I think this is the best "All-in-One" Random Tables product you can get for Sci-Fi settings. One thing I'm missing here is a table for events on planet's surface. There is a Planet Event table, that somewhat covers it, but a lot of outcomes are planet-defining (like toxic atmosphere, ocean planet with some horrific creatures beneath the surface etc.), which is a good thing if you look for a adventure ideas, but not that great if you want to drop a random event on a planet that you've created.
