Here's a visualization tool I've been working on to explore the global swath coverage of 1+ million declassified spy satellite images. https://t.co/oEY7N8NpyE ๐งต
@CORONAGAMBIT@aaronbateman22@shell_jim Itโs the declassified imagery with available scans highlighted. I built the site in mid-2022 and didn't realize that USGS has added ~150k more images online since then. Mostly KH-9 with ~4k more just from 1219-3. Thanks for spotting that, I've updated the site with newer data.
@steffanwatkins C-GGRD #C0563E flew a similar pattern at the same location in Aug 2023.

I have a team of straight-up wizards working for me here at @umbraspace. A peek at something we've been working on - change detection products. In this shot, we're showing the changes at #BurningMan from Wednesday night to Friday morning. Blue = new objects, red = fled / moved.
As a (former) District resident, I was always annoyed that satellite imagery of DC was just the National Mall and I could never say "hey I can see my house from here!" So I tasked 4 spotlight images in a row to get the full N-S extent of NW DC in glorious #SAR from @umbraspace
What is NEST?
As Jeffrey Richelson put it, "if a similar organization did not exist in the real world, Hollywood probably would have created one.โ

One of the more impressive @planet images Iโve had the privilege of working on lately. All 9 Himalayan 8,000-meter peaks in one view, taken from over Afghanistan.
Last night I captured an incredibly difficult shot: ISS transiting the moon, while gently kissing Tycho crater as it flies by at 5 miles per second. That crater is 53 miles wide, so while the station almost looks like it's orbiting the moon it's actually 1000x closer to us.
New hardware close-up! @BallAerospace has installed & aligned Roman's element assembly wheel into the Wide Field Instrument. Through elements like Roman's grism & prism, cosmic light can be dispersed into rainbow-like measurements!

@Harry__Stranger Your project was a big inspiration for this! The spreadsheet and @Soar_Earth uploads are what originally led me to the EarthExplorer data and got me curious about these archives.
