I was expecting this thread to be more active. Disappointed

I was expecting more video but I’m admittedly clueless about how it works. All I see is a still frame.

Hilarious unintentional quote from NASA to Artemis just a moment ago. They are discussing features they can see now. Speaking of crater names; NASA told the crew they didn't think they would be able to see Schrödinger yet

Is it there, or isn't it ?

Deep space communication has incredibly slow bit rate. The communication channel is mostly comms and telemetry. Video is lower priority.
Internet spoils us with ever increasing speed. But radio still
Has limits

Astronaut Glover quoted Christ before loss of signal. Hope he doesn’t get in trouble for that.
But I loved it. Echos of Apollo 8 and it’s Christmas message.

I heard them say it was a bandwith issue.

Somewhere I read that they are using a new LASER based communication system on this mission rather than radio where possible. Logic suggests the new system could only be used with a line of sight scenario? I would think when they are on the far side of the moon that radio would be the only way. Cool that we are trying out new tech though...thats where break throughs happen.

Yep the new laser is intriguing but it can also only be used at night as the sun causes interference.

When they went behind the moon there was no communication at all as you answered your own question "line of sight".

 

[OrangeTsar]

Most of the communication for Artemis is still traditional radio. If some of the extended telemetry feeds; they give the status of the three main radio antenna banks that comprise NASAs deep space network. Australia, Madrid, and I don’t remember the third one. That means that they always have at least one radio antenna with line of sight to the moon.

They are now on their way home. A five day free fall from a quarter of a million miles ending with slicing into the earths atmosphere at 7 miles per second.
