While we wait for SpaceX to de-stack Ship 40 and roll back booster 20 for engine swaps and other checks following yesterdays abort right at engine ignition, I thought I’d share my close encounter of Ship 40 as it rolled to the launch site a few days ago. If...

Just 8 days after the final stack of Superheavy-B16. B17's common dome section has been moved to the front of MB1 for stacking operations. As expected, the pace of vehicle assembly will have to increase dramatically in order to keep up with SpaceX's goals for Starship Launch Cadence in 2025. We are rapidly approaching Flight 7, and Booster 17 is the Flight 10 Booster. Assuming SpaceX plans to carry out 20 to 25 launches in 2025, this booster will need to be fully stacked, cryo tested, integrated with its 33 raptor engines, static fire tested, and receive final launch outfitting 8 to 10 weeks from today. To date, the record holder for fastest assembly to launch time is B13 which took 41 weeks from initial stacking to launch. This means the assembly and test campaign for B17 needs to be at least 4 times faster than the previous best (assuming there are no re-flights's of boosters within the next 4 launches). If every booster from here on has one re-flight before B17's inaugural launch, then the assembly to launch process only needs to be around 2 times faster than the current best. I should note that B14 is expected to be the new record holder. If it launches on Jan 10 it will have been just under 40 weeks. Another important detail is that from what we can tell, this a Version 1 Booster. This means that we should expect a minimum of 4 more launches before Pad B is operational. One thing is for sure 2025 is going to be WILD!!! Shoutout to The Ringwatchers discord server for helping me gather the required data on such short notice. Make sure to follow them if you haven't already.

Here's Elon Musk in 2013, explaining SpaceX's plan to build a commercial spaceport in Texas, which would later become Starbase. “Cape Canaveral is good for eastward launches. Vandenberg for southerly launches. And we figure we need a third launch site that's a commercial launch site. Because Cape Canaveral and Vandenberg are Air Force bases which is cool, and obviously, there's an important need for Air Force space launch bases, as there is for Air Force airports. But there's also a need for commercial airports. Just like you wouldn't expect commercial airliners to land at an Air Force base at a normal course of events, it makes sense to have a commercial spaceport. We need to be able to launch eastward. And we want to be close to the Equator. That basically means the potential states are Virginia through Texas, going south, Hawaii and Puerto Rico. We need to stay on US territory, because rocket technology is considered an advanced weapons technology, so it's very difficult to export that to other countries. So, those are our options. Right now, Texas is arguably the leading candidate. But we need certain legislation passed that's supportive of space launch. I don't think it's particularly controversial, but one of the things we need is we need is to be able to close the beach when we're doing a launch. And Texas has the Open Beaches Act. We can't launch if there's someone right next to the rocket on the beach. Like I said, I don't think it's a particularly controversial thing. It's pretty straightforward. Then, we need a little bit of protection for the-1-in-10,000-person case who complains about the thing. We had this dude who filed a lawsuit against us for our rocket development site in Central Texas, near Waco. He's not even in the same county. He's in a neighboring county. And he also thinks the CIA is listening to his brainwaves. So, we need just a little bit of protection for people like that, so we're not spending a ton of time in court. That's basically what we're asking for. It's nothing major, and I think it's likely to move forward. If things go well, there'd be a decision this year, and then we'd start construction next year. And then, probably, the first launches would take place from there in two to three years.” SXSW, March 09, 2013
