Apparently so. They scrapped SN12,13,14 in favour of 15, which has "
Same overall shape, just detailed and built better.

I just clicked on the live feed for a few seconds and they were talking about nozzle optimisation.

The Raptor engine is in continuous improvement (visibly so, from photos), but I don't think the nozzle has changed at all recently.

Any hints of launch time yet?

Sounds like it's off as they've cancelled the road closures.

Interesting. Will they be able to use GPS on the Moon or on Mars?

Don't think they're pointed in that direction. Also the relativistic corrections would be wrong because of the different planetary mass.

Nope. Not until those bodies have their own orbiting GPS (or rather, LunarPS and AreoPS).
Radar and radio beacons depolyed by earlier landings will be enough for early missions.

I wonder where the devices are positioned on the starship?
They have to work when it is flat and also when pointing up but coming down.

NASA Explores Upper Limits of Global Navigation Systems for Artemis - NASA
To support these ambitions, NASA navigation engineers from the Space Communications and Navigation (SCaN) program are developing a navigation architecture that will provide accurate and robust Position, Navigation, and Timing (PNT) services for the Artemis missions. Global Navigation Satellite...

Apparently some work has been done on picking up "spillover" GPS beams as far out as the moon. Accuracies of 200-300m are achievable, which can be improved by using multiple GNSS systems (GLOSNASS, Galileo, Baidu) or putting a handful of augmentation/authentication microsats in Lunar orbit.

Assuming that they have already thought of this, I imagine that there are probably antennas (at least) to cover multiple orientations.

This doesn't look great - a rocket tumbling in orbit and expected to have an uncontrolled reentry. Hopefully whatever bits survive reentry will land in the sea.

‘Out-of-control’ Chinese rocket falling to Earth could partially survive re-entry
Long March 5B is doing 27,600km/h in failing orbit, with eventual crash site unknown, after launching space station hub

Could be a big SpaceX day today, with two launches potentially within hours of each other.
At 20:01 UK time, there's another Starlink Falcon 9 launch - this being the first time a booster has flown 9 times.
At some point as early as 17:00 UK time (but probably later) it looks like Starship SN15 will take its first flight. Maybe they can land it this time?

Lovely orbit 2 pass seen in small binoculars from central London a few minutes ago. Upper stage very bright (mag +1), newly deployed stack running a fraction of a degree ahead all in a line apparently angled to the velocity vector (could make out 'structure'). Early in the pass they appear to be embedded in a diffuse cloud which might have been recently vented fuel, exhaust or sublimated ice particles. Spaced further apart in a quadrilateral encompassing all these were the rods, clearly tumbling (flashing).

Looking more hopeful now. On stream they're saying maybe another 30-60 minutes.

sorry.
it's much more informative than the official channel though. but if you're really into the countdown then yeah ^
