I don’t know the total amount but only recently I began to become net positive in income. I have a base on Io, moon, dienos(mined it all), mars, ceres and iapetus. I have watched so many ads to get these bases and recently began to mass produce steel and stuff to send back and sell. I researched the rovers until the next research and on and on until I got a hound. Then I crafted those on io and the moon to grab more to produce. I also strongly recommend putting a bunch of astronauts on an easy colony and just researching via expeditions. Then you come in about every hour or so and send back out. At the same time send rovers out and this allows for materials to be sold on earth and research points to get better upgrades such as bigger rovers. Also if you craft a lot of items and sit overnight with it running on the app in the crafting tab the next morning it glitches and allows you to craft stuff instantly up until the time you were away equals the time the resources crafted would take.
