Watch any of last year's SpaceX LEO satellite deployment missions's broadcasts in YouTube, and you can see views from at least several different cameras. At least two on the 2nd stage nozzle, at least one on the payload, at least one on a gridded fin, one in the 2nd stage LOX tank, and I suspect there are many more.

The cameras serve several purposes, possibly including marketing and HR/recruiting, but primarily they are used to collect additional information about the flight.

Question: Roughly how many self-viewing cameras are present in a Falcon 9 LEO mission?

Details may be confidential or proprietary, but are there closer to a dozen or a hundred? Closer on a log scale or linear?

  • $\begingroup$ The Iridium-1 mission demonstrated that the downwards looking camera on the first stage can broadcast all the way down to landing on the ASDS. $\endgroup$ – geoffc Feb 3 '17 at 15:55
