For the first time in history, you can hear what a 2nd stage sounds like with our new live audio from space. We use structure born vibe to recreate audio. Listen for stage sep, electric pumps spool up and ignition. Pretty cool!

      Yes, such a cool addition to have space audio! Presumably there is a technical reason it’s worthwhile as well? Does it help with troubleshooting engine issues or something?

        More data are always better. Back in 2015, the Falcon 9 engineers used acoustic triangulation to identify the specific strut which caused the CRS-7 failure. You never know which data might end up being useful, or even crucial…

          Yeah I assumed it wasn’t just for the gimmick. Really cool about using the acoustic triangulation to identify the issue.

          So SpaceX are already using microphones/vibration sensors so could have done the audio reproduction that RocketLab have done here?

            I can’t find a primary source for this, but I believe acoustic triangulation SpaceX did used accelerometer data, not microphones. I’m not sure the accelerometers would have had a high enough sampling rate to reproduce audio like RocketLab have shared here.

              Ah I see. So RocketLab might be taking it a step further and putting more sensitive sensors on in the hope the additional data might help, with a secondary benefit being the PR from being able to reproduce audio from space.
