This is funded by the National Science Foundation. 1800 NSF employees are being evicted from their office building by the Housing and Urban Development.

The title should be corrected to "Earth's", which is the original NYT headline. "Earths" would mean more than one Earth.

Why do they do this? One of the political divisions is not like the others (one of them is also a colloquial name):

"which will be transferred and processed at facilities in California, France and Britain."

Keep it consistent, else I don't know what else you're playing fast and loose with.

I'm looking for more sources of information about how the data is scrubbed of NRO satellite data.

Scott Manley mentioned in his recent video that archived data is not scrubbed, but the alerting pipeline is. I would think that artificial satellites were already scrubbed, but I suppose the National Reconnoissance Office and Department of Defense could their own filter.

20 TB of data every night, incredible. 15 seconds per image and 2 seconds to download.

Hopefully those hi-res images will help us answer the many questions we have, provided the answer is in the south!

> 20 billion galaxies and 17 billion stars…

Are there more visible galaxies than stars? (Discounting of course that those galaxies are comprised of stars.)

The idea of cataloging billions of galaxies and spotting millions of nightly changes feels like a new chapter in skywatching

Fucking Starlink.
