Here comes Booster 23. SpaceX is running two flows in parallel for Flights 15 and 16.
Starship Flight 16: Ship 43 has returned to the production site from its Pad 2 chopstick tests, with Booster 23 set to head out to Massey's for cryotesting.
This duo is expected to sail to KSC to be the first Starship flight from 39A.

So...we expected Ship 43 to go back to Production during tonight's first delay. But we had assumed the second delay, to Massey's, was just for a stand. We may have been wrong. Cuz that's Booster 23 in the doorway.

Ship 42 has completed both its single- and six-engine static fire tests, paving the way for Flight 15 in November. These events occurred during a busy period at Starbase that included Ship 43 testing ahead of Flight 16.

Ship 42 just wrapped a full 6-engine static fire at Massey’s, following its single-engine test yesterday.

New Dwarf Planet candidate!
Did we find a new dwarf planet?
@VRubinObs has revealed a new dwarf planet candidate that orbits our Sun beyond Pluto! And it may be among the largest and brightest objects discovered in this region of the Solar System: stanford.io/4exr85u
ALT This image shows the orbital pathway of newly discovered dwarf planet candidate 2026 ED138 (ED138), as observed by NSF–DOE Vera C. Rubin Observatory. This image is a composite of multiple images captured by Rubin between 4 March and 11 July 2026 at intervals indicated by the teal circles. ED138 is visible at the center of each circle. ED138 was found by Rubin Operations team member and in-Kind contributor Matthew Holman (Center for Astrophysics | Harvard & Smithsonian), who contributes to improving Rubin's algorithms that search for distant moving objects in our Solar System. Its distance from the Sun places it beyond the orbit of Pluto, and initial analysis indicates that it may be among the largest and brightest bodies scientists have discovered in this region of the Solar System.

‘Taking Flight’ (nearly). Our beautiful Artemis III Space Launch System (SLS) Core Stage left the surface of the earth (briefly) today as it ‘flew over the hump’ via a giant crane in the Vehicle Assembly Building to be mated between our 2 already assembled Solid Rocket Boosters on the Mobile Launcher. Spectacular job by our SLS, Exploration Ground Systems,and @NASAKennedy team! Go @NASAArtemis III!

Space freighters.
Scenes from this morning at the Kennedy Space Center turn basin, where NASA’s Pegasus and SpaceX’s Marmac 31 "You’ll Thank Me Later" barges are docked.
This is the first occasion they've been seen together in such close proximity, offering a rare opportunity to witness two vessels purpose-built to transport large spaceflight hardware.

A COPV appears to have RUDed at @SpaceX's McGregor facility at approximately 11:26:22 PM CT. @NASASpaceflight's live cameras watched as the stand became fully engulfed in the minutes after. (50x speed)

FIRE! SpaceX has conducted a single-engine static fire of Ship 42 at Massey's this evening. Is a full 6-engine test next in the cards?

It’s a beautiful day to set sail with the next pieces of Neutron flight hardware to Launch Complex 3.
Earlier today we sent Neutron’s Stage 2 and Thrust Module out of the Neutron Factory and onto a barge for transport through Chesapeake Bay to Wallops Island in Virginia.
Once it arrives, the Thrust Module will go straight onto the launch mount at LC-3 for check outs and the beginning of wider systems demonstrations including integrated fluids tests and module-to-launch-mount interface checkouts. With no strongback on the launch mount by design, Neutron’s Thrust Module is the rocket’s only physical interface to the launch pad, which this upcoming test campaign enables us to test early before the entire vehicle comes together.
