>The prompt products are alerts, issued within 60 seconds of observation, about objects that have changed brightness or position relative to archived images of that sky position. Transferring, processing, and differencing such large images within 60 seconds (previous methods took hours, on smaller images) is a significant software engineering problem by itself.[64]

Interesting, I'm guessing secret spy satellites?
- kkylin 1y ago"Let's look for spy satellites / orbiters" was an "application" I wondered about. My second thought about this was: maybe the US (and possibly other countries) already have something like this, but classified?
- dekhn 1y agoThe US already has a very sophisticated system for this. https://en.wikipedia.org/wiki/United_States_Space_Surveillance_Network https://en.wikipedia.org/wiki/United_States_Space_Surveillan...

- ianburrell 1y agoThere is the Space Surveillance Telescope [1] in Australia. It is similar military telescope for space tracking. It is only 3.5m compared to LSST 8m. 1: https://en.wikipedia.org/wiki/Space_Surveillance_Telescope https://en.wikipedia.org/wiki/Space_Surveillance_Telescope

- gmueckl 1y agoI expect a lot of events to get filtered that foreign governments expect to stay reasonably secret, even if they aren't friendly with the US. It's a game. The thing that really saddens me is that the military gets to filter the data first and scientists only get to see the already manipulated data instead of a raw feed from their own instrument.
- prpl 1y agoit’s spy satellites (mainly domestic). In some cases, they don’t actually need to be removed, just embargoed until orbital change.
- BurningFrog 1y agoI thought all satellites already have known orbits? Both because they can't be made invisible, and because you need to avoid collisions.
- Xss3 1y agoMany can (and do) change orbits.
