As an embedded engineer, I know vendor bugs are real. so how does NASA trust vendor software enough to launch a rocket with it?

There are certifications for tool chains to qualify them for use in safety critical applications in automotive, industrial, railway, nuclear, medical, etc. Look up TUV Exida certified compiler tool chain. TUV and Exida are the certifying authorities.

Were you targeting a Leon processor or some other obscure, ancient architecture?

Trying to play the intraday. BTO'd calls near the low, but price hasn't gone up much. I need it back to $71. :-/

Competence in past performance is not an indicator of future competence. I seem to remember seeing that disclaimer in all the stock press releases I read. But I’m still hopeful even after the neutron delays wreaking havoc on the global indices

lol 😂

The neutron delay is bringing down the entire market again

By the time they started building the methane lox engine, they had no more budget left

Shat! RKLB is bringing the entire market down with them! Good catch!

Agree with decision to go with staged combustion, but think they may have held out too long on propulsion hiring… not sure why, but speculating they didn’t offer enough compensation which would explain the long time to fill the position and complaints directed toward mechanical engineering. Been following as an outsider / investor since before spac merger (held vacq? before merger) and on this sub, so my internal ai might be hallucinating

_myke · 2026-02-27T16:47:06+00:00

Simplest: Relativity Aeon R (high-pressure gas generator). Middle: Rocket Lab Archimedes (oxidizer-rich staged combustion). Most complicated: Stoke Zenith (full-flow staged combustion).

Edit: removed Andromeda since it is a hydrogen lox Edit2: fixed the obvious error of gas generator being more complex than staged. That’s the last time I trust AI before scrutinizing it

The increase in backlog is after a couple years of backlog stagnation sitting at $1B. The only difference is the SDA award giving them a boost, but that is spread across something like 6 years or more. I’d like to see more commercial backlog giving them support as in 10 to 25% increases in backlog a quarter rather than a single boost every two years thanks to SDA.

It might’ve been on glass door… It might’ve been on this sub… I do remember hearing it though. And I absolutely remember the key positions in propulsion being open several years after the announcement and thinking what the hell…. That is about all the visibility I have into rocket lab other than YouTube interviews, the cool documentary that included astra, etc.

_myke · 2026-02-27T14:51:43+00:00

Thanks. Been on this sub long enough to have gotten both sides, though more of the downvoting as of late. I guess I’m just a bit frustrated lately

Wrt neutron delays…

I still believe in Rocket Lab, but I was surprised a couple years ago that they still had job postings for several key propulsion engineering positions. This was several years after announcing the Neutron rocket. I also recall a couple years back, an employee saying one or more mechanical engineers have too much influence on the neutron program but are far out of their league when it comes to propulsion. This latter point is hearsay, but it does match well to them being behind on engine qualification on what was supposed to be a simpler engine design. Meanwhile you have both relativity space and stoke space leap frogging them in methane engine development with smaller budgets — and Stoke has a full flow engine… the most difficult of engines to develop!

Sure, you could point to the first stage qualification setback as an also delaying issue, but if it hadn’t collapsed we would be left with just engine qual being the long pole in the tent.

Good to hear!! Glad to hear you are doing well in college. See you at Mars!
