SpaceX applied yesterday for a communications permit for Starship's next flight. As expected, SpaceX leaves the possibility for this mission to feature a booster catch. However... there's more information attached to this that's very interesting.

Here's a🧵(links at the end)

Image SpaceX added an exhibit for this permit explaining why this permit has additional communication frequencies for the Ship. It indicates that this flight and the next (5 and 6) will feature a similar set of radio controllers as to the ones we've seen on the Booster Image

Welp I was going to sleep but instead spent about an hour reading through this 122 page PDF that came out today along with the license. This is a re-evaluation of the PEA specific for the flight profile of the first few flights of Starship, cool stuff.

faa.gov/media/27236 Image Some of the stuff that I found interesting:

- Second and Third flights of Starship will be with S26 and S27 (expected but now comfirmed)

- Super Heavy will be landing on the surface of the ocean. SpaceX will NOT recover it and will instead try to sink it in any way possible ImageImage

It appears that the marine notices for Starship’s first orbital flight have been released!

The daily windows run from April 6th to April 12th and are open from 7:55AM CDT until 12:10PM CDT.

A reminder that this is, of course, pending the FAA’s launch license and other closures Marine hazard notice for launch out of StarbaseMap representing the hazard zones for notice 372/23 NAVAREA Splashdown notice for Starship orbital flight As I mentioned in the NSF stream for Ship 24 rollout () this is just the FIRST set of marine notices. As the vehicles come together for launch preps and final paperwork is readied, it's likely these will get cancelled and new ones will go out for later days

Based on marine exclusion zones the next possible attempt would be on April 3rd but that will depend on SpaceX solving the issue that led to the abort yesterday on time for that opportunity. Looks like we will have to wait for another month to do this 😅

I've seen a lot of people complaining that the Starbase PEA only sees a cadence of 5 launches a year from there and some people even think this will never ever allow SpaceX to complete their HLS contract so Jeff Bezos must be super super happy about it.

Here goes a🧵 There's something all are missing: Comparison. What did it look like for Falcon 9's first EA? Well...

"The goal is to launch up to six Falcon 1 vehicles and up to six Falcon 9 vehicles per year starting in 2008, with the goal of achieving up to 12 launches per vehicle."
