What will the live video and audio quality be like when we watch an Artemis crewmember set foot on the moon?
The quality of the original Apollo footage from the 1960's is terrible by today's standards. I don't know if the reason for it has something to do with some limiting technology or physics about being at the moon, but I assume we now have the technology to send a digital stream from the moon at reasonably high bandwidth, but I don't know how much bandwidth will actually be allocated to it or what technology will be used.
Also, I assume we are still limited by the speed of light to some minimal amount of latency, but will the back-and forth conversation latency be substantially more than what is necessarily incurred from the limitations of the speed of light - perhaps due to relaying information through a multitude of satellites and broadcasting infrastructure? It's been a long time since we've chatted with anyone 384,000 km away.
I'm hoping it will be at least as good as someone live streaming on a modern smartphone. What are the reasons it might not be? Lots of live spacewalk footage from the ISS has great video, but the audio is still very band-limited. I don't know if that's a bandwidth issue or something to do with near-field microphones in spacesuits that attempt to accentuate the voice and reduce extraneous noise (like most air traffic communication) or just old tech that we haven't upgraded yet.
So, are we going to get an ultra-high-def live stream or it is going to be terrible?
Representative audio and video quality from the Apollo 11 EVA can be seen in this video. Hopefully it will be better than this!
