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.

I think the actual best footage of the launch was from Everyday Astronaut on youtube, including a great shot of the booster separation

> 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"

[−] procflora 43d ago
This article is plagued by several almost-truths, and gets a lot mixed up.

The thing that is happening for the first time on this mission is humans personally observing much of the far side in daylight. For the Apollo missions the far side was mostly dark because they wanted a high sun angle at the landing site on the near side. Many uncrewed orbiting cameras and even a recent Chinese lander & rover have taken photos of the far side.

It also states that these will be images "from the surface" of the Moon which is wildly off base. Artemis II is not landing... Of course it's true that this O2O technology could be used for high bandwidth livestreams from the surface on future missions, if this test works well.

I don't even think this O2O system will be used for live video during Artemis II. This and several other similar articles all appear to reference a NASA press release that is about the technology in general. The mission-specific NASA reference I found[1] says they will transmit a pre-recorded video "in the lunar vicinity" at 4k using the O2O system, so I would guess this claim of a "livestream" is just misstated.

But Artemis II launched during passover - so a day before the full moon. That means that for a 10 day mission, the flyby will be four days after the full moon. And the flyby is necessarily on the far side of the moon, that's how physics works. So they'll be passing over the far side of the moon four days after a full moon - the far side of the moon will be in almost complete darkness. Not even Earthshine lights the dark side of the moon when it is full.
[−] procflora 43d ago
My understanding is that even that small amount is more than the Apollo crews had. It's all a bit of a marketing line anyway. We can see a good portion of the "far side" from Earth due to the Moon's libration.

Still, it's true that parts of the far side are still unseen by human eyes (if you consider pitch black landscape to be "unseen" which I think is fair given the lack of any significant illumination as you point out).

[−] dotancohen 43d ago
I believe that Apollo 17 spent six days in lunar orbit. I'm not sure at what phase they arrived or left, but worst case they saw the far side three days away from full darkness.
[−] firesteelrain 43d ago
A more accurate claim would be: never-before-seen in real-time at that fidelity from lunar distance.
[−] venusenvy47 43d ago
The article talks about the normal blackout window of 40 minutes on the far side. I'm confused about how they will get real time footage from that side. Is there a lunar relay satellite that wasn't mentioned?
[−] SV_BubbleTime 43d ago
Real time has to be about the most useless factor here. I don’t care if it’s a year delayed, it’s not like I was going to head up there myself.
[−] ErroneousBosh 43d ago
It's not even going to be real time anyway, it's delayed a bit less than a couple of seconds ;-)

You're never going to be able to IPO your space startup with that attitude.

[−] fxtentacle 43d ago
Those were transmitted offline so they didn't have authentic NVENC H264 compression artifacts. Never before have you seen it with 260 Mbps ;)

NASA's rendering of the flyby:

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

[−] albertzeyer 43d ago
Is that real-time or sped up? This video is about 1 minute. How much real time does it correspond to?
[−] cloche 43d ago
Artemis II is expected to be behind the moon for about 30-40 minutes. Around half-way in the video you can see Earth pass behind the moon in about 1-2 seconds. So yes, it's sped up considerably by a factor of around 2000x

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.

[−] PaulKeeble 43d ago
They missed it pulling off the pad, they then had a picture of the plume, the wide shot off the pad was quite a bit too late also, then they missed the separation of the boosters and the upper stage separation.

Honestly it looks like they intentionally missed every high risk procedure intentionally and cut back a few seconds after it had succeeded.You don't make this many mistakes one after the other accidentally, its easier to do this right than wrong, cutting to the crowd as booster separation occurs was clearly intentional. I take this as NASA had very little confidence in this launch and was avoiding showing all the moments it could go wrong live.

[−] dylan604 43d ago
Clearly, you've never worked with a live video crew. If they have no practice, it's amazing how bad you can appear with a lack of appreciation of how fast things move. You also have to remember the camera/operator are really far away with a very large zoom. Things leave your field a view much faster than anticipated. After that, any correction becomes over corrections again because of the zoom factor. Also, I would not be surprised if people were watching IRL as much as their screens/viewfinders.

I've seen it in sports where someone just not up to speed is always behind the play and the center of action is just out of frame. At that point, you zoom out some to recenter and then zoom back in. Or the director cuts away and lets you catch up. But that's assuming competency up the chain.

[−] the_af 43d ago
Agreed. There was high quality alternative streaming from other sources, how come NASA couldn't get their shit together? The spectacle is important for public support!

I still don't understand why they didn't show the final 10 seconds countdown, basically the most iconic moment of any launch. They literally hid the clock! I was hoping to count it down with my family.

If they were scared of accidents they could have streamed it with a delay.

[−] merrychristmas1 43d ago
No, after talking to NASA people, this is just incompetence.
[−] losteric 43d ago
That’s so conspiratorial. They could just stream with a slightly delay to interrupt the feed on disaster. I think it’s way more likely they just didn’t have a good broadcasting team.
[−] z33b 43d ago
The camera and simulation footage were a bit of a letdown and something SpaceX does much better. On the other hand NASA launches do evoke a feeling of substance over form where science takes precedence over presentation. For that money however I concur - I expected more. Especially the simulation footage where the lack of brightness made it hard to see the vehicle - they might as well have used KSP for it
[−] trompetenaccoun 43d ago
Artemis has a budget of over 90 billion dollars, it's more than 4 billion for that Artemis II launch (as estimated by NASA, possibly more because they don't even know exactly how much they're spending). For that price one might reasonably expect a couple of quality cameras for the public to be able to view what their money was spent on. For comparison, a SpaceX ISS resupply mission costs NASA ~$150 million. While that's a very different rocket and mission, that still doesn't account for a 26x higher price!

NASA had their budget cut, but when you look more into it a lot of that never went into spaceflight to begin with.

[−] ck2 43d ago
if you haven't seen the footage from someone in a passenger jet nearby, it rocks

Think about how much technology evolved to create that scene, to fly nearby and being used to take that video, wow

[−] ourmandave 43d ago
They had 4000 people cut in 2025 and big budget cut in 2026.

Maybe that included the camera crews and equipment.

[−] _moof 43d ago
NASA's public affairs office got decimated in budget cuts.
[−] realsharkymark 43d ago
My first thought is SpaceX and Elon would have done this so much better.

I felt I watching the launch through someone's iPhone.

[−] moffkalast 43d ago
Minimum effort has always been NASA's approach to online streaming tbf, 720p potato quality cameras with lots of mission control static shots. I think SpaceX were the first ones to provide anything at full HD with relevant stuff being shown at all times.
[−] piyh 43d ago
Crazy that a dude from Iowa and his ragtag group of rocket watchers does a better job with launch coverage than NASA. I can't believe they cut away during booster separation. Absolute shit show.
[−] whycome 43d ago
It’s not rocket science, it’s media production/direction.
[−] bentt 43d ago
It took SpaceX a number of goes to get their camerawork and streaming right. NASA just hasn’t done this frequently enough.
[−] SergeAx 43d ago
They have all the footage, just not in real time. We are now seeing it being processed and uploaded.
[−] ErroneousBosh 43d ago

> missed pan up at lift-off

Tilt up. Pan is from side-to-side, and the word comes from "panorama".

[−] herodoturtle 43d ago
I’ve read elsewhere that the cut-away during booster separation was intentional given the high risk manoeuvre.

If something went wrong / explosion etc, then they wouldn’t want to broadcast it.

Something to that effect. I’m paraphrasing someone else.

This is amazing. This is a slow burn but live view from Orion https://www.youtube.com/watch?v=6RwfNBtepa4
[−] saltybytes 43d ago
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?

Why does the article keep mentioning footage “from the surface of the moon”?
[−] Cider9986 43d ago

> "will use laser beams to live-stream 4K moon footage at 260 Mbps..."

> "will be used to beam 4K moon footage at up to 260 Mbps."

> "Data rates of 260 Mbps can be achieved..."

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.

[−] yardie 43d ago
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.
[−] ra 43d ago
[−] goodthink 43d ago
With all of the big deal being made about viewing the far side of the moon, you would think they would have performed the mission when the moon is _new_ so the far side would be illuminated...

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

[−] egberts1 43d ago
Still want to know what happened in first 10 second of launch, why were the videos fuzzy and cutting out (at least twice)????
[−] jascenso 43d ago
260 Mbps for 4K seems to be awfully a lot for a single stream. Really makes me wonder what has been used for compression ...
