How do Spacecraft Photograph the Planets & get the Images Back to Earth?

[@isaian2e]

Your videos are great. No clickbait, no nonsense, unecesary fluff. It's all very concise, well explained, educational and entertaining to watch. Great stuff.

[@or2kr]

6 hours for one image from Jupiter from an old spacecraft like Voyager? My first reaction to that was "wow, that's still quick" :D

[@Pile_of_carbon]

Sounds like surfing for... "art" back in the mid 90s. xD

[@CuriousDroid]

Yes it took a week for the first mariner images of mars

[@Jeffrey314159]

At least the Voyagers had a tape recorders to store images, Pioneer probes X & XI had to transmit their data in real time

I just turned 39 and I remember using a 300 baud modem. That's about 300bit/s on a landline. (Now I have >250Mbps on my mobile phone, so that's almost a million times faster). The fact that things have improved faster on Earth than in space, isn't that surprising. But Cool Worlds Lab have recently released a video where they talk about using the atmosphere of Jupiter to create a high-speed network in space. Really interesting.

[@t_adams]

Way off topic, but why are so many science channels on KZbin so intellectually lazy when it comes to certain subjects or questions asked by subscribers? I have a young nephew who asked two questions in particular that we looked up online and found that although it seems that the questions have been before they have been answered in the laziest fashion possible. The first question "Why can't planes fly into space?", he understands that planes need air for lift and controlled flight and oxygen for the engines to produce thrust, as do most people. Knowing this I understood that what he really means is couldn't someone just add rockets and a reaction control system to a jet and fly into space. But as we looked online including on KZbin all we found was videos, some ridiculously longer than they need to be that said the same basic thing I said in one sentence, the need for air for lift and controlled flight and oxygen to produce thrust. None of them thought to go any farther, and think maybe there was more to the question than what a three-year-old might ask and I would like to know why? The second question he asked that baffles me that no one really answered since it seems both relevant and obvious is "Why don't electric car makers put gasoline or other fuel generators in their cars so while you drive it recharges the battery once the charge gets low and once you have a full charge shut off?". Looking that up we found a lot of things about hybrids and range extenders but nothing about the question asked? It seems that many channels go out of their way to avoid the question altogether and we can't understand why? The question is clearly about a system that is not a range extender hybrid like the BMW Rex or the Chevy Volt or the Prius nor is it about the system the Fisker Karma has where for some reason you have a gas generator that creates electricity that then powers the car when the battery charge runs out but does not recharge the batteries while driving. I am sorry this comment is so long and yes I am asking the same thing to all the science channels I come across so you are not alone, but I just do not understand why so many of them including those that do deep dives into very difficult subjects seems to treat those two questions with what can only be termed intellectual laziness?

[@gregcampwriter]

The PR value of the images is important, however. The wonder on display to the general public gains support for the funding of the missions.

[@mspysu79]

The early "Flying Spot" film scanners did not use a computer to process the image, just a slow scan long persistence monitor connected to the receiving electronics, or a wideband data logging recorder(where the image stayed on the screen for seconds or minutes allowing for the image to be built up on the screen then photographed). The Vidicon tube (First called videcon ) was developed in 1950 by RCA for use in portable, low cost and industrial video equipment, variations on that design such as the Saticon and Nuvicon where used into the mid 1980's for broadcast SD and consumer use and until the early 1990's for HD video work. The Imaging CCD was developed at Bell Labs in 1970 with the first color camera using 3 CCD's being developed in 1972. RCA showed a prototype broadcast CCD camera in 1980 the same year they released the first CCD based security camera, the first production broadcast 3 CCD camera was introduced in 1983. .

[@Jeffrey314159]

Yes, this technology was widely used in transmitting film-movies to television back in 1952

We got way more pictures of Uranus and Neptune than expected because during the many years the probes were en-route people back on Earth invented better compression algorithms. We then sent the algorithms to the probes which enabled them to store and send back more images than originally planned.

Jack D'Ripa please answer the question. What is your argument and do you have evidence? If not then it’s just your personal opinion which is worthless.

[@FernandoRodriguez-pj5uh]

Jack D'Ripa Good to know you agree that yours is just an opinion because you can’t provide evidence. You don’t have evidence that contractors worked blindfolded to not know what they were doing (which just shows your ignorance on how an engineering project can work) you don’t have evidence of the actual contracts and grainy images from the 60s, well just so you know HD tv is a thing that we have been using for only a few years now and most vídeo and images from the 60s ARE grainy. So that in itself is also not evidence. Do you actually have ANY real evidence?

[@rainrainwebdesign]

Great video but I thought it was going to cover more about how the spacecraft transmit these images ... which I suppose is part of a bigger subject. Would be great to see an episode on spacecraft communications. I find it hard to imagine usable radio data coming from so far away. I am fascinated by the time lags too. The story of the lunar rover camera being remote controlled from earth to take the footage of the last 3 Apollo moon ascents is an interesting story. I think they had to send the command to pan up and out some time before the ascent engines ignited so they only got it exactly right on the last mission ... something like that. Thanks for the amazing videos.

Only time we do is when we have a true war that threatens the existence of the US. Then any con-job by a contractor would land them in prison and compromise their reputation. The rest of the time it is business as usual, fat pensions, layers and layers of contractors tripling the price of the same component each hand it goes through, 10x more employees than necessary... With the amount we pay now, if there was accountability and not a climate of pork barrel politics, and causal government ripoff, we would easily already be there.
