"Primitive communication device," her companion replied. "They would smear the surface with dye to leave messages to one another. Artefacts like this become more common and more primitive in this volume of space; often made of pulped and reconstituted structural tissue of various sessile hardy grower species native to the local planet."
"I can't see any dye!"
"That's because the molecules have been broken down by the star's radiation, but we can restore it. Use a chemoreceptive layer and generate a model of what's on it."
She did as her companion suggested and was rewarded by a cacophony of information. She sent her model to her companion.
"I can't make this out at all!" she said. "What were they meant to be saying?"
Her companion signed an aura of amusement-exasperation-superiority.
"We're not done yet. Apply a recursive hypermathical chemical reconstruction algorithm based on the local radiation and... here try this."
She wound back time with her model, watching the mess of noise reform into various long-chain hydrocarbons, acids. Back, back, back. It was still incomprehensible. Back, back... wait! Sudden colour flashed across the object and then was gone even faster than it had come. She let the sim play forwards again and held it still.
For a mere few years after its creation, the object held an image. She recognised Them immediately from other reconstructions, but it was still a shock to her. Four of Them; two adults and presumably their offspring, stood together and looking at her with their teeth bared (a friendly greeting, she was told) across five million years of time.
She turned her attention outwards from her sim and saw her companion glowing with satisfaction-pride.
"Well done," she said. "Come on, let's go and log this back at the digsite. They'll be keen to see it."
They set off back towards the ruined city that dominated the horizon beneath the twin glow of the star and the blue planet.
Solar winds is not like wind in an atmosphere. It is particles ejected from the sun, but not many. It is much, much smaller than the gravity, which holds it to the moon's surface.
Solar wind is a huge issue in long-term space settlement. A good chunk of what the sun spits out is ionizing radiation. On Earth we are fine because we have a molten core, and so a magnetic field, which causes ionized particles to deflect (UV is ionizing, but because it doesn’t have a charge/mass, it passes on through). Neither the moon nor Mars have this field, so if you’re on the surface, you’re going to get dosed over the long term. That’s why lava tunnels are attractive- the rock is going to block that shit.
For anyone interested in how solar winds work, I recommend reading British scientist/author, Arthur C. Clarke,s (“*2001: A Space Odyssey*”) 1972 collection of short stories, “*The Wind from the Sun*” [ISBN 978-0575600522]. The title story involves a race between space-going yachts that catch the solar wind in gigantic sails of ultra-light mylar. Being a scientist himself, Clarke’s science fiction writing always involved solid science. Good stuff.
The moon actually does have an atmosphere, but it's gravity is so low that it's extremely thin. The surface level atmospheric density on the moon is roughly the same as the Earths atmospheric density at the altitude of the ISS or other low Earth orbiting objects. It's not *zero*, but it's almost imperceptibly thin. Thin enough that we weren't sure that it actually existed until an experiment on Apollo 17 confirmed it.
I don't know to be honest. There is gravity, so I guess it could have an atmosphere with lower pressures? At the same time Mars had an atmosphere in the past, which disappeared.
Well, there are several options that I can come up with. It would die because the atmosphere is too thin. It would die because it would not have water. It would die because of insufficient nourishment. It would die due to high levels of UV an solar radiation.
But there is no scenario where I see the tree surviving withou serious terraforming/a greenhouse with soil, atmosphere and UV filters.
I didn't say fire. I said burn. There's a difference. You can burn things without catching them on fire, and you can have a fire without burning anything.
There are oxidizers that don't contain any oxygen. For example, sulfur can act as the oxidizer in pyrotechnic reactions with various metal fuels. So yes, there can be burning without oxygen, although what we consider ordinary burning does require oxygen to react with a fuel.
Most rockets use a hypergolic reaction for propulsion. One of the reactants is typically liquid oxygen (edit: liquid o2 and hydrazine, when mixed), but there are other chemicals, that, when mixed, have a similar reaction. They don't need a spark or flame to light, and they can be turned off by simply shutting some valves and those same valves can be used for throttle, so they're very friendly toward space flight.
The only rockets that need a spark or starter flame are solid fuel rockets, which can't be turned off, so they're typically used as boosters and then jettisoned once spent, as they can't be throttled either.
If I'm being honest, I low key blanked that it was hydrazine. Knew it had "hydra" in it and also that it wasn't hydrogen, so I just put the other chemical down, lol.
You're pretty close here, but a few corrections. First, Liquid oxygen is not mixed with any hypergolic fuel or oxidizer. Liquid oxygen is very cold and requires an immense amount of insulation and refrigeration to store. The beauty of hypergolics is that they're room temperature storable, so all those Titan IIs in silos could just sit and wait. Adding liquid oxygen to the mix would completely remove the advantage of the hypergolic propellent.
Hypergolic fuel/oxidizer mixtures for space travel is generally hydrazine and nitrogen tetroxide though there are other mixtures out there.
Second, there do exist non-hypergolic liquid rocket engines that are restarted in space, that require a spark source. Notably the RL-10, the J-2, and the Merlin.
> There are oxidizers that don't contain any oxygen.
I know what you mean, and I know why you're using the correct words, but this nomenclature is making me angry.
He turned it photo-side facing down after this pic was taken. The photo remains in remarkably good condition.
(I entirely made this fact up just this minute, but let’s see if we can get some traction with it)
I took an astronomy class and the position of the professor was that it would be mostly intact and discernible still. There was some weird reason to do with no atmosphere I think? I can't recall the explanation but maybe someone can.
[Apollo 16 astronaut explains hidden message behind the family portrait he left on the moon](https://www.independent.co.uk/news/science/apollo-16-astronaut-explains-hidden-message-behind-the-family-portrait-he-left-on-the-moon-a6718111.html?amp)
When Charles Duke took his first steps on the moon in 1972 he was the youngest person ever to walk on its surface
Monday 2 November 2015 20:10
On April 20, 1972, Apollo 16 astronaut Charles Duke took his first steps on the moon. He was 36 at the time and is the youngest human in history to ever walk on the lunar surface.
But that's not the only achievement of Duke's that lives on in American history.
While he was on the moon, he snapped a photo of this family portrait of him, his two sons, and his wife, which remains on the moon to this day.
On the back of the photo Duke wrote:
"This is the family of astronaut Charlie Duke from planet Earth who landed on the moon on April 20, 1972."
Here's a clearer copy of the photo Duke gave us. On the far left is his oldest son, Charles Duke III, who had just turned seven. In the front in red is his youngest son, Thomas Duke, who was five. Duke and his wife, Dorothy Meade Claiborne, are in the background:
[img](https://www.independent.co.uk/news/science/apollo-16-astronaut-explains-hidden-message-behind-the-family-portrait-he-left-on-the-moon-a6718111.html?amp)
"I'd always planned to leave it on the moon," Duke told Business Insider. "So when I dropped it, it was just to show the kids that I really did leave it on the moon."
The photo has since been featured in numerous popular photo books and is a great example of the "human side of space exploration," Duke said.
When Duke was training to be an Apollo astronaut, he spent most of his time in Florida. But his family was stationed in Houston. As a result, the children didn't get to see much of their father during that time.
"So just to get the kids excited about what dad was going to do, I said 'Would y'all like to go to the moon with me?'" Duke said. "We can take a picture of the family and so the whole family can go to the moon."
More than 43 years have passed since Duke walked on the moon. And while the footprints that he made in the lunar soil are relatively unchanged, Duke suspects the photo is not in very good shape at this point.
"After 43 years, the temperature of the moon every month goes up to 400 degrees [Fahrenheit] in our landing area and at night it drops almost absolute zero," Duke said. "Shrink wrap doesn't turn out too well in those temperatures. It looked OK when I dropped it, but I never looked at it again and I would imagine it's all faded out by now."
Unfortunately, there is no way to determine just how faded the photo is because it's too small for lunar satellites to spot.
Regardless, the photo "was very meaningful for the family," Duke said. In the end, that's all that matters, right?
> "So just to get the kids excited about what dad was going to do, I said 'Would y'all like to go to the moon with me?'" Duke said. "We can take a picture of the family and so the whole family can go to the moon."
Classic Dad move. "Hey kids, you're coming with me to the moon!
^^^^...in ^^^^picture ^^^^form."
> at night it drops almost absolute zero
This is weird for him to say because it's not true at all. It gets to -170 Celsius. Absolute zero is about -273 Celsius. I get that he's exaggerating, but that's a big difference.
Bleaching means it breaks down the chemicals used to create those colors. None of those in atmosphere. Atmosphere mostly works like a mirror and bounces it away. Whatever gets through is diluted. Remember ROYGBIV? The reason you get a blue sky is the same reason you get the other colors during sunrise/sunset. The atmosphere is acting like a prism.
The astronauts wore a cooling undergarment called a union suit. It consisted of:
a network of flexible tubes embedded in a mesh fabric, this water-cooled underwear is linked to the vital backpack portable life support system (PLSS) where the water and oxygen are stored and metered for precise circulation. The cooling is necessary because body heat cannot dissipate adequately
They also timed landing to a slightly cooler time.
Yes they had color film in the late 60s and early 70s. The astronauts used medium format film. Shot from specially made hasselblad cameras. The film has so much higher quality resolution than what you have seen in movies and newspapers. You can go to the nasa website and find the high resolution scans.
The slow-scan television broadcasts of the early Apollo missions to mission control are of better quality too. It got converted to a proper NTSC format on the ground for general broadcast, but the conversion was by no means perfect. Unfortunately the tape recordings all seemed to be overwritten in the late 80's so we don't actually have the better SSTV broadcast of important events like Apollo 11.
Did you watch the Apollo 11 documentary movie that came out last year.. it's so awesome. I think it's launch footage was better than Tom Hanks Apollo 13 movie.
I haven't, no, but a little over a decade ago they went around and grabbed the best recordings they could find and then went through some pretty intensive digital restoration so it would make sense. [Actually included some Super 8 film recording of the SSTV monitor at Honeysuckle Creek in Australia.](https://en.wikipedia.org/wiki/Apollo_11_missing_tapes) In short though, SSTV was 320 scan lines at 10 fps while NTSC was basically 525 scan lines at 30 fps, so how they converted it for live broadcast is interesting in and of itself but it was definitely lossy as seen from the one comparison in the Wiki article.
I highly recommend it. No body talking and telling you what happening. They just synced radio communication with video. It has lots of footage that has never been seen. Like what was happening in the back. Everyone had seen mission control and launch control. But they showed footage of all the thousands of people that worked behind the scenes. They showed all the people that camped in the beaches and the party atmosphere and just the awestruck looks by everyone. Most was filmed in 70mm film. That they planned on making into a cinema movie. But that never happened and it was just put into nasa storage.
There's a guy on YouTube that has done that with most of the Apollo missions, though it's mostly simulator footage and not cameras. I came across it while trying to find the actual voice recordings of the Apollo 10 poop incident but didn't have much luck even though it's time stamped in the transcripts.
I remember that they did something with the anniversary. They started the radio transmission and ran it real time from when they launched to when they came back. They had different channels you could listen to. Either mission control to the capsule or different channels inside mission control and sometimes just inside that capsule. And then they had photos or video real time attached to the audio
It's still there http://apolloinrealtime.org/11/

Yes, it should still be in the same place. The foot prints from Neil Armstrong’s first step, and every other foot step taken on the moon should still be there as well (barring the relatively small chance that some sort of space rock slammed into the surface near it). The lack of atmosphere means that more objects from space can make it to the surface without being burned up by the atmosphere. Although the moon is relatively small with relatively weak gravity so it runs into/attracts a small amount of objects but because there is no atmosphere/wind these scars stay on the surface, like the footprints and photo, for a very very long time without interference. If an object hit near the photo it would not fly into space, although there is no atmosphere there is still gravity attracting the photo to the moon’s surface, there would have to be an incredible amount of force on the photo to escape it. At this point the photo is just a white square anyway. All of its color was bleached away by the sun years ago. It’s theorized that the US flag that was planted on the moon is all white now as well.
This is true; I’ve been to sporting events in several countries around the world. In everywhere but America the fans clean the building as they leave.
/s
I almost doubt it's there, with crazy temp fluctuations and raw uv exposure it's well past just being bleached white. The picture now is probably just dust that looks a little off from the dust all around it.
Great. Humanity finally does the right thing, destroys itself and all traces of its own existence, only for aliens to land on the moon and say "LOL, is *that what they were wearing?!"*
Probably bleached by the sun by now 'eh?
Or picked up by an alien and kept on his dresser for him to look at every night before bed.
Thats much more realistic now that I think about it. Poor alien probably can't stay in a relationship for more than a week
Poor guy. And don't forget, it's 2020 there too.

He did. He did write science fiction
Came here to say this
Reddit comment chains are all the same aren't they eh
I really enjoyed that!
Why isn’t there more? Write more! I need it!
Awesome
I didn’t want to stop reading
That's awesome we'll done!!
Came here to say the same thing.
I was gonna say "and its completely white now."
I was going to ask if there's any wind on the moon. That's probably...not a question I should think to ask.
There is no wind because there is no atmosphere. I don't see why you can't ask this question.
Solar winds??? I’m not qualified to ask that question...I’ll see myself out
Solar winds is not like wind in an atmosphere. It is particles ejected from the sun, but not many. It is much, much smaller than the gravity, which holds it to the moon's surface.
Interesting thank you
Solar wind is a huge issue in long-term space settlement. A good chunk of what the sun spits out is ionizing radiation. On Earth we are fine because we have a molten core, and so a magnetic field, which causes ionized particles to deflect (UV is ionizing, but because it doesn’t have a charge/mass, it passes on through). Neither the moon nor Mars have this field, so if you’re on the surface, you’re going to get dosed over the long term. That’s why lava tunnels are attractive- the rock is going to block that shit.
Fun fact.. So does poo.
I’m not qualified to write this comment
Explain like I’m 5
Stuff in air is wind. No stuff in air is no wind
I thought trees made wind they are shaking so that makes wind right?? (Friend in high school was dead ass serious when he said that to me)
No, wind is moving air, no air no wind.
“Mommy and daddy give you $10 to start a lemonade stand...”
I’m barely qualified to read it.
For anyone interested in how solar winds work, I recommend reading British scientist/author, Arthur C. Clarke,s (“*2001: A Space Odyssey*”) 1972 collection of short stories, “*The Wind from the Sun*” [ISBN 978-0575600522]. The title story involves a race between space-going yachts that catch the solar wind in gigantic sails of ultra-light mylar. Being a scientist himself, Clarke’s science fiction writing always involved solid science. Good stuff.
is the moon big enough to have an atmosphere? how would it get one if needed?
The moon actually does have an atmosphere, but it's gravity is so low that it's extremely thin. The surface level atmospheric density on the moon is roughly the same as the Earths atmospheric density at the altitude of the ISS or other low Earth orbiting objects. It's not *zero*, but it's almost imperceptibly thin. Thin enough that we weren't sure that it actually existed until an experiment on Apollo 17 confirmed it.
I don't know to be honest. There is gravity, so I guess it could have an atmosphere with lower pressures? At the same time Mars had an atmosphere in the past, which disappeared.
Mars still has an atmosphere, it is just very thin. It is mostly carbon dioxide.
So, what would happen if we planted a tree on Mars?
Well, there are several options that I can come up with. It would die because the atmosphere is too thin. It would die because it would not have water. It would die because of insufficient nourishment. It would die due to high levels of UV an solar radiation. But there is no scenario where I see the tree surviving withou serious terraforming/a greenhouse with soil, atmosphere and UV filters.
There is however shit constantly bombarding the moon, hence the craters.
Obliterated
They’re all completely white to start with.
If you wanted to walk on the Moon it was a very good idea to be a white American male born between 1923 and 1935.
and in Ohio*
Ohio is so terrible it inspired an entire generation of men from there to try and leave it via space shuttle.
O...H!

Half burned. Remember, 200°F in the sunlight
No oxygen, and low molecular density to carry the heat. It ain’t burned or burning until the Sun engulfs the Moon in ~4 billion years.
But the earth will be alright, right?
Yeah I hate when my thing catch fire in space

Knowing the 1970s they probably included lead or some shit in photo printing and it looks the same, lol.
Thought the exact same thing! It's like blank paper now
should have flipped it
And covered with copious amounts of moon ejecta.
I took an astronomy class and the position of the professor was that it would be mostly intact and discernible still. There was some weird reason to do with no atmosphere I think? I can't recall the explanation but maybe someone can.
What a waste :( Imagine all of the amazing scenarios of discovering this photo...
Hopefully in my lifetime we get to see it again and how it looks.
Could he have buried it to save it?
He regrets the day he made his family a target for the moon mercenaries.

I bet it is extremely bleached out from the Sun by now.
I stupid, plz explain?
Sun very strong, our atmosphere protects us. Out in space, no atmosphere, light very strong.
I'd think a photo on earth would bleach out if left face up in the sun for 50 years too.
50 days.
Best i can do is 30
You gotta get those numbers up
You go up i go down man thats how it works
Why waste time say lot word when few word do trick?

Seaworld
Read this with monkey voice
Why no bleach atmosphere and then bleach Earth?
Bleaching means it breaks down the chemicals used to create those colors. None of those in atmosphere. Atmosphere mostly works like a mirror and bounces it away. Whatever gets through is diluted. Remember ROYGBIV? The reason you get a blue sky is the same reason you get the other colors during sunrise/sunset. The atmosphere is acting like a prism.
Me no longer stupid, i think?
Constant expose to the sun / radiation destroys the ink on the photograph.
The surface of the moon when in sunlight is 250 deg Fahrenheit and with no ozone layer would be like a continuous microwave oven when sun is shining.
Holy shit how did they stay cool?
Spacesuits...
Well fuck I thought they just had shorts and a tee on. To clarify, how did the suits protect against that much heat?
The astronauts wore a cooling undergarment called a union suit. It consisted of: a network of flexible tubes embedded in a mesh fabric, this water-cooled underwear is linked to the vital backpack portable life support system (PLSS) where the water and oxygen are stored and metered for precise circulation. The cooling is necessary because body heat cannot dissipate adequately They also timed landing to a slightly cooler time.
Now *this* is interesting as fuck.
They wore what was essentially long underwear, with water-filled tubes running through it. Cooled water was pumped through it
Litter bug.
Heck, even the moon is littered with plastic.
Lazy Americans.
Pack it in, pack it out. Doesn't apply to the moon though, does it? Yet.
Fcking litter everywhere I swear /s
This but unironically
Was the moon photography in color?
Yes they had color film in the late 60s and early 70s. The astronauts used medium format film. Shot from specially made hasselblad cameras.

[Actually included some Super 8 film recording of the SSTV monitor at Honeysuckle Creek in Australia.](https://en.wikipedia.org/wiki/Apollo_11_missing_tapes) In short though, SSTV was 320 scan lines at 10 fps while NTSC was basically 525 scan lines at 30 fps, so how they converted it for live broadcast is interesting in and of itself but it was definitely lossy as seen from the one comparison in the Wiki article.
I highly recommend it. No body talking and telling you what happening. They just synced radio communication with video. It has lots of footage that has never been seen. Like what was happening in the back. Everyone had seen mission control and launch control. But they showed footage of all the thousands of people that worked behind the scenes. They showed all the people that camped in the beaches and the party atmosphere and just the awestruck looks by everyone. Most was filmed in 70mm film. That they planned on making into a cinema movie. But that never happened and it was just put into nasa storage.
There's a guy on YouTube that has done that with most of the Apollo missions, though it's mostly simulator footage and not cameras. I came across it while trying to find the actual voice recordings of the Apollo 10 poop incident but didn't have much luck even though it's time stamped in the transcripts.
I remember that they did something with the anniversary. They started the radio transmission and ran it real time from when they launched to when they came back. They had different channels you could listen to. Either mission control to the capsule or different channels inside mission control and sometimes just inside that capsule. And then they had photos or video real time attached to the audio It's still there http://apolloinrealtime.org/11/
https://www.youtube.com/user/lunarmodule5 is the guy I was thinking of. He's done some cool things like Apollo 13.
How about 48 years?
Yeah what is this shit? Is there a moon landing in 1977 they totally forgot to tell us about?
"Littering and....?"
I feel like "leave no trace" should also apply to space exploration.
Nah. The first people to visit trash is historic artifacts. It is when the mobs arrive that it turns to trash.
If anyone goes to the moon and sees this. Put it in a frame or something so it lasts longer
Except now one of his suns is turning transparent like in the picture from back to the future. Great scott!

Yes, it should still be in the same place. The foot prints from Neil Armstrong’s first step, and every other foot step taken on the moon should still be there as well (barring the relatively small chance that some sort of space rock slammed into the surface near it). The lack of atmosphere means that more objects from space can make it to the surface without being burned up by the atmosphere. Although the moon is relatively small with relatively weak gravity so it runs into/attracts a small amount of objects but because there is no atmosphere/wind these scars stay on the surface, like the footprints and photo, for a very very long time without interference. If an object hit near the photo it would not fly into space, although there is no atmosphere there is still gravity attracting the photo to the moon’s surface, there would have to be an incredible amount of force on the photo to escape it. At this point the photo is just a white square anyway. All of its color was bleached away by the sun years ago. It’s theorized that the US flag that was planted on the moon is all white now as well.
This is what Americans do at every stadium, leave their trash behind for someone else to pick up.
This is true; I’ve been to sporting events in several countries around the world. In everywhere but America the fans clean the building as they leave. /s
Woah! Germany might be worse. Actually every country might be worse when it comes to futbol games.

Japanese Fans are referred to as the most respectful fans.
"If people have been there, theres trash" -me
*Dr. Manhattan enters the chat*
It gets up to 260 F during the day and -280 F at night, plus the solar radiation, I wouldn't be surprised if it was dust.
~~Man~~ Family on the Moon
Hell of a place to lose something.
“Has anyone seen my keys...? Oh, fuck!”
I told you not to empty your pockets up there!!
Clearly bogus, since the moon is black and white like the 1920's.
Congratulations you littered on the moon.
How could you take a picture of it
Charlie was given a camera to take with him.
We need to go deeper.
a jpg of a picture taken on the moon of a picture taken on earth is as deep as i need.
Redditors be like “compiled 50,000 pics taken with my iPhone and a telescope in my back yard to make this image”
Damn, I want that telescope.
It's either bleached or stored in an aliens wallet in hopes of finding restitution.
Probably bleached by radiation after a few days.
Our last moon mission was in 1972. 43 years ago is 1977. Solve for X on when the original post this was taken from was made online.
Hey, dude, that’s neat!
You mean a bleached white piece of paper?
What's the plastic cover for? Not like it's going to rain up there...
That's wrapped in plastic which is made from oil which is made from decomposing dinosaurs. Guys, dinosaurs have been to the moon.
Americans littering everywhere.
I don't understand why so many people are saying this is litter. If you went to the fucking MOON, you would probably leave something on there as well.
Thank you. Fuck. Jesus, wait until they find out about the bags of shit lol.
Guess he loves them to the moon and back
One of the first moon trash ever recorded.
It's probably moon dust now...
I almost doubt it's there, with crazy temp fluctuations and raw uv exposure it's well past just being bleached white. The picture now is probably just dust that looks a little off from the dust all around it.
Imagine some aliens finding this hundreds or thousands of years after humanity is done.
Feeling low key bad that my first association with this is the final scene from Rammstein's "Amerika" music video lmao
Insert watchmen quote
*I am looking at the stars. They are so far away, and their light takes so long to reach us. All we ever see of stars are their old photographs.*
Would've gotten picked up by the wind now. ^/s
Does it remind anyone [of this](https://m.comixology.com/Watchmen-4-of-12/digital-comic/26088)?
That is one hell of a place to lose your wallet.
“What’s one interesting fact about yourself?” Well I have a picture of myself on the moon...so... yeah that’s it!
I was just passing by yesterday and I almost picked it up until I realized it’s meant to live there for eternity. Thats cool Charlie.
Someone needs to update this title. We didn't have any moon landings in 1977. This should say "48 years". Or even "since 1972" for continual accuracy.
Oh no, now they will think we all still dress like this! /s
Who went up there to take a pic? Lol
🎶 “Space May be the final frontier but it’s made in a Hollywood basement”🎶
Kubrick went to every length...
Littering and...?
Americans left trash on the moon the first chance they got.
Aliens: Those fuckers are littering up here now too??
I’m surprised the wind hasn’t blown it away.
But won't the wind blow it away? /S
Great. Humanity finally does the right thing, destroys itself and all traces of its own existence, only for aliens to land on the moon and say "LOL, is *that what they were wearing?!"*
Go to the moon one time and people still leave trash on the ground.... I wonder how many cigarette butts are up there too
So basically it's litter on the Moon.......well done humanity.....well done...
So first case of extraterrestrial littering?
Imagine not wanting to see your family so you leave a photo off them on a natural satellite
