I'm a little confused - it almost looks like methane is bleed off of the main combustion chamber and then merged with the oxidizer? Or is that the methane used as a coolant around the nozzle and then recovered and burned?
I've never looked into rocket nozzle designs; is that a typical arrangement for engines that use cryogenic fuel?
Due RP-1 designs use the oxidizer the same way?
Because of this, the French and Italian ministers are calling for Europe to offer a significant "technological and industrial" response to the rise of SpaceX. It is not clear what form this would take, nor how quickly the European nations could move in response.

Dragon XL will be used to resupply Gateway, a lunar outpost for Artemis astronauts. This resupply ship will also include a toilet and beds to provide extra space in HALO for science.
If any of you wondered why there is a grapple fixture mounted on the side of Dragon XL, that is because Canadarm 3 can only reach the external payloads, on the back end of Dragon XL, by walking off the Lunar Gateway and onto Dragon XL.
From that position Canadarm 3 will move the external payloads to temporary mounting locations on Gateway exterior.
SpaceX will conduct a second static fire test after one of three Raptor engines on Starship SN11 had to be removed for repairs. The static fire could occur as soon as Friday, pending Raptor readiness and road closures.

Drat. Exploded again.
If you are an US amateur of French spirits and Italian cheese, I would suggest you start stocking:

The Falcon 9 has come to dominate commercial satellite launches.arstechnica.com
As the newspaper reports, Europe now lags behind SpaceX in other key ways. Because of its partnership with NASA, SpaceX can now launch astronauts. French astronaut Thomas Pesquet, in fact, is a mission specialist on the Crew-2 mission due to launch next month. He will likely be the first of many European astronauts to reach space on a SpaceX vehicle.

You have duplicate posts that are the same from 22 to 23 minutes ago, just so you know(in case its an issue for moderators and such).now that is very disturbing News
According NWS Brownsville Radar
