Quote from: Zed_Noir on 05/08/2022 10:27 amFor an expended center Falcon Heavy core. Can SpaceX stripped out the avionics and control units with command residing only in the upper stage like with legacy booster cores?This seems the wrong way to go.I worked in industrial equipment, not aerospace, but the non-recurring engineering costs were many orders of magnitude more than the unit cost (First working unit $100,000, each additional unit $10). Unless they are hand building wire wrap boards, I can't imagine this does not apply.Also, for something much smaller than a F9 I'd almost always run a couple of four wire CANbus between micro controllers than a discrete wiring harness as thick as your arm. Heck we'd use a CANbus for three or four collocated devices at a distance of a meter. Once you've got the processing to do the CANbus you've also got more processing power than the entire Apollo program essentially for free so there's nothing to strip out by moving software to a different box.

Side Booster B1064 was taken from Hangar X to Hangar LC-39A to be prepared for the launch of USSF-44.
NextSpaceFlight indicates that the launch is now scheduled for the last quarter of this year. [May 13]

Here's a dumb question that is becoming more relevant with each passing month: how long can Falcon Heavy's certifications for NatSec launches remain valid, given how long it is between actual demonstrated capability? Sure the hardware exists, as does the software. But institutional knowledge fades into the past; people get promoted, change roles or leave completely, and rarely-used procedures and skills grow rusty.

Now it appears to be the opposite so [USSF-67] will likely fly those side boosters as new boosters and then proceed with 52 and 44 reusing themHas the center core assignments changed for these missions?Not aware of that, not sure they would care about changing those since they're all expendable anyways

Sept. 1: [...] Adding month for Falcon Heavy/USSF 44
October Falcon Heavy • USSF 44
There will be quite delays in other launches due to this launch as:-1) pad 39a will be busy in conversion for launch , stacking and reconversion to normal. 2) after launch all east coast marine assets, that is, Bob/Doug/2 Tugs/ASOG/JRTI will be busy 2 solutions:-1) can spacex has rtls launches from slc-40 at that time like transporters 2) can vsfb allow high use with all starlinks of group-4 moved to vsfb at that timethey need to think otherwise 60 launches unachieved

It’s a mission to launch a satellite for the National Reconnaissance Office, which develops and manages spy satellites, according to a previous Space Force statement.https://www.bloomberg.com/news/articles/2022-08-11/spacex-cleared-to-loft-us-spy-satellites-using-reusable-boostersI would guess that the article might be referring to the future use of the side boosters used in this mission.SpaceX has three FH launches scheduled for the USSF (USSF-44, USSF-52 and USSF-67). At the moment it appears that this mission will actually be the first one of those three to launch, so one or both of the others could be using flight proven boosters.
