It's fascinating how the pictures have that "Apollo moon landing" look. I'd always assumed that a huge part of this was just 1960s technology (film not digital etc), but apparently it's actually coming from the literally unearthly lighting conditions of being on the Moon.
codelion
that's a great point about the lighting... it really does contribute to that distinctive look. i've also read that the lack of atmosphere on the moon sharpens the shadows and increases the contrast, which probably adds to that effect.
stevage
Yeah it's the lack of atmospheric scattering.
porphyra
Yeah due to the lack of a blue sky, shadows on the moon are basically completely black and challenging to photograph.
Also the Hasselblad camera they sent to the moon back then was actually pretty good even by modern standards.

> 1960s technology
Still photography has gotten more convenient since then, but in the agreeable lighting and atmospheric conditions one would encounter while taking a vacation snap outside at noon Cynthian time, image quality now isn't better than then*

OP is comparing photography tech that made it to the Moon, so not cheap tech. The "special" way the photos look like is probably more a product of the environment than just the equipment.
gonzo41
Well it's either that or the tin foil hat people will say they just rented the OG soundstage.
Nvidia did a great presentation about the lighting for the original. https://www.youtube.com/watch?v=syVP6zDZN7I

Once SpaceX gets Starship launching weekly, it'll probably be cheaper to send a bot with a camera to the moon than to rent a sound stage and build a big set!

I am no expert, but to my knowledge the space flight tech evolves very slowly, if at all. One reason for that is that modern tech is supposedly too sensitive to radiation. So you want to balance what's worthwhile to upgrade, and fancy videos are probably low on that list.

Space engineer here, not exactly true, esp for non-critical systems. Check out the "Careful COTS" paper by Doug Sinclair

The Apollo astronauts used Hasselblads for still photography. I'm pretty sure Firefly is not sending back rolls of 6x6 film.

These pictures are great - maybe it's time for me to get a new desktop background.
Kinda related: some years ago NASA published all the Apollo missions pictures. I downloaded all of them (hundreds, maybe bit more), acting as a photo editor then I selected "good ones", cropped them to 16:10 format and made a background picture pack - I'm using it on all my devices since then. If someone is interested, they're published at [0] - feel free to use.

Pity that the videos were accompanied by such cheesy music. A soundtrack derived from telemetry would have been killer. Example project here: https://www.youtube.com/playlist?list=PLbLdd1fdNg5ymNYshv2xW...

Flickr? Moon landing? What year is it?
sen
Flickr has had a resurgence of popularity among photographers since yahoo sold it. It’s easily the best “professional” photo hosting site currently.
consumer451
This is an interesting tangent. Is it Flickr's copyright rules that make it attractive? Or, something else? Lack of existing competitors? Not associated with a social media account?
chefandy
If you’re going to post albums of high-res photographs on the internet… why not Flickr?
duxup
The videos are amazing

Absolute cinema, Firefly showing how it's done.
zingerlio
How are the videos captured or processed? The solar lens flares are smoothly interpolated but the moon surface shows lower FPS, almost feels like the flares were on a separate layer.
dguest
My guess: they are the same update rate. The lens flares have blurrier edges and move less across the screen. This makes the jumps less obvious.
CGI animations also add blurring, and even your eyes have an integration time that will make fast moving objects blurry. So your brain good at interpolating blurry edges.

Horray!
Also:
- Wow but the moon is 3D. Like, when we see shots of Earth, the ground always looks so flat, but the depth of the craters and the heights of the ridges is really, really amazing to see
- ...KSP did a really good job mimicking the real thing
nerdponx
I noticed this too. Something about the perspective is unnerving, like an amusement park ride. You can see clearly that the moon is small, the craters are big, and the orbiting spacecraft is moving really really fast, all at the same time. None of that is apparent from video of low Earth orbit. And then the stark lighting makes it feel even more bizarre and alien.
consumer451
The most 3-D experience that I have had with the moon, on the cheap, is when its not in it's full phase. With a cheap telescope, when you observe the edge of the partial-phase moon's crescent, you see the "terminator." It suddenly feels so different, finally you see the moon's bumpy spherical nature. It's like you are flying just above it.
> The terminator is where you'll see the most pronounced shadows cast by the lunar features like craters, mountains, and valleys. This is because the Sun is at a low angle relative to the lunar surface, emphasizing the topography and allowing you to see craters and other features in sharp relief

> - ...KSP did a really good job mimicking the real thing
The pic with the shadow of the lander is really close to what you get out of KSP when you first land on Mun or Minmus. Really really cool. Congrats to everyone who made this happen!
moffkalast
Interesting how Luna has more of a Minmus feel in terms of scale, the horizon is so close. Something to do with the wide angle lens I imagine?
cryptoz
One of the coolest things ever is you can see the shadows and depths of the craters on the moon from here on Earth, with a cheap ~$15 telescope or probably binoculars too. I remember buying the galileoscope for $15 many years ago and was absolutely shocked how cool the moon looked, and how 3D.
Pro-tip: the full moon isn't so fun to look at, you want some level of crescent moon so you can avoid getting overloaded on the brightness.
(You can also stay up for a few hours and actually observe Io revolving around Jupiter, I think it takes most of the night to get 1/4 of the way around. Pretty obvious revolutions when you keep observing throughout the night.)

Congrats to everyone involved!
I planned to watch the live stream but wasn't able to. The moment of successful landing was quite modest, only a mostly-static screen with telemetrics was shown to the public, but it absolutely felt magical. It feels like the moon is well within humankind's reach by now.
Coincidentally, I found a copy of Uchu Kyodai (by Chuya Koyama) in my local library, and started reading it recently. It's fun to compare the perspectives from more than a decade ago, to the actual development we have right now, regarding space exploration.
(This was posted to another thread, but I moved it here after I realized comments were moved)

> It feels like the moon is well within humankind's reach by now.
It has been for the last 65 years. ;)
BurningFrog
It's now within reach for a medium sized corporation, largely ignored by humankind.
That's huge progress!
kibwen
It's not any more or less out of reach for a medium-sized corporation than it's been since the 70s. The reason no corporation has gone is that there's no economic incentives to. And there's still not; this is a NASA mission, it's exploratory science funded by the public.
agentkilo
Yeah that's true, but I haven't really experienced the Apollo era personally. After the "gap" between the old space race, and the new race inspired by private space agencies, I do feel we are getting closer, to the moon at least.
somenameforme
Something most people don't appreciate is that, outside of the distance, Mars is super easy mode compared to the Moon. The Moon has 2 week long nights cycling between highs and lows in the range of -130C to +120C, inhospitable terrain, constantly getting pounded by meteorites, no atmosphere whatsoever, much higher radiation, much less gravity, and so on. Mars, by contrast, is oddly similar to Earth - similar day/night cycle, even a similar axial tilt meaning similar seasonal cycles, relatively reasonable temperature ranges, some atmosphere, and more.
This is why the image of the Moon as a stepping stone to Mars doesn't really make any sense. The Moon is very much 'hard mode', but it's closer. So the main tech issue to make up (long distance travel) is not one that progress on the Moon will go much towards advancing.
BlueGh0st
What a strange name.
tombert
Hell yeah!
It would be very cool if we are able to properly colonize the moon in my lifetime. Even if we don't have humans living there like in Futurama (as cool as that would be), it would be unbelievably cool if we have constant back-and-forth trips to the moon.
Or we could just blow it up, which might be fun in its own right: https://youtu.be/GTJ3LIA5LmA
consumer451
As far as flights of fancy regarding the moon, I enjoyed Randall Munroe's "What if we put a pool on the moon" thought experiment. I would enjoy the experience of propelling myself out of the water like a dolphin!
owenversteeg
Fun fact, both the US and the Soviet Union had plans to nuke the moon in the 50s. US Project A119 and Soviet Project E-4.
SoftTalker
There is no reason for humans to ever return to the moon. The cost and risks are not justified. Drones and robots can do anything that needs to be done. They don’t need to breathe, they don’t need to sleep, or eat.
tombert
I think it would be cool, and I don't know that I care if there's a "reason" to do it other than "human achievement".
I mean, there wasn't really a "reason" to go to the moon in the 60's either. I think I more or less agree with JFK on this:
"Many years ago the great British explorer George Mallory, who was to die on Mount Everest, was asked why did he want to climb it. He said, 'Because it is there'. Well, space is there, and we’re going to climb it"
I could try and find a lot of justifications about medical research or something, and those might be cool, but it would be dishonest if I pitched those as a "reason" to go, because I would want us to return even if those reasons weren't there.
xoxxala
If you haven’t heard it, Public Service Broadcasting used the JFK speech in their song “The Race for Space” from the album of the same name. If you’re even partially a space nerd, it’s worth a listen. Very inspirational and the final album track is relevant to todays news.
bruce511
When Mallory climbed on Everest (and possibly summited) it was a big deal because it had never been done. When Hilary and Tenzing did it, it pushed human achievement forward.
Today people still do it, but it means nothing to anyone other than those people.
Going to the moon in the 60s was an impressive feat. It pushed the boundary forward. But that's all it did. There's literally nothing of value there.
Sure most of the people who saw that are dead, or will be in the next 20 years. So it will seem "cool" to the next generation. But selling "cool" to a congressional appropriations committee is a tough sell.
We aren't gonna colonize the moon (or indeed mars) because frankly it would be too expensive, and there's no point. There literally is nothing to gain from a colony in either place, and there's no way to fund it (and no reason to fund it.)
Aachen
Tell that to the people of deadliest catch and dirty jobs: we have robots now that can do everything we want to without needing to sleep or eat! Sadly, we're not using them because they don't exist yet...
alistairSH
They probably could exist, they’d simply be more expensive than putting a human on a boat.
The relative costs are flipped for putting a human on Mars/moon - the robot is cheaper.
gorgoiler
Not that anyone’s offering me the choice of course but I’m happy to leave it to the robots. Lunar dust gives me the creeps.
Imagine stepping outside into a world where absolutely everything is coated in dark gray copy toner that gets ingrained into all that touches it.
I don’t think I could do it due to the anxiety.
tombert
I'm too tall and I don't have twenty PhDs so I don't think "astronaut" is really on the table for me, but I would absolutely go to the moon if I had the opportunity.
The dust would give me some anxiety too but I think it would be worth it.
Salgat
Robotics is unfortunately not there yet, unless we plan to send everything there fully assembled with zero maintenance ever. Unless you mean purely for basic exploration.
ocdtrekkie
But if we are to go more interesting places... shouldn't we have down breathing, eating, and sleeping on the moon so well that it isn't much of a cost or a risk? It's inherently a good testing ground for things we need to do reliably much further later.
Imagine if we never built ISS because putting a space station in Earth's orbit was a solved problem...
robbomacrae
I'd like to see us colonize Antártica with a self sufficient colony first. Seems like a much cheaper testbed.

"I've been saying we should do this for years. I walked on the moon. Did a pushup, ate an egg on it. What else can you do with it?"
Mr Show has held up well, maybe even gotten better with time.

There's that pale blue dot! Nice selfie.

For those who don’t live in Texas, many people who live in Cedar Park would say they are from Austin. It’s a suburb to the North. I know an engineer from Firefly from years ago. She was always fascinating to talk to. I also sold my MK3s+ 3D printer to a firefly employee via Craigslist a few years ago.
I’m glad they’re having some success.
buerkle
And they do all their manufacturing in Briggs, TX about 30 minutes north of their HQ.

Super cool! Good working with you guys ;-)

Super cool. This is one of those things you watch and just "feels like the future". I know, we've been there before but it still feels like an awesome event.
(someone go back to Venus, I know it's hard, but someone please)
Here are the pictures it has taken so far:

There's also a cool lunar flyover video taken during final deorbit.
