Is it just my eyes or is the booster noncircular on that diagram? The arrangement looks like an ellipse.

It's not your eyes. It's wonky on their graphics, but looks normal on SpaceX's original.

Here's one of the new Raptors (Number 72) recently delivered to Mos Eisley. I mean Boca Chica. I mean Starbase.



Also delivered was number 74 "Plaid Mode".

And here they are:



Doesn’t look like SN16 will ever get to fly though. The partially built SN17 has already been scrapped. They’re concentrating on the booster and SN20 now. They obviously feel they learned enough from SN15’s flight to skip to the next iteration.

SN15 and 16 will make a nice backdrop to Elon’s presentation, which is supposed to be happening sometime. I expect after the big test flight in July.
The one on the right, which I think is SN16 is missing the fairing at the front of the tail flap pivot, so either they've decided the fairing is unnecessary or they're putting no more effort into getting it flight ready, which supports the "will never fly" hypothesis.

Musk has stated on Twitter that they may do hypersonic flight tests with SN16

The next Falcon 9 launch is scheduled for 7.56 pm UK time on Friday 25th June from SLC-40 at Cape Canaveral.

This is the Transporter-2 mission with lots of small sats onboard. The previous Transporter-1 mission back in January set the record for the number of satellites deployed in one flight (143).

This would be a good one to watch in person for anyone in the area. The rocket will dog leg southward after launch. The plan is to for the booster to head back and land back at the Cape at LZ-1. The first time that has happened for a while.

The booster number is B1060 and this will be its 8th flight.

Do you mean watch online or will it be visible from the UK?

I mean if you're in the central Florida area it would be a good one to drive over and watch. You’ll get a launch and landing for your troubles. The Port Canaveral area to the south would be a good viewpoint.

It won’t be visible from the UK, but it should be a good livestream to watch.

The Falcon 9 for tomorrow's Transporter 2 mission is going to do some fancy gymnastics:



The red lines are engine burns.The booster will backflip and land to the south at LZ-1. The upper stage will skirt the Florida coast to the south.

Meanwhile landing ship Of Course I Still Love You is onboard carrier ship Mighty Servant 1 off Panama. They're awaiting permission to begin transiting the Panama Canal.




It looks like the new east coast landing ship, A Shortfall of Gravitas, is now ready. One of the tugs has left Port Canaveral heading to Louisiana to go and collect it.

The Transporter 2 launch has been delayed for now. No official word on a new date yet.


The OCISLY landing ship is now being carried through the Panama Canal:

I'm rather pleased they've kept to a mostly common architectural style for the canal's expansion locks. The various original buildings within the canal zone are pretty consistent in appearance, and I'm glad they've chosen to keep using it.

Unlike their rejection of the mules for tending the lines, I'd argue they're as much a part of the canal's character; the move to tugs only was rather disappointing.

Having watched mule operators juggling line tension as they move up/down the slopes by the lock gates, I suspect that it's much easier to get/train tug crews.

The more I've learnt about the canal, the more it has impressed me as a piece of engineering.

I read it a few weeks ago, it’s a nice insight into how things were.

Indeed. It's amazing how close they came to not existing at all. Also strange just what risks they took. And how they have burned out people.

I got that book recently as well. It fills in a lot of details of those early days. Kinda skates over the last 10 years, which is fine, but there’s definitely scope for a follow up book.

The first vacuum optimised Raptor engine has arrive at Boca Chica:



Asked if this was for Starship SN20, Elon replied:

"It is! Looks like we can get 378 sec Isp with this version of Raptor Vacuum, so over 380 sec with some improvements down the road."


It's Elon's 50th birthday today, so happy birthday to him. party

Do the hot gas thrusters actually ignite the hot gas? Or are they just called that because they aren't from nitrogen tanks?

Burn it for more thrust, basically a mini rocket motor.

Supposedly Methalox same as the Raptors.
