• 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?

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.

Starbase activities (2024-06-03):

• Build site: Early morning video tour. Ship lifting jig exits the Highbay. Barrel section moves from Starfactory to near Megabay 1. B15 aft 2 section spotted.

KSC:

• Tower segments and chopsticks still pending load onto barge.

Other:

• Christian Davenport: Barring any last-minute changes from SpaceX that the FAA would have to approve, the license should be ready for Starship's fourth launch attempt on Thursday, I'm told.
• New CSI Starbase video: Why SpaceX Plans To Jettison The Interstage On Flight 4
• IFT-4 infographic from BingoBoca.

• 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 (2024-06-01):

• S29 press plate is removed, and S29 is stacked on B11. Timelapse from ViX, photos from Starship Gazer, Mary, LabPadre, Doherty, cnunez, Ramirez 1 (raptor closeup), Ramirez 2.
• A couple tiles ~~fell~~ still off, but the vast majority are "OK".
• Workers test ship quick disconnect arm a couple of times.
• RGV Aerial spotted activity near Massey's on the Mexican side. Does SpaceX own any land there?

KSC:

• Chopsticks carriage and tower segment (#5) roll to the turning basin and are pending loading onto barge.

IFT-4:

• IFT-4 slips to Jun 6th.
• Elon: "The main goal of this mission is to get much deeper into the atmosphere during reentry, ideally through max heating."

Other:

• The @SpmtTracker account disappeared. Anyone know what happened?

Starbase activities (2024-05-31):

• Build site video tour: Fairly quiet.
• S29 aft flaps are extended. Chopsticks open.
• S29 moves between the chopsticks (which close and rise), and the LR11000 is laid horizontal. Closeups of the pad from Starship Gazer, NSF, Ramirez, and Doherty.
• Disassembly begins on the "GATEWAY TO MARS" sign. Starship Gazer closeup.
• Great photo of tower sections at Sanchez from RGV Aerial. We can clearly see four full-height sections and three 2/3-height sections.

KSC:

• Empty barge heading to KSC, likely for the two remaining tower segments.

Starbase activities (2024-05-30):

• Better video of S29 moving away from the tower the previous day.
• Overnight, B14.1 test tank moves to Massey's.
• LR11000 crane and continuous flight auger move away from the pad in preparation for IFT-4.
• Flight termination systems are installed on both S29 and B11 (photo, video)
• LN2 vapourizer is removed from the old orbital tank farm. Corresponding cryo pumps are removed as well.

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 (2024-05-29):

• SpaceX tweets some nice photos of the previous day's WDR, and confirms June 5th is still the target launch date.
• S29 destacked from B11 (Starship Gazer, Rover 2, Nerdle, NSF 1, NSF 2, NSF 3, Mary, cnunez).
• Stacking comparison from Elisar Priel.
• Workers in a lift remove a section of a chine on B11.
• S29 moves a short distance away from the tower.
• Workers observed on launch tower QD arm.
• Launch pad 2: RGV Aerial photo. Crane parts arrive (seven trucks, one truck), and the parts are assembled into an LTR 1220. Crane then begins moving rebar cages for the pile drill.
• Build site video tour: Parking garage construction progressing quickly.
• Road delay for booster transport still scheduled for May 30th 00:00 to 03:00.

Starbase activities (2024-05-28):

• Second WDR of S29 and B11: NSF livestream. Mary receives evac notice, klaxon and pad clear, detonation suppression system is activated, tank farm spools up, and LOX recondensers are venting.
• Chopsticks open (their arms wide), tower and launch mount start venting, stop, and start again. Chine vents are visible.
• Frost on ship and booster methane tank, frost on booster LOX tank. Nice wide shot of frost and venting.
• Full load, 30 minute hold, detonation suppression system is activated again, and depress vent.
• Deluge is activated (LabPadre, NSF, wide shot).
• Full timelapses of WDR (LabPadre, NSF).
• Chopsticks close (closeup (wide timelapse), and S29 flaps are tested.
• Concrete pump deploys at the former suborbital site, a concrete truck arrives, and concrete is poured.
• Road closures for May 29th and 30th are removed (hopefully due to good WDR), and new closures for Jun 5th, 6th, and 7th (00:00 to 14:00) have been added.
• New road delays (booster transport, 00:00 to 03:00) posted for May 30th or 31st. Likely to or from Massey's, B14 or B14.1.

Other:

• FAA determines that public safety was not in danger during IFT-3. Consequently, IFT-4 launch licence is not contingent on completion of IFT-3 mishap investigation.
