Don't get me wrong, it's a space ship so of course it's incredibly exciting and no doubt also a career highlight to work on! :)

Just sayin', the OTA part is fairly mundane implementation-wise, flipping bits. The decision to engineer a system around it and have it in the requirements is maybe more audacious. Also, the technology involved with us still being able to radio into these remore devices at all is amazing and the unsung hero here.

Edit: If you go to the FSW section here, you can read a little bit of what amounts to release notes for the onboard software changes:

Includes a cute anecdote about dealing with a randomly flipped bit in memory.

My favorite bit:

"A CCS FSW patch was developed and implemented in 1995, and linked on the spacecraft in 2006 for V1 and 2005 for V2 to automatically restart some of the critical functions in the event of an Error entry. This patch was exercised in flight in 2014, nearly 20 years after it was installed, when one of the CCS processors went into an error entry on V1; the patch worked as designed."

But hey, the Pixel gets 7 years now! :-)
