Why NASA used Paint By Numbers to Make Their First Mars Picture

[@-jeff-]

I'm old enough to remember those missions and the great disappointment that Venus was a furnace and Mars was a desert.

[@dewiz9596]

[@leslienordman8718]

Yes, very true!

[@serronserron1320]

And honestly fringe science has made its way into many officials agendas who are hell-bent on proving those two planets were originally much like earth and its conditions when in fact there's no solid evidence that Venus or Mars were ever earth like.

[@thetooginator153]

Jeff - I’m just a little bit younger than you, but I was really excited to see the images from the surface of Mars in 1976. Now we might as well have people on Mars because we have fantastic images of the surface. I hope we both see some actual high-res video too one day. Oh, and let’s not forget that we got to see some nice images of Pluto!

[@rstainsbury]

I get what you mean. Like, there COULD have been tropical rainforests beneath Venus’s clouds…until the photos prove otherwise. I’m similarly disappointed that all the exoplanets we’ve found so far are lifeless.

[@frankhage1734]

In the '80's, before scanners were common and computers were expensive, my boss taught me to record the values on a "strip chart", then cut out the peaks of interest and weigh the paper to calculate the area under the peaks. This also works trying to compute the area of something with a complex boundary. It was literally cut and weigh.

[@hubbsllc]

Analog integration! I love it! The Quantitative Physical Science class I took as a high school freshman was one of the most important formal classes of my entire education. One of the exercises was to estimate the area of Tennessee two ways from a printed map of the state: using a planimeter (Google that; it's analog-mechanical and it's amazing) and cutting out the map carefully from a pair of scissors and weighing it with a balance (a pre-measured square inch on the same piece of paper was used as a reference). Both methods came very close.

[@bensmith3304]

This is also how biologists calculated the volume of cells. They would make serial sections, image the sections on a transmission electron microscope, and then cut out the parts of each image that belonged to a single cell, and weighing the film. Stacking the cutouts also gave you a pseudo-3D reconstruction of the cell, although the Z-axis aspect ration would be off.

[@donnamccann1382]

Yep, this was standard technique for finding peak area from any spectrometer that output to an analog pen plotter. The first "integrators" I saw when I was doing research in college seemed almost magic. They weren't very sophisticated, as they simply plotted a sawtooth line where the velocity of the pen moving up and down varied in proportion to the peak height it was interpreting. Instead of weighing the aluminum foil cutouts, you would count the number of times the sawtooth pattern went up and down.

[@tomahzo]

Analog low-tech! Love it! :D

[@worldcomicsreview354]

@@bensmith3304 I used to work in a building in Cambridge University that had been established in 1950, and still had some odd old equipment and bits kicking about (apparently they'd not long chucked out an old microscope with attached bellows camera not long before I started). In one room was a complete electron microgram of a rat's brain, made up of probably 50 photos cut up and assembled like a jigsaw.

If you take their "painting", convert it into the correct aspect ratio, and make it B/W, it's impressively close to the official photo, considering that they were only using 5 shades instead of 64. The main features can definitely be found in the full-depth photo.

[@Acecool]

Scott always finds these interesting little historical nuggets. I'd like to see a blink comparison between Mariner 4 images and the same area shot by Hirise or some other high resolution camera, just to get an idea of what those early pictures really show.

[@dudermcdudeface3674]

The magic of being one of the first humans to see something is incredible. Today, even just being the kind of nerd who constantly refreshes a NASA page to see them put up a new image, I know that I've been among the first few thousand humans to see at least a few things.

[@nakfan]

I remember doing exactly that when they downloaded the first

[@Touay.]

The really fascinating story for that is that the russians, not having the means to receive a radio transmission from the moon of the first image, had it sent to the jodrell bank radio observatory in the UK, so they could receive the image and print it ... the first image sent from the moon.

[@RRaquello]

I don't know how it was in the early days, but I was a kid during Apollo, and you could send to NASA and ask for all kinds of things, like pictures, and they'd send them to you. When one of the moon missions were coming up, I'd write a letter to NASA and say something like "I am a school child and we in our class are studying the upcoming trip to the moon on Apollo 14 can you send me some information and pickters so I can learn all about it" and a couple of weeks later you'd get a big envelope with pictures, maps, newsletters and even the detailed schedule of the flight like they gave to reporters. Practically whole press kit. About the only thing they didn't send was a mission patch, which is what I was always hoping for. I even remember them sending follow-up packages after the flights and after Apollo 13 they sent me an updated full color 8 x 10 photo of the Apollo 13 crew with Jack Swigert instead of Ken Mattingly, and I still have that picture. Most of the other stuff I've lost, unfortunately. It's too late now, but maybe if you had sent to JPL at that time they might have sent the pictures for free. NASA had a big PR budget and were just giving stuff away to the public if you asked for it.

[@patreekotime4578]

What a fun junior high or HS project it would be to produce images this way.

[@ninehundreddollarluxuryyac5958]

I am so old that I remember these things happening. I'm not sure if we saw the Ranger spacecraft crash into the moon in real time, but I do remember seeing them on television. Those showed what you'd expect, craters and smaller craters getting closer and closer until the screen goes blank or I think it was filled with what we used to call "snow" which was random noise picked up by analog television receivers. Digital screens blank this out, but if you tuned an analog television to a channel where no one was broadcasting, you saw this moving grainy pattern we called snow. Yes, it was possible to tune to an unused channel even when your set only had 12 channels. Usually there were only three active channels in the city, maybe one in the countryside. Getting back to Mariner and the first Mars flyby. Nobody had any idea what Mars was like. I mean NO FRIGGIN CLUE. The best telescopes made fuzzy images and ordinary people were not allowed to look through them. Our best official dudes looked through the telescopes we had all pooled our money to buy. Every one of those dudes told us a different story about what they saw through our telescopes. Some even saw cities with alien civilizations. Others said those cities had long fallen into ruin. Still others saw jungles of red trees. I kid you not! This was our world the day before the flyby. I was very young at the time. As an emerging nerd, I had a fascination with dinosaurs, partly because they had this narrative with gigantic animals and science. The animals no longer existed, but we knew that they did exist once because scientists found their bones turned to stone over millions of years. The point is that I wanted to stay up to see if just maybe, the cameras might pick out a dinosaur among the jungle trees. And aside from the fact that the resolution would not pick out something that size, no one on earth could say that this wasn't what was on Mars the day before the flyby. It literally could have been jungles and dinosaurs as far as anyone here knew for sure. I was so young that the pictures would come down after my bedtime. There was some sort of show on television or possibly they broke in with the news, I'm not sure which, but they did show the pictures on television and it was night time in America. I was still awake later when my dad came to check on my brother and me. I asked what the pictures looked like and he said it looked like the moon. At the time, it was the most disappointing thing that had happened in my life. I really wanted jungle at least.

[@Skinflaps_Meatslapper]

The universe should owe you a second, happier childhood where Mars has jungles and dinosaurs :(

[@asdfasdfdos]

This is my favorite KZbin comment ever.

[@RRaquello]

One of the things I tell the young 'uns about old time TV is that when I was a kid, when you turned the TV on you had to wait for it to warm up before a picture appeared. Not for long, maybe 5-10 seconds, but you turned it on, you could see the tubes lighting up in the back, but the screen stayed blank, and then when it warmed up the picture appeared. Then when you turned it off, the picture shrunk down to a tiny dot in the center of the screen which stayed there for maybe 10-15 seconds before disappearing. This wasn't back in the 40's but actually into the 1970's. I still remember the first time I saw a transistorized TV. My older brother got one for Christmas, I think around 1973 or 74, a little Panasonic B & W, and when he turned it on the picture went on right away with no warm up, I couldn't believe it, LOL.

[@rocketsocks]

It's astounding how much we take for granted in terms of digital imaging and image processing. A lot of spacecraft from the early years of spaceflight had very janky imaging systems. The "one pixel" cameras of Pioneer 10 & 11 and the Viking landers. The CRT based cameras of the Voyagers. The CCD + digital computer with lots of memory and storage era is so luxurious in comparison.

[@martinhughes2549]

It's actually interesting how by Mariner 6/7, NASA had developed software to remove camera noise, eliminate random concentrations of higher electrical strength on the Vidicon plate where slightly higher levels of light sensitive materials had been deposited.( this mimicked higher light levels so making the image noisier) They also had software to undistort random scan line nonlinear distortions. ( that's why the images have those crosses on them, to undistort the image) and use interpolation to replace bad pixels. Or missing information. The imaging system also used compression to send an apparent higher dynamic range. Remarkable! That is one of the reasons btw that Lunar Orbiter and many soviet probes used photographic film systems, you could get sharp images which you could scan without many of these distortions. However it limits how many images you can take and is very heavy and mechanically vulnerable.

Early space science was so terribly new and wide open back then that the least morsel of information was cause to celebrate.

Of course over time we sent more probes and got better pictures and Mars, while it has craters, is a much more interesting place (in my opinion) than the moon. Back in those days, it seemed inevitable that we'd have astronauts on Mars by the 1980s but alas, the reality of the difficulty and the expense became obvious.
