Ship 42 is setting up for a single-engine static fire shortly. Ship 43 is practising what it's like to be caught. youtube.com/live/t8RZHIfgQ3A

Rocket Lab
@RocketLab4h
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.

@AmazonLeo7h
Leo Vulcan 1 (LV-01) payload on the move. LV-01 is the first of 38 Leo missions on @ulalaunch’s heavy-lift Vulcan rocket, and last week, teams successfully transported the 40-satellite payload—encapsulated inside a 70-foot-tall fairing—to the new Amazon Vertical Integration Facility (VIF-A) at Cape Canaveral.

‘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!

En esta foto mucho de de dónde venimos y mucho de hacia dónde queremos ir. Pedro abrió el camino para los astronautas españoles, Chrsitina representa el brillante presente del espacio y Sara y yo tenemos la suerte y la responsabilidad de coger su testigo. Qué alegría compartir una noche así en los Premios Princesa de Asturias, acompañando a Christina mientras recogía su premio a la Concordia.

NASA's Kennedy Space Center

Big move, bigger mission! The Artemis III Space Launch System core stage moved to the transfer aisle at NASA Kennedy. Next up – teams will lift and integrate the massive 212-foot-rocket with the solid rocket boosters as we prepare for the next giant leap in lunar exploration.
The SLS (Space Launch System) core stage is horizontal in the transfer aisle of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Friday, Oct. 23, 2026. The 212-foot rocket stage was lifted from High Bay 2 using a one-of-a kind lifting beam designed to lift the stage and will be joined vertically with the completed solid rocket booster motor segments in its short stack configuration.

Ship 43 is on its way back from Massey’s, and Ship 42 is rolling in to take its place - all while Booster 22 is being lifted off Pad 2 after its static fire. Never a dull moment at Starbase. Watch tonight’s triple header live: nsf.live/starbase @NASASpaceflight

So I guess two rolls tonight wasn't enough? Now that Booster 22 is off the OLM, there is ANOTHER delay tonight for it to roll back to the barn. Ship 43 is back at Production now, and Ship 42 is likely to leave soon. 🎥: nsf.live/starbase | @NASASpaceflight
