Neutron testing continues at our Space Structures Complex in Middle River with the interstage on the test stand ready for its qualification campaign. We're running a series of static load tests and applying ~1,000 tonnes of force to simulate flight loads on the way to orbit.

Neutron's interstage has to withstand not only the rigors of launch, but also reentry as it remains attached to the vehicle's first stage and Hungry Hippo fairing, landing back on Earth as one integrated structure ready for the next launch.

And here it is outside!

Thank you Rocket Lab - this is the kind of detailed updates us curious cats love to see.

Thanks for the update 🙏 - exciting times.

Thank you for taking us along each step of the way!

I can’t wait to see this baby fly!

1000 tonnes of force is still less pressure than trying to type your password while someone is watching you

Identified an Issue, The hook directly connected to two slings, which creates side loading on the hook. hooks must maintain 100% vertical load orientation. Method: Hook → Master Link → Two Slings → Two Shackles This configuration keeps the hook under pure vertical tension.

That's crazy that it can handle 1,000 tonnes of force.

@SpaceIntel101 The carbon fiber looks so much cleaner than the first piece.

Neutron is alive 😃😃😃

How on earth do they even make something like that? The more I look, the more impressive it gets.

👏 Neutron gettin closer

It’s beautiful!!!

That load figure is wild—simulating 1,000 tonnes of force really puts the "medium-lift" capabilities into perspective. Great to see the interstage hardware actually on the stand and taking punishment. The road to orbit is paved with these exact kinds of stress tests.

Thank you 😊

Still testing means more delay … Q2 confirmed.. rest depends on further posts

Thank you for share with us. This rocket will be amazing

Beautiful 😍 Well done Team!!! Keep winning!!!

Our little rocket 🚀 co growing up fast!

Interesting problem. If I understand correctly, this is effectively the cargo bay, and therefore can’t have any internal bracing. All the strength needs to be in the tube. Even small manufacturing weaknesses or faults could prove disastrous. Good Luck!

Omg 😱😍 1000 tonnes

Let’s go!!! To the Stars!!!

@Blobifie Beautiful. Can they please look into this concept? Carbon fiber frame. Covered by spiral wound sheet, helical weld, cover weld with strip and double weld. So much stronger. Outside, robotic, safe, precise, fast.

How will you transport the completed stages between Middle River and Wallops? I would assume water, but there doesn't seem to be a suitable wharf near your new factory.

Gooood

Can I assist you or may I help or give insight

Go you good thing!

Neutron testing continues at the Space Structures Complex in Middle River. Interstage on the test stand is ready for its qualification campaign — static load tests pushing ~1,000 tonnes to simulate flight loads en route to orbit.

Make it strong 💪

Goodddd luck yall!!!! So excited
