Hopefully, the footage is better than the missed pan up at lift-off, and showing spectators at the time of booster separation.

I understand funding cuts and all, but this is a once-in-a-generation moment and it’s filmed with no apparent effort whatsoever.

> never-before-seen views of “the far side of the Moon“

I guess not counting all the prior "views" that have been recorded since the Apollo missions, including Chinese orbiters which (according to Wikipedia) "scanned the entire Moon in unprecedented detail, generating a high definition 3D map that would provide a reference for future soft landings"

This in particular warmed my grumpy heart after the best footage of the launch came from a commercial airliners windows.

I had assumed they would've had a better plan to film the entire departure from orbit yesterday.

I'm at least happy they have one for the loop around the moon.

Still want to know what happened in first 10 second of launch, why were the videos fuzzy and cutting out (at least twice)????

Forgive my bluntness asking this question: how hard can it be to put a stationary "satellite" as a communication relay next to the moon to bridge the "dark window" with the space craft?

I wonder what size stream will be available to us. The largest I see in general is 70-90 Mbps for a 4k Bluray Remux and that includes lossless audio. I imagine they would want as much data as possible—significantly more than would be visible to the human eye.

260 mbps is a great headline number, but i'm curious about the protocol and error correction. we struggle with packet loss and retransmits on undersea cables; i can't

Why does the article keep mentioning footage “from the surface of the moon”?

NASA's rendering of the flyby:

Hope we get to see something like this in 4K !

260 Mbps for 4K seems to be awfully a lot for a single stream. Really makes me wonder what has been used for compression ...

How is this possible? I read on HN yesterday that no innovation is taking place and this mission is a waste of money.

Hopefully it’s not cloudy

Didn't Nokia put a 4G cell node up there?

Who is going to be the first to make a smartphone call from the moon?

Lag won't be too bad, just 1.5 seconds or less

the writeup is helpful but i'd want to see how it handles edge cases

How does laser communication work with a moving object with 9DoF?!

A reminder that the illegal DOGE took a chainsaw to NASA personnel last year. If you're disappointed that the feed update wasn't as polished as a SpaceX launch it's because the later has an actual communications and marketing department with a budget.
