Mars:
Focus on economy first. First thing is to research are carbon and iron mining. Make 1-2 outposts. Do not need to rush all the other stuff. Once you get good cash flow, then everything will be easier. For culture, sacrifice population growth for financial growth early as you really need the income. You can just change it later if you want and you don't really need population growth. I stuck with 100 people only for a long time.

Note: Please check all levels (pressure, oxygen, heat, etc.) and make sure that they are not increasing or descreasing and if they are, at least not by a huge amount. Also take note that you shouldn't increase your water level because if water levels increase, the amount of outposts you can place on the map will be limited.

Next step... Research.
Research silver then a spaceport. This will boost your income by a lot.

Next is a palladium mine.
If you make a palladium mine, it will be expensive (2m) or more per mine but you can make it cheaper. First, scan for palladium and silver on the outposts you currently own. If there are decent ones then demolish ALL your carbon and iron mines and exchange with palladium. One of my outposts earns 35k. I didn't upgrade any of my mines. You don't need to but you can if you want. I don't like the upgrade because the mine depletes faster and it gets expensive to make a new outpost.

Tip for mining: start scanning with the most expensive first so that you don't make the mistake of putting a carbon mine on a very good silver mine location. This will maximize your earnings and not waste time and money.

Next: Click on the satellite option which would be available once you have a spaceport. 2 sattelite colonies on Phobos and Demios. Just get some people living there (550 population each as my personal recommendation) and somehow they will get random bonuses that make you earn more.

I am still a long way from achieving victory but I am making 300k per minute and the only thing that is stopping me from developing faster is the research and construction times.

Once you unlock the space port, crazy expensive but amazing construction upgrades will be available costing around 25-50m each. You can see them on the satellite options. I am planning to do the one that you can freely adjust your culture points to make me more flexible especially with construction and research times or for when I need money faster.

The game tutorial is enough. It isn't that hard to figure out. It's part of the game to figure things out so the tutorial should not spoon feed you!
