Scott, I am a technical illustrator for a space company in the SF Bay Area. I was wondering if you would like to do a video discussing the role art has played in aerospace in people's perception of how spacecraft work as well as communicating what spacecraft will look like (in the early days of the space race a lot of art was used to communicate what Apollo would do). It is a large part of what I do for my career and might make an interesting topic for others to learn about. -Steven
Hey Scott! I'm 19, an engineering student, I've been on an internship at the Noaa satellite facility outside DC and I've been on the GOES-S project operations team! I've been a long time fan of your videos and I was at work all day for launch and coming home to see you do a video about the GOES mission is just super fantastic!! Keep up the good work!! P.S. I even got to directly command that spacecraft during a test back in november and now its in geo transfer orbit!!! You were one of my biggest inspirations to pursue the astro field so thank you for helping me get to such an opportunity!!
I'm from Australia, & I love checking the BOM (Bureau of Meteorology) site on a daily basis. When the Himawari 8 satellite went up, it was a drastic improvement on the satellite that was used previously. I can zoom right in, & get a decent idea on the cloud cover in my general area (Sydney), & even make a reasonable prediction about cloud cover moving over the area. It's brilliant, & it's really cool to be able to see India on one side of the image, & Hawaii on the other. & the update frequency man.. The update frequency!
I used to just use their site for the east coast rainfall radars, but yeah... They've improved the functionality and quality of the imagery a LOT compared to a few years ago. It was good of the Japanese to give us access to that data.
Living in Japan and I get these via Himawaricast using a 1.2m dish/LNB. Unfortunately, the downlink capacity allows all but the blue/green bands to be downloaded.
Hi Scott, nice video and channel. This was a nice surprise! I'm actually an engineer for GOES and on the launch and operations team for GOES-S. This video was a nice surprise after waking up after the launch shift. The slide explaining the scans is actually super important for operations and I have it pinned in a couple different places at work. The images ABI brings down is incredible. During non-critical weather days we point the Meso scans at Cape Canaveral and are actually able to see rocket launches using the IR bands. It's pretty neat, you can get about 4-8 frames of the ascent. Occasionally, volcano eruptions are so powerful you can see the shockwaves ripple through South American forests. (We have a workstation dedicated to monitoring real time products. The operators love it and show us cool crap they found all the time) One neat note about GLM, it's actually really useful in predicting tornados. If you want another cool GOES instrument, I'd recommend SUVI. It's an instrument that stares at the Sun. I'd wait for a few good sun spots first though. Again great high level summary of ABI!
Great video. I try using this to show flat earths when they claim no real photos of Earth exist. Love the accent. It took me a few seconds to realize you were saying East when you said "GOES est".☺
They may look like a full disk but geostationary images only cover 81° in each direction and their weather images are only useful to 60°. That's why NOAA also has weather satellites in polar orbits. NOAA-19 covers both poles every 102 minutes and at only 870 km it gets high resolution images that cover the entire globe every 6 hours filling in the areas missed by the GOES satellites.
I think for the purposes of havin a look it can be called full disk. due to line of sight of course you can only capture up to the tangent cone from the camera to the globe. technically you would have to be infinitely far away to capture 180 degrees (or have a lens larger than the diameter of the earth)
I'm going to be in Florida in a couple of weeks from the UK. There are two launches scheduled for the time that I'm out there, a SpaceX and an Atlas. Hopefully will get to see both! Last time I saw a SpaceX launch, we went to the pier at Cocoa beach afterwards, but we were turfed out as Elon Musk had booked the pub for a private after launch party. A friend of mine was high up in Tesla so I was going to ask him to text Elon to see if we could get an invite, but I thought that would be a bit too cheeky! :-)
You know Scott, I would just like to say thank you. You make videos on so many things I had no idea about. Each of these videos manages to spark my interest in something new and interesting. I love your videos, and fly safe!
With the right hardware you can actually download NOAA weather sat images as they're being sent down to earth yourself! Should be self-evident when you think about it, but I never did, so watching a video about that blew my mind 😁
You prob cant be Joe schmo and dl all the high res imagery Would be cool thogh. I bet u need some sort of license which you pay for and even then i doubt tou get access ro all the food styff
I wish we funded putting many GOES-16 up as soon as possible as well as improving coverage over the entire Earth, including the polar and ocean regions. All observation positions should be upgraded to at least GOES-16 standard. Currently some positions have much less capable hardware. A much more detailed view of the entire global weather would significantly aid scientific studies. Similar satellites should also be sent to give good coverage of both Venus and Mars in long term high orbits.
That'd be really nice it's important it's note that the GOES Series mission is a 9 billion dollar mission that takes 10 years to get up there and another 6 months to check out.
You couldn't have a geostationary satellite looking at the poles! :-) They are, however, covered by the low earth orbit satellites, which, because they're much, much closer, don't need such technically advanced cameras.
So he mentioned being able to have it where you could have your desktop auto update to the latest image of the earth, could anyone tell or point me in the direction of how to do such a thing?
I looked at some images from that big daddy one a while back and thought it was cool. This perspective on what we're capturing was really interesting, thanks for the knowledge Dump, man.
How about looking into the requirements for Human Rated Spacecrafts. The Dragon was designed to carry astronauts but derated to just carrgo and Dream Chaser was just derated to just cargo. Is NASA's Human Rating system so stringent that private corporations can't compete?
Yeah I've got some notes for that. To be fair, no previous US human launch vehicle would qualify as human rated according to the commercial crew requirements. Dragon was never 'de rated' it was simply designed first as cargo and then later Dragon II became the pitch for commercial crew.
nardgames that's true but I'm sure NASA is not going to send people into deep space without some shake down flights. The only thing available right now would be cew changes at ISS.
Different ratings for different jobs. It's not a simple question of "is it safe, yes no?". They have strict ratings for the commercial crew flights, because 3 souls go up and down every ~3 months. It's a LOT of human life being transported, on a tight schedule that never stops. That's why the ratings for them are so insanely strict.
Cool to see Harris featured on one of your videos. Their night-vision division sponsors a "dinner in the dark" for a local charity that helps vision-impaired and blind folks in my area.
In Zurich, where I live exists a small Restaurant in which only blind people serve and most of the kitchen crew as also blind. And yes, the whole dinner (exept the closets and kitchen) are completly dark. It is quiet an experience that everyone should make
The US should use Molniya or Tundra orbits for their satellites. These are highly elliptical orbits that can be very useful for getting coverage of higher latitudes. While satellites in Geostationary orbits can only point to the equator, satellites in Molniya and Tundra orbits can get you images of the continental US PLUS Alaska and the Arctic.
JJayzX www.goes-r.gov/users/grb.html Goes rebroadcast allows for anyone with a properly sized antenna to get all the data. Works great when you are out at sea and need the weather forecast
There are 400MP cameras... They use sensor shifting of a 100MP sensor to do superresolution. If you stich a few images you can get much higher resolution.
That's exactly what these satellites do as well. Except instead of shifting the sensor, they shift the light path. The result is of course identical (it's the same thing). Stitching the image is also the same thing - on an electronics level, that's already what a sensor fundamentally does.
While scrolling through the image at the start, the video seems to jump a bit occasionally, as if your machine couldn't quite keep up with loading in the next bit of texture and skipped a few frames.
How do we find out what satellites are out there broadcasting in ways we can capture? Are there any satellites which broadcast the Southern hemisphere where Antarctica is clearly visible?
Hi Scott, very cool and informative video. When you showed the east/west satellites I got to thinking about how hard it is to do fixed spacing of satellites and/or multi satellite launches. Do you have a video where you go into that? Thanks and kind Regards, Wulf
It's a reality that trillions of gallons of super heated water vapor is released into the atmosphere daily.... Mainly through the power plant grid, and also some refineries and other various industrial areas. It's clear to see the massive bursts over land.... Naturally, nobody talks about that, check out WeatherWar101's channel, they have painstakingly detailed this process for years.
I can't wait to finish my electrical engineering degree and computer science degree. My dream is to work on space exploration stuff. I live near ATK orbital. Sadly they don't do as much as they used too.
Matthew C I worked for ATK before the split off of the aerospace div (military equipment) good company, but there was always talk of divisions splitting, so I found it nerve wracking. Good luck!
You know they're gonna latch onto the word "disc", once spoken, once shown in text, for dear life. Because if they don't have the slightest clue what i refers to in this context they can at least pretend that it was some slipup of the most extreme conspiracy ever imagined.
A digital camera and your smarthphone camera create computer-generated images (CGI) as well does that mean all it shows is fake? Ultrasounds commonly known for scanning the womb also generates CGI, MRI machines as well. The flat earth uses "fake CGI" as a weapon to destroy any factual evidences shown to them.
While impressive technical achievements it always bugs me how much the performance of these fancy aerospace systems lags behind consumer tech. im sure there are very good reasons for why we cant just strap commercial of the shelve stuff to satellites and I would definitely like to see a deep dive on that subject but Its still quite odd to think about. like sure the resolution is pretty good but the overall amount of data collected per unit of time seems decisively unimpressive compared to consumer tech even when considering there are 16 channels instead of 3 and the bit depth is probably something like 16bit. consider that a modern mirror less camera can have 16bit capture at 40Mpx in the palm of your hand. assuming you need to take one frame for every spectral band and 10 to capture the whole disk and match the 400Mpx resolution that means that in 160 shots of a handheld consumer device, using maybe 10watts of power, you could match the data captured by this car sized state of the art satellite using 4KW. If our camera was able to work at 2fps it would capture the full 16 bands at 400mpx in 1min 20sec. more than 10 times faster than our satellite! I wonder what nuances go into these systems that make them lag so far behind what a back of the envelope calculation given available tech would suggest. after all a huge amount of thought must have been put into them.
Solar radiation destroys/disrupts electronics - modern smaller and denser electronic is more vulnerable than older one. There is also matter of power, solar panels are not exactly powerful and they do decay over time.
randomnickify while those factors sure have some impact I doubt they fully explain it. solar power is actually pretty damn good once you are in space and dont have to deal with clouds (according to wikipedia this satellite actually has an impressive 4000 watts available) and If radiation required such much less dense electronics its seems odd that you couldnt just use dense electronics and spend the weight savings on shielding. I think another part of the explanation is the time it takes to get something flight rated. after all you better damn well make sure everything is incredibly reliable before you book a rocket launch. though again I have to wonder wether bringing down cost would actually impact reliability all that much (80/20 rule and all) and wether It might be a viable strategy to have lower cost, smaller satellites that ocasionally fail but are cheaper to update and replace
I dunno... dead satellites and other space waste are a real problem as-is. Better be careful with what you shoot up into an orbit where things don't come down by themselves.
Have you noticed the aliasing of circle of Earth on animation (ladder-effect?) - Scott, would you be interested to make a technology video on why this happens? )
This is not a flat earth question, just want to make that clear - but is it not true that the image of earth used in Himiwari 8 is actually a NASA image which the cloud data is superimposed on top of?
This is not the case. This video explains the capture process in detail, you can go and see the raw greyscale r,g & b channels and see the landmasses are visible.
watching this footage I can see dark bands at dawn and dusk, do you think this lends credence to the old saying "it is always darkest before the dawn"? I always thought it was to do with the human eye having to filter out the twilight, when the sky is brighter than the earth's surface and so the eye filters out more light and you can't see as well despite it actually being the brightest part of the night. then of course, it has occurred to me that it might be purely a metaphor with no truth to it whatsoever. but then I can see it in this footage so now I'm wondering if maybe it is true, maybe it's something to do with the camera filters (the camera needs to be protected from overexposure just as much as the human eye) or maybe something I haven't thought of.
These images are composed of many horizontal scans, and we can see the night portions are using a different palette mapping than the day portions. Rather than using some sharply-defined switchover in mapping between day and night, they are using some form of interpolation or gradual change, resulting in these darker vertical bands right at the terminator. If they didn't do this, then we'd see a really ugly, sudden changeover between day and night.
Here is the way it works. Each photo is 11,000 x 11,000 square with the earth within the square. If the Sun or the moon show up it is usually in one of the four corners of the photo. If it is the Sun and shining directly into the camera, those sensors are turned off so that the photo will not be blown out by the glare of the Sun. If the Moon shows up in one of the corners then it is only for one frame out of the 144 per day that the Himawari takes. Here is one example of the Moon showing up in one of the four corners. It is just one photo out of 144. It was shot September 02, 2015 at 3 pm Japan time. The Moon will be in the upper right-hand corner. Be patient.

Mindblowing stuff! Thank you for explaining it. I never tire of seeing science in such awe-inspiring action! Btw, if you want to see how these images get misused, go to Cool Hard Logic. He does a series called World of Batshit. I can't remember the name of the episode in which this is mentioned (and because I'm writing, I can't go look!) but some are plainly not related to this. Having said that, I recommend watching all of them for the lolz and that moment when you think it's got to be a hoax but realise it isn't. That's the moment you open the bottle of Scotch and forgo the glass ;-)
That animation at the end was adorable. Always have to get your tongue at the right angle when making adjustments.
My wife doesn't understand why I do this. But it works!
Don't turn it on, take it apart.
Ah, you got the Dave reference. :)

I rarely comment, however I would be extremely interested in learning about this.
Yes please, That would be so interesting
Great idea! It could talk about how biased ideas came through the representation of science and space too.
I'm the webmaster on the GOES project. And have been working on the project for 11 years now. Really cool seeing you talk about this.

the ULA put it into geo transfer orbit. the next three weeks we're doing a series of apogee burns to get it into geo

My brother works at Harris as a engineer! He designs these cameras!
I have so many questions I would love to ask those guys.....
Scott Manley he's really cool, I'll share this video with him!
Scott Manley he actually touched part of Goes 16!
Joke's on you: 'Maffs' has 2 fs.

Again great high level summary of ABI!
Any chance you could do a video on the James Webb telescope?
Final Spartan the jwst needs a series to explain.
I just finished up building a GOES-16 ground station to receive the images directly off the satellite. The images are fantastic.
That is one of the most beautiful things I have ever seen. That and Anne Hathaway.
Great video. I try using this to show flat earths when they claim no real photos of Earth exist.
Love the accent. It took me a few seconds to realize you were saying East when you said "GOES est".☺
@@aurevoirugootubee3927 , the knowledge about the Spherical Earth is observable, testable and repeatable.

I'm in Cocoa Beach, Florida right now. So I can watch the launch of GOES-S Live.
I am excited for it.
And I am jealous.
It was awesome, but why was there no sonic boom?
From what I've been told, you won't hear a sonic boom while the craft is moving away from you. So, only during the rare shoreside SpaceX landings.
I'm going to be in Florida in a couple of weeks from the UK. There are two launches scheduled for the time that I'm out there, a SpaceX and an Atlas. Hopefully will get to see both! Last time I saw a SpaceX launch, we went to the pier at Cocoa beach afterwards, but we were turfed out as Elon Musk had booked the pub for a private after launch party. A friend of mine was high up in Tesla so I was going to ask him to text Elon to see if we could get an invite, but I thought that would be a bit too cheeky! :-)

Digging the simple animation at the end, kinda cute.
The changes of the sunlight's angle are really visible on that Himawara 8 satellite time lapse video.
I looked at some images from that big daddy one a while back and thought it was cool. This perspective on what we're capturing was really interesting, thanks for the knowledge Dump, man.
How about looking into the requirements for Human Rated Spacecrafts. The Dragon was designed to carry astronauts but derated to just carrgo and Dream Chaser was just derated to just cargo. Is NASA's Human Rating system so stringent that private corporations can't compete?
Yeah I've got some notes for that. To be fair, no previous US human launch vehicle would qualify as human rated according to the commercial crew requirements. Dragon was never 'de rated' it was simply designed first as cargo and then later Dragon II became the pitch for commercial crew.
Scott Manley so is the Orion Spacecraft just another NASA's theoretical pursuit?
Orion is for deep space exploration, commercial crew is for low earth orbit missions.
nardgames that's true but I'm sure NASA is not going to send people into deep space without some shake down flights. The only thing available right now would be cew changes at ISS.
Different ratings for different jobs. It's not a simple question of "is it safe, yes no?". They have strict ratings for the commercial crew flights, because 3 souls go up and down every ~3 months.

Goes rebroadcast allows for anyone with a properly sized antenna to get all the data. Works great when you are out at sea and need the weather forecast
the lightening video was incredible
So what level of technology do they need to predict tomorrow's weather with greater than 50% accuracy?
That depends on where you are in the world, some places are easy to predict, others, like UK and San Francisco are especially unpredictable.
"Master Summoner" Level 6
We would need to be at least a Type III civilization..
Love that "glare" going along the equator during daytime, some kinda reflection off the atmosphere?
no, the ocean
One of your best vids to date Scott, awesome, thanks!
5:40 "Mt. Cinnabon"
What next? Pillsbury Plateau?
that was super exciting and informative! thanks Scott!
at 2:04 you can see cyclone gita form and the pass over new zealand in the bottom right
5:36 Oh awesome, they got pictures of my neighborhood burning from space
Quality video, Mr Manley. Didn't even know that I didn't even know about this stuff. I wonder how much of this tech ends up in military satellites.
I suspect it's the other way around :)
I completely agree. That SBIRS constellation is a helluva machine.
Check out the cartosat series of imaging satellites. The data started coming up a few weeks back.
Fantastic explanation as usual. Thank for the great vid.
Insanely good video.
that's not the full image of the globe, Scott, its 48% at best

yes, great job thank you another science video...
Amazing footage
Man, thought this was a video from Seeker (not sure why), so didn't bother to watch it..
Then I saw it again, and it was from Scott. Instant click!
Today GOES-17 / GOES-S / new GOES-West joins the crew!
3:37 Moon photobomb!
That is awesome. Thanks!
How do we find out what satellites are out there broadcasting in ways we can capture? Are there any satellites which broadcast the Southern hemisphere where Antarctica is clearly visible?

Hi Scott, very cool and informative video. When you showed the east/west satellites I got to thinking about how hard it is to do fixed spacing of satellites and/or multi satellite launches. Do you have a video where you go into that? Thanks and kind Regards, Wulf
Great stuff, Earth observation from space is sooo important. How about doing a video on Landsat, Modis, Sentinel satellites. \m/
We need a website that combines all available live images of the globe and paints those on a sphere... Then have that as a screensaver.
3:16 Wow 😲 u literally can see the tornado building up and hitting japan 😮😮😮👌👌🙃🙃🙃
Philippines just keeps on getting barreled down with cyclones in the full disk timelapse part lol

another great video :)
Another great vid
Very, very cool. Like, like, like!
Amazing.
Thanks
7:06 Is it some kind of observational artefacs or the lightning really trace lines like this (as the clouds are stretched)?
Finally, an image large enough to fill my ego.
More videos like this!
Is it possible to see a vedeos inside the home from settelite if so how so and what apps used to see such footage
That’s like the largest scale most high tech most expensive time lapse for earth
Anyone have a link for setting this up for the screensaver or background in real time like he talk about?
Cool video btw!
While impressive technical achievements it always bugs me how much the performance of these fancy aerospace systems lags behind consumer tech.
im sure there are very good reasons for why we cant just strap commercial of the shelve stuff to satellites and I would definitely like to see a deep dive on that subject but Its still quite odd to think about.
like sure the resolution is pretty good but the overall amount of data collected per unit of time seems decisively unimpressive compared to consumer tech even when considering there are 16 channels instead of 3 and the bit depth is probably something like 16bit.
consider that a modern mirror less camera can have 16bit capture at 40Mpx in the palm of your hand.
assuming you need to take one frame for every spectral band and 10 to capture the whole disk and match the 400Mpx resolution that means that in 160 shots of a handheld consumer device, using maybe 10watts of power, you could match the data captured by this car sized state of the art satellite using 4KW.
If our camera was able to work at 2fps it would capture the full 16 bands at 400mpx in 1min 20sec. more than 10 times faster than our satellite!
I wonder what nuances go into these systems that make them lag so far behind what a back of the envelope calculation given available tech would suggest. after all a huge amount of thought must have been put into them.
Solar radiation destroys/disrupts electronics - modern smaller and denser electronic is more vulnerable than older one. There is also matter of power, solar panels are not exactly powerful and they do decay over time.
randomnickify while those factors sure have some impact I doubt they fully explain it. solar power is actually pretty damn good once you are in space and dont have to deal with clouds (according to wikipedia this satellite actually has an impressive 4000 watts available) and If radiation required such much less dense electronics its seems odd that you couldnt just use dense electronics and spend the weight savings on shielding.
I think another part of the explanation is the time it takes to get something flight rated. after all you better damn well make sure everything is incredibly reliable before you book a rocket launch.
though again I have to wonder wether bringing down cost would actually impact reliability all that much (80/20 rule and all) and wether It might be a viable strategy to have lower cost, smaller satellites that ocasionally fail but are cheaper to update and replace
I dunno... dead satellites and other space waste are a real problem as-is. Better be careful with what you shoot up into an orbit where things don't come down by themselves.
Nice.
awesome
Scott says you can make this a screensaver but Ive search around and couldnt find anything on it. Anyone know where I should be looking?
How do I automate live pictures to be my background?
How can you set up the screensaver to automatically crawl such images?
Any info on getting these as a screensaver? I've wanted that forever!
Scott how do you convert NetCDF files into raster images without spending money on scientific data processing software?
I freaking love this planet! She's so damn cute!
Have you noticed the aliasing of circle of Earth on animation (ladder-effect?) - Scott, would you be interested to make a technology video on why this happens? )

Temporal frequency? Isn't that a tautology? Or did I miss something? O.o
This is not a flat earth question, just want to make that clear - but is it not true that the image of earth used in Himiwari 8 is actually a NASA image which the cloud data is superimposed on top of?
This is not the case. This video explains the capture process in detail, you can go and see the raw greyscale r,g & b channels and see the landmasses are visible.
Are these images able to be pulled down with the right receiver and a freeware decoder like (NOAA 15,18,19,etc)?

watching this footage I can see dark bands at dawn and dusk, do you think this lends credence to the old saying "it is always darkest before the dawn"?
I always thought it was to do with the human eye having to filter out the twilight, when the sky is brighter than the earth's surface and so the eye filters out more light and you can't see as well despite it actually being the brightest part of the night.
then of course, it has occurred to me that it might be purely a metaphor with no truth to it whatsoever.
but then I can see it in this footage so now I'm wondering if maybe it is true, maybe it's something to do with the camera filters (the camera needs to be protected from overexposure just as much as the human eye) or maybe something I haven't thought of.
These images are composed of many horizontal scans, and we can see the night portions are using a different palette mapping than the day portions. Rather than using some sharply-defined switchover in mapping between day and night, they are using some form of interpolation or gradual change, resulting in these darker vertical bands right at the terminator. If they didn't do this, then we'd see a really ugly, sudden changeover between day and night.
when weather is involved it's thicc
how do you get those real time on screen saver?
or you could just download the images directly off the satelite..very easy with a SDR
shouldnt we be able to see the sun on the other side when the camera is looking at the night side of the earth?
The camera doesn't capture images when the sun is in the frame, it was literally exlained in the video
Here is the way it works. Each photo is 11,000 x 11,000 square with the earth within the square. If the Sun or the moon show up it is usually in one of the four corners of the photo. If it is the Sun and shining directly into the camera, those sensors are turned off so that the photo will not be blown out by the glare of the Sun. If the Moon shows up in one of the corners then it is only for one frame out of the 144 per day that the Himawari takes. Here is one example of the Moon showing up in one of the four corners. It is just one photo out of 144. It was shot September 02, 2015 at 3 pm Japan time. The Moon will be in the upper right-hand corner. Be patient.

6:21 UW represent! Go badgers!
where the hecc can i get the original resolution images?
3:23 is that a cyclone up over Japan?
Love how the Moon looks in the background at 4:20
Woopert Yeah such detail of the tiny moon, where are stars not 1
@@johnd1466 The imager exposure time isn't suited to capture stars.
Cool andf thanks :~)
Hell yeah!
sweet
Mindblowing stuff! Thank you for explaining it. I never tire of seeing science in such awe-inspiring action!
Btw, if you want to see how these images get misused, go to Cool Hard Logic. He does a series called World of Batshit. I can't remember the name of the episode in which this is mentioned (and because I'm writing, I can't go look!) but some are plainly not related to this. Having said that, I recommend watching all of them for the lolz and that moment when you think it's got to be a hoax but realise it isn't. That's the moment you open the bottle of Scotch and forgo the glass ;-)
Its called World of Batshit - #5: Space Denial. ua-cam.com/video/tMtwSVO0PQk/v-deo.html
What's wrong with Cool Hard Logic?
Cool, I will link to this video, if someone claims the earth is flat ;) Hehe. In any case, thanks for some cool videos.
coming soon to a smartphone camera near you..
