1. NASA also made design changes like adding mass dampeners to the rocket to reduce the pogo oscillations (although I don't think the hardware was actually built before the program was canceled).
2. The fix described in the article definitely cost more than $5. The ICs might've cost <$100, but I wouldn't be surprised if the cost of the fix was six or seven figures after taking into account the design, installation, and QA steps
- alhirzel 4y agoAdding water to something (dampening mass) is less effective than adding something solid to it (damping mass). One of my favorite little pet peeve typos...
- Baeocystin 4y agoHuh. TIL. Do you know the reason for distinguishing between the two in this way?
- LarryMullins 4y agoIt's a play on words, to "dampen" something is to make it moist.
- Baeocystin 4y agoWelp. That's what I get for commenting before coffee!
- Rebelgecko 4y agoThanks for the correction! Have you seen the designs for interplanetary spaceships that use the crew's water supply as a protective shield to block radiation? I wonder if they need mass dampers for their dampening mass.
- just_boost_it 4y agoIt's like saying that software built using an open source languages and libraries was built for free.
