Booster 9 arrived to the OLM on June 20. If it static fires tomorrow - which all signs point to - then the time from arrival to static fire is 2 and a half weeks

Did some math and your idea is brilliant actually.

Lunar Starship is 1400 tons (1200 prop, 120 dry, 30 landing, 50 payload). Our “booster Starship” is, say, 100 tons dry. No heatshield, no nosecone, just a tank and some engines.
A total mass of 1500 tons (1400 + 100) with an isp of 375 seconds needs 500 tons of propellant to reach 1 km/s of delta V. That’s something like 5 tanker flights.

In our new scenario, a Lunar Starship launches and is filled with 1200 tons of prop from 8-12 tankers. The Booster Starship launches and is refueled with 500 tons of prop from 4-5 launches. It then pushes Lunar Starship into the 250X5500 km orbit, then returns to LEO with aerobraking. Do it slow enough, and you don’t need a heatshield.
This means a total of 12 (optimistic) to 17 (pessimistic) tankers are needed, as well as the Booster and Lunar launches. Neat.

The Booster Starship would probably just be a simple cylinder that latches into the rear of Lunar Starship, seeing as nose-docking is impossible with Vanilla Starships.

The Booster Starship would probably look like SN5

Hello few faggot. This is not new for the starship program. I know it might feel like that because this is the first hop you are following live, but it's always been like this, for every single starship test flight.

>The Federal Aviation Administration on Wednesday cleared a Temporary Flight Restriction for SpaceX’s Boca Chica, Texas launch site, putting the company on track to proceed with a critical test of its newest Starship prototype this weekend.
>However, the TFR was later retracted on Thursday. The Starship prototype is now expected to launch on Monday, December 7, pending final approval from the FAA.
