Looks like a very clean interface.

• Pad 1: The concrete pour for the flame trench centre floor is completed. 250+ truckloads were delivered over the course of 16 hours. (ViX, TrackingTheSB, lewisknaggs42)
• Some cladding is installed near the top of Tower 1. (ViX, ViX 2)
• Pad 2: A chopstick actuator is removed. (ViX)
• A deluge test is observed. (TrackingTheSB, RGV Aerial)
• Other: 51 foundation footings are now visible at the new 444-acre site along Highway 4 near Starbase. (RGV Aerial photo, RGV Aerial video)
• S40 recovery: Forte passes the tip of South Africa. (marinetraffic.com)
• Flight 14: Earliest launch windows are now Sep 22nd and 23rd, both 12:15 to 14:14 UTC (07:15 to 09:14 local). (fly.faa.gov, archive, Avid Space)
• Elon confirms no ship catch for this flight. (outerspacetoday)

AVUM+ boost 4 shutdown confirmed, nominal orbit, and separation of FLEX confirmed. Mission success.

Sentinel-3C separation confirmed. Nominal orbit.

AVUM+ boost 2 shutdown confirmed. Nominal orbit.

Starlab? I guess that is the one with the most ESA buy-in through Airbus.

At this point I just hope someone gets something up and operational before the ISS retires. Seems like Vast will probably be first to get a module launched.

• 2027 Q1: Vast Haven-1
• 2027: Orbital Reef (contingent on Vulcan and/or New Glenn return to flight)
• 2028: Axiom Station
• 2028: Vast Haven-2
• 2028: Bharatiya Antariksh Station
• 2028: Russian Orbital Station (LOL, eat my hat Peter-Beck-style if this schedule holds)
• 2029: Starlab (contingent on Starship Cargo variant)

These timelines are getting kind of close to ISS retirement, and we haven’t really seen hardware from anyone other than Vast and Axiom.

AVUM+ boost 1 completed. Nominal parking orbit.

AVUM+ startup confirmed.

Zefiro 9 burnout stage separation confirmed.

Zefiro burnout, stage separation, Zefiro 9 ignition, and fairing separation confirmed.

LIftoff!

Orbital parameters from Jonathan McDowell: https://bsky.app/profile/planet4589.bsky.social/post/3mvjahteb5s22

The three O3b satellites launched yesterday have been cataloged in a 300 x 6660 km x 16.9 deg transfer orbit. Final target orbit is 8055 x 8075 km x 0.0 deg.

FLEX go no-go poll is complete. They are go for launch.

Sentinel-3C and Vega systems are also currently go for launch.
