There should be a button in the lower left part of the planet window that says "scan planet".

This is the manage planet window?  Where I decide what improvement to make on which hex?  If so, I looked at a couple and didn't see it.  Will it only appear on planets I need to scan?

Yes, it's on the manage planets window. It appears in the "Available Projects" list. And my mistake, it's now on the lower right. Unless it's been changed recently it should appear on all your core planets until you scan enough of them, then it will disappear.

Thank you, that worked.
