It looks like the FAA has closed out earlier today the Written Reevaluation of the 2022 PEA for Flight 5. This includes the larger sonic boom levels, the modified splashdown area for the hot-staging ring, and the use of the water deluge for the booster landing. Link at the end.
Looking through the document, this process was finished in the last couple of days with the Fish and Wildlife Service and the National Marine Fisheries Service ESA Interagency Cooperation Division signing off on the modified plan for Flight 5.
During the consultation period, the FAA requested the Fish and Wildlife Service to expedite the process and carry it out solely for the proposed Flight 5.
The FWS was concerned that the use of the expression "Flight 5 mission profile" would imply this concurrence was not just for this flight but also for flight 6 which is expected to use the same profile and vehicle configuration. They recommend certain measures before Flight 6.
The FAA replied back clarifying this and referencing the scope of the license.
In its concurrence, the FWS does agree that SpaceX could repeat launches using the Flight 5 profile, within the scope of the license, for up to five flights per year as has been the case for the current PEA which is being re-evaluated in this process.
The NMFS ESA Interagency Cooperation Division also signed off on the proposed plan for Flight 5.
According to the documentation, the new splashdown location for the hot-staging ring could be as close as 1km from the shore, although it is expected to be more in the 3 to 4 km distance. Previous reevaluation in Nov 2023 only covered 30-400km from shore.
I've stumbled upon so many comments recently claiming that Starship emits some crazy numbers of CO2 like some even saying it is 100,000 tonnes of CO2 that I really never understood where that's coming from.
Rant ahead...
Direct emissions from burning methane can't be that high because, well, the rocket has only 4,600 tonnes of propellant so it can't emit 21 times its own mass in CO2 unless you put a particle accelerator inside of it.
But the fun thing happens when you try and look up for the carbon footprint of extracting all of the consumables used on a Starship launch...
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)
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
For those keeping track, you may know that Ship 30 will sport a new set of antennas more similar to the ones on the booster so this confirms the observations. Ship 31 also has the same antenna design.
Falcon 9 made its first flight 14 years ago today🚀♥
📸 SpaceX
Long list of Falcon 9 milestones:
- June 4th 2010, first flight.
- December 8th 2010, first Falcon and Dragon flight.
- May 22nd 2012, Falcon 9 launches its first ISS-bound Dragon.
- September 29th 2013, Falcon 9 v1.1 debut flight and first propulsive landing attempt - 6th F9
- December 3rd 2013, First GTO mission (SES-8)
- April 8th 2014, First Falcon 9 with landing legs and first soft splashdown of a F9 booster (CRS-3)
- July 14th 2014, 10th Falcon 9 flight
- January 10th 2015, first droneship landing attempt (CRS-5, 14th F9)
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.
- 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
- Ship 24 will have onboard flight recorders to be retrieved for data. This we kinda guessed from the hardware installed on its exterior but now it's confirmed.
- A lot went into figuring out the impact to marine life due to Ship 24's impact with the water
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
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
And also, the release of these notices doesn't mean everything is ready, just that SpaceX hopes everything is ready by then which sounds like it is the same but it's different.
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.
