Will there be a place where they can be downloaded? A live Planet Earth desktop wallpaper would be pretty great.

I wrote a script which downloads the latest image in a large resolution[0]

If you can set your wallpaper from the commandline, or have the wallpaper refresh from an image on disk, you could use it for a live wallpaper.

I'm also going to have the scraper check if the image has changed every 10 minutes and have it update at [1] if it has, but the image will only be in 1,100px x 1,100px resolution.

I wrote a simple shell script[0] to scrape and output the latest image. It uses the tiles from their online satellite map[1], and can output images in increments of 1x1, 2x2, 4x4, 16x16 tiles (each tile being 550px by 550px). Here is an example with 2x2 [2] If you have any suggestions or bugfixes, feel free to fork or comment. EDIT: Also works for a single tile[3], also clarity. [0] https://gist.github.com/Syrup-tan/…

Is anyone busily tapping away at a Windows port of this? I'm enthusiastic, but it would take me all day/week

I wish there were a pair of these satellites separated by a couple thousand miles/km, so we could view these images with next-gen, hi-rez VR goggles and see the surface and cloud topography with enhanced depth.

Earlier quoted context omitted.

Its already assumed that there is little or no privacy in public spaces.

Privacy is on a sliding scale. There are certain assumptions we rely on when we go out in public. Imagine, for example, some future where you were effectively under constant surveillance when in "public". Where your every action, every movement, every utterance was recorded, categorized, transcribed, data mined, and then put into a feed that anyone could subscribe to. That's what the complete absence of public privac…

So imagine London?

So my first thought was (will this replace the doves by space labs). Which was an earlier story on HN. https://news.ycombinator.com/item?id=8158295 It won't because these are geostationary satellites (if I read the post correctly). So you'd need at least 3 of these to get a good image and that's not even considering some of the bigger issues with this. I also don't think the resolution is on par. But the images will…

Uhhh, this spacecraft is for a totally different application.

Planet Labs doves are in LEO for low earth observation. This Japanese one is a weather satellite to monitor the area around Japan.

the max tile value is actually 20x20 (i.e http://himawari8.nict.go.jp/img/D531106/20d/550/2015/07/10/2...) making it the 11000x11000 res.

Yeah, living in London you have several cameras looking at you permanently. You can see a bunch of them via the TFL api as well.

Is it common to lock a satellite into a stationary orbit?

Satellite TV and communications satellites commonly do this -- otherwise your satellite dish would have to track the satellite across the sky as it moves.

Defense Support Program satellites are also in stationary orbits so they can watch fixed regions for nuclear missile launches with infrared cameras.

Just give it a shot, you could translate it line for line into Ruby, and use ImageMagick or something. Don't sell yourself short, it won't take as long as you think!
