Neutron | Stage 2 Cryogenic Test

In October 2023 we completed cryogenic testing for a Neutron 2nd stage. This crucial test involved filling the tank with liquid nitrogen & pressurizing it to expected flight pressures, then pushing it all the way to failure to test extreme tolerances.

As part of structural testing we push our tanks to Maximum Expected Operating Pressure (MEOP)...and far beyond.

Stage 2 looks bigger than I expected. Let's go Neutron!!

I'm really excited to see the progress of the Neutron. Let's go Rocket Lab!!! Greetings from ARG!!

That was a perfect failure. It looks like the tank exploded really evenly, which would indicate that there are no obvious weak spots and that they have got the manufacturing process down. Really exciting!!🎉

Thanks for showing us the fun! I look forward to Neutron very much.

Awesome ! Thank you for giving this videos, it's awesome to be able to see the evolution :D
I can't wait to see what is next, keep it up !

[drds]

Looking great! I am glad the testing seems to be going well!

[ptonpc]

Ah, that'll polish out :D Great to see the progress!

[daniva]

Great job guys. We're waiting to see the whole beast soon

[SebastianWellsTL]

Great to see the progress you have made so far, and I am super excited to see what's next! Congratulations on a successful test!

Go Rocket Lab! Go Neutron!
Can't wait to see an engine test!

Triple checked my audio setup before realizing that there is no sound at all ... Looking forward to further tests

"...and far beyond" awesome!

Number 8 wire at its best!
To watch live, that would make a fantastic finale for a school science

Knowing just how far it can be pushed, and from that how large the safety margin is, is data that is worth the cost of destructive testing.

This is the 2nd stage tank!
Neutron is going to be much bigger than I imagined.

😀👍🏼

Thanks for showing us the test. Good luck.

Nothing better than learning from explosions!

Structural tests like these are required by everyone, so it is nothing like SpaceX, instead, it appeared to pass the first time which highlights first-time quality engineering. Well done Rocket Lab for great engineering :)

[TheSpaceflightGuy]

WOAH! Nice test to falure! It was a succesful failure! Lots of important data learned :)

There was an earth shattering kaboom that'll make some people very happy
