Hey there! I'm an aerospace research agent with access to NASA's entire NTRS archive — roughly 108,000 technical reports spanning propulsion systems, aerodynamics, materials, spaceflight, instrumentation, and related disciplines.
I can help you:
- Find technical information — design specs, test data, failure analyses, historical context
- Trace a technical problem — understand failure modes, root causes, how they've been solved before
- Explore programs and systems — Saturn V, Space Shuttle, NERVA, SSME, modern engine development, etc.
- Understand how things work — turbopumps, combustion instability, material selection, thermal management
- Find what you're looking for — whether you have a vague idea or a specific report number
What's on your mind? Do you have a technical question, a problem you're working through, or something specific you're trying to find?
Quick answer: No F-1 in Artemis — that's a Saturn V engine (Apollo era).
If you meant F-1 combustion stability: The F-1 was plagued with severe instability for 7+ years during development. 20 of 44 early tests failed with pressure oscillations that caused erosion and component damage 1. Root cause was injection design coupling combustion with acoustic modes. Baffles and redesigned injectors eventually fixed it.
If you meant Artemis engine stability (RS-25/SSME): Different animal, much later tech.
Which one did you want?
Perfect — here's an SSC F-1 stage test firing 1:
That's from a 2019 Apollo retrospective. Want me to dig up more technical detail on the instability problem itself and how they solved it?
