This thread probably, next thread perhaps less likely?

• LR11000 crane is hooked up to remove a remaining portion of GSE-2 outer tank.
• Build site video tour: Parking garage construction continues, Starfactory cladding is nearly complete.
• S29 & B11 partial tanking test: NSF livestream. GSE venting (ship methane subcooler), B11 CO2 tank venting, LOX subcoolers venting, tower venting, (alternate angle), frost on ship and booster, depress vent, and road open. NSF timelapse.

Starbase activities (2024-06-14):

• Jun 13th addendum: B15 LOX barrel arrives outside the Megabay.
• Build site video tour: Work on B15 LOX barrel. Unusual water fountain/deluge test.
• S30 tile removal continues. Starship Gazer video.
• Tower B: Overnight, three wall section panels are staged near the tower corners which were erected the previous day.
• The first crossbeam is added between the tower corner sections.
• The first wall panel is installed and reinstalled a short while later.
• Continuous flight auger (right) continues work nearby.
• CC8800-1 crane assembly continues. All three main winches are installed.
• Massey’s: B14.1 “hat” is removed.

Starbase activities (2024-06-15):

• Tower B: Overnight, corners 3 and 4 are erected. Starship Gazer photo 1, photo 2.
• CC8800-1 hook block arrives.
• RGV Aerial posts photos of Pad A aftermath, Massey’s flame trench, S30 scaffolding, Pad B construction, and a six-year side-by-side comparison of the build site.

IFT-5

• Booster catch NET late July, per Elon.

Starbase activities (2024-06-16):

• Morning photos of the launch site from cnunez: photo 1, photo 2, photo 3, photo 4, photo 5
• Tower B: Wall panel installation continues. (alternate angle photo from Doherty)
• CC8800-1 crane assembly continues. Derrick is raised.
• LR11000 moves towards the old orbital tank farm.
• Peek inside Starfactory and Megabay 1.
• S30 tile removal continues.
• New Ringwatchers article on the B14.1 test tank.
• RGV Aerial spots a thrust ram which hints at a 5-10-20 arrangement of engines for a 35-engine booster. For context, the current boosters have 33 engines in a 3-10-20 arrangement. Render and analysis from mcrs987 (TheSpaceEngineer), along with speculation on landing burn engines and redundancy.
• Opinion: I think the 3-engine landing burn looks plausible with differential thrust, but I’m not sure if the 2-engine landing burn would work. You’d have to gimbal the engines to point through the center of mass, and land with the vehicle tilted a la SN5 and SN6. Could the chopsticks compensate for that?

Starbase activities (2024-06-09):

• Relatively quiet day.
• Overnight, B15’s A3 section enters Megabay.
• Some sort of security exercise occurs.
• Work on OLM and chopsticks continues.

IFT-5 info from Elon:

• Launch NET one month from now.
• S30 heat shield to be replaced with tiles which are twice as strong, and adding an secondary ablative protection.

Starbase activities (2024-06-02):

• Jun 1st addendum: NSF timelapse of stacking, and ship transport stand rolls away from the OLM.
• Launch site: Excavator is lifted. Work on pad 2 is progressing (closeup of tower foundation rebar).
• Starship Gazer photo of the full stack, and closeup of missing tiles on ship.
• ‘GATEWAY TO MARS’ sign is loaded onto a trailer as ‘ƧRAOM⅄⊥AGAEW’.
• Build site: Ship lifting jig is loaded onto an SPMT and enters Highbay. Nighttime photo of Starfactory from cnunez.
• Recent RGV Aerial photo of entire build site.
• Starkitty sighted :)
• S26 still at Massey’s.
• New Ringwatchers diagram is posted. Parts spotted for S36, S37 (Starship v2), B16, and B17. Tweet with additional list of updates.

KSC

• Final tower segment and both right and left chopstick arms leave the Roberts Road site and arrive at the turning basin. Max Evans video.

Starbase activities (2024-06-13):

• Overnight, the 10 launch mount hold-down clamps which were removed are replaced. The first and second booster stabilization pins are reinstalled on the launch mount.
• Parts for the CC8800-1 crane continue to arrive. Aerial photo of assembly from a couple days ago.

• Tower B: Corner 1 of 4 is erected (wide shot, closeup 1, closeups 2, closeup 3). Corner 2 of 4 is erected not long after (closeup).
• The barge carrying the remaining tower hardware rounds Florida’s tip on route to Brownsville.

Other:

• FAA licence modification followup: “The FAA’s most recent license modification approval for Starship Flight 4 allows for multiple flights of the same vehicle configuration and mission profile. If SpaceX decides to change the mission profile or make other changes that affect the safety analyses, it will need to request a license modification.” It is unclear if a booster catch attempt would require a modification to the launch licence.
• Twitter thread from Benedikt summarizing the foundation for the new tower: Tweet 1, tweet 2, tweet 3, tweet 4, tweet 5, tweet 6, tweet 7, tweet 8, tweet 9, tweet 10, tweet 11, tweet 12, tweet 13, tweet 14. u/TwoLineElement’s corrections are noteworthy.

• Overnight, cars to the pad.
• Mary evacuates, OLM and tower venting (ViX, NSF), frost on ship (ViX, NSF), engine chill,
• IFT-4 happens :)
• Jun 7th and 8th road closures are revoked. No surprises there.
• Road delay for booster transport to Massey’s is posted for Jun 8th 00:00 to 03:00.
• Post-launch photos of the pad from Starship Gazer and Jack Beyer.

IFT-4:

• Liftoff, hot staging, hot stage ring jettison, booster splashdown (landing coordinates), ship coast phase, reentry and partial flap disintegration, ship splashdown is confirmed.
• Chopsticks slowly close shortly after booster splashdown.
• Clear shot of disintegrated flap hinge. (annotated)
• Flap hinge was an anticipated weak point, and will be addressed on newer ships by shifting the flaps leeward.
• A WB57 was near the booster landing location, and a Dassault Falcon 900EX was near the ship landing location. RGV Aerial performed a flyover in the afternoon, likely to the booster landing location. Hopefully these planes got some good footage.

KSC:

Other:

• SpaceX confirms that the missing heatshield tiles are intentional experiments.
• ViX tally of recent cryo deliveries to the Starbase orbital tank farm.

• Up to 44 launches per year with both pad and drone ship landings
• Separate catch and launch towers
• Liquid methane, LOX, and LN2 produced on site.

Elon tweet on heat shield tiles: https://x.com/elonmusk/status/1796049014938357932

Unless we make the heat shield relatively heavy, as is the case with our Dragon capsule, where reliability is paramount, we will only discover the weak points by flying.

Right now, we are not resilient to loss of a single tile in most places, as the secondary containment material will probably not survive.

I will explain the problem in more depth with @Erdayastronaut next week. This is a thorny issue indeed, given that vast resources have been applied to solve it, thus far to no avail.

Tim Dodd confirms Starbase tour to be filmed before IFT-4.

Starbase activities (2024-06-10):

• Overnight, three concrete pumps begin concrete pour for new tower. (morning photo)

• Parts for the CC8800-1 crane begin to arrive: 3 truckloads of counterweights arrive, followed shortly by a fourth, fifth, and sixth load.
• New raptor tracking diagram from Ringwatchers (tweet with updates).

IFT-4:

• Infrasound data from LabPadre, filtered and unfiltered.
• Elon replies to Marcus House with info on S29’s other three flaps: “Left flap also got very hot, but was less damaged. Rear flaps seemed to be ok, based on their control authority, but probably lost some tiles.”

Starbase activities (2024-06-05):

• S29 is restacked on B11. Video and photos from ViX, NSF 1, NSF 2, NSF 3, LabPadre, Mary, Starship Gazer 1, Starship Gazer 2, Cargile, Beyer, Ramirez, and SpaceX.
• Missing tiles on S29 have not been replaced (clwphoto1, ViX) and no decals are present on S29. The missing tiles are intentional, per Elon (cyb3rgam3r420 is one of his known alts).
• An igniter test is audible, and S29 flaps are tested.
• A possible concrete form for the 2nd launch tower base is delivered and unloaded. Zack chimes in with his thoughts.
