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, it…

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 s…

Isn't Trump supposed to be the king of spectacle? Why weren't there fighter jets doing low-passes supersonic for each final second?

Alright, Kif, let's show these freaks what a bloated, runaway military budget can do

> evoke a feeling of substance over form... The feeling it evoked in me was that a multi billion dollar PR program could surely afford to spend a little bit of money on reliable camera tracking, telemetry overlays, visualisations that run at more than 0.1 FPS, etc. Absolutely bizarre.

Indeed. This has been my gripe since first SpaceX booster landing attempts - I understand that "livestream from an IMAX camera" may be very low at the list of priorities for space missions, but... it shouldn't. Even if recovered after the fact, having a solid, high-quality footage from flight and orbit would make a huge impact on the publicity goals they're all explicitly trying to achieve. There's a shortage of good…

no? why you think it would ? We know how it looks like already

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.

My first thought is SpaceX and Elon would have done this so much better. I felt I watching the launch through someone's iPhone.

SpaceX did it worse for a while, took them some launches to be better

NASA's public affairs office got decimated in budget cuts.

They had 4000 people cut in 2025 and big budget cut in 2026. Maybe that included the camera crews and equipment.

Why isn't NASA hiring a normal production company?

With what money? The budget for it got cut.

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.

Don't they usually manage that by having the broadcast be slightly delayed?

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?

We have DSN already. As for the moon, it is a nightmare to orbit. Its density is very lumpy, which means orbits around it are constantly being perturbed, and that means you need to bring an annoying amount of propellant if you want to remain stable.

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

Almost for sure would be multiple camera feeds. But also wouldn’t be unreasonable to have a bitrate that high. I had a Sony camera that did 100mbps and that was just a prosumer camera.

For the raw footage of something with as much contrast as the moon against a backdrop of space it would make sense to use a format like ProRes that preserves more dynamic range.
