to carry out a Tanking take a look at and a Spin Prime concurrently on Dec. 7.
A tanking take a look at includes SpaceX loading Liquid Oxygen (LOX) and Liquid Methane (LCH4) onto the automobile for testing functions. Internal adjustments could have been made since Booster 14 accomplished its cryogenic proof take a look at on Oct. 4 and 5. SpaceX has performed two flight checks since then.

Then, on Dec. 9, groups loaded up Booster 14 once more, this time performing a 33-engine static hearth. With this out of the best way, SpaceX rolled Booster 14 again to Mega Bay 1 for closing modifications and checkouts earlier than Flight 7, which isn’t any sooner than early to mid-January.
Booster 14 is kind of an identical to Booster 13 on the skin aside from the ship engine chill pipe extensions on earlier boosters. These are now not wanted as Block 2 of the Ship has its engine chill pipes working via the aft flap fairing with a flare outward on the backside. This helps simplify the connection between the Ship and the Booster and reduces mass.

Ship 33
SpaceX moved the Static hearth stand again from Masseys and has since parked it within the previous ring yard subsequent to the Starfactory. This means that Ship 33 is slated to roll out quickly for engine testing at Masseys. However, SpaceX had two nighttime closures that gave the impression to be for Ship 33 to Masseys however had been as an alternative used to carry new Orbital Tank Farm (OTF) horizontal tanks from the port.

After solely beginning stacking operations simply 5 months in the past, the primary Block 2 ship of the Starship program ought to static hearth inside the subsequent week or two. This timeline of stacking, cryogenic proof testing, and engine testing is a brand new document for SpaceX concerning an orbital class Starship.
In the previous, with Block 1 ships, it might take eight months or extra to achieve this level within the constructing and testing movement. This reveals the numerous strides SpaceX is making in refining the design of Starships.
Block 2 Changes
Ship 33 has many adjustments in comparison with Ship 31 and previous ships, as it’s the first Block 2 ship. First and foremost for Block 2 are the prolonged propellant tanks. SpaceX added a hoop on the ship, making it 21 rings tall, and moved across the frequent and ahead domes to have the ability to load 300 extra tons of propellant into the ship. This addition will enable SpaceX to extend its payload to orbit with Block 2.
The sacrifice was a smaller payload bay part, which went from 5 rings to 3 rings. However, SpaceX retained most of its usable payload area, because the nostril cone on Block 2 was utterly redesigned. SpaceX saved the payload quantity excessive by compacting and simplifying the header tank bundle within the nostril cone and considerably decreasing the scale of the flap body contained in the nostril cone, thus giving area for cargo.

The Block 2 pez dispenser for Starlink satellites is now bigger than the earlier Block 1 design, growing the variety of Version 3 Starlinks from round 40 to 54.
The different noticeable change is that the ahead flaps have turn into thinner and are being moved barely up and leeward or away from the warmth defend aspect of the ship.
On Block 1 ships, the flaps had been 180 levels aside, and as seen on the previous few flights, SpaceX has had heating points on the flap hinges. Block 2 solves this situation by shifting the bottom of the flaps, the flap hinges, and the fairing to 140 levels aside and out of the principle plasma stream for reentry. This will assist forestall the warmth buildup and burn via seen on the final three ships which have flown.

The subsequent important change is the warmth defend. SpaceX has eradicated a lot of the adhesive tiles throughout the complete ship. In the previous, the part and dome welds would have glued tiles, as would the ahead flaps. On Block 2, SpaceX changed these with smaller pinned tiles. These will keep hooked up to the automobile a lot better, permitting for much less of a spot between the tiles.
Now, as SpaceX prepares to attempt to catch a ship, presumably as early as Flight 8, the lifting factors want to maneuver down in preparation for attaching the precise catch {hardware} to the ship. SpaceX can not catch with the present chopstick {hardware} that’s onboard ships. To that finish, SpaceX has moved the chopstick elevate factors right down to the payload bay reasonably than below the ahead flaps as with Block 1. This additionally means the chopstick stabilization factors have moved to the frequent dome.

With this transfer, SpaceX additionally needed to redesign the two-point lifter to elevate Block 1 ships. This resulted within the four-point lifter, which attaches to the chopstick elevate factors and a stabilizer level within the nostril cone. With 4 factors of contact and a bumper, this technique is way extra secure, and SpaceX even makes use of it to stack the ship after the nostril cone and payload sections are joined.
As for inside adjustments, Block 2 has 4 switch tubes going from the frequent dome to the engines reasonably than one like in Block 1. The three additional switch tubes are for every Raptor Vacuum engine, whereas the middle one is for the three middle engines. This change will assist enhance propellant movement to all of the engines.
In addition, Block 2 now has elliptical domes for each the ahead and customary domes. This change helps with manufacturing and retains the design simplified.
Overall, the Block 2 ship is constructed far more like a booster than Block 1 ships, as extra stringers have been added within the engine part and the methane tank. This ship is the fruits of many classes realized through the previous 5 years at Starbase.
So far, solely Ship 33 has gotten engines, that are Raptor 2s. However, as soon as Raptor 3 turns into a extra mature design, Block 2 of the ship also needs to get them.
Stay tuned for a video from NSF detailing much more adjustments made through the Block 2 design of Ship.
And right here come Ship 33’s Sea Level Raptors. SN385 in view. With Flight 6 simply across the nook, Flight 7 and the primary Block 2 Ship are deep into preps.https://t.co/e3xbqPnwZ5 https://t.co/hM1LrXt1jq pic.twitter.com/6ml56LdnCa

Orbital Tank Farm
Heading into Flight 7, SpaceX is starting to extend the capability of the Orbital tank farm with not less than two new Liquid Methane Tanks and two new Liquid Oxygen Tanks. This will assist recycle occasions after a launch try and improve the capability for when Pad B comes on-line.
It is unclear if these can be put in and piped in for Flight 7 or later, but when put in earlier than Flight 7, anticipate SpaceX to carry out a Wet Dress Rehearsal to check the brand new tanks, piping, and, after all, the brand new Ship design.
