Peter Beck got caught lying being dishonest:

https://twitter.com/esuse09/status/1828826956961595726

Quote from: Erik S (likely Erik Susemichel, SpaceX Director of Commercial Launch Sales)
Quote from: Peter Beck
This is why our customers fly on Electron, orbital elements are provided immediately after separation with extremely high accuracy. Nobody should ever have to go looking for their spacecraft.

To be clear, we also deliver extremely high accuracy orbital elements within minutes of spacecraft separation (pending telemetry coverage). The expedience of delivery of orbital data is not an Electron differentiator.

So I guess Jonathan McDowell would be the real "liar," then? He's the one who said "This is an ongoing problem with these rideshare launches:  long delays in getting orbit data, leading to inability to contact the satellite  during the first month of life, which all too often leads to loss of mission. Really needs to be addressed." Which is what Peter replied to (making it clear that Peter was specifically comparing with orbital elements from Transporter missions, not dedicated Falcon 9 rides).

A couple of follow-up tweets from Jonathan, with a bit more context:

https://twitter.com/planet4589/status/1828459468935569854

Quote from: Jonathan McDowell
Quote
Could spacex provide initial orbital data using starlink? They will doing an in space laser communication test very soon so that might become possible?
They do provide initial data, but after 10 days that data is no longer useful

https://twitter.com/planet4589/status/1828459724809101436

Quote from: Jonathan McDowell

would using individual payload delivery from a small lift rocket provider aid this, or am i misunderstanding
Yes - this is an advantage of doing a  single-payload or few-payload launch on a small rocket like Electron. Much easier to ID the objects and get individual orbital data

So it seems like this is less an issue about delivering the initial orbital elements, and more an issue of tracking the payload over the following days, so those orbital elements can be updated.

(edited to turn x links into twitter links, so they would appear properly on desktop)

If you have a cloud of many tens of small objects all floating vaguely close to each other, in unknown orientations, some manoeuvring (with no central coordination) then even if you have an accurate TLE at time of release, it is nontrivial to tell which of those many different objects is your object until you wait long enough for them to drift into distinctly separate orbits allowing you to try and contact them one by one until you hit yours. Meanwhile, everyone else on that launch is trying to do the same thing, so everyone is shouting up a big RF soup, and everyone who can manoeuvre is doing so so you can't even narrow down much by going "that one is ours, because it just moved". Assuming your satellite is also talking on RF and able to move in the first place - if there is an issue, it takes even longer just to pin down where your satellite is before you can start troubleshooting.

The joys of rideshare, you get what you pay for. Space tugs should help here. NB Curie kick stage is basically space tug.

If the upper stage had endurance though, why not simply deploy at a slower pace? Wouldn't that provide enough separation to make the train of sats more identifiable?

Not at all, as your later post shows, Jonathan McDowell admits that SpaceX does provide orbital elements immediately after separation, he was talking about orbit data from Space Force several days after launch. Peter Beck chose to interpret McDowell's tweet to mean something else, that's on him.

McDowell also clarified later that this is not a SpaceX problem, it's due to many smallsats don't have GPS thus cannot get their position on their own:

It's possible that Peter Beck misinterpreted Jonathan McDowell's tweet in the same way I did. Jumping to saying he was "lying being dishonest," as you did, seems rather unfair.

Not even a misinterpretation.

Original claim:
https://x.com/planet4589/status/1828424214455452070
Quote
So two problems: flaky power supply and bad TLEs.
The latter is understandable; the Transporter 11 payloads have not yet been cataloged by Space Force so they are presumably relying on SpaceX's post-deployment states, which are pretty stale after 11 days.
[...]
This is an ongoing problem with these rideshare launches:  long delays in getting orbit data, leading to inability to contact the satellite  during the first month of life, which all too often leads to loss of mission. Really needs to be addressed.

The quote from the SpaceXer that SpaceX provide TLEs on separation for Transporter missions is thus a 'not even news' rather than some gotcha or refutation. Likewise, Beck was just confirming that dedicated smallsat launches do indeed aid in orbit identification in practice.

Well I'm assuming Peter Beck would know what his main competitor is offering, or at least by reasoning from first principles would understand this service is something pretty easy to provide, so there's no reason for SpaceX not to provide it.

If he truly doesn't know, then instead of "lying being dishonest", this means he's rather careless when tweeting stuff that is material to the business and shows a lack of awareness of the main competition.

When you deploy a satellite it's orbit will be very close to that of the upper stage.  If you wait a while it will still be very close to the upper stage and the next deployment.

Either the deployments would need to be energetic, or the upper stage would need to maneuver between releases to get separation.

If it's a problem that needs solving, it's probably easier to solve by standardizing RF protocols.  Perhaps using something like the secondary radar transponders used by aircraft.

Space Structures Complex

Quote
Rocket Lab's Space Structures Complex in Middle River, Maryland, supports the automated production of all large composite structures of the Neutron launch vehicle including the panels that make up the 91 ft (28 meter) length interstage and fairing, 22.9 ft (7 meter) diameter first stage, and the 16.4 ft (5 meter) diameter second stage tank. The site is home to the world's largest AFP machine of its kind, a 90-tonne autonomous machine expected to save around 150,000 manufacturing hours in the Neutron rocket's production process.

Surely SpaceX's 9m BFR Mandrel or 12m ITS tank were larger?

Did SpaceX use AFP for those? Since they were very early into exploring carbon composite structures, it's possible they used manual fiber layup. And the Rocket Lab tweet doesn't say anything about the largest carbon fiber parts or tanks, just the largest AFP machine.

Since the old Martin facility is already set up for loading stages onto barges, presumably Rocketlab will be having their recovery barge pull double-duty to transport these from Middle River out through Chesapeake bay and around to Wallops to unload at their future dock, same as they would for downrange recoveries.
Either that, or they only intend to ever use Middle River for laying up individual panels and domes, and all integration will occur in the big tent at Causeway Rd. That seems like a lot of extra effort to maintain two nearby but still separated facilities to perform the job of one, and Middle River has gotten the hard-to-move-at-a-late-date equipment.

I remember that guy during my investment in Rivian. They had tough productions due to various shortages after lockdowns across the globe. Unable to source parts to keep line going. This guy came in during those critical hours, start scaling up, and start adding extra shift. Very interesting times.

Magna Steyr, they produce Daimlers and is contractor for automobiles makers. I heard that some series are exclusively produced by them. I came across this company when I used to do my research on automotive industry.

Which makes me very curious, why Sir Peter Beck would want someone with such manufacturing expertise to helm the company operations? It is not like they are doing mass productions. I do understood that Sir Peter Beck has manufacturing experience in precision parts back in those days, but I can't really see the connection. Not like the company is building some lunar rovers in massive scale.
