Skybox rebranded to Terra Bella on Mar 8th 2016. They were acquired and placed in the Geo organization (Maps) so they aren't just floating about as a one-off: http://spacenews.com/googles-skybox-imaging-has-new-name-bus...

It's funny, they're named after the street that their office is on. Which is where their office was the whole time, but the new name is actually a better fit for what they do than the old one was.

I'm also curious about this. Isn't this exactly the kind of project Alphabet was created to wrap? i.e. something not related to Google's core business but still under the corporate umbrella?

Terra Bella is under Geo, which is where Maps resides. Seems like a pretty good fit to me, given that satellite imagery is presented in Maps. Why do you think Terra Bella should be in Alphabet?

That makes perfect sense actually. I was erroneously thinking of Terra Bella as a standalone project instead of as an extension to one of Google's core products.

My guess is it would be, but hasn't been formally spun out yet?
